Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery technical field especially relates to rice seed anti -rice blast inoculant uniform atomization coating machine. BACKGROUND

[0002] Rice blast is an important disease affecting rice production, traditionally often through spraying chemical fungicides for prevention and control. However, this way brings environmental pollution, pesticide residues and drug resistance of pathogenic bacteria and other problems. As an alternative, anti-rice blast inoculant (usually containing bacillus subtilis and other beneficial live bacteria) emerged as the times require. Inoculant by covering in the outer layer of rice seeds, can establish a micro-ecological protective layer for seeds, so as to realize the effective prevention and control of rice blast.

[0003] The lotus root type coating machine is an atomization coating equipment widely used in seed treatment in agriculture, and its main structure usually includes a motor-driven inclined rotating coating disc, a spraying system for atomizing and spraying liquid medicine, a drying system for blowing the surface of wet seeds after spraying, and a dust removal machine for dust removal. Its working principle is: after the seeds enter the motor-driven inclined rotating coating disc, they are driven by the transmission mechanism to produce continuous and upward rolling movement through centrifugal force and friction. In this process, the spraying system atomizes the coating agent (such as anti-rice blast inoculant) into uniform droplets and sprays it on the rolling seeds. Through the continuous mixing and friction between the seeds, the liquid medicine rapidly spreads on the seed surface and forms a uniform film. The coated seeds are blown dry by the drying system, and the dust removal machine continuously removes the lint and dust generated during the process through the dust suction hood to keep the working environment clean.

[0004] However, the traditional lotus root type coating machine still has the following defects in actual application:

[0005] The lotus root type coating machine relies on the passive rolling of the seeds on the fixed disc wall. When treating smooth rice seeds or using inoculant with certain viscosity, the seed layer is prone to form overall sliding instead of sufficient rolling, resulting in insufficient contact between the seeds and the inoculant and uneven coating quality.

[0006] The nozzle position of the traditional spraying system is fixed, which can only cover part of the seed bed area, resulting in over-spraying of some seeds, while the seeds at the edge or center of the movement are not sprayed enough, thereby affecting the overall coating effect.

[0007] The lint and dust generated during the coating process easily block the filter screen in the dust removal pipeline. Once the filter screen is blocked, the pipeline suction force will decrease, causing dust overflow and polluting the working environment. Moreover, the operator needs to frequently stop the machine for maintenance, which seriously affects the continuity of production. Therefore, the rice seed anti-rice blast inoculant uniform atomization coating machine is proposed to solve the above problems. UTILITY MODEL CONTENTS

A self-cleaning filtering mechanism 9 is arranged inside the dust suction pipe 8.

[0056] The peristaltic mixing mechanism 5 comprises a supporting outer disc 501, which is fixedly connected to the end of the connecting piece 4. A cladding disc 502 is rotatably connected inside the supporting outer disc 501. A flexible inner liner 503 is installed inside the cladding disc 502. Cam blocks 504 are arranged inside the supporting outer disc 501. A sliding rod 505 is slidably connected to the middle part of the cladding disc 502. A roller 506 is rotatably connected to the end of the sliding rod 505 away from the flexible inner liner 503. A push plate 507 is fixedly connected to the end of the sliding rod 505 close to the flexible inner liner 503. The roller 506 is in contact with the cam blocks 504. The push plate 507 is in contact with the outer wall of the flexible inner liner 503.

[0057] Specifically, the cladding disc 502 is driven to rotate by the driving power source (such as a main motor and a speed reducer) of the coating mixing machine. When the cladding disc 502 rotates, the supporting outer disc 501 does not rotate. The cam blocks 504 can be uniformly arranged inside the supporting outer disc 501. A plurality of guide holes are formed in the cladding disc 502 and distributed along the radial direction of the cladding disc 502. The sliding rod 505 passes through the guide holes, so that it can reciprocate along the radial direction.

[0058] Please refer to the drawings Figure 1 - the drawings Figure 6In an optimal embodiment of the present application, the outer side of the cam block 504 is fixedly connected with a mounting block 508, the inner wall of the supporting outer disc 501 is provided with a mounting groove 509, the mounting block 508 is arranged inside the mounting groove 509, the cam block 504 and the supporting outer disc 501 form a wave-shaped track, the roller 506 is slidingly connected in the wave-shaped track, and the supporting outer disc 501 can be detachably divided into two parts and is fixedly connected by screws and nuts.

