Description

Technical Field

[0001] The utility model relates to the technical field of grain storage and transportation, in particular to a grain scraper for grain stacking. Background Art

[0002] In modern agricultural production and grain storage and transportation systems, efficient grain loading and unloading operations are one of the key links to ensure food safety, reduce losses, and improve economic benefits. With the advancement of science and technology and the continuous improvement of mechanization, various modern grain loading and unloading equipment are widely used in grain warehouses, processing plants, and transportation terminals to achieve fast, clean, and low-loss grain handling processes. However, in the actual operation process, there are still some details that need to be continuously optimized and solved, including the loss control problem when unloading grain.

[0003] Grain unloading pits are common facilities for receiving and temporarily storing grain. Their original design was to facilitate large grain transport vehicles to directly unload grain into the pits, and then transfer the grain to warehouses or other processing facilities through mechanical equipment such as conveyor belts and elevators. In theory, this process can achieve continuous and efficient operation, but in actual application, due to many reasons such as equipment matching, operating technology, and environmental factors, it is often difficult to completely avoid grain from scattering to the ground outside the grain unloading pit during the unloading process.

[0004] If these accidentally scattered grains are not cleaned up in time and reintegrated into the normal processing process, they will not only cause a waste of grain resources, but may also cause health and safety problems, such as attracting pests and mildew, affecting grain quality and storage safety. Therefore, despite the support of advanced mechanized equipment for the main loading and unloading processes, the manual cleaning and recollection of these scattered grains is still indispensable, becoming an additional manpower demand point in grain processing operations.

[0005] In this scenario, workers need to clean and collect the scattered grain around the grain unloading pit regularly or irregularly, and use special shovels and other tools to return it to the grain unloading pit for subsequent mechanized processing. Although this process seems simple, it actually increases the labor intensity of workers and occupies time and energy that could be used for other production activities. In the long run, it is not conducive to work efficiency and cost control.

[0006] Although conventional grain scrapers on the market can improve collection efficiency to a certain extent, they still face several key problems and need to be further optimized to meet the needs of collecting scattered grain around the grain unloading pit. Since the ground around the grain unloading pit is relatively flat and hard, it is often difficult for ordinary grain scrapers to completely remove all grain particles on the ground. The remaining grain not only wastes resources, but also increases the burden of subsequent cleaning work, which is not conducive to the return of grain particles to the warehouse. Utility Model Content

The rear support member adopts a hydraulic cylinder, and the upper and lower ends of the hydraulic cylinder are respectively hinged to the grain transport passage and the traveling mechanism.

[0010] Furthermore, a wear-resistant layer is provided on the outer side of the grain shoveling part arranged at the lower side of the volute cover, and a slope is provided on the outer end of the wear-resistant layer.

[0011] Furthermore, a guide plate is provided in the grain outlet, and the guide plate includes an inclined plate and a vertical plate parallel to the grain outlet, wherein the inclined plate is fixed above the vertical plate, and the transported grain collides with the inclined plate and rebounds, and flows out from the lower grain channel separated by the vertical plate, and the dust outlet is arranged on both sides of the lower grain channel separated by the vertical plate.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below.

[0019] Embodiment 1: In view of the particularity of the scattered grain piles around the grain unloading pit, the utility model provides a grain-pile scraper, which can effectively collect the scattered grain piles around the grain unloading pit into the grain unloading pit, and at the same time, the dust removal fan 6 is used to prevent excessive dust around the grain unloading pit from entering the grain unloading pit during the collection process. Figure 1 As shown, the grain-pile raking machine includes a volute cover 1, a grain transport channel 2, a driving device 3 and a walking mechanism 7, wherein the volute cover 1 and the grain transport channel 2 are welded and made of metal plates, wherein the volute cover 1 includes a semicircular cover shell, a baffle plate extends on the upper side of the cover shell to prevent grain from splashing during collection, and a grain shoveling plate parallel to the ground is provided on the lower side of the cover shell, and the front end of the grain shoveling plate is provided as an inclined surface. Generally, the ground around the grain unloading pit needs to be leveled, so when in use, the front end of the grain shoveling plate can fit the ground, so that the grain can be shoveled into the volute cover 1 through the inclined surface, which is convenient for subsequent collection.

[0020] The grain transport channel 2 is a square pipe, which is welded and fixed to the middle part of the rear side of the volute cover 1. The volute cover 1 is connected to the interior of the grain transport channel 2, and the grain collected in the volute cover 1 is transferred and transported through the grain transport channel 2.

[0021] A walking mechanism 7 is installed below the grain transport passage 2. The walking mechanism 7 can be a three-wheel, four-wheel or crawler structure walking mechanism 7. In this embodiment, a four-wheel trolley is used as the walking mechanism 7 of the grain picker. The four-wheel trolley has better stability and relatively low cost. A supporting device is installed on the frame of the four-wheel trolley, and the grain transport passage 2 is fixed on the walking mechanism 7 through the supporting device, so that the walking mechanism 7 drives the entire grain picker to move.

