Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a concrete hopper. Background Art

[0002] Concrete is an engineering composite material mixed with cementitious materials, aggregates, water, etc. in a certain proportion and stirred. It has high compressive strength and excellent durability, and is widely used in buildings such as roads, houses, and bridges. When discharging concrete, a hopper is often used to guide the flow of concrete to ensure that the concrete can flow to the required position.

[0026] The surrounding block 2 is fixedly installed on the bracket 3 by welding, and an accommodating cavity is provided in the surrounding block 2. The bottom of the hopper 1 is fixedly installed on the bracket 3 by welding. The hopper 1 is embedded in the accommodating cavity of the surrounding block 2, and the outer periphery of the hopper 1 is fixedly connected to the side wall of the accommodating cavity by welding, so that the hopper 1 is fixed within the surrounding block 2.

[0027] The hopper 1 and the surrounding block 2 after being arranged jointly enclose a discharging cavity 11. A discharging port 12 is provided at the bottom of the hopper 1, and the discharging port 12 is communicated with the material cavity 11.

[0028] The switch door mechanism 6 includes a drag chain 61, a first sprocket mechanism 62, a second sprocket mechanism 63, a chain drive mechanism 64, an output shaft 65 and a hydraulic motor device 66. The first sprocket mechanism 62 includes a first sprocket 621, a first rotating shaft 622 and a first shaft seat 623. The first shaft seat 623 is fixedly installed on the bracket 3 by bolts, and the first rotating shaft 622 is rotatably installed on the first shaft seat 623 through bearings. The first sprocket 621 is fixedly sleeved on the first rotating shaft 622. At the same time, the second sprocket mechanism 63 includes a second sprocket 631, a second rotating shaft 632 and a second shaft seat 633. The second shaft seat 633 is fixedly installed on the bracket 3 by bolts, and the second rotating shaft 632 is rotatably installed on the second shaft seat 633 through bearings. The second sprocket 631 is fixedly sleeved on the second rotating shaft 632.

[0029] The drag chain 61 bypasses the first sprocket 621 of the first sprocket mechanism 62 and the second sprocket 631 of the second sprocket mechanism 63. Then, an upper chain segment 611 and a lower chain segment 612 are formed between the first sprocket mechanism 62 and the second sprocket mechanism 63. The first door panel 4 is fixedly connected to the upper chain segment 611 through a connecting block, and the second door panel 5 is fixedly connected to the lower chain segment 612 through a connecting block. Then, the first door panel 4 can move along with the movement of the upper chain segment 611, and the second door panel 5 can move along with the movement of the lower chain segment 612.

[0030] The hydraulic motor device 66 is fixedly installed on the bracket 3 by bolts, and the output shaft 65 is rotatably connected to the outer periphery of the hopper 1 through a shaft seat. The hydraulic motor device 66 is connected to the output shaft 65 through a chain drive device, so that the hydraulic motor device 66 can drive the output shaft 65 to rotate.

[0031] In order to facilitate the energy supply for the hydraulic motor device 66, the switch door mechanism 6 can further include a power source 67, a hydraulic pump 68 and a boss 69. The boss 69 is fixedly connected to the side part of the surrounding block 2 by welding. The power source 67 and the hydraulic pump 68 are both connected to the boss 69 by bolts. The power source 67 is electrically connected to the motor of the hydraulic pump 68 through a wire. The hydraulic pump 68 is connected with an oil tank, and the hydraulic pump 68 is connected to the hydraulic motor device 66. The hydraulic pump 68 can supply liquid to the hydraulic motor device 66.

[0032] For the convenience of manual operation, the door opening and closing mechanism 6 can further include a handwheel 610, a wheel shaft 620 and a bevel gear set 630. The handwheel 610 is fixedly sleeved on one end of the wheel shaft 620 to be fixedly connected with the wheel shaft 620, and the other end of the wheel shaft 620 is connected to the output shaft 65 through the bevel gear set 630. Then, the user can rotate the handwheel 610 to rotate the wheel shaft 620 to drive the output shaft 65 to rotate.

