Description

Technical Field

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

[0002] Concrete, also known as "con", is mainly composed of cement, water, sand and stones, and can be formed into hard stone after mixing and compaction. It is a commonly used construction material in the field of building construction. The use of concrete often requires the use of a concrete hopper, which can conveniently guide the concrete to the position where it is needed.

[0003] Nowadays, many concrete hoppers also have a switch structure to facilitate the closing of the concrete output channel when concrete outflow is not required. However, most of the existing concrete hopper switch structures are swing doors. On the one hand, since there is a similar part between the moving direction of the door body and the concrete flow direction, the door body is prone to accidental opening due to force, resulting in low reliability. On the other hand, the door body can only be fully opened or fully closed, and the flow rate of the concrete cannot be adjusted, resulting in poor flexibility. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a concrete hopper switch structure, which can solve one or more of the above problems.

[0005] According to one aspect of the utility model, a concrete hopper switch structure is provided, which includes a power mechanism, a transmission mechanism, a first sprocket mechanism, a second sprocket mechanism, a drag chain, a first door panel, a second door panel, a first connecting block and a second connecting block.

[0006] The power mechanism is connected to the first sprocket mechanism through the transmission mechanism, and the drag chain bypasses the first sprocket mechanism and the second sprocket mechanism.

[0007] An upper chain section and a lower chain section are formed between the first sprocket mechanism and the second sprocket mechanism of the drag chain. The first door panel is connected to the upper chain section through the first connecting block, and the second door panel is connected to the lower chain section through the second connecting block.

[0008] The beneficial effects of the present utility model are as follows: The present utility model can be applied to a concrete hopper. The power mechanism can drive the first sprocket mechanism to act through the transmission mechanism, so that the drag chain can move between the first sprocket mechanism and the second sprocket mechanism. The upper chain section and the lower chain section of the drag chain can move in opposite directions, thereby realizing the in-phase or out-of-phase movement of the first door panel and the second door panel, and thus realizing the closing or opening of the output channel of the concrete hopper. The movement of the first door panel and the second door panel of the present utility model can be a lateral movement, which is not easily misopened by concrete or the like that may fall in the vertical direction. Moreover, the distance between the first door panel and the second door panel can be controlled by controlling the movement of the drag chain, so as to control the output flow of the concrete, and the flexibility is good.

[0009] In some embodiments, the power mechanism includes a hydraulic motor device, a driving wheel, a driven wheel, an output shaft and a driving chain. The driving wheel is connected to the hydraulic motor device, the driven wheel is connected to the output shaft, and the driving chain bypasses the driving wheel and the driven wheel. The hydraulic motor device can drive the driving wheel to rotate, then the driving wheel can drive the driven wheel to rotate through the driving chain, so that the output shaft rotates, and the rotation of the output shaft can drive the first sprocket mechanism to act through the transmission mechanism.

[0010] In some embodiments, the power mechanism includes a handwheel, a wheel shaft and a bevel gear set. The handwheel is connected to the wheel shaft, and the wheel shaft is connected to the output shaft through the bevel gear set. The user can rotate the handwheel to make the output shaft rotate, which is convenient for the user to manually drive the opening and closing of the first door panel and the second door panel.

The unit transmission mechanism includes a rotating shaft, a first transmission wheel and a second transmission wheel. Both the first transmission wheel and the second transmission wheel are sleeved on the rotating shaft.

The number of unit transmission mechanisms can be adapted to the use of different concrete hopper sizes, and the flexibility is strong.

[0012] In some embodiments, the unit transmission mechanism includes a bushing, and the rotating shaft is rotatably installed on the bushing. The setting of the bushing can facilitate the installation and fixation of the unit transmission mechanism on the concrete hopper.

[0013] In some embodiments, the first sprocket mechanism includes a first shaft, a first sprocket and a first shaft seat. The first shaft is installed on the first shaft seat, and the first sprocket is installed on the first shaft.

[0019] The present utility model will be further described in detail below with reference to the drawings.

[0020] Refer to Figure 1 、 Figure 2 and Figure 3 A concrete hopper switch structure of the present utility model includes a power mechanism 1, a transmission mechanism 2, a first sprocket mechanism 3, a second sprocket mechanism 4, a drag chain 5, a first door panel 6, a second door panel 7, a first connecting block 8 and a second connecting block 9.

[0021] The power mechanism 1 includes a hydraulic motor device 11, a driving wheel, a driven wheel 13, an output shaft 14 and a driving chain 15. The output shaft of the hydraulic motor device 11 is connected to the driving wheel, so that the hydraulic motor device 11 can drive the driving wheel to rotate. The driven wheel 13 is fixedly sleeved on the output shaft 14 for connection with the output shaft 14. Then, the output shaft 14 can rotate with the rotation of the driven wheel 13, and the driving chain 15 can bypass the driving wheel and the driven wheel 13. Thus, the rotation of the driving wheel can drive the driven wheel 13 to rotate through the driving chain 15.

[0022] The power mechanism 1 further includes a handwheel 16, a wheel shaft 17, and a bevel gear set 18. One end of the handwheel 16 and the wheel shaft 17 are fixedly connected by bolts, so that the rotation of the handwheel 16 can drive the rotation of the wheel shaft 17. The bevel gear set 18 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the other end of the wheel shaft 17, while the second bevel gear 18 is fixedly sleeved on the wheel shaft 17, and the first bevel gear and the second bevel gear are meshed, that is, the wheel shaft 17 is connected to the output shaft through the bevel gear set 18.

