Description

Technical Field

[0001] This utility model relates to the field of farmland restoration technology, and in particular to a fertilizer spreading device for farmland restoration. Background Technology

[0002] Farmland is land cultivated by humans for growing crops. It is the foundation of agricultural production and is not only the main source of agricultural products such as grains, vegetables, and fruits, but also an important part of the rural economy and farmers' lives. Long-term cultivation, excessive use of chemical fertilizers and pesticides, and unreasonable irrigation methods can lead to problems such as declining soil fertility, soil compaction, salinization, and acidification. Farmland restoration can improve soil quality, increase soil fertility and water retention capacity through measures such as applying organic fertilizers, crop rotation, and soil conditioners. During the farmland restoration process, fertilizer spreading devices are used to spread organic fertilizers.

[0003] Existing fertilizer application equipment for farmland remediation still has some problems. Current application equipment can only apply granular fertilizers and cannot apply some solution-based fertilizer enhancers, which limits the means of fertilizing farmland. Therefore, those skilled in the art provide a fertilizer application equipment for farmland remediation to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fertilizer spreading device for farmland restoration. By setting up a spreading structure, it is possible to spread granular fertilizer and solvent-based fertilizer simultaneously, thereby increasing the diversity of fertilization and improving the efficiency of fertilization of farmland.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fertilizer spreading device for farmland restoration, comprising a support frame, a spreading structure provided at the front center of the upper end face of the support frame, a scraper structure provided at the rear center of the lower end face of the support frame, and wheels rotatably connected to the lower front end of both side walls of the support frame. The spreading structure includes a storage box, a liquid storage tank is provided on the rear end face of the storage box, a discharge port is fixedly connected to the center of the lower end face of the storage box, a second electric gate valve is fixedly connected to the output end of the discharge port, a first electric gate valve is fixedly connected to the center of the lower end face of the liquid storage tank, a leak pipe is fixedly connected to the output end of the first electric gate valve, and multiple leak holes are arranged horizontally at the center of the lower end face of the leak pipe. By controlling the opening of the first electric gate valve, the liquid inside the storage tank enters the leak pipe through the first electric gate valve and drips into the farmland through multiple leak pipes. This facilitates the simultaneous application of granular fertilizer and solvent-based fertilizer, increasing the diversity of fertilization and improving the efficiency of fertilization of farmland.

[0006] Furthermore, a connecting rod is fixedly connected to the lower center of the storage box, and multiple rubber rods are horizontally arranged and fixedly connected to the center of the lower end face of the connecting rod. A vibration motor is fixedly connected to the lower end face of each of the multiple rubber rods, and a vibration transmission rod is fixedly connected to the lower outer wall of each vibration motor. Through the above technical solution, the opening of the second electric gate valve and the start of multiple vibration motors are controlled. The multiple vibration motors generate vibration by generating centrifugal force based on the rotational motion of eccentric mass or eccentric block. The vibration is transmitted to the vibration transmission rod, and the generated vibration vibrates the fertilizer particles at the inlet of the discharge port, so that they fall more evenly from the discharge port for spreading.

[0007] Furthermore, both the material storage tank and the liquid storage tank are rotatably connected to a lid at the center of their upper surfaces; The above technical solution prevents foreign objects from entering the storage tank and liquid tank after the lid is closed.

[0008] Furthermore, guide grooves are fixedly connected to both the front and rear ends of the lower inner wall of the storage tank and the front and rear ends of the lower inner wall of the liquid storage tank. The above technical solutions prevent fertilizer from accumulating inside the storage tank and also prevent solvent residue inside the liquid storage tank.

[0009] Furthermore, the scraper structure includes three connecting columns, which are arranged laterally and fixedly connected to the lower end face of the bracket. A base plate is fixedly connected to the lower end of the three connecting columns. A plurality of scraper rods are provided on the lower end face of the base plate. The plurality of scraper rods are divided into two groups, and the two groups of scraper rods are arranged one in front of the other on the lower end face of the base plate, with the two scraper rods arranged alternately. The above technical solution uses multiple scrapers to cut the ground, making it easier for solvents and fertilizer particles to penetrate into the soil of farmland and reducing the volatilization of solvents and fertilizer particles.

[0010] Furthermore, three connecting seats are fixedly connected in a triangular arrangement at the center of the front end face of the bracket; The above technical solution connects the equipment to the tractor via three connecting seats, which is a common technical method in existing tractor-based agricultural equipment and will not be elaborated on further here.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the fertilizer spreading equipment for farmland restoration controls the opening of the first electric gate valve. The liquid inside the storage tank enters the inside of the leak pipe through the first electric gate valve and drips into the farmland through multiple leak pipes. This facilitates the simultaneous spreading of granular fertilizer and solvent-based fertilizer, increases the diversity of fertilization, and improves the efficiency of fertilization of farmland.

[0012] 2. In this utility model, the opening of the second electric gate valve and the starting of multiple vibration motors are controlled. The multiple vibration motors generate vibration by generating centrifugal force based on the rotational motion of eccentric mass or eccentric block. The vibration is transmitted to the vibration transmission rod. The generated vibration vibrates the fertilizer particles at the inlet of the discharge port, making it easier for them to fall more evenly from the discharge port for spreading. After spreading, multiple scrapers cut the ground, making it easier for the solvent and fertilizer particles to penetrate into the soil of the farmland and reducing the volatilization of the solvent and fertilizer particles.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-4 One embodiment of this utility model is a fertilizer spreading device for farmland restoration, which includes a support 1, a spreading structure 2 at the front center of the upper end face of the support 1, a scraper structure 3 at the rear center of the lower end face of the support 1, and wheels 4 rotatably connected to the lower front end of both side walls of the support 1.

