In the embodiment of the present application, as shown in fig. 3, the triggering structure 33 of the blanking mechanism 3 includes a transmission component 331 and a triggering rod 332, and the transmission component 331 is located at one side of the blanking door 32 and is in transmission connection with the blanking door 32. The trigger rod 332 is located at the top end of the transmission component 331 and is fixedly connected with the transmission component 331. The trigger lever 332 extends at least partially relative to the first end of the lower cartridge 31.

Taking the preset position as the top of the storage bin 2 as an example, when the discharging barrel 31 rises relative to the storage bin 2, the trigger lever 332 gradually approaches the top of the storage bin 2, the trigger lever 332 is in contact with the top of the storage bin 2, and along with the continuous rising of the discharging barrel 31, the trigger lever 332 is pressed by the top of the storage bin 2, so that the discharging door 32 is driven to be opened, and discharging is completed.

In the embodiment of the present application, as shown in fig. 3, the discharging door 32 is pivotally connected to the discharging barrel 31, and the discharging door 32 can rotate around a pivotal axis m. As shown in fig. 4, the feeding gate 32 may include a gate plate 321 and a gate shaft 322, the gate plate 321 is sleeved outside the gate shaft 322 and connected to the gate shaft 322, the gate shaft 322 is rotatably connected to the feeding barrel 31, and the rotation of the gate shaft 322 drives the gate plate 321 to rotate around the axis of the gate shaft 322. In the embodiment of the present application, the door shaft 322 is detachably connected to the door panel 321, and in other examples, the door shaft 322 may be fixedly connected to the door panel 321.

As shown in fig. 3, the transmission component 331 of the triggering structure 33 includes a gear 3311 and a rack 3312, and the gear 3311 is coaxially disposed with the pivot axis m of the discharging door 32 and connected to the discharging door 32. The rack 3312 is positioned at one side of the gear 3311 and engaged with the gear 3311, and one end of the rack 3312 is connected to the trigger lever 332. When the trigger lever 332 is pressed, the trigger lever 332 drives the rack 3312 to move, the rack 3312 drives the gear 3311 to rotate, and the gear 3311 drives the discharge door 32 to rotate.

When the trigger rod 332 is pressed down relative to the charging barrel 31, the rack 3312 may descend relative to the charging barrel 31 along with the trigger rod 332, and the rack 3312 moves downward, so as to drive the gear 3311 to rotate around the pivot axis m of the charging door 32, so that the charging door 32 is switched from the closed state to the open state. Similarly, when the triggering rod 332 ascends relative to the lower charging barrel 31, the rack 3312 also ascends, and the rack 3312 can drive the gear 3311 to rotate around the pivot axis m of the discharging door 32, so that the discharging door 32 is switched from the open state to the closed state.

Fig. 5 is a schematic structural diagram of a trigger structure 33 according to an embodiment of the present application. As shown in fig. 5, in the triggering mechanism 33, the rack 3312 of the driving member 331 includes an engaging portion 3312a and a guide portion 3312 b. The engagement portion 3312a of the rack 3312 is engaged with the gear 3311, and the trigger lever 332 is fixedly connected to one end of the engagement portion 3312 a. The guide portion 3312b of the rack 3312 is located on a side of the engagement portion 3312a away from the gear 3311 (i.e., on a side opposite to the teeth on the rack 3312), and is connected to the engagement portion 3312 a. Fig. 6 is a top view of a blanking mechanism provided in an embodiment of the present application. As shown in fig. 6, the lower cylinder 31 has a guide groove 3123, and the guide groove 3123 extends in a longitudinal direction of the lower cylinder 31. The guide portion 3312b is located at least partially in the guide groove 3123.

When the rack 3312 is lifted up and down relative to the lower barrel 31, the guide portion 3312b can ensure that the movement of the rack 3312 is more stable, thereby ensuring the stability of the driving member 331 in operation.

Alternatively, the guide portion 3312b has a guide hole 3312c, and the axial direction of the guide hole 3312c is the same as the longitudinal direction of the feed cylinder 31. Fig. 7 is a sectional view taken along the direction a-a of fig. 6, and as shown in fig. 7, the lower cylinder 31 may have guide posts 3124 at positions corresponding to the guide holes 3312c of the guide portion 3312 b. The guide portion 3312b is fitted over the guide post 3124 of the lower feed cylinder 31 through the guide hole 3312c, and the guide post 3124 is fitted into the guide hole 3312c with a clearance. The guide holes 3312c of the guide portions 3312b are fitted with the guide posts 3124 of the feed cylinder 31, so that the process of the lifting movement of the rack 3312 is more stable, thereby ensuring the stability of the transmission assembly 331 during operation.

As shown in fig. 7, the triggering structure 33 further includes an elastic restoring member 333, the elastic restoring member 333 is located at an end of the rack 3312 opposite to the triggering rod 332, one end of the elastic restoring member 333 is connected to the guide portion 3312b of the rack 3312, the other end of the elastic restoring member 333 is connected to the lower cylinder 31, and an elastic direction of the elastic restoring member 333 is parallel to an ascending and descending direction of the lower cylinder 31 relative to the storage bin 2.

When the trigger lever 332 is pressed to lower the rack 3312 relative to the lower barrel 31, the elastic restoring member 333 is compressed. When the trigger lever 332 is gradually far away from the top of the storage bin 2, the elastic reset piece 333 gradually produces to apply an elastic force to the rack 3312, so as to push the rack 3312 to ascend relative to the charging barrel 31, and drive the gear 3311 to rotate, so that the charging door 32 is switched from an open state to a closed state, and the reset of the charging door 32 and the transmission component 331 is realized.

The elastic restoring member 333 may be a spring, one end of which may be connected to the guide portion 3312b of the rack 3312, and the other end of the elastic restoring member 333 may be connected to the lower feed cylinder 31, and the spring may be fitted over the guide post of the lower feed cylinder 31. Thus, the deformation of the spring in the direction perpendicular to the axis of the guide post can be reduced, thereby ensuring the stability of the driving member 331 during operation. The elastic restoring member 333 may also be a metal plate having elasticity, a piston mechanism having a restoring function, etc., and will not be described herein.

In other examples, the elastic restoring member 333 may be disposed at an end of the engaging portion 3312a away from the trigger rod 332, and also serve to restore the feeding door 32 and the driving member 331.

The elevating mechanism 34 includes a lead screw 341, an elevating member 342, and a driving member 343. The screw 341 is located on the side of the lower barrel 31. The threaded spindle 341 is parallel to the axis of the feed cylinder 31 and is rotatably connected to the support 1. The lifting member 342 has a threaded hole, the lifting member 342 is sleeved outside the screw 341 through the threaded hole and is in threaded engagement with the screw 341, and the lifting member 342 is connected to the feed cylinder 31.

The controller can be fixed on the motor, also can be fixed on support 1, and electric connection between controller and the motor is used for the operating condition of control motor.

The controller is used for controlling the rotation direction and the rotation speed of the motor. For example, the controller controls the motor to rotate forward, the motor drives the screw rod to rotate, the screw rod 341 drives the lifting component 342 to ascend from an initial position (for example, the lower end of the screw rod) relative to the storage bin 2, the lifting component 342 drives the lower material barrel 31 to ascend, and after the lower material barrel 31 ascends to a predetermined position, the trigger lever 332 is pressed to drive the lower material door 32 to open, so that the blanking is completed.
