Description

  The present invention relates to a waste collection device that converges and discharges waste conveyed from a waste transportation device by a predetermined amount.

2. Description of the Related Art Conventionally, a waste collection device that collects waste discharged from a waste delivery device by a predetermined amount and discharges it is known. Such an exhaust and focusing device is provided with a focusing rod that receives the waste that is conveyed from the discharging and conveying device, and is disposed behind the focusing rod and guides the exhaust toward the focusing rod. By supporting the guide rod that prevents the fall of the waste box so as to be able to rotate in the vertical direction, the convergence rod and the guide rod are biased by a spring and rotated to a waste convergence position that intersects each other. When the exhaust pipe is focused on the focusing rod, and the weight of the exhaust rod reaches the predetermined weight, the focusing rod and the guide rod are rotated to the discharge position facing the rear of the machine so as to be separated from each other against the spring, The upper waste is configured to be discharged onto the ground at predetermined intervals as a predetermined amount of waste bundle. (For example, refer to Patent Document 1).
Japanese Utility Model Publication No. 63-2439

  However, in the conventional rejecting and focusing apparatus, the focusing soot is maintained so as to be oriented substantially in the horizontal direction and rotated downward by the weight of the rejecting so that only the focusing soot is conveyed from the rejecting and conveying device. Since it was configured to catch the coming waste, all the load of the waste that is focused between the focusing rod and the guide rod is applied to the focusing rod and supported by the spring force. There was a risk of lowering.

In addition, when the size of the combine grows and the running speed increases during cutting and threshing, the amount of harvest per unit time increases, and along with that, the amount of waste per unit time transported by the waste transporting device also increases. When the focusing rod and guide rod rotate back from the discharge position to the focusing position, the predetermined weight is reached immediately, or the exhaust weight on the focusing rod reaches the predetermined weight before it completely returns to the focusing position. It happens that excretion is released continuously. When the discharged waste discharged in this way spreads widely on the ground, it is difficult to understand the boundary when collecting as a bundle, and the size of the bundle is disjointed, and the effort for separation is increased.
Therefore, in view of such a problem, the present invention provides a rejection focusing device that can discharge the focused rejection without disturbing it even if the amount of rejection per unit time increases.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

  That is, according to the first aspect of the present invention, a focusing rod that catches the discharging rod conveyed from the discharging and conveying device, a guide rod that is disposed behind the focusing rod and guides the discharging rod toward the focusing rod, and the focusing rod A squeezing and focusing device comprising driving means for pivotally turning the heel and the tip of the guide heel so as to focus and discharge the scum at a predetermined amount. Extending from the rear of the aircraft diagonally rearward and downward and bending upward from the middle of the fuselage, and when the focusing rod and the guide rod intersect and close, the rear end of the focusing rod is approximately vertically below It is configured to go in the direction.

  According to a second aspect of the present invention, means for measuring the amount of waste conveyed from the waste transporting device is disposed in the waste transporting device, the waste amount measuring means and the driving means are connected to the control means, The focusing rod and the guide rod are configured to open and close according to the amount of the rod.

  According to a third aspect of the present invention, the measuring means is constituted by a device for measuring the vertical movement amount of the nip disposed below the evacuation transport device.

  As effects of the present invention, the following effects can be obtained.

  In claim 1, when the amount of waste per unit time increases, even if the rotational speed of the guide rod and the focusing rod increases, the focused waste is dropped vertically so that the waste remaining on the focusing rod is reduced. The soot can be eliminated and discharged with each focused waste. Moreover, since the waste is less likely to disperse than when it is discharged obliquely downward, it is easy to visually check the boundary between the wastes.

  According to claim 2, it is possible to make the concentration of the rejects close to a constant even when the amount of rejection is less than the initial set value, such as when the number of harvesting stripes is less than the maximum number of possible cuttings of the main body. Become.

