Rice soil rock powder spreading device

Abstract

This application discloses a soil rock powder spreading device for paddy fields, belonging to the field of rock powder spreading technology. It includes a spreading frame with a hopper fixed on it, and a centrifugal application device fixed below the hopper. The centrifugal application device includes a rotatable and swingable material disc with multiple material plates arranged in a ring on its upper surface, forming a feeding zone between the plates. It also includes a guiding component for guiding the rock powder in the hopper. This application utilizes a rotating and swinging material disc. When the disc swings to a high position, the throwing angle is more horizontal, resulting in a farther material spread; at a low position, the angle is steeper, covering a closer area. This dynamic adjustment significantly expands the spreading radius, making it suitable for field operations or scenarios requiring wide-area spreading. By dynamically adjusting the spreading height through the up-and-down swing of the disc, the material's trajectory is diversified. The variations in throwing angle and centrifugal force at different heights disperse the material's landing point, reducing local accumulation or gaps.

Description

Technical Field

[0001] This application relates to the field of rock powder spreading technology, and more specifically, to a rock powder spreading device for rice soil. Background Technology

[0002] During rice cultivation, limestone and wollastonite powder were applied to improve the rice soil, and the effects of these applications on rice yield, quality, and carbon sequestration were observed.

[0003] Currently, traditional centrifugal spreading methods can only spread in one direction, which easily leads to "missed areas" or "accumulation areas," a small spreading radius, and a single trajectory for material landing.

[0004] In view of this, we propose a soil rock powder spreading device for rice paddies. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this application is to provide a rice soil rock powder spreading device, which solves the technical problems in the background art mentioned above, and realizes the technical effect of diversifying the landing trajectory of rock powder by dynamically adjusting the throwing height, and dispersing the landing point of the material by changing the throwing angle and centrifugal force at different heights, thereby reducing local accumulation or gaps.

[0007] Technical solution

[0008] This application provides a rice soil rock powder spreading device, including a spreading frame, a hopper fixed on the spreading frame, and a centrifugal application device fixed on the spreading frame and placed below the hopper. The centrifugal application device includes a rotatable and swingable material tray, and multiple material plates are distributed in a ring on the upper surface of the material tray, with a feeding area formed between the multiple material plates.

[0009] It also includes a material guiding component for guiding rock powder in the hopper, the outlet end of which is close to the discharge area.

[0010] As an optional solution to the technical solution of this application, the spreading frame is fixed with a first support and a second support, and a motor is rotatably connected to the second support, with the output shaft of the motor fixed coaxially with the material tray.

[0011] A servo electric cylinder is rotatably connected between the motor and the first bracket.

[0012] As an optional solution to the technical solution of this application, the material guiding component includes a telescopic cylinder, one end of which is fixed to the bottom of the hopper, and the other end is close to the material discharge area.

[0013] As an optional solution to the technical solution of this application, the lower end of the telescopic cylinder is fixedly connected to a guide cover, the guide cover is fixed to the motor by multiple sets of support frames, a material dispensing port is opened on one side of the guide cover, the guide cover is placed in the material feeding area and its lower edge abuts against the material tray.

[0014] As an optional solution to the technical solution of this application, a tamping rod is fixed on the upper surface of the material tray, and the upper end of the tamping rod is inserted into the hopper through the discharge port.

[0015] As an optional solution to the technical solution in this application, the tamping rod has a frustum-shaped structure that is narrow at the top and wide at the bottom.

[0016] As an optional solution to the technical solution in this application, a storage battery is fixed at the bottom of the spreading frame.

[0017] Beneficial effects

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] 1. This application utilizes a rotating and oscillating material tray. When the tray oscillates to a high position, the throwing angle becomes more horizontal, allowing the material to be thrown further. When the tray is at a low position, the angle is steeper, covering a closer area. This dynamic adjustment significantly expands the throwing radius, making it suitable for field operations or scenarios requiring wide-area sowing. By dynamically adjusting the throwing height through the up-and-down oscillation of the material tray, the trajectory of the material's landing point becomes diversified. The changes in the throwing angle and centrifugal force at different heights can disperse the material's landing point, reducing local accumulation or gaps.

[0020] 2. This application uses a swinging tamping bar to stir the rock powder in the hopper. When the tamping bar swings with the material tray, it periodically stirs the rock powder at the bottom of the hopper, breaks up the clumps, and forces the rock powder near the discharge port to flow loosely, effectively solving the problems of blockage and clumping in the throwing of rock powder.

[0021] 3. This application uses a material guiding component to guide the rock powder in the hopper to the feeding area to ensure accurate feeding of the rock powder. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-7 As shown, a rice soil rock powder spreading device includes a spreading frame 10. The fixing lugs on the back of the spreading frame 10 are fixedly mounted on the frame of a tractor by bolt and nut assembly. A hopper 20 fixed on the spreading frame 10 is used for storing rock powder. A centrifugal application device 30 is fixed on the spreading frame 10 and placed below the hopper 20. The centrifugal application device 30 includes a rotatable and swingable material tray 31. The material tray 31 is placed below the hopper 20. Multiple material plates 32 are distributed in a ring on the upper surface of the material tray 31. A feeding area 33 is formed between the multiple material plates 32 and is placed directly below the hopper 20.

