Description

Technical Field

[0001] This utility model relates to the technical field of hopper lifting devices, and in particular to a hopper lifting device for a mixing plant. Background Technology

[0002] As an indispensable infrastructure in the modern construction industry, batching plants undertake the crucial task of efficiently and precisely preparing building materials such as concrete.

[0003] Currently, among the existing hopper lifting equipment for mixing plants, such as the patent with authorization announcement number CN220840868U, this utility model discloses a lifting device for a concrete mixing plant, including: a fixed frame and a hopper. The top of the fixed frame is fixed with a drive box for sliding the hopper. The bottom end of the hopper is hinged with a sealing baffle. The sealing baffle is connected to the hopper through a tension assembly. The top end of the sealing baffle is hinged with a pull rod. The top end of the pull rod is hinged with a guide rod located inside the hopper. The top end of the inner wall of the hopper is fixed with a support plate for the guide rod to pass through.

[0004] However, during use, it was found that the device had poor assist effect when lifting the hopper, which increased operating energy consumption and motor load. Furthermore, the device's reliability in sealing materials through the baffle was poor, which reduced the safety of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mixing plant hopper lifting device that improves the storage reliability of concrete during transportation and avoids leakage by increasing the load on the power unit to offset the weight of the hopper, thereby reducing the operating energy consumption.

[0006] This utility model discloses a hopper lifting device for a mixing plant, comprising a base and a guide frame, with the guide frame mounted on the top of the base; it also includes a traction device, a power device, a support seat, a bracket, and a hopper body. The support seat is slidably mounted on the guide frame via the traction device, the bracket is mounted on the outer wall of the support seat, and the hopper body is eccentrically rotated and mounted on the outer wall of the bracket. The power device is mounted on the support seat, serving to support and limit the hopper body and to provide power for its rotation. When concrete to be lifted and transported is placed inside the hopper body, the weight of the concrete presses down on the hopper body, causing the hopper body to rotate eccentrically and press down on the power device, thus stabilizing the hopper body. The traction device drives the support seat to slide upward, causing the support seat to lift and transport the hopper body upward. When concrete needs to be discharged, the power device lifts one side of the hopper body upward, causing the hopper body to rotate and dump the concrete outward, improving the reliability of concrete storage during transport and preventing leakage. By increasing the load on the power device to offset the weight of the hopper body, the operating energy consumption of the device is reduced.

[0007] Preferably, the power unit includes a guide groove, a slider, a connector, a lead screw, a motor, and a connecting rope. The guide groove is installed on the outer wall of the support, the slider is slidably installed on the guide groove, the connector is installed on the outer wall of the bucket body, the connecting rope is disposed between the slider and the connector, the lead screw is rotatably installed on the inner wall of the guide groove, the slider is fitted onto the lead screw, the motor is installed on the outer wall of the guide groove, and the output end of the motor is connected to the lead screw. The bucket body rotates eccentrically under gravity, pressing the connecting rope through the connector, thereby supporting the bucket body with the slider. When the motor drives the lead screw to rotate, the lead screw drives the slider to move upward, thereby causing the slider to pull the bucket body to rotate through the connecting rope, improving the convenience of dumping and discharging concrete from the bucket body.

[0008] Preferably, the traction device includes guide wheels, a traction rope, a counterweight, and a winch. Multiple sets of guide wheels are installed on the top of the guide frame. The end of the traction rope is connected to the top of the support base. The other end of the traction rope is connected to the outer wall of the winch through the guide support of multiple sets of guide wheels. The counterweight is set on the outer wall of the traction rope. The winch winds up or unwinds the traction rope, thereby causing the traction rope to pull the support base up and down, which in turn causes the support base to drive the bucket to lift and transport. By setting the counterweight, the load on the traction rope is increased, thereby offsetting the weight of the bucket, improving the operating efficiency of the device, and reducing the energy consumption and load of the winch.

[0009] Preferably, it also includes a guide rail, which is installed on the outer wall of the base and the guide frame, and the counterweight is slidably installed on the guide rail; by setting the guide rail, the stability of the counterweight movement is improved.

[0010] Preferably, it also includes reinforcing ribs, which are disposed between the base and the guide frame; by providing reinforcing ribs, the structural strength between the base and the guide frame is improved.

