FIG. 3 is a partial cross-sectional view corresponding to section A-A in FIG. 2;

labeled as: the hopper comprises a hopper body 1, front wheels 2, rear wheels 3, a wheel shaft 4, rollers 5, grooves 6, a slide way 61, a support 7, hinges 8, bolts 9, spring gaskets 10, a bottom plate 11, side plates 12 on two sides, a front end baffle 13, a rear end baffle 14 and a handle 15.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

It should be noted that, if there are directional indication terms, such as the terms of direction and orientation, above, below, left, right, front and back, in the present invention, for facilitating the description of the relative positional relationship between the components, the absolute position that is not the positional relationship between the related components and the components is specifically referred to, and is only used for explaining the relative positional relationship and the motion situation between the components in a specific posture, and if the specific posture is changed, the directional indication is changed accordingly. When the present invention relates to a number, such as "a plurality", "several", etc., two or more than two are specifically referred to.

As shown in fig. 1 to 3, the cart according to the present invention includes a hopper body 1, front wheels 2 and rear wheels 3, the front wheels 2 are disposed at a front portion of a bottom of the hopper body 1, the rear wheels 3 are disposed at a rear portion of the bottom of the hopper body 1, the rear wheels 3 include a wheel shaft 4, rollers 5 are respectively disposed at two ends of the wheel shaft 4, at least two grooves 6 are disposed at the rear portion of the bottom of the hopper body 1, and the grooves 6 are disposed in parallel at intervals along a front-rear direction of the hopper body 1, and the wheel shaft 4 can be switched in the grooves 6 to achieve a snap fit.

According to the cart, due to the arrangement of the corresponding structures of the plurality of grooves 6, after the matching of the different grooves 6 and the wheel shaft 4 is adjusted, the supporting position of the hopper main body 1 can be adjusted by the rear wheels 3, and further, the different grooves 6 can be selectively arranged according to actual conditions for matching, so that the aim of saving labor can be fulfilled. For example, in downhill pushing, the wheel axle 4 can be arranged to cooperate with the recess 6 relatively forward; the wheel axle 4 can be arranged to cooperate with the recess 6 relatively in the middle when pushing on flat ground, and the wheel axle 4 can be arranged to cooperate with the recess 6 relatively behind when pushing on an uphill.

More specifically, referring to fig. 1, two grooves 6 may be provided in the present invention, and the two grooves 6 are distributed in parallel at intervals along the front-rear direction of the cart.

More specifically, in the case of two grooves 6, only one groove may be provided with a slideway 61 for communication between the two grooves 6, so that when the switching wheel axle 4 is required to be matched with different grooves 6, the wheel axle 4 can move along the slideway 61, thereby playing a role in limiting and guiding the wheel axle 4 in the switching process and facilitating the switching of the wheel axle 4.

More specifically, the front wheels 2 of the present invention are mainly used for the purpose of auxiliary support and steering, and the front wheels 2 of the present invention can be preferably arranged as universal wheels, so that steering can be adjusted more conveniently.

More specifically, referring to fig. 1, the present invention further provides that a support 7 is fixedly installed at each of two ends of the wheel axle 4 in the rear wheel 3, the support is a triangular support or a cross-shaped support 7, and a roller 5 is respectively installed at each of the corresponding ends of the support 7; the specific structure shown in fig. 1 is a supporting structure adopting a cross-shaped support 7, and four ends of the cross are respectively provided with a roller 5 capable of freely rolling, so that when people need to go up and down stairs, the function of climbing stairs can be realized by rotating the rollers 5 on the support 7 integrally around the axis of the wheel shaft 4; when the trolley runs on a flat ground, the trolley can move through the rolling action of the two rollers 5 at the bottom.

More specifically, a spring washer 10 may be provided in each groove 6 in the present invention; this has the advantage that a certain resilient damping action is achieved by the spring washer 10 during the pushing operation.

More specifically, the hopper body 1 of the present invention includes a structure with an open top, which is enclosed by a bottom plate 11, side plates 12 on both sides, a front end baffle 13 and a rear end baffle 14, and a handle 15 extending rearward is provided at the rear end of the hopper body 1, and the handle 15 is used for holding when pushing the cart. In the invention, in order to facilitate the unloading of the cart, the bottom edge of the front end baffle 13 is further arranged on the bottom plate 11 of the hopper main body 1 through a hinge 8, and two sides of the top edge of the front end baffle 13 are respectively matched with the side plates 12 on the corresponding sides through arranged bolts 9. Therefore, when the material needs to be unloaded, the front end baffle 13 can be opened for unloading only by manually pulling out the corresponding forehead bolt 9. Similarly, the same principle can be adopted for the rear end baffle 14 in the invention, that is, the bottom edge of the rear end baffle 14 is arranged on the bottom plate 11 of the hopper main body 1 through the hinge 8, and two sides of the top edge of the rear end baffle 14 are respectively matched with the side plates 12 on the corresponding sides through the arranged bolts 9.
