Description

  The present invention relates to a self-propelled screen that sorts recycled raw materials such as crushed stone, wood chips, earth and sand, etc., and recycled products produced from these, according to the particle size.

  In recent years, demand for recycled product production machines that produce recycled products from various recycled raw materials represented by construction-generated soil, rocks, waste tires, and the like, such as soil improvement machines, crushers, and shredders, has increased. As one of the machines that assist the work of these recycled product production machines, for example, recycled materials supplied to the recycled product production machines and recycled products discharged from the recycled product production machines are used as the items to be sorted. There is a self-propelled screen which sorts according to particle size with an apparatus (screen), and conveys the sorted matter that has passed through the sieve device by a discharge conveyor (see, for example, Patent Documents 1 and 2).

JP 2002-4333 A JP 2000-229266 A

  Here, since the sort discharged from the self-propelled screen is accumulated in a predetermined place or is put into various recycled product production machines that can be arranged in the subsequent stage, the sort discharge efficiency In order to ensure the input property to other machines, the discharge height of the discharge conveyor is preferably as high as possible.

  In the self-propelled screen of Patent Document 1, in order to enable self-running, a sieve device is arranged on one side in the longitudinal direction of the main body frame provided on the traveling body, and a power device is arranged on the other side in the longitudinal direction of the main body frame. It is. However, in such a configuration, since the discharge conveyor extends from the lower position of the sieving device to the other side in the longitudinal direction of the main body frame through the lower side of the power device, the presence of the power device located above is present. This contributes to restricting the discharge height of the discharge conveyor. On the other hand, in the technique described in Patent Document 2, since the power unit is disposed below the discharge conveyor, it is advantageous in terms of increasing the discharge height.

  However, the inclination angle of the discharge conveyor must be a value within a range in which the sorted product to be transported does not slide down. Normally, the inclined angle is naturally limited by the frictional force between the sorted product to be conveyed and the conveyor belt. The angle is limited to a certain degree (for example, about 20 °). For this reason, when the discharge conveyor is provided above the power unit, the arrangement position of the discharge conveyor is parallelly moved upward, and as a result of the rise of the center of gravity, the stability of the machine body may be deteriorated. As described in Patent Document 2, if a large traveling body is adopted with respect to the size of the aircraft, the problem of stability can be solved, but the overall height of the aircraft increases, and depending on the size of the aircraft, on public roads It is extremely disadvantageous in clearing the transportation limit height.

  The present invention has been made in view of the above-described matters, and an object thereof is to provide a self-propelled screen that is compact and has a low center of gravity, excellent transportability, and yet can secure a sufficient discharge height. It is in.

  In order to achieve the above object, a first invention includes a main body frame, a sieve device provided on an upper portion on one side in the longitudinal direction of the main body frame, and a power device provided on an upper portion on the other side in the longitudinal direction of the main body frame. And a discharge conveyor disposed so as to be inclined upward from the lower position of the sieving device toward the other side in the longitudinal direction of the main body frame through the upper portion of the power device, and the substantially central direction of the main body frame in the longitudinal direction. And traveling means provided at a lower portion of the position, the longitudinal dimension of which is smaller than the longitudinal dimension of the main body frame.

  According to a second aspect of the present invention, there is provided a travel means, a main body frame provided on the travel means and formed such that both end portions in the longitudinal direction project forward and backward with respect to the travel means, and a longitudinal side of the main body frame. A sieving device provided at the upper part, a power unit provided at the upper part on the other side in the longitudinal direction of the main body frame, and from the lower position of the sieving device to the upper side of the power unit, outward in the longitudinal direction of the main body frame. And a discharge conveyor disposed so as to be inclined upward.

  According to a third invention, in the first or second invention, a side conveyor is provided on one side in the longitudinal direction of the main body frame for transporting a sorting product having a size equal to or greater than the sorting particle size sorted by the sorting device and discharging it outside the machine. The discharge conveyor is disposed at a position shifted to one side from the center in the width direction of the main body frame, and the side conveyor is formed on the other side in the width direction of the main body frame created by shifting the discharge conveyor. It can be accommodated in a space.

