Description

Technical Field

[0001] This utility model relates to the field of agricultural and grain machinery technology, specifically to a tracked pulse dust removal grain unloader. Background Technology

[0002] A grain unloader is a type of machinery used for agricultural grain processing. It is mainly used for collecting, cleaning, conveying, and stacking grain after harvest. Its core function is to achieve efficient processing through mechanical linkage. The equipment can be divided into three types according to the usage scenario: towed (tractor-tethered, suitable for large-area farmland), self-propelled (with its own power system, highly mobile), and stationary (installed in warehouses for pre-cleaning). During operation, the front rotating rake teeth or scraper gather the scattered grains, and the middle conveyor belt or screw conveyor transports them to the rear. Grain unloaders are widely used in the post-harvest processing of field crops such as wheat, rice, and corn, as well as in the pre-processing of grains entering warehouses and seed processing in warehousing and logistics.

[0003] Currently, grain unloaders often generate a lot of dust during use, which deteriorates the working environment inside the grain warehouse. Moreover, after the grain is transferred by the grain unloader, there are still a lot of small particulate impurities (dust, grain dust, etc.) and damaged grain (shriveled grain, broken grain, etc.) in the grain, which further reduces the cleanliness of the grain. Utility Model Content

[0004] To address the problem of excessive impurities in grain after grain transfer using a grain unloader, as mentioned in the background art, the purpose of this utility model is to provide a tracked pulse dust removal grain unloader.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tracked pulse dust removal grain unloader, including a support frame, on which a second material conveying trough is installed, a material conveying belt is installed inside the second material conveying trough, and a discharge hopper is installed at one end of the second material conveying trough;

[0006] A transfer bin is rotatably mounted on the support frame, and a first conveying trough is installed inside the transfer bin. A scraping trough is installed at one end of the first conveying trough. A rotating ring is provided inside the transfer bin, and the upper end of the first conveying trough is correspondingly arranged with the rotating ring.

[0007] A chain is installed in the first feeding trough and the feeding trough, and several feeding plates are installed on the chain. A screening box is installed on one side of the transfer bin, and a first drive motor is installed in the screening box. The first drive motor drives the chain through a belt and a pulley.

[0008] A dust collector is installed on the screening box. The discharge hopper is connected to the dust collector via a second connecting pipe. The material feeding chute is connected to the dust collector via a first connecting pipe.

[0009] Preferably, a track is installed on the lower side of the bracket, a second drive motor is installed on the bracket, the second drive motor drives the track, and a pusher shovel is installed on one side of the bracket.

[0010] Preferably, a gathering plate is installed inside the feeding trough, and the gathering plate is configured to cooperate with the chain.

[0011] Preferably, the transfer bin is equipped with a servo motor, which is driven by a gear set to connect to the rotating ring.

[0012] Preferably, a dust removal fan is installed on one side of the dust removal box, and a pump station is installed on the transfer hopper, with the pump station and dust removal box being configured together.

[0013] Preferably, the screening box is connected to the dust collection box, a connecting seat is sleeved and fixed on the first drive motor, a screening plate is inserted into the screening box, and a buffer spring is installed between the connecting seat and the screening plate.

[0014] Preferably, the screening box has a defective grain outlet and a small particle impurity outlet, with the defective grain outlet located above the screening plate and the small particle impurity outlet located below the screening plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. During operation, this utility model utilizes a negative pressure pump station to create a continuous negative pressure environment within the dust collection box. Utilizing the principle of airflow adsorption, lightweight impurities (such as dust and debris) from the material handling chute and discharge hopper areas are simultaneously drawn into the dust collection box via parallel-connected first and second pipes. Dust removal is achieved throughout the entire grain transport process. Through directional airflow guidance and the synergistic effect of the filter bags within the dust collection box, dust generated by the high-speed transfer of materials during traditional grain handling operations is effectively suppressed. This significantly improves the air quality of the working environment while ensuring grain transfer efficiency, meeting the technical requirements for clean and intelligent operations in modern grain depots.

[0017] 2. When this utility model is in operation, after the impurity-laden airflow enters the dust collection box, the first stage is achieved by multi-layer gradient dust collection bags for efficient interception. Impurities cannot penetrate the filter cloth and settle on the surface of the vibrating screening plate. The first drive unit transmits to the screening plate through the buffer spring, and uses the difference in motion of materials with different particle sizes to achieve the sorting of impurities. Dust particles with a particle size <2mm penetrate the screen holes under the action of vibration and are discharged through the small particle impurity outlet at the bottom. Damaged grains remain above the screening plate and are discharged through the defective grain outlet. The sorted damaged grains can be used as feed raw materials to achieve resource utilization, which significantly improves the precision of material sorting and the continuity of operation.

