Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0027] In the present application, as Figures 1 to 5As shown, a building construction feeding device is provided, which comprises a vehicle frame 1, wheels 2 arranged at the bottom of the vehicle frame 1, a hopper 3 mounted on the top of the vehicle frame 1, the front end of the hopper 3 is hinged to the vehicle frame 1, the rear end of the hopper 3 is formed with a boss, the feeding device further comprises a locking rod 5, the middle segment of the locking rod 5 is hinged to the rear end of the vehicle frame 1, the upper end of the locking rod 5 is provided with a locking part, the lower end of the locking rod 5 is formed with a push rod part, the locking rod 5 can be rotated to the locking part pressing on the boss, and the locking part is separated from the boss.

[0028] The feeding device of the utility model in use, as shown in the figure, the hopper 3 in the transportation process, the locking part is located on the upper side of the boss, so as to stop the hopper 3 from moving upwards. When unloading is needed, the operator can push or pedal the push rod part of the locking rod 5, so that the locking rod 5 rotates and the locking part is separated from the boss, at which time unloading can be carried out. After the hopper 3 falls back to the vehicle frame 1, the operator can push or pedal the upper end of the locking rod 5, so that the locking rod 5 rotates to the locking part pressing on the boss.

[0029] The feeding device of the utility model realizes the fixation of the hopper 3 by the locking part pressing on the boss, compared with the existing bolt, spring and lock hole form, the utility model structure is simple, and when the cement, sandstone and other materials fall on the boss position, it is easy to clean, not easy to jam and block, and the use stability is high. Moreover, the locking rod 5 of the utility model is located between the two handles at the rear end of the vehicle frame 1, compared with the existing technology, the pull rope and hand brake structure are easy to be damaged, the locking rod 5 of the utility model is shielded by the handle, the vehicle frame 1 and the hopper 3, not easy to knock with external objects, also not easy to be touched by mistake, the use stability is higher. In addition, the locking rod 5 of the utility model can be controlled by pedaling, which is simple and convenient to operate.

[0030] In the utility model, the front-to-back direction is the forward direction of the feeding device. In the illustrated embodiment, the middle segment of the locking rod is welded with a rotating shaft, and the vehicle frame is provided with a shaft sleeve for inserting the rotating shaft.

[0031] In the illustrated embodiment, for the structure of the utility model, further specifically, the lower side of the push rod part of the locking rod 5 is provided with a lower push plate 6. As shown, this can facilitate the operator to pedal the lower push plate 6 to rotate the locking rod 5.

[0032] In the illustrated embodiment, for the structure of the utility model, further specifically, the rear side of the upper end of the locking rod 5 is provided with an upper push plate 7. As shown, this can facilitate the operator to pedal the upper push plate 7 to rotate the locking rod 5.

[0033] In the illustrated embodiment, the upper push plate 7 and the lower push plate 6 are respectively welded on the locking rod 5 to facilitate fixation.

[0034] In the illustrated embodiment, for the structure of the utility model, further specifically speaking, the upper end of the locking rod 5 is bent to form an installation portion 9, the locking portion comprises a pressing rod 8, and the pressing rod 8 is fixed to the inner side of the installation portion 9.

[0035] As shown in the figure, the locking rod 5 is integrally bent to form an installation portion 9, so that the pressing rod 8 can be conveniently and stably fixed, and the pressing rod forms a locking portion. Through the setting of the pressing rod 8, the contact area of the pressing rod 8 and the boss can be increased, so as to further maintain the limiting effect when the locking portion is in contact with the boss. In the illustrated embodiment, the pressing rod 8 is made of cylindrical steel bars.

[0036] In the illustrated embodiment, further optimization is that the top surface of the boss is provided with a rubber layer 403. As shown in the figure, by setting the rubber layer 403, the pressing rod 8 and the rubber layer 403 are deformed in contact, the friction force when the pressing rod 8 is in contact with the boss is increased, so as to prevent the pressing rod 8 from automatically falling off after receiving a jolt impact. At the same time, the rubber layer 403 can also be used to realize the damping effect between the hopper 3 and the pressing rod 8, so as to further reduce the jolt impact of the hopper 3 during the pushing process.

[0037] In the illustrated embodiment, further optimization is that the boss comprises a boss groove 401 connected with the hopper 3, a wooden block 402 installed in the boss groove 401, and the rubber layer 403 covers the top surface of the wooden block 402.

[0038] As shown in the figure, by setting the wooden block 402, when installing the rubber layer 403, the rubber layer 403 can be first installed on the wooden block 402, and then the wooden block 402 is installed in the boss groove 401. When it is necessary to replace the rubber layer 403, the wooden block 402 can be directly taken out, so as to conveniently install and dismount the rubber layer 403. Moreover, by setting the wooden block 402 and the rubber layer 403, the vibration impact transmitted between the boss and the pressing rod 8 can be further weakened, so as to reduce the fatigue cracking of the welding structure of the locking rod 5 under frequent vibration impact.

