Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of coating, in particular to a wheat biological agent coating device. BACKGROUND

[0002] The biological agent is a live bacteria preparation processed by fermentation broth of target microorganisms (effective bacteria) adsorbed by adsorbents after industrialized production and expansion. It is widely used in wheat planting and can effectively improve the growth environment of wheat, promote the growth and development of wheat, and improve the yield and quality.

[0003] Coating processing of the wheat biological agent can avoid local high concentration to harm plants, and can also delay nutrient release for continuous absorption by plants.

[0004] The traditional coating method for the wheat biological agent is pot coating and fluidized bed coating.

[0005] The pot coating method is to put the material into a tilted rotating coating pot, and the material is rolled by rotating the pot body, while the coating liquid is sprayed from the top or side, and the hot air is dried to form a uniform coating. Its equipment is simple, the cost is low, it is only suitable for small batch production, and the rolling uniformity of the material is poor, the coating time is long, and the coating efficiency is low.

[0006] The fluidized bed coating method is to make the material in the fluidized bed in a "boiling" state (fluidization) by the hot air at the bottom, and the coating liquid is atomized from the nozzle and sprayed to the surface of the material, and the hot air is dried synchronously to form a dense film. Its material is dispersed uniformly, and the thickness of the coating film is uniform; but the particle size of the material is required (fine powder flying or coarse particle settling should be avoided), the equipment cost is high, and continuous high-efficiency operation is not available. SUMMARY

[0007] In order to solve the problems that the traditional method cannot perform continuous coating operation on the wheat biological agent, the operation is complicated, and the coating efficiency is low, the application provides a wheat biological agent coating device.

[0008] The application is realized by the following technical scheme: A wheat biological agent coating device, comprising a base, a feeding bin and a vertical pipe fixedly installed on the base, further comprising a coating shell fixedly connected to the outer side of the vertical pipe and arranged in multiple spiral coils, a material channel in multiple spiral coils is formed in the coating shell, and the coating shell comprises a bottom shell in multiple spiral coils and an upper cover fixedly installed on the upper side of the bottom shell; a plurality of spray heads capable of spraying coating liquid into the material channel are installed on the upper cover at intervals along the spiral direction thereof, and a plurality of vibration motors are installed at intervals along the spiral direction of the bottom of the bottom shell; the feeding bin is fixedly connected to the upper end of the vertical pipe, and the feeding bin is communicated with the upper end of the material channel through the feeding pipe at the bottom; and a material containing box corresponding to the outlet at the lower end of the material channel is placed on the base.

[0009] The material passage section is rectangular.

[0010] The lower end of the feeding pipe is connected with a control valve, and the lower end of the control valve is communicated with the upper end of the material passage through a flexible connecting pipe.

[0011] The control valve comprises a connecting frame connected between the connecting pipe and the feeding pipe, and a plug plate is adjustably inserted on one side of the connecting frame.

[0012] The upper end of the material passage is connected with an air exhaust device.

[0013] An electric heating device is installed in the lower part of the material passage.

[0014] The air exhaust device comprises an ejector and an upper blocking cover blocking the upper end of the material passage, the ejector is fixedly connected with the upper blocking cover and communicated with the upper end of the material passage, and the high-pressure fluid end of the ejector is connected with a high-pressure gas pipe.

[0015] A plurality of bottom shell support rods are arranged on the side wall of the vertical pipe and fixedly connected with the bottom shell.

[0016] The inlet end of the spray head is connected with a coating liquid branch pipe penetrating through the side wall of the vertical pipe, and a coating liquid main pipe is arranged in the vertical pipe and communicated with the plurality of coating liquid branch pipes.

[0017] A support disc is rotatably arranged on the upper side of the base, and the material containers are arranged in a ring shape on the support disc.

