Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, and in particular relates to a biomass fuel sorting device. Background Art

[0002] Biomass fuel refers to fuel made from agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.) or other organic matter (such as animal feces, organic garbage, etc.) through a specific process. It is different from traditional fossil fuels (such as coal, oil, natural gas, etc.) and has the advantages of being renewable, low-pollution, and sustainable.

[0003] In current agricultural production, with the continuous improvement of agricultural mechanization level, the operation efficiency of crop harvest season has been significantly improved. However, while mechanized operation brings high efficiency, it also brings a problem: the harvested straw often carries a part of grain and impurities, which not only causes food waste, but also affects the quality of straw as fuel, and further affects the operation efficiency of straw power plant. Based on this, a biomass fuel sorting device is proposed to sort out the residual grain and straw in the straw, which can improve the quality of straw as fuel and improve the operation level of straw power plant.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1—5 shows: a biomass fuel sorting device, comprising a leg 1, a spring 2 is arranged at the top of the leg 1, a frame 3 is installed on the spring 2, a main support frame 14 is arranged on the frame 3, a screen 4 is laid on the main support frame 14, a collecting trough 5 is formed at the bottom end of the frame 3, a feed port 6 is arranged at the bottom end of the collecting trough 5, a vibration motor 7 and a controller 13 are installed on the frame 3, exhaust ports 8 and fans 9 are arranged on both sides of the frame 3, a plurality of beaters 10 are rotatably installed above the screen 4, the beaters 10 are connected to the main motor 12 through a chain transmission mechanism 11, and the main The motor 12 is mounted on the frame 3. During the process of the straw vibrating and screening on the screen 4, the beater 10 repeatedly beats the straw to separate the residual grain from the shell, thereby realizing efficient sorting of the straw. At the same time, when the fan 9 is working, the straw with a small volume that passes through the sieve holes of the screen 4 can be effectively separated by air selection. The number of the fans 9 is multiple, and they are equidistantly arranged along the extension direction of the frame 3. The multiple fans 9 work at the same time, and the straw and grain falling from any area of ​​the screen 4 are efficiently separated by air selection. The beater 10 includes a main shaft 101 and a hammer 102. The main shaft 101 is rotatably mounted on the frame 3. The sprocket in the chain transmission mechanism 11 is installed at one end of the main shaft 101. The use of the chain transmission mechanism 11 enables the main motor 12 to effectively drive multiple beaters 10 to rotate stably at the same time, thereby efficiently beating the material conveyed on the screen 4, and realizing efficient shelling and screening. The number of the percussion hammers 102 is multiple, and they are equidistantly arranged along the axis direction of the main shaft 101. One end of the percussion hammer 102 is connected to the main shaft 101 and the other end is a spherical structure. The percussion hammer 102 is quickly swung under the drive of the main shaft 101, and the spherical structure formed at the head end is used to beat the straw, thereby realizing effective shelling of the remaining food in the straw. The main support frame 14 is a square frame structure, the screen 4 is laid flat on the main support frame 14, the main support frame 14 can provide stable support for the screen 4, ensure the stability of the use of the screen 4, the frame 3 is a U-shaped groove structure, and the frame 3 is a structure with one end high and the other end low in the opening direction between the two flanges. During the vibration of the frame 3, the straw moves from the higher side of the screen 4 to the lower side, realizing automatic transportation and unloading. The controller 13 includes a control switch and a relay. The controller 13 is electrically connected to the vibration motor 7, the fan 9 and the main motor 12. The operator can conveniently control the operation of the device through the controller 13.

[0035] The working principle of the present technical solution is as follows: the vibration motor 7, the fan 9 and the main motor 12 are started. When the vibration motor 7 is working, the frame 3 is driven to vibrate at a high speed as a whole under the buffer support of the spring 2. Since one end of the frame 3 is lower, the straw fallen on the screen 4 will move to the lower end of the frame 3 and be discharged; in the process of the straw moving, the main motor 12 drives the multiple beaters 10 to rotate through the chain transmission mechanism 11, and the hammer 102 rotates and beats the straw on the screen 4 driven by the main shaft 101, so that part of the unhulled wheat is separated from the straw. After being beaten or vibrated, the wheat falls into the collecting trough 5 through the sieve holes of the screen 4 and is discharged through the discharge port 6; after some straw debris whose volume is smaller than the sieve holes of the screen 4 falls into the collecting trough 5, the flowing air transported by the fan 9 blows the light-weight and low-density straw out to one side of the device through the exhaust port 8, thereby realizing efficient separation.
