Description

Technical Field

[0001] The invention relates to the technical field of fruit picking devices, in particular to a winter jujube picking, collecting, impurity removal and sorting system. Background Art

[0002] The picking process of winter jujube is divided into manual collection and tool collection. The winter jujube with lower height can be picked directly by hand, while the winter jujube with higher height needs to be picked off the tree by holding a long pole. This process is not only cumbersome, time-consuming and labor-intensive, but also has low picking efficiency. At the same time, the winter jujube will fall to the ground by using a long pole or climbing a tree, affecting its quality.

[0003] At present, conventional picking tools are equipped with a collecting basket so that the picked winter jujubes can fall directly into the collecting basket to avoid falling on the ground. However, when picking winter jujubes at a high height, it is inevitable that leaves or branches on one side will fall into the collecting basket during the picking process. After the picking is completed, the leaves, branches and other debris in the collecting basket need to be removed, which is inconvenient. Summary of the invention

[0015] Beneficial effects of the present invention:

[0016] 1. In the present invention, when the first push plate moves toward the first row of outlets, the connecting rod pushes the blocking cloth back, and at this time the first sliding block slides upward along the sliding rail, and in the absence of the traction of the pull rope, the sliding frame and the pressing frame move downward along the vertical plate through the elastic force of the first spring, and squeeze the larger leaves or branches on the fruit entry plate until the vertical edge of the pressing frame contacts the fruit entry plate. Before the first push plate moves to the fruit entry plate, it will contact the back side of the pressing frame through the push rod, so that the pressing frame slides along the sliding frames on both sides, and the flattened leaves and branches are pushed out from the first row of outlets, thereby repeating the delivery of leaves and branches in the corresponding picking process.

[0017] 2. In the present invention, the blocking cloth is unwound by the reel through the traction of the connecting rod, so as to block the upper end of the fruit feeding plate and guide the picked winter jujubes to fall on the front end of the first push plate, thereby preventing leaves and twigs from falling directly into the mesh bag through the through holes. When the first push plate is pushed along the surface of the collecting box, the blocking cloth is gradually reeled in to allow the winter jujubes to be delivered into the lower mesh bag. In this process, the first push plate also serves to prevent blockage during the top cleaning of the corresponding collecting box.

[0018] 3. The present invention drives two first gears to rotate and mesh through a small motor, and the two clamping frames perform opening and closing movements. Accompanied by manual downward pulling, the winter jujube can be picked from the tree branch, which can reduce the length of the branches carried by the rear end of the winter jujube. The inner side of the clamping frame can also be replaced with scissors, and the winter jujube can be picked by shearing. During the rotation of the first gear, the shaft drives the second gear to rotate, and the two tooth plates mesh with the second gear to drive the extension plate to slide along the moving notch, so that the first push plate and the second push plate move synchronously to clean the top and the inside of the collecting box respectively. The leakage groove is used to receive smaller debris and is sent out from the second discharge outlet by the second push plate. The first push plate pushes the winter jujube to the side of the fruit inlet plate. This process is synchronized with the picking of the winter jujube to improve efficiency.

[0019] 4. Compared with the prior art, the present invention, through the cooperation of the picking component and the sorting component, after each picking action is completed, the winter jujubes in the collection frame move along the collection box and the fruit feeding plate until they fall into the bottom mesh bag, among which the larger leaves, smaller leaves and branches will be collected separately, reducing the amount of debris mixed into the winter jujubes and reducing the difficulty of later impurity removal.

The two first gears 56 are driven by the small motor 55 to rotate and mesh, and the two clamping frames 51 are opened and closed. With the artificial downward pull, the winter jujube can be picked from the branch, which can reduce the length of the support rod carried by the rear end of the winter jujube. The inner side of the clamping frame 51 can also be replaced with scissors to pick the winter jujube by cutting. During the rotation of the first gear 56, the shaft 57 drives the second gear 58 to rotate, and the two tooth plates 59 are meshed with the second gear 58 to drive the extension plate 37 to slide along the moving notch 36, so that the first push plate 44 and the second push plate 49 move synchronously, and the top and the inside of the collecting box 47 are cleaned respectively. The leakage groove 48 is used to receive smaller debris and is sent out from the second discharge port 35 by the second push plate 49. The first push plate 44 pushes the winter jujube to move to the side of the fruit inlet plate 410. This process is synchronized with the picking of the winter jujube to improve efficiency.

[0034] In this embodiment, inclined slide rails 42 are fixed on the inner walls of both sides of the top of the collection frame 3, and the first sliders 413 are slidably connected inside the slide rails 42, and a cloth blocking 41 is fixed between the two first sliders 413. A reel 43 is rotatably installed on the top edge of the collection frame 3 through a bearing and a torsion spring, and the cloth blocking 41 is rolled up on the reel 43. Connecting rods 46 are rotatably installed on both sides of the first push plate 44 through a rotating shaft, and the other end of the connecting rod 46 is rotatably connected to the front end of the cloth blocking 41 through a rotating shaft. In the picking state, the first push plate 44 is located in the collection frame 3, the blocking cloth 41 is unwound by the reel 43 through the traction of the connecting rod 46, and the upper end of the fruit feeding plate 410 is blocked, and the picked winter jujubes are guided to fall on the front end of the first push plate 44, so as to prevent leaves and branches from directly falling into the net bag 32 through the through hole 412. When the first push plate 44 is pushed along the surface of the collecting box 47, the blocking cloth 41 is gradually rolled up to allow the winter jujubes to be delivered to the lower net bag 32. In this process, the first push plate 44 also plays a role in the top cleaning of the corresponding collecting box 47 to prevent blockage.

