Description

  The present invention relates to a loading platform in a dump truck for transporting grains, which is used to load and transport the grains in a loading platform that rotates the dump dump.

  In the field, the grains harvested from the napped rice by the combine are ginger with a lot of moisture, so it is necessary to quickly dry them. For this reason, the straw harvested by the combine in the field is usually taken out from the grain tank equipped on the combine body and loaded onto the dump truck platform waiting on the farm road in the field. It is transported to a drying treatment plant, such as a grain processing facility where a grain dryer is installed, where it is discharged from the loading platform by turning the loading platform dumper, and placed in the hopper of the relay transfer machine prepared at that processing plant. It is supplied and supplied to the body of the grain dryer installed in the drying treatment plant by the operation of the relay transporter, and is subjected to the drying process by the grain dryer.

  Thus, in order to dry-process the ginger harvested by the combine, the dump truck for transporting the grain used to transport the straw from the field to a drying processing plant such as a facility where a grain dryer is installed, Basically, when the loading platform dumps and pivots, the rear platform of the loading platform rotates and opens, so that an opening formed by the rear edge of the floor plate of the loading platform and the rear edges of the left and right side plates of the loading platform (release It is only necessary that the outlet is opened, and the opened opening is used as a discharge port, and the soot particles loaded in the bed are discharged from the discharge port due to the inclination of the bed due to the dump rotation. Is.

  However, the dump truck used for transporting this kite, by turning the rear kite of the loading platform, throws the kite that flows out from the discharge port formed at the rear edge of the loading platform into the hopper of the relay conveyance machine and allows it to be inherited. Therefore, a discharge port composed of an opening formed by the rear end edge of the floor plate of the cargo bed and the rear end edges of the left and right side fences, and the reception of the relay transporter that receives the firewood discharged from the discharge opening. There are restrictions on the configuration in relation to the upper mouth of the hopper serving as the entrance.

  In the dump truck, the height of the ground on the lower surface of the floor plate of the loading platform is configured to be higher than the height of the ground at the top edge of the hopper of the relay transporter, and the relay transporter is placed behind the rear edge of the load carrier Then, when setting the relay transporter to the dump truck's carrier so that the grains released from the outlet at the rear edge of the carrier flow into the hopper of the relay transporter, It is desirable that the lip on the side facing the loading platform of the upper mouth can be in a state of entering below the lower surface of the floor plate of the loading platform.

  Referring to the drawings, FIG. 1 is a longitudinal front view of a conventional relay transfer machine A, FIG. 2 is a view showing a vertical side face of the same relay transfer machine A, and a rear side face of a dump truck B. It is.

  The relay transport machine A includes struts 10 erected at the four corners, struts 10 that are opposed to the front and rear of the struts 10 and a strut 10 that is spanned between the struts 10, and struts 10 that are opposed to the left and right. A main frame 1 that is long in the front-rear direction is assembled with the beam member 12 that is bridged between the columns 10 and a hopper 2 that has a substantially bowl shape in the front-rear direction is mounted inside the main frame 1. A screw auger 3 is mounted at the bottom of the hopper 2 to convey the granules put into the hopper 2 from the rear end side to the front end side of the hopper 2, and the lower peripheral side of the screw auger 3 An opening 31 that opens downward is opened on the front end side of the floor surface of the conveying rod 30 that surrounds the flexible conveying cylinder 40 and a steel wire fitted in the conveying cylinder 40 is spiraled below the opening 31. And a spring wire conveyor (not shown) Assembling and coordinating the proximal end portion 4a of the grain conveyor 4 called so-called Banekon, a receiving opening 41 provided on the upper surface side of the base end portion 4a are constituted by connecting to the opening 31. The grain conveyor 4 receives the grains in the hopper 2 discharged through the opening 31 into the base end 4a, and a motor (not shown) that drives the drive shaft 42 to be mounted on the base end 4a. By rotating the conveyor of the spring wire, the received soot particles are transported toward the front end side of the transport cylinder 40 and opened at the front end portion 4b provided on the front end side of the transport cylinder 40 It is configured to discharge from the outlet 43.

  In this relay carrier A, the main frame 1 and the front-rear length L of the hopper 2 mounted on the main frame 1 have the left and right width dimensions L1 of the loading platform 5 of the dump truck B indicated by chain lines in FIG. Longer than that.

