Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, and more specifically, it relates to a device for cleaning impurities in natural forage grasses suitable for high-altitude and cold climate zones. Background Technology

[0002] Due to their unique geographical and climatic conditions, the acquisition and utilization of natural forage resources in high-altitude and cold climate zones has always been a significant technical challenge. Natural forage resources in these regions are mostly wild grass species from natural grasslands, and their yield and nutritional composition are greatly influenced by climate and soil conditions. Studies have shown that different forage species exhibit significant differences in growth performance and nutritional value in high-altitude and cold regions.

[0003] Before using natural forage in livestock farming, it must be screened. Due to the special characteristics of forage in high-altitude and cold regions, existing equipment for screening the mixture of natural forage and impurities (most of which are soil) includes screens and filters. However, these screens are prone to problems such as material jamming, clogging, low sorting efficiency, and high manual labor intensity. In particular, manual handling and transportation of the sorted impurities are required, as well as manual stacking of the sorted natural forage, which seriously affects the sorting efficiency. Moreover, the sorted forage and impurities are not easy to separate and stack, which can easily lead to secondary mixing.

[0004] Therefore, developing a natural forage sorting device suitable for high-altitude and cold climate zones can effectively improve the utilization rate and sorting efficiency of forage, which is of great significance for promoting the sustainable development of animal husbandry in high-altitude and cold regions. Utility Model Content

The baffles are inclined, and the height of the baffles near the cleaning drum is lower than the height of the baffles away from the cleaning drum. The lower end of the baffle is located above the first conveyor. The baffles are used to block impurities screened and discharged from inside the cleaning drum and guide the impurities to the first conveyor.

[0018] In one possible implementation, the frame is connected to square steel support columns and square steel support points. The square steel support columns are vertically arranged and their bottom ends are connected to the frame.

[0029] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Please refer to the following: Figures 1 to 4This invention provides a device for cleaning impurities from natural forage in high-altitude and cold climate zones. The device comprises a frame 1, a cleaning drum 2, a first conveyor 3, and a second conveyor (not shown in the figures, as this is prior art). The frame 1 is inclined, forming an acute angle between its length and the horizontal plane. The cleaning drum 2 is rotatably connected to the frame 1, having circumferential rotational freedom along its axial direction. The axial direction of the cleaning drum 2 is parallel to the length of the frame 1. The cleaning drum 2 is used to screen and filter a mixture of forage and impurities. The first conveyor 3 is connected to the frame 1 and located below the cleaning drum 2. The first conveyor 3 receives impurities screened and discharged from inside the cleaning drum 2 and transports these impurities along the length of the frame 1 to allow them to accumulate. The second conveyor is located to the side of the frame 1 and receives and transports the forage screened from the end of the cleaning drum 2 to allow the forage to accumulate.

[0031] This utility model provides a natural forage impurity cleaning device suitable for high-altitude and cold climate zones. Compared with the prior art, the cleaning drum 2 screens the natural forage during rotation, making it less prone to jamming and clogging. The screened natural forage is transported and piled up by the second conveyor, while the impurities discharged from the screen are received and directionally transported by the first conveyor 3. This solves the technical problems of existing screens easily clogging, high manual labor intensity, and low sorting efficiency when sorting natural forage. It has the technical effects of enabling the cleaning drum 2 to screen natural forage during rotation, making it less prone to clogging, having a high degree of automation, reducing manual labor intensity, and improving sorting efficiency.

[0032] In this embodiment, both the first conveyor 3 and the second conveyor are existing technologies. The first conveyor 3 can transport impurities with one end higher than the other, typically conveying to the lower end. The higher end of the cleaning drum 2 is defined as the feed end, and the other end as the discharge end. In practical use, a trolley or similar device can be used to fill the mixture of natural forage and impurities to be screened into the higher end of the cleaning drum 2. As the cleaning drum 2 rotates, the mixture can be screened and filtered. The screened impurities (such as soil) will leak from the bottom of the cleaning drum 2 and fall onto the first conveyor 3, where they are finally transported, causing the impurities to accumulate. The second conveyor is located on the side of the frame 1, with one end positioned below the lower end of the cleaning drum 2. It can receive the forage discharged from the cleaning drum 2 and transport the screened forage, causing it to accumulate on the side of the frame 1. After the forage and impurities are sorted, they are stored separately for later processing and use.

[0033] In this embodiment, the cleaning drum 2 is a cylindrical body made of screen mesh with multiple filter holes. The diameter of the filter holes is smaller than the length of the forage, etc., to ensure that the forage that meets the requirements cannot fall through the filter holes, while smaller forage or impurities can fall through the filter holes, thereby achieving the screening of natural forage and impurities. For some larger impurities that cannot fall through the filter holes normally, they can be manually removed from the cleaning drum 2 after the machine is stopped.

[0034] The length of the first conveyor 3 is matched with the length of the frame 1, while the length of the second conveyor can be reasonably selected according to the actual situation. Both conveyors are existing technology products. The height of the second conveyor or its bottom end can be connected to a mobile trolley, etc., so that the second conveyor can be moved easily and is convenient to use in different locations, making it flexible to move.

[0035] In some embodiments, please refer to Figures 1 to 4 The natural forage impurity cleaning device suitable for high-altitude and cold climate zones also includes a drum driver 4, which is connected to the cleaning drum 2. The power output of the drum driver 4 is connected to the cleaning drum 2 and used to drive the cleaning drum 2 to rotate circumferentially. The rotation direction and speed of the cleaning drum 2 are controlled by the drum driver 4. During rotation, the cleaning drum 2 will not move laterally along its axis, but can only rotate circumferentially around its axis. The drum driver 4 drives the cleaning drum 2 to rotate, thereby screening the mixture placed inside it. When some filter holes become blocked, other filter holes will be used for screening and filtration, which will not affect the screening effect.

