When the hopper cover 47 covers the hopper feed opening 4401, the handle 471 is located on the side of the hopper cover body 470 opposite to the hopper feed opening 4401. In this manner, the worker can open or shield the hopper cover 47 from the hopper feed port 4401 through the handle 471.

The hopper body 44 includes a top wall 443 and a plurality of body side walls 444, the body side walls 444 are sequentially connected end to end, the top wall 443 is disposed at one end of the body side wall 444, the body side walls 444 surround the top wall 443, the top wall 443 and the body side walls 444 jointly enclose the hopper storage silo 442, one ends of the top wall 443 and the body side walls 444 jointly enclose the hopper feed inlet 4401, and the hopper cover 47 is rotatably mounted on the top wall 443. Therefore, the rotary connection structure is simple and convenient to install. The hopper cover 47 can rotate around the top wall 443, and the joint of the hopper cover 47 and the top wall 443 can serve as a rotating shaft for the hopper cover 47 to rotate around the top wall 443. One end of the hopper cover 47 is rotatably disposed on the top wall 443, and when the hopper feed port 4401 needs to be opened, a worker can control the hopper cover 47 to rotate through the handle 471.

The direction of the conveying port 451 toward the feed port 452 is taken as a first direction, the direction of the small bucket discharge port 4412 toward the small bucket feed port 4401 is taken as a second direction, and the included angle theta between the first direction and the second direction is greater than or equal to 90 degrees and less than 150 degrees. Thus, the included angle θ is not too small, so that the structure at the connection portion between the hopper body 44 and the guide tube 45 is prevented from being too bent to cause the raw material to be accumulated at the bent portion, which is beneficial for the guide structure 43 to transport the accumulated raw material to the direction of the discharge opening 452 as much as possible. In addition, the included angle θ is not too large, so that the raw material can be prevented from directly flowing out of the feed opening 452 after being poured into the small bucket feed opening 4401, and the guiding structure 43 can better control the quantity and the flowing speed of the raw material flowing out of the feed opening 452.

In other embodiments, the angle θ formed by the central axis 4403 of the bucket feed inlet 4401 and the central axis 4520 of the feed outlet 452 is greater than 90 ° and less than 150 °. The central axis 4403 of the bucket feed inlet 4401 may be inclined toward the feed opening 452, and the central axis 4403 of the bucket feed inlet 4401 may also be inclined away from the feed opening 452. Therefore, the included angle θ between the small hopper feeding hole 4401 and the feeding hole 452 is set to be larger than 90 ° and smaller than 150 °, so that the included angle θ is not too small, the structure at the connection position of the hopper body 44 and the guide tube 45 is prevented from being bent too much, and the raw material is accumulated at the bent position, and the guide structure 43 is favorable for transporting the accumulated raw material to the direction of the feeding hole 452 as much as possible. In addition, the included angle θ is not too large, so that the raw material can be prevented from directly flowing out of the feed opening 452 after being poured into the small bucket feed opening 4401, and the guiding structure 43 can better control the quantity and the flowing speed of the raw material flowing out of the feed opening 452.

Referring to fig. 5 and 6, in some embodiments, the feed opening 452 protrudes from the body sidewall 444. In this manner, the guide tube 45 can be conveniently communicated with the device to be connected (e.g., the mixing device 70 in fig. 3) and can transport the raw materials into the device to be connected.

In some embodiments, hopper assembly 42 further includes a small hopper valve (not shown) movably disposed at an end of hopper body 44 proximate to hopper outlet 4412 for selectively communicating hopper storage 442 with or without blanking channel 450, and a small material load cell (not shown) disposed within storage 442 and for weighing the weight of the material in storage 442.
