Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and more specifically, to a soil-laying device for a seedling production line. Background Technology

[0002] In modern large-scale seedling production, the soil-laying process after sowing in seedling trays is a key step to ensure seed germination and seedling root development. The uniformity of soil layering and the consistency of soil thickness directly affect the seedling survival rate and the uniformity of seedling growth.

[0003] In seedling production lines, when the seedling trays after sowing are transported to the soil-spreading device, the device delivers soil material onto the trays, primarily through gravity or a single roller distribution structure. This process can easily lead to uneven soil distribution, with some areas having excessively thick or thin soil layers, or gaps in the soil layer. Consequently, seed germination is inconsistent, and the rate of weak seedlings and seedling mortality increases. Therefore, we propose a soil-spreading device for seedling production lines. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a soil spreading device for a seedling production line to solve the technical problem of insufficient soil spreading uniformity, which affects the survival rate of seedlings.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a soil spreading device for a seedling production line, comprising a feeding mechanism and a leveling mechanism provided on the feeding mechanism. The feeding mechanism includes a base assembly and a storage assembly provided on the base assembly. The storage assembly includes a hopper, in which feeding screws are rotatably mounted at equal intervals. A discharge port is provided on the bottom surface of the hopper at the tail position of the feeding screws. A guide plate is provided at the bottom end of the hopper. The leveling mechanism includes mounting plates symmetrically arranged on the base assembly. A rotating brush is rotatably mounted between the mounting plates. A second motor for driving the rotating brush is provided on the side end of the mounting plates. A scraper is provided between the mounting plates behind the rotating brush.

[0006] Preferably, the guide plate is inclined, the guide plate is U-shaped, the tail of the guide plate is rectangularly open, the end of the guide plate is threaded with an adjusting bolt, the end of the adjusting bolt is rotatably mounted with a baffle, the inner wall of the tail of the guide plate is provided with a limiting groove, and both ends of the baffle are provided with sliders, which are slidably installed in the limiting groove.

[0007] Preferably, the base assembly includes symmetrically arranged base plates, with fixing holes equidistantly opened on the base plates, and uprights symmetrically arranged on the base plates.

[0008] Preferably, an elastic element is provided on the column, the elastic element is connected to the hopper, the elastic element includes a telescopic rod and a spring provided on the outside of the telescopic rod, and a vibration motor is provided at the center of the bottom surface of the hopper.

[0009] Preferably, a pulley is rotatably mounted on the back of the hopper, the pulley is connected to the shaft of the feeding screw, a transmission belt is provided between the pulleys, a first motor is provided on the back of the hopper, and the output shaft of the first motor is connected to the shaft of one of the pulleys.

[0010] Preferably, the scraper component includes a scraper section, a pressure section and a receiving section from bottom to top. The scraper section and the pressure section are each provided with an integral side baffle at their side ends. The pressure section is curved in an arc shape in the direction of the rotating brush, and the receiving section is curved in an arc shape in the opposite direction to the curvature of the pressure section.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a feeding screw and guide plate structure, ensures that the soil is pushed at a uniform speed along the length of the hopper by multiple feeding screws, avoiding excessive or missed feeding in certain areas. The elastic connection between the hopper and the column, combined with the bottom vibration motor, can prevent soil caking and blockage of the discharge port, and can also make the soil flow evenly on the guide plate through vibration, eliminating accumulation. The U-shaped inclined guide plate limits the soil flow range, and the combination of the end adjusting bolt and baffle can precisely control the soil output. With the help of the rotating brush to break up the clumps of soil, it not only ensures the uniformity of the soil on the seedling tray and ensures the seedling survival rate, but also can adapt to the soil thickness requirements of different seedling trays, solving the problem of insufficient soil uniformity that affects the seedling survival rate.

