Description

Technical Field

[0001] The invention relates to an agricultural picking device, in particular to a high-efficiency and lossless honeysuckle picking device, belonging to the technical field of agricultural machinery equipment. Background Art

[0002] Honeysuckle, also known as honeysuckle, is a commonly used Chinese medicine with a long history and is widely planted in my country. The buds of honeysuckle are rod-shaped, thick on the top and thin on the bottom. The peduncle is usually solitary in the leaf axils of the upper part of the twigs, and is the same length as the petiole or slightly shorter. Because honeysuckle and leaves grow together, it is not conducive to centralized picking. It is generally picked by hand, which has low picking efficiency and high labor intensity. Because the picking window of honeysuckle is short, untimely picking will cause the medicinal value of honeysuckle to decrease. The currently published honeysuckle picking equipment has problems such as high picking flower injury rate and unsatisfactory picking effect. There is an urgent need for an efficient and lossless honeysuckle picking device that can ensure both timely picking of honeysuckle and the quality of honeysuckle picking. Summary of the invention

[0033] like Figure 4As shown, in this embodiment, in order to prevent the shift lever shaft 6 from rotating, the cross-sections at both ends of the shift lever shaft 6 are D-shaped, and the number is 2, which respectively pass through the D-shaped holes of the two shift lever shaft seats 5 on the same vertical plane of the Z-shaped structure of the main shaft 2, and the axis of the shift lever shaft 6 is parallel to the axis of the main shaft 2; one end of the shift lever shaft 6 is connected to the top rod head 4; a row of N (in this embodiment, N=15) equidistant shift lever mounting holes 61 are opened in the middle part of the shift lever shaft 6.

[0036] In order to provide effective rotational torque, the shift block 8 is an L-shaped structure. The lower horizontal line part is cylindrical with a through hole in the middle, which matches the position of the hilt 912 of the comb teeth 9; the cross-section of the vertical line part is a rectangle, and after installation, the upper part of its side is tangent to the optical axis of the shift rod 7.

[0037] like Figure 7 and Figure 8 As shown, in this embodiment, in order to reduce the jamming and other phenomena caused by the friction of the device, the push rod head 4 is structured as a ball head at one end, a thread at the other end, and a shoulder in the middle; the push rod head 4 is fixed to the lever shaft 6 through a thread; the compression spring 11 is installed between the lever shaft seat 5 and the shoulder of the push rod head 4; the ball head of the push rod head is tangent to the outer end surface 31 of the cam plate 3. When working, the push rod head 4 makes a circular motion on the outer end surface 31 of the cam plate 3, and drives the lever shaft 6 to make a reciprocating motion through the outer end surface 31 of the cam plate 3 and the compression spring 11.

[0040] When the device of the present invention is working, the driving motor drives the main shaft 2 to rotate, driving the two rows of comb teeth 9 to pick and transport the honeysuckle in turn. Two lever shafts 6 are fixed on the main shaft, and the levers 7 are fixed on the lever shafts 6 in turn, corresponding to the shifting blocks 8 one by one. The shifting blocks 8 and the comb teeth 9 correspond to each other one by one and are fixed together. One end of the lever shaft 6 is connected to the push rod head 4, and the ball head of the push rod head 4 is tangent to the outer end surface 31 of the cam disk 3 and is compressed by the compression spring 11. When the main shaft 2 rotates, the cam disk 3 will push the lever shaft 6 to perform axial reciprocating motion. The lever shaft 6 drives the lever 7 to shift the shifting blocks 8 through the axial reciprocating motion, so that the shifting blocks 8 rotate around the axis of the comb teeth 9, thereby rotating the comb teeth 9. When the main shaft 2 rotates continuously, the cam plate 3 pushes the lever shaft 6 to make uninterrupted axial reciprocating motion, so that the comb teeth 9 swing 90 degrees around the axis of the comb tooth mounting holes 21 that match each other, and realize the action process of the outline spacing between adjacent comb teeth 9 from large to small to large, thereby realizing the teeth insertion, clamping, and release of the honeysuckle. When the rotating comb teeth 9 clamp the honeysuckle, the honeysuckle is picked by its own rotation.
