Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and particularly relates to a pepper picking device. Background Art

[0002] Sichuan pepper fruits are usually picked by hand or with scissors. This traditional method is relatively slow, and the short thorns on the Sichuan pepper trees can easily injure the picking workers during manual picking. Therefore, in order to avoid the above problems and improve the picking efficiency, various Sichuan pepper picking devices that can assist in picking Sichuan peppers have also appeared.

[0003] An existing pepper picking device includes a scissors handle for holding by hand, a fixed blade is arranged at the upper end of the scissors handle, a shearing blade is slidably arranged on the scissors handle and is provided with a handle that can drive the shearing blade to slide.

[0004] The above-mentioned pepper picking device slides the handle set on the scissors grip when picking, and when the handle drives the shearing blade to slide downward, the pepper located between the fixed blade and the shearing blade can be picked. The pepper picking device has a simple structure and is particularly convenient for picking low-lying peppers. However, because the length of the scissors grip is relatively short, the picker can only be used for picking peppers at the bottom of the pepper tree, and the pepper tree is generally 3-6 meters high. Therefore, the above-mentioned pepper picking device is not suitable for picking high-lying peppers. Although the peppers high on the tree can be touched by simply connecting a telescopic rod to the above-mentioned pepper picking device, the simple connection of the telescopic rod makes it impossible to control the opening and closing actions of the fixed blade and the shearing blade to pick the peppers. Therefore, it is necessary to improve the existing pepper picking device so that it can facilitate the picking of high-lying peppers. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0023] The Sichuan pepper tree is a deciduous small tree. The thorns on the trunk often fall off early, and the branches have short thorns. The Sichuan pepper fruits are usually picked by hand or cut with scissors. This traditional method of picking is relatively slow, and the short thorns on the Sichuan pepper tree can easily injure the picking workers during manual picking. Therefore, in order to avoid the above problems and improve the efficiency of picking, various Sichuan pepper picking devices that can assist in picking Sichuan peppers have also appeared.

[0024] An existing pepper picking device includes a scissors handle for holding by hand, a fixed blade is arranged at the upper end of the scissors handle, a shearing blade is slidably arranged on the scissors handle and is provided with a handle that can drive the shearing blade to slide.

[0025] The above-mentioned pepper picking device slides the handle set on the scissors grip when picking, and the handle drives the shear blade to slide downward to complete the picking action. Although this pepper picking device has a simple structure and is convenient for picking, because the distance between the picking handle and the shear blade is short, this picker can only be used for picking peppers at the bottom of the pepper tree, and the pepper tree is generally 3-6 meters high. Therefore, the above-mentioned pepper picking period is not suitable for picking peppers at high places. Therefore, it is necessary to develop a pepper picking device that is convenient for picking peppers at high places of pepper trees.

[0026] The invention discloses a pepper picking device, such as Figure 1-3 As shown, it includes: a supporting structure, a picking structure and a picking control structure, wherein the supporting structure includes a hollow mounting base plate and a multi-stage telescopic rod arranged on the upper side thereof; the picking structure includes a supporting plate, a fixed blade 4 and a shearing blade 18, the supporting plate 3 is vertically arranged at the upper end of the multi-stage telescopic rod 2, the fixed blade 4 is fixedly arranged on the supporting plate 3, and the shearing blade 18 is slidably connected to the supporting plate 3 and is located on the upper side of the fixed blade 4; the control structure includes a sliding plate 5, a first steel wire rope 6, a fixed handle 7, a compression handle 8 and a spring 9, the sliding plate 5 is slidably arranged on the mounting base plate 1 and can slide in the vertical direction, the fixed handle 7 is arranged on the mounting base plate 1, the compression handle 8 is hinged on the fixed handle 7, the spring 9 is located between the compression handle 8 and the spring 9, the lower end of the sliding plate 5 is connected to the compression handle 8, the lower end of the first steel wire rope 6 is connected to the upper end of the sliding plate 5, and the upper end of the first steel wire rope 6 is connected to the shearing blade 18.

