Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment technology, specifically relating to a left-right lateral fertilizer spreader. Background Technology

[0002] Currently, fertilizer spreaders used in mechanized agricultural planting in my country generally have single-disc, double-disc centrifugal, and swing-arm structures. The fertilizer is spread directly behind the machine, characterized by surface application, with a typical spreading width of 20-30 meters. This type of fertilizer spreader requires field work and is suitable for applying crop management fertilizers (topdressing, heading fertilizer, etc.). Because the machine needs to work in the field, its wheels will compact the crops to a certain extent, causing damage and losses.

[0003] Currently, there is no mature technology or machinery for applying compound fertilizer to roadside trees, leisure and sightseeing lawns, and grapevines. Furthermore, existing fertilizer spreaders cannot accurately control the amount of fertilizer applied, resulting in excessive application of fertilizer and failure to fertilize as needed, thus failing to meet market demand. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a left-right lateral fertilizer spreader, which, by incorporating a material throwing disc assembly and a guide vortex housing, achieves high spreading efficiency and ensures accurate fertilizer application.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A lateral fertilizer spreader, comprising:

[0007] The suspension frame is connected to the traction machine;

[0008] A fertilizer bin is installed on a suspended frame, and a discharge port is provided at the bottom of the fertilizer bin;

[0009] A fertilizer application rate adjustment device is installed at the bottom of the fertilizer box and below the discharge port to control the amount of fertilizer discharged from the discharge port;

[0010] The material throwing device includes a material throwing disc assembly and a guide vortex housing. The guide vortex housing is mounted on a suspended frame and located below the fertilizer application rate adjustment device. The material throwing disc assembly is positioned inside the guide vortex housing. The guide vortex housing includes a vortex-shaped portion that is joined to form a vortex-shaped material discharge path. The vortex-shaped portion has a top opening and guide outlets at both ends. The material throwing disc assembly includes a fertilizer application flywheel, short spray blades, and long spray blades. Multiple sets of short and long spray blades are spaced apart and installed along the circumference of the fertilizer application flywheel.

[0011] The transmission assembly is mounted on the suspension frame, with its power input end connected to the drive shaft of the traction machine and its power output end connected to the material throwing device.

[0012] Furthermore, the short spraying blade has a "U" shaped structure, with the U-shaped opening of the short spraying blade facing to one side and connected to the fertilizer spreading flywheel by bolts.

[0013] Furthermore, the long spraying blade is composed of an outer wing, a middle wing, and an inner wing forming a U-shaped structure. The cross-sectional shape of the outer wing and the inner wing is arc-shaped. A V-shaped feeding port is connected to the inner wing. The U-shaped opening of the long spraying blade faces one side, and the V-shaped feeding port extends into the fertilizer spreading flywheel.

[0014] Furthermore, a cover is hinged to the end of the guide outlet.

[0015] Furthermore, the transmission assembly includes a gearbox, which is fixedly connected to the suspension frame; an input shaft, which is horizontally rotatably mounted inside the gearbox, and whose extended end is connected to the drive shaft of the traction machine; and an output shaft, which is vertically rotatably connected inside the gearbox, and whose extended end is connected to the throwing device.

[0016] Furthermore, the fertilizer flywheel has a central hole, through which the output shaft passes and is fixedly connected by a pin.

[0017] Furthermore, the output shaft extends through the throwing device into the inner cavity of the fertilizer box, and the shaft end is equipped with a stirrer that can automatically stir the fertilizer.

[0018] Furthermore, the fertilizer application rate adjustment device also includes an adjustment plate, an adjustment stationary plate, an adjustment handle, and a pulling rod. The adjustment plate and the adjustment stationary plate are sequentially arranged on the output shaft between the fertilizer box and the feeding device. The adjustment stationary plate is fixedly connected to the discharge port. A leakage port is opened on the adjustment stationary plate, and a leakage port with the same shape as the leakage port on the adjustment stationary plate is opened on the adjustment plate. The edge of the adjustment plate is connected to one end of the pulling rod. The other end of the pulling rod is connected to the adjustment handle. The adjustment handle is fixed on the suspension frame, and the adjustment handle drives the adjustment plate to rotate through the pulling rod.