  Then, the rice cakes harvested by the combine in the field, loaded on the loading platform 5 of the dump truck B waiting on the farm road in the field, and transported by the dump truck B to the drying processing field such as the facility are relayed by this relay transport machine A. When the product is discharged into the receiving hopper c of the grain dryer C from the outlet 43 of the grain transporter 4 of the relay transporter A and supplied to the grain dryer C, first, The relay transporter A is in a state in which the discharge port 43 of the grain transporter 4 is connected and communicated with the receiving hopper c of the grain dryer C installed in the drying processing plant such as a facility.

  The relay transporter A has one peripheral wall 20 ′ of the left and right peripheral walls 20 out of the four peripheral walls of the hopper 2 entering the drying treatment plant and moving toward the relay transporter A by reverse travel. It arrange | positions in a drying process place so that the driving | running route of the dump truck B which drive | works may occupy the state position which crosses the traveling route.

  As a result, the dump truck B that has loaded the soot grains on the loading platform 5 and entered the drying treatment plant has traveled toward the relay transfer machine A with the rear end of the loading platform 5 as the head by reverse traveling, and the dump truck B As shown in FIG. 2, the rear end of the loading platform 5 passes over the peripheral wall 20 ′ on the side facing the dump truck B on one of the left and right peripheral walls 20 of the hopper 2 of the relay transporter A. When the upper side of the upper opening 2a of the hopper 2 is faced above, the backward traveling of the dump truck B is stopped, the dump truck B is fixed at the state position, and from this state, the loading platform 5 is dumped and rotated. When the soot particles loaded and transported in the cargo bed 5 are caused to flow out from the discharge port 50 at the rear edge of the cargo bed 5 which is opened by the opening rotation of the rear lid 51, the soot particles that flow out. Is indicated by a double-lined arrow in FIG. Sea urchin, flows into the hopper 2 of the intermediary conveyance apparatus A, and to be passed on to the intermediary conveyance apparatus A.

  By the way, in this way, the relay work of the kite that is performed by combining the rear end portion of the loading platform 5 of the dump truck B and the hopper 2 of the relay transporter A has a ground height H on the lower surface of the floor board 5a of the loading platform 5 of the dump truck B. It is assumed that the height of the upper edge of the left and right peripheral walls 20 of the hopper 2 of the relay transporter A is higher than the ground height h.

  When the dump truck B is configured such that the height H of the lower surface of the floor plate 5a of the loading platform 5 is lower than the ground height h of the upper edge of the peripheral wall 20 of the hopper 2 of the relay transporter A, It becomes difficult to transfer the soot particles flowing out from the discharge port 50 at the rear end edge of the loading platform 5 into the hopper 2 of the relay transporter A by the dumping rotation of the loading platform 5 of the dump truck B.

  In other words, in the above-described case, one of the peripheral walls of the left and right peripheral walls 20 of the right and left peripheral walls 20 of the hopper 2 of the relay transporter A faces the rear end of the load carrier 5 due to the backward traveling of the dump truck B. When it moves backward until it reaches the upper end edge of 20 ', as shown in FIG. 4, it abuts against and contacts the outer surface of the one peripheral wall 20' of the hopper 2, and the hopper 2 and The main frame 1 on which the hopper 2 is mounted is pushed out in the moving direction of the loading platform 5 and the relay transfer machine A is turned over. For this reason, the backward traveling of the dump truck B is stopped when the rear end portion of the loading platform 5 comes into contact with the outer surface of the one peripheral wall 20 ′ of the hopper 2, and the dump truck B is fixed in the state position, 4, the hopper 2 of the relay transporter A is located adjacent to the rear end of the loading platform 5 of the dump truck B as shown in FIG. It is forced to cause the soot to flow out from the discharge port 50 at the rear end of the loading platform 5, to flow into the hopper 2, and to be inherited.

