[0020] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0021] Example

[0022] A material transfer device described in this embodiment, such as Figure 1 and Figure 3 As shown, the trolley body is a known technology. The trolley body in this design is mainly composed of wheels 1, hopper 2, handle 5 and legs 7; according to Figure 1 In the middle position, the hopper 2 is a box structure without a top, and its right half is inclined with the left lower and the right higher; there are two wheels 1 arranged front to back, and the wheels 1 are respectively installed on the front and rear side walls of the hopper 2, and the left side of the bottom of the hopper 2 is a support leg 7; the support leg 7 is a rod-shaped structure, the upper end of which is fixed to the bottom of the hopper 2, and the bottom of the support leg 7 is in the same straight line as the bottom of the wheel 1; the handle 5 is fixed to the left side of the hopper 2 and is two in the front and back; the hopper 2 is used to load goods, such as concrete; the support leg 7 is used to maintain stability when loading goods; the handle 5 is used to push and control the movement of the hopper 2 and the wheel 1; when in use, by putting materials, such as concrete, cement, etc., into the hopper 2, and then lifting the two handles 5 with both hands and moving, the handle 5 can drive the bottom of the support leg 7 away from the ground, and at the same time the wheel 1 rolls, thereby driving the hopper 2 and the material inside it to move, thereby achieving the purpose of material transfer;

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, a limit frame 3 is set around the edge of the bucket mouth of the hopper 2 on the trolley body, and the limit frame 3 is a rectangular structure and is connected from top to bottom; because the bucket mouth of the hopper 2 is a rectangular structure, the limit frame 3 is a rectangular structure, and the length and width of the limit frame 3 are designed according to the length and width of the hopper 2, so that the length and width of the limit frame 3 can fit with the outer wall of the bucket mouth of the hopper 2; when the limit frame 3 is fitted with the hopper 2, the limit frame 3 can increase the height of the bucket mouth of the hopper 2, and the limit frame 3 is connected from top to bottom and will not block the feeding port position of the hopper 2; when using the hopper 2 to transport concrete, it is necessary to inject concrete into the hopper 2 During the road construction process, concrete is generally mixed by a mixer truck. Then, the hopper 2 is directly aligned with the discharge port of the mixer truck, and the concrete can be directly poured into the hopper 2. Then, the hopper 2 can be moved to the desired location by operating the handle 5. During the movement of the hopper 2, the concrete in the hopper 2 is easy to spill out because the ground during road construction is uneven. At this time, because the limit frame 3 can increase the height of the hopper 2, the limit frame 3 can prevent the concrete in the hopper 2 from spilling out without changing the transportation capacity, so that the concrete in the hopper 2 can be stably transported to the desired location.

[0024] The above operation is mainly used for transporting liquid materials, and attention should be paid to the injection amount of the liquid materials when injecting the liquid materials, so as not to exceed the original capacity of the hopper 2, so that the limiting frame 3 can stably shield the liquid materials in the hopper 2 and prevent the liquid materials from being poured out; when it is necessary to transport fixed materials such as cement and bricks, the original height of the hopper 2 can be increased through the design of the limiting frame 3, and at this time the filling amount of the solid materials in the hopper 2 can be extended to the position of the limiting frame 3, so that more materials can be transported;

[0025] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the limiting frame 3 is divided into left and right halves, the left and right halves of the limiting frame 3 are hinged together and can be flipped left and right; according to Figure 2 , because the limiting frame 3 is divided, the left and right halves of the limiting frame 3 are both in the form of a "U" and the openings are opposite; in particular, when hinging, the thickness of the left half of the limiting frame 3 is greater than that of the right half, the right side wall of the left half of the limiting frame 3 is provided with a clamping groove 12 for clamping the left end of the right half of the limiting frame 3, the clamping groove 12 is open in front and back, a rotating rod is arranged opposite on the limiting frame 3 in the clamping groove 12, the rotating rod is arranged in the clamping groove 12 through a bearing, a blind hole is arranged in the clamping groove 12 corresponding to each rotating rod, the outer ring of the bearing is fixed in the blind hole, and the rotating rod is fixed with the inner ring of the bearing, so that the left and right halves of the limiting frame 3 can swing, thereby realizing hinging;

