Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer spreaders, in particular to an organic fertilizer spreading mechanism. Background Art

[0002] Organic fertilizers, also known as "farmyard manure," are any fertilizers made from organic matter (compounds containing carbon). These include human waste, manure, compost, green manure, cake fertilizer, and biogas fertilizer. They are diverse, widely available, and have a long-lasting effect. Most of the nutrients in organic fertilizers are in an organic state, making them difficult for crops to directly utilize. Microorganisms slowly release these nutrients, providing a continuous supply of nutrients to crops. Applying organic fertilizers improves soil structure, balances water, fertilizer, air, and heat in the soil, and enhances soil fertility and productivity.

[0003] Organic fertilizer is different from general chemical fertilizer. It contains less nitrogen, phosphorus and potassium. Therefore, the amount of fertilizer applied is higher than that of general chemical fertilizer. The efficiency of manual fertilization is low. There is also equipment that can be used to spread organic fertilizer, but in actual use, due to the relatively high water content of some organic fertilizers, it is not smoothly transferred in the fertilizer hopper, and blockage may occur at the fertilizer outlet, which requires manual processing and affects continuous fertilization operations. Utility Model Content

[0006] The top of the fertilizer hopper is provided with a feed port for the entry of fertilizer, and the sides of the two ends of the bottom of the fertilizer hopper in the longitudinal direction are respectively provided with discharge ports for the discharge of fertilizer. A spiral rod is connected to the bottom of the inner cavity of the fertilizer hopper and rotates along its length. The spiral rod is provided with two spiral blades with opposite spiral directions. The outer diameter of the spiral blades is adapted to the width of the bottom of the inner cavity of the fertilizer hopper, and the ends of the spiral blades extend to the position corresponding to the discharge port.

[0039] In order to more clearly describe the specific structural composition of the organic fertilizer fertilization mechanism, Figure 1-8 Describe this embodiment:

[0040] like Figure 1 、 Figure 2 and Figure 3As shown, an organic fertilizer applying mechanism includes a fertilizer hopper 1, the top of the fertilizer hopper 1 is provided with a feeding port for fertilizer to enter, and the side surfaces at both ends in the length direction of the bottom of the fertilizer hopper 1 are respectively provided with discharge ports 101 for fertilizer to be spilled, and a spiral rod 2 is rotatably connected to the bottom of the inner cavity of the fertilizer hopper 1 along its length direction, and two spiral blades 201 with opposite spiral directions are relatively provided on the spiral rod 2, the outer diameter of the spiral blade 201 is adapted to the width of the bottom of the inner cavity of the fertilizer hopper 1, and the end of the spiral blade 201 extends to a position corresponding to the discharge port 101; a bearing seat 3 corresponding to the discharge port 101 is fixed to the outer wall of the fertilizer hopper 1, and a paddle wheel 4 is rotatably connected to the bearing seat 3, and the paddle wheel 4 has a paddle 401 that can rotate into the discharge port 101; the outer wall of the fertilizer hopper 1 is provided with a driving mechanism for driving the spiral rod 2 and the paddle wheel 4 to rotate respectively.

[0041] Organic fertilizer is added into the fertilizer hopper 1 from the feed port. During the fertilizing process, the spiral rod 2 and the spiral blade 201 rotate, and the organic fertilizer in the middle section of the bottom of the fertilizer hopper 1 is transferred to the discharge ports 101 on both sides under the drive of the spiral blade 201. The paddle wheel 4 rotates, and the paddle 401 on it rotates from the outside of the fertilizer hopper 1 into the discharge port 101. The fertilizer is pulled out by the rotation of its end and spread on the soil layer.

[0042] In order to increase the capacity of the fertilizer hopper 1 and adapt to the outer diameter of the spiral blade 201, the cross-sectional shape of the fertilizer hopper 1 can be designed to be conical, that is, the width of the fertilizer hopper narrows from the top to the bottom.

[0043] See Figure 2 and Figure 4 In the above embodiment, the paddle wheel 4 includes a paddle 401, a material shaft 402 and an end plate 403. Both ends of the material shaft 402 are rotatably connected to the bearing seat 3. The middle part of the material shaft 402 is fixed with a paddle 401 along its circumference. The end plates 403 are fixed to both ends of the material shaft 402. The end plates 403 are in contact with the corresponding sides of the paddle 401. The function of the end plates 403 is to reduce the diffusion of organic fertilizer in the axial direction of the paddle wheel 4; in order to further improve the anti-slip ability of the paddle when it contacts the organic fertilizer and ensure the effect of scraping out the fertilizer, a rake tooth 404 is fixed on the material-facing side of the paddle 401, which rotates into the discharge port 101. When the rake tooth 404 contacts the organic fertilizer, it is easier to bring it out.

