Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, and particularly relates to a raw material sieve for the processing of anti-pest medicine fertilizers. Background Art

[0002] Pests and diseases are the main limiting factors for high-yield and high-quality crops. Every year, due to ineffective pest control, huge losses are caused. The greatest difficulty in pest control is that the occurrence laws and occurrence times are not easy to master and control, especially for underground pests and after the crops grow into adult plants, the control difficulty increases. In order to facilitate the pest control of plants, special anti-pest medicine fertilizers are generally used to spray and protect plants and kill pests and diseases.

[0003] In the production of existing anti-pest medicine fertilizers, the raw materials of anti-pest medicine fertilizers are screened. Generally, a special sieve is used for screening operations. In the existing raw material screening device for anti-pest medicine fertilizers, the commonly used one is to use a vibrating screen machine for screening. It mainly screens through a sieve mesh and provides vibration through a vibrating motor to assist the sieve mesh in quickly screening.

[0004] In the actual use of the above-mentioned existing raw material sieve for the processing of anti-pest medicine fertilizers, the applicant found that: when screening the raw materials of medicine fertilizers, the staff will first put the raw materials of medicine fertilizers into the feeding hopper, and the raw materials of medicine fertilizers will continuously fall from the discharge port onto the sieve mesh for screening. However, when the feeding device of the above-mentioned sieve is screening, the feeding amount cannot be accurately controlled, which is likely to cause the feeding amount to be too large and exceed the screening limit or the feeding amount to be too small and cause the sieve mesh performance to be excessive. At the same time, when feeding, the materials are very unevenly distributed on the sieve mesh. At this time, the sieve needs to first shake the materials loose before stable screening can be carried out, and the screening efficiency will be reduced. In order to solve the above-mentioned problems, a raw material sieve for the processing of anti-pest medicine fertilizers is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a raw material sieve for the processing of anti-pest medicine fertilizers in order to solve the above-mentioned problems.

The lower parts of the connecting plates are fixedly installed on the vibration screening machine. A plurality of material distributing protrusions are fixedly connected to the bottom of the inner cavity of the L-shaped material guiding pipe close to the discharge port.

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following will be combined with Figures 1-5 A raw material sieve for processing anti-disease and insect pest medicine fertilizers in the embodiments of the present utility model will be described in detail.

[0025] Embodiment

[0026] A raw material sieve for processing anti-disease and insect pest medicine fertilizers provided by an embodiment of the present utility model, referring to Figures 1 to 5 as shown, includes a chassis 1, on which a vibrating screening machine 2 for anti-disease and insect pest medicine fertilizer raw materials is fixedly installed. A material guide 3 is arranged on the vibrating screening machine 2, and a feeding assembly 4 is installed on the chassis 1. In this structure, the feeding assembly 4 is used to feed materials into the vibrating screening machine 2, and then the material guide 3 guides and disperses the medicine fertilizer raw materials, so that the anti-disease and insect pest medicine fertilizer raw materials are evenly distributed on the vibrating screening machine 2, and then the vibrating screening machine 2 can perform screening operations on the anti-disease and insect pest medicine fertilizer raw materials.

[0027] Referring to Figures 1 to 5As shown in the figure, the vibration screening machine 2 includes a support box 14. A connecting plate 12 is fixedly installed on the support box 14. A plurality of screening meshes 15 are fixedly installed inside the support box 14 in an up-and-down arrangement. Four ends of the bottom of the support box 14 are fixedly connected with convex feet 16. Springs 17 are fixedly installed at the bottoms of the convex feet 16. The bottom ends of the springs 17 are fixedly installed on the bottom frame 1. A vibration motor 18 is fixedly installed at the bottom of the support box 14. The above components constitute a vibration screening structure for the anti-disease and insect pest medicine and fertilizer raw materials. Among them, the vibration motor 10 cooperates with the springs 17 to make the support box 14 vibrate regularly, thereby driving the materials on the screening mesh 15 to roll and screen, so as to complete the vibration screening of the anti-disease and insect pest medicine and fertilizer raw materials.

[0028] Reference Figures 1 to 5 As shown in the figure, both the support box 14 and the screening mesh 15 are in an inclined state. The inclined support box 14 and screening mesh 15 enable the anti-disease and insect pest medicine and fertilizer raw materials to roll and screen towards the lower place, thus facilitating the feeding and collection of the anti-disease and insect pest medicine and fertilizer raw materials after screening.

[0029] Reference Figures 1 to 5 As shown in the figure, the aperture of each screening mesh 15 is different, and the aperture of the screening mesh 15 decreases successively from top to bottom. The screening meshes 15 with different apertures can perform multi-level screening on the anti-disease and insect pest medicine and fertilizer raw materials.