[0026] As shown in Figure 1 , the left half of the limiting frame 3 is provided with a fastening screw, the bottom of the left half of the limiting frame 3 is provided with a groove for clamping into the hopper 2, the outer side wall of the left half of the limiting frame 3 is provided with a first threaded hole communicating with the inside of the groove, the hopper 2 is provided with a second threaded hole communicating inside and outside, and the center lines of the first threaded hole and the second threaded hole are located on the same straight line; the fastening screw is threadedly connected in the first threaded hole and the first threaded hole in sequence; the whole of this paragraph constitutes a fixing assembly for fixing the left half of the limiting frame 3 on the hopper 2; the width of the groove is designed according to the width of the hopper 2, so that the groove can be clamped on the hopper 2 just right, and there is no excessive moving gap, so that through the design of the groove clamped on the hopper 2, the left half of the limiting frame 3 can be preliminarily limited on the hopper 2; because the first threaded hole is arranged on the left half of the limiting frame 3 and the second threaded hole is arranged on the hopper 2, the left half of the limiting frame 3 can be fixed on the hopper 2 by threadedly connecting the fastening screw in the first and second threaded holes, thereby ensuring the stability of the limiting frame 3 during use; when the limiting frame 3 needs to be disassembled, the limiting frame 3 can be easily disassembled from the hopper 2 by unscrewing the fastening screw;

[0027] The inner side wall of the right half of the limiting frame 3 is preferably attached to the edge at the hopper mouth of the hopper 2, and in the initial state, the right half of the limiting frame 3 is as shown in the structure in Figure 1 , so that the right half of the limiting frame 3 can only be flipped to the left during the flipping process, and it cannot be flipped to the right because it is limited by the right side wall of the hopper 2. Therefore, the limiting frame 3 can only be flipped from right to left during the flipping process and cannot be flipped below the hopper 2, ensuring the stability of the right half of the limiting frame 3 during use and allowing the right half of the limiting frame 3 to stably shield the concrete poured out of the hopper 2;

[0028] In the specific implementation process, the fastening screws in the fixing assembly can be multiple, and the first threaded hole and the second threaded hole can be multiple groups. The multiple groups of threaded holes and fastening screws are arranged at different positions between the left half of the limiting frame 3 and the hopper 2, such as the front side, the rear side, or the left side wall of the left half of the limiting frame 3. Therefore, through the design of multiple groups, the left half of the limiting frame 3 can be more stably fixed to the hopper 2;

