Description

Technical Field

[0001] This invention relates to the field of organic fertilizer application technology, and in particular to a vibrating grassland organic fertilizer granule screening and application device. Background Technology

[0002] In agricultural production, fertilization is a crucial step in ensuring crop growth. However, traditional fertilization methods have many problems.

[0003] On the one hand, fertilizers are prone to caking during storage or transportation due to moisture, compression, and other factors. Direct application of fertilized fertilizer clumps makes it difficult to disperse them evenly, leading to excessive localized application, soil burn, and negatively impacting crop growth. On the other hand, fertilizer often becomes clogged in application pipes and other parts of the fertilization device during transport due to particle adhesion, reducing efficiency and requiring tedious cleaning. Furthermore, traditional fertilization devices are ineffective at mixing and sieving fertilizer particles, making it difficult to ensure uniformity and potentially hindering balanced crop growth. Therefore, there is an urgent need for a fertilization device that can effectively solve fertilizer caking, prevent clogging of application pipes, and ensure uniform fertilization. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a vibrating grassland organic fertilizer granule screening and application device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibrating grassland organic fertilizer granule screening and application device includes a hopper fixedly connected to a fertilizer applicator, and further includes:

[0007] A screening cylinder is fixedly connected to a fertilizer application vehicle, and a cylinder cover is detachably connected to the top of the screening cylinder;

[0008] A drive rod is rotatably connected to the cylinder cover, and a first stirring blade is fixedly connected to the bottom of the drive rod;

[0009] A drive block is slidably connected to a drive rod. A connecting rod is fixedly connected to the side wall of the drive block. A hanging rod is fixedly connected to the connecting rod. A second stirring blade is fixedly connected to the bottom end of the hanging rod.

[0010] The screen is fixedly connected inside the screening cylinder;

[0011] An air supply pipe is rotatably connected to a screen. The air supply pipe is detachably connected to a drive rod. Multiple sets of air blowing pipes are fixedly connected to the bottom side wall of the air supply pipe, and the air blowing pipes are placed in the hopper.

[0012] Preferably, a corrugated plate is fixedly connected inside the screening cylinder, the connecting rod abuts against the upper surface of the corrugated plate, and a first drive motor is fixedly connected to the cylinder cover, the drive end of the first drive motor being fixedly connected to the drive rod.

[0013] Preferably, the drive rod has a sliding cavity and a pressure accumulating cavity, and a connecting pipe is fixedly connected to the drive rod. The sliding cavity is connected to the pressure accumulating cavity through the connecting pipe. When the gas supply pipe is connected to the drive rod, the gas supply pipe is connected to the pressure accumulating cavity.

[0014] Furthermore, a sliding plug is slidably connected in the sliding cavity, and a pressure rod is fixedly connected to the sliding plug. The end of the pressure rod away from the sliding plug is fixedly connected to the driving block.

[0015] Furthermore, a first spring is fixedly connected to the slide plug, and the end of the first spring away from the slide plug is fixedly connected to the top wall inside the slide cavity.

[0016] Furthermore, a second spring is fixedly connected to the drive block, and the end of the second spring away from the drive block is fixedly connected to the drive rod.

[0017] Preferably, the air blowing pipe is an elastic pipe, and multiple sets of unidirectional air blowing holes are fixedly connected to the side wall of the air blowing pipe.

[0018] Furthermore, an air supply pipe is fixedly connected to the drive rod, the air supply pipe is connected to the sliding cavity, and both the air supply pipe and the connecting pipe are equipped with a one-way valve.

[0019] Furthermore, a mesh is fixedly connected to the top of the air supply pipe.

[0020] Preferably, the top of the screening cylinder has an installation hole, a magnet is fixedly connected in the installation hole, and an installation rod is fixedly connected to the bottom of the cylinder cover. The installation rod matches the installation hole, and the installation rod is an iron rod that attracts the magnet.

[0021] Compared with the prior art, the present invention provides a vibrating grassland organic fertilizer granule screening and application device, which has the following beneficial effects:

[0022] 1. The present invention uses a first drive motor to drive a drive rod to rotate. The first stirring blade on the drive rod and the second stirring blade that slides up and down and rotates with the drive block work together to fully stir and beat the fertilizer in the screening cylinder. This can effectively break up the compacted fertilizer lumps, avoid local soil "burning" caused by the concentration of fertilizer lumps during fertilization, and ensure the normal growth of subsequent crops.

[0023] 2. The present invention uses air blown out through the air pipe to blow the fertilizer particles in the hopper, preventing the particles from sticking together and clumping. At the same time, it agitates the fertilizer, making it easier for the fertilizer to leak out through the fertilizer pipe. On the other hand, the second drive motor drives the feeding rod to rotate inside the fertilizer pipe, which accelerates the leakage speed of the fertilizer particles. The dual effect effectively prevents the fertilizer particles from clogging at the end of the fertilizer pipe and improves the fertilization efficiency.

