Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and more specifically, to an organic fertilizer application device used in conjunction with a rotary tiller. Background Technology

[0002] In agricultural production, organic fertilizer plays a vital role in soil improvement and crop growth. It not only provides crops with comprehensive and long-lasting nutrition, but also increases and renews soil organic matter, promotes microbial reproduction, and improves the soil's physical, chemical, and biological properties, making it a major nutrient source for green food production. However, existing rotary tillers with fertilization functions lack effective structural optimization designs tailored to the characteristics of organic fertilizers.

[0003] Existing organic fertilizer application devices used with rotary tillers have some problems in practical applications. The synchronous feeding of fertilizer by the device along with the rotary tiller's operation makes it difficult to precisely control the amount of fertilizer applied due to the varying speeds of the tiller. This can easily lead to over- or under-fertilization. Over-fertilization results in fertilizer waste and environmental pollution, while under-fertilization fails to meet the crop's growth needs. Therefore, we propose an organic fertilizer application device designed for use with rotary tillers. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an organic fertilizer application device for use with rotary tillers. This device solves the technical problem that the different working speeds of rotary tillers make it difficult to accurately control the amount of fertilizer, resulting in over- or under-fertilization and affecting the fertilization effect.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an organic fertilizer application device for use with a rotary tiller, comprising a shock-absorbing seat installed on the top of the rotary tiller body, a fertilizer application device for loading organic fertilizer fixedly installed on the top of the shock-absorbing seat, a hopper passing through the top of the rotary tiller body fixedly provided at the bottom of the fertilizer application device, and a quantitative feeding component for controlling the amount of fertilizer discharged from the bottom outlet of the fertilizer application device fixedly installed on the top of the rotary tiller body. The quantitative feeding assembly includes connecting shafts rotatably mounted on both sides of the bottom facing surface of the fertilizer applicator, a fixed rod fixedly connected between the two connecting shafts, and several diverter plates arranged in an array on the outer wall of the fixed rod, the ends of the several diverter plates can fit against the inner wall of the fertilizer applicator during rotation, and a drive motor fixed to the top of the rotary tiller body is fixedly mounted on the end of one connecting shaft.

[0006] The design of the quantitative feeding component is particularly crucial in this invention. When the drive motor rotates the connecting shaft, fixing rod, and diverting plate, the space formed between adjacent diverting plates precisely receives the organic fertilizer, and the ends of the diverting plates fit snugly against the inner wall of the fertilizer applicator, effectively preventing leakage. By controlling the speed of the drive motor, the feeding amount can be flexibly adjusted to meet the needs of different soils and crops for organic fertilizer, achieving precise fertilization, which improves fertilizer utilization and avoids waste. Furthermore, the collection trough on the diverting plate better collects and transports organic fertilizer during rotation, and the rounded end design reduces friction with the inner wall of the fertilizer applicator, extending the device's service life.

[0007] Preferably, each of the diverter plates has an arc-shaped material collection groove on the same side, and the ends of each diverter plate are rounded edges.

[0008] Preferably, a screening plate is fixedly connected between the inner side of the connection between the hopper and the fertilizer application device, and the screening plate has several strip-shaped screening grooves on its wall.

[0009] Preferably, a plurality of striking components for striking the screening plate are fixedly connected between the opposing surfaces inside the hopper, and the bottom end of the striking components can press against the top of each diverter plate.

[0010] Preferably, the striking assembly includes a horizontal plate, an adjusting plate is provided through the center of the horizontal plate wall, and a number of striking plates flush with the top of the adjusting plate are fixedly provided on the top side of the horizontal plate. Both ends of the adjusting plate and the ends of the striking plates are rounded edges, and elastic members connected to the inner wall of the hopper are fixedly provided on both sides of the striking assembly.

[0011] Preferably, each of the elastic elements includes two connecting strips, and an elastic corrugated plate is fixedly connected between the two connecting strips. The corrugated plate has a plurality of elastic cavities constructed on its wall.