[0012] 2. This utility model also features a scraper structure. During seedling tray transport, the scraper part directly scrapes the soil on the seedling tray, filling depressions and removing protrusions. The arc-shaped pressure part lightly compacts the soil layer, preventing collapse after watering and ensuring close contact between the seeds and the soil. This ensures that the seeds can fully absorb water from the soil, promoting germination. Secondly, it improves the stability of the soil surface, preventing seedlings from falling over due to soil loosening after emergence. The side baffle prevents soil overflow, ensuring precise leveling. The reverse arc-shaped receiving part retains excess soil. When there is insufficient soil on the seedling tray, the soil on the receiving part can slide down to automatically replenish the local soil deficiency, achieving dynamic thickness balance. This lays the foundation for uniform sowing depth and further ensures seedling survival rate. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 6 As shown, this utility model relates to a soil-laying device for a seedling production line, including a feeding mechanism 100 and a leveling mechanism 200 provided on the feeding mechanism 100. The feeding mechanism 100 includes a base assembly and a storage assembly provided on the base assembly. The storage assembly includes a hopper 104, in which feeding screws 105 are rotatably mounted at equal intervals. A discharge port 1041 is provided on the bottom surface of the hopper 104 at the tail position of the feeding screws 105. A guide plate 109 is provided at the bottom end of the hopper 104. The leveling mechanism 200 includes mounting plates 201 symmetrically arranged on the base assembly. A rotating brush 202 is rotatably mounted between the mounting plates 201. A second motor 203 for driving the rotating brush 202 is provided on the side end of the mounting plates 201. A scraper 204 is provided between the mounting plates 201 behind the rotating brush 202. This utility model ensures uniform soil feeding and prevents clogging and clumping through a feeding screw 105 and a vibration motor 106, precise quantity control through a U-shaped guide plate 109 and an adjusting baffle 111, soil dispersion through a rotating brush 202, soil leveling and compaction through a scraper 204 and dynamic soil replenishment through a side baffle 2042, and soil overflow prevention. This significantly improves the uniformity and thickness consistency of soil spreading, adapts to different needs, and helps improve the survival rate of seedlings.

[0016] Specifically, the guide plate 109 is inclined and U-shaped, with a rectangular opening at its tail. An adjusting bolt 110 is threaded onto the end of the guide plate 109, and a baffle 111 is rotatably mounted on the end of the adjusting bolt 110. A limiting groove is provided on the inner wall of the tail of the guide plate 109, and sliders are provided at both ends of the baffle 111, slidingly mounted within the limiting groove. The inclined design of the guide plate 109 allows gravity to guide the soil flow smoothly, preventing accumulation. The U-shaped design limits the soil flow range, preventing side leakage. The baffle 111 is rotatably connected to the adjusting bolt 110, and the adjusting bolt 110 adjusts the position of the baffle 111 via threaded transmission, achieving controllable soil output.

[0017] Furthermore, the base assembly includes symmetrically arranged base plates 101, with fixing holes evenly spaced on the base plates 101, and uprights 102 symmetrically arranged on the base plates 101. The base plates 101 facilitate the overall installation and fixing of the device onto the conveyor device of the seedling tray production line.

[0018] It is worth noting that an elastic element 103 is provided on the column 102, which is connected to the hopper 104. The elastic element 103 includes a telescopic rod and a spring on the outside of the telescopic rod. A vibration motor 106 is provided at the center of the bottom surface of the hopper 104. The connection between the elastic element 103 and the hopper 104 achieves a flexible connection between the hopper 104 and the column 102. The elastic element 103 includes a telescopic rod and a spring on the outside of the telescopic rod. The telescopic rod ensures the extension and contraction guidance, and the spring provides elastic buffering force. When the device is conveying soil, the vibration motor 106 works to make the hopper 104 vibrate, which can prevent the soil from clumping and clogging in the hopper 104 and ensure smooth feeding. When the soil is conveyed to the guide plate 109, because the guide plate 109 is inclined, the vibration force can make the soil material be conveyed forward evenly, and finally discharged from the tail of the guide plate 109 onto the seedling tray.

[0019] It is worth noting that a pulley 107 is rotatably mounted on the back of the hopper 104. The pulley 107 is connected to the shaft of the feeding screw 105, and a drive belt is provided between the pulleys 107. A first motor 108 is located on the back of the hopper 104, and the output shaft of the first motor 108 is connected to the shaft of one of the pulleys 107. When the first motor 108 operates, it can rotate one of the pulleys 107, and under the action of the drive belt, it can make the other pulleys 107 rotate synchronously, thereby causing multiple feeding screws 105 to rotate for soil feeding.

