TECHNICAL FIELD

[0002] As a kind of high-efficiency sorting equipment, caterpillar belt color sorter is widely used in the field of agricultural product processing, ore sorting, recycling of renewable resources and screening of traditional Chinese medicinal materials. For irregularly shaped materials such as peanut kernels, almonds and glass, multi-stage sorting is usually required by using double-layer caterpillar belt machine to improve the sorting rate. However, in the first sorting process, a large amount of chaff and dust impurities are often mixed in the rejected materials. If these impurities directly enter the second sorting process, they are easy to adhere to the surface of the materials or suspended in the sorting area, resulting in blurred camera imaging and reduced recognition accuracy, which further affects the second color selection effect.
[0003] In the prior art, double-layer caterpillar belt machine relies on devices such as vibrating screen structure, dust hood or spraying system for dust removal. Although these devices can partially alleviate the impurity problem, they still have significant defects. First, the vibrating screen structure and the spraying system need to be equipped with additional power units and auxiliary equipment, which increases the overall cost and occupies a large space, limiting the application of the equipment in compact scenarios. Second, the adaptability of the existing dust removal devices is poor, and it is difficult to flexibly adjust the dust removal parameters according to different material characteristics such as particle size, density and humidity, resulting in large fluctuations in dust removal efficiency. In addition, the existing technology lacks efficient dust removal means after the first sorting, and the rejected materials cannot be quickly cleaned of the chaff and dust raised before entering the second sorting, and the residual impurities continue to interfere with the sorting process, which becomes a key bottleneck restricting the improvement of color selection accuracy. Therefore, how to efficiently, flexibly and low-costly remove dust before the second selection of double-layer caterpillar belt machine is a technical problem to be solved. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.
[0026] The caterpillar color sorter is widely used in the fields of agricultural product processing, ore sorting and renewable resource recycling as a high-efficiency sorting equipment. For irregularly shaped materials such as peanut kernels and glass, the double-layer caterpillar machine can improve the sorting purity through multi-stage sorting. However, a large amount of broken skin and dust impurities are often mixed in the poor materials after the first sorting. If these impurities directly enter the second sorting link, they are easy to adhere to the surface of the materials or suspend in the sorting area, resulting in blurred camera imaging and reduced recognition accuracy, which seriously restricts the color sorting effect. In the existing technology, the double-layer caterpillar machine often relies on a vibrating screen, a dust suction hood or a spraying system for dust removal. However, these devices need to be equipped with additional power units and auxiliary equipment, which not only has high cost but also occupies a large space, limiting the application of the equipment in compact scenes. In addition, the existing dust removal devices have poor adaptability and are difficult to flexibly adjust the dust removal parameters according to the particle size, density and other characteristics of different materials, resulting in significant fluctuations in dust removal efficiency. Especially after the first sorting, there is a lack of effective means to quickly remove dust, and the residual impurities continuously interfere with the second sorting process, becoming a key bottleneck to improve the color sorting accuracy.
[0027] As shown in Figure 1 , it is a dust removal device for a double-layer caterpillar color sorter. The dust removal device includes an air suction cavity 2-1, a poor material discharge hopper 3-1 and a blowing cavity 4-1. The fixed points of the dust removal device are on both sides of the poor material discharge hopper 3-1 of the double-layer caterpillar machine 1-1. The air suction cavity 2-1 is arranged above the poor material discharge hopper 3-1, and the blowing cavity 4-1 is arranged below the poor material discharge hopper 3-1. The outer shell of the air suction cavity 2-1 is provided with an air suction cavity cover plate 2-2, and the inside is provided with an air suction cavity air volume adjusting plate 2-3. The outer shell of the blowing cavity 4-1 is provided with a blowing cavity cover plate 4-2, and the inside is provided with a blowing cavity air volume adjusting plate 4-3. Due to the small space, the blowing cavity 4-1 has a large volume, and there is a blowing fan 4-5 on one side of the blowing cavity, so the structure is set as an upper suction and lower blowing structure.
[0028] As shown in Figure 2 , it is a structure diagram of the air suction cavity 2-1. The air suction cavity 2-1 is fixed above the poor material discharge hopper 3-1 through an air suction cavity side edge support 2-4. Both sides of the air suction cavity 2-1 are provided with dust suction pipes 2-5. The air suction cavity cover plate 2-2 is fixed on the air suction cavity 2-1 by bolts and is a plurality of rectangular structures installed respectively. The air suction cavity air volume adjusting plate 2-3 is connected to the inner wall of the air suction cavity 2-1 through an upper and lower sliding waist hole and a threaded connection.
[0029] As shown in Figure 3As shown, it is the structure diagram of the blowing cavity 4-1. The blowing cavity 4-1 is fixed below the defective material discharge hopper 3-1 through the suction cavity side support 2-4, one side of the blowing cavity 4-1 is provided with a blowing fan 4-5, the blowing cavity cover plate 4-2 is fixed on the blowing cavity 4-1 through bolts, it is a plurality of rectangular structures respectively installed, the blowing cavity air volume adjusting plate 4-3 is connected on the inner wall of the blowing cavity 4-1 through the waist hole and the screw thread of the up and down sliding, the suction cavity 2-1 and the blowing cavity 4-1 are arranged opposite, the wind direction of the defective material discharge hopper 3-1 is from bottom to top, which is perpendicular to the movement trajectory of the defective material in the defective material discharge hopper 3-1.
[0030] In the installation and use process of the device of the embodiment, the suction cavity 2-1 and the blowing cavity 4-1 are fixed on both sides of the opening of the defective material discharge hopper 3-1 of the double-layer crawler belt machine 1-1 through the suction cavity support 2-4 and the blowing cavity support 4-3. The bolts for fixing the suction cavity cover plate 2-2 are removed, the suction cavity air volume adjusting plate 2-3 is loosened, the position of the suction cavity air volume adjusting plate 2-3 is adjusted through the up and down sliding of the waist hole on the suction cavity air volume adjusting plate 2-3, so as to adjust the size of the suction airflow velocity. The bolts for fixing the blowing cavity cover plate 4-2 are removed, the blowing cavity air volume adjusting plate 4-3 is loosened, the position of the blowing cavity air volume adjusting plate 4-3 is adjusted through the up and down sliding of the waist hole on the blowing cavity air volume adjusting plate 4-3, so as to adjust the size of the blowing airflow velocity.
[0031] The device of the embodiment accelerates the gas flow at the defective material discharge hopper 3-1 through the mode of downward blowing and upward suction, so as to achieve the purpose of quickly removing dust, and further ensure the effect of secondary color selection. In use, the selected material is conveyed to the feeding end of the double-layer crawler belt machine, and then is accelerated to the upper layer sorting box assembly for primary sorting after sliding down to the upper layer crawler belt. After the primary sorting, the qualified material is taken out from the good product outlet, and the unqualified material enters the defective product port and then enters the lower layer crawler belt for sorting. During the primary sorting, the blowing nozzle blows the gas to remove the defective material, which causes a large amount of broken skin and dust impurities to be raised in the defective product port. The dust removal device installed on both sides of the defective material discharge hopper 3-1 removes the dust, that is, the blowing cavity 4-1 on the lower side blows the dust into the upper suction cavity 2-1, and the gas is continuously circulated and quickly flows, so as to finally take away the dust. On this basis, the unqualified material after the primary sorting enters the lower layer crawler belt for secondary sorting. After the sorting of the lower layer crawler belt, the qualified material is taken out from the good product outlet, and the unqualified material is taken out from the defective product outlet.
[0032] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
