Description

Technical Field

[0001] The present invention belongs to the technical field of soil conditioning, and specifically relates to a coating processing device for a low-temperature slow-release soil conditioner. Background Art

[0002] Soil conditioning, as the name implies, means soil improvement, mainly referring to the action of improving the soil by physical, chemical or microbial means. Currently, soil conditioning can be carried out using soil conditioners;

[0003] The coating processing device for the low-temperature slow-release soil conditioner is a device used for coating the soil conditioner during the production and preparation process of the soil conditioner (coating is to coat the outer surface of the solid preparation with sugar or other film-forming materials in a specific device according to a specific process, so that after drying, it becomes one or several layers of multi-functional protective layers with different thicknesses and different elasticities tightly adhered to the surface). However, during the coating process of the existing coating equipment, most of the solid preparations are stacked together and the coating operation is carried out simultaneously. Although this can greatly improve the coating speed and efficiency, the coating effect is poor, that is, there will be mutual influence between a large number of solid preparations, resulting in incomplete coating and the situation where the solid preparations are adhered together. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a coating processing device for a low-temperature slow-release soil conditioner.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A coating processing device for a low-temperature slow-release soil conditioner, comprising a main body box, a coating material tray, a feeding component and a coating component. The coating material tray is arranged inside the main body box and has an inclination angle to provide a rolling track during the coating process of spherical soil conditioner material packets. The feeding component is arranged above the inside of the main body box for feeding onto the coating material tray. The coating component is arranged inside the main body box for performing coating operations on the soil conditioner on the coating material tray. The feeding component includes a material bin and a lifting feeding mechanism. A material pipe is provided at the bottom of the material bin, and a material passing hole is opened on the inner bottom plate of the material bin. The material passing hole is communicated with the material pipe. The lifting feeding mechanism is used to control the lifting of the material bin to change the distance between the bottom of the material pipe and the coating material tray. When the distance between the bottom of the material pipe and the coating material tray is greater than the diameter of the spherical soil conditioner material, the spherical soil conditioner material inside the material pipe can roll down from the coating material tray. When the device is in use, the spherical soil conditioner material is stored in the material bin. When coating operations are carried out, first the lifting feeding mechanism controls the material bin to rise first and then fall. During this lifting process, the distance between the bottom of the material pipe and the coating material tray changes. When the distance between the bottom of the material pipe and the coating material tray is greater than the diameter of the spherical soil conditioner material, the spherical soil conditioner material at the bottom of the material pipe rolls into the coating material tray. During the rolling process of the spherical soil conditioner material in the coating material tray, the coating component performs coating operations on the spherical soil conditioner material. The feeding of the spherical soil conditioner material from the material pipe onto the coating material tray in this device is provided by the lifting feeding mechanism for a cycle of lifting. Therefore, the feeding of this device is stable, and only one material is fed in one cycle, which can ensure the stability of feeding, so that there is only one material being coated in the coating material tray at a time, avoiding the situation where the spherical soil conditioner materials come into contact in the coating material tray, improving the quality of coating and enabling continuous coating operations (when the spherical soil conditioner material is being coated, it needs to roll in order to be fully coated. When two spherical soil conditioner materials come into contact, they will stick together and be difficult to slide, resulting in the stacking of spherical soil conditioner materials in the coating material tray and preventing subsequent coating operations).

[0007] Preferably, a plurality of rolling grooves are equidistantly arranged along the length direction on the upper surface of the coating material tray. The number of the material pipes is the same as the number of the rolling grooves, and the material pipes and the rolling grooves are in one-to-one correspondence and in the same vertical plane. In this way, a group of coating operations on the spherical soil conditioner materials can be carried out simultaneously, and these coated spherical soil conditioner materials will not affect each other.

[0008] Preferably, the lifting and feeding mechanism includes a chute and a lifting bracket. There are two chutes, symmetrically arranged along the vertical direction on the inner walls of both sides of the main body box. The lifting bracket is arranged inside the main body box. Sliders are installed at both ends of the lifting bracket, and the two sliders are respectively slidably installed in the two chutes. And a cylinder is installed below the inside of the chute. The piston rod at the top of the cylinder is connected to the slider. When the cylinder is operating, it can push the slider to lift and lower in the chute, and the slider is connected to the lifting bracket, so the lifting bracket lifts and lowers synchronously.

