The outer walls of the four fixed seats 11 are slidably connected with pull rods 9. Two second limiting block grooves 17 are opened inside the grooves opened in the outer wall fixing blocks of the two feed pipes 12. The inner parts of the two second limiting block grooves 17 are The two parts are slidably connected to the limit block 18, and the ends of the two pull rods 9 close to the limit block 18 are slidably extended to the inside of the second limit block groove 17 and are respectively fixedly connected to the outer wall of one end of the corresponding limit block 18. The outer walls of the lower ends of the two raw material bins 10 are provided with two first limit block grooves 14, and the ends of the two limit blocks 18 close to the first limit block groove 14 are respectively in contact with the inner walls of the corresponding first limit block groove 14. The outer walls of the two pull rods 9 are sleeved with return springs 16, and the two ends of the two return springs 16 are respectively fixedly connected to the outer walls of the corresponding pull rods 9 and the inner walls of the second limit block groove 17, and the outer walls of the two fixed blocks 6 are respectively slidably connected to the inside of the grooves opened on the outer walls of the corresponding support plates 5.

[0048] Among them, one end of the two feeding pipes 12 close to the support plate 5 is fixedly extended to the outside of the support plate 5, a mixing tank 2 is arranged on the support seat 1, and the mixing tank 2 is rotatably connected with the stirring shaft 7 inside. The outer wall of the end of the two feeding pipes 12 away from the support plate 5 is slidably connected with a push rod 13, and two fixed blocks on the outer wall of the mixing tank 2 are installed with a one-way valve 8. Pistons 15 are installed inside the two feeding pipes 12, and the ends of the two push rods 13 close to the feeding pipes 12 are slidably extended to the inside of the feeding pipes 12 and are respectively fixedly connected to the outer wall of one end of the corresponding piston 15. The upper surface of the mixing tank 2 is fixedly connected with a motor 4, and the output end of the motor 4 rotates and extends to the inside of the mixing tank 2 and is fixedly connected to one end of the stirring shaft 7.

[0049] Furthermore, when using the device, it is started by connecting an external power supply. First, the material to be mixed is placed into the raw material bin 10, and then the raw material inside the raw material bin 10 enters the feed pipe 12. Then, the push rod 13 is pushed to move in the opposite direction to drive the piston 15 to move in the opposite direction, and at the same time, the material inside the feed pipe 12 enters the mixing tank 2 through the one-way valve 8. Then, the motor 4 is started, and the stirring shaft 7 is driven to rotate by the output end of the motor 4 to mix the materials. Then, the discharge pipe 3 is connected to the external equipment, and then the mixed material can be transported to the inside of the external equipment through the discharge pipe 3.

[0050] Furthermore, when the raw material bin 10 needs to be cleaned, the pull rod 9 is pulled in the opposite direction to drive the return spring 16 to contract and drive the limit block 18 to move in the opposite direction. Then, the limit block 18 moves in the opposite direction to break contact with the inside of the first limit block groove 14. Then, the raw material bin 10 can be directly removed from the delivery pipe 12 after its limit block 18 limits it.

[0051] By pulling the pull rod 9 in the limit device to move in the opposite direction, the return spring 16 is contracted and the limit block 18 is moved in the opposite direction. Then, the limit block 18 is moved in the opposite direction to make it out of contact with the inside of the first limit block groove 14. Then, the raw material bin 10 can be directly removed from the feed pipe 12 after its limit block 18 limits it. This facilitates the disassembly of the raw material bin 10 and avoids the need for staff to use tools to disassemble it, effectively improving the practicality and effectiveness of the equipment. By pushing the push rod 13 to move in the opposite direction, the piston 15 is moved in the opposite direction, and the material inside the feed pipe 12 enters the interior of the mixing tank 2 through the one-way valve 8. Then the output end of the motor 4 rotates to drive the stirring shaft 7 to rotate to mix the materials. This accelerates the mixing of materials, effectively improves the mixing efficiency of the equipment, and at the same time improves the work efficiency of the staff.

[0052] Working principle: first, place the material to be mixed into the raw material bin 10, then the raw materials in the raw material bin 10 will enter the feed pipe 12, and then push the push rod 13 to move in the opposite direction to drive the piston 15 to move in the opposite direction, while bringing the material in the feed pipe 12 into the mixing tank 2 through the one-way valve 8, and then start the motor 4, and rotate the stirring shaft 7 through the output end of the motor 4 to mix the materials, and then connect the discharge pipe 3 to the external equipment, and then the mixed material can be transported to the inside of the external equipment through the discharge pipe 3, and then when the raw material bin 10 needs to be cleaned, pull the pull rod 9 to move in the opposite direction to drive the return spring 16 to contract and drive the limit block 18 to move in the opposite direction, and then the limit block 18 moves in the opposite direction to make it out of contact with the inside of the first limit block groove 14, and then the raw material bin 10 can be directly removed from the feed pipe 12 after its limit block 18 limits it.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