[0036] In some embodiments, please refer to Figures 1 to 4 The frame 1 is connected to multiple rollers, and the cleaning drum 2 rotates circumferentially within the space enclosed by these rollers. The drum driver 4 includes an electrically connected drive motor 41 and a frequency converter 42. The frequency converter 42 controls the operation of the drive motor 41. The frame 1 is rotatably connected to a drive gear 5, and the power output end of the drive motor 41 is connected to the drive gear 5. A ring gear 6 is connected circumferentially along the outer wall of the cleaning drum 2, and the drive gear 5 and the ring gear 6 are mutually driven and meshed. Two or more rollers are spaced apart on each side of the cleaning drum 2, and these rollers provide rolling support for the cleaning drum 2. After the drive motor 41 rotates, it drives the drive gear 5 to rotate, which in turn drives the ring gear 6 to rotate, thus rotating the cleaning drum 2. A set of drum drivers 4 is installed on each side of the cleaning drum 2, operating simultaneously and driving the cleaning drum 2 to rotate, thus maintaining the stability of the cleaning drum 2 during operation. To facilitate the adjustment of the operating parameters of the cleaning drum 2, the operation of the cleaning drum 2 can be indirectly controlled by setting the frequency converter 42 to control the drive motor 41.

[0037] In some embodiments, please refer to Figures 1 to 4 The drum drive 4 is electrically connected to a controller, which includes a wireless communication unit. The wireless communication unit is used to establish real-time communication with external wireless devices to remotely control the operation of the drum drive 4. This controller is a prior art technology that can achieve wireless communication with the outside world through its own wireless communication unit, and thus remotely control the operation of the drive motor 41 through external devices, realizing wireless remote control cleaning operations.

[0038] In some embodiments, please refer to Figures 1 to 4 The natural forage impurity cleaning device suitable for high-altitude and cold climate zones also includes a remote controller. The remote controller is wirelessly connected to a wireless communication unit and has a cleaning control unit suitable for remotely controlling the operation of the drum drive 4. The wireless communication unit is based on existing technology, such as a 4G communication module. The rotation of the drum can be controlled by operating the remote controller, making operation convenient and flexible.

[0039] For remote control of the operation of the first conveyor 3, please refer to some embodiments. Figures 1 to 4 The first conveyor 3 is electrically connected to a controller, and the remote controller has a conveying control unit suitable for remotely controlling the operation of the first conveyor 3. By connecting it to the controller, the operation of the first conveyor 3 can be controlled via the remote controller, thereby enabling operations such as transporting impurities.

[0040] To reduce the outward fall of screened impurities, in some embodiments, please refer to... Figures 1 to 4 The frame 1 is connected to multiple baffles 7, which are located on both sides of the cleaning drum 2 along its axial direction. The baffles 7 are inclined, with the height of the end of the baffle 7 closer to the cleaning drum 2 being lower than the height of the end farther from the cleaning drum 2. The lower end of the baffle 7 is located above the first conveyor 3. The baffles 7 are used to block impurities screened and discharged from inside the cleaning drum 2 and guide the impurities to the first conveyor 3. The baffles 7 can prevent impurities from falling outside the frame 1. The multiple baffles 7 on both sides of the cleaning drum 2 are inclined, which is equivalent to a hopper structure, allowing impurities screened from inside the cleaning drum 2 to fall onto the baffles 7 and be guided onto the first conveyor 3. The baffles 7 are arranged to avoid the drum driver 4 and the first conveyor 3.

[0041] To adjust the height and tilt angle (the angle between the plane of baffle 7 and the horizontal plane) of baffle 7, please refer to the following embodiments: Figures 1 to 4 The frame 1 is connected to square steel support columns 8 and square steel support points 9. The square steel support columns 8 are set vertically and their bottom ends are connected to the frame 1. The square steel support points 9 are connected to the upper end of the square steel support columns 8. The square steel support points 9 are the connection points between the square steel support columns 8 and the baffle 7. The square steel support points 9 play the role of supporting the baffle 7.

[0042] In order to enable the repositioning of the frame 1, please refer to some embodiments. Figures 1 to 4 The bottom of the frame 1 is rotatably connected to four wheels 10, and all the wheels 10 are used to support the movement of the frame 1.

[0043] If it cannot be towed by a tractor to move to another location for cleaning operations, in some embodiments, please refer to [link to relevant documentation]. Figures 1 to 4 The frame 1 has a turntable 11 connected to its bottom end, with two wheels 10 rotatably connected to the bottom end of the turntable 11. The turntable 11 has a circumferential rotational degree of freedom in the horizontal plane. A traction frame 12 is connected to one end of the turntable 11, which is used to connect traction equipment and pull the frame 1 to move. A tractor or similar vehicle can be connected to the traction frame 12 to drag the frame 1, thus enabling screening operations to be performed at any location. The turntable 11 can rotate, and its upper end forms a rotatable connection with the bottom end of the frame 1, such as through a bearing, thereby allowing the frame 1 to be dragged to move. In this invention, the angle between the cleaning roller 2 and the horizontal plane is 10-20°, and in this embodiment, it is 16°. The roller has a diameter of 1.6 meters and a length of 6 meters, and the first conveyor 3 has a length of 5 meters and a width of 60 centimeters.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
