Description

Technical Field

[0001] The invention relates to the field of circulating combustion water heating furnaces, and more specifically, to a device and method for finely screening and classifying seed breeding particles. Background Art

[0002] Seed selection and screening is an important step in seed cleaning and selection. It mainly uses sieves or other screening equipment to classify seeds into different grades or categories according to their shape, size, weight and other characteristics.

[0003] At present, it is found in the seed screening operation that most of the existing screening methods use air blowing to blow out inferior seeds to achieve the separation effect. However, a large number of seeds are piled up together, and the piled seeds form a barrier to each other, which makes it impossible to blow out the inferior seeds directly, and also causes some qualified seeds to be blown away, which affects the screening efficiency and causes a lot of cost losses.

[0004] In order to solve the above problems, the present application proposes a device and method for fine screening and classification of seed breeding particles. Summary of the invention

[0005] The object of the present invention is to provide a device and method for fine screening and classification of seed breeding particles, which can solve the problems in the prior art by evenly dispersing the material and performing air blast screening.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A device for fine screening and classification of seed breeding particles comprises: a screening machine, a storage part and a temporary storage part, wherein the seeds are screened inside the screening machine and classified and stored in the storage part and the temporary storage part, and finally discharged from a discharge pipe; a plurality of conical screening nets are layeredly installed near the center of the screening machine, and the mesh size gradually decreases from top to bottom, and is used to screen and classify seeds of different sizes; a receiving platform is arranged on the inner side of the storage part, which is located at the middle height of the conical screening net and is used to receive the screened inferior seeds; a plurality of paddles are attached to the circumferential distribution of the conical screening net through an inclined installation structure, and are used to dredge the mesh holes to prevent the seeds from being stuck; a segmented shaft frame is layeredly connected to the upper end of the conical screening net, and a top seat is installed on its upper end through a rod body mechanism on the inner side of the top cover of the screening machine; a driving motor is built-in at the lower end of the screening machine, which is installed inside the receiving slot and is used to apply wind force to screen the inferior seeds, and a rotating rod is arranged inside the shaft frame coaxial with the driving motor.

[0008] Through the above technical solution, when screening seeds, the top seat is used to evenly disperse them circumferentially, and the wind force applied by the driving motor during their falling can be used to directly blow out the mixed inferior seeds. Compared with the existing screening method, it can effectively avoid the situation where inferior seeds accumulate inside qualified seeds and cannot be directly separated, and at the same time prevent the situation where qualified seeds are carried away and separated, causing cost waste.

[0009] A fixing frame is provided at the lower end of the conical screening net and docked with the temporary storage part, and the diameter of the fixing frame is smaller than the diameter of the receiving platform to prevent qualified seeds from being collected between inferior seeds.

[0010] Through the above technical solution, inferior seeds of different levels can be classified and stored to prevent inferior seeds of different levels from being mixed among qualified seeds and affecting the screening quality.

[0011] The storage part and the temporary storage part are respectively provided with a first push plate and a second push plate, which are connected and fixed by a connecting rod on the outer side of the push plate, and are used to push the collected seeds to promote feeding.

[0012] Through the above technical solution, the seeds can be directly pushed to the feeding port, realizing the function of convenient feeding.

[0013] The segmented positioning cylinders are distributed inside along the axis of the shaft frame, and the ends are flush with each other to form a positioning groove. A ring grid is arranged inside the upper end of the positioning groove to transmit wind force.

[0014] Through the above technical solution, the ring grid frame is used to block seeds and prevent them from being scattered inside the shaft frame.

[0015] The support rod on the upper end of the paddle is installed on the rotating rod through a positioning groove. The upper end of the rotating rod is provided with a positioning seat with a protruding circular block rotatably installed inside the top seat.

[0016] Through the above technical solution, the upper end of the rotating rod is positioned using the positioning seat, which can prevent it from swinging during rotation, thereby ensuring the stability of the screening operation.

[0017] The upper end of the driving motor is provided with a convex shaft for mounting rotary blades, which is used to apply wind force to perform blowing and screening operations. The outer ring frame with a stepped structure is located inside the storage groove near the upper end, and is used to transmit the rotational power of the driving motor to the rotary rod.

[0018] Through the above technical solution, the inner side of the lower end of the outer ring frame is a protruding tooth-shaped structure.

[0019] An inner ring frame is provided on the outer side of the convex shaft, which meshes with the inner side of the lower end of the outer ring frame to slow down the rotation speed of the rotating rod. Fixed rods are respectively provided on the outer side of the rotating rod and the convex shaft to connect the outer ring frame and the inner ring frame.

[0020] Through the above technical solution, the cam shaft is divided into two layers, the upper layer is equipped with a fixed rod, and the lower end is equipped with a rotary blade.

[0021] An inner ring seat is provided inside the receiving groove for rotatably mounting a protruding ring body mechanism on the outer side of the outer ring frame.

[0022] A method for fine screening and classification of seed breeding particles, using the above-mentioned screening machine, and its specific use method is as follows:

[0023] S1: First, use the top seat to evenly disperse the applied seeds around the circumference to prevent them from piling up in one place, so that inferior seeds are exposed to the outside;

[0024] S2: Using the driving motor and the convex shaft to apply wind force, the seeds are sprayed out through the ring grid, driving the inferior seeds to fly outwards on the way down, and are received in the storage part by the receiving device;

[0025] S3: The seeds falling on the surface of the conical screening net are classified and screened according to the size of the mesh;

[0026] S4: utilizing the meshing of the inner ring frame and the outer ring frame and the fixed connection of the fixed rod to reduce the speed of the rotational power of the driving motor and transmit it to the rotating rod, so as to drag the paddle to rotate and dredge the mesh of the conical screening net to prevent blockage;

[0027] S5: The prying plate drives the first push plate and the second push plate to rotate through the connecting rod, so as to gather the seeds in the storage part and the temporary storage part respectively for easy discharge and use.

[0028] Beneficial effects of the present invention:

[0029] When screening seeds, the top seat is used to evenly disperse them in the circumferential direction. During the falling process, the wind force applied by the driving motor can directly blow out the inferior seeds. Compared with the existing screening method, it can effectively avoid the situation where the inferior seeds are accumulated inside the qualified seeds and cannot be directly separated. At the same time, it also prevents the qualified seeds from being carried away and separated, causing cost waste;

[0030] Since inferior seeds are blown out by the air during their fall, the receiving table can directly receive and store them in the storage unit. After this arrangement, the inferior seeds can be quickly collected to avoid falling between qualified seeds and affecting screening. At the same time, the collection of inferior seeds is also convenient for subsequent cleaning and use.

[0031] When the driving motor rotates and applies wind force, the engagement of the inner ring frame and the outer ring frame can drive the rotating rod to rotate slowly, and then drag the paddle plate, the first push plate and the second push plate to rotate. On the one hand, it can scrape the surface of the conical screening net to prevent some seeds from getting stuck in the mesh holes, and on the other hand, it can push the collected planting boxes to gather in one place to automatically form a material collection, which is convenient for subsequent transportation and other operations.
