Description

Technical Field

[0001] The invention relates to the technical field of farmland straw, in particular to a farmland straw gathering and covering machine. Background Art

[0002] The straw gatherer and coverer is a key agricultural machinery used in modern agriculture, particularly in the implementation of conservation tillage and straw return. Its core function is to efficiently and automatically handle crop straw scattered in the field after harvest, creating conditions for subsequent no-till seeding. Simultaneously, covering the straw with soil accelerates its decomposition in the soil, promoting its conversion into organic matter and nutrients. It also effectively prevents straw loss due to wind and other factors in autumn and winter, thus achieving a recyclable straw resource.

[0003] The farmland straw gathering and covering machine in the prior art mainly includes a body, a bracket, a servo motor, a conveyor belt and a bucket. When in use, the bucket is usually used to scoop up the topsoil, and then transport it to the top of the straw through the transmission belt to achieve covering. However, in actual use, the straw is piled up together after being gathered, which is not conducive to the contact between the straw and the microorganisms in the soil, thereby leading to problems such as low straw decomposition efficiency. In addition, the straw is usually scattered above the topsoil. When the bucket scoops up the topsoil, the straw will be scooped up together, and then transported and covered with soil, so that the straw cannot be well gathered under the soil, which makes the straw easily blown away by the wind. On the one hand, it wastes resources, and on the other hand, it decomposes slowly, affecting the sowing and emergence of seedlings next year.

[0004] Therefore, in response to the above problems, a farmland straw gathering and covering machine is proposed. Summary of the Invention

When the bucket scoops up the topsoil, the straw will be scooped up together, and then transported and covered with soil, so that the straw cannot be well gathered under the soil, which makes the straw easily blown away by the wind. On the one hand, it wastes resources, and on the other hand, it decomposes slowly, affecting the sowing and emergence of seedlings in the next year. A farmland straw gathering and covering machine is proposed.

[0012] Preferably, a second scraper is fixedly connected to the bottom end of the bottom plate, and the bottom end of the second scraper abuts against the outer wall of the top of the pressure roller.

[0013] Preferably, the auxiliary structure includes a conveyor belt 2 installed on the top of the bucket, one end of the top rotating shaft of the conveyor belt 2 is fixedly connected to the transmission component 1, the outer wall of the middle part of the conveyor belt 2 is parallel to the top of the middle part of the bucket, and the outer wall of the conveyor belt 2 is fixedly connected to a plurality of lifting plates.

[0016] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art: The present invention provides a farmland straw gathering and covering machine, which uses a bulking structure to break up soil clods and the like using a material-splitting rod, and mixes and disperses a large amount of soil clods scooped up by a bucket with straw, thereby preventing large-particle soil clods from affecting subsequent soil and straw screening effects and soil covering quality. At the same time, the straw is evenly dispersed, which can increase the contact area between the straw and soil microorganisms, thereby improving the decomposition efficiency and decomposition effect.

[0017] The present invention provides a machine for gathering and covering straw for farmland. Through the effect of a screening structure, an arc-shaped wind knife is used to blow air to the soil and straw, so that the lighter straw is blown to the front of the traveling direction of the machine, while the soil falls relatively behind due to the greater gravity, thereby ensuring that the soil is stably and evenly covered on top of the straw, thereby realizing the covering operation and avoiding the problem of poor covering effect caused by the mixing of soil and straw. At the same time, the arc-shaped structure of the arc-shaped wind knife makes the blown air flow relatively concentrated toward the middle of the machine for gathering and covering straw for farmland, thereby ensuring that the straw falls stably in the groove shoveled by the bucket, avoiding the problem of the straw being blown away.

[0018] The present invention provides a machine for gathering and covering farmland straw. Through the function of the auxiliary structure, the lifting plate of the second conveyor belt can transport the soil and straw accumulated at the bottom of the bucket along the bucket to the top of the first conveyor belt, so as to avoid the soil and straw being accumulated at the bottom of the bucket due to gravity and friction, thereby affecting the normal feeding of the soil and straw. The inclined plate can gather the soil scattered on both sides of the bucket under pressure during the bucket shoveling process, so as to avoid subsequent soil contamination of the auger brush, thereby reducing its service life in a single use process, and avoiding the need for frequent shutdowns to maintain the auger brush when using the machine for gathering and covering farmland straw.