[0035] In this embodiment, the collecting frame 3 is provided with a pressing frame 411 at the top of the first discharge port 34, and the collecting frame 3 is fixed with vertical plates 415 on the inner walls of both sides of the pressing frame 411, and a sliding frame 416 is slidably installed on the surface of the vertical plate 415, and the inner wall of the sliding frame 416 is slidably connected with a second slider 419, and the second slider 419 is fixedly connected to the pressing frame 411, and a second spring 418 is fixed inside the sliding frame 416, and the other end of the second spring 418 is fixedly connected to the second slider 419, and the two sides of the first push plate 44 are fixed with a push rod 4 5, and the push rod 45 is pressed and contacted with the pressing frame 411 after the first push plate 44 moves, the first spring 417 is provided on both sides of the vertical plate 415, and the two ends of the second spring 418 are fixedly connected to the sliding frame 416 and the sliding rail 42, and a pull rope 414 is provided inside the sliding rail 42, one end of the pull rope 414 is fixedly connected to the first sliding block 413, and the other end of the pull rope 414 passes through the sliding rail 42 and is fixedly connected to the sliding frame 416, and the pressing frame 411 is a right-angled frame, which can move in the horizontal and vertical directions under the guidance of the sliding frame 416 and the vertical plate 415 When the blocking cloth 41 is fully unfolded, the first sliding block 413 is located at the bottom of the slide rail 42. At this time, the pull rope 414 pulls the sliding frame 416 to move to the top of the vertical plate 415, and the pressing frame 411 does not block the first row outlet 34. At this time, during the picking process, the leaves remaining on the top of the collection box 47 and the fruit inlet plate 410 can be shaken out from the first row outlet 34 by shaking. When the first push plate 44 moves toward the first row outlet 34, the connecting rod 46 pushes the blocking cloth 41 back. At this time, the first sliding block 413 slides upward along the slide rail 42. When there is no pull rope 414 Under the traction of the first spring 417, the sliding frame 416 and the pressing frame 411 move downward along the vertical plate 415 to squeeze the larger leaves or branches on the fruit entry plate 410 until the vertical edge of the pressing frame 411 contacts the fruit entry plate 410. Before moving to the fruit entry plate 410, the first push plate 44 will be squeezed and contacted with the back side of the pressing frame 411 through the push rod 45, so that the pressing frame 411 slides along the sliding frames 416 on both sides, and the flattened leaves and branches are pushed out from the first outlet 34, thereby repeating the delivery of leaves and branches in the corresponding picking process.

[0036] When the device is used, the height of the picking component 5 is controlled by the electric push rod 1, and the two first gears 56 are driven to rotate and mesh by the small motor 55, and the two clamping frames 51 are opened and closed. With the artificial downward pull, the winter jujube can be picked from the branch, which can reduce the length of the support rod carried by the rear end of the winter jujube. The inner side of the clamping frame 51 can also be replaced with scissors to pick the winter jujube by cutting. During the rotation of the first gear 56, the shaft 57 drives the second gear 58 to rotate, and the two tooth plates 59 are engaged with the second gear 58 to drive the extension plate 37 to slide along the moving notch 36, so that the first push plate 44 and the second push plate 49 move synchronously, respectively pressing the top and inner part of the collecting box 47. The first push plate 44 pushes the winter jujube to move to the side of the fruit inlet plate 410. This process is synchronized with the picking of the winter jujube to improve efficiency. In the picking state, the first push plate 44 is located on the side of the collection frame 3 away from the first outlet 34. Through the traction of the connecting rod 46, the blocking cloth 41 is unwound by the reel 43 to block the upper end of the fruit inlet plate 410 and guide the picked winter jujube to fall on the front end of the first push plate 44 to prevent leaves and branches from falling directly into the net bag 32 through the through hole 412. During the pushing process of the first push plate 44 along the surface of the collection box 47, the blocking cloth 4 1 is gradually rolled up for the winter jujube to be sent into the lower net bag 32. In this process, the first push plate 44 also plays a role in the top cleaning process of the corresponding collection box 47 to prevent blockage. When the blocking cloth 41 is fully unfolded, the first slider 413 is located at the bottom of the slide rail 42. At this time, the pull rope 414 pulls the slide frame 416 to move to the top of the vertical plate 415, and the pressing frame 411 will not block the first row outlet 34. At this time, during the picking process, the leaves remaining on the top of the collection box 47 and the fruit feeding plate 410 can be shaken out from the first row outlet 34 by shaking. When the first push plate 44 moves toward the first row outlet 34, the connecting rod 46 pushes the blocking cloth 41 back. At this time, the first slider 413 moves upward along the slide rail 42. Sliding, without the traction of the pull rope 414, through the elastic force of the first spring 417, the sliding frame 416 and the pressing frame 411 move downward along the vertical plate 415, squeezing the larger leaves or branches on the fruit entry plate 410 until the vertical edge of the pressing frame 411 contacts the fruit entry plate 410. Before moving to the fruit entry plate 410, the first push plate 44 will be squeezed and contacted with the back of the pressing frame 411 through the top rod 45, so that the pressing frame 411 slides along the sliding frames 416 on both sides, and the flattened leaves and branches are pushed out from the first outlet 34, thereby repeating the delivery of leaves and branches in the corresponding picking process. After the net bag 32 is full, the net bag 32 can be removed through the zipper lock 33, and the winter jujubes can be poured out.
