Abstract
Description
Technical Field
[0001] This utility model specifically relates to a feeding device for a fertilizer and pesticide elevator. Background Technology
[0002] Elevators are large mechanical devices that transport materials by changing their potential energy. In the process of producing pesticides and fertilizers, elevators are one of the essential pieces of machinery.
[0003] In existing fertilizer and pesticide production lines, damp raw materials (such as organic matter, urea granules, or bacterial residue) often experience spiral caking due to their high moisture content before entering the elevator: the material adheres to the surface of the continuous spiral blades, causing a sudden increase in pushing resistance, increased motor load, and even stalling and shutdown. Utility Model Content
[0004] The purpose of this utility model is to provide a feeding device for a fertilizer and pesticide elevator to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a fertilizer and pesticide elevator, comprising a feeding cylinder, wherein a spiral shaft that can rotate around its own axis is provided inside the feeding cylinder, and continuous spiral blades are fixed on the spiral shaft, wherein the continuous spiral blades are used to push the fertilizer and pesticide raw materials along the axial direction of the feeding cylinder, and a hot air supply unit is provided outside the feeding cylinder, so that the hot air heats and dries the raw materials while they are being pushed by the spiral.
[0006] Preferably, the hot air supply unit includes an annular hot air sleeve fitted around the periphery of the conveying cylinder and a hot air generator that supplies hot air to the annular hot air sleeve.
[0007] Preferably, the hot air generator is an electric heating fan.
[0008] Preferably, it also includes a frame, which is a frame structure, and a motor is mounted on the frame.
[0009] Preferably, the motor power output end is connected to a transmission belt via a first pulley, and the other end of the transmission belt is connected to a spiral shaft via a second pulley.
[0010] Preferably, the frame is provided with a bearing seat for supporting and cooperating with the rotation of the screw shaft.
[0011] Preferably, the upper surface of the conveying cylinder has a feed inlet.
[0012] The technical effects and advantages of this utility model are as follows: The feeding device of this fertilizer and pesticide elevator has an annular gap hot air sleeve set on the outer periphery of the conveying cylinder. Hot air directly penetrates the material layer through the air distribution holes in the cylinder wall, so that the spiral pushing and heating drying are completed simultaneously, eliminating the need for a front-end dryer. When the spiral shaft rotates, the continuous spiral blades generate shearing and tumbling action on the material. Combined with the hot air flushing, the surface moisture can be quickly reduced. There is no wet material adhering to the surface of the continuous spiral blades. The drying process is completed in a relatively closed conveying cylinder, which occupies a small area and effectively improves the overall practicality. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] refer to Figure 1 , Figure 2 and Figure 3As shown, the system includes a conveying cylinder 1, inside which is a spiral shaft 2 that can rotate around its own axis. Continuous spiral blades 3 are fixed on the spiral shaft 2. The continuous spiral blades 3 are used to push the raw materials of the fertilizer and pharmaceutical along the axial direction of the conveying cylinder 1. A hot air supply unit is provided outside the conveying cylinder 1, so that hot air heats and dries the raw materials while they are being spirally pushed. An annular gap hot air sleeve 4 is provided around the outer periphery of the conveying cylinder 1, and the hot air directly penetrates the material layer through the air distribution holes in the cylinder wall, so that the spiral pushing and heating / drying are completed simultaneously, eliminating the need for a front-end dryer. 2. During rotation, the continuous spiral blades 3 shear and tumble the material. Combined with hot air flushing, the surface moisture can be quickly reduced. There is no wet material adhering to the surface of the continuous spiral blades 3. The drying process is completed in the relatively closed conveying cylinder 1, which occupies a small area and effectively improves the overall practicality. The cylinder wall of the conveying cylinder 1 has several air distribution holes. The hot air in the annular hot air sleeve 4 enters the interior of the conveying cylinder 1 evenly through the air distribution holes, thereby completing the heating of the raw materials. The diameter of the air distribution holes is smaller than the average particle size of the fertilizer raw materials to prevent material leakage.
[0020] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the hot air supply unit includes an annular hot air sleeve 4 surrounding the conveying cylinder 1 and a hot air generator 5 that supplies hot air to the annular hot air sleeve 4. The annular hot air sleeve 4 is formed by two semi-cylindrical segments joined together by quick-release locking clips to form an annular cavity. The mating surface is lined with a high-temperature resistant silicone sealing strip. The outlet of the hot air generator 5 can be tangentially connected to the annular cavity through a flexible high-temperature resistant corrugated pipe to reduce vibration transmission. The semi-cylindrical segment structure allows maintenance personnel to open the annular sleeve, clean the wall residue, or clear the air distribution holes without disassembling the conveying cylinder 1, ensuring continuous production. The flexible corrugated pipe absorbs the vibration of the motor 7 and the fan, preventing fatigue cracking of the annular sleeve weld. The hot air generator 5 is an electrically heated fan. It also includes a frame 6, which is a frame structure. The motor 7 is mounted on the frame 6, and a vibration damping pad is added between the motor 7 and the frame 6 to reduce noise and improve the workshop environment. The power output end of the motor 7 is connected to a transmission belt 8 via a first pulley. The other end of the transmission belt 8 is connected to the screw shaft 2 via a second pulley. The frame 6 is provided with a bearing seat 9 for supporting and cooperating with the rotation of the screw shaft 2. The bearing seat 9 supports the screw shaft 2, making its rotation more stable. The second pulley is located on the screw shaft. The upper surface of the feeding cylinder 1 has a feed inlet 10, which is eccentrically funnel-shaped. A PTFE non-stick coating can be sprayed on its inner wall to prevent wet material from bridging.
[0021] When in use, first start the hot air generator 5 and keep it running. Start the motor 7 to enter normal speed and continuously feed the raw materials of medicine and fertilizer into the feed port 10. The amount of material should be gradually increased from small to large to the rated capacity so that the hot air and the thickness of the material layer are matched synchronously. Under the drive of the motor 7, the transmission belt 8 drives the spiral shaft 2 to rotate, so that the continuous spiral blades 3 can move the raw materials. During the transmission process, the raw materials can be dried by hot air and finally transferred to the elevator to complete the feeding and transportation.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