[0019] The present invention provides a farmland straw gathering and covering machine. Through the function of the gathering structure and the rotation of two auger brushes, the straw on both sides of the farmland straw gathering and covering machine can be gathered into the groove opened by the bucket, thereby improving the straw gathering effect and the straw utilization rate. At the same time, a certain space can be directly reserved on both sides of the straw pile, which is convenient for the subsequent planting of crops on both sides of the straw pile.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Specific examples are given below.

[0024] See also Figure 1 - Figure 11 The present invention provides a technical solution: a farmland straw gathering and covering machine, comprising a body 1, a bracket 2 is fixedly installed at the bottom of the body 1, a servo motor 3 is installed on the top of the bracket 2, a conveyor belt 4 is installed inside the body 1, a rotating shaft of the conveyor belt 4 is fixedly connected to the output end of the servo motor 3, a bucket 5 is fixedly connected to one side of the body 1, a bulking structure 6 is installed on the top of the body 1, a screening structure 7 is fixedly installed on the side of the bracket 2 away from the bucket 5, an auxiliary structure 8 is fixedly installed on the top of the bucket 5, and a gathering structure 9 is installed on both sides of the bracket 2, the bulking structure 6 includes a top frame 61 fixedly connected to the top of the inner wall of the body 1, and two reciprocating screw rods 64 are rotatably connected to the inside of the top frame 61, and one end of the two reciprocating screw rods 64 is connected to the top of the body 1. The transmission component 2 63 is installed at the same time, and the outer parts of the two reciprocating screw rods 64 are threadedly connected to the sliding rod 65, and the bottom ends of the two sliding rods 65 are rotatably connected to the rotating plates, and the two ends of the bottom ends of the two rotating plates are fixedly connected to the material-moving rod 69. The transmission component 1 62 and the transmission component 2 63 cooperate to drive the two reciprocating screw rods 64 to rotate, thereby causing the two sliding rods 65 to slide synchronously. During the sliding of the sliding rod 65, the material-moving rod 69 is driven to slide, and then the material-moving rod 69 can be driven to break up the soil blocks, etc., and mix and disperse the large amount of soil blocks shoveled up by the bucket 5 with the straw, so as to avoid large particles of soil blocks affecting the subsequent soil and straw screening effect and the covering quality. At the same time, the straw is evenly dispersed, which can increase the contact area between the straw and soil microorganisms, thereby improving the decomposition efficiency and decomposition effect.

[0025] like Figure 7 As shown, the outer wall of the top of the rotating plate is fixedly connected to a transmission gear 66, and the bottom end of the top frame 61 is fixedly connected to two sets of limit frames 68. The transmission gear 66 is located inside the limit frame 68, and the inside of the limit frame 68 is fixedly connected to a rack 67. The outer wall of the rack 67 is meshed with the outer wall of the transmission gear 66. When the slide rod 65 slides, the transmission gear 66 slides inside the limit frame 68. Under the meshing effect of the transmission gear 66 and the rack 67, the transmission gear 66 rotates, thereby driving the two material-moving rods 69 to rotate, thereby further improving the bulking effect.

[0026] like Figure 7As shown, the outer wall of the material-moving rod 69 is fixedly connected with a plurality of disordered inclined blades 610. The disordered blades 610 can break up and refine the soil clods during the rotation process, thereby making the soil more suitable for covering operations and improving the subsequent decomposition effect of straw.

[0027] like Figure 8 As shown, the screening structure 7 includes a fixed plate 71 fixedly connected to the side of the body 1 away from the bucket 5, and a plurality of elastic telescopic rods 73 are installed inside the fixed plate 71. The output end of the elastic telescopic rod 73 is fixedly connected to a scraper 72. The top of the scraper 72 abuts against the outer wall of the conveyor belt 1. The scraper 72 presses against the surface of the conveyor belt 4, which can clean the surface of the conveyor belt 1, thereby preventing soil and straw from sticking to the surface of the conveyor belt 4, which in turn causes the conveyor belt 4 to become stagnant and the operating load to increase. At the same time, under the action of the elastic telescopic rod 73, the scraper 72 always abuts against the surface of the conveyor belt 4, thereby ensuring the cleaning effect and avoiding the conveyor belt 4 from shaking when transporting soil, which in turn causes the scraper 72 to separate from the conveyor belt 4.