[0012] Preferably, the top of the horizontal plate is integrally formed with a guide plate, and the cross-sectional shape of the guide plate is an equilateral triangle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The design of the quantitative feeding component is particularly crucial in this invention. When the drive motor rotates the connecting shaft, fixing rod, and diverting plate, the space formed between adjacent diverting plates can precisely receive organic fertilizer, and the ends of the diverting plates fit snugly against the inner wall of the fertilizer applicator, effectively preventing leakage. By controlling the speed of the drive motor, the feeding amount can be flexibly adjusted to meet the needs of different soils and crops for organic fertilizer, achieving precise fertilization, which improves fertilizer utilization and avoids waste. Furthermore, the collection trough on the diverting plate can better collect and transport organic fertilizer during rotation, and the rounded end design reduces friction with the inner wall of the fertilizer applicator, extending the service life of the device.

[0014] 2. This utility model also filters organic fertilizer through the strip-shaped screening troughs on the screening plate, intercepting lumps or large pieces of fertilizer to ensure that the fertilizer particles entering the feeding stage are of uniform size, which is beneficial for subsequent mixing with the soil. The design of the striking component is ingenious. When the diverting plate rotates, its top presses against the adjusting plate. Under the action of the elastic element, the striking plate continuously strikes the screening plate, preventing fertilizer from accumulating and clogging on the screening trough, and ensuring smooth screening and feeding. The corrugated plate and elastic cavity in the elastic element provide good elastic recovery force, making the striking action continuous and effective. Attached Figure Description

[0017] like Figures 1 to 5As shown, this utility model relates to an organic fertilizer application device used in conjunction with a rotary tiller. It includes a shock-absorbing seat 2 installed on the top of the rotary tiller body 1. A fertilizer application device 3 for loading organic fertilizer is fixedly installed on the top of the shock-absorbing seat 2. A hopper 4 passing through the top of the rotary tiller body 1 is fixedly installed at the bottom of the fertilizer application device 3. A quantitative feeding component 5 for controlling the amount of fertilizer discharged from the bottom outlet of the fertilizer application device 3 is fixedly installed on the top of the rotary tiller body 1. The rotary tiller body 1, shock-absorbing seat 2, and fertilizer application device 3 are all existing technology structures. The fertilizer application device 3 has an internal crushing mechanism that can crush the organic fertilizer inside, preventing it from clumping and affecting the feeding, thus maintaining smooth feeding. The connection between the hopper 4 and the rotary tiller body 1 allows for fertilization during the rotary tilling process, thereby improving the fertilization effect. The quantitative feeding component 5 controls the amount of fertilizer applied.

[0018] The quantitative feeding component 5 includes connecting shafts 501 rotatably mounted on both sides of the bottom facing surface of the fertilizer applicator 3. A fixing rod 502 is fixedly connected between the two connecting shafts 501. Several diverting plates 503 are arranged in an array on the outer wall of the fixing rod 502. The ends of the diverting plates 503 can be in contact with the inner wall of the fertilizer applicator 3 during rotation. A drive motor 505 fixed to the top of the rotary tiller body 1 is fixedly mounted on the end of one connecting shaft 501. By controlling the rotation of the fixing rod 502 through the drive motor 505, the diverting plates 503 can divide the fertilizer. When the diverting plates 503 are in contact with the fertilizer applicator 3, the fertilizer can be prevented from falling. When the top diverting plate 503 rotates to the bottom position, the fertilization work can be completed. In this way, the amount of fertilizer can be controlled by the rotation speed, maintaining a fertilization speed that is compatible with the operation of the rotary tiller body 1 and improving the uniformity of the fertilization work.

[0019] In the embodiments of this utility model, each diversion plate 503 has an arc-shaped collection trough 504 on the same side, and the end of each diversion plate 503 is a rounded edge; the design of the collection trough 504 can increase the amount of fertilizer collected, improve the fullness of fertilizer distribution, and further improve the fertilization effect.

[0020] In an embodiment of this utility model, a screening plate 401 is fixedly connected between the inner side of the connection between the hopper 4 and the fertilizer application device 3. Several strip-shaped screening grooves 402 are constructed on the wall of the screening plate 401. The design of the screening grooves 402 on the screening plate 401 can improve the uniformity of fertilizer feeding and screen out lumpy fertilizer.

[0021] In this embodiment of the present invention, a plurality of striking components 6 for striking the screening plate 401 are fixedly connected between the opposing surfaces inside the hopper 4, and the bottom end of the striking component 6 can press against the top end of each diverter plate 503; the design of the striking component 6 allows the striking component 6 to be offset during the operation of the quantitative feeding component 5 to strike the screening plate 401, and the vibration effect can prevent fertilizer from clogging the screening trough 402 and maintain the smoothness of feeding.