  According to the third aspect of the present invention, since the amount of waste that is actually conveyed can be detected, even if the amount of waste is smaller than the initial set value, the convergence of the waste can be made closer to a constant value. It becomes possible.

Next, embodiments of the invention will be described.
FIG. 1 is a side view showing the closed state of the waste and focusing device, FIG. 2 is a side view showing the opened state of the waste and focusing device, FIG. 3 is a block diagram showing a control mechanism of the waste and focusing device, and FIG. FIG. 5 is a side view showing a state in which the conventional squeezing and focusing device shifts from the closed state to the closed state again, and FIG. 6 is a side view showing the squeezing and focusing device of the present invention from the closed state. FIG. 7 is a side view showing a closed state of the waste collection device in another embodiment, FIG. 8 is a side view showing an open state of the waste collection device in another embodiment, FIG. 9 is a rear view of the waste collecting device according to another embodiment, and FIG. 10 is a rear perspective view of the combine equipped with the waste collecting device according to one embodiment of the present invention.

  As shown in FIGS. 1, 2, and 10, at the rear part of the combine 1, a waste transporting device 2 that transports threshed waste from the feed chain to the waste transporting chain 3 and the pinch 4 to the rear. And a waste cutting device 5 that enables the waste conveyed by the waste conveying device 2 to be cut by the rotary blades 6 and 7 to be discharged to the outside. Then, a waste condensing device 10 is provided behind the waste cutting device 5 behind the waste transporting device 2, so that the pinch 4 of the waste transporting device 2 can be expanded and contracted and the waste cutting device 5 can be thrown in. By opening and closing the cover 8 covering the mouth, the waste from the waste transporting device 2 is alternatively transported to either the waste cutting device 5 or the waste converging device 10.

  The squeezing and focusing device 10 squeezes the sewage transported by the squeezing and transporting device 2 by a predetermined amount and discharges it to the outside. A focusing rod 11 attached via a support frame 15 extending in the direction, a guide rod 12 disposed behind the focusing rod 11, and a driving means disposed between the focusing rod 11 and the guide rod 12. 13 or the like.

  That is, when the rejecting and focusing device 10 is in the focusing position (closed state) shown in FIG. 1, the shaft 16 is rotatable in the left and right horizontal direction at the lower end portion of the support frame 15 attached to the rejecting and cutting device 5 or the machine body. A plurality of rotating arms 17 are supported on the shaft 16 so as to protrude obliquely downward and fixed at predetermined intervals in the left-right direction so as to be integrally rotatable. However, the shaft 16 can be cantilevered with respect to the support frame 15, and the support frame 15 can also be configured to be turnable left and right in accordance with the discharge direction about the vertical axis. Then, the end of the focusing rod 11 is fixed to the rotating arm 17 so that the focusing rod 11 can be rotated in the vertical direction around the shaft 16.

  Further, an arm 18 is fixed to the left and right side ends of the shaft 16 so as to protrude rearward, and can be integrally rotated. When the arm 18 is rotated, a rotating arm 17 on the shaft 16 is also provided. It is comprised so that it may rotate simultaneously.

  The support frame 15 has an upper part bent backward so that the support frame 15 has an inverted L shape or an inverted “let” shape when viewed from the side, and a shaft 21 is rotatably supported at the upper rear end portion. A plurality of rotating arms 22 are provided so as to be integrally rotatable at a predetermined interval. Then, the base end portion of the guide rod 12 is fixed to the rotating arm 22 so that the guide rod 12 can be rotated up and down around the shaft 21 behind the focusing rod 11. Note that the number of focusing rods 11 and guide rods 12 may be the same. Moreover, the space | interval of the adjacent guide rod 12 and the guide rod 12 can also be adjusted with the length of a rod.