[0024] 3. The cylinder cover in this invention is detachably connected by the attraction between the magnet and the iron rod, which makes it convenient to add fertilizer into the screening cylinder and clean the internal parts; the mesh at the top of the air supply pipe effectively prevents fertilizer particles from entering, ensuring the stability of air supply. The overall operation is simple and convenient for daily maintenance and use. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1: Refer to Figures 1-8 It includes a hopper 101 fixedly connected to the fertilizer applicator 1, and also includes:

[0036] Screening cylinder 2 is fixedly connected to fertilizer vehicle 1, and a cylinder cover 3 is detachably connected to the top of screening cylinder 2;

[0037] The drive rod 5 is rotatably connected to the cylinder cover 3, and the first stirring blade 504 is fixedly connected to the bottom of the drive rod 5;

[0038] The drive block 8 is slidably connected to the drive rod 5. A connecting rod 7 is fixedly connected to the side wall of the drive block 8. A hanging rod 701 is fixedly connected to the connecting rod 7. A second stirring blade 7011 is fixedly connected to the bottom end of the hanging rod 701.

[0039] Screen 9 is fixedly connected in screening cylinder 2;

[0040] The air supply pipe 6 is rotatably connected to the screen 9. The air supply pipe 6 is detachably connected to the drive rod 5. Multiple sets of air blowing pipes 601 are fixedly connected to the bottom side wall of the air supply pipe 6. The air blowing pipes 601 are placed in the hopper 101.

[0041] It should be noted that when the gas pipe 6 is connected to the bottom end of the drive rod 5, it is an interference fit to ensure that when the drive rod 5 rotates, it can drive the gas pipe 6 to rotate synchronously.

[0042] It should also be noted that the bottom of the hopper 101 is also fixedly connected with symmetrically arranged fertilizer pipes 1011, which are used to drop the fertilizer particles in the hopper 101 into the pre-dug fertilizer trough.

[0043] Reference Figure 1, Figure 4 A second drive motor 102 is fixedly connected to the fertilizer applicator 1. A feeding rod 1021 is fixedly connected to the drive end of the second drive motor 102. The end of the feeding rod 1021 away from the second drive motor 102 is placed in the fertilizer tube 1011. When the second drive motor 102 drives the feeding rod 1021 to rotate, it can accelerate the leakage of fertilizer particles in the fertilizer tube 1011 and prevent fertilizer particles from clogging the tail end of the fertilizer tube 1011.

[0044] A corrugated plate 202 is fixedly connected in the screening cylinder 2, and the connecting rod 7 abuts against the upper surface of the corrugated plate 202. A first drive motor 4 is fixedly connected to the cylinder cover 3, and the drive end of the first drive motor 4 is fixedly connected to the drive rod 5.

[0045] The drive rod 5 has a sliding cavity 501 and a pressure accumulator 503. A connecting pipe 502 is fixedly connected to the drive rod 5. The sliding cavity 501 is connected to the pressure accumulator 503 through the connecting pipe 502. When the gas supply pipe 6 is connected to the drive rod 5, the gas supply pipe 6 is connected to the pressure accumulator 503.

[0046] A sliding plug 5012 is slidably connected in the sliding cavity 501, and a pressure rod 5013 is fixedly connected to the sliding plug 5012. The end of the pressure rod 5013 away from the sliding plug 5012 is fixedly connected to the drive block 8.

[0047] Reference Figures 1-8 In actual use, the staff opens the cylinder cover 3 and pours the fertilizer granules to be fertilized into the screening cylinder 2; after adding, the cylinder cover 3 is closed again, and the first drive motor 4 on the cylinder cover 3 is started. The drive end of the first drive motor 4 drives the drive rod 5 to rotate.

[0048] Simultaneously, the staff pushes the fertilizer applicator 1 to the pre-dug fertilizer trough. The first stirring blade 504 rotates with the drive rod 5, initially stirring the fertilizer in the screening cylinder 2. The drive block 8 on the drive rod 5 rotates with the drive rod 5, and the connecting rod 7 on the side wall of the drive block 8 continuously abuts against the upper surface of the corrugated plate 202 in the screening cylinder 2. Under the cooperation of the undulating contour of the corrugated plate 202, the restoring force of the second spring 801, and the damping rod 802, the drive block 8 slides up and down along the drive rod 5, driving the connecting rod 7 to move up and down synchronously. The hanging rod 701 on the connecting rod 7 and the second stirring blade 7011 at the bottom move up and down with the connecting rod 7 and rotate, fully stirring the fertilizer. At the same time, it cooperates with the screen 9 in the screening cylinder 2 to complete the screening. Fertilizer particles that meet the particle size requirements pass through the screen 9 and fall into the hopper 101 below.