[0009] Preferably, the lifting bracket is welded or integrally formed by several circular ring-shaped structures. The material pipe is detachably inserted into the circular ring structure of the lifting bracket. Such a structural setting enables the material pipe and the material bin to be removed from the lifting bracket when lifted upward, facilitating regular cleaning and preventing material adhesion from affecting the discharge.

[0010] Preferably, a clamping groove is opened above the circular ring structure of the lifting bracket, and an assembly clamping block is arranged on the outer wall of the material pipe. The assembly clamping block is clamped in the clamping groove to ensure the stability after the material pipe and the material bin are installed.

[0011] Preferably, the coating assembly includes a low-temperature constant-temperature water bath tank, a main liquid pipe and an air compressor. The low-temperature constant-temperature water bath tank is used to hold the coating solution and is arranged above the main body box. The main liquid pipe is arranged inside the main body box. A atomizing coating nozzle is installed below the main liquid pipe. One end of the main liquid pipe is connected to the peristaltic pump inside the low-temperature constant-temperature water bath tank through a coating solution diversion pipe. The air compressor is arranged above the main body box. The air compressor is connected to the atomizing coating nozzle through a main air pipe. The low-temperature constant-temperature water bath tank holds the coating solution, and the low-temperature constant-temperature water bath tank controls the temperature of the coating solution above the minimum film-forming temperature and close to the minimum film-forming temperature, so that less temperature reduction is required for cooling and film-forming, facilitating subsequent cooling and film-forming. The air compressor provides compressed air to the atomizing coating nozzle, so that the coating solution in the atomizing coating nozzle is atomized and sprayed on the surface of the soil conditioner to realize the coating operation.

[0012] Preferably, several groups of coating assemblies are provided, and several groups of coating assemblies are equidistantly distributed along the length direction of the coating tray. Such a structural setting enables each coating assembly to perform all-round spray coating on the spherical soil conditioner material during the rolling process of the spherical soil conditioner material in the coating tray, improving the coating effect of the spherical soil conditioner material.

[0013] Preferably, a sub-guide air pipe is installed on the air nozzle of the air compressor, and each sub-guide air pipe is controlled to be opened and closed by an electromagnetic valve. Each sub-guide air pipe is respectively connected to the main air pipe in each coating assembly.

[0014] Preferably, a discharge hopper is installed at the low end position of the main body box outside the coating material tray for discharging materials.

[0015] Preferably, the inclination angle of the coating material tray is 1° - 3°. A structure for controlling the inclination angle of the coating material tray is provided below the coating material tray, enabling the coating material tray to change its inclination angle according to actual coating requirements. The greater the inclination angle, the faster the rolling speed of the soil conditioner, the faster the coating speed, and the thinner the coating. The smaller the inclination angle, the slower the rolling speed of the soil conditioner, the slower the coating speed, and the thicker the coating. The structure for controlling the inclination angle of the coating material tray can adopt a lifting cylinder to drive the change of the heights at both ends of the coating material tray to change its inclination angle, or a motor can be installed in the middle of the coating material tray to drive the coating material tray to rotate to achieve the change of its inclination angle.

[0016] In the present invention, the spherical soil conditioner is fed from the material pipe onto the coating material tray by means of the lifting and feeding mechanism for a cycle of lifting. Therefore, the feeding of this device is stable, and only one material is fed within one cycle, which can ensure the stability of feeding, enabling only one material to be coated in the coating material tray at a time, avoiding the situation where the spherical soil conditioner comes into contact within the coating material tray, improving the quality of coating, and realizing continuous coating operation;

[0017] In the present invention, the lifting bracket is formed by welding or integrally molding several circular ring-shaped structures. The material pipe is detachably inserted into the circular ring structure of the lifting bracket. Such a structural setting enables the material pipe and the material bin to be removed from the lifting bracket when lifted upward, facilitating regular cleaning and preventing material adhesion from affecting material discharge.

Detailed implementation mode

[0026] The following combines the attached Figure 1 - attached Figure 7 , and further illustrates the detailed implementation mode of a coating processing device for a low-temperature slow-release soil conditioner of the present invention. The coating processing device for a low-temperature slow-release soil conditioner of the present invention is not limited to the description of the following embodiments.

