Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a ton bag loading and unloading device and a harvester. Background Art

[0002] Potatoes have shallow roots, so ridge planting can increase soil depth to a certain extent. At the same time, ridge planting can mix organic fertilizers and cover soil together, which can increase soil fertility to a certain extent and improve potato quality and yield.

[0003] Existing potato harvesters are generally designed with only one receiving station. By installing a ton bag in the receiving station, the separated potatoes can be collected in batches. When the ton bag is full, the harvester will unload the ton bag onto the land. Since the ridge spacing of the potato planting field is generally small, the ton bag may block the movement path of the harvester after it falls to the ground, thereby interfering with the harvesting operation of the harvester on the adjacent ridges.

[0004] Therefore, a ton bag loading and unloading device and a harvester are proposed. By reasonably arranging the installation position of the ton bag belt, the ton bag filled with potatoes will not interfere with the subsequent moving path of the harvester after it falls to the ground, thereby not affecting the harvesting operation on adjacent ridges and improving the harvesting efficiency.

[0042] Embodiment 1

[0043] like Figure 1-11 As shown, in one embodiment of the utility model, a ton bag loading and unloading device is provided, comprising a frame 10, a support frame 20, a flip structure 30, three bag hanging mechanisms 40, a first sliding mechanism 50 and two second sliding mechanisms 60. The frame 10 is provided with two hoppers 11 arranged side by side along the width direction of the frame 10, and a discharge port is provided at the bottom of the hopper 11. The support frame 20 is rotatably arranged on the frame 10 and is located below the two hoppers 11. The support frame 20 is used to support the ton bag, and the flip structure 30 is used to drive the support frame 20 to flip.

[0044] The three bag hanging mechanisms 40 are arranged at intervals along the width direction of the frame 10. The bag hanging mechanisms 40 are used to hook the hanging ears of the ton bag, or release the hooking state of the hanging ears of the ton bag. The middle bag hanging mechanism 40 is located between the two discharge ports, and the two adjacent bag hanging mechanisms 40 are arranged on both sides of the discharge port. The first sliding mechanism 50 can drive the middle bag hanging mechanism 40 to move, and the two second sliding mechanisms 60 correspond to the two outer bag hanging mechanisms 40 respectively. The second sliding mechanism 60 can drive the outer bag hanging mechanism 40 to move, and the sliding direction of the second sliding mechanism 60 is parallel to the sliding direction of the first sliding mechanism 50.

[0045] For the convenience of description, the bag hanging mechanism 40 located in the middle is recorded as bag hanging mechanism 40a, the two outer bag hanging mechanisms 40 are recorded as bag hanging mechanism 40b and bag hanging mechanism 40c respectively, the hopper 11 between the bag hanging mechanism 40a and the bag hanging mechanism 40b is recorded as hopper 11a, and the hopper 11 between the bag hanging mechanism 40a and the bag hanging mechanism 40c is recorded as hopper 11b.

[0046] When the bag hanging mechanism 40a cooperates with the bag hanging mechanism 40b to hook the hanging ears of the ton bag, the bag hanging mechanism 40c and the hopper 11b will be in an idle state. After the conveying mechanism conveys the separated potatoes to the hopper 11a, the potatoes will be introduced into the ton bag. When the ton bag is full, the operator operates the bag hanging mechanism 40a and the bag hanging mechanism 40b to release the hook state of the hanging ears. Then, the flip structure is started to drive the support frame 20 to flip, and the ton bag can be unloaded onto the land.

[0047] Then, the operator hangs a new ton bag on the bag hanging mechanism 40a and the bag hanging mechanism 40c. When the ton bag is full, the operator operates the bag hanging mechanism 40a and the bag hanging mechanism 40c to release the hook state of the hanging ears. Then, the flipping structure is started to drive the support frame 20 to flip, and the ton bag can be unloaded onto the land.