[0018] The above technical solutions show that the present application has the following advantages: In use, the wheat bio-inoculant granules to be coated are poured into the feeding hopper and continuously conveyed to the upper end of the material channel through the feeding pipe. Under the action of gravity, the wheat bio-inoculant granules roll downwards along the multi-spiral material channel. Multiple vibrating motors vibrate the bottom shell, causing the wheat bio-inoculant granules (detached from the ground inside the bottom shell) to be thrown up (this also achieves aerial dispersion of the wheat bio-inoculant granules). Multiple nozzles spray coating liquid onto the thrown and dispersed wheat bio-inoculant granules (various coating liquids can be arranged according to the falling path) to achieve uniform coating liquid adhesion and improve the coating effect. After multiple throwing and coating operations, the wheat bio-inoculant granules finally fall into the bottom collection box through the lower end of the material channel. This wheat bio-inoculant coating device allows the wheat bio-inoculant granules to flow continuously within the material channel, enabling continuous and uninterrupted coating operations, effectively improving coating efficiency and quality. Furthermore, the overall structure is simple, compact, easy to operate, and highly practical. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figures 1-5 As shown, this invention discloses a wheat bio-inoculant coating device, comprising a circular base 1, a feeding hopper 2, a vertically fixed pipe 12 at the center of the base 1, and a coating shell 3 fixedly connected to the outside of the vertical pipe 12 and arranged in a multi-turn spiral (the central axis coincides with the axis of the vertical pipe 12, i.e., the distance between the multi-turn spirally arranged coating shell 3 and the center of the vertical pipe 12 at corresponding positions is equal). A multi-turn spiral material channel is formed inside the coating shell 3 (with an inclination angle of 2-5 degrees to ensure that the wheat bio-inoculant particles roll slowly within the material channel). The coating shell 3 includes a multi-turn spiral bottom shell 31 and a sealing fastener installed on the bottom shell 31. 1. The upper cover 32 on the upper side; several nozzles 4 capable of spraying coating liquid into the material channel are fixedly installed on the upper cover 32 at intervals along its spiral direction (the nozzles 4 are fixedly installed on the upper cover 32 from top to bottom); several vibration motors 5 are fixedly installed on the bottom of the bottom shell 31 at intervals along its spiral direction, and the vibration motors 5 are fixedly connected to the bottom of the bottom shell 31 through vibration motor connecting seats 51; the discharge bin 2 is fixedly connected to the upper end of the riser 12 through several discharge bin positioning sleeves 21, and the discharge bin 2 is connected to the upper end of the material channel through the discharge pipe 22 at its bottom; a material holding box 6 corresponding to the lower end outlet of the material channel is placed on the base 1.

[0028] In use, the wheat bio-inoculant granules to be coated are poured into the feeding hopper 2 and continuously conveyed to the upper end of the material channel through the feeding pipe 22. Under the action of gravity, the wheat bio-inoculant granules roll downwards along the multi-spiral material channel. Multiple vibrating motors 5 vibrate the bottom shell 31, causing the wheat bio-inoculant granules (which detach from the ground inside the bottom shell 31) to be thrown up (this can also achieve aerial dispersion of the wheat bio-inoculant granules). Coating liquid is sprayed onto the thrown and dispersed wheat bio-inoculant granules through multiple nozzles 4 (various coating liquids can be arranged according to the falling path) to achieve uniform coating liquid adhesion and improve the coating effect. After multiple throwing and coating operations, the wheat bio-inoculant granules finally fall into the bottom collection box 6 through the lower end of the material channel. This wheat bio-inoculant coating device allows the wheat bio-inoculant granules to flow continuously in the material channel, enabling continuous and uninterrupted coating operations, effectively improving coating efficiency and quality; moreover, the overall structure is simple, compact, easy to operate, and practical.

[0029] The base 1 has several evenly spaced, ring-shaped support legs 11 at its bottom, which can effectively provide stable support for the entire structure.

[0030] The riser 12 has several bottom shell support rods 35 (horizontally radial) spaced at intervals on its side wall. The upper outer end of each bottom shell support rod 35 is provided with a bottom shell support seat 34 that is connected to the bottom of the coating shell 3. The coating shell 3 is supported and fixedly connected to the side wall of the riser 12 by the multiple bottom shell support rods 35, ensuring the reliable stability of the installation of the coating shell 3, and the structure is compact and reasonably arranged.

[0031] In a further embodiment, the nozzle 4 and the vibration motor 5 are arranged in a one-to-one correspondence, and the vibration motor 5 is located at the upper position of the corresponding spiral line position. That is, the wheat biological agent particles are first vibrated and thrown up by the vibration motor 5 (with a downward parabolic trajectory in the material channel), and then the nozzle 4 sprays coating liquid onto the thrown wheat biological agent particles to improve the efficiency and uniformity of coating liquid adhesion of the wheat biological agent particles.

[0032] In a further embodiment, the material channel has a rectangular cross-section, i.e., the bottom shell 31 has a U-shaped cross-section. The upper cover 32 has flanges (facing downwards) on both sides that engage with the bottom shell 31. Sealing gaskets are provided on the upper edges of both sides of the bottom shell 31. The upper cover 32 and the bottom shell 31 can be locked together by quick-release locking handles. This allows the wheat bio-inoculant particles to disperse and roll within the bottom shell 31, preventing particle aggregation and improving coating uniformity. Furthermore, the upper cover 32 and the bottom shell 31 are detachably and sealed, preventing dust and coating liquid from overflowing and affecting the external environment. The upper cover 32 is also easy to separate, enabling convenient cleaning and maintenance of the material channel.

