[0040] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0041] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] As described in the background technology, the traction baler of the related technology includes a baling chamber, which can compress and bundle bales of grass. A bale pushing device is arranged in the baling chamber, and the bale pushing device includes a push plate and a driving member. The push plate is slidably arranged in the baling chamber, and the driving member is usually arranged as a hydraulic cylinder. When multiple compressed bales are bundled in the baling chamber, the hydraulic cylinder drives the push plate to move, so that the push plate can push out all the multiple bales of grass at one time, so that the multiple bales of grass fall into the grassland.

[0043] However, the area of ​​the grassland is large, and the large grassland is divided into multiple areas. The grass in the same area is harvested and baled and then piled at the same location. A large number of bales are piled in each area, and the transportation equipment for transporting bales is limited in the number of bales that can be transported at one time. When the number of bales stacked at the same location by the bale pushing device is greater than the number of bales that can be transported at one time by the transportation equipment, for example, there are 15 bales piled at the same location, but the transportation equipment can only transport 10 bales at a time, it will cause the transportation equipment to be underloaded during the next transportation, or the transportation equipment needs to be moved to the next bale stacking point for loading when it is not full. When the transportation equipment is not full for multiple times, the number of transportation times of the transportation equipment is increased. When the transportation equipment is moved for multiple times for loading, the transportation distance of the transportation equipment is increased, thereby reducing the transportation efficiency of the transportation equipment.

[0044] In view of the above technical problems, an embodiment of the present application provides a bale pushing device, when the driving block is opposite to the groove with the largest depth and the grass pusher is reset, the driving block can abut against the bottom wall of the groove with the largest depth, so that the sliding selector moves relative to the grass pusher, and at this time, the edge of the first second opening in the propulsion direction of the grass pusher can abut against the grass pushing tooth, so that the second opening squeezes the grass pushing tooth to rotate, thereby causing the first grass pushing tooth in the propulsion direction of the grass pusher to rotate into the groove body, while the second second opening and the third second opening in the propulsion direction of the grass pusher are not abutted against the grass pushing tooth; When the driving block is opposite to the groove with the second largest depth and the grass pusher is reset, the driving block can abut against the bottom wall of the groove with the second largest depth, so that the sliding selector moves relative to the grass pusher. At this time, the edge of the first second opening in the propulsion direction of the grass pusher can first abut against the grass pushing tooth, and the sliding selector continues to move, so that the edge of the second second opening in the propulsion direction of the grass pusher abuts against the grass pushing tooth, so that the second opening squeezes the grass pushing tooth to rotate, so that the first grass pushing tooth and the second grass pushing tooth in the propulsion direction of the grass pusher rotate into the groove body, and the third second opening in the propulsion direction of the grass pusher The opening of the grass pusher is not in contact with the grass pushing teeth; when the driving block is opposite to the groove with the smallest depth and the grass pusher is reset, the driving block can abut on the bottom wall of the groove with the smallest depth, so that the sliding selector moves relative to the grass pusher. At this time, the edge of the first second opening in the propulsion direction of the grass pusher can first abut against the grass pushing teeth, and the sliding selector continues to move, so that the edge of the second second opening in the propulsion direction of the grass pusher abuts against the grass pushing teeth, and the sliding selector moves further, so that the edge of the third second opening in the propulsion direction of the grass pusher abuts against the grass pushing teeth, so that the three second openings are squeezed in sequence. The three grass pushing teeth rotate, so that the first grass pushing tooth, the second grass pushing tooth and the third grass pushing tooth in the propulsion direction of the grass pusher rotate into the slot body, so that the first three grass pushing teeth of the five grass pushing teeth are all rotated into the slot body, and a specified number of grass pushing teeth are driven by the grass pushing tooth selection device to rotate into the slot body, so that a specified number of grass bales can be pushed down at one time, and the number of grass bales at the same position on the grassland can be adjusted, so that the transportation equipment can reach a full state when transporting multiple grass bales at the same position for multiple times, thereby improving the transportation efficiency when transporting multiple grass bales at different positions on the grassland.