[0019] Beneficial effects: This invention discloses a left-right lateral fertilizer spreader. By setting up a throwing disc assembly and a guide vortex housing, the reliability and stability of the fertilizer spreader are improved. It is also equipped with a fertilizer amount adjustment device, a mixer, and a cover, allowing adjustment of the fertilizer amount and width according to agronomic requirements. The addition of long and short throwing blades increases the contact between the blades and the fertilizer during the throwing process, resulting in more uniform spreading, increased fertilizer output, high spreading efficiency, and accurate fertilizer application. When fertilizer particles fly off the throwing blades, they are instantly spread on both sides under the action of the vortex section and guide outlet of the guide housing, improving the fertilizer spreading efficiency and quality of the fertilizer spreader.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-4 As shown, the present invention provides a left-right lateral fertilizer spreader, comprising:

[0035] Suspension frame 1, connected to the traction machine;

[0036] Fertilizer box 2 is installed on the hanging frame 1, and a discharge port is opened at the bottom of the fertilizer box 2;

[0037] The fertilizer application rate adjustment device 3 is installed at the bottom of the fertilizer box 2 and located below the discharge port, and is used to control the discharge rate of the discharge port;

[0038] Material throwing device 4, such as Figure 5-7 As shown, it includes a throwing disc assembly 41 and a guide vortex housing 42. The guide vortex housing 42 is mounted on the suspension frame 1 and located below the fertilizer application rate adjustment device 3. The throwing disc assembly 41 is positioned inside the guide vortex housing 42. The guide vortex housing 42 includes a vortex-shaped part 424 formed by opposite engagement. The vortex-shaped part 424 constitutes a vortex-shaped discharge material flow path. The vortex-shaped part 424 has a top opening 421 for receiving fertilizer from the fertilizer application rate adjustment device 3. Guide outlets 422 are opened at both ends of the vortex-shaped part 424. The throwing disc assembly 41 includes a fertilizer application flywheel 411, short throwing blades 412, and long throwing blades 413. Multiple sets of short throwing blades 412 and long throwing blades 413 are arranged at intervals and installed circumferentially along the fertilizer application flywheel 411.

[0039] The transmission component 5 is mounted on the suspension frame 1. Its power input end is connected to the drive shaft of the traction machine, and its power output end is connected to the throwing device 4. The transmission component 5 can be a chain drive, a belt drive, or a gear drive.

[0040] Based on the above embodiments, such as Figure 8-9 As shown, the short spraying blade 412 has a "U" shaped structure, with the U-shaped opening of the short spraying blade 412 facing to one side and connected to the fertilizer spreading flywheel 411 by bolts.

[0041] Based on the above embodiments, such as Figure 10-12 As shown, the long spraying blade 413 is composed of an outer wing, a middle wing, and an inner wing forming a U-shaped structure. The cross-sectional shape of the outer wing and the inner wing is arc-shaped. A V-shaped feeding port is connected to the inner wing. The U-shaped opening of the long spraying blade 413 faces to one side, and the V-shaped feeding port extends into the fertilizer spreading flywheel 411. The length of the long spraying blade 413 is 2.5 times that of the short spraying blade 412.

[0042] The short spraying blades 412 and long spraying blades 413 are arranged in six sets at intervals, with the U-shaped openings of the spraying blades facing the same direction. Fertilizer enters the fertilizer spreading flywheel 411 through the top opening 421. The rotation of the fertilizer spreading flywheel 411 drives the spraying blades to rotate, breaking the fertilizer into a discrete state. The long spraying blades 413 are designed with an arc shape to increase the contact between the blades and the fertilizer during the spraying process, resulting in more uniform spraying. Combined with the short spraying blades 412, this increases the amount of fertilizer thrown out, resulting in high spraying efficiency, ensuring accurate fertilizer application, and accelerating the throwing speed. When the fertilizer particles fly away from the spraying blades, they are sprayed on both sides under the action of the vortex section 424 and the guide outlet 422 of the guide housing 42. At the same time, a V-shaped feeding port is connected to the inner wing of the long spraying blades 413, allowing a small portion of fertilizer to be fed into the long spraying blades 413 through the V-shaped feeding port, ensuring the amount of fertilizer thrown out.