[0049] The fertilizer granules in the screening cylinder 2 are stirred by two sets of stirring blades, which can effectively break up any granular fertilizer clumps that may clump together, thus ensuring that the soil will not be burned due to excessive fertilization during subsequent fertilization.

[0050] During the rotation of the drive rod 5, the drive block 8 slides up and down, driving the pressure rod 5013 to push the slide plug 5012 to slide back and forth in the slide cavity 501. The slide cavity 501 is connected to the pressure accumulator 503 through the connecting pipe 502, so that the pressure accumulator 503 gradually accumulates pressure. When the electromagnetic pressure valve on the gas supply pipe 6 reaches the set threshold, the gas in the pressure accumulator 503 is transported to the blowing pipe 601 through the gas supply pipe 6 and blown out from the one-way blowing hole 6011 on the side wall of the blowing pipe 601. This facilitates the fertilizer to leak out from the fertilizer pipe 1011 at the bottom of the hopper 101, and the fertilizer particles fall smoothly into the pre-dug fertilizer trough.

[0051] After fertilization, first turn off the first drive motor 4 and the second drive motor 102; then open the cylinder cover 3 and clean the screening cylinder 2, the hopper 101, and the fertilizer pipe 1011 to prepare for the next use.

[0052] A first spring 5014 is fixedly connected to the slide plug 5012, and the end of the first spring 5014 away from the slide plug 5012 is fixedly connected to the top wall of the inner cavity 501.

[0053] Reference Figure 5 The first spring 5014 provided on the slider 5012 enables the slider 5012 to be quickly reset.

[0054] A second spring 801 is fixedly connected to the drive block 8, and the end of the second spring 801 away from the drive block 8 is fixedly connected to the drive rod 5.

[0055] By means of the second spring 801 provided on the drive block 8, when the connecting rod 7 slides from the high end to the low end of the wave plate 202, the second spring 801 can reset the drive block 8, thereby allowing the connecting rod 7 to remain in contact with the wave plate 202.

[0056] In practical implementation, a damping rod 802 is fixedly connected to the drive block 8, and the drive end of the damping rod 802 is connected to the drive rod 5.

[0057] Reference Figure 4 , Figure 6 and Figure 8 The air blowing pipe 601 is an elastic pipe, and multiple sets of one-way air blowing holes 6011 are fixedly connected to the side wall of the air blowing pipe 601.

[0058] In practice, the gas pipeline 6 is equipped with a commercially available electromagnetic pressure valve.

[0059] When the air blowing pipe 601 rotates, the pressure in the accumulator 503 reaches the threshold set by the pressure valve, and the pressure valve opens. At this time, the gas in the accumulator 503 will be transported through the air supply pipe 6 and finally blown out through the one-way air blowing hole 6011 on the air blowing pipe 601. The blown gas can effectively blow the fertilizer particles to prevent the particles from sticking together and clumping again. On the other hand, by blowing the fertilizer particles in the hopper 101, the fertilizer can be turned over, which makes it easier for the fertilizer to leak out through the fertilizer application pipe 1011 at the bottom of the hopper 101.

[0060] Meanwhile, by setting the air blowing pipe 601 as an elastic tube, when the air blowing pipe 601 rotates, due to the rotational resistance of the material in the hopper 101, the air blowing pipe 601 will undergo a certain deformation, and after the rotational resistance disappears, it will quickly spring back to its original position. At this time, the air blowing pipe 601 will swing irregularly, which can then perform irregular impact and airflow impact on the fertilizer in the hopper 101, further improving the agitation effect on the fertilizer particles.

[0061] An air supply pipe 5011 is fixedly connected to the drive rod 5. The air supply pipe 5011 is connected to the slide cavity 501, and a one-way valve is provided on both the air supply pipe 5011 and the connecting pipe 502.

[0062] Reference Figure 8 In practice, a mesh is fixedly connected to the top of the air supply pipe 5011.

[0063] By fixing a mesh to the top of the air supply pipe 5011, it is possible to effectively prevent fertilizer particles inside the cylinder from falling into the air supply pipe 5011, thereby ensuring that the air supply pipe 5011 can stably supply air to the sliding cavity 501.

[0064] The top of the screening cylinder 2 has an installation hole 201, and a magnet 2011 is fixedly connected in the installation hole 201. The bottom of the cylinder cover 3 is fixedly connected to an installation rod 301. The installation rod 301 matches the installation hole 201, and the installation rod 301 is an iron rod. The installation rod 301 is attracted to the magnet 2011.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