The guide rod 12 is bent so that a midway portion thereof protrudes rearward, and is formed in a substantially “h” shape or an arc shape in a side view, and is arranged so that the front end portion 12a faces the advancing direction of the machine body. In other words, the lower portion of the guide rod 12 is curved so as to swell rearward in a side view, and the front lower end is configured to face obliquely downward and forward, and substantially in the front and rear middle portion or rear portion of the focusing rod 11 in a side view. It arrange | positions so that it may cross | intersect X shape. In this way, as much waste as possible can be collected by the focusing rod 11 and the guide rod 12, and as much waste as possible can be collected in as little space as possible.
On the other hand, the converging rod 11 protrudes rearward and downward, is bent in the middle thereof to be formed in an arc shape (or a crank shape), and the tip end portion 11a is disposed so as to face substantially downward. .
The conventional focusing rods are projected substantially horizontally in the rear and the guide rods are linear. Therefore, when the amount of focusing of the drainage is increased, it accumulates upward, and its center of gravity is also upward. Then, since the center of gravity is low and the light is focused in a substantially circular shape in cross section, the cross sectional area can be made smaller than in the past.

As shown in FIG. 1, in the closed state, the angle θ1 formed by the rear end of the focusing rod 11 with the horizontal plane is set to be substantially perpendicular, and the angle formed between the tip 12a of the guide rod 12 and the horizontal plane is θ2. Then, the angle θ2 is set so as to be an acute angle that falls forward. In the closed state, the focusing rod 11 and the guide rod 12 intersect with each other when viewed from the side, and the exhaust rod is focused in that state.
The shaft 21 is provided so that the arm 23 can rotate integrally so that the arm 23 protrudes forward, and when the arm 23 is rotated, the rotating arm 22 on the shaft 21 is also rotated simultaneously. It is configured.

  The driving means 13 is supported on the lower side of the support frame 15 so as to be positioned between the focusing rod 11 and the guide rod 12. The driving means 13 links an electric motor 31 that is an actuator, a rotating plate 32 that is rotatably provided on an output shaft 31 a of the electric motor 31, and an arm 18 that is fixed to the rotating plate 32 and the shaft 16. The linkage link 33, the linkage link 34 that links the rotary plate 32 and the arm 23 fixed to the shaft 21 and the like, and the focusing rod 11 and the guide rod 12 can be rotated by driving the electric motor 31, respectively. It is configured to be able to. As for the rotation stroke of the focusing rod 11 and the guide rod 12 rotated by the driving means 13, the arm 18 and the arm are arranged so that the rotation angle of the guiding rod 12 is smaller than the rotation angle of the focusing rod 11. 23 and the linkage positions of the linkage links 33 and 34 are set.

  In such a driving means 13, when the electric motor 31 is driven and the rotating plate 32 is rotated in the X1 direction in FIG. 1, the linkage links 33 and 34 are cranked so that the arms 18 and 23 are respectively connected to the shafts 16 and 16. Rotating downward about 21, the focusing rod 11 is rotated forward and downward as one arm 18 is rotated, and the guide rod 12 is moved rearward and upward as the other arm 23 is rotated. It is rotated. Then, the focusing rod 11 and the guide rod 12 are rotated by a predetermined rotation stroke in a direction away from each other, and the tip of the focusing rod 11 is in the “open” position (discharge position) as shown in FIG. Is directed substantially downward in the vertical direction, and the front end portion 12a of the guide rod 12 is directed obliquely forward and downward (aircraft traveling direction).

  In this way, the focusing rod 11 and the guide rod 12 are forcibly driven, the waste rod placed on the focusing rod 11 falls downward, and the waste rod placed on the guide rod 12 is dropped obliquely forward, The waste will be dropped in the form of a lump, and even if the harvest amount increases, there is a definite boundary between the waste that has converged and the waste that has fallen before it. Can be separated. On the other hand, in the conventional focusing device, most of the eaves are placed on the eaves and rotated downward against the spring force. As a result, the sluice slips downward and slanted downward, and the guide stub is just an action that pivots backward and opens the opening. , There was a situation where there was no boundary.

