[0002] Cyperus oleiferus is an annual plant of the Cyperaceae family. It is a high-quality, high-yield, and economic crop that integrates grain, oil, livestock, and feed and has broad prospects for comprehensive utilization. Cyperus oleiferus grows grass on the ground and bears fruit underground, so it needs to be cleaned. After cleaning, the remaining soil, leaves, and fruits need to be separated. There are many existing separation equipment, but the separation effect is poor, which seriously increases the labor intensity and processing procedures. Summary of the invention

[0018] One end of the threshing bin 3 of the utility model is the bean leaf outlet 9 after separation, and the other end is the bean leaf inlet without separation; the bean leaf outlet 9 after separation is the outlet after the soil, leaves and cyperus rotundus have been separated, and the vibrating screen is connected behind it to screen out the cyperus rotundus. The unseparated bean leaf inlet is the crop with leaves and beans together and with some soil, which is sent to the threshing bin 3 from this port. After some mixed crops have been initially removed by transportation and other procedures, that is, most of the soil, broken leaves, etc. have been screened out, this part is seen Figure 1 and Figure 4 .

[0019] See Figure 1 and Figure 2, a threshing separation main shaft 6 is installed through bearings in the middle of the two side walls of the threshing bin 3, and multiple screen drum shafts 7 are installed through bearings at the bottom of the two side walls of the threshing bin 3, and the multiple screen drum shafts 7 are arranged in an arc shape. A main shaft gear 5 and a screen drum shaft gear 8 are installed on the threshing separation main shaft 6 and the screen drum shaft 7 respectively, and the main shaft gear 5 and the screen drum shaft gear 8 are connected through a linkage chain 2; a threshing mechanism 1 is installed on the threshing separation main shaft 6 inside the threshing bin 3, and a screen drum 4 is installed on the screen drum shaft 7 inside the threshing bin 3. The threshing separation main shaft 6 and the screen drum shaft 7 are both shaft rods that penetrate the two side walls of the threshing bin 3, so both ends are connected to the two side walls of the threshing bin 3 through bearings to ensure that the threshing separation main shaft 6 and the screen drum shaft 7 can both rotate. The screen drum shaft 7 adopts multiple (five in the figure of the utility model), and the arrangement method adopts an arc shape with a concave middle. The threshing separation main shaft 6 and the screen drum shaft 7 are respectively fixedly mounted with the main shaft gear 5 and the screen drum shaft gear 8 on one end of the threshing separation main shaft 6 and the screen drum shaft 7 extending out of the side wall of the threshing bin 3. Figure 2 , these gears are connected by a chain (linkage chain 2), so that these gears will rotate synchronously. The threshing separation main shaft 6 is connected to a power input mechanism (such as a rotating motor, a power source of other mechanisms, etc., as long as it can be connected to the threshing separation main shaft 6 and can drive the mechanism to rotate, it can be determined according to the actual situation). Therefore, when the power mechanism drives the threshing separation main shaft 6 and the main shaft gear 5 to rotate, it also drives the screen drum shaft 7 and the screen drum shaft gear 8 to rotate synchronously.

[0020] Threshing mechanism 1: A fixed connection disk 11 is installed on the threshing separation main shaft 6, and a plurality of shaft tube fixing plates 15 are installed on the fixed connection disk 11. The shaft tube 13 is installed on the fixed connection disk 11 through the shaft tube fixing plates 15, and the shaft tube 13 is installed with bow teeth 12 and spike teeth 14 at intervals; see Figure 4 and Figure 7 The threshing mechanism 1 is a device for separating fruits, leaves and soil. It takes the threshing separation main shaft 6 as the axis, that is, it is installed on the threshing separation main shaft 6. When the threshing separation main shaft 6 rotates, the threshing mechanism 1 will also rotate. The fixed connecting plate 11 is a connecting component fixed to the threshing separation main shaft 6. A circle of shaft tubes 13 are installed on it through the shaft tube fixing plate 15. Bow teeth 12 or spike teeth 14 are installed on these shaft tubes at intervals. That is, if one shaft tube is installed with bow teeth 12, the two adjacent shaft tubes are installed with spike teeth 14. The shape of the bow teeth 12 can be seen in FIG. Figure 7 , is a bent shape, and is installed at an angle relative to the threshing separation main shaft 6, so that when the threshing mechanism 1 rotates, the bow teeth 12 can beat the material (separate the soil, leaves and fruits by beating), and can also pull the separated fruits and leaves into the separated bean leaf outlet 9 like a palm, and finally send them out. Figure 7 , which is a columnar, tooth-like structure that increases the ability to tear and separate soil, leaves and fruit.

[0021] Screen drum 4: single structure see Figure 5 and Figure 6 , a connecting plate 41 is installed on the screen drum shaft 7, and a steel pipe 42 is installed on the connecting plate 41 through which the steel pipe 42 is inserted; the screen drum shaft 7 of the utility model has five, each of which is installed with a steel pipe 42, see Figure 4 The sieve drum 4 formed by five steel pipes 42 is concave, and the gap between each sieve drum 4 is smaller than the particle size of the cyperus oleifera, and the gap between each steel pipe 42 is also smaller than the particle size of the cyperus oleifera. In this way, the soil, leaves and fruits separated by the threshing mechanism 1 will fall into the concave formed by the sieve drum 4. The soil is basically at the bottom, and because its particle size is large, when the sieve drum 4 rolls, it leaks downward from the gaps between the sieve drums 4 or the gaps between the steel pipes 42. Even if there are large particles of soil, they are hit and broken by the sieve drum 4 and then leak downward, while the fruit particles will not be broken, so they are always kept in the concave formed by the sieve drum 4. When the leaves and fruits accumulate to a certain height, they will be pulled by the threshing mechanism 1 to the bean leaf outlet 9 after separation, and finally sent to the selection screening machine for leaf and fruit separation.

[0022] Arc protection plates 10 are installed on both sides of the lower end of the threshing bin 3. The arc protection plates 10 are installed on the threshing bin 3, and the bottom ends are located on the screen drums 4 at both ends to prevent the separated soil, leaves and fruits from leaking out directly, ensuring that the cyperus rotundus will not leak out from below, and at the same time ensuring that the soil can only leak out through the screen drum 4.

[0023] The arc-shaped protection plate 10 of the utility model is provided with an escape hole 16. Sometimes, when the threshing mechanism 1 pulls the fruit leaves in the concave shape formed by the screen cylinder 4 into the bean leaf outlet 9 after separation, some soil will be brought up and will leak out through the escape hole 16, and the escape hole 16 must be smaller than the diameter of the cyperus oleifera grains.
