Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer application technology, specifically a fertilizer crushing and spreading device for saline-alkali land. Background Technology
[0002] Saline-alkali land refers to land containing excessive soluble salts or alkaline substances, which leads to the deterioration of the soil's physical and chemical properties and affects the normal growth of crops. Currently, fertilizers are applied to saline-alkali land to improve the soil environment.
[0003] Current fertilizer application devices require a crushing structure because fertilizer tends to clump. However, during the crushing process, some clumps accumulate at the bottom and break off, and unidirectional stirring is insufficient to fully crush the fertilizer. Furthermore, the inner walls of the device are often difficult to clean and dry after cleaning. Therefore, a fertilizer crushing and application device for saline-alkali land is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a fertilizer crushing and spreading device for saline-alkali land to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer crushing and spreading device for saline-alkali land, comprising a base plate, rollers mounted on the lower surface of the base plate, a housing connected to the right end of the upper surface of the base plate, a control panel connected to the top of the housing, a push rod provided on the right side of the housing, the bottom end of the push rod connected to the base plate, a mounting frame connected to the left end of the upper surface of the base plate, a connecting plate provided on the inner side of the mounting frame, an opening at the bottom of the connecting plate, and a housing connected to the rear inner wall of the connecting plate via a motor, multiple discharge ports equally spaced on the outer surface of the housing, a filter screen installed inside the discharge ports, an anti-fouling mechanism connected to the inner wall of the housing, and a bidirectional stirring mechanism provided inside the housing.
[0006] Preferably, the inner walls of the left and right ends of the mounting bracket are respectively connected to a lead screw and a guide rod, and the outer surfaces of the lead screw and the guide rod are fitted with connecting blocks. The opposing surfaces of the two connecting blocks are rotatably connected to the left and right ends of the connecting plate, respectively.
[0007] Preferably, the front surface of the connecting plate is provided with a circular groove, and the outer shell is recessed inside the circular groove, and the front surface of the outer shell is connected to an end cap.
[0008] Preferably, the anti-fouling mechanism includes an inner plate, a mounting block, and a magnet. Multiple inner plates are provided, and all of the inner plates are embedded in and connected to the inner wall of the outer shell. The mounting block is connected to one end surface of each of the inner plates near the inner wall of the outer shell, and a magnet is provided on the outer side of the mounting block.
[0009] Preferably, all of the inner plates are arc-shaped and their radii of curvature are the same as those of the outer shell, and the inner plates are arranged sequentially between adjacent discharge ports.
[0010] Preferably, the bidirectional stirring mechanism includes a first stirring rod, a second stirring rod, and protruding rods. The first stirring rod is located in the middle of the inner part of the outer shell, and the front end surface of the first stirring rod is connected to a motor installed on the outer surface of the end cover. The second stirring rod is located directly behind the first stirring rod and is fixedly connected to the inner rear wall of the outer shell. Multiple protruding rods are evenly spaced on the facing surfaces of the first and second stirring rods, and the protruding rods on the first and second stirring rods are staggered.
[0011] Preferably, the left and right end surfaces of the connecting plate are movably connected to fixing plates, and bolts are inserted inside the fixing plates.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This fertilizer crushing and spreading device for saline-alkali land has a rotatable outer shell and multiple discharge ports. The rotation of the outer shell changes the position of each discharge port in real time, so that the clumps of fertilizer that are not fully crushed will fall due to gravity and will not accumulate at the discharge port and escape from the crushing of the mixing rod.
[0014] 2. This saline-alkali land fertilizer crushing and spreading device is equipped with a bidirectional stirring mechanism, which includes a first stirring rod, a second stirring rod, and a convex rod. The second stirring rod rotates clockwise with the outer shell, while the first stirring rod rotates independently counterclockwise driven by a motor. This allows the clumps of fertilizer to be fully crushed through a combination of factors, including the squeezing force when the convex rods approach each other, the collision force generated by the high-speed rotation of the stirring rods throwing the fertilizer against the inner wall of the outer shell, and the collision between the stirring rods themselves and the fertilizer.
[0015] 3. This fertilizer crushing and spreading device for saline-alkali land has an anti-fouling mechanism, which includes an inner plate, a mounting block, and a magnet. By utilizing the connection between the inner plate and the inner wall of the outer shell, the fertilizer does not directly contact the annular inner wall of the outer shell. During cleaning, the inner plate can be pulled out for thorough cleaning, thus solving the problem of difficulty in rinsing the annular inner wall of the outer shell. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] like Figures 1 to 5As shown, the fertilizer crushing and spreading device for saline-alkali land in this embodiment includes a base plate 1. Rollers are installed on the lower surface of the base plate 1. A housing 2 is connected to the right end of the upper surface of the base plate 1, and a control panel 3 is connected to the top of the housing 2. Various electrical components supporting the normal operation of the control panel 3 are installed inside the housing 2. The control panel 3 can be used to control the operation of various motors on the device. The specific installation method and circuit connection structure of the control panel 3 are preset by relevant technicians in advance. A push rod 4 is provided on the right side of the housing 2, and the bottom end of the push rod 4 is connected to the base plate 1. The user pushes the push rod 4 to move the device. A mounting frame 5 is connected to the left end of the upper surface of the base plate 1, and a connecting plate is provided on the inner side of the mounting frame 5. 9. The bottom of the connecting plate 9 is provided with an opening, and the inner wall of the rear end of the connecting plate 9 is connected to the outer shell 10 through a motor. The motor controls the outer shell 10 to rotate in a clockwise direction. Multiple discharge ports 11 are opened at equal angles on the outer surface of the outer shell 10, and a filter screen 12 is installed inside the discharge port 11. The fertilizer inside the outer shell 10 can be spilled out through the discharge port 11, while the filter screen 12 can block the incompletely crushed clumps of fertilizer. The inner wall of the outer shell 10 is connected to an anti-fouling mechanism. By setting the anti-fouling mechanism, the inside of the outer shell 10 can be protected from contamination. The inside of the outer shell 10 is provided with a bidirectional stirring mechanism, which can fully crush the clumps of fertilizer inside the outer shell 10.
