[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments of the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description clearly, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0039] like Figure 1-4 As shown, the multifunctional rice drum primary cleaning screen comprises: a frame upper cover 1, a front drum screen 2, a rear drum screen 3, a frame lower cover 4, a discharge port 5, a suction trough 6, a feeding crawler 7, a feed hopper 8, a driving motor 9, a driving shaft 10, a driving middle shaft rod 11, a debris removal auger 12, a frame support frame 13, a vertical air duct 14, a dust removal fan 15, a small material discharge port 16, a crawler support frame 17, and a driving crawler motor 18. The frame upper cover 1 has an accommodating space inside; the front drum screen 2 is tiltedly placed in the accommodating space of the frame upper cover 1; the rear drum screen 3, one end of the rear drum screen 3 is fixedly connected to the front drum screen 2, and the other end of the rear drum screen 3 is drivingly connected to the inner wall of the frame;

[0040] In this embodiment, the frame lower cover 4 is located below the frame upper cover 1 and is locked with the frame upper cover 1; it is installed on the frame lower cover 4, located below the rear cylindrical screen 3, and is connected to the rear cylindrical screen 3; the suction trough 6 is located below the frame lower cover 5 and is fixedly connected to the frame lower cover 5; the feeding crawler 7 is located directly below the discharge port 4; the feed hopper 8 is fixedly set on the frame upper cover 1 and is connected to the front cylindrical screen 2; the drive motor 9 is fixedly set on one side of the frame upper cover 1. In order to improve the processing efficiency, the front cylindrical screen 2 and the rear cylindrical screen 3 adopt a segmented design, and then the segmented cylinder is lengthened to increase the cylinder capacity, and a debris removal auger is set on the driving middle shaft 11, so that some large straw materials can be freely screened. Use to change the material from linear to planar, better remove bran, more uniform air intake and more thorough impurity removal, the impurity removal rate of the equipment reaches 92%. The equipment is equipped with a frequency converter to change the speed according to the impurity content of the material to meet the cleaning requirements. The higher the impurity content, the faster the speed and the higher the work efficiency.

[0041] The distinction between the upper cover and the lower cover of the frame is to facilitate the installation of the internal structure. The setting of the frame support frame ensures stability during use. This multifunctional rice cylinder primary cleaning screen is connected to the dust removal fan and the brake dragon through the suction trough to form a self-dust removal system, which greatly reduces the impurity content of the material after cleaning.

[0042] In this embodiment, the driving shaft 10 is installed on the outside of the frame cover 1, and is connected to the driving motor 9 through a rotating belt transmission; one end of the driving middle shaft 11 is connected to the driving shaft 10, and the rod body of the driving middle shaft 11 is provided with a plurality of metal connecting rods, and the driving middle shaft 11 is fixedly connected to the inner wall of the front cylindrical screen 2 through a plurality of metal connecting rods. The debris removal auger 12 is placed on the driving middle shaft 11, and the debris removal auger 12 is inside the rear cylindrical screen 3; in fact, the driving shaft 10 is connected to the front cylindrical screen 2 and the rear cylindrical screen 3 through the driving middle shaft 11, so that the kinetic energy generated by the motor drives the front cylindrical screen 2 and the rear cylindrical screen 3 to rotate, so that the debris can be normally screened.

[0043] In this embodiment, the frame support frame 13 is placed on the outside of the frame lower cover 5 and fixedly connected to the frame lower cover 5; one end of the vertical air duct 14 is connected to the suction trough 6, and a brake dragon is installed outside the frame upper cover 1, and the other end of the vertical air duct 14 is fixedly connected to the exhaust port of the brake dragon; the dust removal fan 15 is located above the brake dragon; the small material discharge port 16 is installed at the bottom of the brake dragon. The crawler support frame 17 is placed on both sides of the feeding crawler 7, and the crawler support frame 17 is rotatably connected to the feeding crawler 7 through a rotating shaft; the driving crawler motor 18 is placed on the crawler support frame 17, and the driving crawler motor 18 is rotatably connected to the crawler support frame 17. The frame support frame 13 ensures that the overall cylinder primary screening machine will not shake during operation, affecting the screening efficiency.

[0044] During specific operation, the material is poured from the feed hopper, and the drive motor 9 is started. The electric energy drives the motor to rotate, and the motor rotation drives the rubber rotating belt to rotate, and the rubber rotating belt rotation drives the drive shaft 10. After the drive shaft 10 obtains kinetic energy, it drives the driving center shaft 11. Because the driving center shaft 11 is connected to the front cylindrical screen 2 through several metal support rods, the driving center shaft 11 drives the front cylindrical screen 2 to rotate. The front cylindrical screen 2 is fixedly connected to the rear cylindrical screen 3 to drive the rear cylindrical screen 3 to rotate. The material first passes through the sieve holes of the front cylindrical screen to screen out small impurities, and the large materials continue to move forward. The small impurities pass through the vertical air duct 14 through the suction trough 6, and are introduced into the brake dragon 16 by the vertical air duct 14. The dust removal fan 15 transports the grain impurities upward, and the small materials after the impurities are screened out are poured out at the small material discharge port 17. The large materials enter the rear cylindrical screen, are cut into small pieces by the impurity removal auger, and are screened out from the large-hole filter screen, and then fall directly onto the crawler from the discharge port 4. The crawler conveyor pours out the sieved large materials in a waterfall shape.

[0045] In this embodiment, small holes can be provided on the blades of the debris removal auger, so that the straw can be cut into finer pieces.

[0046] It is worth noting that the entire device can control the motor through the main control button. Since the device matched with the control button is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