[0033] Furthermore, the bottom shell 31 is made of stainless steel with a smooth surface, ensuring that the material particles roll downwards and are easy to clean; the top cover 32 is made of transparent PVC material, which allows for a direct observation of the internal working status, making it easy to identify and address any problems promptly.

[0034] Furthermore, the bottom of the nozzle 4 is a long rectangular shape, and its distribution direction is consistent with the width direction of the material channel cross-section, ensuring that the spraying range of the nozzle 4 can completely cover the cross-section of the material channel and ensuring sufficient adhesion of the coating liquid to the wheat biological agent particles.

[0035] In addition, similar to the arrangement of the above-mentioned nozzle 4, the length direction of the vibration motor connecting seat 51 (rectangular) is consistent with the width direction of the material channel cross section, and the vibration motor 5 is installed at its bottom along the direction of the vibration motor connecting seat 51 to ensure sufficient vibration and throwing of the passing wheat biological agent particles.

[0036] The nozzle 4 has a coating liquid branch pipe 41 connected to its inlet (upper end) that penetrates the side wall of the riser 12. A coating liquid main pipe 42, connected to several coating liquid branch pipes 41, is fixedly connected inside the riser 12. The coating liquid main pipe 42 extends downwards from the bottom of the riser 12. The coating liquid flows from the main pipe 42 through the branch pipes 41 and is sprayed into the material channel through the nozzle 4, forming a complete coating liquid supply system. This ensures that each nozzle 4 receives a stable supply of coating liquid, guaranteeing continuous and uniform spraying of the coating liquid into the material channel, which is beneficial for achieving uniform coating and improving coating quality. Utilizing the internal space of the riser 12 to arrange the coating liquid main pipe 42 avoids the need for complex external piping, making the overall layout of the device more compact and simple, effectively saving space, and reducing potential safety hazards to operators from external piping.

[0037] The material channel is equipped with an exhaust system at the top. This system draws in air from the material channel (outdoor air enters through the outlet at the bottom), allowing it to circulate and promptly expel moisture and dust generated within the channel. This facilitates faster drying of the coating solution, resulting in better coating performance and higher efficiency. Furthermore, dust removal improves the working environment (the exhaust outlet can be connected to a dust control device), reducing the health impact on operators and potential damage to the equipment.

[0038] In a further embodiment, an electric heating device 8 is installed in the lower section of the material channel. The material channel is divided into a shorter upper feeding section (half a circle, without vibrating motor 5 and nozzle 4), a longer middle coating operation section (with vibrating motor 5 and nozzle 4 spaced apart), and a lower cooling section (half a circle to one and a half circles, without vibrating motor 5 and nozzle 4). The electric heating device 8 is installed at the junction of the cooling section and the coating operation section. During the exhaust process of the exhaust device, cold air from the outside enters from the lower outlet of the material channel and continuously cools the coated particles in the cooling section. Then, the electric heating device 8 heats the air to form hot air, which enters the coating operation section to accelerate the drying and dehumidification of the particles with the coating liquid, thereby improving the coating efficiency and effect.

[0039] Furthermore, such as Figure 5 As shown, the electric heating device 8 includes a rectangular frame fixedly installed inside the bottom shell 31 and heating wires 82 connected horizontally and vertically within the frame. A material flow gap exists between the bottom of the rectangular frame and the corresponding bottom surface of the bottom shell 31. An electrical connection connector 81 (connected to a power source for power control) is connected to the electric heating device 8, penetrating one side wall of the bottom shell 31. The electric heating device 8 has a simple structure and reasonable arrangement. By energizing the heating wires 82 connected horizontally and vertically within the frame, it heats the surrounding cold air, transforming it into hot air. This effectively accelerates the drying and dehumidification of the coating liquid adhering to the particles, improving the coating effect.

[0040] Furthermore, the exhaust device includes an ejector 7 and an upper cover 33 that seals the upper end of the material channel. The ejector end of the ejector 7 is fixedly connected to the upper cover 33 and communicates with the upper end of the material channel (the upper cover 33 has a hole for the ejector end of the ejector 7 to pass through and be fixed). The high-pressure fluid end of the ejector 7 is connected to a high-pressure air pipe 71. Compressed air is introduced through the high-pressure air pipe 71, and the compressed air, as a power source, is ejected by negative pressure through the ejector 7 to achieve continuous upward discharge of air (moisture, dust) from the material channel. Compared with ordinary fan exhaust methods, its exhaust efficiency is higher, and it has no moving parts, making cleaning and maintenance convenient.

[0041] Furthermore, the side wall of the riser 12 is fixedly connected to an ejector support rod 72 for supporting and positioning the ejector 7. The ejector support rod 72 is fixedly connected to the plug 33 to ensure the reliable installation of the ejector 7, avoid excessive shaking during the ejection process, and ensure the stability and reliability of the exhaust.

