Description

Technical Field

[0001] The utility model relates to the technical field of grain stone removal, in particular to a machine for removing impurities and stones for grain processing. Background Art

[0002] With the change of planting patterns, individual planting has increasingly turned into centralized planting, and the degree of mechanization has become increasingly higher. Many crops are harvested by automated mechanical devices, which reduces labor costs and greatly increases efficiency. However, mechanical automated harvesting will cause the grain to contain pebbles and other debris. In order to make it easier for people to eat, the grain will be de-pebbled before processing.

[0003] Due to the different weights of grain and stones, traditional impurity and stone removal machines use fans to separate the grain and stones. In order not to affect the operation of the fan, a filter is installed at the air outlet to prevent the grain and stones from entering the fan. However, the filter will adhere to too much dust over a long period of use, which greatly reduces the amount of air blown out and makes the stone removal effect worse. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 to 4As shown, the utility model is a machine for removing impurities and stones for grain processing, comprising a box body, a fan 5 and a filter replacement mechanism 7. A feed port is provided on the upper portion of the box body, an air outlet 8 is provided on one side of the box body, and a discharge port is provided on the other side of the box body. The fan 5 is provided at the air outlet 8 and connected to the box body. A gap is provided between the fan 5 and the air outlet 8, and the filter replacement mechanism 7 is provided inside the gap.

[0029] The filter replacement mechanism 7 includes a movable assembly and a plurality of filter assemblies. The movable assembly is connected to the outer surface of the box. The movable assembly is provided with a plurality of filter assemblies. The filter assemblies are movably connected to the air outlet 8.

[0030] The filter assembly includes a slider 707, a frame 705, a filter screen 704, a telescopic tube 709, a first magnetic component 708 and a second magnetic component 710. A slider 707 is provided at both ends of the frame 705. The movable assembly is driven and connected to the slider 707. The filter screen 704 is provided in the middle of the frame 705. The side of the frame 705 close to the fan 5 is connected to the first magnetic component 708 through the telescopic tube 709. The first magnetic component 708 is detachably connected to the fan 5. The side of the frame 705 away from the fan 5 is connected to the second magnetic component 710 through another telescopic tube 709. The second magnetic component 710 is detachably connected to the air outlet 8.

[0031] The working principle of the present invention is as follows: during actual production and use, when it is necessary to remove stones from the grain, the grain can be put into the box from the feed port, and the fan 5 can be operated at the same time, so that the fan 5 will blow the grain that has fallen into the box out of the device through the discharge port, and then the stones will fall into the lower part of the box. When the filter element needs to be cleaned or replaced, the adsorption force of the first magnetic element 708 and the second magnetic element 710 on the fan 5 and the air outlet 8 can be released in advance, and then the moving component can be operated to move the filter 704 that needs to be cleaned to the air outlet 8, and move the new filter 704 to the air outlet 8 to continue working. When the new filter 704 moves to the air outlet 8, the first magnetic element 708 and the second magnetic element 710 can be operated to connect the first magnetic element 708 to the fan 5, and the second magnetic element 710 to the air outlet 8, so that when the fan 5 is running, the wind can be better blown into the inside of the box.

[0032] Furthermore, the moving assembly includes a rotating drive member 701, a transmission belt 706, a lifting rail 703 and a screw 702. The lifting rail 703 is connected to the outer surface of the box body. The sliders 707 at one end of the frame 705 are slidably connected to one lifting rail 703, and the sliders 707 at the other end of the frame 705 are slidably connected to another lifting rail 703. The lifting rails 703 are rotatably connected to one of the screws 702. The screw 702 is inserted into the middle of the slider 707. One screw 702 is connected to the other screw 702 through a transmission belt 706. The rotating drive member 701 is driven and connected to one of the screws 702.

[0033] From the above description, it can be seen that when the filter 704 needs to be replaced, the rotating drive member 701 can be operated to make the rotating drive member 701 drive a screw 702 to rotate, and at the same time, one screw 702 drives another screw 702 to rotate synchronously through the transmission belt 706, and then the screw 702 drives the slider 707 to move, so that the filter 704 that needs to be replaced is moved to the air outlet 8, and the new filter 704 is moved to the air outlet 8 for installation.

[0034] Furthermore, it also includes a fixing base 6, and the fan 5 is detachably connected to the outer surface of the box body through the fixing base 6.

[0035] From the above description, it can be seen that the fan 5 is better connected to the outer surface of the box through the fixing seat 6.

[0036] Furthermore, it also includes a feed hopper 1, and the feed port is fixedly connected to the feed hopper 1.

[0037] From the above description, it can be seen that it is beneficial for the grain to pass through the feed hopper 1 and enter the interior of the box for screening.

[0038] Furthermore, it also includes a residual material removing mechanism. The residual material removing mechanism is arranged inside the box body, and the residual material removing mechanism includes a linear drive member 10, a striking head 11 and an elastic material connecting member 9. The elastic material connecting member 9 is obliquely arranged below the discharge port, and the elastic material connecting member 9 is connected to the inside of the box body. The lower part of the linear drive member 10 is connected to the bottom of the box body, and the upper part of the linear drive member 10 is drive-connected to the striking head 11. The striking head 11 is movably connected to the bottom surface of the elastic material connecting member 9.

[0039] From the above description, it can be seen that after most of the grain is discharged from the outside of the box through the discharge port, the stones and some grain fall onto the elastic material receiving member 9 for collection. Before the stones need to be discharged from the outside of the device, the linear drive member 10 can be operated to drive the striking head 11 to impact the elastic material receiving member 9, so that the grain and stones on the elastic material receiving member 9 bounce up, allowing the remaining grain to be discharged from the discharge port to the outside of the box, and then the stones can be discharged.

[0040] Furthermore, it also includes a discharge hopper 2, and the discharge port is fixedly connected to the discharge hopper 2.

[0041] From the above description, it can be seen that it is beneficial for the grain to be better discharged from the outside of the box through the discharge port for collection.

[0042] Furthermore, it also includes a valve body 13 , and the box body is further provided with a stone discharge port 12 , which is provided above the elastic material receiving member 9 , and the valve body 13 is provided inside the stone discharge port 12 .

[0043] As can be seen from the above description, when it is necessary to discharge the stones on the elastic material connecting member 9, the valve body 13 can be operated to open the stone discharge port 12, so that the stones can be better discharged from the stone discharge port 12 to the outside of the box.

[0044] Furthermore, it also includes supporting legs 43, and a plurality of the supporting legs 43 are fixedly connected to the bottom surface of the box.

[0045] From the above description, it can be seen that this is conducive to more stable operation of the device.

[0046] Furthermore, a PLC controller is included, and the PLC controller is electrically connected to the fan 5 and the filter replacement mechanism 7 respectively.

[0047] From the above description, it can be seen that it is beneficial to adjust the parameters of the impurity removal and stone removal machine for grain processing through the PLC controller, and it is more convenient for operators to operate the impurity removal and stone removal machine for grain processing.