[0044] The driving mechanism includes a first driving mechanism capable of driving the screw rod 2 to rotate forward or reverse, and a second driving mechanism capable of driving the paddle wheel 4 to rotate;

[0045] The first driving mechanism is a conventional configuration and may include a first motor and a transmission mechanism (belt or chain). The first motor directly drives the screw rod 2 to rotate through the transmission mechanism; the screw rod 2 and the spiral blade 201 can rotate forward or reversely under the drive of the first motor. When the organic fertilizer is not discharged smoothly, the spiral blade 201 can be controlled to rotate in the reverse direction as appropriate. The forward rotation transfers the organic fertilizer to the discharge port 101. The appropriate reverse rotation can adjust the distribution of the organic fertilizer in the fertilizer hopper 1, which is conducive to pushing the organic fertilizer out when the forward rotation is resumed.

[0046] See Figure 5 The second drive mechanism includes a drive motor 10 and a mounting base 11 fixed to the outer wall of the fertilizer hopper 1. A driving shaft 12 is rotatably arranged in the axial hole of the mounting base 11. Bevel gears 13 are respectively fixed to the middle of the driving shaft 12 and the output shaft of the drive motor 10. The two bevel gears 13 are meshed. Sprockets 14 are respectively provided at the ends of the driving shaft 12 and the ends of the paddle wheel 4. The corresponding sprockets 14 are connected by a chain 15. The second drive mechanism enables the two paddle wheels 4 to be independently arranged while rotating synchronously. The independent paddle wheels 4 ensure that the paddles 401 thereon can rotate into the discharge port 101. During the fertilization process, the drive motor 10 drives the driving shaft 12 to rotate through the two bevel gears 13. The driving shaft 12 drives the material shaft 402 and the paddle wheel 4 to rotate through the sprocket 14 and the chain 15.

[0047] See Figure 5 、 Figure 6 and Figure 7 The fertilizer hopper 1 is installed on a traction device (agricultural machinery that can be mounted, such as a tractor) for use. It can be raised and lowered relative to the traction device, and is easy to install and disassemble. A fixed frame 5 is fixed to the outer wall of the fertilizer hopper 1. A movable frame 6 is provided inside the fixed frame 5, which can slide vertically relative to it and is used to connect to the external traction device. The fixed frame 5 and the movable frame 6 are connected by a hydraulic cylinder 7. After the movable frame 6 is fixed to the traction device, the fixed frame 5 and the fertilizer hopper 1 are raised by the hydraulic cylinder 7. During the fertilization operation, the fertilizer hopper 1 can maintain a certain height with the soil layer.

[0048] Specifically, the fixing frame 5 includes two vertical guide rails 501 and a cross bar 502 connecting the two vertical guide rails 501 . The lower end of the hydraulic cylinder 7 is fixed on the cross bar 502 . The two vertical guide rails 501 are detachably connected to the fertilizer hopper 1 through a connector 503 .

[0049] Specifically, the movable frame 6 includes a sliding portion 601, a mounting portion 602 protruding outward is fixed to the rear side of the sliding portion 601, and pulleys 603 that cooperate with the track grooves of the vertical guide rails 501 are provided on both sides of the sliding portion 601. The mounting portion 602 is used to connect the traction equipment. The sliding portion 601 can be installed between the two vertical guide rails 501. The upper end of the hydraulic cylinder 7 is fixedly connected to the sliding portion 601. When the sliding portion 601 moves along the vertical guide rails 501, the pulleys 603 slide in the track grooves of the vertical guide rails 501.

[0050] In order to ensure safety and stability, a baffle 8 is fixed on the rear side of the sliding part 601, and a limit plate 9 is fixed on the fixed frame 5 (the limit plate 9 is detachable and can be connected by bolts). The limit plate 9 is located between the baffle 8 and the mounting part 602. The movable frame 6 is constrained by the limit plate 9 when lifting and lowering, and cannot be completely separated from the fixed frame 5 in the working state. When disassembled in the non-working state, the limit plate 9 needs to be removed first.

[0051] Parts not described in detail in the above embodiments are prior art.

[0052] It should be noted that although the present invention has been described through the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and modifications to the present invention, and such changes and modifications shall fall within the scope of protection of the appended claims and their equivalents.