[0029] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the left half of the limiting frame 3 is provided with mounting plates 10, which are two and are respectively fixed to the front and rear side walls of the left half of the limiting frame 3. The front and rear side walls of the right half of the limiting frame 3 are each provided with a rotating shaft 11. One end of each rotating shaft 11 is rotationally connected to the corresponding mounting plate 10. Each rotating shaft 11 is provided with a gear 8, and each mounting plate 10 is provided with a rack 9 that engages with the gear 8. Each rack 9 is connected to a pull rod 4. The overall scheme constitutes a driving assembly for driving the right half of the limiting frame 3 to flip. According to the orientation in Figure 4 , when the mounting plates 10 are installed, the mounting plates 10 have an "L" shape, and the horizontal section of the mounting plates 10 is fixed to the limiting frame 3, so that the vertical section of the mounting plates 10 leaves a certain space with the limiting frame 3. According to the orientation in Figure 2 , when the right half of the limiting frame 3 is installed with the rotating shaft 11, the rotating shaft 11 is two, and the rotating shaft 11 is vertically arranged, with one located in the upper mounting plate 10 and the other located in the lower mounting plate 10. An upper and lower through hole is formed between the top of the limiting frame 3 and the rear upper clamping slot 12, and between the bottom of the limiting frame 3 and the lower clamping slot 12. The lower end of the upper rotating shaft 11 passes through the through hole and is fixed to the clamping rod at the top of the right half of the limiting frame 3, and the upper end of the lower rotating shaft 11 passes through the through hole and is fixed to the clamping rod at the bottom of the right half of the limiting frame 3. Thus, the connection between the right half of the limiting frame 3 and the rotating shaft 11 is achieved. According to Figure 2The upper end of the upper shaft 11 is fixed to the inner ring of the bearing on the upper mounting plate 10, and the lower end of the lower shaft 11 is fixed to the inner ring of the bearing on the lower mounting plate 10, thereby realizing the rotation connection; because the shaft 11 is connected to the clamping rod on the right half of the limit frame 3, when the shaft 11 rotates in the mounting plate 10, it can drive the clamping rod and the right half of the limit frame 3 to rotate; according to Figure 4 In the middle position, when the rack 9 is installed, there is a certain space between the vertical section of the mounting plate 10 and the limit frame 3; the rear rack 9 is located between the mounting plate 10 and the limit frame 3, and fits with the inner top of the mounting plate 10, the rotating shaft 11 is located above the rack 9, and the gear 8 on the rotating shaft 11 is engaged with the rack 9; according to Figure 2 When the gear 8 is in the middle position, one end of the pull rod 4 is fixed to the left wall of the rack 9, and the other end thereof extends to the position of the handle 5. When in use, because the pull rod 4 is connected to the rack 9, the pull rod 4 is pushed to move, and the rack 9 is engaged with the gear 8, so that the gear 8 can be driven to rotate. When the gear 8 rotates, the rotating shaft 11 can be driven to rotate. When the rotating shaft 11 rotates, the right half of the limit frame 3 and the card rod can be driven to rotate. In the initial state, the inner side wall of the right half of the limit frame 3 is attached to the edge of the hopper 2. Later, when the right half of the limit frame 3 is rotated upward, the right half of the bucket mouth of the hopper 2 can be leaked out. At this time, the right half of the limit frame 3 does not block the right half of the hopper 2. At this time, it is convenient to pour out the material in the hopper 2. Therefore, the design that the right half of the limit frame 3 can be turned over is convenient for unloading the material in the hopper 2.

[0030] In a specific implementation process, a protective cover can be placed on the outside of the gear 8, rack 9 and mounting plate 10 in the drive assembly. The protective cover is fixed to the left half of the limit frame 3. Therefore, the design of the protective cover can prevent impurities generated by construction materials from falling onto the gear 8 and rack 9 as much as possible, thereby making the gear 8 and rack 9 more stable during use.

[0031] like Figure 1 and Figure 2 As shown, a snap ring 6 is fixed on each of the pull rods 4, and the snap ring 6 is used to be sleeved on the handle 5 on the trolley body; therefore, when operating the trolley handle 5 to move, the snap ring 6 can be directly pushed to move left and right on it, so that the snap ring 6 can drive the pull rod 4 to move, so that the pull rod 4 is easy to push the rack 9 and the gear 8 to engage, and finally facilitate the flipping of the right half of the limit frame 3;

[0032] like Figure 1 and Figure 2 As shown, the snap ring 6 is made of elastic material, and an opening is cut on the snap ring 6 to facilitate sleeve on the handle 5; the snap ring 6 is made of plastic material; through the elastic design, the snap ring 6 can be opened from the opening, so that the snap ring 6 is conveniently clamped on the handle 5, and then by stopping to break the snap ring 6, the snap ring 6 can be stably clamped on the handle 5 by rebounding through its elasticity. After the snap ring 6 is clamped on the handle 5, a gap is left between the handle 5 and the snap ring 6, so that the snap ring 6 is convenient to move left and right on the handle 5; the snap ring 6 can also be made of aluminum alloy during production, and aluminum alloy also has good elasticity;

[0033] The limit frame 3 is made of aluminum, which has good hardness and is light in weight. Therefore, when the limit frame 3 is fixed on the hopper 2, it can reduce a certain amount of weight, thereby reducing the burden of carrying during use.

[0034] In the specific use process: when the trolley body needs to be used to transport liquid materials such as concrete, first pour concrete into the hopper 2, then push the handle 5 to move the material in the hopper 2 to the desired location, and then pour the concrete out of the hopper 2 according to the Figure 5 In the process of rotating the gear 8, the gear 8 is meshed with the gear 8 and the gear 8 rotates counterclockwise.