[0042] Furthermore, the end of the high-pressure air pipe 71 away from the ejector 7 penetrates the side wall of the riser 12 and is led out downward from inside the riser 12. The high-pressure air pipe 71 is arranged reasonably and compactly, and adopts a hidden arrangement to avoid exposure and mess.

[0043] Furthermore, the ejector 7 outlet end can be connected to a cyclone separator. The dust is removed by the cyclone separator before being discharged, resulting in good dust removal effect and avoiding pollution to the external environment.

[0044] The feed pipe 22 has a rectangular cross-section, and its length direction is consistent with the width direction of the material channel cross-section. A control valve (to control the feed flow) is connected to the lower end. The lower end of the control valve is connected to the upper end of the material channel through a flexible connecting pipe 24 (preferably a corrugated pipe). A rectangular hole is opened on the upper cover 32 to connect to the lower end of the connecting pipe 24. The length direction of the rectangular hole is consistent with the width direction of the material channel cross-section. The connecting pipe 24 has a matching rectangular cross-section. The flow rate of wheat bio-agent granules entering the material channel from the feed hopper 2 can be precisely adjusted by the control valve, thereby better matching the spraying speed of the coating liquid from the nozzle 4 and the overall efficiency of the coating process. This avoids problems such as uneven coating or low coating efficiency caused by too much or too little material. The flexible connecting pipe 24 has a certain degree of elasticity and bendability, which can buffer stress changes caused by equipment vibration or other factors to a certain extent. It prevents problems such as breakage and loosening that are easy to occur at the connection due to rigid connection, ensuring the stability and sealing of the feeding system, so that the material can smoothly enter the material channel from the feeding pipe. The rectangular holes on the top cover 32 can make the granules falling into the material channel more dispersed, avoid accumulation, and improve the adhesion of the subsequent coating liquid.

[0045] Furthermore, the control valve includes a connecting frame 23 connecting the connecting pipe 24 and the discharge pipe 22. An adjustable insert plate 231 is installed on one side of the connecting frame 23, and an insert plate handle 232 is provided on the insert plate 231. The control valve has a simple structure and is easy to operate. By pulling the insert plate 231 with the insert plate handle 232, the discharge flow rate of the control valve can be flexibly adjusted.

[0046] Among them, a support plate 13 is rotatably and adjustablely installed on the upper side of the base 1 (a slewing bearing supporting the support plate 13 is installed on the base 1), and a support plate handle 131 is connected to the side of the support plate 13. The material box 6 has a fan-shaped cross section, and several of them are arranged in a ring on the support plate 13 so that the adjacent material boxes 6 fit together without gaps. The outer side of the material box 6 is connected to the material box handle 61. Rotating the support plate 13 by the handle 131 allows for the rotation and adjustment of the upper material collection box 6, facilitating flexible and convenient switching of the material collection box 6 (located below the material channel outlet). When a material collection box 6 is full of coated wheat bio-agent granules, the empty material collection box 6 (the next one) can be easily moved to the lower outlet of the material channel to continue collection, eliminating the need for frequent machine stops to replace individual material collection boxes 6. This ensures continuous coating operations, improves the flexibility and efficiency of the collection process, and guarantees the continuity of coating operations, thereby further improving overall production efficiency. Furthermore, it optimizes the spatial layout around the device to a certain extent, making the use of space more rational. The material collection boxes 6 are arranged orderly on the support plate 13, preventing clutter and waste of space, and also facilitating the management and handling of the material collection boxes 6 by operators (by pulling the material collection box handle 61).

[0047] In this wheat bio-inoculant coating device, the wheat bio-inoculant granules to be coated are poured into the feeding hopper 2 and continuously conveyed to the upper end of the material channel through the feeding pipe 22. Under the action of gravity, the wheat bio-inoculant granules roll downward along the multi-spiral material channel. Multiple vibrating motors 5 vibrate the bottom shell 31, causing the wheat bio-inoculant granules (which are detached from the ground inside the bottom shell 31) to be thrown up (this can also achieve aerial dispersion of the wheat bio-inoculant granules). The coating liquid is sprayed onto the thrown and dispersed wheat bio-inoculant granules through multiple nozzles 4 (various coating liquids can be arranged according to the falling path) to achieve uniform coating liquid adhesion and improve the coating effect. After multiple throwing and coating operations, the wheat bio-inoculant granules finally fall into the bottom holding box 6 through the lower end of the material channel. This wheat bio-inoculant coating device allows wheat bio-inoculant granules to flow continuously within the material channel, enabling continuous and uninterrupted coating operations and effectively improving coating efficiency and quality. Furthermore, the device features a simple overall structure, compact layout, convenient operation, and good practicality.