  In this case, since the outer surface of the upper edge of the one peripheral wall 20 ′ of the hopper 2 is adjacent to the rear edge of the loading platform 5, the discharge opening that is opened by rotating the loading platform 5 by dumping. Since the position of the rear end edge of the floor plate 5a, which is the discharge position for substantially discharging 50 soot, is positioned above the upper end edge of the peripheral wall 20 ', the soot flowing out from the discharge port 50 However, when it flows into the hopper 2, as shown by an arrow “a” in FIG. 5, a lot of wrinkles that escape to the outside of the hopper 2 are generated, and accurate inheritance cannot be performed.

  As a countermeasure, the relay transporter A forms the peripheral wall 20 ′ on the side facing the rear end of the loading platform 5 of the dump truck B out of the left and right peripheral walls 20 of the hopper 2 with a flexible sheet S or cloth. When the dump truck B is configured to be deformable and configured so that the height of the ground surface of the floor 5a of the loading platform 5 is lower than the height of the relay carrier A, the relay As shown in FIG. 4, the transporter A holds the airframe in a state adjacent to the rear end edge of the loading platform 5 of the dump truck B and can be deformed by the flexible sheet S or the cloth. As shown in FIG. 6, the constructed peripheral wall 20 ′ is deformed so that the upper end edge is brought into contact with the rear surface of the floor plate 5a of the loading platform 5 and is made of a locking member provided on the upper end edge of the peripheral wall 20 ′. Means, or a rubber cord attached to the upper edge of the peripheral wall 20 ' The upper end edge of the peripheral wall 20 'is engaged or fastened to the rear surface of the floor plate 5a of the cargo bed 5 by fastening means made of a material, and as shown in FIG. 6, the rear edge of the cargo bed 5 Attempts have been made to surround the lower part of the discharge port 50 formed in the section with the peripheral wall 20 ′ and prevent the soot flowing out from the discharge port 50 from escaping out of the hopper 2.

  However, this means is made of a flexible sheet S or cloth when the dump truck B is moved out of the facility or the like after the loading of the bag from the loading platform 5 of the dump truck B into the hopper 2 of the relay transporter A is completed. Forgetting to release the engagement or fastening between the upper edge of the peripheral wall 20 ′ and the lower surface of the floor plate 5 a of the loading platform 5, or if the release is incomplete, the loading platform 5 of the dump truck B leaving The peripheral wall 20 ′ formed of the flexible sheet S or the fabric is dragged, thereby causing a problem of causing the relay transporter A to fall.

  In the present invention, as described above, the dump truck B has the ground height H of the lower surface of the floor plate 5a of the loading platform 5 lower than the ground height h of the upper edge of the peripheral wall 20 of the hopper 2 of the relay transporter A. The relay carrier A is arranged behind the rear end portion of the loading platform 5 of the dump truck B, and the particles discharged from the rear end edge of the floor plate 5a of the loading platform 5 are disposed in the hopper 2. When the relay carrier A is combined with the loading platform 5 of the dump truck B so as to be accepted, the relay transportation machine A can only be brought close until the hopper 2 thereof abuts the rear end of the loading platform 5 of the dump truck B. In order to solve the problem of the inheritance of the kite that occurs in the dump truck B, the height of the bottom surface of the floor plate 5a of the loading platform 5 of the dump truck B is low, and below the lower surface of the floor plate 5a of the loading platform 5, Inserting the hopper 2 of the relay transporter A Even when it is not possible, the hopper 2 of the relay transporter A is an invention that aims to provide means for properly receiving the soot discharged from the discharge port 50 at the rear end edge of the loading platform 5 of the dump truck B. .

In the present invention, as means for solving the above-described problem, the rear end of the loading platform 5 of the dump truck B extends rearward from the rear end of the floor plate 5a of the loading platform 5 to extend the floor plate 5a rearward. The floor board F is configured so as to protrude rearward from the rear end of the floor board 5a of the loading platform 5 when the rear lid 51 is rotated rearward and the discharge port 50 on the rear end side of the loading platform 5 is opened. In addition to this, we have raised a dump truck bed for transporting dredging, which is characterized by

  Next, an embodiment of the means of the present invention will be described in detail with reference to the drawings.

  FIG. 7 is a partially longitudinal side view of the rear half of the dump truck bed that implements the means of the present invention, and a longitudinal rear view of the relay carrier used in combination with the dump truck. B is the whole dump truck, 5 is a loading platform of the dump truck B, A is a relay transporter disposed behind the rear end of the loading platform 5 of the dump truck B, and 2 is a hopper of the relay transporting machine.