[0027] Therefore, when the prickly ash picking device disclosed in the present invention is in use, the picker presses the compression handle 8 connected to the fixed handle 7, and then the compression handle overcomes the elastic force of the spring and drives the sliding plate 5 fixedly connected to the compression handle to slide downward, and while the sliding plate 5 slides downward, it acts on the shearing blade 18 through the first steel wire rope 6, so the shearing blade also starts to slide downward, and the prickly ash picking can be completed at this time. The present invention can realize the picking of prickly ash at a high place by providing a multi-stage telescopic rod 2 that can complete telescopic extension. When picking, the multi-stage telescopic rod 2 is first adjusted to an appropriate height, and then the prickly ash to be picked is clamped between the fixed blade 4 at the end and the shearing blade 18, and then the compression handle 8 is pressed to drive the sliding plate 5 and the first steel wire rope 6 to move, that is, the shearing blade 18 can slide to complete the shearing action. In summary, the present invention is very convenient and can realize the picking of prickly ash at a high place of a prickly ash tree.

[0028] Furthermore, in order to cooperate with the length change of the multi-stage telescopic rod 2, the length of the first steel wire rope 6 required when the multi-stage telescopic rod 2 is extended is extended, and the length of the first steel wire rope 6 required when the multi-stage telescopic rod 2 is shortened is shortened. Therefore, in order to make the length of the first steel wire rope 6 change with the length of the multi-stage telescopic rod 2, the sliding plate 5 disclosed in this embodiment is also provided with a first winding wheel 19, and the lower end of the first steel wire rope 6 is wound on the first winding wheel 19. Therefore, when the length of the multi-stage telescopic rod 2 changes, the length of the first steel wire rope 6 can be adjusted by the first winding wheel 19. Specifically, when adjusting the length of the first steel wire rope 6, the length of the first steel wire rope 6 can be matched and adjusted with the length of the multi-stage telescopic rod 2 manually or automatically. Specifically, the first winding wheel 19 can be controlled by a manual winding disk. Therefore, when the length of the multi-stage telescopic rod 2 changes, the winding disk can be manually rotated to make the first steel wire rope 6 match the length matching the multi-stage telescopic rod 2. Alternatively, according to the telescopic mode of the multi-stage telescopic rod 2, a structure that can realize transmission can be set between the multi-stage telescopic rod 2 and the first winding wheel 19. When the length of the multi-stage telescopic rod 2 changes, the length of the first steel wire rope 6 can be automatically extended or shortened.

[0029] Specifically, the multi-stage telescopic rod 2 disclosed in this embodiment includes a plurality of sleeves 20 that are sleeved in sequence, a horizontal fixing plate 10 is provided on the bottom surface of each sleeve 20, and a horizontal first supporting plate 11 is provided on the upper end surface of each sleeve 20 except the uppermost sleeve 20, and an opening corresponding to the first supporting plate 11 is provided on the side walls of all sleeves 20, one end of the first supporting plate 11 is located on the outside of all sleeves 20, and the other end of the first supporting plate 11 is located on the inner side of the most central sleeve 20, and the two ends of the first supporting plate 11 are respectively provided with vertical The mounting base plate 12 is provided with a second winding wheel 13 on each vertical plate 12, and a second steel wire rope 14 is provided between the two second winding wheels 13 on the same first support plate 11. A driving winding wheel 15 is also provided inside the mounting base plate 1. The outer end of the lowermost second winding wheel 13 passes through the side wall of the mounting base plate 1 and is wound on the driving winding wheel 15. The outer ends of the remaining second winding wheels 13 are fixedly connected to the corresponding vertical plates 12 located at the lower side, and the inner ends of all the second winding wheels 13 are fixedly connected to the fixing plate 10 on the upper sleeve 20. A motor is also provided inside the mounting base plate 1, and the driving winding wheel 15 is provided on the output shaft of the motor. Therefore, when the motor is working, it drives the active winding wheel 15 thereon to start rotating counterclockwise, and then the active winding wheel 15 starts to drive the second steel wire rope 14 wound thereon to move. When the second steel wire rope 14 moves, it drives a sleeve 20 of the second layer to start sliding upward. When the sleeve 20 of the second layer slides upward, the left side of a second steel wire rope 14 located on the sleeve 20 of the second layer becomes longer and the right side becomes shorter, so the third layer sleeve 20 connected to the right side end is also driven to slide upward, thereby completing the elongation process of the sleeve; a reset spring is also provided between two adjacent fixed plates 10, so when the length of the multi-stage telescopic rod 2 needs to be shortened, the motor is reversed, and then under the influence of the reset spring and the dead weight of the sleeve, the multi-stage telescopic rod 2 can be shortened or shortened to the required length.

[0030] The height of a Chinese prickly ash tree is generally between 3 and 6 meters, so three sleeves 20 are provided in this embodiment, which can generally meet the needs of picking Chinese prickly ash.