[0030] Reference Figures 1 to 5 As shown in the figure, the feeding assembly 4 includes a portal frame 5. A hopper 6 is fixedly installed at the top of the portal frame 5. A discharge pipe 7 is fixedly connected to the lower part of the hopper 6. A distributing cylinder 8 is rotatably connected to the discharge pipe 7. A distributing groove 9 is formed on the distributing cylinder 8. A motor 10 with adjustable speed is fixedly installed on the discharge pipe 7. The motor 10 is connected to the distributing cylinder 8 through an output shaft. With this structure, personnel can first put the anti-disease and insect pest medicine and fertilizer raw materials into the hopper 6. Then, the anti-disease and insect pest medicine and fertilizer raw materials in the hopper 6 will fall into the distributing groove 9 of the distributing cylinder 8. Then, start the motor 10 to drive the distributing cylinder 8 to rotate, so as to turn the distributing groove 9 downward, and thus the anti-disease and insect pest medicine and fertilizer raw materials in the distributing groove 9 will fall from the discharge port of the discharge pipe 7. The entire feeding device can achieve equal and continuous feeding of the anti-disease and insect pest medicine and fertilizer raw materials. The entire device can more accurately control the feeding and screening of the anti-disease and insect pest medicine and fertilizer raw materials, avoid the influence on the screening of the vibration screening machine 2 caused by unstable feeding amount, and can control the speed of the motor 10 to adjust the appropriate feeding frequency, so as to be adapted to use according to the actual screening capacity of the vibration screening machine 2.

[0031] It should be noted that: The speed of the motor 10 is controlled by a frequency converter. The specific adjustment control components and control systems have been made public, so they will not be introduced in detail here.

[0032] Reference Figures 1 to 5As shown in the figure, the material guide 3 includes an L-shaped material guide pipe 11. Connecting plates 12 are fixedly installed on both sides of the L-shaped material guide pipe 11. The lower parts of the connecting plates 12 are fixedly installed on the vibration screening machine 2. A plurality of material distributing protrusions 13 are fixedly connected to the bottom of the inner cavity of the L-shaped material guide pipe 11 near the discharge port. In this structure, when the feeding component 4 feeds the anti-insect and disease-resistant medicine fertilizer raw materials into the L-shaped material guide pipe 11, with the vibration of the vibration screening machine 2, the anti-insect and disease-resistant medicine fertilizer raw materials will be vibrated and dispersed, and the anti-insect and disease-resistant medicine fertilizer raw materials are dispersed and discharged from the discharge port of the L-shaped material guide pipe 11 through the material distributing protrusions 13, so that the anti-insect and disease-resistant medicine fertilizer raw materials are evenly distributed on the screen 15, thereby improving the screening efficiency.

[0033] Reference Figures 1 to 5 As shown in the figure, the discharge hole of the discharge pipe 7 extends into the L-shaped material guide pipe 11, and the upper opening size of the L-shaped material guide pipe 11 is larger than the lower size of the discharge pipe 7. This structural design enables the discharge pipe 7 to accurately feed the anti-insect and disease-resistant medicine fertilizer raw materials into the L-shaped material guide pipe 11. At the same time, the L-shaped material guide pipe 11 is larger than the discharge pipe 7, providing a moving space for the vibration of the L-shaped material guide pipe 11 and avoiding interference between the L-shaped material guide pipe 11 and the discharge pipe 7.

[0034] Reference Figures 1 to 5 As shown in the figure, the material distributing protrusions 13 are arranged in two rows, and the two rows of material distributing protrusions 13 are arranged in a staggered manner. With the cooperation of the vibration of the two rows of material distributing protrusions 13, the anti-insect and disease-resistant medicine fertilizer raw materials can be dispersed and discharged.

[0035] It should be noted that: the screening device disclosed in the above embodiment is applied to the screening and processing of anti-insect and disease-resistant medicine fertilizer raw materials, and belongs to the field of anti-insect and disease-resistant medicine fertilizer processing equipment.

[0036] The implementation principle of a raw material screening device for processing anti-insect and disease-resistant medicine fertilizers in an embodiment of the present application is as follows: When in use, the operator first starts the vibration motor 10 in cooperation with the spring 17 to make the support box 14 vibrate regularly, thereby driving the screen 15 to vibrate regularly. The operator first feeds the anti-insect and disease-resistant medicine fertilizer raw materials into the hopper 6, and then the anti-insect and disease-resistant medicine fertilizer raw materials in the hopper will fall into the distribution groove 9 of the distribution cylinder 8. Then, the motor 10 is started to drive the distribution cylinder 8 to rotate, so that the distribution groove 9 rotates downward, and the anti-insect and disease-resistant medicine fertilizer raw materials in the distribution groove 9 fall from the discharge port of the discharge pipe 7 and enter the L-shaped material guide pipe 11. At this time, with the vibration of the vibration screening machine 2, the anti-insect and disease-resistant medicine fertilizer raw materials will be vibrated and dispersed, and the anti-insect and disease-resistant medicine fertilizer raw materials are dispersed and discharged from the discharge port of the L-shaped material guide pipe 11 through the material distributing protrusions 13, so that the anti-insect and disease-resistant medicine fertilizer raw materials are evenly distributed on the screen 15, and then the vibrating screen 15 can perform screening operations on the anti-insect and disease-resistant medicine fertilizer raw materials.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