  On the contrary, when the electric motor 31 is driven and the rotating plate 32 is rotated in the X2 direction in FIG. 2, the arms 18 and 23 are rotated upward about the shafts 16 and 21 by the link links 33 and 34, respectively. Then, the focusing rod 11 is rotated upward with the rotation of one arm 18, is rotated so as to receive the falling waste rod, and the guide rod 12 is rotated with the rotation of the other arm 23. Is rotated downward so as to cut off the flow of falling waste. In other words, in the present invention, both the focusing rod 11 and the guide rod 12 are driven to open and close, and are closed at the front and rear approximate center positions of the waste collecting device 10, so that it is opened compared to the conventional configuration of closing at the rear end. The time taken to close and the time taken to close can also be shortened, and even if a large amount of scuttle is dropped, even if a large amount of sewage is dropped, the length between the lumps of fallen waste can be lengthened by the shortened amount. It can be done. However, one end of the linkage links 33 and 34 is pivotally supported on the same axis and is supported by the rotating plate 32 or the crank arm so that the electric motor 31 is rotated in the same direction without being reversed. You can also.

  Further, in the closed state as shown in FIG. 1, the rear portion of the focusing rod 11 is curved so as to protrude rearward, and the tip portion 11a is directed vertically downward to form a substantially vertical surface. Yes. The guide rod 12 intersects with the inclined surface immediately before becoming a vertical surface, and the waste is accumulated in a space surrounded by the focusing rod 11 and the guide rod 12.

Next, using FIG.5 and FIG.6, a mode until the exclusion focusing apparatus 10 transfers to a closed state again from a closed state is shown. 5 and 6, (a) is a closed state in which the waste is stored, (b) is a state in which the closed state is shifted to an open state, (c) is an open state, and (d) is an open state. (E) shows the closed state after discharging the waste, respectively.
As shown in FIG. 5, when the focusing rod 11 is configured in a straight line, when the discharge speed (the number of revolutions) is increased, the discharging rod accumulated on the focusing rod 11 at the time of discharging is closed before it completely falls. In order to make a transition, as shown in FIG. 5 (e), a part of the slag remains and drops without interruption, and the slag remaining at the tip of the focusing squirrel 11 is thrown rearward and converged. There was a case where it was disturbed. In order to solve this problem, if the focusing rod 11 is shortened, the focusing width (falling width in the forward direction) is widened, so that the drainage droops at low speed and the boundary may be lost.

  Therefore, as described above, the middle portion of the focusing rod 11 is curved so as to protrude rearward in a side view, so that in the closed state, it is divided by the curved portion of the focusing rod 11 and the portion where the guide rod 12 intersects. Waste is deposited in the space. When the guide rod 12 moves to the discharge position and is in the open state, as shown in FIG. 6 (e), the waste deposited on the focusing rod 11 does not fall diagonally backward, but is perpendicular to the tip portion 11a. Since it falls almost vertically downward along the surface, it is possible to prevent scattering and unfocusing. Even immediately before closing, the tip 11a of the focusing rod 11 faces downward, so there is almost no residue remaining on the focusing rod 11, and the tip 11a of the focusing rod 11 is not blown away.

  As shown in FIG. 3, the electric motor 31 of the driving means 13 is connected to a control device 35 and is controlled by the control device 35. The control device 35 is provided at an arbitrary position of the machine body, and is connected to an open / close detection sensor 41 that is a means for detecting the open / closed state of the evacuation focusing device 10 based on the rotation amount of the output shaft 31a of the electric motor 31. Based on the detection value of the detection sensor 41, the open / close state of the rejection focusing device 10 can be determined.

  The control device 35 is connected to a threshing clutch sensor 36 which is a means for detecting the disengagement state of the threshing clutch and a waste amount sensor 37 which is a means for detecting the amount of waste transported by the waste transporting device 2. Based on the detected values of 36 and 37, the open / close state of the rejection focusing apparatus 10 is controlled. That is, when the control device 35 detects that the threshing clutch is disconnected by the threshing clutch sensor 36 or the waste amount sensor 37 detects that the waste is not being transported by the waste transporting device 2, The driving of the electric motor 31 is stopped only for a certain period of time, so that the evacuation focusing apparatus 10 is held in the closed state.