[0032] It also includes a material guiding component 40 for guiding rock powder in hopper 20. The outlet end of the material guiding component 40 is close to the discharge area 33 so as to guide the rock powder in hopper 20 to the discharge area 33 through the material guiding component 40 to ensure accurate feeding of rock powder.

[0033] After the rock powder is guided to the feeding area 33 by the material guide component 40, the rotating material tray 31 drives the material plate 32 to rotate. Under the centrifugal force, the rock powder is applied to the soil. At the same time, as the material tray 31 rotates, it also swings back and forth. When the material tray 31 swings to a high position, the throwing angle is more horizontal and the material is thrown farther. When it is at a low position, the angle is steeper and it covers a closer area. This dynamic adjustment significantly expands the throwing radius and is suitable for field operations or scenarios that require wide-area sowing. By dynamically adjusting the throwing height by swinging the material tray 31 up and down, the trajectory of the material landing point is diversified. The different throwing angles and centrifugal forces at different heights can disperse the landing point of the material and reduce local accumulation or gaps.

[0034] like Figure 2 , Figure 4 , Figure 6 As shown, a first support 11 and a second support 12 are fixed on the spreading frame 10. A second shaft 351 is symmetrically fixed on the housing of the motor 35. The second shaft 351 is rotatably connected to the second support 12 through a bearing. The output shaft of the motor 35 is coaxially fixed with the material tray 31 so that the material tray 31 can be rotated through the motor 35.

[0035] A servo electric cylinder 36 is rotatably connected between the motor 35 and the first bracket 11. The cylinder body of the servo electric cylinder 36 is rotatably connected to the first bracket 11 through the cooperation of the first shaft 361 and the bearing. The piston rod is rotatably connected to the housing of the motor 35 through the cooperation of the first shaft 361 and the bearing. The first shaft 351 and the second shaft 361 are parallel and both are perpendicular to the output shaft of the motor 35, so that the motor 35 can be driven to swing back and forth around the second shaft 351 by the extension and retraction adjustment of the servo electric cylinder 36.

[0036] like Figure 2 As shown, the material guiding assembly 40 includes a telescopic cylinder 43. The upper end of the telescopic cylinder 43 is fixed to the bottom of the hopper 20 and communicates with the discharge port 21. The lower end is close to the discharge area 33 so as to guide the rock powder discharged from the discharge port 21 through the telescopic cylinder 43.

[0037] like Figure 2 , Figure 7 As shown, a guide cover 41 is fixedly connected to the lower end of the telescopic cylinder 43. The guide cover 41 is fixed to the motor 35 by multiple sets of support frames 42. The upper crossbeam 421 of the support frame 42 is higher than the material plate 32 to avoid the support frame 42 interfering with the fixing of the material tray 31. The lower crossbeam 421 is fixed to the housing of the motor 35 to position the guide cover 41 through the support frame 42, so that the guide cover 41 is placed in the feeding area 33 and the lower edge abuts against the material tray 31 to avoid affecting the rotation of the material tray 31. At the same time, a sprinkling port 411 is opened on the side of the guide cover 41 away from the fixed ear plate of the spreading frame 10. The sprinkling port 411 is oriented towards the swing direction of the material tray 31 so that the rock powder is applied to a specific area through the sprinkling port 411.

[0038] like Figure 5 , Figure 6 As shown, a tamping rod 34 is coaxially fixed on the upper surface of the material tray 31. The upper end of the tamping rod 34 is inserted into the hopper 20 through the discharge port 21. When the material tray 31 swings back and forth, it drives the tamping rod 34 to swing in the hopper 20. The swinging tamping rod 34 stirs the rock powder in the hopper 20. When the tamping rod 34 swings with the material tray 31, it periodically stirs the rock powder at the bottom of the hopper 20 to break up the agglomerates and forces the rock powder near the discharge port 21 to flow loosely, which effectively solves the problem of blockage and agglomeration in the throwing of rock powder.

[0039] like Figure 6 As shown, the tamping rod 34 has a frustum-shaped structure that is narrow at the top and wide at the bottom. When the frustum-shaped tamping rod 34 swings, its gradually narrowing shape forms an uneven mixing trajectory in the hopper 20, resulting in a better mixing effect.

[0040] like Figure 3 As shown, a battery 50 is fixed to the bottom of the spreading frame 10 to provide power to the servo electric cylinder 36 and the motor 35.

[0041] Working principle: The fixed ear plate on the back of the spreading frame 10 is fixedly installed on the tractor frame by bolt and nut assembly. Rock powder is added into the hopper 20, and then the tractor is started to move the equipment. The motor 35 and servo electric cylinder 36 are powered on and run.

[0042] Rock powder is guided by telescopic cylinder 43 through discharge port 21 and then guided by guide cover 41 to discharge area 33. Motor 35 is powered on to drive material tray 31 and material plate 32 to rotate at high speed. After the rock powder in the discharge area 33 is placed in the area between the two material plates 32, under the action of centrifugation, when the rock powder reaches the position of sprinkling port 411, rock powder is applied to the soil.

[0043] During this process, the extension and retraction of the servo electric cylinder 36 drives the motor 35 and the material tray 31 to swing back and forth around the second shaft 351.