[0025] Specifically, the inner walls of the left and right ends of the mounting frame 5 are respectively connected to a lead screw 6 and a guide rod 7. The outer surfaces of the lead screw 6 and the guide rod 7 are fitted with connecting blocks 8. The opposing surfaces of the two connecting blocks 8 are rotatably connected to the left and right ends of the connecting plate 9. The top of the lead screw 6 is connected to a motor. By controlling the rotation of the lead screw 6, the connecting blocks 8 can be controlled to slide up and down, thereby causing the connecting plate 9 and the outer shell 10 to slide up and down. Thus, when the connecting plate 9 and the outer shell 10 are rotated horizontally, they can be controlled to move to the bottom, making it convenient to add clumped feed.
[0026] Furthermore, the front surface of the connecting plate 9 is provided with a circular groove, and the outer shell 10 is recessed inside the circular groove. The front surface of the outer shell 10 is connected to an end cap 19. By providing the circular groove, the outer shell 10 can be installed inside the connecting plate 9, and fertilizer can be applied through its bottom opening. By opening the end cap 19, clumped fertilizer can be added into the outer shell 10, and its interior can also be cleaned.
[0027] Furthermore, the anti-fouling mechanism includes an inner plate 13, a mounting block 14, and a magnet 15. Multiple inner plates 13 are provided, and all of the inner plates 13 are embedded in the inner wall of the outer shell 10. The mounting block 14 is connected to one end surface of each inner plate 13 near the inner wall of the outer shell 10, and a magnet 15 is provided on the outer side of the mounting block 14. The inner plates 13 are made of iron and are inserted into the inner wall of the outer shell 10 by the mounting block 14 and are fixed by the magnet 15. The multiple inner plates 13 cover all parts of the annular inner wall of the outer shell 10 except for the discharge port 11. In this way, the inner plates 13 can prevent fertilizer from contaminating the inner wall of the outer shell 10, and the inner plates 13 can be removed for easy cleaning.
[0028] Furthermore, the multiple inner plates 13 are all arc-shaped, and their radii of curvature are the same as those of the outer shell 10. The multiple inner plates 13 are arranged sequentially between adjacent discharge ports 11, thus ensuring that the inner plates 13 can be perfectly connected to the inner wall of the outer shell 10.
[0029] Furthermore, the bidirectional mixing mechanism includes a first mixing rod 16, a second mixing rod 17, and protruding rods 18. The first mixing rod 16 is located in the middle of the interior of the outer shell 10, and the front end surface of the first mixing rod 16 is connected to a motor mounted on the outer surface of the end cover 19. The second mixing rod 17 is located directly behind the first mixing rod 16 and is fixedly connected to the inner rear wall of the outer shell 10. Multiple protruding rods 18 are evenly spaced on the facing surfaces of the first mixing rod 16 and the second mixing rod 17, and the protruding rods 18 on the first mixing rod 16 and the second mixing rod 17 are staggered. The motor used to control the rotation of the outer shell 10 controls the outer shell 10 to rotate clockwise. At this time, the second mixing rod 17 will also rotate clockwise. Subsequently, the motor on the end cover 19 controls the first mixing rod 16 to rotate counterclockwise, thereby realizing bidirectional mixing. The fertilizer is fully crushed by means of the squeezing when the protruding rods 18 approach each other, the collision generated by the high-speed rotation of the mixing rods throwing the fertilizer against the inner wall of the outer shell 10, and the collision between the mixing rods themselves and the fertilizer.
[0030] Furthermore, fixing plates 20 are movably connected to both the left and right ends of the connecting plate 9, and bolts are inserted inside the fixing plates 20. By bolting the fixing plates 20 to the connecting block 8, the connecting plate 9 can be fixed.
[0031] The usage method of this embodiment is as follows: First, manually rotate the connecting plate 9 and the outer shell 10 horizontally, and drive the connecting plate 9 and the outer shell 10 to slide down to the surface of the bottom plate 1 through the drive of the lead screw 6. At this time, open the end cover 19 and add lumpy fertilizer into the outer shell 10. Then, control the outer shell 10 and the connecting plate 9 to reset, and fix them by bolt connection between the fixing piece 20 and the connecting block 8. Then, the user starts the relevant motor and pushes the device to move. The motor drives the outer shell 10 and the first stirring rod 16 to rotate in opposite directions, so that the first stirring rod 16 and the second stirring rod 17 can achieve bidirectional crushing. When the outer shell 10 rotates, its single discharge port 11 will discharge material because it moves to the bottom opening of the connecting plate 9. During the discharge process, the fertilizer that is not crushed is blocked by the filter screen 12 and cannot be spilled out, while the other discharge ports 11 are blocked by the inner wall of the connecting plate 9. As the connecting plate 9 continues to rotate, the position of the discharge port 11 that was previously discharging material changes, and the lumpy fertilizer accumulated on its surface will fall due to gravity and be stirred and crushed again.
[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