  In a fourth aspect based on the third aspect, the side conveyor includes an upstream portion attached to one side in the longitudinal direction of the main body frame and a downstream portion rotatably connected to the upstream portion. The downstream portion is rotated with respect to the upstream portion to be linear, and the upstream portion of the straight side conveyor is rotated with respect to the main body frame so as to be horizontal. It can be developed.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, a supply unit that receives the selected item and supplies it to the sieving device is provided at an upper position on the other side in the longitudinal direction of the main body frame of the sieving device. It is characterized by that.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the magnetic foreign matter from the sorted matter on the discharge conveyor is located on the other side in the longitudinal direction of the main body frame of the sieving device and above the discharge conveyor. The magnetic separator which removes is provided.

  A seventh invention is characterized in that, in any one of the first to sixth inventions, a crushing device for crushing a selection on the discharge conveyor is provided at a position on the discharge conveyor.

  An eighth invention is characterized in that, in any one of the first to seventh inventions, the discharge conveyor is provided with a detecting means for detecting a transport amount of the selected item on the discharge conveyor.

  A ninth invention is characterized in that in any one of the first to eighth inventions, a sieve angle adjusting means for adjusting an inclination angle of the sieve device is provided.

  According to the present invention, the discharge height of the selected item can be sufficiently increased by arranging the discharge conveyor through the upper part of the power unit. At this time, since the longitudinal dimension of the traveling means provided at the lower part of the central position in the longitudinal direction of the main body frame is made smaller than the longitudinal dimension of the main body frame, both longitudinal ends of the main body frame are the traveling body. It will be shaped to project back and forth. And, by providing a power unit on the other side in the longitudinal direction of the main body frame that protrudes forward with respect to the traveling means, a space is created between the power unit and the discharge conveyor, so only the height of this space The center of gravity of the machine can be lowered by shifting the discharge conveyor downward. As a result, it is advantageous for clearing the restricted transport height on public roads and ensuring excellent transportability, and it is possible to ensure sufficient stability while improving the discharge height. On the other hand, by providing a sieving device on one side in the longitudinal direction of the main body frame that protrudes rearward with respect to the traveling means, the weight of the entire body can be sufficiently balanced, so the traveling means can be reduced in size. This also makes it possible to reduce the center of gravity of the aircraft and to make it compact.

When the side conveyor 60 is unfolded from the accommodated state of FIG. 7A, first, the hydraulic cylinder 76 is extended, and the downstream portion 66 of the side conveyor 60 is changed to the upstream portion 65 as shown in FIG. 7B. The downstream portion 66 is rotated so as to be substantially linear. Next, the hydraulic cylinder 69 is contracted, and as shown in FIG. 7C, the side conveyor 60 is rotated about one side in the width direction as a fulcrum to be in a horizontal state. In this state, the hydraulic cylinder 76 is further extended, and as shown in FIG. 7 (d), the side conveyor 60 is rotated with respect to the base 67 so as to be inclined upward toward the downstream side, and is brought into an operating state.

  Further, as described above, the side conveyor 60 is supported by the turning frame 63. Since the turning frame 63 can turn with respect to the base frame 59, the side conveyor 60 can be turned by turning the turning frame 63.

FIG. 10 is an explanatory diagram showing the turning procedure of the side conveyor 60.
FIG. 10A shows the same state as FIG. 7C. When turning the side conveyor 60, first, the hydraulic cylinder 61 is extended, and as shown in FIG. 10B, the base frame 59 is slid in a direction protruding from the mounting frame 9, and the side conveyor 60 is moved.