[0048] The present embodiment discloses a ton bag loading and unloading device, which reasonably arranges the positions of three bag hanging mechanisms 40, so that the middle bag hanging mechanism 40 can cooperate with one of the outer bag hanging mechanisms 40 to hook the hanging ears of the ton bag, and the other bag hanging mechanism 40 and the hopper 11 will be in an idle state. After the ton bag is full, the operator operates the above two bag hanging mechanisms 40 to release the hooking state of the hanging ears, and the flip structure 30 cooperates with the support frame 20 to unload the ton bag onto the land. At the same time, with the cooperation of the first sliding mechanism 50 and the second sliding mechanism 60, it is convenient for the operator to pull the bag hanging mechanism 40 to operate. The ton bag loading and unloading can reasonably arrange the position of the ton bag, so that when the harvester harvests each ridge in turn, the ton bag can be unloaded onto the harvested ridge. In this way, the ton bag on the land is prevented from interfering with the moving path of the harvester, thereby improving the harvesting efficiency.

[0049] In one embodiment, the bag hanging mechanism 40 includes a base 41, two hooks 42, a linkage assembly 43 and a locking assembly 44. The base 41 is slidably matched on the first sliding mechanism 50 or the second sliding mechanism 60, and the two hooks 42 are both rotatably arranged on the base 41. The linkage assembly 43 is respectively connected to the two hooks 42 so that the two hooks 42 can rotate synchronously. The locking assembly 44 is used to lock one of the hooks 42 on the base 41 so that the two hooks 42 remain in a hooked state.

[0050] Specifically, the locking assembly 44 includes a limit block 441, an extension arm 442, a first tube 443, a limit pin 444, a second tube 445 and an elastic member 446. The limit block 441 is fixed on the base 41, and a limit hole is provided on the limit block 441. The extension arm 442 is fixed on the hook 42, and the first tube 443 is fixed on the side of the extension arm 442 away from the limit block 441. The limit pin 444 is movably arranged in the first tube 443, one end of the limit pin 444 extends out of the extension arm 442 and can be plugged into the limit hole, and the other end of the limit pin 444 extends out of the first tube 443. The second tube 445 is movably sleeved outside the first tube 443, and the second tube 445 is connected to the limit pin 444. The elastic member 446 is disposed in the first tube body 443 , and is used to apply elastic force to the limiting pin 444 to prevent the limiting pin 444 from retreating into the first tube body 443 .

[0051] When the hook 42 needs to be locked in the hooking state, the operator only needs to hold the second tube 445 to drive the extension arm 442 and the hook 42 to rotate, and the other hook 42 will also rotate synchronously driven by the linkage assembly 43. Then, the operator pulls out the second tube 445, and the second tube 445 will drive the limit pin 444 to return to the first tube 443. When the limit pin 444 is aligned with the limit hole on the limit block 441, the second tube 445 is released, and the limit pin 444 is inserted into the limit hole driven by the elastic member 446. In this way, the extension arm 442 and the two hooks 42 cannot rotate, so that the two hooks 42 remain in the hooking state, avoiding the falling off of the ear of the ton bag, and ensuring the collection effect of the ton bag on potatoes.

[0052] Furthermore, the limiting pin 444 includes a first cylinder, a second cylinder and a third cylinder which are coaxial and connected in sequence, the outer diameter of the first cylinder is larger than the outer diameter of the second cylinder, and the outer diameter of the second cylinder is larger than the outer diameter of the third cylinder. The first cylinder is plugged into the limiting hole, the second cylinder is located in the first tube 443, the elastic member 446 is a spring, the elastic member 446 is sleeved outside the second cylinder, and the two ends of the elastic member 446 respectively abut against the end wall of the first tube 443 and the end wall of the first cylinder; the third cylinder extends out of the first tube 443 and the second tube 445, and the third cylinder is provided with a retaining spring 447 for limiting the second tube 445 from falling off. When the second tube 445 is pulled outward, the second tube 445 will push the retaining spring 447, thereby driving the limiting pin 444 to retreat into the first tube 443. When the second tube 445 is released, the elastic force of the elastic member 446 will quickly push the limiting pin 444 out of the first tube 443 again.