[0059] Specifically, the main power source of the coating mixing machine drives the coating disc 502 to rotate, the rollers 506 at the ends of the plurality of slide rods 505 rotating together with the coating disc 502 roll along the contours of the fixed supporting outer disc 501 and the cam block 504, when the rollers 506 move to the peak position of the cam block 504, the cam block 504 pushes the rollers 506 to make the slide rods 505 slide radially towards the center, thereby driving the push plate 507 to lift the contacted flexible inner liner 503 to make the flexible inner liner 503 bulge towards the center of the disc body, and when the rollers 506 move to the valley position, the slide rods 505 retract outwardly.

[0060] The wave-shaped track is spliced by a plurality of independently detachable cam blocks 504, by replacing the cam blocks 504 with different heights, slopes or curve contours, the contour of the entire wave-shaped track can be changed, the amplitude, frequency and shape of the wave can be adjusted, and the mixing process requirements of rice seed materials with different physical properties can be adapted. After the supporting outer disc 501 is disassembled, the mounting block 508 of the cam block 504 is taken out of the mounting groove 509, and different cam blocks 504 can be disassembled and replaced.

[0061] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 6 In an optimal embodiment of the present application, the flexible inner liner 503 is detachably installed in the inside of the coating disc 502 by the bolt 510, and the flexible inner liner 503 contacts the rice seeds.

[0062] Specifically, the flexible inner liner 503 is made of an elastomer material (such as silicone rubber or polyurethane), and the surface of the flexible inner liner 503 is a mixing working surface directly contacting the rice seed materials. In order to facilitate maintenance and replacement, the flexible inner liner 503 is detachably installed in the inside of the coating disc 502 by the bolt 510.

[0063] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 7 , the accompanying drawings Figure 8 and the accompanying drawings Figure 9In an optimal embodiment of the utility model, the compound motion spray mechanism 7 includes fixed frame 701, fixed frame 701 is fixedly connected at the installation end of support frame 6, the inside installation of fixed frame 701 has motor 702, the output of motor 702 is fixedly connected with swing frame 703, the connecting end of swing frame 703 is rotatably connected with moving block 704, the side of moving block 704 away from swing frame 703 is fixedly connected with arc connecting frame 705, the inside installation of arc connecting frame 705 has atomizing nozzle 706, the inside of fixed frame 701 is provided with guide frame 707, moving block 704 is slidably connected at the middle part of guide frame 707.

[0064] The outside of moving block 704 is fixedly connected with sliding block 709, the inside of guide frame 707 is provided with sliding slot 710, and sliding block 709 is slidably connected in the inside of sliding slot 710.

[0066] Specifically, after motor 702 starts, swing frame 703 is driven to rotate circumferentially, and the rotating movement of swing frame 703 is transmitted to moving block 704. Due to the cooperation of sliding block 709 and sliding slot 710 and the cooperation of positioning column 711 and positioning groove 712, moving block 704 must first slide in the sliding slot 710 of guide frame 707, and secondly, guide frame 707 where moving block 704 is located must swing horizontally around positioning column 711. Therefore, arc connecting frame 705 and atomizing nozzle 706 fixed on moving block 704 will keep a three-dimensional, reciprocating hemispherical motion trajectory, and the hemispherical motion trajectory is formed by superimposing the vertical lifting movement and the horizontal arc swing movement. The hemispherical compound motion trajectory enables atomizing nozzle 706 to scan the material bed rolling in the mixing mechanism and improves the coating coverage area.

[0067] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 10 , the accompanying drawings Figure 11 and the accompanying drawings Figure 12 In an optimal embodiment of the utility model, the self-cleaning filter mechanism 9 includes filter screen 901, filter screen 901 is arranged in the inside of dust suction pipe 8, rotating shaft 902 is rotatably connected at the middle part of filter screen 901, propeller 903 is fixedly connected at one end of rotating shaft 902 close to the dust suction side of dust suction pipe 8, connecting shell 904 is fixedly connected on the outside of rotating shaft 902, cleaning brush 905 is arranged in the middle part of connecting shell 904 through elastic component, and the brush of cleaning brush 905 is in contact with filter screen 901.

[0068] Specifically, when the dust collector 3 works, the suction airflow generated in the dust suction pipe 8 blows the propeller 903 to rotate, the rotating propeller 903 drives the connecting shell 904 and the cleaning brush 905 on the connecting shell 904 to rotate synchronously through the rotating shaft 902, so that the bristles of the cleaning brush 905 continuously sweep the windward surface of the filter screen 901, and the dust particles that try to adhere or have adhered to the filter screen 901 are removed, thereby realizing online automatic cleaning of the filter screen 901.

