Description

Technical Field

[0001] The invention relates to the technical field of agricultural crop planting, in particular to a hilly dry land sesame rotary tillage, fertilization, spraying, film covering and hole seeding machine. Background Art

[0002] Sesame is a plant of the genus Sesame in the family Pedulaceae and is an oil crop. When planting, the steps include loosening the soil, spraying pesticides and fertilizing, laying mulch film, hole sowing and covering the soil. However, hilly areas are mostly mountainous and rugged. Modern machinery will cause shaking due to the uneven terrain when planting on a large scale. Since sesame seeds are small and the cotyledons have weak ability to top the soil, if there is no soil covering or the soil covering is too thick, it will seriously affect the emergence rate. Generally, 3cm±0.5cm of soil covering is appropriate. Even soil covering can provide a stable environment for seeds, maintain soil moisture, and is conducive to seed absorption of water and nutrients, promoting germination and rooting. At the same time, soil covering also plays a limiting role on the mulch film to prevent it from peeling off. The covering soil is the loose soil collected from the field from top to bottom to complete the covering of the soil layer on the laid mulch film and sesame seeds. Due to the uneven terrain, the shaking of the machinery during operation causes uneven soil spreading when covering the soil layer, which makes the soil layer falling on the mulch film unevenly distributed, and requires later supplementary manual covering operations. Summary of the invention

[0003] The purpose of the present invention is to propose a hilly dryland sesame rotary tillage, fertilization, spraying, mulching and hole seeder, which aims to improve the problem of uneven formation of soil layer on the covering film caused by uneven spreading of loose soil during covering operation due to uneven terrain in modern mechanical planting in hilly and mountainous areas.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1 -Attached Figure 6 , a hilly dry land sesame rotary tillage fertilization spraying film mulching combined hole seeding machine, comprising a soil covering mechanism, the soil covering mechanism includes:

[0038] The transfer chamber 1 is a circular cylindrical structure with an inlet at the top and an outlet at the bottom;

[0039] The rotating roller 2 is coaxially arranged in the transfer bin 1 to form a transfer space with the inner wall of the transfer bin 1;

[0040] A plurality of straight plates 3 are arranged equidistantly on the outer wall of the rotating roller 2 with the virtual central axis direction of the rotating roller 2 as the center circumference;

[0041] A plurality of arc plates 4 are fixedly arranged on the outer wall of the rotating roller 2 at equal intervals around the circumference, and the arc plates 4 are arranged between two adjacent straight plates 3, and the two ends of the arc plates 4 are fixedly connected to the two adjacent straight plates 3 respectively;

[0042] Among them, many small compartments that separate the transfer space are formed between the multiple straight plates 3 and the multiple curved plates 4. The straight plates 3 and the curved plates 4 are both arranged in close contact with the inner wall of the transfer bin 1. When a driving force is applied to the rotating roller 2 to make it rotate, many small compartments are formed to follow and rotate synchronously.

[0043] Through the above technical scheme, after the loose soil enters the transfer bin 1 through the inlet, it will be gradually collected in each small compartment by the rotating roller 2, and the soil collected in the small compartment will follow the rotating roller 2 to rotate to the outlet and fall onto the laid ground film. Since the straight plate 3 and the curved plate 4 are both arranged in close contact with the inner wall of the transfer bin 1, each small compartment is an independent small space. Through the combined restraint of the straight plate 3, the curved plate 4 and the inner wall of the transfer bin 1, and the power drive of the rotating roller 2, the loose soil inside the small compartment will not move randomly due to bumps and vibrations even when the machine is operating on uneven terrain, and the soil discharged through the outlet will finally fall evenly on the ground film.

[0044] The covering mechanism also includes:

[0045] A hopper 5, the lower part of which is connected to the inlet of the transfer bin 1;

[0046] The motor 6 is mounted on the transfer bin 1 , and its output shaft penetrates into the transfer bin 1 and is fixedly connected with the rotating roller 2 coaxially.

[0047] The above solves the problem that the loose soil moves randomly inside the machine and falls unevenly on the ground film due to the bumps caused by the machine when plowing on uneven terrain. However, at the moment when the soil leaves the outlet, due to the lack of corresponding restrictions, the bumps of the machine will also cause the final covering soil layer to be unevenly distributed. Therefore, the following improvements are made:

[0048] The straight plate 3 and the curved plate 4 are densely provided with bristles that can slide, and the formed brush bundles 7 can be controlled to slide in the straight plate 3 and the curved plate 4. The brush bundles 7 are extended at the outlet of the corresponding transfer bin 1 and extend toward the ground film. The falling path of the soil from the outlet to the ground film is blocked by the extended dense brush bundles 7, wherein the bristles and the brush bundles 7 are made of hard hair, such as bristles, horsetail hair, or artificial fiber nylon.