[0043] Based on the above embodiments, the end of the guide outlet 422 is hinged to a cover 423, which flips up and down to facilitate control of the fertilizer spreading width and stroke of the fertilizer spreader.

[0044] Based on the above embodiments, the transmission assembly 5 includes a gearbox 51, which is fixedly connected to the suspension frame 1; an input shaft 52, which is horizontally rotatably installed in the gearbox 51, and whose extended end is connected to the drive shaft of the traction machine; and an output shaft 53, which is vertically rotatably connected in the gearbox 51, and whose extended end is connected to the throwing device 4.

[0045] Based on the above embodiments, the fertilizer spreading flywheel 411 has a central hole, the output shaft 53 passes through the central hole, and is fixedly connected to it by a pin.

[0046] Based on the above embodiments, the output shaft 53 extends through the throwing device 4 into the inner cavity of the fertilizer box 2, and the shaft end is provided with a stirrer 6 that can automatically stir the fertilizer.

[0047] Based on the above embodiments, the fertilizer application rate adjustment device 3 further includes an adjustment plate, an adjustment plate 31, an adjustment handle 32, and a pulling rod 33. The adjustment plate and the adjustment plate 31 are sequentially arranged on the output shaft 53 between the fertilizer box 2 and the throwing device 4. The adjustment plate and the adjustment plate 31 do not rotate with the output shaft 53. The adjustment plate 31 is fixedly connected to the discharge port. A leakage port is opened on the adjustment plate 31. A leakage port with the same shape as the leakage port on the adjustment plate 31 is opened on the adjustment plate. The edge of the adjustment plate is connected to one end of the pulling rod 33. The other end of the pulling rod 33 is connected to the adjustment handle 32. The adjustment handle 32 is fixed on the suspension frame 1. The adjustment handle 32 drives the adjustment plate to rotate by pulling the connecting rod 33 to control the fertilizer output rate.

[0048] Working principle:

[0049] The frame 1 is suspended and connected to the traction machine, enabling it to travel and spread fertilizer. During travel, the drive shaft of the traction machine drives the throwing device 4 to rotate through the transmission component 5, causing the fertilizer in the fertilizer box 2 to be thrown out through the agitator 6 and the discharge port at the bottom, and then through the fertilizer spreading amount adjustment device 3.

[0050] Before the fertilizer spreading operation, the fertilizer spreader is adjusted according to the fertilizer amount and spreading width required at the fertilizer spreading location. Corresponding material outlets are opened on the adjusting plate 31 and the adjusting plate. The adjusting handle 32 pulls the connecting rod 33 to drive the adjusting plate to rotate, thereby adjusting the size of the material outlet and controlling the output amount. The end of the guide outlet 422 is hinged to a cover 423, which rotates up and down to facilitate the control of the spreading width and fertilizer flow direction of the fertilizer spreader.

[0051] The adjusting plate has a discharge port with the same shape as the discharge port on the adjusting plate 31. The edge of the adjusting plate is connected to one end of the pulling rod 33. The other end of the pulling rod 33 is connected to the adjusting handle 32. The adjusting handle 32 is fixed on the suspension frame 1. The adjusting handle 32 drives the adjusting plate to rotate by pulling the connecting rod 33, so as to control the amount of fertilizer discharged.

[0052] During application, when the power-driven fertilizer spreader flywheel 411 and output shaft 53 rotate at a certain speed, the fertilizer near the discharge port of fertilizer box 2 forms a relatively uniform density (loose) state under the action of agitator 6. Under the action of gravity, the fertilizer is evenly fed into the fertilizer spreader flywheel 411 through the discharge port. The rotation of the fertilizer spreader flywheel 411 drives the spreading blades to rotate. Under the action of the airflow generated by the rotation of the spreading blades and the spreading surface of the spreading blades, the fertilizer particles generate a certain centrifugal motion speed. When the fertilizer particles fly away from the spreading blades, they are spread on both sides under the action of the vortex section 424 of the guide housing 42 and the guide outlet 422. This provides technical and equipment support for the mechanization of compound fertilizer application for roadside trees, leisure roadside lawns, and grapes in my country.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this invention. The terms "front," "back," "left," and "right" used in the text are not specific and are primarily for illustrating the technical solution more intuitively, and do not constitute a limitation.