The five grass-pushing teeth 300 are evenly and spacedly distributed on the grass-pushing device 100, and the five grass-pushing teeth 300 correspond to the five first openings 120 one by one. The two sides of the grass-pushing teeth 300 are fixedly provided with connecting shafts 140 that penetrate and are rotatably connected to the opposite surface of the groove body 110. The elastic member 310 includes a torsion spring, which is sleeved on the connecting shaft 140, and one end of the torsion spring is fixedly connected to the groove body 110. 0, and the other end is fixedly connected to the grass pushing tooth 300; the grass pushing tooth selection device 400 is configured to, when the grass pusher 100 is reset, drive the first three grass pushing teeth 300 of the five grass pushing teeth 300 to rotate in sequence along the propulsion direction of the grass pusher 100, so that the three grass pushing teeth 300 rotate along the first opening 120 into the groove body 110; a bearing 150 is provided on the outer wall of the grass pusher 100, and the bearing 150 is used to be slidably connected in the fixing rod 510.

[0052] By adopting the above technical solution, the grass bale after compression and bundling in the baling chamber is located in the baling chamber, and multiple grass bales are located in multiple accommodating spaces 320. The grass pushing tooth selection device 400 can be set to drive three grass pushing teeth 300 to rotate in sequence along the propulsion direction of the grass pushing device 100 when the grass pusher 100 is reset, so that the grass pushing teeth 300 are rotated into the groove body 110. When the driving member 200 drives the grass pusher 100 to advance in the guide groove, the grass pushing teeth 300 extending out of the grass pusher 100 can drive the grass bale out, while the remaining grass pushing teeth 300 rotated into the groove body 110 cannot push the grass bale out. The grass pushing tooth selection device 400 drives the specified number of grass pushing teeth 300 to rotate to The trough 110 is provided with a plurality of grass bales, which can be easily pushed down in one time, and the number of grass bales at the same position on the grassland can be easily adjusted, so that the transport equipment can be fully loaded when transporting multiple grass bales at the same position for multiple times, thereby improving the transport efficiency when transporting multiple grass bales at different positions on the grassland; and after the specified number of grass pushing teeth 300 are lowered, it is convenient to push out the grass bales at the specified position, so that the user does not need to push out all the grass bales and then select the grass bales to be used, which further improves the grass bale pushing effect; the elastic member 310 can be used to reset the grass pushing teeth 300 rotated into the trough 110, so that the grass pushing teeth 300 are in a state of partially extending out of the grass pusher 100.

[0053] Combination Figures 2 to 5 The grass pushing tooth selection device 400 includes a sliding selector 410 and a driving mechanism 420. The sliding selector 410 is arranged in the slot body 110. The sliding selector 410 is provided with at least one second opening 411. The second opening 411 is used for the grass pushing tooth 300 to pass through. The driving mechanism 420 is configured to drive the sliding selector 410 to move relative to the grass pushing device 100 when the grass pushing device 100 is reset, so that the sliding selector 410 drives at least one grass pushing tooth 300 to rotate to the slot body 110 in sequence along the propulsion direction of the grass pushing device 100.

[0054] In this embodiment, two sliding selectors 410 are provided, and the two sliding selectors 410 are respectively arranged in two grass pushers 100, and the sliding selectors 410 are located between the bottom wall of the groove body 110 and the connecting shaft 140; each sliding selector 410 has three second openings 411, and the three second openings 411 correspond one by one to the first three grass pushing teeth 300 in the propulsion direction of the grass pusher 100; the driving mechanism 420 is configured to drive the sliding selector 410 to move relative to the grass pusher 100 when the grass pusher 100 is reset, so that the sliding selector 410 drives the first three grass pushing teeth 300 in the propulsion direction of the grass pusher 100 to rotate into the groove body 110.

[0055] By adopting the above technical solution, when the grass pusher 100 is reset, the driving mechanism 420 can drive the sliding selector 410 to move relative to the grass pusher 100, so that the grass pusher 100 moves along the propulsion direction of the grass pusher 100, so that the second opening 411 on the sliding selector 410 and the first opening 120 on the grass pusher 100 are staggered with each other. At this time, the sliding selector 410 can abut against the grass pushing teeth 300, so that the sliding selector 410 drives the grass pushing teeth 300 to rotate into the groove body 110. The number of the second openings 411 determines the number of grass pushing teeth 300 that the sliding selector 410 can drive. The setting of the sliding selector 410 and the second opening 411 can drive multiple grass pushing teeth 300 to rotate while moving, thereby improving the driving effect of multiple grass pushing teeth 300.

