Description

Technical Field

[0001] The invention relates to the technical field of diced potato seed potato processing equipment, in particular to a powder spraying device for a diced potato seed potato mixing machine. Background Art

[0002] In recent years, potatoes have become the fourth largest staple food crop in my country, but my country's potato yield per unit area is still low. One of the main reasons is the lack of qualified seed potatoes. Traditional potato planting mainly uses cut seed potatoes for sowing. However, if diseased potatoes are encountered during the cutting process, the cutting cutter will spread the pathogens to other healthy potato pieces, affecting the planting quality and causing a decrease in the emergence rate after sowing. This is also one of the main reasons for the low potato yield per unit area. By disinfecting and powdering the cut seed potatoes before sowing, the quality of the seed potatoes can be effectively guaranteed. Even if there are diseased potatoes, they will not affect other healthy cut potatoes, which helps to improve the emergence rate and ensure high and stable yields. Therefore, seed dressing and dusting of cut potatoes is an important way to increase potato yields.

[0003] At present, although there are powder spraying devices for other crop seeds, these devices are not suitable for the powder spraying process of potato seed mixing machines due to the differences in material properties of powder and seeds. The powder used in potato seed mixing machines is usually talcum powder, but the existing powder spraying devices are not specially designed to be adaptable. If it is used for powder spraying in potato seed mixing machines, it may affect the processing quality of cut potatoes and cause certain economic losses. At the same time, because talcum powder is easily affected by storage time and air humidity, it is easy to harden, resulting in the inability to achieve uniform powder spraying of cut potatoes; for this reason, a powder spraying device for potato cut seed potato seed mixing machine is proposed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a powder spraying device for a potato cutting and seed potato mixing machine, which can break up compacted powder and make the powder fine and uniform, thereby ensuring a uniform and stable supply of powder during the powder spraying process; improve the powder coating uniformity of the cut potatoes after spraying and sterilization, thereby ensuring the processing quality of the potato cutting and seed potatoes.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a potato cutting seed potato seed mixing machine powder spraying device, comprising a powder barrel, a barrel cover is provided on the upper part of the powder barrel, a pneumatic motor and a powder spraying pump are provided on the top of the barrel cover, the output end of the pneumatic motor is connected to a stirring rod through a set screw, a spiral blade is provided at the lower end of the stirring rod, a hole plug is provided on the top of the barrel cover away from the powder spraying pump, a vibration plate is provided on the inner side wall of the powder barrel, and a vibration assembly is provided at the bottom of the vibration plate.

Two U-shaped plates are equidistantly arranged at the bottom of the vibration plate, and bearings are arranged on the U-shaped plates. A shaft is arranged between the bearings, and two keys are equidistantly arranged on the outer side of the shaft, and the keys are symmetrically distributed. Eccentric wheels are arranged outside the keys, and the middle part of the shaft is connected to the driving blade via two setscrews.

[0007] Preferably, a powder spray hose is provided at the rear port of the powder spray pump, a throttle valve 2 is provided at the front port and the upper port of the powder spray pump, an air pipe 2 and an air pipe 5 are provided on the throttle valve 2, the air pipe 2 and the air pipe 5 are respectively connected to the air pipe 1 connected to the air compressor through a three-way air pipe, and a powder suction pipe is provided at the input end of the powder spray pump.

[0008] Preferably, a plurality of pores are formed on the surface of the vibration plate, and the pores are distributed radially.

Compared with the existing technology, this solution avoids the uneven powder spraying caused by powder agglomeration in traditional equipment, and improves the stability and efficiency of the operation.

[0015] 2. The present invention combines the powder spraying pump with the negative pressure principle, uses the difference in air flow velocity to generate negative pressure, successfully sucks talcum powder into the powder spraying pump through the powder suction pipe, and accelerates the air flow in the powder spraying pump, so that the powder can be quickly and efficiently sprayed onto the cut seed potatoes. This solution significantly improves the accuracy and uniformity of powder spraying, and avoids the shortcomings of powder deposition and uneven spraying compared to the solution of using traditional air pressure powder spraying in the prior art.

[0016] 3. The present invention is reasonably designed, making full use of the lubricity of talcum powder. By cooperating with the vibration device and the spiral blade, it not only effectively improves the efficiency of the powder spraying process, but also greatly reduces the occurrence of equipment failures. Compared with the more complex and unstable powder spraying device in traditional technology, the present invention provides a more reliable and simple solution, which significantly improves the service life and maintenance convenience of the equipment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Please see attached Figure 1 -Attached Fig. 9 The embodiment of the present invention provides a powder spraying device for a potato cutting and seed potato mixing machine, comprising a powder barrel 14, which is a container for storing and containing powder materials. A barrel cover 21 is arranged on the upper part of the powder barrel 14, which closes the structure of the upper part of the powder barrel 14 to prevent powder from overflowing. An air motor 1 and a powder spraying pump 5 are arranged on the top of the barrel cover 21. The air motor 1 is driven by air pressure to work, and the powder spraying pump 5 draws powder from the powder barrel 14 and sprays it through a pipeline. The powder spraying pump 5 utilizes the Venturi effect. The pressure is small where the flow rate is large, so negative pressure is generated, and the powder is sucked into the powder spraying pump 5. Then, under the action of the high-speed airflow, the powder is blown out; by adjusting the opening and closing amplitude of the throttle valve 22, the suction force of the powder spraying pump 5 can be adjusted, and the output of the air motor 1 can be adjusted. The outlet end is connected to the stirring rod 13 through a set screw 15, and the power of the pneumatic motor 1 is transmitted to the stirring rod 13. The spiral blade 31 is arranged at the lower end of the stirring rod 13, and the powder is evenly distributed by rotation. The lower end of the stirring rod 13 is provided with a spiral blade 31, and a hole plug 20 is provided on the top of the barrel cover 21 on the side away from the powder pump 5, which is used to control the discharge of gas or materials. The inner wall of the powder barrel 14 is provided with a vibration plate 7, and the vibration plate 7 is used to help the powder flow by vibration. The bottom of the vibration plate 7 is provided with a vibration component 30, which improves the fluidity and uniform distribution of the powder by vibration. A plurality of air holes 32 are provided on the surface of the vibration plate 7, and the air holes 32 are radially distributed. The diameter of the air holes 32 on the vibration plate 7 is 1 mm;