[0028] like Figure 9 As shown, the side of the bracket 2 away from the bucket 5 is fixedly connected to a connecting piece 74, and the side of the connecting piece 74 away from the bracket 2 is fixedly connected to an arc-shaped wind knife 77. The outer wall of the arc-shaped wind knife 77 is fixedly connected to a base 75, and the top of the base 75 is fixedly connected to a blower 76. The output end of the blower 76 is fixedly installed with the outer wall of the arc-shaped wind knife 77. When the soil and straw slide on the surface of the fixed plate 71, the blower 76 is started, thereby causing the arc-shaped wind knife 77 to blow air to the soil and straw. At this time, the mass is relatively light. The straw is blown down to the front of the traveling direction of the farmland straw gathering and covering machine, while the soil falls relatively behind it due to the greater gravity, thereby ensuring that the soil is stably and evenly covered on top of the straw, thereby realizing the covering operation, avoiding the problem of poor covering effect caused by the mixing of soil and straw. At the same time, the arc-shaped structure of the arc-shaped wind knife 77 makes the blown air flow relatively concentrated toward the middle of the farmland straw gathering and covering machine, thereby ensuring that the straw falls stably in the groove shoveled by the bucket 5, avoiding the problem of straw being blown away.

[0029] like Figure 9 and Figure 10As shown, a compacting assembly 78 is fixedly installed at the bottom end of the base 75, and the compacting assembly 78 includes a bottom plate 781, and a pressure roller 782 is rotatably connected to the bottom of the bottom plate 781. A plurality of elastic dampers 784 are fixedly installed at the bottom end of the base 75, and the output end of the elastic damper 784 is fixedly connected to the top end of the bottom plate 781. The pressure roller 782 is tightly pressed on the soil surface, thereby compacting the soil to prevent the surface soil from being lost due to factors such as wind, thereby causing the straw to be exposed. At the same time, the elastic damper 784 can make the pressure roller 782 always squeeze on the soil surface when the farmland straw gathering and covering machine is bumpy, thereby improving the soil compaction effect.

[0030] like Figure 10 As shown, the bottom end of the base plate 781 is fixedly connected to a scraper 2 783, and the bottom end of the scraper 2 783 abuts against the outer wall of the top of the pressure roller 782. The scraper 2 783 can clean the surface of the pressure roller 782 in real time, thereby preventing the surface of the pressure roller 782 from being contaminated with mud, thereby affecting its normal operation.

[0031] like Figure 3 As shown, the auxiliary structure 8 includes a conveyor belt 2 81 installed on the top of the bucket 5, one end of the top rotating shaft in the conveyor belt 2 81 is fixedly connected to the transmission component 1 62, the outer wall of the middle part of the conveyor belt 2 81 is parallel to the top of the middle part of the bucket 5, and the outer wall of the conveyor belt 2 81 is fixedly connected with a plurality of lifting plates 82. The lifting plates 82 of the conveyor belt 2 81 transport the soil and straw accumulated at the bottom of the bucket 5 along the bucket 5 to the top of the conveyor belt 1 4, so as to prevent the soil and straw from being accumulated at the bottom of the bucket 5 due to gravity and friction, thereby affecting the normal feeding of soil and straw.

[0032] like Figure 3 As shown, two inclined plates 83 are symmetrically fixedly connected to the bottom end of the bucket 5. The inclined plates 83 can gather the soil that is compressed and scattered on both sides of the bucket 5 during the shoveling process of the bucket 5, thereby avoiding subsequent soil contamination of the auger brush 94, thereby reducing its service life in a single use process, and avoiding the need for frequent shutdowns to maintain the auger brush 94 when using the farmland straw gathering and covering machine.

[0033] like Figure 11 As shown, the gathering structure 9 includes a servo motor 2 91 fixedly mounted on the top of the bracket 2, a transmission component 3 92 fixedly mounted on the output end of the servo motor 2 91, a transmission component 4 93 mounted on the bottom of the transmission component 3 92, and both ends of the transmission component 4 93 are rotatably connected to auger brushes 94. Both ends of the two auger brushes 94 are rotatably connected to the middle of the bracket 2. The servo motor 2 91 drives the transmission component 3 92 and the transmission component 4 93 to work, thereby causing the two auger brushes 94 to rotate synchronously and oppositely, thereby gathering the straw on both sides of the farmland straw coverer into the groove opened by the bucket 5, thereby improving the straw gathering effect and facilitating the subsequent planting of crops on both sides of the straw pile.