  In FIG. 7, the dump truck B is omitted from the first half and only the second half is shown, but the engine, power transmission device, hydraulic device, control device, and the like are installed on the first half which is omitted in the drawing. The loading platform 5 is rotated about the fulcrum shaft 60 provided at the rear end portion of the vehicle body b of the dump truck B by the operation of the hydraulic mechanism driven by the engine on the second half side to perform the dumping operation. It is a normal dump truck with a mounted structure.

  The loading platform 5 mounted on the rear half of the vehicle body b includes a floor plate 5a formed in a base plate shape, left and right side bars 52 provided on the left and right side edges of the floor plate 5a, and a front edge of the floor plate 5a. And a rear bar 51 provided at the rear edge of the floor plate 5a, and the rear bar 51 of the loading platform 5 has left and right ends thereof. The support arm 51a provided at the upper end of each of the support members is provided in a protruding manner on the upper surface of the rear end of each of the left and right side bars 52, 52 fixed to the floor plate 5a. Further, when the loading platform 5 is in a horizontal state, the rear rod 51 is connected to the rear edge of the left and right side rods 52 and 52 and the rear edge of the floor plate 5a. Occupies the position where the open port 50 behind the formed flat box-shaped cargo bed 5 is closed, and the cargo bed 5 is dumped backward. When this occurs, the weight of the rear lid 51 itself turns back to the center of the connecting shaft 54 to open the above-described opening, and the granules in the loading platform 5 are discharged using this opening as the discharge port 50. It is like that.

  And the discharge | release of the soot particle from the discharge port 50 at this time is performed in this position by making the rear-end edge of the floor board 5a into a substantial discharge position. Thus, between the lower end portion of the rear cage 51 and the rear end portion of the floor board 5a, as shown in FIGS. 8 and 9, when the loading platform 5 is in a horizontal posture, it is provided at the lower end of the rear cage 51. When the engaging portion 51b engages with the engaging portion 51b to hold the rear rod 51 in the closed position and the loading platform 5 is dumped, the engagement is released and the rear rod 51 is freely rotated around the connecting shaft 54. Locking means 7 for moving is provided.

It is configured by providing a spring 73 that urges the abutting portion 72 so as to hold the abutting portion 72 in a state of abutting against the support portion 71. As a result, when the loading platform 5 is in a horizontal posture, the rotation lever 7a is held in a substantially horizontal posture, so that the rear end locking portion 70 is engaged with the lower end of the rear lid 51 in the closed position. When the rear lid 51 is held in the closed position by being held at the position engaged with the joint portion 51b, and when the loading platform 5 is rotated by dumping, the fulcrum p rises together with the floor plate 5a, so that the rotation lever 7a pivots upward with the abutting part 72 abutting against the support part 71 as a pivotal fulcrum, so that the locking part 70 provided at the rear end rises and separates upward from the engaging part 51b, The rear hook 51 is configured to freely rotate about the connecting shaft 54 in a state in which the engagement is released.

  However, this dump truck B is a relay transport used in combination when the straw harvested by the combine is used for the work of transporting the straw for supplying to the grain dryer installed in the drying processing facility such as the facility. In relation to the machine A, the ground height H of the lower surface of the floor 5a of the loading platform 5 is set lower than the ground height h of the upper edge of the left and right peripheral walls 20 of the hopper 2 of the relay transport machine A. Yes.