[0053] Furthermore, the linkage assembly 43 includes a connecting rod 431 and two rocker arms 432. The two rocker arms 432 are rotatably disposed on the base 41, and the connecting rod 431 is respectively connected to the two rocker arms 432. Each rocker arm 432 corresponds to a hook 42. The rotation axis 36 of the rocker arm 432 is colinear with the rotation axis 36 of the hook 42, and the rocker arm 432 and the corresponding hook 42 do not rotate relative to each other. The connecting rod 431, the two rocker arms 432 and the base 41 constitute a parallelogram connecting rod 431 structure. When the operator rotates the extension arm 442, not only the hook 42 connected to the extension arm 442 is driven to rotate, but also the other hook 42 is driven to rotate. The structural design is ingenious and convenient for operating the hook 42.

[0054] In one embodiment, the first sliding mechanism 50 includes a first support arm 51, a first guide rail 52 and a first sliding member 53. The first support arm 51 is provided on the frame 10, the first guide rail 52 is provided on the first support arm 51, and the first sliding member 53 is slidably fitted on the first guide rail 52 and connected to the base 41. Limited by the overall structural layout, only one first sliding member 53 is designed, so in order to prevent the base 41 from being unstable, the base 41 rests on the support of the first guide rail 52.

[0055] The second sliding mechanism 60 includes a second support arm 61, a second guide rail 62 and at least two second sliding members 63. The second support arm 61 is provided on the frame 10, the second guide rail 62 is provided on the second support arm 61, and the second sliding member 63 is slidably fitted on the second guide rail 62 and connected to the base 41. By designing the first sliding mechanism 50 and the second sliding mechanism 60, the operator can pull the base 41, thereby facilitating the bag hanging operation on the ton bag.

[0056] In one embodiment, the flip structure includes a lifting assembly and two guide assemblies, and the lifting assembly is used to drive the support frame 20 to lift. The two guide assemblies are arranged on both sides of the support frame 20, and the guide assemblies include a first slide 31, a second slide 32, a third slide 33, a first pulley 34 and a second pulley 35. The first slide 31 and the second slide 32 both extend vertically and are respectively arranged on the frame 10. The third slide 33 is close to the bottom of the frame 10, the third slide 33 is connected with the first slide 31, and is located on the side of the first slide 31 away from the second slide 32. The end of the third slide 33 away from the first slide 31 is inclined downward. The first pulley 34 is slidably fitted in the first slide 31, and the second pulley 35 is slidably fitted in the second slide 32. The first pulley 34 and the second pulley 35 are both connected to the support frame 20. Two loading positions are provided on the support frame 20, and each loading position is provided with a discharge port 21.

[0057] After the operator operates the hook 42 mechanism to release the hook state of the hanging ear, the lifting assembly drives the support frame 20 to descend. When the second pulley 35 descends to the bottom of the second slide groove 32, the support frame 20 can no longer continue to descend, and the first pulley 34 will be at the connection between the third slide groove 33 and the first slide groove 31. If the lifting assembly continues to drive the support frame 20 to descend at this time, the ton bag will press down the support frame 20 under the action of gravity, so that the first pulley 34 slides into the third slide groove 33, so that the end of the support frame 20 close to the discharge port 21 will tilt downward, so that the ton bag will slide on the support frame 20 and slide out of the discharge port 21 and fall to the ground, so that the unloading operation of the ton bag is realized.

[0058] In one embodiment, the lifting assembly includes a shaft 36, a motor and two pull ropes 37. The shaft 36 is rotatably arranged on the frame 10, the shaft 36 is located below the collecting pocket, and the motor (not shown in the drawings) is arranged on the frame 10 and is used to drive the shaft 36 to rotate. The two pull ropes 37 are respectively close to both sides of the frame 10, one end of the pull rope 37 is connected to the support frame 20, and the other end of the pull rope 37 is wound around and fixed on the shaft 36.

[0059] Two fixed pulleys are provided on the frame 10, and the pull rope 37 passes through the fixed pulleys and is connected to the support frame 20. When the motor drives the rotating shaft 36 to rotate so as to drive the two pull ropes 37 to reel in or unreel, the lifting operation of the support frame 20 is realized, and the flipping operation of the support frame 20 can be realized with the cooperation of the two guide components.
