Problems solved by technology

The main problems are: 1. Poor adaptability, only suitable for sandy loam soil, because the seeding of the hole forming device is greatly affected by the soil condition, when the soil viscosity is high, the soil will be trapped and cause seed leakage, and the opening device will be stained with soil to cause failure Seeding depth, resulting in missed seeds, holes, and lack of seedlings; 2. The principle of the brush-type seeding mechanism is backward, and the accuracy and reliability of the secondary seeding are poor; 3. The seeding depth cannot be adjusted; 4. The opening device of the cavitation device is easy to tear the film ; 5. It is impossible to realize the simultaneous application of seeds and fertilizers

Embodiment Construction

[0017] 1. Wheel shaft 2, cam 3, wheel cover 4, wheel disc 5, ring belt 6, slider 7, spring 8, ejector rod 9, sleeve 10, pressure plate 11, annular cavity 12, groove 13, duck Nozzle 14, seed inlet 15, fertilizer inlet 16, seed cavity 17, fertilizer cavity 18, side plate 19, convex rib 20, connecting shaft 21, positioning block 22, fixing piece 23, pin hole 24, pin shaft

[0018] In the embodiment 1 shown in Figures 1-2: the wheel shaft 1 is fixed on the frame, the cam 2 is fixedly connected with the wheel shaft 1 with a key, the wheel disc 4 is set on the wheel shaft 1 and can rotate around the wheel shaft 1, and the wheel disc cover 3 is fixed On the cam 2 and covered on the wheel 4, the two can rotate relatively. There are three rings 5 ​​inside the wheel 4 to divide the space between the wheel cover 3 and the wheel 4 into two concentric annular cavities. 11. A plurality of cavitator assemblies are evenly arranged radially on the wheel 4 to form a steering wheel. Each cavita...

Abstract

A steering wheel type hill sower able to respectively apply fertilizer, form pits and seed in the pits is composed of a seed discharging wheel and multiple pit forming assemblages. Said seed discharging wheel consisting of axle, cam fixed to the axle, wheel disk and the cover of said wheel disk. Said multiple pit forming assemblages radically arranged on said wheel disk to form a steering wheel is composed of several pit forming units consisting of slide block, spring, ejecting rod, sleeve pipe with tangent lower end and pressing plate.

Description

Technical field [0001] The invention provides a rudder wheel-type hole seeder for distributing seeds and fertilizers and belongs to the technical field of agricultural machinery. Background technique [0002] The existing scientific research or product-type film-covered hole seeder is mainly composed of a duckbill hole opener, a roller, a seed box, a seed introduction tube, a seed discharge tray, a seed delivery tube, etc., wherein the seeds in the seed box enter through the seed delivery tube. In the inner cavity of the seeding disc, when the walking roller drives the seeding disc to rotate, the seeds, under the action of gravity and centrifugal inertial force, first enter the seed capsule area in the seed filling area, and then enter the small hole in the inner nest. During the rotation of the seed-discharging disc, the excess seeds in the seed-sac area slide down by their own weight in the seed-clearing area, and the quantitative seeds that enter the inner nest are sent t...