Detailed Implementation

[0026] 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.

[0027] like Figure 1 - Figure 7 As shown, the tracked pulse dust removal grain unloader provided in this embodiment includes a support 101, a track 103 is installed on the lower side of the support 101, a second drive motor 115 is installed on the support 101, the second drive motor 115 drives the track 103, and a pusher shovel 102 is installed on one side of the support 101 through a hydraulic rod, and the lifting and lowering of the pusher shovel 102 is controlled by the extension and retraction of the hydraulic rod.

[0028] A second material conveying trough 110 is installed on the bracket 101. A material conveying belt 111 is installed inside the second material conveying trough 110. A discharge hopper 112 is installed at one end of the second material conveying trough 110. Several herringbone-shaped grooves are provided on the material conveying belt 111.

[0029] A transfer hopper 104 is rotatably mounted on the upper side of the bracket 101 via a rotating ring 116. A servo motor 114 is mounted on the transfer hopper 104. The servo motor 114 is connected to the rotating ring 116 via a gear set, causing the rotating ring 116 to rotate, which in turn causes the transfer hopper 104 to rotate. A first conveying trough 105 is hinged to the transfer hopper 104 (see reference). Figure 3 The transfer bin 104 and the first conveying trough 105 are also equipped with two opposing hydraulic rods, which control the lifting and lowering of one end of the first conveying trough 105.

[0030] A scraper trough 106 is installed at one end of the first feeding trough 105. Several rotating shafts are installed in the scraper trough 106 and the first feeding trough 105. A gear is installed on each rotating shaft. A chain 107 is installed on the gear. Several scraper plates 108 are installed on the chain 107. Two spiral gathering plates 109 are installed on the rotating shaft of the scraper trough 106. The two gathering plates 109 are located on opposite sides of the chain 107. When the rotating shaft rotates, the gathering plates 109 push the grain toward the scraper plates 108, so that the grain gathers toward the scraper plates 108.

[0031] A screening box 206 is installed on one side of the transfer bin 104. A first drive motor 113 is installed inside the screening box 206. The first drive motor 113 drives the chain 107 through a belt and pulley.

[0032] A dust collector 201 is installed on the screening box 206. A dust collector fan 202 is installed on one side of the dust collector 201. A pump station 203 is installed on the transfer hopper 104. The pump station 203 is configured to cooperate with the dust collector 201. The pump station 203 includes pneumatic and hydraulic functions. The screening box 206 is connected to the dust collector 201. A connecting seat 301 is sleeved and fixed on the first drive motor 113. A screening plate 302 is inserted into the screening box 206. A buffer spring 303 is installed between the connecting seat 301 and the screening plate 302.

[0033] Specifically, when the first drive motor 113 is in use, the vibration generated by the first drive motor 113 is transmitted to the screening plate 302 through the connecting seat 301 and the buffer spring 303, which can improve the screening effect and efficiency of the screening plate 302.

[0034] The screening box 206 has a defective grain outlet 304 and a small particle impurity outlet 305. The defective grain outlet 304 is located above the screening plate 302, and the small particle impurity outlet 305 is located below the screening plate 302. The discharge hopper 112 is connected to the dust collector 201 through a second connecting pipe 205, and the chute 106 is connected to the dust collector 201 through a first connecting pipe 204.

[0035] The dust collector 201 removes dust using pulsed gas and its internal filter bags. During use, a negative pressure is generated inside the dust collector 201, causing light impurities in the chute 106 to enter the dust collector 201 through the first connecting pipe 204. Light impurities in the grain discharged from the hopper 112 enter the dust collector 201 through the second connecting pipe 205. Then, the negative pressure stops, and the light impurities fall onto the screening plate 302. The vibration generated by the first drive motor 113 during operation is transmitted to the screening plate 302 through the buffer spring 303, causing the screening plate 302 to vibrate. This causes small particles of light impurities to fall off the screening plate 302. Finally, the small particles of light impurities are discharged through the small particle discharge port 305, and the damaged grains in the light impurities are discharged through the damaged grain discharge port 304. Through the above-mentioned negative pressure impurity removal method, the impurity content in the grain after being removed by the grain remover can be further reduced. Moreover, this application can separate the impurities obtained by negative pressure impurity removal, separating the damaged grains from the small particles of impurities.
