Description

Technical Field

[0001] This utility model relates to the technical field of pelleting and coating equipment, specifically to a drum spiral seed pelleting and coating device. Background Technology

[0002] With the development of the times, agricultural technology is also making rapid progress. Seed pelleting and coating technology is a modern agricultural technology that uses physical or chemical methods to coat the surface of seeds with specific materials to form a uniform protective or functional layer. This technology can improve seed shape, size, and surface characteristics, and enhance sowing efficiency, stress resistance, and germination rate. It is an important technical means for modern seed industry and precision agriculture.

[0003] The existing drum spiral seed pelleting and coating device (application number 202210545140.1, a drum spiral seed pelleting and coating device and its control method) uses a spiral structure inside the auger to spray water on the seeds and then rotate them to be coated with powder after inputting the powder. This allows the coating device to continuously pelletize and coat the seeds. However, the auger does not have a cleaning component to quickly clean the inside of the auger. As a result, residual agents and other powders in the auger can affect the pelleting quality of other seeds, thereby affecting the processing of the next type of seed and the processing efficiency of the pelleting and coating device. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a drum spiral seed pelleting and coating device. The existing drum spiral seed pelleting and coating device does not have a cleaning component and does not perform rapid cleaning inside the auger. This causes residual agents and other powders inside the auger to affect the pelleting quality of other seeds, thereby affecting the processing of the next type of seed and the timely processing efficiency of the pelleting and coating device.

[0005] According to the technical solution provided in the embodiments of this application, a drum spiral seed pelletizing and coating device includes a auger, and a cleaning component is provided in the pelletizing chamber inside the auger for cleaning the pelletizing powder remaining after pelletizing in the auger.

[0006] The cleaning component is horizontally arranged along the length of the auger and positioned to the right of the center of the pelletizing chamber, for cleaning the pelletizing chamber;

[0007] The cleaning assembly includes a cleaning mechanism and a drying mechanism. The cleaning pipe and drying pipe of the cleaning mechanism and the drying mechanism are horizontally installed inside the winch, and the drying pipe is arranged above the cleaning pipe so that the cleaning water output from the water tank of the cleaning mechanism is sprayed out from the cleaning pipe to rinse and clean the winch. The fan of the drying mechanism outputs high-temperature air to dry the inner wall of the winch after rinsing.

[0008] Furthermore, the cleaning mechanism includes a water tank, an infusion tube, and a cleaning tube. The cleaning tube is installed in the middle of the support frame and passes through the pelletizing chamber. The infusion tube is connected to the tail end of the cleaning tube, and the other end of the infusion tube is connected to a water pump in the water tank, so that the water pump pumps the cleaning liquid into the cleaning tube.

[0009] Furthermore, the cleaning tube is also equipped with several nozzles, which are arranged side by side and spaced apart, for uniformly spraying the cleaning liquid.

[0010] Furthermore, the drying mechanism includes a fan, an air supply pipe, and a drying pipe. The drying pipe is installed between two support frames, and the air supply pipe is connected to the air inlet of the drying pipe. The other end of the air supply pipe is connected to the fan, so that the fan delivers high-temperature air into the drying pipe.

[0011] Furthermore, the drying tube is provided with a number of drying holes on the contact surface with the auger wall, and the number of drying holes are arranged side by side and spaced apart.

[0012] Furthermore, a brush is installed on the other side of the middle position of the pelletizing chamber. The brush is horizontally arranged through the pelletizing chamber and is used to clean the powder adhering to the wall of the pelletizing chamber. The brush is installed between two second support frames and is fixedly connected to the output end of the rotary drive component so that the rotary drive component drives the brush to rotate, thereby cleaning the residual powder in the pelletizing chamber.

[0013] In summary, the beneficial effects of this application are as follows:

[0014] 1. By installing a cleaning component inside the auger of the drum-type pelletizing and coating device, the cleaning mechanism on the cleaning component is activated, and the cleaning liquid delivered by the water pump in the water tank enters the cleaning pipe and is sprayed out from each nozzle, thereby rinsing and cleaning the inside of the pelletizing chamber of the auger after pelletizing, replacing the original method of stopping the machine for rinsing, thus improving the practicality and convenience of the drum spiral seed pelletizing and coating device.

[0015] Second, by setting a drying mechanism on the cleaning component, the fan on the drying mechanism is started, and high-temperature dry air is transported from the air supply pipe to the drying pipe. The high-temperature dry air is then sprayed out from several drying holes, which dries the water stains remaining in the auger after cleaning. This allows the pelleting and coating device to be cleaned and dried without stopping the machine, thereby improving the pelleting and coating efficiency of the drum spiral seed pelleting and coating device.