  The control device 35 is also connected to a rotation speed sensor 38 which is means for detecting the rotation speed of the drive shaft of the feed chain, and compares the detected value of the rotation speed sensor 38 with a preset set value. As a result, the drive interval of the electric motor 31 is adjusted as appropriate to control the open / close state of the rejection focusing device 10. That is, the control device 35 drives the electric motor 31 in synchronization with the drive of the feed chain, so that as the rotation speed of the drive shaft of the feed chain increases, the control apparatus 35 discharges in proportion to the rotation speed or stepwise. The time for stopping the eyelid focusing device 10 in the open state and the time for stopping it in the closed state are lengthened so that a large amount of waste can be discharged. On the contrary, when the amount of cutting is reduced and the rotational speed of the drive shaft of the feed chain is reduced, the time for stopping the rejection focusing apparatus 10 in the open state and the time for stopping in the closed state are shortened. In this way, the amount of waste collected in the closed state of the waste collection device 10 is set to a substantially constant amount.

  The control device 35 controls the open / close state of the waste condensing device 10 based on the detection value of the waste amount sensor 37 provided in the waste transporting device 2 instead of the rotation speed sensor 38, and similarly the waste condensing device. It is also possible to configure so that the focusing amount of the waste in the 10 closed state is maintained at a substantially constant amount. In this case, when the amount of waste transported by the waste transporting device 2 increases, the control device 35 shortens the drive interval of the electric motor 31 and sets the open and closed states of the waste focusing device 10. While reducing the time, when the amount of waste transported by the waste transporting device 2 decreases, the drive interval of the electric motor 31 is lengthened so that the open state and the closed state of the waste focusing device 10 are lengthened. Composed.

The waste amount sensor 37 is a device that measures the amount of vertical movement of the jaw 4 disposed below the waste transport chain 3 of the waste transport device 2. Specifically, the displacement amount sensor 37 is configured by a linear potentiometer or the like, and measures the position of the jaw 4 that moves up and down depending on the amount of displacement and transmits the data to the control device 35. Based on the data sent to the control device 35, the opening / closing time of the rejection focusing device 10 is set. However, the means for detecting the amount of waste can be arranged in a feed chain, a vertical transport device or the like instead of being arranged in the waste conveying device 2, and instead of detecting the amount of movement of the pinching It is also possible to adopt a configuration in which the amount of wrinkles is detected by bringing the contact detection member into direct contact with the conveyed wrinkles.
Further, the waste amount sensor 37 can be constituted by a sensor that senses the weight of the waste. In this case, the weight of the waste placed on the focusing rod 11 is detected, the amount of waste is measured, and the data is transmitted to the control device. Even if the amount of cereals to be harvested has changed, such as when one or two reapers are harvested by harvesting a deformed field or by combining three slivers by detecting the amount of cocoons conveyed in this way, Since it can be discharged in a concentrated manner according to the amount of cereals, the variation in the amount of slag discharged from each lump can be reduced.

In addition, the control device 35 manually changes the drive interval of the electric motor 31 for switching the open / close state of the rejection focusing device 10 using the setting device 39, and arbitrarily adjusts the amount of rejection focusing in the rejection focusing device 10. It is configured to be able to. It should be noted that the amount of waste collected in the waste collection device 10 can be adjusted by the rotational speed of the electric motor 31.
That is, the focusing amount can be made constant by changing the rotation speed of the electric motor 31 in accordance with the setting of the speed of the waste transport chain 3 and the focusing amount of the waste. For example, when the rotational speed of the drive shaft of the waste transport chain 3 detected by the rotational speed sensor 38 becomes 1.5 times, the rotational speed of the electric motor 31 is also made 1.5 times, so that The amount of focusing is constant.
Further, when the focusing amount is set to double by the setting device 39, the focusing amount according to the setting can be collected by setting the speed of the electric motor to one half. Thus, the focusing amount can be stabilized even when the vehicle speed is increased.

