[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The embodiment of the utility model provides a separation mechanism for a Rehmannia glutinosa excavation device, such as Figures 1-6 As shown, a separation mechanism for a Rehmannia glutinosa excavation device includes a base 1 and a separation mechanism 2; a support assembly 3 is provided at the top of the base 1, a spring 4 is provided at the top of the support assembly 3, a separation screen 5 is installed at the top of the spring 4, and baffles 6 are provided on both sides of the top of the separation screen 5;

[0031] A fixing seat 9 is provided on one side of the top of the base 1, a separation mechanism 2 is provided on one side of the fixing seat 9, and a filter port 7 is provided inside the base 1;

[0032] A mounting groove 10 is provided inside the base 1 on one side of the filter port 7 , and an auxiliary structure 8 is provided inside the mounting groove 10 .

[0033] In a further preferred embodiment of the present invention, Figures 1-6 As shown: the separation mechanism 2 includes a motor 201, a disc 202, a fixing column 203, a connecting frame 204, a connecting column 205 and a connecting rod 206, and the motor 201 is arranged on one side of the fixing base 9;

[0034] A connecting rod 206 is provided at one end of the motor 201, and a disc 202 is provided at one end of the connecting rod 206;

[0035] A fixing post 203 is provided at one end of the disc 202, a connecting frame 204 is provided on the outside of the fixing post 203, and a connecting post 205 is provided on one side of the separation screen 5;

[0036] One end of the connecting frame 204 is sleeved on the outside of the fixed column 203, and the other end of the connecting frame 204 is sleeved on the outside of the connecting column 205. A movable connection is formed between the fixed column 203 and the connecting frame 204. The two ends of the connecting frame 204 are movably connected to the fixed column 203 and the connecting column 205 respectively, so that the disc 202 can drive the separation screen 5 on one side of the connecting column 205 to reciprocate through the connecting frame 204 without getting stuck. In addition, this left and right reciprocating separation can make the Rehmannia glutinosa better in separating from the soil.

[0037] Specifically, in this embodiment: when separating the Rehmannia root, the base 1 is installed at the rear end of the Rehmannia root excavation device, and when the excavated Rehmannia root is transported to the top of the separation screen 5 through the conveyor belt, the external power supply starts the motor 201, and the motor 201 will drive the disc 202 to rotate through the connecting rod 206 after starting. The rotating disc 202 will drive the connecting column 205 on one side of the separation screen 5 to move through the cooperation of the fixed column 203 and the connecting frame 204, thereby indirectly driving the separation screen 5 to perform a reciprocating movement. When the separation screen 5 reciprocates, it will drive the Rehmannia root and the soil to have a slight collision on the top of the separation screen 5, knocking down the soil on the surface of the Rehmannia root, so that the effect of separating the Rehmannia root and the soil is better, and the separated Rehmannia root will be discharged along one side of the separation screen 5, and the separated soil will fall into the inside of the filter port 7 for re-separation.

[0038] In a further preferred embodiment of the present invention, Figures 1-6As shown: the auxiliary structure 8 includes a screw 801, a wire sleeve 802, a cleaning brush holder 803, a pulley 804, a rotating wheel 805 and a bevel gear set 806. The screw 801 is arranged inside the mounting groove 10, and the wire sleeve 802 is arranged on the outside of the screw 801. The top of the wire sleeve 802 is provided with a cleaning brush holder 803;

[0039] A bevel gear set 806 is provided at one end of the screw rod 801, and a rotating wheel 805 is provided on one side of the bevel gear set 806;

[0040] The pulley 804 is arranged on the outer side of one end of the connecting rod 206, and the pulley 804 is connected to the rotating wheel 805 through a belt.

[0041] The outer side of the screw rod 801 is provided with an external thread, and the inner side of the wire sleeve 802 is provided with an internal thread. The screw rod 801 and the wire sleeve 802 form a threaded connection. The threaded connection makes it more convenient to move the cleaning brush holder 803 back and forth, saving more time during cleaning.

[0042] The bottom end of the cleaning brush holder 803 is provided with a plurality of bristles, and the bristles are arranged at equal intervals at the bottom end of the cleaning brush holder 803. The use of a plurality of bristles can make the cleaning brush holder 803 more comprehensive when brushing the filter screen inside the filter port 7, and the brushing effect is better, thereby improving the separation effect.

[0043] Specifically, in this embodiment, when the separated soil falls into the inside of the filter port 7, the filter screen inside it will separate the soil again, separating the smaller Rehmannia root in the soil. During separation, the motor 201 will drive the rotating wheel 805 to rotate through the pulley 804. When the rotating wheel 805 rotates, it will drive the screw rod 801 to rotate through the bevel gear set 806. The rotating screw rod 801 will drive the cleaning brush holder 803 to move back and forth inside the filter port 7 through the wire sleeve 802, brushing the soil inside the filter port 7 to prevent the soil from clogging the filter screen and affecting the separation effect, and finally completing the separation of the Rehmannia root.