[0029] The vibration assembly 30 includes a shaft 8, a U-shaped plate 9, an eccentric wheel 10, a driving blade 11, a key 12, a second set screw 28, and a bearing 29. Two U-shaped plates 9 are equidistantly arranged at the bottom of the vibration plate 7, and the U-shaped plates 9 are each provided with a bearing 29. The shaft 8 is arranged between the bearings 29. Two keys 12 are equidistantly arranged on the outer side of the shaft 8, and the keys 12 are symmetrically distributed. The eccentric wheels 10 are arranged outside the keys 12. The middle part of the shaft 8 is connected to the driving blade 11 through the second set screw 28.

[0030] Among them, the distance between the U-shaped plate 9 and the driving blade 11 is 30 cm, the distance between the U-shaped plate 9 and the eccentric wheel 10 is 15 cm, and the shaft 8 is axially positioned with the bearing 29 and the U-shaped plate 9 through the shaft retaining ring 26 and the hole retaining ring 27, and the bearing 29 supports the shaft 8 to rotate;

[0031] The rear port of the powder spraying pump 5 is provided with a powder spraying hose 33, and the powder spraying hose 33 is used to spray powder. The front port and the upper port of the powder spraying pump 5 are provided with a throttle valve 22. The function of the throttle valve 22 is to control the flow rate, flow velocity and pressure of the fluid gas or liquid, which is usually achieved by adjusting the size of the channel through which the fluid passes through the valve. The throttle valve 22 is provided with an air pipe 24 and an air pipe 5 25, and the air pipe 24 and the air pipe 5 25 are used to circulate gas. The air pipe 24 and the air pipe 5 25 are respectively connected to the air pipe 1 3 connected to the air compressor through the three-way air pipe 24. The input end of the powder spraying pump 5 is provided with a powder suction pipe 6, and the powder suction pipe 6 is used to suck out the powder;

[0032] The device utilizes the characteristics of talcum powder and high-pressure gas to drive the pneumatic motor 1 to drive the spiral blade 31 to stir and the vibration component 30 to vibrate, thereby eliminating the compacted powder. The powder spraying pump 5 utilizes negative pressure to suck the powder in the powder barrel 14 from the powder suction pipe 6 and spray it out through the powder spraying hose 33, thereby providing high-quality and uniform powder for potato cutting and seed potato seed dressing.

[0033] Please see attached Figure 1 The pneumatic motor 1 is arranged on the top of the flange seat 23, and the flange seat 23 is connected to the barrel cover 21 through the bolt fastener group 2, which ensures the stable installation of the pneumatic motor 1 and avoids loosening during use.

[0034] Please see attached Figure 3 The front end of the pneumatic motor 1 is connected with an air valve 16 and an air pipe 3 17 which are connected with the air compressor. The pneumatic motor 1 is connected with the air pipe 3 17 through the air valve 16 to control the air flow and air pressure. A circular hole is provided on the barrel wall between the inner bottom wall of the powder barrel 14 and the bottom of the vibration plate 7 for installing a throttle valve 19, and a throttle valve 19 is installed outside the circular hole. An air pipe 4 18 is provided at the top port of the throttle valve 19, and the pressure in the barrel is controlled by the throttle valve 19 and the air pipe 4 18;

[0035] Please see attached Figure 5 A shaft retaining ring 26 is provided between the inner ring and the outer ring of the bearing 29, and a hole retaining ring 27 is provided on the inner ring of the bearing 29 to ensure the stability of the bearing 29 during use and to prevent powder from directly entering the interior of the bearing 29;

[0036] Working principle: First, before spraying powder, pour the powder into the powder barrel 14, and then install the barrel cover 21 on the powder barrel 14. When spraying powder, open the air valve 16 connected to the air compressor, so that the high-pressure gas drives the air motor 1 to rotate through the air pipe 3 17, and drives the stirring rod 13 and the spiral blade 31 to rotate; open the throttle valve 19 connected to the air compressor, so that the high-pressure gas blows through the air pipe 4 18 to drive the fan blade 11 to rotate, and drives the shaft 8 and the eccentric wheel 10 to rotate; open the throttle valve 2 22 connected to the air compressor, and under the action of high-pressure gas, use the Venturi effect. The Venturi effect refers to the phenomenon that the flow rate increases and the pressure decreases when the fluid passes through the contraction of the pipe cross section. The powder enters the powder pump 5 through the powder suction pipe 6, and is finally sprayed out through the spray nozzle through the powder hose 33, and finally sprayed to the cut potatoes through the spray nozzle;

[0037] The pneumatic motor 1 is driven by high-pressure gas to drive the spiral blade 31 to stir and the vibration component 30 to vibrate. At the same time, a part of the high-pressure gas is blown toward the powder from the air hole 32 to help break up the lumps and keep the powder in a uniform and loose state. Inside the powder spraying pump 5, negative pressure is generated due to the difference in air flow rate. The talcum powder is sucked into the powder spraying pump 5 through the powder suction pipe 6 and is quickly blown toward the front port of the powder spraying pump 5 under the action of the air flow. Then it continues to move through the powder spraying hose 33 and is finally evenly sprayed toward the cut potatoes through the nozzle.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