  Further, the control device 35 forcibly drives the electric motor 31 and holds the waste collection device 10 in an open state when an operation switch 40 provided at an arbitrary position of the machine body such as a driving operation unit is turned on. It is configured as follows. Accordingly, the waste transported by the waste transporting device 2 can be discharged in a drooping manner without being cut by the waste cutting device 5 and without being focused by the waste transporting device 10. ing.

  By configuring in this way, the evacuation focusing device 10 is closed during the set time set by the control device 35 based on the detection value of the rotation speed sensor 38, and the focusing rod 11, the guide rod 12, Are held at the waste catching positions where they cross each other, and the wastes conveyed from the waste transporting device 2 are received by the focusing rod 11 while being guided by the guide rod 12. Stacked in between and focused. Then, after the set time elapses, the focusing rod 11 and the guide rod 12 are rotated away from each other by the drive of the electric motor 31 of the driving means 13 and held in the waste discharging position, and the waste focusing device 10 is opened. In this state, a predetermined amount of waste from the condensing rod 11 and the guide rod 12 is guided by the converging rod 11 and the guide rod 12, and the predetermined amount of waste discharged earlier on the ground and the predetermined interval. Released with a gap.

  Further, when the set time elapses, the electric motor 31 of the driving means 13 is driven again, and the driving of the electric motor 31 rotates the converging rod 11 and the guide rod 12 so as to approach each other, and rejects the waste. The waste collection device 10 is closed at the position, and the waste collection device 10 again converges the waste from the waste conveyance device 2 by the collection rod 11 and the guide rod 12. Thus, during the harvesting and threshing operation of the combine, the squeezing and discharging of the sewage by the squeezing and focusing device 10 are repeated, and the sewage is arranged on the ground at predetermined intervals as a bundle of a predetermined amount. Become.

  The switching of the open / close state of the squeezing and focusing device 10 is controlled by the control device 35 as follows. That is, as shown in FIG. 4, it is first determined whether or not the threshing clutch is in an OFF state based on the detected value of the threshing clutch sensor 36 (step S1). If the threshing clutch is not in the OFF state, it is determined whether or not the operation switch 40 is in the ON state (step S2). If the operation switch 40 is in the ON state, the threshing clutch is rejected based on the detection value of the open / close detection sensor 41. It is determined whether or not the focusing device 10 is open (step S3). If the rejection focusing device 10 is not in the open state, the electric motor 31 is driven (step S4), the rejection focusing device 10 is in the open state, and conversely if the rejection focusing device 10 is in the open state. Then, the driving of the electric motor 31 is stopped (step S5), a flag indicating the open state is raised (step S6), and the rejection focusing device 10 is held in the open state.

  If the operation switch 40 is not in the on state in step S2, the rotational speed (B) of the feed chain is detected by the rotational speed sensor 38 (step S7), and the feed chain is stopped based on the detected value. It is determined whether or not there is (step S8). When the feed chain is not stopped, the waste amount (A) transported by the waste transport device 2 is detected by the waste amount sensor 37 (step S9), and the waste transport is performed based on the detected value. It is determined whether or not the waste is being conveyed by the device 2 (step S10). When waste is being transported by the waste transporting device 2, the focusing amount set by the setting device 39 is read (step S11), and the time during which the waste focusing device 10 is kept closed (Tclose). Is calculated (step S12).

  When the electric motor 31 for switching the open / close state of the waste condensing device 10 is synchronized with the feed chain, the time (Tclose) for holding the waste condensing device 10 in the closed state is expressed by the following formula (1).

