Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more particularly to a parallel clamping automatic mulberry harvesting device. Background Technology

[0002] Currently, mulberry leaf harvesting mainly relies on manual labor, which is labor-intensive, time-consuming, and inefficient. Therefore, automated mulberry leaf harvesting is particularly important, and improving the efficiency and quality of mulberry leaf harvesting has become a problem that the sericulture industry needs to solve.

[0003] Chinese invention patent application CN117999956B discloses a cutting mulberry leaf picking device. Its moving blade can rotate at a certain angle relative to the fixed blade to cut the mulberry leaf stalk. The mulberry leaves fall into the collection devices on both sides. However, the following defects still exist in the use: (1) When the lifting platform is raised, there will be blank areas of mulberry leaves that are not cut when the moving blade rotates to cut, resulting in the mulberry leaves not being completely picked. (2) The height of the front end of the middle rod is inconsistent with that of the left and right rods, and the inlet and outlet of the mulberry branch cutting is too small. As a result, the mulberry branches will be bent when they are clamped by the middle rod and the left and right rods before they enter the cutting channel. Summary of the Invention

[0004] In order to solve one of the technical problems mentioned in the background, the present invention aims to provide a parallel clamping automatic mulberry picking device, which is highly feasible and can realize the picking and collection of multiple mulberry branches from a single mulberry tree at one time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The clamping assembly includes a pair of first slide rails respectively located on the front and rear sides above the lifting platform and arranged in the left and right directions; a pair of connecting blocks respectively fixed in the middle section of the two first slide rails; four first sliders respectively slidably disposed in the two first slide rails and respectively placed on the left and right sides of the corresponding connecting blocks; a middle positioning plate arranged horizontally in the front and rear directions and fixedly connected to the upper side of the two connecting blocks respectively; a pair of clamping plates arranged horizontally in the front and rear directions and respectively located on the left and right sides of the middle positioning plate and fixedly connected to the two first sliders on the same side; a synchronous belt drive mechanism disposed between the two first slide rails; a pair of synchronous belt toothed plates respectively fixed on the front and rear sides of the synchronous belt in the synchronous belt drive mechanism and used to adjust the distance between the two clamping plates; and a drive motor disposed below the lifting platform and axially fixedly connected to the left drive wheel in the synchronous belt drive mechanism.

[0008] The two synchronous belt toothed plates are respectively disposed on the left and right sides of the synchronous belt drive mechanism, and the synchronous belt toothed plates are fixedly connected to the lower part of the corresponding side clamping plates.

[0009] As a further improvement to the above technical solution:

[0010] Each harvesting assembly includes several first semi-wrapping slots arranged at intervals along the front-back direction on the corresponding sides of the intermediate positioning plate, multiple second semi-wrapping slots corresponding one-to-one with each of the first semi-wrapping slots on the corresponding clamping plates, multiple semi-circular blades fixed to the upper side of each of the first and second semi-wrapping slots, multiple first blocks fixed to the corresponding sides of the intermediate positioning plate and located between two first semi-wrapping slots, multiple second blocks fixed to the side walls of the corresponding clamping plates and located between two second semi-wrapping slots, and multiple anti-collision blocks fixed to the first and second semi-wrapping slots.

[0011] More preferably, the collecting assembly includes a collecting frame fixed to the side of the corresponding clamping plate away from the intermediate positioning plate, a collecting plate hinged to the collecting frame on the lower side of the collecting frame away from the clamping plate, a rotating plate fixed to the rear end of the collecting plate, an electric push rod fixed to the upper rear side of the corresponding clamping plate and arranged in the left-right direction, and a rotating rod fixed to the output end of the electric push rod and movably embedded in the rotating plate.

[0012] More preferably, the lifting assembly includes a screw rotatably disposed on the front side of the frame and arranged along the vertical direction of the frame, a sliding seat threadedly sleeved on the screw along the vertical direction of the frame, a rotating motor disposed above the frame and whose output shaft is axially fixedly connected to the screw, a pair of second slide rails respectively disposed on the left and right sides of the front of the frame and arranged along the vertical direction of the frame, and two sets of sliders respectively slidably disposed in the second slide rails on both sides.

[0013] The sliding seat is fixedly connected to the rear side of the lifting platform. Each group of sliders includes two second sliders arranged vertically at intervals in the corresponding second slide rail. Each second slider is fixedly connected to the corresponding rear side of the lifting platform.

[0014] More preferably, the clamping plate has an arc-shaped end at its front end, a first baffle is fixedly provided on the upper side of the front end of the clamping plate, the intermediate positioning plate has an arc-shaped end at its front end, and a second baffle is fixedly provided on the upper side of the front end of the intermediate positioning plate.

[0016] More preferably, a pair of limiting grooves are provided on the left and right sides below the frame, respectively arranged in the front and rear directions, and a pair of limiting blocks are fixed on the top of the base, respectively embedded in the corresponding limiting grooves.

[0017] The present invention has the following beneficial effects.

[0018] 1. When the above-mentioned parallel clamping components are opened, the clamping distance is wide. The clamping plate cooperates with the arc-shaped branch-pulling plate under the middle positioning plate, leaving enough space and time for several mulberry branches to enter the clamping opening, thus avoiding the mulberry branches failing to enter the clamping opening and resulting in the mulberry leaves being missed.

[0019] 2. The above-mentioned picking component uses a semi-circular arc blade. When the clamping plate and the middle positioning plate are closed, a complete cutting and wrapping groove is formed. In conjunction with the lifting mechanism, the mulberry leaves can be picked from all directions.

[0020] 3. The collection plate in the above-mentioned collection components can be flipped by an electric push rod, which facilitates the transfer and bagging of the harvested mulberry leaves without the need for manual collection. Attached Figure Description
