Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of impurity removing device, concretely is grain planting impurity removing device. BACKGROUND

[0002] Impurity removing device removes impurities in materials by physical method. For example, grain impurity removing machine removes impurities in grain by screen filter and fan suction, ensuring the quality and purity of grain. In industrial application, impurity removing device is widely used in various material processing processes, such as chemical industry, metallurgy, food processing and other fields, to ensure the quality and purity of products.

[0003] According to the patent, a grain impurity removing device for agricultural planting is disclosed (publication number: CN221387408U), which comprises a main body, a feed inlet arranged at the upper end of the main body, a controller arranged at the front end of the main body, a screening mechanism arranged inside the main body, a flow guide plate arranged on one side of the main body, and a discharge port arranged at the rear end of the flow guide plate. By starting the vibration motor, the vibration rod starts to vibrate, and the conduction plate conducts the vibration. At this time, the first screening net and the second screening net start to vibrate. When the grain passes through the first screening net, the first screening net can screen out the larger impurities mixed in the grain and guide them into the pull-out cabinet in the collection box through the first guide plate. When the grain passes through the second screening net, the second screening net can screen out the smaller impurities mixed in the grain. The screened grain is guided to the discharge port through the second guide plate.

[0004] Although the above-mentioned patent sets up a screening mechanism and a vibration motor, and drives the vibration rod to vibrate through the vibration motor to screen out the impurities in the grain, filters the grain through the first screening net, and avoids mixing impurities with grain, but the impurity removing process of grain often needs to screen different grains and screen out impurities in the grain. When screening grains of different particle sizes, the first screening net needs to be disassembled and replaced. This operation is relatively cumbersome, and the normal operation of the machine also needs to be suspended, which is not conducive to improving the impurity removing efficiency of grain.

[0005] Therefore, the utility model provides a grain planting impurity removing device to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0017] (Three) beneficial effects

[0018] By incorporating a sieving component, impurities in the grain can be screened out, preventing contamination and ensuring proper packaging quality. A longitudinally sliding sieve plate continuously vibrates, separating impurities that fall onto it. Larger particles slide through the inclined sieve plate into the impurity box.

This adjustment changes the diameter of the filter balls, thus altering the particle size at which the grains fall. This simple structure allows for adjustment of the sieving particle size based on the grain type without stopping the screening process, enhancing the device's versatility.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The utility model provides grain planting removes the device, such as Figures 1-6 As shown, the grain planting removes the device, including box 1, the upper top of box 1 is equipped with the feeding port 2, the inside of box 1 is provided with the impurity removal subassembly;

[0029] Impurity removal subassembly includes the chute 3 of opening in the inside wall of box 1, the inner wall sliding connection of chute 3 has the sieve plate 4, the end of sieve plate 4 is equipped with a plurality of filter holes 5, the inside of sieve plate 4 is equipped with a plurality of round grooves 6, the inner wall rotation of round groove 6 is connected with a plurality of rotating rods 7, the end of rotating rod 7 is located in filter hole 5 and is fixedly connected with filter ball 8, the upper top of sieve plate 4 is fixedly connected with a plurality of baffle strips 9, and the end of baffle strip 9 is equipped with a plurality of round holes.

[0030] The outer side wall of box 1 is fixedly connected with support plate 10, the upper top of support plate 10 is fixedly connected with drive motor 11, the side wall of box 1 is fixedly connected with rotating sleeve 12 at the output end of drive motor 11, and the outer wall of the output shaft of drive motor 11 is fixedly connected with cam 13.

[0031] The side wall of box 1 is fixedly connected with a plurality of shock absorbing sleeves 14, the inner wall of shock absorbing sleeve 14 is fixedly connected with elastic strip 15, the end of elastic strip 15 is fixedly connected with rotating sleeve 16, rotating sleeve 16 is rotationally connected with knob lever 17, and the end of knob lever 17 is fixedly connected with rotating rod 7.

[0032] The inner wall of box 1 is rotationally connected with stirring rod 18, the end of stirring rod 18 is fixedly connected with driven wheel 19, the outer wall of the output shaft of drive motor 11 is fixedly connected with driving wheel 20, and the outer wall of driving wheel 20 and driven wheel 19 is sleeved with synchronous belt 21.

[0033] Specifically, by the impurity removal assembly, the impurities in the grain can be screened through the screen plate 4 during the grain screening process, so as to avoid the mixing of impurities with the grain and affect the packaging quality of the grain. When the grain falls from the feeding port 2 at the top end of the box body 1, the driving motor 11 is driven to rotate, the synchronous belt 21 is driven to rotate by the driving motor 11, and the stirring rod 18 on the inner wall of the driven wheel 19 is driven to rotate. The falling grain is continuously hit, which can avoid the phenomenon of grain adhesion. The grain particles are separated by hitting, so as to avoid the clogging of the screen plate 4 by the adhered grain. When the driving motor 11 rotates, the cam 13 connected to the output end of the driving motor 11 continuously abuts against the screen plate 4, so that the screen plate 4 continuously slides longitudinally in the chute 3, and the grain on the screen plate 4 is continuously vibrated, so that the impurities in the grain are separated from the grain.

Since the blocking strip 9 is provided, the grain can be screened by the filter hole 5, and the impurities will not fall into the impurity box 24. The impurities will fall into the impurity box 24 due to vibration. The device has simple structure and high practicability, can change the falling diameter of the screen plate 4 without affecting the screening efficiency, can adapt to the screening of grains and impurities of different particle sizes, and can ensure that the rotating knob rod 17 moves longitudinally in the screen plate 4.

[0035] The impurity box 24 for receiving impurities is slidingly connected to the side wall of the box body 1. The receiving box 25 is slidingly connected to the outer wall of the box body 1.

[0036] Specifically, the fan 22 on the side wall of the box body 1 works to blow the falling grain. The high-speed airflow blows the dust in the grain, and then blows the impurities into the cleaning box 23. The filter screen at the end of the cleaning box 23 can adsorb the dust, so as to avoid the dust floating in the box body 1 and affecting the screening quality of the grain. When there are many impurities, the impurity box 24 is manually pulled to pour the impurities in the impurity box 24, so as to keep the impurity box 24 clean. When the screened grain increases, the receiving box 25 receives the grain for the next processing of the grain.

[0037] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