[0027] Embodiment 1:

[0028] This embodiment provides a specific structure of a coating processing device for a low-temperature slow-release soil conditioner. As Figures 1-7 shown, it includes a main body box 3, a coating material tray 2, a feeding assembly, and a coating assembly. The coating material tray 2 is arranged inside the main body box 3 and has an inclination angle to provide a rolling track during the coating process of spherical soil conditioner materials. The feeding assembly is arranged above the inside of the main body box 3 for feeding materials onto the coating material tray 2. The coating assembly is arranged inside the main body box 3 for coating the soil conditioner on the coating material tray 2. The feeding assembly includes a storage bin 6 and a lifting feeding mechanism. A material pipe 12 is arranged at the bottom of the storage bin 6, and a material passing hole 9 is opened on the inner bottom plate of the storage bin 6. The material passing hole 9 is communicated with the material pipe 12. The lifting feeding mechanism is used to control the lifting of the storage bin 6 to change the distance between the bottom of the material pipe 12 and the coating material tray 2. When the distance between the bottom of the material pipe 12 and the coating material tray 2 is greater than the diameter of the spherical soil conditioner material, the spherical soil conditioner material inside the material pipe 12 can roll down from the coating material tray 2.

[0029] By adopting the above technical solutions:

[0030] When the device is in use, the spherical soil conditioner is stored in the bin 6. When the coating operation is carried out, first, the lifting feeding mechanism controls the bin 6 to rise and then fall. During this lifting process, the distance between the bottom of the feeding pipe 12 and the coating tray 2 changes. When the distance between the bottom of the feeding pipe 12 and the coating tray 2 is greater than the diameter of the spherical soil conditioner, the spherical soil conditioner at the bottom of the feeding pipe 12 rolls into the coating tray 2. During the rolling process of the spherical soil conditioner in the coating tray 2, the coating assembly performs the coating operation on the spherical soil conditioner. In this device, the feeding of the spherical soil conditioner from the feeding pipe 12 to the coating tray 2 is provided by the lifting and lowering of the lifting feeding mechanism for one cycle. Therefore, the feeding of this device is stable, and only one material is fed within one cycle, which can ensure the stability of feeding, so that only one material is coated in the coating tray 2 at a time, avoiding the contact of the spherical soil conditioner in the coating tray 2, improving the quality of coating and enabling continuous coating operation (the spherical soil conditioner needs to roll during coating to achieve full coating. When two spherical soil conditioners come into contact, they will stick together and be difficult to slide, resulting in the stacking of the spherical soil conditioner in the coating tray 2 and unable to perform subsequent coating operations).

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, in this embodiment, a plurality of rolling grooves 10 are equidistantly arranged on the upper surface of the coating tray 2 along the length direction. The number of the feeding pipes 12 is the same as that of the rolling grooves 10, and the feeding pipes 12 and the rolling grooves 10 are in one-to-one correspondence and are located on the same vertical plane, so that the coating operation of a group of spherical soil conditioners can be carried out simultaneously, and these coated spherical soil conditioners will not affect each other.

[0033] The lifting feeding mechanism includes sliding grooves 14 and a lifting bracket 11. Two sliding grooves 14 are provided and symmetrically arranged along the vertical direction on the inner walls of both sides of the main body box 3. The lifting bracket 11 is arranged inside the main body box 3. Sliders 15 are installed at both ends of the lifting bracket 11. The two sliders 15 are respectively slidably installed in the two sliding grooves 14, and a cylinder 13 is installed below the inside of the sliding groove 14. The piston rod at the top of the cylinder 13 is connected to the slider 15.

[0034] The lifting bracket 11 is formed by welding or integrally molding a plurality of annular structures, and the feeding pipe 12 is detachably inserted into the annular structure of the lifting bracket 11.

[0035] A clamping groove 16 is opened above the annular structure of the lifting bracket 11, and an assembly clamping block 17 is arranged on the outer wall of the feeding pipe 12. The assembly clamping block 17 is clamped in the clamping groove 16 to ensure the stability of the feeding pipe 12 and the bin 6 after installation.

[0036] By adopting the above technical solutions:

[0037] When the cylinder 13 is operating, it can push the slider 15 to rise and fall in the chute 14, and the slider 15 is connected to the lifting bracket 11. Therefore, the lifting bracket 11 rises and falls synchronously. When the material pipe 12 and the silo 6 are lifted upward, they can be removed from the lifting bracket 11, which is convenient for regular cleaning to prevent material adhesion from affecting the discharge.