  The relay carrier A, like the relay carrier A shown in FIG. 1 and FIG. 2, has four struts 10 erected at the four corners, and the struts 10 and struts of the struts 10 facing each other in the front-rear direction. A main frame 1 that is long in the front-rear direction is assembled with a beam member 11 that can be bridged between the beam 10 and a beam member 12 that is bridged between the column 10 and the column 10 that oppose to the left and right. The left and right bottom walls 21, 21 inclined toward the left and right center parts, the left and right peripheral walls 20, 20 rising from the outer ends of the bottom walls 21, 21, and the front and rear peripheral walls 22, 22, A hopper 2 assembled so as to have a substantially bowl-like shape when viewed from the direction is mounted, and the granules put into the hopper 2 are conveyed from the front end side toward the rear end side at the bottom of the hopper 2. The screw auger 3 is pivoted, and the illustration is omitted in FIG. 7 below the bottom of the hopper 2. However, a base end portion 4a of a grain transporter 4 called a so-called spring con, which is constructed by inserting and configuring a spring conveyor in which a steel wire is formed in a spiral shape, is assembled inside the flexible transport cylinder 40, and the base end portion 4a. A receiving port 41 provided on the upper surface side of the screw auger 3 is positioned on the terminal end side in the conveying direction of the screw auger 3 and is connected to an opening 31 formed in the bottom wall of the hopper 2. The cocoon discharged from 50 is received in the hopper 2, the received cocoon is conveyed to the front end side by the screw auger 3, discharged from the opening 31, and the cocoon discharged from the opening 31 is transferred to the grain conveyor 4. The discharge port 4 provided in the distal end portion 4b is transported toward the distal end side of the transport barrel 40 by the transport barrel 40 that extends into the proximal end portion 4a and extends from the proximal end portion 4a and the spring conveyor in the transport barrel 40. For that is arranged to discharge from are those not different between normal relay conveyor.

  However, in this relay transporter A, the dump truck B that transports the granules inherited to the hopper 2 has the height H of the bottom surface of the floor surface 5a of the loading platform 5 with respect to the ground height H of the normal relay transporter A. The hopper 2 is configured on the assumption that it is configured to be lower than the ground height h at the upper edge of the left and right peripheral walls 20, 20.

  That is, when the dump truck B moves backward toward the peripheral wall of the hopper 2 of the relay transporter A by the backward traveling, the rear end of the cargo bed 5 is brought to the outer surface of the peripheral wall of the hopper 2. As a countermeasure against such a situation, the peripheral wall 20 on the side facing the rear end of the loading platform 5 of the dump truck B out of the left and right peripheral walls 20 and 20 of the hopper 2 is planned. 'Is formed by a flexible sheet S or fabric so that it can be bent and deformed, and the lower edge side is joined and connected to the end edge portion of the bottom wall 21 of the hopper 2, and the upper edge side is along the upper edge portion. The attached rubber string or rope (not shown) is stretched between the front and rear peripheral walls 22 of the hopper 2 so as to be held in a predetermined state position, and as described above, the rear end of the loading platform 5 has the peripheral wall 20. When it comes into contact with the outer surface of the upper end of ' The tension such as the loop is relaxed, and the peripheral wall 20 ′ made of the flexible sheet S is deformed, thereby bringing the rear end portion of the loading platform 5 closer to the relay transporter A as shown in FIG. The upper end edge of the deformed peripheral wall 20 ′ is brought into contact with the rear surface of the rear end of the floor plate 5a of the loading platform 5, and a locking piece (not shown) attached to the upper edge of the peripheral wall 20 ′ is provided on the floor plate. The upper edge of the peripheral wall 20 ′ is adhered to the rear surface of the rear end portion of the floor plate 5 a by engaging with a protrusion provided on the rear end surface of 5 a or tensioning the rubber cord or rope. As a result, the lower part of the discharge port 50 at the rear end of the loading platform 5 opened by the opening rotation of the rear cage 51 of the loading platform 5 is surrounded by the peripheral wall 20 'as shown in FIG.

  Referring again to FIG. 7, F is an extension floor plate that is assembled and installed at the rear end portion of the loading platform 5 so that the floor plate 5 a of the loading platform 5 extends backward, and P is an assembly of the extension floor plate F to the floor plate 5 a of the loading platform 5. The assembly board for this is shown.

  The extension seat plate F dumps the loading platform 5 to incline the floor plate 5a of the loading platform 5 backward, and opens and rotates the rear lid 51 pivotally supported on the rear end portion of the loading platform 5 to open the loading platform 5. 5, the opening 50 at the rear end of the cargo bed 5 formed by the rear edge of the left and right side rails 52 and the rear edge of the floor board 5a is opened, and the cargo opening 5 When discharging the soot particles loaded in the rear of the loading platform 5, the opening position of the discharge port 50, which is the discharge position for substantially discharging the soot particles, is defined as the rear end of the loading platform 5. It is for displacing and moving backward from the rear surface of the part.
