Description

Technical Field

[0001] This invention relates to the field of bale processing technology, and in particular to a bale picking and unloading transport device with a quick-connect function for tractor units. Background Technology

[0002] After crops are harvested, the straw left in the fields is often collected and processed into livestock feed. Efficient straw recycling and disposal serves two main purposes: firstly, it promptly clears the fields, eliminates the risk of straw burning, and ensures timely plowing and land preparation, providing favorable field conditions for the next season's crops; secondly, baled straw can be supplied as high-quality feed to the livestock industry, alleviating seasonal forage shortages and reducing raw material costs. Therefore, effective straw recycling and processing is of great significance.

[0003] Straw recycling operations generally employ a mechanical baling and transportation model. Under current conditions, if ordinary transport vehicles are used to transport formed bales, loading and unloading require manual labor, resulting in high manpower consumption and low efficiency. Existing dedicated bale processing equipment is mostly single-function, and the adjustment of bale positions after loading relies on manual labor, wasting manpower. Furthermore, the overall cost of the machine is high, and the subsequent maintenance costs are also high. Currently, there is a lack of integrated dedicated transport equipment that integrates bale picking and loading, self-unloading, and bale placement functions, while also enabling rapid docking with tractor units and having lower manufacturing and maintenance costs. In view of this, this solution is proposed after in-depth research into the aforementioned existing technical deficiencies. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a bale picking and unloading transport device with a quick connection function to a tractor unit. This solves the problems of existing bale handling equipment that uses ordinary transport vehicles to transfer formed bales, where loading and unloading work requires manual labor, resulting in high labor costs and low efficiency. Furthermore, existing dedicated bale handling equipment is mostly single-function, and the adjustment of bale positions after loading depends on manual labor, which wastes manpower.

[0029] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0030] Example:

[0031] Please refer to the instruction manual appendix. Figure 1-9 This case relates to a hay bale picking and unloading transport device with a quick connection function for a tractor unit, comprising a pair of identical load-bearing beams 1 and a wheel assembly 2. The wheel assembly 2 is mounted on the pair of load-bearing beams 1. A pair of identical longitudinal beams 3 are mounted on the load-bearing beams 1. Several identical transverse beams 4 are mounted on opposite sides of the pair of longitudinal beams 3. A frame structure is movably mounted on the longitudinal beams 3. A hay bale auxiliary placement structure is mounted on the frame structure. A hay bale picking structure is mounted on the frame structure and located on one side of the frame structure. A quick connection structure is mounted on the pair of load-bearing beams 1.

[0032] In the specific implementation process, it is worth noting that the frame structure in this case includes a pair of identical first longitudinal columns 5, which are movably mounted on a pair of longitudinal beams 3. Several identical first transverse columns 6 are mounted on opposite sides of the pair of first longitudinal columns 5. Several identical second transverse columns 7 are mounted on the opposite sides of the pair of first longitudinal columns 5. The second transverse columns 7 are divided into two groups, with one end of each group mounted on the opposite side of the pair of first longitudinal columns 5. A second longitudinal column 8 is mounted on the other end of each group of second transverse columns 7. Several identical support columns 9 are mounted on the outer sides of the two groups of second transverse columns 7. A pair of identical railings 10 are mounted on the upper ends of the support columns 9. Several identical first support plates 11 are mounted on the first transverse columns 6. The support plate 11 is divided into two groups. The two groups of first support plates 11 are parallel to each other and equidistant. A first support rod 12 is installed on each of the two groups of first support plates 11. Several second support plates 13 with the same structure are installed on each of the two groups of second crossbars 7. The height of the several second support plates 13 is lower than that of the two groups of first support plates 11. The several second support plates 13 are divided into two groups. The two groups of second support plates 13 are parallel to each other and equidistant. A second support rod 14 is installed on each of the two groups of second support plates 13. This arrangement can fully meet the stability requirements, prevent the bales from slipping or tipping over during transportation, and improve the stability of transshipment. At the same time, sufficient gaps are left so that soil clods and soil particles stuck to the bales fall into the field during operation and shaking, without the need for additional cleaning.

