Description

Technical Field

[0001] The utility model relates to a component of a sugarcane combine harvester, in particular to a cane collecting box capable of being turned over and discharged left and right, belonging to the technical field of agricultural machinery equipment. Background Technique

[0002] A sugarcane combine harvester is an integrated machine that can complete a series of operations such as knocking down sugarcane, dividing rows, cutting the tips, cutting the roots, feeding, conveying, stripping leaves, separating impurities, and collecting sugarcane in a sugarcane field. Generally, a cane collecting box is arranged at the rear end of the sugarcane combine harvester to collect the sugarcane that has been harvested and processed by stripping leaves and removing impurities. Since the sugarcane combine harvester moves back and forth in the sugarcane field and harvests sugarcane row by row during operation, the cane collecting box at its rear end will discharge the cane at the end of the field after the cane is full, so as to quickly empty it to accommodate the next batch of harvested sugarcane.

[0003] At present, most of the cane collecting boxes equipped with sugarcane combine harvesters discharge the cane by opening the bottom plate downward or turning it over backward. In order to ensure that the discharged cane does not affect the harvesting operation of the adjacent rows, it is necessary to drive the sugarcane combine harvester out of the harvesting station and drive it to the harvested row at the end of the field before discharging the cane. After the discharging is completed, it returns to the harvesting station to continue harvesting. However, such an operation will obviously interrupt the continuity of the harvesting work of the sugarcane combine harvester and affect the operation efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cane collecting box capable of being turned over and discharged left and right. The cane collecting box is assembled at the rear end of the sugarcane combine harvester. After the cane is full, the cane can be directly discharged to the side of the harvested row away from the sugarcane harvesting row by tilting it in place. The discharged cane does not affect the harvesting operation, and at the same time, the continuity of the harvesting work of the sugarcane combine harvester can be maintained.

[0005] The specific technical solution of the utility model is as follows:

[0006] A sugarcane collecting box that can be turned left and right for unloading, which comprises two major parts: a base frame and a sugarcane collecting box body; the top surface of the base frame is fixedly connected with more than two guide rails extending horizontally in the left and right directions, and the left and right ends of each guide rail are respectively provided with a U-shaped groove opening upward; the sugarcane collecting box body is a U-shaped cargo compartment surrounded by a base plate and two openable left and right side doors, the two side doors are hinged to the left and right sides of the base plate by hinge joints, and corresponding side door cylinders are respectively provided to control the opening and closing of the two side doors, and the bottom surface of the base plate is fixedly connected with guide grooves extending horizontally in the left and right directions and opening downward, the number and positions of the guide grooves respectively correspond to the number and positions of the guide rails on the top surface of the base frame, and the left and right ends of each guide groove are respectively fixedly connected with a locking shaft; the sugarcane collecting box body is buckled and installed on the base plate through the guide grooves on the bottom surface of the base plate On the guide rails on the top surface of the base frame, the locking shafts at the left and right ends of the guide grooves are respectively placed in the bottom of the U-shaped grooves at the left and right ends of the guide rails. Locking mechanisms are also set up on the left and right ends of the guide rails beside the U-shaped grooves. The locking mechanisms rotatably fix the locking shafts of the guide grooves in the U-shaped grooves of the guide rails. Two unlocking drive devices are also set up in the base frame, and the two unlocking drive devices respectively control the locking mechanisms on the left and right sides to release the locking shafts. A lifting cylinder is set up in the center of the base frame, and the cylinder body of the lifting cylinder is hinged on the corresponding hinge seat of the base frame, and the piston head of the lifting cylinder is hinged to the hinge ears at the center of the left and right positions on the bottom surface of the bottom plate of the sugarcane collecting box. The sugarcane collecting box is also equipped with a control system that can control the actions of the side door cylinder, the unlocking drive device and the lifting cylinder.