[0017] like Figure 1 , 2 As shown in Figures 3 and 4, the spreading structure 2 includes a storage tank 201, a liquid storage tank 202 at the rear end of the storage tank 201, a discharge port 204 fixedly connected to the center of the lower end of the storage tank 201, a second electric gate valve 213 fixedly connected to the output end of the discharge port 204, a first electric gate valve 207 fixedly connected to the center of the lower end of the liquid storage tank 202, and a leak pipe 205 fixedly connected to the output end of the first electric gate valve 207. Multiple leak holes 206 are arranged horizontally at the center of the lower end of the leak pipe 205. By controlling the opening of the first electric gate valve 207, the liquid inside the liquid storage tank 202 enters the leak pipe 205 through the first electric gate valve 207 and drips into the farmland through the multiple leak pipes 205. This facilitates the simultaneous spreading of granular fertilizer and solvent-based fertilizer, increasing the diversity of fertilization and improving the efficiency of fertilization of the farmland.

[0018] A connecting rod 208 is fixedly connected to the lower center of the storage bin 201. Multiple rubber rods 209 are horizontally arranged and fixedly connected to the center of the lower end face of the connecting rod 208. Vibration motors 210 are fixedly connected to the lower end faces of the multiple rubber rods 209. Vibration transmission rods 211 are fixedly connected to the lower outer wall of each vibration motor 210. The second electric gate valve 213 is opened and the multiple vibration motors 210 are started. The multiple vibration motors 210 generate vibration by generating centrifugal force based on the rotational motion of the eccentric mass or eccentric block. The vibration is transmitted to the vibration transmission rods 211. The generated vibration vibrates the fertilizer particles at the inlet position of the discharge port 204, so that they fall more evenly from the discharge port 204 for spreading.

[0019] Both the material storage tank 201 and the liquid storage tank 202 are rotatably connected to a cover 203 at the center of their upper surfaces. After the cover 203 is closed, foreign objects are prevented from entering the material storage tank 201 and the liquid storage tank 202.

[0020] Guide grooves 212 are fixedly connected to both the front and rear ends of the lower inner wall of the storage tank 201 and the front and rear ends of the lower inner wall of the liquid storage tank 202 to prevent fertilizer from accumulating inside the storage tank 201 and to prevent solvent residue inside the liquid storage tank 202.

[0021] like Figure 1 , 2 As shown in Figure 3, the scraper structure 3 includes three connecting columns 301, which are arranged horizontally and fixedly connected to the lower end face of the support 1. The lower end of the three connecting columns 301 is fixedly connected to a base plate 302. The lower end face of the base plate 302 is provided with multiple scraper rods 303, which are divided into two groups. The two groups of scraper rods 303 are arranged one after the other on the lower end face of the base plate 302, and the two scraper rods 303 are staggered. The ground is cut by the multiple scraper rods 303, so that the solvent and fertilizer particles can penetrate into the ground of the farmland more easily and reduce the volatilization of the solvent and fertilizer particles.

[0022] Three connecting seats 5 are fixedly connected in a triangular arrangement at the center of the front end face of the bracket 1. The equipment is connected to the tractor through the three connecting seats 5. This is a common technical means in existing tractor-based agricultural equipment, and will not be elaborated on here.

[0023] Working principle: In use, open both lids 203, place granular fertilizer into the storage box 201, add fertilizer solvent into the liquid storage box 202, and then close both lids 203. Connect the tractor via the connecting seat 5. The tractor drives the support 1 to move. During the movement, control the second electric gate valve 213 to open and start multiple vibration motors 210. The multiple vibration motors 210 generate vibration by generating centrifugal force based on the rotational motion of eccentric mass or eccentric block, and transmit the vibration to the vibration transmission rod 211. The existing vibration motor 210 uses common techniques, which will not be elaborated on here. The vibration generated vibrates the fertilizer granules at the inlet of the discharge port 204, making it easier for them to fall more evenly from the discharge port 204 for spreading. The control of the first electric gate valve 207 opens the liquid inside the storage tank 202 and enters the leakage pipe 205 through the first electric gate valve 207. The liquid drips into the farmland through multiple leakage pipes 205, which facilitates the simultaneous spreading of granular fertilizer and solvent-based fertilizer, increases the diversity of fertilization and improves the efficiency of fertilization of farmland.

[0024] After sowing, the ground is cut by multiple scrapers 303, making it easier for the solvent and fertilizer particles to penetrate into the soil of the farmland and reducing the volatilization of the solvent and fertilizer particles.

[0025] The equipment also includes an integrated controller. The integrated controller receives signals from various components through input ports. After processing, these signals serve as the basis for control decisions. The integrated controller then uses a control algorithm to process the input signals and generates control outputs according to predetermined rules. Based on the results of the control algorithm, the integrated controller sends signals to the actuators through the output ports. The integrated controller can coordinate the work of various components and continuously monitor the operating status of each component, adjusting the control strategy in a timely manner based on feedback to cope with possible changes or anomalies. This solution is a commonly used technical method in the prior art and will not be elaborated on further here.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