[0056] Combination Figures 2 to 6 The driving mechanism 420 includes a driving block 421 and a bottom plate 422. The driving block 421 is fixedly disposed on the sliding selector 410, and the bottom plate 422 is used to be fixedly disposed on the baling chamber. The driving block 421 is configured to abut against the bottom plate 422 when the grass pusher 100 is reset, thereby driving the sliding selector 410 to move relative to the grass pusher 100.

[0057] In this embodiment, two driving blocks 421 are provided, and the two driving blocks 421 are respectively arranged on two sliding selectors 410, and the cross-section of the driving block 421 is arranged in a rectangular shape; one bottom plate 422 is provided, and the bottom plate 422 spans between the two grass pushers 100, and the oil cylinder is fixedly arranged on the surface of the bottom plate 422 facing the frame 500.

[0058] By adopting the above technical solution, when the grass pusher 100 is reset, the grass pusher 100 can drive the sliding selector 410 to move synchronously. When the driving block 421 abuts against the bottom plate 422, the bottom plate 422 prevents the driving block 421 from following the movement of the sliding selector 410, so that the sliding selector 410 stops moving. At this time, the grass pusher 100 continues to reset, and relative movement occurs between the sliding selector 410 and the grass pusher 100, so that the second opening 411 is staggered with the first opening 120, so that the sliding selector 410 drives the grass pushing teeth 300 to rotate. The arrangement of the driving block 421 and the bottom plate 422 has a simple structure, which improves the driving effect of the relative movement between the grass pusher 100 and the sliding selector 410.

[0059] Combination Figures 5 to 8 The driving mechanism 420 also includes a selection plate 423, which is slidably arranged on the bottom plate 422 along a direction perpendicular to the movement direction of the grass pusher 100. A plurality of grooves 424 are provided on the selection plate 423 along the movement direction of the selection plate 423, and the depths of the plurality of grooves 424 increase sequentially.

[0060] In this embodiment, there are three grooves 424, and the three grooves 424 are divided into two groups. The two groups of grooves 424 are respectively opposite to the grass pushers 100 on both sides. The grooves 424 are matched with the rectangular driving block 421. The side of the groove 424 close to the propulsion direction of the grass pusher 100 passes through the selection plate 423, and the side of the groove 424 close to the reset direction of the grass pusher 100 is closed.

[0061] Combination Figures 5 to 8 The driving mechanism 420 also includes a fixing component 430, which is used to fix the selection plate 423 so that the driving block 421 is opposite to one of the multiple grooves 424. When the driving block 421 abuts against the bottom walls of the multiple grooves 424 from the largest depth to the smallest depth in sequence, the driving sliding selector 410 is driven to move step by step, so as to drive the multiple grass pushing teeth 300 in the propulsion direction of the grass pusher 100 to rotate into the groove body 110 in sequence.

[0062] By adopting the above technical solution, the selection plate 423 can be fixed by the fixing component 430, so that the selection plate 423 drives any one of the grooves 424 to be opposite to the driving block 421. When the driving block 421 is opposite to the groove 424 with the largest depth and the grass pusher 100 is reset, the sliding selector 410 can drive the driving block 421 to abut against the bottom wall of the groove 424 with the largest depth. At this time, the sliding selector 410 moves relative to the grass pusher 100, so that the sliding selector 410 drives the first grass pushing tooth 300 to rotate into the groove body 110; when the driving block 421 is opposite to the second groove 424 When the grass pusher 100 is reset, the sliding selector 410 can drive the driving block 421 to abut against the bottom wall of the second groove 424. At this time, the sliding selector 410 moves again relative to the grass pusher 100, so that the sliding selector 410 drives the first and second grass pushing teeth 300 to rotate into the groove body 110; by selecting different grooves 424, the sliding selector 410 can drive different numbers of grass pushing teeth 300 to rotate into the groove body 110. The user can select different grass pushing teeth 300 to rotate into the groove body 110 as needed, thereby further improving the driving effect of the grass pushing teeth 300.