[0049] A circular groove 8 is provided inside the rotating roller 2, and a plurality of slide plates 9 equidistantly arranged in a circle are arranged inside the circular groove 8, and the number of the slide plates 9 is the same as that of the straight plate 3. One end of the brush bundle 7 is adhered to the slide plate 9, and the slide plate 9 is elastically arranged between the rotating roller 2. A plurality of arc blocks 10 equidistantly arranged in a circle are provided inside the circular groove 8, and the number of the arc blocks 10 is the same as that of the arc plate 4. One end of the brush bundle 7 is adhered to the arc block 10, and the arc block 10 is elastically arranged between the rotating roller 2. The straight plate 3, the arc plate 4 and the rotating roller 2 are all provided with a channel 11 for the brush bundle 7 to slide. A cam mechanism is arranged inside the circular groove 8, and the protruding portion 17 of the cam corresponds to the outlet of the transfer bin 1, and pushes the slide plate 9 and the arc block 10 rotated to the outlet position of the transfer bin 1 to extend the brush bundle 7.

[0050] A plurality of circumferentially equidistantly arranged fixed blocks 12 are fixedly arranged inside the rotating roller 2, the fixed blocks 12 are fixedly connected to fixed rods 13, the fixed blocks 12 are also slidably connected to clamping blocks 14, the fixed rods 13 penetrate the clamping blocks 14 and are slidably connected, each clamping block 14 is fixedly connected to the corresponding slide plate 9 and arc block 10, a compression spring 15 is sleeved on the outer wall of the fixed rod 13, the two ends of the compression spring 15 are respectively connected to the fixed block 12 and the clamping block 14, the elastic force of the compression spring 15 makes the clamping block 14 approach the virtual center axis direction of the rotating roller 2, wherein the arc blocks 10 of different layers are fixedly connected by connecting blocks 26, and the clamping block 14 is fixedly connected to the connecting block 26.

[0051] The cam mechanism comprises a fixing member 16 located inside the circular groove 8 . The fixing member 16 comprises a protruding portion 17 . The fixing member 16 is fixedly connected to the rotating roller 2 .

[0052] The combined seed drill also includes:

[0053] Driving a car 18;

[0054] The combined frame 19 is connected to the rear of the driving vehicle 18;

[0055] A rotary tiller 20 is connected to the combined frame 19;

[0056] A fertilizer spraying chamber 21 is connected to the combined frame 19;

[0057] The seed drill 22 is connected to the joint frame 19;

[0058] The laminating machine 23 is connected to the joint frame 19;

[0059] Among them, the hopper 5 is located at the rear and is connected to the combined frame 19.

[0060] The hopper 5 is fixedly connected with a folding plate 24 , and a hydraulic cylinder 25 is installed on the combined frame 19 . The output shaft of the hydraulic cylinder 25 is fixedly connected with the folding plate 24 , and the position of the hopper 5 in the vertical direction is regulated by the hydraulic cylinder 25 .

[0061] Working principle:

[0062] The driving vehicle 18 provides power to drive the combined frame 19 to move, and then the rotary tiller 20 turns the ground to loosen the soil, the fertilizer spraying bin 21 sprays the medicine and applies waste, the hole sower 22 sows the sesame seeds, and then the mulching machine 23 lays the ground film. This is a conventional technology that has been widely used;

[0063] Rotating the nut will cause the vertical rod connected to the nut thread to be adjusted upward or downward accordingly, so as to control the distance between the outlet of the transfer bin 1 and the ground film;

[0064] Prepare enough loose soil in advance and put it into the hopper 5, adjust the running speed of the motor 6, so as to match the advancement of the soil covering mechanism, and make the rotation angular velocity of the rotating roller 2 as close as possible to the linear velocity of the advancement of the soil covering mechanism;

[0065] After the soil in the hopper 5 enters the transfer bin 1 through the inlet, it will be gradually collected in each small compartment by the rotating roller 2. The soil collected in the small compartment follows the rotating roller 2 to the outlet and falls onto the laid ground film.

[0066] When the slide plate 9 and the arc block 10 rotating with the rotating roller 2 touch the protruding portion 17 of the fixing member 16, they will be resisted and thus overcome the elastic force of the compression spring 15 to push the brush bundle 7 outward, so that the brush bundle 7 extends out of the outlet.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
