Of course, the outlet 3 is oriented generally horizontally or slightly downwardly, rather than being disposed at the bottom of the receiving hopper and facing downwardly.
The part of the inner surface of the hopper wall 1 facing the discharge opening 3 is provided with a plurality of wear strips 2, which wear strips 2 extend transversely, which means that the overall extension direction of the wear strips 2 is substantially transverse, but does not represent that the wear strips 2 are strictly rectilinear, and that there may be a certain extension in other directions, such as vertical, or that the extension varies due to adaptation to the arc shape of the hopper wall 1.
In addition, the wear-resistant strip 2 is made of wear-resistant materials, so that the abrasion of aggregate in the receiving hopper to the wear-resistant strip 2 is relieved, and the replacement period is prolonged.
The wear-resistant strip 2 is a structure protruding on the inner surface of the hopper wall 1, an included angle is formed between the upper side of the wear-resistant strip 2 and the hopper wall 1, so that the upper side of the wear-resistant strip 2 can accumulate aggregate with a certain height to cover the hopper wall 1 with a certain height; and a plurality of wear strips 2 are arranged at intervals in the vertical direction, and aggregate with a certain height can be accumulated respectively, so that the inner surface of the hopper wall 1 opposite to the discharge hole 3 is covered by the aggregate, the aggregate flowing in the hopper wall 1 can not be in direct contact with the hopper wall 1, the hopper wall 1 is protected from friction, and the service life is prolonged.
According to one embodiment of the invention, the wear strip 2 extends horizontally. Referring to fig. 1 and 2, the wear strip 2 is generally horizontally extending linear when viewed from a horizontal perspective. The plurality of wear strips 2 may be arranged at equal intervals.
According to another embodiment of the invention, the wear strip 2 is circular arc-shaped and the height of the middle part of the wear strip 2 is low. As shown in fig. 3, the middle portion of the wear strip 2 takes a curved shape with both ends bent upward, so that aggregates can be more easily accumulated in the middle portion of the wear strip 2, ensuring that a sufficient amount of aggregates is accumulated on the wear strip 2 to protect the inner surface of the hopper wall 1.

As shown in fig. 4, the wear strip 2 is V-shaped, the sharp corner in the middle of the wear strip protrudes downwards, and the two ends of the wear strip are tilted upwards, so that aggregates can be more easily accumulated in the middle part of the wear strip 2, and a sufficient amount of aggregates can be accumulated on the wear strip 2 to protect the inner surface of the hopper wall 1.
According to a further embodiment of the invention, a plurality of said wear strips 2 are formed in a grid structure crossing each other. As shown in fig. 5, the grid structure formed by the intersecting wear strips 2 can better bind the aggregate in each grid so that the aggregate is more tightly covered on the inner surface of the hopper wall 1 in each grid, protecting the hopper wall 1.