[0033] The hay bale placement aid structure in this case includes a pair of identical electric slide rails 15. Both electric slide rails 15 are installed on the first horizontal column 6 and located on both sides of the first support rod 12. Each pair of electric slide rails 15 has a connector 16 installed on its sliding end. The connector 16 is fixed to the sliding end of the pair of electric slide rails 15 by screws 17. A lever 19 is movably installed on the connector 16 through a pivot 18. Each connector 16 has a pair of identical springs 20 installed on it. One end of each spring 20 is installed on the connector 16, and the other end is installed on the lever 19.

[0034] It is worth noting that the bale picking structure in this case includes a pair of identical first connecting seats 21, both of which are installed on the longitudinal beam 3. A swing arm 22 is movably installed on the pair of first connecting seats 21. A first hydraulic cylinder 23 is movably connected to the swing arm 22. The telescopic end of the first hydraulic cylinder 23 is movably connected to the swing arm 22. A second connecting seat 24 is movably installed at the bottom of the first hydraulic cylinder 23. The second connecting seat 24 is installed on the load-bearing beam 1. A first supporting net 25 is installed on the swing arm 22. A second supporting net 26 is installed on the swing arm 22. The second supporting net 26, the first supporting net 25, and the swing arm 22 are on the same plane. A bale-pulling barrier net 27 is installed on the first supporting net 25. One side of the bale-pulling barrier net 27 is a horizontal structure, and the other side is a structure that gradually slopes outward. A flat barrier net 28 is installed on the second supporting net 26.

[0035] In this case, a pair of load-bearing beams 1 extend to opposite sides until they fit together. The quick connection structure includes a locking box 29, which is fitted onto a pair of load-bearing beams 1 with the same structure. A connecting box 30 is installed on the locking box 29. A protrusion 31 is embedded in the connecting box 30. A through hole 32 is opened on the protrusion 31. An electric locking component is embedded on the protrusion 31.

[0036] The electronically controlled locking assembly in this case includes a mounting shell 33, which is mounted on a protrusion 31. A pair of identical sliding grooves 34 are formed on opposite inner walls of the mounting shell 33. A micro motor 35 is mounted at the bottom of the mounting shell 33. A threaded rod 36 is mounted on the drive end of the micro motor 35. A locking tooth 37 is spirally connected to the threaded rod 36. The locking tooth 37 is a cylinder with a hollow threaded groove. The locking tooth 37 is spirally connected to the threaded rod 36 and extends to the inner side of the mounting shell 33. A pair of identical limiting blocks 38 are provided on the locking tooth 37. The pair of limiting blocks 38 are mounted on the locking tooth 37 and located in a pair of sliding grooves 34 on the mounting shell 33.

[0037] Among them, a pair of identical second hydraulic cylinders 39 are installed on the longitudinal beam 3. One end of the pair of second hydraulic cylinders 39 is installed on the longitudinal beam 3, and the other end is movably installed on the lower wall of the first transverse column 6.

[0038] In this case, the paddle 19 is equipped with several identical sharp teeth 40, which are horizontally mounted on the paddle 19.

[0039] Among them, the locking box 29 is equipped with two pairs of pins 41 with the same structure, and the positions of the two pairs of pins 41 correspond to each other;

[0040] A pair of identical protruding columns 42 are installed on the opposite side of a pair of longitudinal beams 3. The pair of protruding columns 42 are horizontally installed on the opposite side of a pair of longitudinal beams 3 and are positioned correspondingly. A pair of identical perforated plates 43 are installed on the opposite side of a pair of first longitudinal columns 5. The pair of perforated plates 43 are vertically installed on the opposite side of a pair of first longitudinal columns 5. The pair of protruding columns 42 are inserted into the pair of perforated plates 43.