[0020] It is worth noting that the scraper component 204 includes, from bottom to top, a scraper portion 2041, a pressure application portion 2043, and a receiving portion 2044. Both the scraper portion 2041 and the pressure application portion 2043 are provided with an integral side baffle portion 2042 at their side ends. The pressure application portion 2043 is bent into an arc shape in the direction of the rotating brush 202, and the receiving portion 2044 is bent into an arc shape in the opposite direction to the bending of the pressure application portion 2043. The seedling trays are conveyed on the conveyor belt of the conveying device and pass through the soil spreading device. The feeding mechanism 100 delivers granular soil to the seedling trays. As the seedling trays continue to be conveyed, the scraper part 2041 of the scraper 204 can scrape the soil on the seedling trays to level it. Secondly, the pressure part 2043, due to its arc-shaped design, can apply pressure to the seedling trays during conveying, which can slightly compact the soil and improve the soil density and flatness. The side baffle part 2042 can not only push the soil on the upper edge of the seedling trays to the seedling trays, but also prevent soil from overflowing from both sides of the scraper 204, ensuring accurate leveling. During the scraping process of the scraper part 2041, when the soil height exceeds the pressure part 2043, in order to prevent the soil from being over-compacted, the excess soil will be retained on the receiving part 2044. When there is too little soil on the seedling trays, the soil on the receiving part 2044 will slide down to the seedling trays to fill the soil gaps and ensure the soil thickness on the seedling trays.

[0021] Working Principle: This embodiment provides a soil-laying device for a seedling production line. In use, the device is first fixed to the conveying device of the seedling tray production line via the fixing holes on the base plate 101, ensuring precise alignment between the device and the seedling tray conveying path. Then, soil material to be laid is added to the hopper 104. After starting the device, the first motor 108 begins operation, its output shaft driving the connected pulley 107 to rotate. Under the transmission of the drive belt, the other pulleys 107 connected to the shaft of the feeding screw 105 rotate synchronously, thereby driving multiple feeding screws 105 equidistantly installed in the hopper 104 to rotate uniformly in the same direction. During the rotation of the feeding screws 105, they continuously push the soil in the hopper 104 towards the tail. Finally, the soil... Soil falls from the bottom of the hopper 104 to the outlet 1041 at the tail of the feeding screw 105 onto the inclined U-shaped guide plate 109 below. Simultaneously, the vibration motor 106 at the center of the bottom of the hopper 104 starts. Because the hopper 104 is flexibly connected to the column 102 via an elastic element 103 (composed of a telescopic rod and an outer spring), the vibration force generated by the vibration motor 106 can cause the hopper 104 to vibrate slightly. This prevents soil from clumping and blocking the outlet 1041 within the hopper 104, and also allows the soil on the guide plate 109 to flow smoothly along the inclined direction through vibration transmission, preventing local accumulation. Workers can adjust the amount of soil needed for seedling cultivation by rotating the adjusting bolt 110 at the end of the guide plate 109, using threaded transmission to drive the baffle 1... 11. Slide along the limiting groove at the tail of the guide plate 109 to adjust the distance between the baffle 111 and the rectangular opening at the tail of the guide plate 109, so as to achieve precise control of the soil output. The soil is guided by the guide plate 109 and falls evenly into the seedling tray on the lower conveying device. During the process of the soil falling into the seedling tray, the second motor 203 starts to drive the rotating brush 202 between the mounting plates 201 to rotate. The rotating brush 202 can break up the spread soil, break up any possible clumps, and make the soil distribution more even. Then the seedling tray continues to move to the scraper 204. The scraper part 2041 of the scraper 204 is in contact with the surface of the seedling tray to scrape the soil, remove the protrusions, and fill the depressions. At the same time, the scraper part 2041 and the pressure part 204... The integrated side baffles 2042 on the three sides prevent soil from overflowing from both sides of the scraper and push the soil at the edge of the seedling tray into the tray, ensuring precise leveling. The arc-shaped pressure application part 2043 applies slight pressure to the soil during the seedling tray transport process, making the soil layer uniform in density and preventing local collapse after watering. The receiving part 2044, which is arc-shaped in the opposite direction to the pressure application part 2043, will leave excess soil above the pressure application part 2043 when the scraper part 2041 scrapes the soil. When there is too little soil in a certain area of ​​the seedling tray, the soil on the receiving part 2044 will naturally slide down to the corresponding position to replenish it. Finally, the soil in the seedling tray is evenly thick, flat and with appropriate density, ensuring the subsequent seed germination and seedling growth.