[0022] In an embodiment of this utility model, the striking component 6 includes a horizontal plate 601, an adjusting plate 602 is provided through the center of the plate wall of the horizontal plate 601, and several striking plates 603 flush with the top of the adjusting plate 602 are fixedly provided on the top side of the horizontal plate 601. Both ends of the adjusting plate 602 and the ends of the striking plates 603 are rounded edges. Elastic members 7 connected to the inner wall of the hopper 4 are fixedly provided on both sides of the striking component 6. The adjusting plate 602 can cooperate with the diversion plate 503. When the diversion plate 503 rotates and contacts the bottom of the adjusting plate 602, a squeezing force can be formed, so that the horizontal plate 601 can move upward under the deformation effect of the elastic member 7. When separated, the horizontal plate 601 can be reset. In this way, the effect of repeatedly striking the screening plate 401 can be achieved during repeated offset.

[0023] In the embodiments of this utility model, each elastic element 7 includes two connecting strips 701, and a corrugated plate 702 with elasticity is fixedly connected between the two connecting strips 701. The wall of the corrugated plate 702 is constructed with a plurality of elastic cavities 703. The connecting strips 701 on both sides can restrict the position of the corrugated plate 702. With the cooperation of the elastic cavities 703, the elastic bending effect of the corrugated plate 702 can be improved. Moreover, the wave shape can improve the compressive strength, make it less prone to deformation, and maintain the stability of the structure.

[0024] In the embodiments of this utility model, the top of the horizontal plate 601 is integrally formed with a guide plate 604, and the cross-sectional shape of the guide plate 604 is an equilateral triangle; the inclined design can have a certain material guiding effect and is not easy to accumulate when the fertilizer falls.

[0025] Working Principle: This embodiment provides an organic fertilizer application device for use with a rotary tiller. First, organic fertilizer is loaded into the application device 3. Vibrations generated during the operation of the rotary tiller body 1 are buffered by the top shock-absorbing seat 2, reducing the impact on the application device 3. When fertilization is needed, the drive motor 505 in the quantitative feeding assembly 5 is activated. The drive motor 505 drives the connecting shaft 501 on one side to rotate, which in turn causes the fixed rod 502 between the two connecting shafts 501 to rotate. Several diverter plates 503 on the outer wall of the fixed rod 502 rotate accordingly. Since the ends of the diverter plates 503 can fit against the inner wall of the application device 3 during rotation, the space formed between adjacent diverter plates 503 carries the organic fertilizer downwards. Furthermore, the arc-shaped collection trough 504 on the diversion plate 503 can better collect and carry organic fertilizer. The rounded end design reduces friction with the inner wall of the fertilizer applicator 3 while ensuring a tight fit. By controlling the speed of the drive motor 505, the rotation speed of the diversion plate 503 can be adjusted, thereby controlling the amount of material discharged per unit time and achieving quantitative discharge. Before the organic fertilizer falls from the bottom of the fertilizer applicator 3, it will first pass through the screening plate 401. The strip screening trough 402 on the screening plate 401 can screen the organic fertilizer, blocking large impurities or uncomposted organic fertilizer, allowing the qualified organic fertilizer to enter the discharge hopper 4 through the screening trough 402. During the rotation of the diversion plate 503, its top end will press against the bottom end of the striking component 6. When the diversion plate 503 rotates to contact the adjusting plate 602, it will push the adjusting plate 602 upward, and at the same time drive the striking plate 603 on the horizontal plate 601 upward, at which time the elastic element 7 is stretched. After the diverter plate 503 rotates past the adjusting plate 602, under the elastic action of the elastic element 7, the adjusting plate 602 and the striking plate 603 quickly return to their original position. The striking plate 603 strikes the screening plate 401, causing the screening plate 401 to vibrate and preventing organic fertilizer from clogging the screening trough 402. The corrugated plate 702 and the elastic cavity 703 in the elastic element 7 ensure good elastic recovery capability, while the rounded edge design of the adjusting plate 602 and the striking plate 603 reduces friction and wear when in contact with the diverter plate 503. In addition, the equilateral triangular cross-section shape of the guide plate 604 can guide the organic fertilizer passing through the screening plate 401, allowing the organic fertilizer to enter the hopper 4 more smoothly, and finally fall into the soil after being tilled by the rotary tiller through the hopper 4, completing the fertilization operation.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