[0069] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 10 , the accompanying drawings Figure 11 and the accompanying drawings Figure 12 , in an preferred embodiment of the present application, the elastic assembly comprises a mounting frame 906, the mounting frame 906 is fixedly connected to the middle part of the connecting shell 904, the outer side of the mounting frame 906 is slidably connected with a sliding block 907, the side surface of the sliding block 907 is rotatably connected with a connecting rod 908, the connecting end of the connecting rod 908 is rotatably connected with the cleaning brush 905, and the outer periphery of the mounting frame 906 is sleeved with a spring 909.

[0070] Specifically, one end of the spring 909 abuts against the root of the mounting frame 906, and the other end abuts against the sliding block 907, so as to apply a continuous elastic pushing force to the sliding block 907, the elastic pushing force is transmitted to the cleaning brush 905 through the connecting rod 908, so that the cleaning brush 905 is pressed towards the filter screen 901, and meanwhile the elastic assembly allows the cleaning brush 905 to float within a certain range, so as to compensate for the wear of the bristles or the unevenness of the surface of the filter screen 901, and the telescopic rod 910 keeps the moving track of the cleaning brush 905 during the movement of the cleaning brush 905.

[0071] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 12 In an preferred embodiment of the present application, the top of the mixing machine shell 1 is provided with a drying pipe 10, the top of the carrying vehicle 2 is provided with a vaccine storage barrel 11 and a medicine supply control machine 12, and the side surface of the atomizing nozzle 706 is provided with a liquid infusion pipe connecting port 708.

[0072] Specifically, the top of the mixing machine shell 1 is provided with the drying pipe 10 for preliminarily drying the coated material, the top of the carrying vehicle 2 is further provided with the vaccine storage barrel 11 for storing the vaccine and the medicine supply control machine 12 for controlling the supply of the vaccine, and the vaccine storage barrel 11, the medicine supply control machine 12 and the liquid infusion pipe connecting port 708 are sequentially connected through a liquid infusion pipe, thereby forming a supply and atomization path of the vaccine.

[0073] Working principle: in the mixing stage, the peristaltic mixing mechanism 5 is started, the driving power source of the coating mixer drives the rotation of the coating disc 502, and a plurality of slide rods 505 rotate with the coating disc 502, the end roller 506 of the slide rod 505 rolls along the contour of the cam block 504 on the inner wall of the fixed support outer disc 501. When the roller 506 moves to the peak position of the cam block 504, the slide rod 505 is pushed to the center of the coating disc 502, and the push plate 507 at the other end pushes up the local area of the flexible inner liner 503. The continuous rotation of the coating disc 502 forms a continuous, circumferential wave motion on the flexible inner liner 503, which can actively loosen and push the rice on the surface of the flexible inner liner 503, destroy the overall sliding trend of the rice, and eliminate the mixing dead angle in the center, thereby realizing the active and uniform mixing of the materials.

[0074] In the spraying stage, the composite motion spraying mechanism 7 is started, the motor 702 drives the swing frame 703 to rotate, the swing frame 703 drives the moving block 704 to move through rotation, and since the moving block 704 is simultaneously constrained in the sliding groove 710 of the guide frame 707 to move vertically up and down, and the guide frame 707 itself swings horizontally in the fixed frame 701 through the positioning column 711, the simultaneous vertical up-and-down movement and horizontal swinging make the arc-shaped connecting frame 705 and the atomizing nozzle 706 fixed on the moving block 704 generate a three-dimensional, reciprocating hemispherical motion trajectory, so that the inoculant can be sprayed in a wide range and at multiple angles to the materials rolling in the mixing mechanism, effectively improving the uniformity of atomization coating.

[0075] When the dust removal machine 3 is working, the high-speed suction airflow generated in the dust suction pipe 8 impacts and drives the propeller 903 arranged on the upstream side of the airflow to rotate, the propeller 903 drives the connecting shell 904 and the cleaning brush 905 arranged on the downstream side of the airflow to rotate synchronously through the rotating shaft 902, and the elastic assembly always applies an elastic pushing force to the cleaning brush 905, which is directed to the filter screen 901, so that the brush is tightly attached to the windward surface of the filter screen 901. The rotating cleaning brush 905 continuously mechanically brushes the surface of the filter screen 901 to remove the attached dust particles, effectively preventing the filter screen from being blocked and prolonging the maintenance cycle.
