Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural equipment technology, and in particular relates to a fertilizer applicator for granular fertilizer. Background Technology
[0002] In traditional agricultural production, fertilization is necessary to ensure crops receive sufficient nutrients during their growth. Common fertilizers include liquid fertilizers and granular fertilizers. Granular fertilizers are mostly applied manually, while large fertilizer spreaders are used for large-scale farmland operations. Some farmlands are not suitable for large fertilizer spreaders and require manual fertilization. However, manual spreading is inefficient, and fertilizer needs to be applied close to the roots of the crops, often requiring bending over, resulting in high labor intensity and fatigue. Therefore, small fertilizer spreaders have emerged to assist in fertilization. However, existing fertilizer spreaders require manual control of the fertilizer amount, making it difficult to ensure uniform application. Furthermore, these small fertilizer spreaders typically need to be manually moved during operation, which is inconvenient and increases the burden on operators. Utility Model Content
[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a granular fertilizer applicator that is simple to operate, easy to carry and move, and can realize quantitative fertilization.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A fertilizer applicator for granular fertilizer, comprising:
[0006] A material cylinder, wherein a feeding port is provided at the top and a discharging port is provided at the bottom;
[0007] A feeding assembly includes a feeding box, a feeding block, a moving rod, and a pull rod. The feeding box has a feeding channel on its top left side that communicates with the discharge port, and a feeding port on its bottom right side. The feeding block includes a plug, a receiving port, and a baffle arranged from left to right. The feeding block is slidably positioned within the feeding box. When the feeding block is on the left side, the receiving port connects with the feeding channel; when the feeding block is on the right side, the plug blocks the feeding channel, and the receiving port connects with the feeding port. The moving rod is horizontally positioned, with one end inserted into the feeding box and connected to the baffle, and the other end passing through the right side wall of the feeding box to the outside and connecting to the lower end of the vertically positioned pull rod. A spring is fitted onto the moving rod, with one end abutting against the baffle and the other end abutting against the right inner side wall of the feeding box.
[0008] The discharge pipe is vertically arranged, and its upper end is connected to the discharge port;
[0009] The frame supports the material cylinder, and the bottom of the frame is equipped with rollers and the top is equipped with a handle.
[0010] The feed cylinder is used to store fertilizer; fertilizer granules fall into the feed channel through the discharge port; when the feed block is not pulled, it is located on the left side under the action of the spring, and the receiving port connects with the feed channel, allowing the granules in the feed channel to fall into the receiving port; pulling the lever to the right moves the feed block to the right, moving the receiving port to the feed port, which is a through-hole structure, allowing the fertilizer granules in the receiving port to fall into the feed port and down through the discharge pipe, completing the application. At this point, the plug blocks the feed channel. Releasing the lever causes the feed block to return to its original position under the action of the spring; the amount of fertilizer applied each time is the volume of the receiving port. When a large amount of fertilizer needs to be applied, the lever can be pulled multiple times at the same application point to increase the amount of fertilizer applied; the frame supports the entire device and is equipped with a handle and rollers, allowing the fertilizer applicator to be moved by pushing the handle.
[0011] Furthermore, a rotating handwheel is provided at the center of the top outer end face of the material cylinder; a vertically arranged rotating rod with helical blades is provided in the inner cavity of the material cylinder, the upper end of the rotating rod is connected to the rotating handwheel, and the lower end of the rotating rod extends into the discharge port.
[0012] The design of the handwheel and rotating rod is to prevent the granular fertilizer in the hopper from accumulating and forming bridging, which would affect the feeding process. By turning the handwheel, the rotating rod can be rotated to solve the bridging problem and allow the fertilizer to fall smoothly.
[0013] Furthermore, a positioning block is provided on the inner top plate on the right side of the feeding box. When the receiving port is connected to the feeding port, the right side of the baffle plate abuts against the positioning block.
[0014] Limit the movement distance of the feeding block to ensure more accurate docking between the receiving port and the feeding port.
[0015] Furthermore, the front and rear inner walls of the feeding box are provided with left and right sliding tracks, and the front and rear side walls of the feeding block are provided with sliders that slide on the sliding tracks.
[0016] Furthermore, the discharge pipe includes a pipe body and a large-mouthed hopper installed at the bottom of the pipe body; the upper end of the pipe body is connected to the discharge port; the inner cavity of the hopper is provided with an inner cover shell arranged concentrically therewith, and a discharge channel is formed between the outer side wall of the inner cover shell and the inner side wall of the hopper; the inner cover shell is connected to the hopper via a connecting rod.
[0017] The fertilizer falls down the discharge pipe to the hopper. Due to the presence of the inner hopper, the fertilizer falls down along the discharge channel formed between the inner hopper and the hopper, forming a circle around the crop, which can adapt to the different fertilization needs of different crops.
[0018] Furthermore, the frame includes a support base and legs located at the lower end of the support base; the material cylinder is mounted on the support base, and the discharge pipe is suspended above the ground; there are four legs, including two long legs on the right side and two short legs on the left side; the bottom of the long legs is provided with rollers.
[0019] Hold the handle and tilt the device slightly to the right, lifting the short support leg off the ground. Push the device to move it to the designated position, then straighten it. The short support leg will then support the device on the ground, serving as both a support and a brake.
[0020] Furthermore, the handle is covered with a non-slip sleeve.
[0021] Compared with the prior art, the granular fertilizer applicator of this utility model has the following advantages:
[0022] The granular fertilizer applicator of this utility model is equipped with a feeding component. By pulling the lever, the feeding block moves, thereby connecting the receiving port with the feeding port. The fertilizer in the receiving port falls into the feeding port and then flows down through the discharge pipe to complete the application. This enables quantitative fertilization and ensures uniform fertilizer application. A plug is also included to block the feeding channel during feeding, preventing accidental discharge. The structure is reasonably designed and easy to operate. Operators only need to pull the lever to complete the quantitative fertilization operation, effectively reducing workload. The frame eliminates the need for manual weight-bearing, making it easy to carry and move. Attached Figure Description