[0033] The chain transmission mechanism 64 includes a transmission chain 641 and a unit transmission mechanism 642. There can be multiple unit transmission mechanisms 642. In this embodiment, the unit transmission mechanism 642 is preferably three. The unit transmission mechanism 642 includes a rotating shaft 6421, a first transmission wheel 6422, a second transmission wheel 6423 and a shaft seat 6424. Both the first transmission wheel 6422 and the second transmission wheel 6423 are fixedly sleeved on the rotating shaft 6421. The rotating shaft 6421 is installed on the shaft seat 6424 through a bearing. The shaft seats 6424 of all the unit transmission mechanisms 642 are fixedly connected to the periphery of the hopper 1 through bolts, and the first transmission wheel 6422 of each unit transmission mechanism 642 is connected to the second transmission wheel 6423 of the adjacent unit transmission mechanism 642 through the transmission chain 641.

[0034] For the unit transmission mechanisms 642 at both ends of the chain transmission mechanism 64, the second transmission wheel 6423 of one unit transmission mechanism 642 is connected to the output shaft 65 through a chain, and an input wheel is fixedly sleeved on the first rotating shaft 622 of the first sprocket mechanism 62. The first transmission wheel 6422 of the other unit transmission mechanism 642 is connected to the input wheel through a chain, so that the output shaft 65 is connected to the first sprocket mechanism 62 through the chain transmission mechanism 64.

[0035] After being arranged, the first door panel 4 and the second door panel 5 are located near the discharge port 12 and are both connected to the door opening and closing mechanism 6. Since the moving directions of the upper chain segment 611 and the lower chain segment 612 of the drag chain are opposite, the door opening and closing mechanism 6 can drive the first door panel 4 and the second door panel 5 to move towards or away from each other simultaneously. When the first door panel 4 and the second door panel 5 move towards each other and abut against each other, they can close the discharge port 12. When the first door panel 4 and the second door panel 5 move away from each other, the first door panel 4 and the second door panel 5 can be separated from each other.

[0036] This concrete hopper can further include a filter plate 7. The surrounding block 2 is provided with a supporting block 21 in the material cavity 11. The supporting block 21 is arranged in the material cavity, and the filter plate 7 is erected on the supporting block 21.

[0037] This concrete hopper can further include a cover 8. The cover 8 is detachably connected to the bracket 3 through a buckle. An opening is provided at the top of the material cavity 11. After being connected, the cover 8 can cover the opening to close the material cavity 11, and a plurality of observation doors 81 are provided on the cover 8.

[0038] This concrete hopper may further include a ladder 9 which is fixedly connected to the surrounding block 3 by bolts.

[0039] When in use, when it is necessary to transport concrete, the switch door mechanism 6 can be activated to close the discharge port 12. Specifically, the hydraulic motor device 66 can be activated, and correspondingly, the hydraulic pump 68 and the power supply 67 can be activated. The power supply 67 can supply energy to the hydraulic pump 68, the hydraulic pump 68 can supply liquid to the hydraulic motor device 66, and the hydraulic motor device 66 can drive the output shaft 65 to rotate through the chain drive device. The rotation of the output shaft 65 can drive the first sprocket mechanism 62 to act through the chain drive mechanism 64, so that the drag chain 61 can move between the first sprocket mechanism 62 and the second sprocket mechanism 63. Since the first door panel 4 and the second door panel 5 are respectively arranged on the upper chain segment 611 and the lower chain segment 612 of the drag chain 61, with the movement of the drag chain 61, the first door panel 4 and the second door panel 5 can move towards or away from each other. Driving the first door panel 4 and the second door panel 5 to move towards each other makes the first door panel 4 and the second door panel 5 abut against each other to close and cover the discharge port 12.

[0040] In addition, the output shaft 65 can also be driven to rotate by turning the handwheel 610 to manually drive the movement of the first door panel 4 and the second door panel 5.

[0041] After that, the cover 8 is opened, and external concrete can be input into the material cavity 11. Due to the blockage of the first door panel 4 and the second door panel 5, the concrete will not flow out from the discharge port, which facilitates the transportation of concrete. And the cover 8 can be covered again to further prevent the concrete from flowing out of this concrete hopper during transportation.

[0042] When it is necessary to output concrete, the switch door mechanism 6 can be activated to open the discharge port 12. Only by correspondingly changing the working direction of the hydraulic motor device 66 or the rotation direction of the handwheel 610, the first door panel 4 and the second door panel 5 can move away from each other and separate, so that the discharge port 12 can be exposed and the concrete in the material cavity 11 can be effectively output.

[0043] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
