Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology and relates to a deep application and return of rice straw to the field machine. Background Technology

[0002] Returning rice straw to the field can achieve the goals of fertilizing the field, improving soil quality, reducing the cost of field preparation, and shortening the idle period of rice fields. However, the straw produced by rice combine harvesters after harvesting rice is generally not crushed, resulting in poor straw return to the field. Rice stubble is also difficult to handle. In response to this problem, this application proposes a deep-applying straw return machine that can effectively handle the problem of returning rice straw to the field. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a deep rice straw application and return machine. The technical problem to be solved by this invention is how to crush rice straw and stubble and then bury them in the soil layer of the field.

[0004] The objective of this invention can be achieved through the following technical solution: A rice straw deep-applying and returning machine, characterized in that it includes a machine body, a walking unit, a picking unit, a crushing unit, and a straw-burying unit. The walking unit includes a steering wheel, a motor, an active track wheel, a passive track wheel, and a walking track. The walking track is traction-driven between the active track wheel and the passive track wheel, and the motor drives the active track wheel to rotate. The picking unit includes a guide cylinder and a guide belt. A plurality of picking plates are evenly spaced on the outer side of the guide belt. The guide belt is composed of two parts respectively arranged on the two sides of the guide cylinder. The traction roller at one end pulls the straw, and the rotation of the guide belt can transport the straw from the lower end of the guide cylinder to the upper end; the crushing unit includes a crushing box and a crushing mechanism located inside the crushing box. The bottom of the crushing box is provided with a conveying cylinder that can feed the crushed straw into the two straight sections between the walking track; the straw burying unit includes several feeding positioning holes opened on the walking track. The active track wheel is provided with a cutting tool adapted to the feeding positioning hole. The cutting tool can pass through the feeding positioning hole and insert into the soil layer; the picking unit can feed the straw into the crushing box.

[0005] Furthermore, the picking unit also includes an auxiliary picking wheel rotatably connected to the inlet of the guide cylinder. The auxiliary picking wheel is evenly provided with a plurality of auxiliary feeding plates on its outer circumference. The rotation direction of the auxiliary picking wheel is opposite to the rotation direction of the traction roller located at the inlet of the guide cylinder.

[0006] Furthermore, the crushing mechanism includes a scraper rotatably connected inside the crushing box. Each end of the scraper has a bevel gear. Two crushing wheels are also rotatably connected inside the crushing box. Each crushing wheel has a bevel gear that meshes with the first bevel gear. The axis of the crushing wheel is perpendicular to the axis of the scraper. Each crushing wheel has a spiral crushing blade. When the crushing wheel rotates, the spiral crushing blade can push the straw above the two crushing wheels toward one side of the scraper.

[0007] Furthermore, the pickup piece is comb-shaped.

[0008] Furthermore, the motor is connected to the scraper via belt one, the motor is connected to the drive track wheel via belt two, the driven track wheel is connected to the auxiliary pickup wheel via belt three, an intermediate wheel is rotatably connected at the inlet of the guide cylinder, the intermediate wheel is connected to the traction roller at the inlet of the guide cylinder via belt four, a gear one is provided on the intermediate wheel, and a gear two that meshes with the gear one is provided on the auxiliary pickup wheel.

[0009] This solution uses an electric power source. The picking unit is a straw lifting mechanism with a collection function. The auxiliary picking wheel and the guide belt with picking blades send the straw that falls on the field after rice harvesting into the crushing box. After being crushed, it is sent into the middle of the two straight sections of the walking track. The feeding positioning hole on the walking track is used for the traction of the walking track on the one hand, and on the other hand, it allows the straw powder to be inserted into the soil layer by the insert blade at the feeding positioning hole.

[0010] Rice stubble is scraped apart by a comb-shaped pick-up blade, and the straw on the stubble is scraped off, so that it is sent into the crushing box and finally inserted into the soil. Attached Figure Description

Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, the power transmission method is as follows: Motor 3 is located on the upper part of the machine body 1, and the battery is located on one side of Motor 3 to supply power to Motor 3. Motor 3 is connected to scraper 17 through belt 1 21 and to drive track wheel 4 through belt 2 22. Drive track wheel 4 transmits power to passive track wheel 5 through walking track 6. Passive track wheel 5 is connected to auxiliary pickup wheel 15 through belt 3 23. An intermediate wheel 24 is rotatably connected at the inlet of guide cylinder 7. Intermediate wheel 24 is connected to traction roller 10 at the inlet of guide cylinder 7 through belt 4 25. Gear 1 is provided on intermediate wheel 24, and gear 2 is provided on auxiliary pickup wheel 15 to mesh with gear 1. This ensures that traction roller 10 at the inlet of guide cylinder 7 and auxiliary pickup wheel 15 rotate in opposite directions. The position of auxiliary pickup wheel 15 is slightly higher than traction roller 10 at the inlet of guide cylinder 7. The function of auxiliary pickup wheel 15 is to prevent the straw collected by pickup plate 9 from falling off and to ensure that it can enter guide cylinder 7. In terms of linear speed, the linear speed of the guide belt 8 is greater than that of the walking track 6 due to the presence of the intermediate wheel 24. Combined with the smaller diameter of the traction roller 10, the traction roller 10 at the inlet of the guide cylinder 7 rotates at high speed.

[0018] like Figures 1-4 As shown, in the picking unit, the adjacent picking plates 9 at the traction roller 10 are in an open state. The inlet of the guide cylinder 7 facilitates the collection of straw, and the outlet of the guide cylinder 7 facilitates the release of straw into the crushing box 11. The picking plates 9 are curved, so that the straw can be "caught" in the straight section of the guide belt 8. The comb-shaped picking plates 9 can not only collect straw on the ground, but also "scrape" the rice stubble.

[0019] The crushing unit adopts a repeated crushing method. The bevel gears 18 on both sides of the scraper 17 respectively transmit power to the two crushing wheels 19 perpendicular to the scraper 17. The two crushing wheels 19 mesh inward to crush the straw. After crushing, the straw powder falls into the bottom of the crushing box 11 and is sent by the conveying cylinder 12 between the two straight sections of the walking track 6. Straw that cannot be crushed enough to pass between the two crushing wheels 19 is further cut by the scraper 17 and sent back above the two crushing wheels 19. In order to ensure that the crushing wheels 19 can guide the material, the front end of the crushing wheel 19 can be slightly higher than the rear end. In addition, the spiral crushing blade strips 20 used to cut the straw can also guide the straw backward. The scraper 17 has a multi-blade disc 26 structure with the blade discs 26 arranged alternately. The wall of the crushing box 11 is provided with passive blades 27 adapted to the blade discs 26. The cooperation of the rotating blade discs 26 and the passive blades 27 can have a secondary crushing effect on the straw.

[0020] The outlet of the conveying cylinder 12 is basically aligned with the moving trajectory of the feed positioning hole 13, so that the crushed straw can fall into the feed positioning hole 13 as much as possible. The distribution area of ​​the feed positioning hole 13 on the walking track 6 accounts for about 50%. Most of the straw powder can be effectively buried in the soil. The straw powder that does not fall into the feed positioning hole 13 has a chance to fall back into the feed positioning hole 13 after the walking track 6 rotates.

[0021] The presence of the walking track 6 allows the cutting blade 14 to be inserted deeper into the soil, giving the agricultural machine good passability. This is also why the cutting blade 14 can bury the straw deep in the soil without causing significant "damage" to the ground, because turning the ground over would cause the straw to re-emerge above the soil surface.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