[0031] Therefore, when the length of the multi-stage telescopic rod 2 is extended or shortened, in order to allow the first steel wire rope 6 to be extended or shortened synchronously, a support shaft 16 parallel to the output shaft of the motor is further provided inside the mounting base plate 1 disclosed in the present embodiment, one end of the support shaft 16 sequentially passes through the side wall and the sliding plate 5 of the mounting base plate 1, and the first winding wheel 19 is provided on the support shaft 16, and a transmission gear set is provided between the output shaft of the motor and the support shaft 16; the specific transmission gear set includes a first gear provided on the output shaft of the motor, and a second gear meshing with the first gear is provided on the support shaft 16. When the motor drives the active winding wheel 15 to rotate counterclockwise, the multi-stage telescopic rod 2 is extended or shortened. The length of the retractable rod 2 is extended, and the first gear arranged on the motor output shaft rotates counterclockwise, and the second gear arranged on the support shaft 16 rotates clockwise, and then the first winding wheel 19 on the support shaft rotates clockwise, so the first steel wire rope 6 wound on the first winding wheel 19 is also extended; similarly, when the motor drives the active winding wheel 15 to rotate clockwise, the length of the multi-stage telescopic rod 2 is shortened, and the first gear arranged on the motor output shaft rotates clockwise, and the second gear arranged on the support shaft 16 rotates counterclockwise, and then the first winding wheel 19 on the support shaft rotates counterclockwise, so the first steel wire rope 6 wound on the first winding wheel 19 is also shortened.

[0032] Furthermore, the pepper picking device disclosed in the present embodiment also includes a storage basket 17, and the mounting base plate 1 can be detachably mounted on the side wall of the storage basket 17, and a universal wheel is also provided at the bottom of the storage basket 17; when picking, the mounting base plate 1 can be directly mounted on the storage basket 17, or the mounting base plate 1 can be removed from the storage basket 17 and the entire picking structure can be lifted from the control handle at the bottom for picking; a pepper guide sleeve 21 is also provided on the outer side of the support plate 3, and the upper end of the pepper guide sleeve 21 is fixed to the support plate 3 by a support ring 22, and a guide frame facing the top is provided on the support ring 22, and the guide frame is made of soft plastic or silicon The pickled peppercorns are made of a rubber material and can prevent the pickled peppercorns from falling. After being guided by the guide frame, the pickled peppercorns can smoothly fall into the peppercorn guide sleeve 21. The bottom of the peppercorn guide sleeve 21 is also provided with a tightening rope that can seal the bottom of the peppercorn guide sleeve 21. Therefore, when the entire picking structure is lifted for picking, the bottom of the entire peppercorn guide sleeve 21 can be sealed by tightening the rope, and then the picked peppercorns will fall into the peppercorn guide sleeve 21. When the mounting base plate 1 is installed on the storage basket 17 for picking, the bottom of the peppercorn guide sleeve 21 can be opened, so that the picked peppercorns can directly fall into the storage basket 17 after passing through the bottom of the peppercorn guide sleeve 21.

[0033] In summary, when the pepper picking device disclosed in the present invention is used, the picker presses the compression handle 8 connected to the fixed handle 7, and then the compression handle overcomes the elastic force of the spring to drive the sliding plate 5 fixedly connected to the compression handle to slide downward, and while the sliding plate 5 slides downward, it acts on the shearing blade 18 through the first steel wire rope 6, so that the shearing blade also starts to slide downward, and the picking of pepper can be completed at this time. The present invention can realize the picking of high-place pepper by providing a multi-stage telescopic rod 2 that can complete telescopic extension. When picking, the multi-stage telescopic rod 2 is first adjusted to an appropriate height, and then the pepper to be picked is clamped between the fixed blade 4 and the shearing blade 18 at the end, and then the compression handle 8 is pressed to drive the sliding plate 5 and the first steel wire rope 6 to move, that is, the shearing blade 18 can slide to complete the shearing action, and when the length of the multi-stage telescopic rod 2 changes, the length of the first steel wire rope 6 can be automatically matched to the length matching the multi-stage telescopic rod 2. In summary, after the present invention completes picking through the cooperation of the fixed blade 4 and the shear blade 18, the fallen peppercorns are guided by the guide sleeve 21 and finally fall into the storage basket 17 at the bottom. During actual picking, the entire picking device can be pushed as a whole to move to different positions at the bottom of the pepper tree to pick the peppercorns at high places.

[0034] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention belong to the protection scope of the present invention.