[0007] When the sugarcane collecting box needs to be flipped to the left for unloading, the side door on the left is opened by controlling the side door cylinder, and the locking mechanism on the right is controlled by the unlocking drive device to release the locking shaft on the right and keep the locking shaft on the left. When the lifting cylinder is lifted, the sugarcane collecting box can be flipped to the left for unloading with the left lock shaft as the flip hinge axis. When it needs to be flipped to the right for unloading, the operation in the opposite direction can be performed in the same way. Therefore, the sugarcane collecting box can be turned over to the left or right side for unloading as needed. The sugarcane collecting box can be used on a sugarcane combine harvester. During the sugarcane harvesting process, when the sugarcane is full and needs to be unloaded, if the left side of the sugarcane combine harvester is away from the sugarcane harvesting row side, the sugarcane collecting box can be turned over to the left for unloading. If the right side of the sugarcane combine harvester is away from the sugarcane harvesting row side, the sugarcane collecting box can be turned over to the right for unloading. In this way, the sugarcane can be directly unloaded to the harvested row side away from the sugarcane harvesting row on the spot. The unloaded sugarcane will not affect the harvesting operation. At the same time, the sugarcane combine harvester does not need to be moved out of the harvesting station, and the continuity of the harvesting work can be maintained.

[0015] The following further describes the present utility model in conjunction with the accompanying drawings. In the description of the present utility model, the orientation terms of "front", "rear", "left", and "right" are defined based on the perspective of the driver of the sugarcane combine harvester.

[0016] Such as Figure 1-6As shown in the figure, this sugarcane collection box is mainly composed of a chassis 1 and a sugarcane collection box body 2. On the top surface of the chassis 1, there are fixed two or more guide rails 3 extending horizontally in the left-right direction. At the left and right ends of each guide rail 3, there is a U-shaped groove 3.1 with an upward opening. The sugarcane collection box body 2 is a U-shaped cargo box surrounded by a bottom plate 4 and two openable side doors 5 on the left and right. The two side doors 5 are hinged to the left and right sides of the bottom plate 4 through hinge hinges 6, and are respectively provided with corresponding side door oil cylinders 7 to control the opening and closing of the two side doors 5. On the bottom surface of the bottom plate 4, there is a guide groove 8 extending horizontally in the left-right direction and with a downward opening. The number and position of the guide grooves 8 respectively correspond to the number and position of the guide rails 3 on the top surface of the chassis 1. At the left and right ends of each guide groove 8, there is respectively fixed a locking shaft 8.1. The sugarcane collection box body 2 is buckled and installed on the guide rails 3 on the top surface of the chassis 1 through the guide grooves 8 on the bottom surface of the bottom plate 4. At the same time, the locking shafts 8.1 at the left and right ends of the guide groove 8 are respectively placed at the bottom of the U-shaped grooves 3.1 at the left and right ends of the guide rail 3. On the side of the U-shaped groove 3.1 at the left and right ends of the guide rail 8, there is also installed a locking mechanism 9. The locking mechanism 9 rotatably clamps the locking shaft 8.1 of the guide groove 8 in the U-shaped groove 3.1 of the guide rail 3. Inside the chassis 1, there are also two unlocking driving devices 10, and the two unlocking driving devices 10 respectively control the left and right locking mechanisms 9 to release the clamping of the locking shaft 8.1. Inside the chassis 1, at the horizontally centered position, there is a lifting oil cylinder 11. The cylinder body of the lifting oil cylinder 11 is hinged to the corresponding hinge seat on the chassis 1, and the piston head of the lifting oil cylinder 11 is hinged to the hinge ear at the horizontally centered position on the bottom surface of the bottom plate 4 of the sugarcane collection box body 2. This sugarcane collection box is also equipped with a control system that can control the actions of the side door oil cylinders 7, the unlocking driving devices 10, and the lifting oil cylinder 11.

