Description

Technical Field

[0001] This utility model relates to the field of fertilizer applicator technology, specifically to a fertilizer applicator device. Background Technology

[0002] Fertilization is necessary for tobacco cultivation. The key points of fertilization can be summarized as "sufficient base fertilizer, accurate topdressing, foliar fertilizer supplementation, balanced nutrients, and avoidance of chlorine fertilizer." Compound fertilizer is usually the main component, supplemented with an appropriate amount of organic fertilizer (1000 kg / mu of well-rotted farmyard manure or 50 kg / mu of commercial organic fertilizer) to ensure comprehensive nutrient supply. 7-10 days after transplanting, apply seedling fertilizer (3.5 kg / mu of ammonium nitrate phosphate fertilizer), and 25-30 days later, apply seedling strengthening fertilizer (15 kg / mu of potassium sulfate). In the mid-to-late stages when potassium is deficient, foliar spray with a 0.2% potassium dihydrogen phosphate solution to prevent a decrease in tobacco quality.

[0003] Due to the small and scattered size of fields in mountainous and hilly areas, existing tobacco basal fertilizer application machinery is too large and unsuitable for these terrains. Therefore, the current application of tobacco basal fertilizer typically involves manually pushing fertilizer spreaders. These spreaders usually have discharge baffles at the outlet, requiring manual adjustment to close the outlet when changing lanes and to reopen it afterward. This frequent adjustment of the discharge baffles during fertilization is inconvenient, increases the workload for operators, and reduces fertilization efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a fertilizer application device that solves the problem that in the prior art, when the fertilizer application device changes rows, the discharge port needs to be manually closed and then manually opened again, which is inconvenient to use.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a fertilizer application device, comprising: A hopper, wherein a cavity is provided inside the hopper, and the top and bottom of the hopper are respectively provided with an inlet and an outlet communicating with the cavity; A moving mechanism includes a shaft and two rolling elements. The shaft is rotatably mounted on a hopper and passes through a discharge port. Both ends of the shaft extend to the outside of the hopper and are connected to the two rolling elements respectively. When the two rolling elements rotate in the forward direction, the shaft is rotating; when the two rolling elements rotate in the reverse direction, the shaft is stationary. An impeller is disposed inside the discharge port and fixedly connected to the shaft body. The impeller can close or open the discharge port.

[0006] In one embodiment, the rolling element includes a wheel body and a one-way bearing, wherein the inner ring of the one-way bearing is fixedly connected to one end of the shaft body, and the outer ring of the one-way bearing is fixedly connected to the center of the wheel body.

[0007] In one embodiment, the moving mechanism further includes two bidirectional bearings, which are respectively installed on opposite sides of the hopper, and the inner rings of the two bidirectional bearings are fixedly connected to the shaft.

[0008] In one embodiment, the impeller includes a sleeve and a plurality of blades, the sleeve being fixedly sleeved on the shaft, and the plurality of blades being fixedly disposed on the sleeve at intervals.

[0009] In one embodiment, the system further includes a cylinder with a material leakage hole at its bottom. The cylinder is mounted on the hopper, and the bottom of the cylinder extends into the cavity via the feed inlet.

[0010] In one embodiment, a partition is fixedly provided in the cavity, the partition dividing the cavity into a placement cavity and a feeding cavity located below the placement cavity, and the feeding cavity is connected to the placement cavity, the partition being supported at the bottom of the cylinder.

[0011] In one embodiment, the partition is at least one support rod fixed within the cavity.

[0012] In one embodiment, a push-pull rod is provided on one side of the top of the hopper, and a binding member is connected between the push-pull rod and the cylinder.

[0013] In one embodiment, a support member is provided on one side of the bottom of the hopper to prevent the hopper from tipping over.

[0014] In one embodiment, it further includes at least one flow control board, which is detachably installed in the hopper and corresponds to the discharge port, and the flow control board can reduce the discharge rate of the discharge port.

[0015] Compared with the prior art, the fertilizer application device provided by this utility model has an inlet and an outlet connected to the cavity at the top and bottom of the hopper, respectively. A shaft is rotatably mounted on the hopper and passes through the outlet. Both ends of the shaft extend to the outside of the hopper and are connected to two rolling elements. When the two rolling elements rotate in the forward direction, the shaft is rotating; when the two rolling elements rotate in the reverse direction, the shaft is stationary. An impeller is located in the outlet and fixed to the shaft. When the operator pulls the hopper, the two rolling elements rotate in the forward direction, driving the shaft to rotate the impeller, thus opening the outlet and allowing fertilizer to be discharged. When the operator pushes the hopper, the two rolling elements rotate in the reverse direction, keeping the impeller and shaft stationary, thus closing the outlet and preventing fertilizer from being discharged. This eliminates the need for manual opening and closing of the outlet, improving the convenience of the fertilizer application device. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] To address the inconvenience of manually closing and reopening the discharge port in existing fertilizer application devices when changing rows, this solution provides a fertilizer application device that allows the discharge port to be switched on or off by pushing or pulling the device.