  In order to synchronize with the exclusion amount sensor 37, the formula 2

  Indicated by

  Then, after calculating the time (Tclose) for holding the waste collection device 10 in the closed state, it is determined whether or not a flag indicating the open state of the waste collection device 10 is set (step S13), indicating the open state. If the flag is set, it is determined whether or not the rejection focusing device 10 is in an open state (step S14). If the rejection focusing device 10 is not in the open state, the electric motor 31 is driven (step S15), the rejection focusing device 10 is in the open state, and the retention time (T1) is a constant. Is set to be equal to the time (Topen) for maintaining the open state (Step S16), a flag indicating the open state is set (Step S17), and the rejection focusing apparatus 10 is held in the open state. On the other hand, if the rejection focusing apparatus 10 is in the open state in step S14, the driving of the electric motor 31 is stopped (step S18), and the holding time (T1) is subtracted by a predetermined time (Δt) and calculated again (step S19). It is determined whether the open state holding time (T1) has elapsed (step S20). Then, if the open state holding time (T1) has not elapsed, the rejection focusing apparatus 10 is held in the open state, and if the open state holding time (T1) has elapsed, a flag indicating a closed state is set. (Step S21), the rejection focusing device 10 is closed.

  Further, when the flag indicating the open state of the waste collection device 10 is not set in step S13, it is determined whether or not the waste collection device 10 is closed (step S22). If the rejection focusing device 10 is not closed, the electric motor 31 is driven (step S23), the rejection focusing device 10 is opened, and the retention time (T2) is closed. Is set to be equal to the holding time (Tclose) (step S24), a flag indicating the closed state is raised (step S25), and the rejection focusing apparatus 10 is held in the closed state. On the other hand, if the rejection focusing apparatus 10 is in the closed state in step S22, the drive of the electric motor 31 is stopped (step S26), and the holding time (T2) is subtracted by a predetermined time (Δt) and calculated again (step S27). It is determined whether or not the holding time (T2) has elapsed (step S28). If the holding time (T2) has not elapsed, the evacuation focusing apparatus 10 is held in a closed state, and if the holding time (T2) has elapsed, a flag indicating an open state is set (step S29), The evacuation focusing device 10 is opened.

  In addition, when the threshing clutch is in an off state in step S1, when the feed chain is stopped in step S8, or when the waste is not being transported by the waste transport device 2 in step S10, the waste focusing device. It is determined whether or not 10 is closed (step S30). If the rejection focusing device 10 is not in the closed state, the electric motor 31 is driven (step S31), and the rejection focusing device 10 is in the closed state. Is stopped (step S32), a flag indicating the closed state is raised (step S33), and the waste and focusing device 10 is held in the closed state.

  Further, the driving means for rotating the focusing rod 11 and the guide rod 12 can be configured as driving means 50 and 70 described below. As shown in FIGS. 7 and 8, the drive means 50 includes a drive pulley 52 on a shaft 51 that rotates by obtaining power from a waste cutting device 5 (high speed shaft or low speed shaft) via a belt 49, and driving. A linkage link 56 that links a pulley 52 and an arm 55 fixed to a cam 54 provided on a shaft 53 via a one-way clutch, and a rotating plate 58 provided on a shaft 57 so as to be able to contact the cam 54. And a link 61 that links the rotary plate 58 and the arm 60 on the shaft 59, a rotary plate 63 provided on the shaft 62 so as to be able to contact the cam 54, and the like. The focusing rod 11 provided on the 59 via the arm 64 so as to be integrally rotatable and the guide rod 12 fixed to the rotating plate 63 can be rotated.

  A spring 66 is provided between a support frame 65 that supports the driving means 50 and is attached to the rear portion of the severing and cutting device 5, and a linkage link 61 that is pivotally supported by the rotary plate 58. Thus, the rotating plate 58 is urged so as to come into contact with the outer periphery of the cam 54 at the contact portion 58 a via the linkage link 61. A spring 67 is also provided between the support frame 65 and the rotating plate 63, and the rotating plate 63 is urged by the spring 67 so that the rotating plate 63 comes into contact with the outer periphery of the cam 54 at the contact portion 63 a. .