[0038] Embodiment 3

[0039] On the basis of Embodiment 1, in this embodiment, the coating assembly includes a low-temperature constant-temperature water bath 4, a main liquid pipe 20, and an air compressor 5. The low-temperature constant-temperature water bath 4 is used to hold the coating solution and is arranged above the main body box 3. The main liquid pipe 20 is arranged inside the main body box 3. A atomizing coating nozzle 19 is installed below the main liquid pipe 20. One end of the main liquid pipe 20 is connected to a peristaltic pump inside the low-temperature constant-temperature water bath 4 through a coating solution diversion pipe 8. The air compressor 5 is arranged above the main body box 3, and the air compressor 5 is connected to the atomizing coating nozzle 19 through a main air pipe 18.

[0040] A number of coating assemblies are provided, and the number of coating assemblies are equidistantly distributed along the length direction of the coating tray 2. Such a structural arrangement enables each coating assembly to perform omnidirectional spray coating on the spherical soil conditioner material during the rolling process of the spherical soil conditioner material in the coating tray 2, improving the coating effect of the spherical soil conditioner material.

[0041] A sub-guide air pipe 7 is installed on the air nozzle of the air compressor 5, and the on-off of each sub-guide air pipe 7 is controlled by a solenoid valve. Each sub-guide air pipe 7 is respectively connected to the main air pipe 18 in each coating assembly.

[0042] By adopting the above technical solutions:

[0043] The low-temperature constant-temperature water bath 4 holds the coating solution. The low-temperature constant-temperature water bath 4 controls the temperature of the coating solution above the minimum film-forming temperature and close to the minimum film-forming temperature, so that less temperature reduction is required for cooling and film-forming, facilitating subsequent cooling and film-forming. The air compressor 5 provides compressed air to the atomizing coating nozzle 19, causing the coating solution in the atomizing coating nozzle 19 to be atomized and sprayed on the surface of the soil conditioner to achieve the coating operation.

[0044] Embodiment 4

[0045] On the basis of Embodiment 1, in this embodiment, a discharge hopper 1 is installed at the low-end position of the coating tray 2 outside the main body box 3 for discharging.

[0046] The inclination angle of the coating tray 2 is 1° - 3°.

[0047] By adopting the above technical solutions:

[0048] A structure for controlling the inclination angle of the coating material tray 2 is provided below the coating material tray 2, enabling the coating material tray 2 to change its inclination angle according to actual coating requirements. The greater the inclination angle, the faster the rolling speed of the soil conditioner, the faster the coating speed, and the thinner the coating. The smaller the inclination angle, the slower the rolling speed of the soil conditioner, the slower the coating speed, and the thicker the coating. The structure for controlling the inclination angle of the coating material tray 2 can drive the height change of both ends of the coating material tray 2 by a lifting cylinder to change its inclination angle, or can also install a motor in the middle of the coating material tray 2 to drive the coating material tray 2 to rotate to achieve the change of its inclination angle.

[0049] Combined with Embodiment 1 - Embodiment 4, combined Figures 1-7 As shown, the working principle of this application is as follows:

[0050] When the device is in use, the spherical soil conditioner is stored in the silo 6. When coating operation is carried out, first, the lifting feeding mechanism controls the silo 6 to rise first and then fall. During this lifting process, the distance between the bottom of the material pipe 12 and the coating material tray 2 changes. When the distance between the bottom of the material pipe 12 and the coating material tray 2 is greater than the diameter of the spherical soil conditioner, the spherical soil conditioner at the bottom of the material pipe 12 rolls into the coating material tray 2. During the rolling process of the spherical soil conditioner in the coating material tray 2, the coating solution is placed in the low-temperature constant temperature water bath 4. The low-temperature constant temperature water bath 4 controls the temperature of the coating solution above the minimum film-forming temperature and close to the minimum film-forming temperature. The coating solution enters the atomizing coating nozzle 19 through the peristaltic pump, the coating solution diversion pipe 8, and the main liquid pipe 20. And the atomizing coating nozzle 19 atomizes and sprays the coating solution on the surface of the soil conditioner under the action of the compressed air provided by the air compressor 5, cools and forms a film to form a coating. Finally, the spherical soil conditioner with the coating completed is discharged from the discharge hopper 1.

[0051] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present invention.