[0022] like Figure 2 As shown, a driven shaft 11 is installed transversely through the volute cover 1, and both ends of the driven shaft 11 are fixed by bearing sleeves, and a driven sprocket 12 is installed in the middle of the driven shaft 11. Specifically, the driven sprocket 12 is on the central axis of the entire raking machine and corresponds to the central axis of the grain transport channel 2. At the same time, a left spiral disk 13 and a right spiral disk 14 with opposite spiral directions are installed at both ends of the driven shaft 11. The lengths of the left and right spiral disks are the distances from the side of the volute cover 1 to the side of the adjacent grain transport channel 2. The left and right spiral disks are fixed on the driven shaft 11 and rotate with the driven shaft 11.

[0023] like Figure 2 and Figure 3 As shown, a driving shaft 4 is transversely mounted on the upper end of the grain transport channel 2, one end of which extends outward and is in transmission connection with the driving device 3, and a driving sprocket 41 is fixed in the middle of the driving shaft 4; a chain 21 is wound around the driving sprocket 41 and the driven sprocket 12, and a plurality of grain picking plates 22 are evenly distributed on the chain 21. In this embodiment, the driving device 3 adopts a motor, which is mounted on the grain transport channel 2, and a pulley is mounted on the end of the driving shaft 4 extending outward and the output shaft of the motor, and the driving shaft 4 and the motor are connected through a V-belt transmission.

[0024] The motor drives the driving shaft 4 to rotate, and the active sprocket 41 on the driving shaft 4 drives the driven sprocket 12 in the volute cover 1 to rotate through the chain 21, thereby driving the left spiral disk 13 and the right spiral disk 14 to rotate, and the scattered grains are gathered to the middle. The grain picking plate 22 on the chain 21 moves with the chain 21, and pushes the grain gathered in the middle upward, so that the grain is discharged and collected from the grain outlet 5 at the upper end of the grain transport channel 2.

[0025] During the process of gathering and pushing the grains, dust on the grains will be blown up due to movement and vibration, but the volute cover 1 and the grain transport passage 2 will restrict the dust from drifting, so that the dust can only be discharged from the grain outlet 5 .

[0026] The grain scraper provided by the utility model uses the inclined surface at the front end of the volute cover 1 to enable the machine to scoop up scattered grains on the ground more quickly and more completely when the machine contacts the scattered grains, thereby reducing the loss of grains due to crushing or omissions during the collection process and improving the comprehensive efficiency and integrity of grain collection, which not only reduces the waste of grain resources but also helps to improve the overall operation output.

[0027] Example 2: Figure 3 As shown, the support device used in the raking machine includes a front articulated seat 71 and a rear support member 72, wherein the front articulated seat 71 is installed at the front end of the traveling mechanism 7, and the lower side of the grain transport passage 2 and the front end of the traveling mechanism 7 are connected through the front articulated seat 71, the length of the rear support member 72 is greater than the length of the front articulated seat 71, and the upper and lower ends of the rear support rod are respectively hinged to the lower part of the grain transport passage 2 and the traveling mechanism 7. The rear support member 72 adopts a hydraulic oil cylinder, and the upper and lower ends of the hydraulic oil cylinder are respectively hinged to the grain transport passage 2 and the traveling mechanism 7.

[0028] In addition, a wear-resistant layer 15 is sleeved on the outer side of the grain shoveling plate arranged at the lower side of the volute cover 1, and an inclined surface is arranged on the outer end of the wear-resistant layer 15.

[0029] Since the inclined surface of the grain shoveling plate at the front end of the volute cover 1 needs to contact the ground to shovel grain, its wear speed is relatively fast. Therefore, in this embodiment, a corresponding wear-resistant layer 15 is added to the outer side of the inclined surface, and the wear resistance of the grain shoveling plate is provided by the wear-resistant layer 15. At the same time, the wear-resistant layer 15 is clamped on the front end of the grain shoveling plate in a set manner, and when it is severely worn, it can be replaced to protect the grain shoveling plate.

[0030] The design of the hydraulic cylinder and the front articulated seat 71 allows the hydraulic cylinder to be extended and retracted during use, thereby causing the volute cover 1 and the grain transport channel 2 to rotate around the front articulated seat 71, thereby changing its inclination and allowing the front end of the grain shoveling plate to better fit the ground.

[0031] Embodiment 3: Based on the above embodiment, the grain scraper pushes grain upward through the grain scraper plate 22, and the amount of grain pushed each time is large, and the grain falls fast. Figure 3 As shown, a guide plate 51 is provided in the grain outlet 5, and the guide plate 51 includes an inclined plate and a vertical plate parallel to the grain outlet 5, wherein the inclined plate is fixed above the vertical plate, and the conveyed grain collides with the inclined plate and rebounds, and flows out from the lower grain channel separated by the vertical plate.

[0032] The grains pushed up by the inclined plate rebound can splash and disperse, and at the same time reduce the kinetic energy of the grains carried by the grain-scraping plate 22, so that the grains can be looser and fall down by their own weight, avoiding excessive collision and damage of the grains when they are collected.

[0033] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