[0034] The working principle of the present invention is as follows: when in use, the farmland straw gathering and covering machine is installed on the rear end of the agricultural vehicle. At this time, the bucket 5 is inserted into the surface soil, the agricultural vehicle is started to drive the farmland straw gathering and covering machine to start moving, and at the same time, the servo motor 1 3 and the servo motor 2 91 are started. At this time, the bucket 5 scoops up the surface soil and straw, and the servo motor 1 3 drives the conveyor belt 1 4 to run while driving the transmission component 1 62 to work, thereby driving the conveyor belt 2 81 to run, and the lifting plate 82 of the conveyor belt 2 81 lifts the soil and straw accumulated at the bottom of the bucket 5. The straw is transported along the bucket 5 to the top of the conveyor belt 4, so as to prevent the soil and straw from being accumulated at the bottom of the bucket 5 due to gravity and friction, thereby affecting the normal feeding of the soil and straw. In the process of the farmland straw gathering and covering machine moving, the inclined plate 83 can gather the soil that is pressed and scattered on both sides of the bucket 5 during the process of shoveling the soil by the bucket 5, so as to prevent the subsequent soil from contaminating the auger brush 94, thereby reducing its service life in a single use process, and avoiding the need for frequent shutdowns to maintain the auger brush 94 when using the farmland straw gathering and covering machine; After the soil mixed with straw is transported to the top of the conveyor belt, the transmission component 1 62 and the transmission component 2 63 cooperate to drive the two reciprocating screw rods 64 to rotate, thereby causing the two sliding rods 65 to slide synchronously. During the sliding of the sliding rod 65, the material-dispensing rod 69 is driven to slide, which can drive the material-dispensing rod 69 to break up the soil clods, etc., and mix and disperse the large amount of soil clods scooped up by the bucket 5 with the straw, so as to prevent large particles of soil from affecting the subsequent soil and straw screening effect and soil covering quality. At the same time, the straw is evenly dispersed, which can increase the contact area between the straw and soil microorganisms, thereby improving the decomposition efficiency and decomposition effect. While the sliding rod 65 slides, the transmission gear 66 slides inside the limit frame 68. Under the meshing effect of the transmission gear 66 and the rack 67, the transmission gear 66 rotates, thereby driving the two material-dispensing rods 69 to rotate, thereby further improving the bulking effect. At the same time, the disordered blade 610 can crush and refine the soil clods during the rotation process, thereby making the soil more suitable for soil covering operations and improving the subsequent straw decomposition effect. The soil mixed with straw after dispersion passes through one end of the conveyor belt 2 81 and falls on the scraper 1 72 and the fixed plate 71 2, and then falls evenly, ensuring the dispersion effect of the soil and straw. At the same time, the scraper 1 72 presses against the surface of the conveyor belt 4, which can clean the surface of the conveyor belt 1, thereby preventing the soil and straw from sticking to the surface of the conveyor belt 4, which in turn causes the conveyor belt 4 to stagnate and the operating load to increase. At the same time, under the action of the elastic telescopic rod 73, the scraper 1 72 always presses against the surface of the conveyor belt 4, thereby ensuring the cleaning effect and preventing the conveyor belt 4 from shaking when transporting soil materials, thereby causing the scraper 1 72 to be detached from the conveyor belt 4. To solve the problem of separation, the soil and straw slide on the surface of the fixed plate 71, and the blower 76 is started, thereby causing the arc-shaped wind knife 77 to blow air to the soil and straw. At this time, the lighter straw is blown to the front of the traveling direction of the farmland straw gathering and covering machine, while the soil falls relatively behind due to the greater gravity, thereby ensuring that the soil is stably and evenly covered on top of the straw, thereby realizing the covering operation. At the same time, the arc-shaped structure of the arc-shaped wind knife 77 makes the blown air flow relatively concentrated toward the middle of the farmland straw gathering and covering machine, thereby ensuring that the straw falls stably in the groove shoveled by the bucket 5, avoiding the problem of the straw being blown away; After the soil covering is completed, the pressing roller 782 is pressed tightly against the soil surface to compact the soil, thereby preventing the topsoil from being lost due to factors such as wind, which in turn causes the straw to be exposed. At the same time, the elastic damper 784 can ensure that the pressing roller 782 is always pressed against the soil surface when the straw collecting and covering machine is bumpy, thereby improving the soil compaction effect. The scraper 2 783 can clean the surface of the pressing roller 782 in real time, thereby preventing the surface of the pressing roller 782 from being contaminated with mud, thereby affecting its normal operation. While the farmland straw gathering and covering machine is running, servo motor 2 91 drives transmission component 3 92 and transmission component 4 93 to work, thereby causing the two auger brushes 94 to rotate synchronously and in opposite directions, thereby gathering the straw on both sides of the farmland straw gathering and covering machine into the groove opened by the bucket 5, thereby improving the straw gathering effect and facilitating the subsequent planting of crops on both sides of the straw pile.
