Due to the accumulation of a large amount of material in the backward direction of the cleaning machine, the equipment cannot quickly retreat, so a conveying screw body needs to be added to the rear of the equipment for cleaning the accumulated material. The addition of a new conveying auger power system not only reduces the silo capacity and unloading efficiency due to the increase in structure volume, but also increases the energy consumption.

[0004] Therefore, we propose a driving system of three spiral cleaning machine to solve the above problems. Through the driving system, one motor reducer power system can control the independent rotation and stop of three spiral bodies. CONTENT OF THE UTILITY MODEL

[0022] Referring to Figs. 1 to 4 The driving system of the three spiral grain cleaning machine shown in the drawing includes fixed frame 7, forward spiral rod 18, broken spiral rod 27, backward spiral rod 35 and rotating driver for driving forward spiral rod 18, broken spiral rod 27 and backward spiral rod 35 to rotate, broken spiral rod 27 is located directly above forward spiral rod 18, backward spiral rod 35 is arranged in the same plane with forward spiral rod 18, and forward spiral rod 18, broken spiral rod 27 and backward spiral rod 35 are rotatably installed on fixed frame 7.

[0023] When it is needed to scatter the hardened material, the rotating driver drives forward spiral rod 18 and broken spiral rod 27 to rotate simultaneously, and backward spiral rod 35 stops rotating.

[0024] When the material needs to be discharged, the rotary driver drives the forward screw 18 to rotate, and the broken screw 27 and the backward screw 35 stop rotating;

[0025] When the clearing machine is buried, the rotary driver drives the backward screw 35 to rotate, and the forward screw 18 and the broken screw 27 stop rotating.

[0026] The working mode of the triple-screw clearing machine: the clearing machine advances, the forward screw 18 rotates, and the material in front of the clearing machine is conveyed to the center material port, at this time the backward screw 35 does not rotate. When encountering hardened material, the forward screw 18 and the broken screw 27 rotate at the same time, and the hardened material in front of the clearing machine is broken and conveyed to the center material port through the action of clamping and extrusion. A large amount of material in front of the clearing machine collapses, the clearing machine is buried, the backward screw 35 rotates, and the collapsed material behind the clearing machine is conveyed to the center material port. After the collapsed material behind the clearing machine is conveyed away, the backward resistance decreases, and the clearing machine can retreat quickly. When the forward resistance of the forward screw 18 in front is reduced, the clockwise rotation is switched again, and the positive discharge is restarted.

[0027] The rotary driver includes a speed reducer 16 and a one-way clutch 17, the input end of the speed reducer 16 is connected with the motor, the speed reducer 16 has two output ends, one of the output ends of the speed reducer 16 is connected with the forward screw 18 through the one-way clutch 17, the other output end of the speed reducer 16 is fixedly provided with a rotary shaft 13, the rotary shaft 13 is connected with the broken screw 27 through a gear set, and the rotary shaft 13 is connected with the backward screw 35 through a chain wheel set, a separation mechanism is arranged between the gear set and the broken screw 27, a one-way clutch 34 is arranged between the chain wheel set and the backward screw 35, and the one-way clutch 17 and the one-way clutch 34 are reversely arranged. When the one-way clutch 34 is driven to work, the one-way clutch 17 is in a disconnected state, that is, the separate work between the backward screw 35 and the forward screw 18 can be realized. Through the work of the separation mechanism, the power of the gear set cannot be transmitted to the broken screw 27, so that the broken screw 27 stops moving. The control requirements of the above three situations can be met.

[0028] The sprocket set comprises a bearing seat assembly 31, a rotating shaft 32, a driven sprocket 33 and a driving sprocket 12, the driving sprocket 12 is fixedly installed on the rotating shaft 13, the driving sprocket 12 is connected with the driven sprocket 33 through a chain, the driven sprocket 33 is fixedly installed on the rotating shaft 32, the rotating shaft 32 is rotatably installed on the fixed frame 7 through the bearing seat assembly 31, the end of the rotating shaft 32 is fixedly connected with the input end of the one-way clutch 34, and the end of the backward spiral rod 35 is fixedly connected with the output end of the one-way clutch 34. When the driving sprocket 12 is driven to rotate, the driving sprocket 12 drives the driven sprocket 33 to rotate through the chain, so that the backward spiral rod 35 is driven to rotate through the one-way clutch 34, and when the driving sprocket 12 reversely rotates, the backward spiral rod 35 cannot be driven to rotate.

[0029] The gear set comprises a bearing seat assembly 22, a driven gear 23, a rotating shaft 26 and a driving gear 14, the driving gear 14 is fixedly installed on the rotating shaft 13, the driving gear 14 is connected with the driven gear 23, the driven gear 23 is rotatably installed on the bearing seat assembly 22 through a support shaft, the rotating shaft 26 is rotatably installed on the fixed frame 7, one end of the rotating shaft 26 is fixedly connected with the crushing spiral rod 27, and the other end of the rotating shaft 26 is drivingly connected with the support shaft through a separation mechanism. The driving gear 14 is rotated, so that the driven gear 23 drives the support shaft to rotate, if the separation mechanism is not separated, the separation mechanism is driven to rotate, so that the rotating shaft 26 is driven to rotate, and finally the crushing spiral rod 27 is driven to rotate.

[0030] The separation mechanism comprises a clutch lever assembly 6, a clutch claw 24 and a clutch claw 25, the clutch claw 24 is fixedly connected with the support shaft, the clutch claw 25 is slidingly connected with the rotating shaft 26, the clutch lever assembly 6 is fixedly installed on the fixed frame 7, and the clutch lever assembly 6 is used for separating the clutch claw 25 from the clutch claw 24. When it is needed to separate the clutch claw 24 from the clutch claw 25, the clutch claw 25 is pushed away from the clutch claw 24 through the clutch lever assembly 6, so that the two are separated, the power of the support shaft cannot be transmitted to the rotating shaft 26, and the crushing spiral rod 27 cannot rotate, and vice versa. The clutch claw 24 and the clutch claw 25 are clamped, so that the crushing spiral rod 27 is driven to rotate by the support shaft.

[0031] The clutching lever assembly 6 comprises a cylinder 61, a lever 62 and a hinged slider 63, one end of the hinged slider 63 being hinged to the top of the clutching tiger tooth two 25, the other end of the hinged slider 63 being slidingly connected to one end of the lever 62, the middle part of the lever 62 being rotatably connected to the fixed frame 7, the tail of the cylinder 61 being hinged to the fixed frame 7, and the end of the cylinder 61 being hinged to the other end of the lever 62. By controlling the cylinder 61 to work, the cylinder 61 pushes the lever 62 to rotate along the hinge, the lever 62 pushes the hinged slider 63 to slide, and the hinged slider 63 pushes the clutching tiger tooth two 25 to slide horizontally, so that the clutching tiger tooth two 25 moves away from or approaches the clutching tiger tooth one 24.