[0023] The transmission mechanism 2 includes a transmission chain 21 and unit transmission mechanisms 22. There can be multiple unit transmission mechanisms 22. In this embodiment, the unit transmission mechanisms 22 are preferably three. The unit transmission mechanism 22 includes a rotating shaft 221, a first transmission wheel 222, and a second transmission wheel 223. In each unit transmission mechanism 22, the first transmission wheel 222 and the second transmission wheel 223 are both fixedly sleeved on the same rotating shaft 221, and the first transmission wheel 222 of the unit transmission mechanism 22 is connected to the second transmission wheel 223 of the adjacent unit transmission mechanism 22 through an independent transmission chain 21.

[0024] The unit transmission mechanism 22 can further include a bushing 224. In each unit transmission mechanism 22, the bushing 224 is sleeved on the rotating shaft 221 through a bearing, so that the rotating shaft 221 is rotatably installed on the bushing 224, and the bushing 224 can be connected to an external concrete hopper through bolts, thereby connecting the unit transmission mechanism 22 to the external concrete hopper.

[0025] The first sprocket mechanism 3 includes a first shaft 31, a first sprocket 32, and a first shaft seat 33. The first shaft 31 is rotatably installed on the first shaft seat 33 through a bearing, and the first sprocket 32 is fixedly sleeved on the first shaft 31. At the same time, the first shaft 31 is also provided with a driving wheel, and the driving wheel is connected to the second transmission wheel 223 on one of the unit transmission mechanisms 22 at the end through a chain, so that the power mechanism 1 is connected to the first sprocket mechanism 3 through the transmission mechanism 22.

[0026] The second sprocket mechanism 4 includes a second shaft 41, a second sprocket 42, and a second shaft seat 43. The second shaft 41 is rotatably installed on the second shaft seat 43 through a bearing, and the second sprocket 42 is fixedly sleeved on the second shaft 41.

[0027] The drag chain 5 bypasses the first sprocket 32 of the first sprocket mechanism 3 and bypasses the second sprocket 42 of the second sprocket mechanism 4, and an upper chain segment 51 and a lower chain segment 52 are formed between the first sprocket mechanism 3 and the second sprocket mechanism 4 for the drag chain 5.

[0028] The first connecting block 8 is fixedly connected to the upper chain segment 51 of the drag chain 5 through bolts, and the first door panel 6 is also fixedly connected to the bolt, so that the first door panel 6 can be connected to the upper chain segment 51 through the first connecting block 8.

[0029] The second connecting block 9 is fixedly connected to the lower chain section 52 of the drag chain 5 by bolts, and the second door panel 7 is also fixedly connected to the bolt, so that the second door panel 7 can be connected to the lower chain section 52 through the second connecting block 9.

[0030] When the utility model is in use, the bushings 224 of the respective unit transmission mechanisms 22 of the transmission mechanism 2 can be fixedly connected to the main body of the external concrete hopper by bolts respectively, and the first door panel 6 and the second door panel 7 can be arranged at the discharge port of the concrete hopper. When the opposite sides of the first door panel 6 and the second door panel 7 can abut against each other, the first door panel 6 and the second door panel 7 can close the discharge port.

[0031] The user can drive the hydraulic motor device 11, so that the hydraulic motor device 11 drives the driving wheel to rotate. The driving wheel can drive the driven wheel 13 to rotate through the driving chain 15, then the output shaft 14 can rotate with the rotation of the driven wheel 13. The rotation of the output shaft 14 can drive the first shaft 31 to rotate through the transmission mechanism 2. With the rotation of the first shaft 31, the drag chain 5 can move accordingly. The first door panel 6 connected to the drag chain 5 through the first connecting block 8 and the second door panel 7 connected to the drag chain 5 through the second connecting block 9 can move with the movement of the drag chain. The transmission of the transmission mechanism 2 can rotate the first transmission wheel 222 on a unit transmission mechanism 22, so that the connected rotating shaft 221 rotates, and then the second transmission wheel 223 arranged on the rotating shaft 221 also rotates accordingly. The rotation of the second transmission wheel 223 can drive the first transmission wheel 222 on another adjacent unit transmission mechanism through the transmission chain 21, so as to realize the transmission of power. The last unit transmission mechanism 22 can transmit the power to the first shaft 31 to make the first shaft 31 rotate.

[0032] During the movement of the drag chain 5, since the moving directions of the upper chain section 51 and the lower chain section 52 of the drag chain 5 are opposite, by changing the movement direction of the drag chain 5, that is, changing the rotation direction of the driving wheel driven by the hydraulic motor device 11, the first door panel 6 and the second door panel 7 can move towards or away from each other, so as to realize the closing or opening of the discharge port of the concrete hopper, and the flow rate of the concrete material flowing out of the discharge port of the concrete hopper can be effectively adjusted by controlling the distance between the first door panel 6 and the second door panel 7.

[0033] In addition, the user can also manually rotate the handwheel 16, so that the handwheel 16 drives the wheel shaft 17 to rotate. The wheel shaft 17 can drive the output shaft 14 to rotate through the bevel gear set 18. With the rotation of the transmission shaft 14, the rotation of the first shaft 31 can finally be realized, that is, the drag chain 5 is moved, so that the first door panel 6 and the second door panel 7 are opened or closed. Thus, by using the utility model, the user can manually open and close the discharge port of the concrete hopper using the utility model.

[0034] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