When the base frame 59 is protruded, the operator pushes the side conveyor 60 to rotate the turning frame 63 (see FIG. 1 and the like) around the rotation shaft 62 (see FIG. 1 and the like), as shown in FIG. In addition, the side conveyor 60 is turned so as to face in the opposite direction to FIG. At this time, a turning device that rotationally drives the rotating shaft 62 may be separately provided, and may be turned hydraulically or electrically without human intervention. When the procedure so far is completed, the hydraulic cylinder 61 is contracted and the base frame 59 is slid to the mounting frame 9 side, and the side conveyor 60 is slid to the operating position as shown in FIG. When operating the side conveyor 60 in this state, the procedure described in FIG. When returning the side conveyor 60 to the state of FIG. 10A again, the procedure reverse to the above is performed.

Next, the operation and action of the self-propelled screen of the present embodiment having the above configuration will be described.
First, as described in FIGS. 7A to 7D, the side conveyor 60 is unfolded and brought into the state shown in FIGS. 8 and 9, and then, for example, the sieve device 15 is sorted by a hydraulic excavator or the like. When the product is put in, the sorted product having a predetermined particle size or less that has passed through the lattice 17 of the sieving device 15 is introduced into the lower hopper 21. Sorted materials received by the hopper 21 are guided onto the discharge conveyor 30, conveyed by the discharge conveyor 30, and discharged outside the apparatus (for example, on the right side in FIG. 8). On the other hand, a selected product having a predetermined particle size or more that does not pass through the lattice 17 of the sieving device 15 moves on the lattice 17 and falls onto the side conveyor 60. And the sorting thing which fell on the side conveyor 60 is conveyed by this side conveyor 60, and is discharged | emitted by the side (in this case, the left side in FIG. 9) of a body.

According to the present embodiment, the discharge conveyor 30 is arranged above the power unit 16 so that the discharge height of the selected item is sufficiently increased as compared with the case where the discharge conveyor 30 is passed below the power unit 12 as in the prior art. be able to.
At this time, since the longitudinal dimension of the traveling body 1 provided at the lower part of the substantially central position in the longitudinal direction of the main body frame 7 is formed smaller than the longitudinal dimension of the main body frame 7, The part protrudes forward and backward with respect to the traveling body 1. And since the both ends of the longitudinal direction of the main body frame 7 project back and forth with respect to the traveling body 1 and the screen device 15 and the power device 16 are mounted on the projecting both ends, the space between the screen device 15 and the power device 16 Sufficient space can be secured. That is, the inclination angle of the discharge conveyor 30 is generally limited to a certain range. However, since the power unit 16 is mounted on the front projecting portion (the other side in the longitudinal direction) of the main body frame 7, the discharge conveyor 30 and the power unit Since a space can be created between the power conveyor 16 and the discharge conveyor 30, the layout of the discharge conveyor 30 can be shifted downward by the height of the space. In comparison, the center of gravity and height of the aircraft can be reduced. As a result, it is advantageous for clearing the restricted transport height on public roads and ensuring excellent transportability, and also ensuring sufficient stability while improving the discharge height.
On the other hand, the weight of the entire fuselage can be balanced by mounting the sieving device 15 on the projecting portion (one side in the longitudinal direction) behind the main body frame 7 by shifting the arrangement of the power unit 16 forward. Since the arrangement height of the sieving device 15 is also reduced, the input property of the object to be sorted is also improved. In addition, since the weight of the entire body can be sufficiently balanced, sufficient stability can be ensured even with a small traveling body. Therefore, the traveling body 1 can be reduced in size, which can also reduce the center of gravity of the vehicle body and reduce the manufacturing cost.

  Moreover, since the downstream part 47 of the discharge conveyor 30 moves up and down with respect to the upstream part 45, the discharge height can be changed step by step from the state shown in FIG. 1 to the state shown in FIG. It is possible to set the discharge height according to. Further, since the downstream portion 47 of the discharge conveyor 30 is moved up and down in this way, as shown in FIG. 11, when the self-propelled screen is transported with a trailer having a smaller capacity, the discharge is also performed. By bending the downstream portion 47 of the conveyor 30 to a substantially horizontal position, the transport height limit H on the public road can be satisfied, and excellent transportability is ensured.