[0011] Preferably, it also includes an inclined surface, which is set on the bucket body; by setting the inclined surface, the convenience of guiding and discharging concrete inside the bucket body is improved.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The concrete to be lifted and transported is placed inside the bucket. Due to the weight of the concrete, the bucket is pressed down, causing the bucket to rotate eccentrically and press down on the power device, thereby keeping the bucket stable. The traction device drives the support seat to slide upward, and the support seat drives the bucket to lift and transport upward. When it is necessary to discharge the concrete, the power device lifts one side of the bucket upward, so that the bucket rotates and the concrete is poured out and discharged. This improves the storage reliability of concrete during transportation and avoids leakage. By increasing the load on the power device to offset the weight of the bucket, the operating energy consumption of the device is reduced. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 5 As shown, the present invention provides a mixing plant hopper lifting device, including a base 1 and a guide frame 2, the guide frame 2 being installed on the top of the base 1; it also includes a traction device, a power device, a support base 3, a bracket 4, and a bucket body 5. The support base 3 is slidably mounted on the guide frame 2 via the traction device, the bracket 4 is mounted on the outer wall of the support base 3, and the bucket body 5 is eccentrically rotated and mounted on the outer wall of the bracket 4. The support base 3 is provided with a power device, which is used to support and limit the bucket body 5, and also to provide power for the rotation of the bucket body 5.

[0022] like Figure 2 As shown, the power unit includes a guide groove 6, a slider 7, a connector 8, a lead screw 9, a motor 10, and a connecting rope 18. The guide groove 6 is installed on the outer wall of the bracket 4, the slider 7 is slidably installed on the guide groove 6, the connector 8 is installed on the outer wall of the bucket body 5, the connecting rope 18 is arranged between the slider 7 and the connector 8, the lead screw 9 is rotatably installed on the inner wall of the guide groove 6, the slider 7 is fitted on the lead screw 9, the motor 10 is installed on the outer wall of the guide groove 6, and the output end of the motor 10 is connected to the lead screw 9.

[0023] In this embodiment, the concrete to be lifted and transported is placed inside the bucket 5. Due to the weight of the concrete, the bucket 5 is pressed down, causing the bucket 5 to be subjected to eccentric rotation and press down on the power device, thereby keeping the bucket 5 stable. The traction device drives the support seat 3 to slide upward, so that the support seat 3 drives the bucket 5 to be lifted and transported upward. When it is necessary to discharge the concrete, the power device lifts one side of the bucket 5 upward, so that the bucket 5 rotates and pours the concrete outward, improving the storage reliability of the concrete during transportation and avoiding leakage. By increasing the load on the power device to offset the weight of the bucket 5, the operating energy consumption of the device is reduced.

[0024] Example 2

[0025] Based on Example 1, such as Figure 3 As shown, this utility model discloses a mixing plant hopper lifting device. The traction device includes guide wheels 11, traction rope 12, counterweight 13 and winch 14. Multiple sets of guide wheels 11 are installed on the top of the guide frame 2. The end of the traction rope 12 is connected to the top of the support seat 3. The other end of the traction rope 12 is connected to the outer wall of the winch 14 through the guide support of multiple sets of guide wheels 11. The counterweight 13 is set on the outer wall of the traction rope 12.

[0026] like Figure 4 As shown, it also includes a guide rail 15, which is installed on the outer side wall of the base 1 and the guide frame 2, and the counterweight 13 is slidably installed on the guide rail 15.

[0028] like Figure 4 As shown, it also includes a ramp 17, which is set on the bucket body 5;

[0029] In this embodiment, the bucket 5 rotates eccentrically under gravity, pressing the connecting rope 18 through the connector 8, thereby supporting the bucket 5 with the slider 7. When the motor 10 drives the lead screw 9 to rotate, the lead screw 9 drives the slider 7 to move upward, thereby causing the slider 7 to pull the bucket 5 to flip through the connecting rope 18, improving the convenience of dumping and discharging concrete in the bucket 5. The winch 14 winds up or unwinds the traction rope 12, thereby causing the traction rope 12 to pull the support seat 3 to slide up and down, which in turn causes the support seat 3 to lift and transport the bucket 5. By setting a counterweight 13 to increase the load on the traction rope 12, the counterweight 13 offsets the weight of the bucket 5, improving the operating efficiency of the device and reducing the energy consumption and load of the winch 14.

[0030] This utility model discloses a hopper lifting device for a mixing plant. During operation, the concrete to be lifted and transported is placed inside the hopper body 5. Due to the weight of the concrete, the hopper body 5 is pressed down, causing the hopper body 5 to be subjected to eccentric rotation and press down on the power device, thereby keeping the hopper body 5 stable. The traction device drives the support seat 3 to slide upward, so that the support seat 3 drives the hopper body 5 to be lifted and transported upward. When it is necessary to discharge the concrete, the power device lifts one side of the hopper body 5 upward, so that the hopper body 5 rotates and pours the concrete outward for discharge.
