Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grain cleaning, more particularly to a combined cleaning machine. BACKGROUND

[0002] In agricultural production, grain cleaning is an important link to ensure the quality of grain. However, the traditional grain cleaning mechanism generally has the problems of low cleaning efficiency and poor effect. This is mainly due to the shortcomings and defects in the structural design. The structure of the prior art document CN103447238A is too complex, and it is inconvenient to transport in actual transportation process.

[0003] The performance of its cleaning device still needs to be improved. The indicators for measuring the cleaning performance mainly include the impurity content of the grain and the cleaning loss rate, and the existing cleaning device often fails to meet the ideal index requirements.

[0004] In order to solve the above problems, the technical personnel has carried on the in-depth research to the cleaning device. A variety of improvement schemes are proposed. For example, some researches change the structure of the screen body, such as adopting a wave screen type screen piece combination, to enhance the vortex effect of the screen surface, thereby improving the separation effect of the grain and the impurities. However, although these improvement schemes improve the cleaning efficiency and quality to some extent, there are still some limitations. Therefore, it is necessary to continue to strengthen the related research and product development, so as to further improve the performance of the grain cleaning machine and meet the urgent needs of agricultural production for high-efficiency and high-quality cleaning operation.

[0005] Against this background, the present application proposes a new type of grain cleaning mechanism, which aims to solve the problems of low efficiency and poor effect existing in the existing grain cleaning mechanism through innovative structural design and optimized working principle. CONTENT OF THE INVENTION

[0006] Based on the above problems, the present application proposes a combined cleaning machine to solve the technical problems of low efficiency and poor effect existing in the existing grain cleaning machine.

[0007] To solve the above technical problems, the technical scheme adopted by the present application is:

[0008] A combined cleaning machine, comprising a rack, an elevator installed on the rack, a negative pressure air screen for removing dust installed on the rack, a spiral dust collector communicated with the negative pressure air screen, a vertical air screen for removing light impurities communicated with the spiral dust collector, and an exhaust pipe communicated with the spiral dust collector, a stone removal structure is installed below the negative pressure air screen, a cover is arranged between the negative pressure air screen and the stone removal structure, and a screening box is arranged below the stone removal structure.

[0009] In one specific implementation, the stone removing structure comprises a sieve plate and an angle adjusting structure for adjusting the sieve plate, the sieve plate is arranged obliquely, and the sieve plate is lower near one end of the spiral dust remover.

[0010] In one specific implementation, the air exhaust pipe is provided with an air volume adjusting handle.

[0011] In one specific implementation, the screening box is provided with at least one stage of sieve bodies, and the outer wall of the screening box is provided with a vibration motor.

[0012] In one specific implementation, the screening box is provided with a grain outlet box, and the grain outlet box is communicated with the screening box.

[0013] In one specific implementation, the bottom of the spiral dust remover is provided with an air damper and an ash receiving hopper.

[0014] The positive effects of the utility model are as follows:

[0015] The negative pressure air screen effectively removes light impurities such as dust in the grain by generating negative pressure, and the spiral dust remover further separates the impurities in the air, and the combination makes the removal of dust and light impurities more efficient.

[0016] The stone removing structure removes the heavy impurities such as stones by using the difference in specific gravity between the grain and the heavy impurities through the obliquely arranged sieve plate. The multi-stage sieve bodies in the screening box further grade and screen the grain, thereby improving the accuracy and efficiency of the cleaning. The shell arranged between the negative pressure air screen and the stone removing structure helps to form a relatively closed working environment, reduces the flying and diffusion of impurities in the cleaning process, and thereby improves the cleaning effect.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example

[0024] like Figs. 1-2 As shown, a combined cleaning machine includes a frame 1. The frame 1 serves as the support structure for the entire cleaning machine, ensuring the stability and durability of the equipment and providing a stable installation platform for other components, thus guaranteeing the overall stability and reliability of the equipment during operation.

[0025] The elevator 2, mounted on the frame 1, is equipped with a two-stage reduction gear to reduce the breakage rate. A negative pressure air screen 3, also mounted on the frame 1, effectively removes dust and fine impurities from the material using the principle of negative pressure. This improves the cleanliness of the material and provides better raw material quality for subsequent processing.

[0026] The negative pressure air screen 3 is connected to a spiral dust collector 4, a vertical air screen 5 connected to the spiral dust collector 4 for cleaning and removing impurities, and an exhaust pipe 6 connected to the spiral dust collector 4. The spiral dust collector 4 has a shut-off valve 14 and a dust collection hopper 15 at its bottom. The vertical air screen 5 is used to further remove impurities from the material, improving its purity. A fan is connected to the exhaust pipe 6. The exhaust pipe and fan work together to discharge the clean air processed by the spiral dust collector 4, ensuring the normal operation of the equipment. An airflow adjustment handle 11 is installed on the exhaust pipe 6 to adjust the airflow. The spiral dust collector 4 is connected to the negative pressure air screen 3, enabling further collection and processing of dust and impurities generated by the negative pressure air screen 3.

[0027] A stone removal structure 7 is arranged below the negative pressure air screen 3, which includes a screen plate 10 and an angle adjusting structure for adjusting the screen plate 10. The screen plate 10 is arranged obliquely, and the end of the screen plate 10 close to the spiral dust collector 4 is lower. The stones and other heavy objects in the material are separated out by the gravity of the material and the vibration of the screen plate 10. A cover 8 is arranged between the negative pressure air screen 3 and the stone removal structure 7, which plays a protective and isolating role. It prevents the material from splashing and scattering during the processing, and improves the safety and cleanliness of the equipment

[0028] A screening box 9 is arranged below the stone removal structure 7, and at least one level of screen bodies is arranged in the screening box 9. Each level of screen bodies corresponds to a different discharge port. A vibrating motor 12 is arranged on the outer wall of the screening box 9.

[0029] An out-feed box 13 is arranged on the screening box 9, which communicates with the screening box 9. Multiple levels of screen bodies are arranged in the screening box 9, and each level of screen bodies corresponds to a different discharge port. The material can be classified and screened according to different particle sizes and properties. Through the screening of multiple levels of screen bodies, the material can be classified according to different particle sizes and properties, providing more selectivity and flexibility for subsequent processing. The vibrating motor 12 is mounted on the outer wall of the screening box 9 through a rotating structure, providing vibration power for the screening box 9.
