Description

Technical field:

[0001] The invention relates to the technical field of garlic sowing equipment, and in particular to a garlic sowing device and method with a smaller plant spacing. Background technology:

[0002] At present, garlic sowing technology is relatively mature, and agricultural mechanized equipment is mainly used to complete sowing. For example, the company previously disclosed a garlic sowing machine (authorization announcement number: CN 107124923 B), which has the functions of rotary tillage, seed collection, planting and sowing, and suppression, and the mechanization and integration are significantly improved. The planting mechanism disclosed in the invention mainly based on the duckbill structure can realize the upright planting of garlic seeds, and the positive bud rate is high.

[0003] Although the above-mentioned planting mechanism can significantly improve the positive bud rate, due to the limitations of its structure and working principle, the minimum sowing spacing of the existing garlic seeder is 9 cm. However, in actual sowing, the requirement for the spacing is sometimes less than 9 cm. For example, when sowing garlic seedlings, the spacing usually requires a spacing of 5 to 6 cm. Obviously, the existing garlic seeder cannot meet the above-mentioned spacing requirements. In order to solve the above-mentioned technical problems, the existing technology generally adopts the method of sowing twice for staggered sowing, but this will undoubtedly seriously affect the sowing efficiency, and the accuracy of the spacing is difficult to control during actual operation, and deviations are easy to occur. Therefore, it is very necessary to design a new type of garlic sowing equipment, so that it can achieve accurate and efficient sowing with smaller spacing.

Assuming that the sowing plant spacing requirement is L cm, the sowing plant spacing of the upright planting mechanism A and the upright planting mechanism B is set to 2L cm, and the spacing between the upright planting mechanism A and the upright planting mechanism B is set to S cm, then the expression of S is as follows:

By adjusting the spacing between the two planting mechanisms, the planting position of the rear planting mechanism can be located between the two adjacent planting positions of the front planting mechanism, thereby achieving sowing with a smaller plant spacing. (2) By designing chain drive A and chain drive B, the pressing wheel is used as the power source and transmitted to the rear planting mechanism and the rear seed taking mechanism. In order to ensure the synchronization of the two sets of sowing mechanisms, the rear planting mechanism transmits power to the front planting mechanism through a synchronous multi-stage gear mechanism, and the rear seed taking mechanism transmits power to the front seed taking mechanism through a synchronous reverse transmission mechanism. Not only is the power transmission reliable, but also synchronization is ensured; (3) By arranging the two seed taking mechanisms relative to each other, a common seed box can be achieved, which is conducive to efficient feeding.

The left end of the seed taking main shaft in the seed taking mechanism B is provided with a driven sprocket B, and the driving sprocket B is connected to the driven sprocket B through a chain B.

7. The garlic sowing device with a smaller plant spacing according to claim 6, characterized in that: The synchronous multi-stage gear transmission mechanism includes a driving gear, a driven gear and multiple intermediate gears. The driving gear is arranged on the left end of the lowering main shaft of the upright lowering mechanism B, and the driven gear is arranged on the left end of the lowering main shaft of the upright lowering mechanism A. The driving gear is meshed and transmitted with the driven gear through multiple intermediate gears, and the intermediate gears are arranged on the frame through an intermediate rotating shaft and a seat bearing.

8. The garlic sowing device with a smaller plant spacing according to claim 7, characterized in that: The synchronous reverse transmission mechanism includes two bevel gears A respectively arranged at the right ends of the two seed taking spindles, each of the bevel gears A is connected to a corresponding bevel gear B, the two bevel gears B are connected by a transmission rod, and the bevel gears A and B are arranged on a bevel gear seat.

9. The garlic sowing device with a smaller plant spacing according to claim 8, characterized in that: The rotary tillage mechanism includes a rotary tillage main shaft, both ends of which are rotatably arranged on a frame via seat bearings, a plurality of cutter disc seats are arranged at intervals along the length direction of the rotary tillage main shaft, a plurality of rotary tillage knives are arranged at intervals along the circumferential direction of the cutter disc seats, and the rotary tillage main shaft is connected to the agricultural machinery via a transmission box and a gear box.

10. A method for sowing garlic with a smaller plant spacing, characterized in that: Including the garlic sowing device with a smaller plant spacing as claimed in claim 9, assuming that the sowing plant spacing requirement is L cm, the sowing plant spacing of the upright planting mechanism A and the upright planting mechanism B is set to 2L cm, and the spacing between the upright planting mechanism A and the upright planting mechanism B is set to S cm, then the expression of S is as follows: S=(2L)×N+L Wherein, N is a positive integer, and the value of N must ensure that the vertical lowering mechanism A and the vertical lowering mechanism B do not interfere with each other; During sowing, the garlic sowing device with a smaller plant spacing is installed on the agricultural machine through a frame. The agricultural machine drives the rotary tillage mechanism to rotary till the land. The rotation of the pressing wheel drives the pressing main shaft to rotate. The pressing main shaft drives the upright planting mechanism B to operate through the chain transmission A. The upright planting mechanism B drives the seed taking mechanism B to operate through the chain transmission B, and drives the upright planting mechanism A to operate through the synchronous multi-stage gear transmission mechanism. The seed taking mechanism B drives the seed taking mechanism A to operate through the synchronous reverse transmission mechanism. The seed taking spoons on the seed taking mechanism A and the seed taking mechanism B respectively take seeds and send the garlic seeds to the corresponding duckbill for receiving the material, and the upright planting mechanism B drives the seed taking mechanism A to operate. The duckbill on the mechanism A and the upright planting mechanism B opens the receiving duckbill during the rotation process, and the garlic seeds in the receiving duckbill fall into the duckbill. The duckbill remains upright by self-rotation during the rotation process, and opens under the action of the opening and closing drive disk and the collision roller when the duckbill rotates to the planting position, and the garlic seeds are planted into the soil for complete sowing. The garlic sowing can be completed uninterruptedly through continuous operation, and the spacing design of the upright planting mechanism A and the upright planting mechanism B ensures that the planting position of the upright planting mechanism B is located between two adjacent planting positions of the upright planting mechanism A, thereby ultimately achieving sowing with a smaller plant spacing.