  Moreover, since the space around the discharge conveyor 30 is sufficiently secured by passing the discharge conveyor 30 above the power unit 16, the maintenance of the discharge conveyor 30 can be easily performed, and any foreign matter is discharged. Even when the conveyor 30 is clogged, it is very easy to remove foreign substances.

  By providing the side conveyer 60, it is possible to convey a plurality of sorts having a particle size together with the discharge conveyer 30 to be collected or supplied to other devices. Moreover, since the side conveyor 60 can be folded and accommodated in the side part of an airframe, the transport restrictions at the time of transporting with a trailer etc. can be satisfied. In addition, the side conveyor is usually equipped as an option, and it is generally accompanied by assembly and installation work at the operation site, but in this embodiment, only the hydraulic cylinders are expanded and contracted. Because it can be easily deployed and accommodated without the need for cumbersome assembly and installation work, the side conveyor 60 can be used as a standard equipment and can be immediately transferred to work, improving work efficiency and shortening the work period. Also contributes. And since this side conveyor 60 can be swung, the discharge position of a conveyed product can be changed according to an operation | work, and the layout property in an operation site is also good.

  In addition, since the base frame 59 that supports the side conveyor 60 is configured to be slidable, a work space can be created around (backward) the sieving device 15, so that the maintainability of the sieving device 15 can be improved. it can. Moreover, since the arrangement of the discharge conveyor can be increased as compared with the case where the discharge conveyor is arranged through the lower part of the power unit, it is easy to carry out the work even when maintaining the lower part on the upstream side of the discharge conveyor 30.

  In addition, since it has a traveling body 1 and is configured to be able to travel on its own, it can exhibit sufficient maneuverability in the field and can get on and off the trailer's loading platform by itself. Another major advantage is that no heavy machinery is required.

FIG. 12 is a right side view showing the overall structure of another embodiment of the self-propelled screen of the present invention. In this figure, the same parts as those in the previous figures are denoted by the same reference numerals as those in the previous figures, and the description thereof is omitted.
The present embodiment is an embodiment in which a supply device 90 is provided in the embodiment of the self-propelled screen of the present invention described above to receive a selection and supply it to the sieving device 15.

  In FIG. 12, the supply device 90 includes a chute 91 that receives the selection and guides it to the sieving device 15, and an inclination angle adjusting unit 92 that adjusts the inclination angle of the chute 91.

  The chute 91 is a bottomed saucer-like member that expands upward, and the rear side (left side in FIG. 12) is open, and the chute 91 is discharged on the other side in the longitudinal direction of the main body frame 7 with respect to the sieve device 15. It is provided above the conveyor 30. The rear end of the chute 91 is connected to a support member 93 assembled on the mounting frame 9 via a pin 94, for example, and is configured to be able to rotate in the vertical direction about the pin 94 as a fulcrum.

  On the other hand, the inclination angle adjusting means 92 includes a connecting bar 96 having a plurality of pin holes 95 provided at predetermined intervals in the vertical direction. The connecting bar 96 is connected to the lower portion of the front end of the chute 91 via a pin 97, and is rotatable in the front-rear direction with the pin 97 as a fulcrum. That is, the tilt angle adjusting means 97 tilts the chute 91 to adjust the angle stepwise, and in this state, inserts the pin 99 into the pin hole 95 whose position corresponds to the bracket 98 provided at the front end of the support member 93. Thus, the chute 91 is fixed to the support member 93.

In the present embodiment, when an object to be sorted is introduced into the supply device 90 by an input heavy machine such as a hydraulic excavator, the introduced object to be sorted is guided to the chute 91 and introduced into the sieving device 15. The inclination angle of the chute 91 at this time depends on the sorting object, specifically, the frictional force between the sorting object and the chute 91 so that the sorting object slides on the chute 91 smoothly. Adjust accordingly.
About another structure and operation | movement, it is the same as that of one Embodiment of the self-propelled screen of this invention mentioned above.

  Needless to say, the present embodiment also obtains the same effect as that of the above-described embodiment of the self-propelled screen of the present invention. However, the material to be sorted is once received by the supply device 90 and then introduced into the sieving device 15.
