Description

A kind of pot seedling transplanting machine rapid automatic seedling picking and throwing device

technical field

The invention relates to a device for quickly and automatically taking seedlings and throwing seedlings for a pot seedling transplanting machine, which belongs to the field of agricultural machinery and equipment.

Background technique

In the production of feed mulberry, vegetables, cotton, tobacco and other crops that require seedling cultivation, seedling transplanting is an essential process. At present, most of the transplanting machines used in my country can complete ditching, fertilization, transplanting, and soil cultivation at one time. , watering and other processes, and can make the transplanting plant spacing uniform, the pot seedling planting depth basically the same, the seedlings upright, the missed planting rate is low but the survival rate is improved, so the use of the transplanting machine has greatly reduced the farmers' labor costs. labor intensity, increased transplanting efficiency and improved seedling production conditions. However, at present, the transplanting machines used in our country are almost all semi-mechanized operations, that is, during the transplanting process, a special seedling operator is required to continuously take out the seedlings from the seedling tray and then put them into the horizontally rotating feeder of the transplanting machine. The working environment in the field is relatively harsh, such as uneven ground, uncertain wind speed and direction in the field, and uneven working speed of the transplanting machine, etc. The difficulty, the working conditions are very bad, the labor intensity is high, and the transplanting efficiency is low, which is obviously contrary to the agronomic requirements. In addition, because the seedling throwing speed of the seedling throwers is not high, according to statistics, the feeding speed of ordinary farmers does not exceed 60 plants/min, which limits the transplanting speed of the transplanting machine to a large extent, and cannot achieve fast speed. Efficient transplanting of pot seedlings results in labor-intensive and time-consuming pot seedling transplanting procedures, low transplanting efficiency, and failure to meet agronomic requirements. Otherwise, seedling shortage and missing seedlings will occur easily because the speed of the seedling thrower feeding the pot seedlings is too slow to keep up with the operating speed of the transplanting machine, and the transplanting quality of the tobacco seedlings cannot be well guaranteed.

Therefore, the realization of the automatic seedling picking function of the transplanting machine, that is, the automatic transplanting machine, has high practical value, can meet the agronomic requirements to a large extent, has a good market prospect, and can effectively liberate manpower and reduce The amount of labor of farmers, improving transplanting efficiency and ensuring transplanting quality, reducing the cost of seedling planting, can achieve the purpose of increasing production and income, and can promote the development of agricultural production to a certain extent.

Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

A device for quickly and automatically taking seedlings and throwing seedlings for pot seedling transplanting machines, which is composed of seedling clips, a rotating mechanism, rails, etc. 7 is clamped with connecting rod five 11 and can move freely; the lower seedling clip 10 is clamped by connecting rod four 8 and connecting rod six 12 and can move freely; connecting rod three 7, connecting rod five 11, and upper seedling clip 9 , axis three 21 and axis four 22 form a parallelogram structure; connecting rod four 8, connecting rod six 12, upper seedling clip 10, axis one 19 and axis two 20 form a parallelogram structure; connecting rod two 6 connect connecting rod three 7 and Double rocker 5, connecting rod 1 4 connects connecting rod 4 8 and double rocker 5; connecting rod 3 7 can rotate around axis 4 22, connecting rod 4 8 can rotate around axis 19, connecting rod 5 11 can rotate around axis 3 21 rotates, and connecting rod six 12 can rotate around axle two 20.

Double rocker 5, shaft one 19, shaft two 20, shaft three 21, and shaft four 22 are respectively supported by support plate one 3 and support plate two 13, and can rotate freely; support plate one 3 and support plate two 13 are supported by push rods One 14 and push rod two 16 support and promote simultaneously; the two ends of push rod one 14 and push rod two 16 are fixed in the linear guide rail one 2 and linear guide rail two 15 through bearings, and do linear motion forward and backward in the linear guide rail.

Power is provided by power input shaft 17, and power input shaft 17 connects push rod two 16.

The power input shaft 17 moves forward. When the blocking shaft 25 moves to the front end 23 of the first rotation control guide rail, the power input shaft 17 continues to move forward. Because it is blocked, the double rocker 5 rotates counterclockwise, and the connecting rod 2 6 drives the connecting rod 17 to move forward. Rod three 7 rotates clockwise, while upper seedling clip 9 moves to the right; connecting rod one 4 drives connecting rod four 8 to rotate counterclockwise, while lower seedling clip 10 moves left, thereby realizing the clamping action.

The power input shaft 17 moves backward. When the blocking shaft 25 moves to the first rear end 24 of the rotation control guide rail, the power input shaft 17 continues to move backward. Due to being blocked, the double rocker 5 rotates clockwise, and the connecting rod 2 6 drives The connecting rod three 7 rotates counterclockwise, and the upper seedling clip 9 moves to the left at the same time;

During specific use, the logarithm of seedling clips is determined by the size of the tray (i.e. the number of seedlings per row). The logarithm of seedling clips designed in the present invention is 8 pairs, which can pull out 8 seedlings at a time. For a tray of 8 trees in a row, the size of the seedling clip is determined according to the size of the seedlings.

The power input shaft 17 moves forward, and the seedling clamp completes the clamping action. Then, the power input shaft 17 moves backward, so that the seedlings are pulled out under the action of the clamping force, that is, the stage of pulling out the seedlings; the power input shaft 17 continues to move backward. Complete the seedling transportation, that is, the seedling transportation stage; the power input shaft 17 continues to move backward, and the seedling clamp completes the loosening action, that is, the seedling falling stage; then, the power input shaft 17 moves forward, thereby completing the return stage. Such reciprocating motion realizes the continuous seedling taking, transporting seedlings, falling seedlings and return journey of the invention.
