When the concrete in the mixing drum needs to be discharged, a discharging device is required to discharge the concrete from the mixing drum. Some of the feeding and discharging devices currently used in mixer trucks do not have the function of discharging. The feeding and discharging devices use different structures, which makes the structure complicated. Some discharging devices are inconvenient, which easily causes the concrete to scatter outside the mixing drum during the discharging process. Summary of the invention

[0010] In this technical solution, the two ends of the first connecting rod are rotatably connected to the hopper and the tail wing through a rotating member, for example, the rotating member can be a pin. When the end of the first connecting rod connected to the tail wing rotates, during the rotation of the first connecting rod, the hopper will also rotate synchronously with the end of the first connecting rod away from the tail wing, so as to ensure that the hopper can switch between the feeding position and the discharging position.

[0047] Refer to the following Figures 3 to 8 The material loading and unloading device 100 and the mixer truck 10 according to some embodiments of the present invention are described.

[0048] Example 1: Figure 3 and Figure 5As shown, this embodiment provides a feed and discharge device 100, which is used for feeding at a feed position 102 and discharging at a discharging position 104. The feed and discharge device 100 includes: a frame 110, a hopper 120 and a connecting mechanism 130, wherein the hopper 120 is rotatably connected to the frame 110; and a connecting mechanism 130, which is connected between the frame 110 and the hopper 120. The connecting mechanism 130 can switch the hopper 120 between the feed position 102 and the discharging position 104, so that the hopper 120 completes feeding or discharging.

[0049] In this embodiment, the frame includes a tail 112 and a backstage 114. The backstage 114 mainly plays a supporting role. The tail 112 is connected to the backstage 114.

The hopper 120 can be rotatably connected to the tail 112 through a connecting mechanism 130, so that the hopper 120 can rotate around its own rotating part and can rotate as a whole around the rotating part on the tail 112, so that the hopper 120 can be switched between the feeding position 102 and the discharging position 104. That is, the functions of feeding and discharging can be completed by one device, which simplifies the structure and reduces the cost and weight.

[0050] Example 2: Figure 3 As shown, this embodiment provides a feeding and discharging device 100. In addition to the technical features of the above embodiment, this embodiment also includes the following technical features:

[0052] In this embodiment, the two ends of the first connecting rod 132 are rotatably connected to the hopper 120 and the tail wing 112 through a rotating member, for example, the rotating member can be a pin. When the end of the first connecting rod 132 connected to the tail wing 112 rotates, the hopper 120 will also rotate synchronously with the end of the first connecting rod 132 away from the tail wing 112 during the rotation of the first connecting rod 132, so that the hopper 120 can switch between the feeding position 102 and the discharging position 104. The first connecting rod 132 is provided with two and symmetrically arranged, which can ensure the stability of the hopper 120 during the rotation process. When the hopper 120 rotates to the feeding position 102 or the discharging position 104, the hopper 120 is rotatably connected to the end of the first connecting rod 132 away from the tail wing 112, so that the angle of the hopper 120 can be adjusted to be able to dock with the feeding and discharging device such as the barrel, which can ensure the smooth feeding and discharging.