[0024] A drum-type spiral seed pelleting and coating device, the structure of which is as follows: Figures 1-4As shown, the device includes a screw conveyor 100, inside which a cleaning component 200 is installed in the pelletizing chamber. This component is used to clean the residual pelletizing powder after pelletizing in the screw conveyor 100, allowing the pelletizing and coating device to clean the inside of the screw conveyor 100 without stopping the machine, thereby improving the practicality and convenience of the pelletizing and coating device. The cleaning component 200 is horizontally arranged along the length of the screw conveyor 100 and is located on the right side of the center of the pelletizing chamber. It is used for rinsing and drying the inside of the pelletizing chamber wall. The cleaning component 200 includes a cleaning mechanism 210 and a drying mechanism 220. The cleaning mechanism 210 and the drying mechanism 220... The cleaning pipe 213 and the drying pipe 223 are horizontally installed inside the auger 100, with the drying pipe 223 positioned above the cleaning pipe 213. This allows the cleaning water output from the water tank 211 on the cleaning mechanism 210 to be sprayed out from the cleaning pipe 213 to rinse and clean the auger 100. Meanwhile, the fan 221 of the drying mechanism 220 outputs high-temperature air to dry the inner wall of the rinsed auger 100. This enables the cleaning component 200 to quickly clean and dry the auger 100 after pelleting and coating, allowing the drum spiral seed pelleting and coating device to quickly pellet and coat the next seed.

[0025] As a preferred embodiment, please refer to Figure 3 and Figure 4 The cleaning mechanism 210 includes a water tank 211, an infusion pipe 212, and a cleaning pipe 213. The cleaning pipe 213 is installed in the middle of the support frame 230 and passes through the pelletizing chamber. The infusion pipe 212 is connected to the tail end of the cleaning pipe 213, and the other end of the infusion pipe 212 is connected to the water pump in the water tank 211. Several nozzles 2131 are also installed on the cleaning pipe 213. The nozzles 2131 are arranged side by side and spaced apart so that the cleaning mechanism 210 on the cleaning assembly 200 is activated. Then, the cleaning liquid delivered by the water pump in the water tank 211 enters the cleaning pipe 213 and sprays out from each nozzle 2131, thereby rinsing and cleaning the inside of the pelletizing chamber of the screw conveyor 100 after pelletizing, replacing the original shutdown for rinsing, and improving the practicality and convenience of the drum spiral seed pelletizing and coating device.

[0026] As a preferred embodiment, please refer to Figure 3 and Figure 4The drying mechanism 220 includes a fan 221, an air supply pipe 222, and a drying pipe 223. The drying pipe 223 is installed between two support frames 230, and the air inlet of the drying pipe 223 is connected to the air supply pipe 222. The other end of the air supply pipe 222 is connected to the fan 221. Several drying holes 2231 are also provided on the contact surface between the drying pipe 223 and the cage wall of the auger 100. The drying holes 2231 are arranged side by side and spaced apart, so that after the fan 221 is started, high-temperature drying gas is delivered to the air supply pipe 222. The valve installed on the air supply pipe 222 is activated to allow the drying gas to enter the drying pipe 223 and spray out from the drying holes 2231 of the drying pipe 223, thereby drying the water stains remaining in the cleaned auger 100, thereby improving the pelleting and coating efficiency of the drum spiral seed pelleting and coating device.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 A brush 300 is installed on the other side of the middle position of the pelletizing chamber. The brush 300 passes through the pelletizing chamber and is set horizontally. The brush 300 is installed between the two second support frames 230 and is fixedly connected to the output end of the rotary drive component so that the rotary drive component drives the brush 300 to rotate, thereby cleaning the residual powder in the pelletizing chamber.

[0028] The working principle of this utility model's drum-type spiral seed pelleting and coating device is as follows:

[0029] After the seeds are pelleted in the drum-type pelleting coating device, some processing powder or chemicals remain inside the auger 100. To avoid affecting the processing efficiency of the pelleting coating device, a cleaning component 200 is installed inside the auger 100. When the auger 100 rotates under the drive of the drive mechanism, the cleaning mechanism 210 on the cleaning component 200 is activated. This causes the cleaning liquid pumped by the water pump in the water tank 211 to enter the cleaning pipe 213 and then spray out from each nozzle 2131, thus cleaning the inside of the pelleting chamber of the rotating auger 100 after the pelleting coating process. Instead of the original shutdown for rinsing, the cleaning solution is rinsed and cleaned. The rinsed cleaning solution is then discharged from the discharge port of the auger 100 by the conveyor plate with a spiral structure, thereby improving the practicality and convenience of the drum spiral seed pelleting and coating device. At the same time, the fan 221 on the drying mechanism 220 is started, which transports high-temperature dry air from the air supply pipe 222 to the drying pipe 223, and then sprays the high-temperature dry air out from several drying holes 2231, thereby drying the water stains remaining in the auger 100 after cleaning, thereby improving the pelleting and coating efficiency of the drum spiral seed pelleting and coating device.

[0030] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
