Description

Technical Field

[0001] The utility model belongs to the technical field of powder pesticide production feeding, in particular to a screw type powder feeding device. Background Art

[0002] Powdered pesticides are a common form of agricultural chemicals, usually used for plant protection and pest control. Powdered pesticides are usually made by mixing active ingredients and some auxiliary ingredients in powder form. These powders usually need to be mixed with water into a suspension or suspension before use, and then sprayed on crops. They are widely used in agricultural applications. During the production and processing of powdered pesticides, it is generally necessary to assist in the loading and transportation of powder materials into the interior of the equipment.

[0003] A Chinese patent with the publication number "CN219620406U" discloses a powder feeder, which includes a supporting frame, a feeding sleeve is arranged inside the supporting frame, one end of the feeding sleeve is fixedly connected to a discharge port, a filter is fixedly connected inside the discharge port, a fixing rod is arranged above the filter, the fixing rod is fixedly connected to the discharge port, an inner sleeve ring is fixedly connected to the middle of the filter, a No. 2 transmission motor is arranged at the lower end of the inner sleeve, and a crushing rod is fixedly connected to the output end of the No. 2 transmission motor through the No. 2 transmission motor. In the utility model, the filter and the crushing rod are arranged, so that when the powder is transferred and fed, the agglomerated powder can be broken through the rotation of the crushing rod and the fixing rod, so that the agglomerated powder is re-formed into powder, and is screened and filtered through the filter, so as to facilitate the subsequent processing of the powder for convenient use.

[0004] During the use of the above-mentioned device, although it can assist in the loading and transportation of powders, during its specific use, it can only load at a single height. When the equipment or the required loading height changes, it can be seen that its overall loading adaptability is poor, and during its use, the stirring structure is arranged inside the discharge port. During the loading period, the discharge port has a stirring structure, and the stirring structure is very easy to cause blockage at the discharge port. Even if it is not blocked, it will lead to low discharge efficiency at the discharge port, so it needs to be improved. Utility Model Content

The conveying auger 54 rotates to transmit the powder inside the transmission sleeve 51 toward the discharge pipe 55. The powder material enters the discharge pipe 55 and can be quickly discharged. During the transmission of the powder material, if the height is not suitable, the telescopic cylinder 72 can be used to operate. By operating the telescopic cylinder 72 and cooperating with the first articulated seat 71 and the second articulated seat 73, the transmission sleeve 51 can be pushed to rotate between the inner sides of the mounting plate 4 of the groove 3 by the telescopic cylinder 72. The height of the discharge pipe 55 can be flexibly adjusted by rotating the transmission sleeve 51, so that the device can be flexibly adjusted to adapt to the transmission of powders at different heights. The device adopts a design that can adjust the height, so that the device can flexibly adapt to the transportation requirements of different heights, and can meet the requirements of different process flows and equipment layouts. Compared with the independent transportation equipment required for different heights, the use of a device that can transport at different heights can save space and make the production line layout more compact. The integration of the function of transporting at different heights can reduce the number of equipment, thereby reducing the cost of equipment procurement, installation and maintenance. It can also realize automated material transportation, improve production efficiency, and reduce labor costs. A reasonably designed conveying device can reduce energy consumption and reduce the impact on the environment.

[0033] By setting the feeding mechanism 6, during use, powder material can be added to the inside of the guide bucket 64, and the powder material can be transported to the inside of the upper hopper 62 through the auxiliary guidance of the guide bucket 64. After the conveying guidance of the upper hopper 62, the powder material can be added to the inside of the feeding tube 61 through the upper hopper 62, and the material can be added to the inside of the transmission sleeve 51 by conveying through the feeding tube 61. During this period, the second motor 632 is used to operate, and the second motor 632 drives the rotating shaft 633 to rotate. The rotation of the rotating shaft 633 can drive the spiral blade 634 to rotate, and the spiral blade 634 The rotation can assist in stirring the powder inside the feeding hopper 62, and at the same time, a downward driving force can be applied to enable the powder material to quickly enter the feeding tube 61. During the feeding process, the rotating shaft 633 drives the mincing frame 635 at the bottom to rotate. The rotation of the mincing frame 635 can cooperate with the spiral blades 634 to assist in stirring, so that the powder can be stirred and broken up, achieving a better stirring effect and avoiding the phenomenon of powder blockage.