[0041] A pad 44 is installed on a pair of load-bearing beams 1. In the specific implementation process, non-rigid materials such as rubber or plastic can be used. The pad 44 forms a relatively flexible support between the load-bearing beam 1 and the first longitudinal column 5, which prevents the first longitudinal column 5 from being twisted by force and promotes structural stability.

[0042] In summary, when using this equipment for hay bale transportation, it needs to be connected to the tractor unit. The operator needs to install the same quick-connect structure as this device on the tractor end. During connection, adjust the tractor unit's position, insert the two protrusions 31 into the connecting box 30 for initial positioning, and then manually press the locking switch. At this time, the micro motor 35 drives the threaded rod 36 to rotate forward, and the locking teeth 37 on the threaded rod 36 extend outward. The locking teeth 37 on the two protrusions 31 insert into their respective through holes 32. The quick-connect connection is now complete, and the tractor unit can move the equipment forward to pick up hay bales. The operator drives the tractor unit so that the tilted end of the bale-removing net 27 is close to the outer edge of the front hay bale. In actual operation, even if not perfectly aligned... It can also be picked up normally because one side of the bale-pulling net 27 is a horizontal structure, and the other side is a structure that gradually slopes outwards. When the end of the bale-pulling net 27 contacts the bale, the end will push the bale. As the bale-pulling net 27 gets closer to the bale, it will slide along the inclined wall of the bale-pulling net 27. In this process, it will gradually straighten. Finally, the bale will be restricted on both sides between the bale-pulling net 27 and the flat net 28, and the lower side will be supported by the first support net 25 and the second support net 26. At this time, the worker presses the button to load the truck. At this time, the first hydraulic cylinder 23 extends, and the swing arm 22 rotates upward along the first connecting seat 21. Through the lever principle, it drives the bale to move. When the swing arm 22 moves to the vertical position, the bale will roll along the flat net 28 under the action of inertia and then fall to the first support rod 12. Because the first support rod 12 is higher than the second support rod 14, under the influence of gravity and inertia, the bale will tilt and roll away from the swing arm 22 until it lands on the second support rod 14 away from the swing arm 22 and close to the railing 10. At this point, the first bale is loaded. The second bale is picked up under the same principle and rolls down along the flat barrier 28. Since the first bale is already on the side away from the swing arm 22, and its position is higher than the pair of first support rods 12, the second bale will be squeezed by the first bale under the influence of gravity and roll towards the side closer to the swing arm 22 via the first support rod 12 until it lands on the second support rod 14 and the railing 10 on the side closer to the swing arm 22. In this case, the third bale is picked up in the same way. Three bales of hay roll down the flat baffle 28. At this point, bales are already on both sides. The third bale will fall between the first two and adhere to the second support rod 14. Simultaneously, the sliding ends of a pair of electric slide rails 15 operate, driving the lever 19 to move the bales. Teeth 40 tighten the bales to prevent loosening. While moving the bales, the lever 19 experiences a counterforce, maintaining a vertical position due to leverage. The bales on the cart are moved to the rear, and then the pair of electric slide rails 15 reset. If a bale obstructs the reset process, the lever 19 will shift to a horizontal position, causing the spring 20 to extend. After passing the obstruction, the spring 20 returns to its original shape, pulling the lever 19 back to its vertical position. The next set of bales can then be picked up and placed until the cart is full.During unloading, the second hydraulic cylinder 39 extends under the control of the operator. At this time, a pair of perforated plates 43 rotate around a pair of protruding pillars 42, pushing the frame structure upwards and tilting. Under gravity, the bales on the vehicle slide down and fall, thus completing the unloading process. After the work is finished, the operator resets the equipment. This equipment features quick connection to a tractor, bale picking, assisted placement, and self-unloading functions, greatly improving work efficiency, reducing labor costs, and has low manufacturing and maintenance costs. It can promote better bale recycling and indirectly contribute to the better development of the livestock farming industry.