[0017] Furthermore, the locking mechanism 9 is provided with an F-shaped lock 9.1. The middle crossbar of the F-shaped lock 9.1 is hinged to the guide rail 3 through a lock hinge shaft 9.2. The upper crossbar of the F-shaped lock 9.1 is used as a buckle to be clamped above the locking shaft 8.1. Outside the lock hinge shaft 8.2, there is a torsion spring 9.3 sleeved to keep the buckle of the F-shaped lock 9.1 twisted towards the locking shaft 8.1. At the lower end of the vertical rod of the F-shaped lock 9.1, there is a connecting rod 9.4 to connect all the F-shaped locks 9.1 on the same side into a synchronously linked whole. The unlocking driving device 10 corresponding to the locking mechanism 9 is arranged on the opposite side of the locking mechanism 9. The unlocking driving device 10 is provided with an electric push-pull rod 10.1 and a wire 10.2. The seat body of the electric push-pull rod 10.1 is horizontally installed on the chassis 1 on the opposite side of the locking mechanism 9. The telescopic rod head of the electric push-pull rod 10.1 is connected to one end of the wire 10.2, and the other end of the wire 10.2 is connected to the connecting rod 9.4 of the locking mechanism 9 on the opposite side. The electric push-pull rod 10.1 pulls the connecting rod 9.4 through the wire 10.2 to make the buckles of the F-shaped locks 9.1 of the locking mechanism 9 on this side swing out synchronously to unlock the locking shaft 8.1.

[0018] Furthermore, the two side doors 5 of the sugarcane collecting box 2 are respectively provided with two side door cylinders 7 to control their opening and closing, and the outer side of the side door 5 is provided with a control handle 5.1 that extends outward, the cylinder body of the side door cylinder 7 is hinged on the bottom surface of the bottom plate 4, and the piston head of the side door cylinder 7 is hinged on the control handle 5.1 on the outer side of the side door 5; when the side door cylinder 7 operates the side door 5 to be fully opened, the side door 5 and the bottom plate 4 are in the same plane to form an extension of the bottom plate 4, so that the unloaded sugarcane can reach the side farther away from the sugarcane harvesting row.

[0019] Furthermore, the left-right width of the sugarcane collecting box 2 is greater than the left-right width of the base frame 1 .

[0020] Furthermore, the lifting cylinder 11 adopts a two-stage cylinder to achieve a larger lifting stroke, thereby obtaining a larger unloading inclination angle.

[0021] The sugarcane collecting box is installed at the rear end of the sugarcane combine harvester when in use. Under normal loading conditions, the two side doors 5 of the sugarcane collecting box 2 are closed, the lifting cylinder 11 is retracted, the guide groove 8 of the sugarcane collecting box 2 is horizontally buckled on the guide rail 3 of the chassis 1, and the F-shaped locks 9.1 of the lock mechanisms 9 on the left and right sides are locked to the lock shafts 8.1 on the left and right sides under the action of the torsion springs 9.3. When the sugarcane collecting box 2 is full, it can be turned left or right to unload as needed. When unloading to the left, the side door 5 on the left is opened by the side door cylinder 7. At the same time, the electric push-pull rod 10.1 of the left unlocking drive device 10 pulls the pull wire 10.2 to pull the connecting rod 9.4 of the right locking mechanism 9, so that the F-shaped lock 9.1 of the right locking mechanism 9 releases the locking of the right locking shaft 8.1, and the F-shaped lock 9.1 of the left locking mechanism 9 is kept locked on the left locking shaft 8.1. The lifting cylinder 11 is lifted upward, and the sugarcane collecting box 2 can be turned over by the left locking shaft 8.1. The hinged shaft flips to the left for unloading. After unloading the sugarcane, the lifting cylinder 11 shrinks, and the sugarcane collecting box 2 rotates rightward around the left locking shaft 8.1. When the right locking shaft 8.1 returns, the electric push-pull rod 10.1 of the left unlocking drive device 10 relaxes the pull wire 10.2, so that the F-shaped lock 9.1 of the right locking mechanism 9 resumes the locking of the right locking shaft 8.1 under the action of the torsion spring 9.3. At the same time, the side door cylinder 7 controls the left side door 5 to close, and the whole unloading and reset process is completed. When it is necessary to flip to the right for unloading, the reverse operation can be performed in the same way.