[0039] In the illustrated embodiment, further optimization of the utility model is that the rubber layer 403 is nailed to the wooden block 402. As shown in the figure, the rubber layer 403 is nailed to the wooden block 402, so that the rubber layer 403 can be conveniently and stably fixed. The bottom of the boss groove 401 is hollow, and when the wooden block 402 is installed in the boss groove 401, a long nail can be inserted into the lower side of the boss through the rubber layer 403 and the wooden block 402, and the bottom of the long nail is bent to fix the wooden block 402.

[0040] In a preferred embodiment, as shown in the figure, a further optimization of the structure of this utility model is that the rear end of the wooden block 402 is provided with an installation groove, the installation groove is fitted with an elastic strip 10, the elastic strip 10 supports the rubber layer 403 at the corresponding position to form an elastic rib, and when the locking part presses against the boss, the elastic rib abuts against the rear end of the locking part.

[0041] like Figure 5 As shown, by setting elastic ribs, the pressure bar 8 and the boss can be further prevented from separating due to the bumps of the truck bed 3, thereby further improving the stability of the pressure bar 8 in holding the boss. By setting the mounting groove, the position of the elastic strip 10 can be kept stable. The elastic strip 10 supports the rubber layer 403, and when the pressure bar separates from the boss, the elastic deformation of the elastic strip 10 can provide space for the pressure bar to move.

[0042] In a preferred embodiment, more specifically regarding the structure of this utility model, when the locking part presses against the boss, the projection of the contact position between the locking part and the boss is offset to the front side of the rotation center of the locking rod 5.

[0043] As shown in the figure, the rotation center of the locking rod 5 is located to the right of the center of the pressure rod 8. This ensures that when the boss is subjected to an upward impact from a bump, the movement trajectory of the pressure rod 8 is diagonally upward to the right. The frictional force generated after the pressure rod 8 contacts the boss can stop the movement of the pressure rod 8. This allows the pressure rod 8 to move slightly to adapt to the impact of the hopper and reduces the possibility of the locking rod 5 being deformed or damaged by the impact. It also limits the rotation range of the locking rod 5 by the frictional force between the pressure rod 8 and the boss.

[0044] In a preferred embodiment, as shown in the figure, the upper section of the locking rod 5 is provided with a connecting rope 11 between it and the frame 1, and the upper end of the locking rod 5 is provided with a counterweight.

[0045] As shown in the figure, the upper push plate 7 and the pressure rod 8 together form a counterweight. This allows the upper end of the locking rod 5 to rotate downwards under the weight of the upper push plate 7 and the pressure rod 8 after the locking part separates from the boss. The connecting rope 11 limits its rotation range, thus keeping the locking part away from the boss and preventing positional interference at the upper end of the locking rod 5 when the truck bed 3 is raised or lowered. Using the connecting rope 11 to limit the locking rod 5 prevents excessive downward rotation of the upper end of the locking rod 5, allowing the operator to easily rotate the pressure rod 8 to the upper side of the boss by stepping on the upper push plate 7.

[0046] It should be noted that, in Figures 1 to 3 The connecting rope 11 is not shown in the drawing. Figure 5The connecting rope 11 is shown in the figure, one end of which is connected to the fixed ring of the frame 1 and the other end is tied to the locking rod 5, the length of the connecting rope 11 is controlled, preferably in the state of the locking rod 5 being turned to the right to the position of 45° to 60° deviated from the vertical plane, so that the operator can conveniently pedal the pushing plate 7 to lock the hopper 3, and also prevent the pressing rod 8 from being turned to the position close to the frame 1 during the process of lifting the frame 1 and turning over the hopper 3 (even if the pressing rod 8 is turned to this position, the locking rod 5 can be turned to the right before the frame 1 is lowered and the hopper 3 is not returned to the original position). Figure 4 The pressing rod 8 is turned to the position close to the frame 1, and the locking rod 5 is turned to the right to the position of 45° to 60° deviated from the vertical plane, so that the operator can conveniently pedal the pushing plate 7 to lock the hopper 3, and also prevent the pressing rod 8 from being turned to the position close to the frame 1 during the process of lifting the frame 1 and turning over the hopper 3 (even if the pressing rod 8 is turned to this position, the locking rod 5 can be turned to the right before the frame 1 is lowered and the hopper 3 is not returned to the original position).

[0047] Each of the embodiments in the specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment mainly explains the difference from other embodiments. Especially, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the related parts can be referred to the part of the method embodiment.

[0048] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the scope of claims of the present application.
