DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without paying creative labor belong to the scope of the utility model protection.

[0020] Embodiment 1: a bitter bean harvesting device, as Figs. 1-2As shown, including the shell 1, the shell 1 is a hollow box structure, the left end of the shell 1 is fixedly provided with a first shear 2, the shell 1 is slidably provided with a sliding rod 3, the left end of the sliding rod 3 passes out of the shell 1 and is fixedly provided with a forwardly extending knife bar 4, the right end of the knife bar 4 is fixedly provided with a second shear 5, the first shear 2 and the second shear 5 are arranged at intervals left and right, and the cutting edges of the first shear 2 and the second shear 5 are arranged oppositely.

[0021] The shell 1 is provided with a driving mechanism 6, which is used to drive the sliding rod 3 to slide, so as to drive the second shear 5 to move and shear the Sophora Viciiflora Bge branch, so as to realize the purpose of harvesting Sophora Viciiflora Bge, specifically, the driving mechanism 6 includes a first rotating shaft 61 rotatably arranged in the shell 1, a first spur gear 62 fixedly arranged on the first rotating shaft 61, a plurality of tooth grooves 63 fixedly arranged on one side of the sliding rod 3 and spaced apart along the extension direction of the sliding rod 3, the sliding rod 3 is engaged with the first spur gear 62 through the tooth grooves 63, a second rotating shaft 64 rotatably arranged in the shell 1, a second spur gear 65 fixedly arranged on the second rotating shaft 64, the second spur gear 65 engaged with the first spur gear 62, and a handle 66 fixedly arranged on the second spur gear 65; by pulling the handle 66 backward, the sliding rod 3 can be driven to slide rightward through the second spur gear 65 and the first spur gear 62, and in turn the second shear 5 is driven to move rightward to shear the Sophora Viciiflora Bge branch.

[0022] The number of teeth of the second spur gear 65 is greater than that of the first spur gear 62, so that when the second spur gear 65 drives the first spur gear 62 to transmit, the transmission is speed-increasing, so that the handle 66 on the second spur gear 65 only needs to rotate a small angle to drive the first spur gear 62 to rotate one revolution, and in turn the sliding rod 3 and the second shear 5 are driven to slide rightward to shear the Sophora Viciiflora Bge branch, which increases the convenience of operation.

[0023] The right end of the shell 1 is fixedly provided with a handle 7 extending to the right, and the handle 7 and the grip 66 form an acute angle less than 90°; the left end of the handle 7 is provided with a sliding groove in communication with the inside of the shell 1, the right end of the sliding rod 3 is slidingly inserted into the sliding groove, the sliding groove can guide the sliding rod 3 in the left-right direction, a groove 71 is formed in the handle 7 along the extension direction of the handle 7, the left end of the groove 71 is in communication with the sliding groove, and the cross section of the groove 71 is larger than that of the sliding groove, the right end of the sliding rod 3 penetrates into the groove 71 and is fixedly provided with a limiting plate 72, the limiting plate 72 slidingly abuts against the inner wall of the groove 71, the limiting plate 72 can limit the left-right position of the cutter bar 4 and the second pruning shear 5 at the left end of the sliding rod 3, so as to avoid that the distance between the second pruning shear 5 and the first pruning shear 2 is too large to affect the cutting; a first spring 73 is arranged in the groove 71, the two ends of the first spring 73 abut against the right end of the groove 71 and the limiting plate 72 respectively, the first spring 73 is used to release the grip 66 after the handle 7 is gripped to complete the pruning of the bitter bean, the first spring 73 pushes the sliding rod 3 to move left to complete the reset of the sliding rod 3, the cutter bar 4, the second pruning shear 5 and the grip 66, so as to facilitate the next time to grip the grip 66 to harvest the bitter bean.

[0024] A clamping mechanism 8 is arranged on the shell 1, which is used to clamp the bitter bean branches when pruning the bitter bean, so that the harvested bitter bean can be put into the collection container with one hand, without holding the collection container with one hand and using the pruning shear type harvesting tool with the other hand, thereby improving the harvesting efficiency; specifically, the clamping mechanism 8 comprises two left and right spaced apart supports 81, the left support 81 is fixedly arranged on the cutter bar 4, and the right support 81 is fixedly arranged on the shell 1; a push rod 86 sliding left and right is arranged in the support 81, the two push rods are fixedly provided with a clamping plate 82 at the opposite end, the two clamping plates 82 are fixedly provided with rubber pads 83 at the opposite side, the right side of the left rubber pad 83 is located to the right of the second pruning shear 5, and the left side of the right rubber pad 83 is located to the left of the first pruning shear 2, so that the two rubber pads 83 can contact the bitter bean branches first when pruning the bitter bean branches, avoiding that the first pruning shear 2 or the second pruning shear 5 contacts the bitter bean branches first, causing the bitter bean branches to shake and the bitter beans to fall off from the pods.

[0025] The second spring 84 is sleeved on the push rod 86, and the two ends of the second spring 84 abut against the support 81 and the clamping plate 82 respectively. The second spring 84 can exert force on the clamping plate 82 and the rubber pad 83 during the clamping and movement to the two sides of the clamping plate 82 and the rubber pad 83, so as to improve the clamping force and stability of the clamping plate 82 and the rubber pad 83 on the Sophora japonica branch. When the clamping plate 82 and the rubber pad 83 are separated from the Sophora japonica branch, the second spring 84 can drive the clamping plate 82 and the rubber pad 83 to reset. The end of the push rod 86 away from the clamping plate 82 penetrates through the support 81 and is fixedly provided with a limiting block 85, and the limiting block 85 abuts against the support 81, so as to prevent the push rod 86 from being separated from the support 81.

[0026] When the handle 66 is loosened, the first spring 73 drives the sliding rod 3 to move left to reset the sliding rod 3, the cutter rod 4, the second cutting knife 5 and the handle 66, and the clamping plate 82 and the rubber pad 83 on the left move left together with the sliding rod 3, so as to be separated from the clamping of the Sophora japonica branch, and the Sophora japonica is collected into the container, so as to improve the collection efficiency.

[0027] When the Sophora japonica is collected, the collector holds the collection container with one hand and holds the collection device with the other hand, moves the collection device, places the Sophora japonica branch between the first cutting knife 2 and the second cutting knife 5, and then holds the handle 66 tightly. The handle 66 drives the sliding rod 3 to slide right through the second spur gear 65 and the first spur gear 62, the sliding rod 3 drives the clamping plate 82 and the rubber pad 83 on the left to move towards the housing 1, clamps and fixes the Sophora japonica branch, and then the Sophora japonica branch is cut by the first cutting knife 2 and the second cutting knife 5 which move towards the housing 1. Then the Sophora japonica which is cut and clamped is moved to the collection container, the handle 66 is loosened, the first spring 73 drives the sliding rod 3 to move left, and the clamping plate 82 and the rubber pad 83 on the left move left together with the sliding rod 3, so as to be separated from the clamping of the Sophora japonica branch, and the Sophora japonica is collected into the container.
