Description

Seedling picker for vegetable transplanter

technical field

The invention relates to a clamping device, in particular to a seedling picking clamp for a vegetable transplanter, and belongs to the technical field of agricultural and forestry machinery.

Background technique

As far as the applicant knows, the existing vegetable transplanting machines all need to manually take the seedlings and then feed the seedlings. For example, in the technical solutions disclosed in Chinese patents with publication numbers CN204119785U and CN204217400U, the vegetable transplanting machines are semi-automatically operated and need to be completed manually. Taking seedlings and feeding seedlings is not only labor-intensive, but also has extremely low transplanting efficiency. In addition, rising labor costs have led to an increase in vegetable production costs.

Since seedling picking not only needs to complete shifting and picking, the action is complex, but also requires strong adaptability and precision, which has become a bottleneck in the research and development of vegetable transplanters.

Contents of the invention

The purpose of the present invention is to: propose a kind of vegetable transplanting machine seedling picking clip that has simple structure, can effectively replace manual seedling picking and arranging action, thereby lays the foundation for designing and manufacturing the vegetable transplanting machine of automatic seedling picking.

In order to achieve the above object, the basic technical solution of the seedling picking clip for vegetable transplanting machine of the present invention is as follows: it includes a seedling fork seat with a front fork and a rear fork, and a fork for adjusting the distance between the fork Longitudinal jacking bolts, the upper and lower sides of the seedling fork seat have a pair of seedling fork handles respectively, the front ends of the seedling fork handles are connected with the front ends of the seedling fork seat to form a clamping seam that opens toward the rear, and the clamping seam Elastic parts are housed between the rear ends of the forks, and the seedling forks extending forward are fixed on the handles of the seedling forks, and horizontal butt bolts for adjusting the opening distance of the seedling forks are installed between the adjacent two handles of the seedling forks.

Further, the rear fork bottom of the seedling fork seat has an extension slot, and auxiliary seam adjustment bolts are installed in the extension slot. In particular, the bottom of the extension slit forms an arc bottom with an enlarged diameter.

Furthermore, the front end of the seedling fork handle is connected with the front end of the seedling fork seat through an arc bend.

Still further, the position of the seedling fork seat corresponding to the rear end of the clamping slit has an inlay claw forming an arc groove, and the inlay claw is embedded with a silicone profile as an elastic member.

Still further, the silicone profile has an elastic tube that fills the clamping seam.

After the seedling picking clip of the present invention is installed on the seedling picking mechanism, the distance between the up and down, left, and right sides of the seedling picking fork can be conveniently adjusted according to the size of the seedling trays of different specifications, and the displacement movement of the seedling picking mechanism and the addition of the seedling picking handle can be used to facilitate adjustment. Pressure control, realize the automatic opening and closing movement of the seedling fork, automatically complete the removal of seedlings in the seedling tray and discharge after displacement, greatly reduce labor intensity, improve work efficiency, and properly solve the bottleneck problem of vegetable transplanter design.

detailed description

As shown in Figures 1, 2 and 3, the vegetable transplanting machine of the present embodiment includes a seedling fork seat 3 with a jaw-like front fork 1 and a rear fork 2. Between the front forks 1 of the seedling fork seat 3, the vertical butt bolts 4 for adjusting the spacing of the forks are arranged. The rear fork 2 bottom of seedling fork seat 3 has the extension seam 2-1 at the bottom of the circular arc with expanding diameter, and auxiliary seam adjustment bolt 11 is housed in the extension seam 2-1. Therefore, 4 and 11 can be adjusted conveniently and reliably, and the purpose of adjusting the distance between the front ends of the up and down seedling forks 9 can be achieved by changing the distance between the forks.

The upper and lower sides of the seedling fork seat 3 respectively have a pair of bent slat-shaped seedling fork handles 5, and the front ends of the seedling fork handles 5 and the front ends of the seedling fork seat 3 are connected by arc bends to form a clamping seam 6 that opens toward the rear. . So that the whole becomes a symmetrical shape like the upper and lower sides of M.

The seedling fork seat 3 has an inlaid claw 7 that forms an arc groove at the position corresponding to the rear end of the clamping seam 6 . The inlaid claw is embedded with a silicone profile 8 , and the silicone profile 8 has an elastic tube 8 - 1 that fills the clamping seam 6 .

The seedling fork handle 5 is fixed with the seedling fork 9 extending forward, and the seedling fork handle 5 has a front tip. A horizontal buttress bolt 10 for adjusting the distance between the forks of the seedlings is installed between two adjacent fork handles 5 of the seedlings. The purpose of adjusting the distance between the front ends of the left and right seedling forks 9 can be achieved by changing the distance between the handles of the seedling forks by means of the horizontal counterbolts 10 .

During use, after the seedling picking clip of the present embodiment is installed on the seedling picking mechanism, according to the size of seedling trays of different specifications, adjust the spacing of the seedling picking fork up, down, left, and right.

When the seedling picking mechanism drives the seedling picking clip close to the seedling tray, the seedling picking handle gradually contacts with the fixing part (curved L plate) on the frame to overcome the elastic force of the silicone profile, so that the seedling picking fork is opened up and down and inserted into the seedling tray to align with the corresponding Hole seedlings. Then, the seedling-taking handle is released, and the silica gel profiles are reset to make the seedling-taking fork close to clamp the hole seedlings, and then return. When reaching the seedling row position, get the seedling fork to open again with the aforementioned same principle, and the hole seedlings fall in the rear stage container (triangular seedling planter). Finally, the seedling-taking clip is returned to its position, and the next cycle of seedling-taking and seedling-discharging is entered.

Practice has proved that the seedling picking clip of the present embodiment has the following significant advantages:

1. Reasonable design and convenient adjustment - by conveniently adjusting a pair of horizontal top bolts and vertical top bolts, the spatial position of the four seedling forks can be changed, and the clamping of Q21, Q32, Q50, Q72, Q98, and Q128 can be realized. And other standard seedling trays and seedlings in non-standard seedling trays.

2. Reliable clamping and release - when picking seedlings, the silicone material on one side of the seedling picking clamp is under pressure, corresponding to the opening angle of the two seedling picking forks relative to the original position, ensuring that the seedling picking forks are accurately inserted into the seedling tray and will not exceed the hole tray; When the silicone profile is not under pressure, the silicone profile resets, and the four seedling forks automatically clamp the hole seedlings. The clamping force ensures that the hole seedlings will not fall off midway; The seedling picking fork is opened at an angle relative to the original position, and the clamping force of the seedling picking clip on the hole seedling is almost zero, so it is ensured that the hole seedling falls off under the action of gravity.

3. Good workmanship and ingenious elastic structure - the seedling picking clip can be made of high-strength plastic material, which is convenient to make, and the required elastic deformation can be produced in the horizontal and vertical directions without plastic deformation, ensuring the long-term stability of the seedling picking clip Work.

4. Exquisite shape design and compact structure - vertical and horizontal elastic deformation and other functions are integrated into one, and silicone profile grooves, horizontal and vertical jacking bolts, splits, etc. are set at appropriate positions.