[0019] Please see Figures 1-4 , Figures 1-4According to one embodiment of the present invention, a fertilizer application device includes a hopper 1, a moving mechanism 2, and an impeller 3. The hopper 1 has a cavity 1a inside, and the top and bottom of the hopper 1 are respectively located at an inlet and an outlet communicating with the cavity. The moving mechanism 2 includes a shaft 21 and two rolling elements 22. The shaft 21 is rotatably mounted on the hopper 1 and passes through the outlet. Both ends of the shaft 21 extend to the outside of the hopper 1 and are respectively connected to the two rolling elements 22. When the two rolling elements 22 rotate in the forward direction, the shaft 21 is in a rotating state. When the two rolling elements 22 rotate in the reverse direction, the shaft 21 is in a stationary state. The impeller 3 is located inside the outlet and is fixedly connected to the shaft 21. The impeller 3 can close or open the outlet.

[0020] In actual use, when fertilizing, fertilizer is placed in the cavity of the hopper 1. By pulling the hopper 1, the two rolling parts 22 rotate in the forward direction, thereby driving the impeller 3 on the shaft 21 to rotate, and the fertilizer can be discharged through the rotation of the impeller. When changing rows, by pushing the hopper 1 forward, the two rolling parts 22 rotate in the opposite direction, so that the coaxial body 21 and the impeller 3 are in a stationary state, and the discharge port is blocked and closed by the impeller, ensuring that no fertilizer is discharged when changing rows. It should be noted that the rolling element 22 is not limited to a specific structure. As long as the impeller 3 rotates with the shaft when the rolling element 22 rotates in the forward direction, and the impeller is stationary when the rolling element 22 rotates in the reverse direction, no further details will be provided here.

[0021] In one embodiment, the rolling element 22 includes a wheel body 221 and a one-way bearing 222. The inner ring of the one-way bearing 222 is fixedly connected to one end of the shaft body 21, and the outer ring of the one-way bearing 222 is fixedly connected to the center of the wheel body 221.

[0022] It is understandable that when the operator pulls the hopper 1 to move, the outer and inner rings of the one-way bearing 222 will not rotate relative to each other, that is, the shaft 21 can rotate synchronously with the two wheel bodies 221, thereby driving the impeller 3 to rotate; when the operator pushes the hopper 1 to move, the outer ring of the one-way bearing 222 rotates with the wheel body 221, that is, the shaft 21 and the impeller 3 remain stationary.

[0023] It should be noted that, in one embodiment, the moving mechanism 2 further includes two bidirectional bearings 223, which are respectively installed on opposite sides of the hopper 1, and the inner rings of the two bidirectional bearings 223 are fixedly connected to the shaft 21.

[0024] In one embodiment, the impeller 3 includes a sleeve 31 and a plurality of blades 32. The sleeve 31 is fixedly sleeved on the shaft 21, and the plurality of blades 32 are fixedly spaced on the sleeve 31. In this specific embodiment, the number of blades 32 is six, and the included angle between two adjacent blades 32 is 60°.

[0025] In addition, based on the above scheme, in order to increase the storage capacity of the silo 1, a cylinder 4 is placed in the cavity of the silo, wherein the bottom of the cylinder 4 is provided with a material leakage hole, the cylinder 4 is installed on the silo 1, and the bottom of the cylinder 4 extends into the cavity through the feed inlet.

[0026] It is understandable that when fertilizer is placed inside the cylinder 4, the fertilizer can enter the cavity through the leakage hole at the bottom of the cylinder 4.

[0027] It should be noted that, in one embodiment, a partition 11 is fixedly provided in the cavity, the partition 11 divides the cavity into a placement cavity and a feeding cavity located below the placement cavity, and the feeding cavity is connected to the placement cavity, the partition 11 is supported on the bottom of the cylinder 4.

[0028] The partition 11 is at least one support rod fixed in the cavity, which supports the bottom of the cylinder 4. The fertilizer in the cylinder 4 can enter the discharge cavity through the leakage hole. Specifically, the support rod is located in the middle of the hopper 1.

[0029] It should be noted that, based on the above scheme, in order to prevent the cylinder 4 from falling off the hopper and to facilitate the operator to push and pull the hopper, a push-pull rod 12 is specifically provided on one side of the top of the hopper 1, and a binding member 5 is connected between the push-pull rod 12 and the cylinder 4.

[0030] It is understood that the operator can use the binding member 5 to fix the cylinder 4 and the push-pull rod 12. The binding member 5 is not limited to a specific structure. In one embodiment, the binding member 5 can be a binding rope. The binding rope is wrapped around the cylinder 4 and the push-pull rod 12 and then knotted to fix the cylinder 4 and the push-pull rod 12.

[0031] Furthermore, based on the above solution, a support member 13 for preventing the silo 1 from tipping over is provided on one side of the bottom of the silo 1. In one embodiment, the support member 13 can be two vertical rods or U-shaped rods fixed to one side of the bottom of the silo 1. When the support member 13 contacts the ground, the support member 13 and the two wheels support the silo, which can prevent the silo from tipping over. Of course, in use, the silo needs to be tilted so that the support member 13 is separated from the ground, so that the silo can be moved.

[0032] Furthermore, in order to control the discharge volume at the outlet, a flow control plate 6 can be installed in the silo 1. It should be noted that by detachably installing at least one of the flow control plates 6 in the silo 1 and corresponding to the outlet, the flow control plate 6 can block part of the outlet to reduce the discharge volume.

[0033] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