  With this configuration, when the drive pulley 52 is rotated in FIG. 7, the arm 55 is swung vertically by the crank movement of the linkage link 56, and the cam 54 rotates in one direction via the one-way clutch.

A rotating plate 74 provided on the same axis and rotating integrally, an arm 77 provided on a shaft 75 rotatably supported by the support frame 15 via a one-way clutch 76, and the arm 77 and the rotating plate 74. The linkage link 78 to be linked, the rotation plate 79 provided coaxially with the arm 77 and rotating integrally, and the shaft 80 provided so as to protrude sideways from the rotation plate 79 are fixed. A link 82 that links the arm 81, the arm 81 and the arm 18 fixed to the shaft 16, and a link 83 that links the bearing 83 supported by the shaft 80 and the arm 23 fixed to the shaft 21. 84.

  In this case, when the drive pulley 73 is rotated, the rotating plate 74 is rotated integrally with the drive pulley 73, and the arm 77 on the shaft 75 is swung in the vertical direction by the crank motion of the linkage link 78, via the one-way clutch 76. Thus, the rotation plate 79 is rotated in one direction. Then, the link plates 82 and 83 are cranked by the rotation of the rotation plate 79, and the arms 18 and 23 are rotated about the shafts 16 and 21, respectively. The focusing rod 11 fixed to the shaft 16 via the rotating arm 17 and the guide rod 12 fixed to the shaft 21 via the rotating arm 22 are disposed at the discharge discharge position or the discharge receiving position. It is rotated to become. In this way, the driving means 70 can also rotate the focusing rod 11 and the guide rod 12 to switch the open / close state of the waste collecting device 10 at regular intervals.

  In the driving means 50 and 70, electromagnetic clutches are provided on the shafts 51 and 72 to which the driving pulleys 52 and 73 are fixed, and are connected to the control device. The power transmitted from the waste cutting device 5 to the drive pulleys 52 and 73 may be cut off based on the detection value of the waste amount sensor that detects the amount of soot. Thereby, when the waste is not transported by the waste transporting device 2, the electromagnetic clutch is disengaged, the power transmitted from the waste cutting device 5 to the drive pulleys 52 and 73 is cut off, and the waste focusing device 10 It is also possible to stop the operation. Instead of providing an electromagnetic valve, a belt tension clutch is provided on the belts 49 and 71 wound around the drive pulleys 52 and 73, and the belts 49 and 71 are provided by a tension pulley pivoted on a tension arm of the belt tension clutch. Can be selectively switched between a tension state and a relaxed state, so that the power transmitted from the reject cutting device 5 to the drive pulleys 52 and 73 can be connected and disconnected.

  As described above, the waste collecting apparatus according to the present embodiment includes the focusing rod 11 that receives the waste that is conveyed from the waste conveying device 2, and the focusing rod 11 that is disposed behind the focusing rod 11 to collect the waste. And a driving means for rotating the converging rod 11 and the tip end portion 12a of the guiding rod 12 so as to cross each other, so that the waste is converged and discharged every predetermined amount. The exhaust and focusing device is configured to bend backward from the middle part of the focusing rod 11, and when the focusing rod 11 and the guide rod 12 are in a closed focusing state, the focusing rod 11 The rear end portion 11a is configured to be directed substantially downward in the vertical direction. With this configuration, when the amount of waste per unit time increases, even if the rotation speed of the guide rod and the focusing rod increases, the converged waste is dropped vertically to form the focusing rod. The remaining waste can be eliminated, and each focused waste can be discharged. Moreover, since the waste is less likely to disperse than when it is discharged obliquely downward, it is easy to visually check the boundary between the wastes.

  A means for measuring the amount of waste conveyed from the waste transporting device 2 is disposed in the waste transporting device 2, and the waste amount measuring means and the driving means 2 are connected to the control means 35, The focusing rod 11 and the guide rod 12 are configured to open and close in accordance with the amount of the rod.
