Description

Technical Field

[0001] This invention relates to the technical field of weighing structures for underground presses, and more particularly to a lifting and single-point direct weighing structure for an underground press. Background Technology

[0002] The underground waste compactor is a waste disposal device buried deep underground. It mainly consists of an external frame and a compression plate mounted on the external frame. The compression plate is driven by a hydraulic system to compress the waste to one-third of its original volume. Only the disposal opening is located on the ground, which can isolate odors, control wastewater, reduce noise, save land and blend into the environment. Its high-efficiency compression reduces transportation costs, and it is widely used in communities, towns, and public places.

[0003] Currently, the compression plates of underground presses are controlled by a relatively complex hydraulic system. However, this complex hydraulic system has the following problems: after the underground press carries garbage, it is necessary to weigh the garbage. However, the existing weighing structure requires multiple pressure sensors to measure the pressure, which is relatively complex and cannot weigh the garbage immediately after it is loaded. To solve the above problems, a lifting and single-point direct weighing structure for underground presses needs to be proposed. Summary of the Invention

[0034] Example 1

[0035] Reference Figures 1-4 This utility model also discloses a lifting and single-point direct weighing structure for an underground press. Preferably, the main body of the underground press includes an external frame M and a container for carrying garbage, which is set on the upper end of the external frame M.

[0036] Furthermore, this weighing structure includes a weighing component 100, which in this embodiment includes a pressure measuring element 101 disposed within the outer frame M, a support element 102 slidably disposed within the outer frame M, and a contact element 103 disposed on the support element 102 corresponding to the pressure measuring element 101.

[0037] The pressure measuring element 101 is disposed on the bottom surface of the outer frame M and is located on one side of the outer frame M.

[0038] In this embodiment, the support member 102 includes a support plate slidably connected to the outer frame M, a support bracket disposed on the support plate, and a secondary support frame disposed on the support bracket. The outer side of the support plate cooperates with the outer frame M, so that when the support plate slides, the support plate is restricted by the outer frame M and only slides in the longitudinal direction. The support bracket extends upward from the upper end of the support plate and is disposed on both sides of the long side of the support plate, and includes at least one horizontal bar and two longitudinal bars.

[0039] Furthermore, in this embodiment, the pressure measuring component 101 includes a receiving column 101a disposed within the outer frame M, a pressure sensor 101b disposed on the receiving column 101a, and a weighing force transmission shaft 101c disposed on the receiving column 101a. The upper end of the weighing force transmission shaft 101c contacts the lower end of the receiving plate. The receiving column 101a is disposed within the outer frame M and is fixedly connected to the bottom surface of the outer frame M by bolts. The pressure sensor is fixedly connected to the receiving column 101a and is kept vertically arranged.

[0040] Preferably, the weighing force transmission shaft 101c is located at the upper end of the pressure sensor, and after being subjected to the pressure of the receiving plate, it will transmit the pressure to the pressure sensor.

[0041] Furthermore, the contact element 103 is disposed near the edge of the receiving plate and is correspondingly disposed with the pressure sensor. Only one set of pressure sensor and contact element 103 is disposed. In this embodiment, the contact element 103 includes an extension sleeve 103a disposed on the receiving plate and a lifting column 103b slidably connected to the extension sleeve 103a. After sliding, the lifting column 103b extends out of the lower surface of the receiving plate. In the initial state, the lower end of the lifting column 103b extends downward out of the lower surface of the receiving plate. When the receiving plate moves down, the lower end of the lifting column 103b abuts against the weighing force transmission shaft 101c. Under the obstruction of the weighing force transmission shaft 101c, the lifting column 103b will gradually slide upward. The receiving plate supports the garbage bin, and the upward sliding of the lifting column 103b will lift the garbage bin upward. At this time, the lifting force is transmitted to the pressure sensor to realize weighing.

[0042] Preferably, a slot 104 is provided on the receiving plate for connecting the extension sleeve 103a. The extension sleeve 103a is engaged in the slot 104, and retaining rings 105 are provided at both ends of the extension sleeve 103a extending out of the receiving plate. Side plates 106 are provided at both ends of the lifting column 103b and are engaged with the retaining rings 105. The side plates 106 and retaining rings 105 play a limiting role.

[0043] Furthermore, a number of columns 107 are arranged on the bottom surface of the outer frame M. The columns 107 are arranged in an array on the bottom surface of the outer frame M. In this embodiment, there are four columns 107, which are respectively arranged near the four corners of the outer frame M. The upper end of the column 107 is provided with a contact plate, thereby increasing the contact area between the column 107 and the receiving plate.

[0044] Preferably, a guide bar is provided on the outer wall of the lifting column 103b, and a groove 201b-3 that cooperates with the guide bar is provided on the inner wall of the extension sleeve 103a. When the lifting column 103b slides, the guide bar also slides in the groove 201b-3.

[0045] Preferably, this embodiment also includes a lifting assembly 200, which controls the movement of the bearing member 102 and the pressure measuring member 101 to perform downward pressure measurement. In this embodiment, the lifting assembly 200 includes several hydraulic cylinders disposed in the outer frame M. The hydraulic cylinders are connected to the support plate and will pull the support plate to move up and down.

[0046] The rest of the structure is the same as in Example 1.

[0047] Operation process: The lifting assembly 200 moves upward to receive the garbage container, and then moves in the opposite direction to lift the assembly 200, causing the receiving plate to move downward. In this state, the lifting column 103b is subjected to the pressure of the garbage container, and the lower end of the lifting column 103b extends downward beyond the lower surface of the receiving plate. After the receiving plate moves downward, the lower end of the lifting column 103b abuts against the weighing force transmission shaft 101c. As the receiving plate continues to move downward, and under the resistance of the weighing force transmission shaft 101c, the lifting column 103b will gradually slide upward, thereby lifting the garbage container. The lifting force is transmitted to the pressure sensor to achieve weighing.

[0048] This weighing structure can measure the weight of the garbage container using only a single set of pressure measuring elements 101, which saves the number of sensors compared to existing technologies, and the weighing is achieved using a single structure, making it simple and effective.

[0049] Example 2

[0050] Reference Figures 5-6 The difference between this embodiment and the previous embodiment is that it also includes a lifting assembly 200. In this embodiment, the lifting assembly 200 includes a first lifting member 201 and a second lifting member 202 movably connected to the first lifting member 201. The first lifting member 201 and the second lifting member 202 cooperate with each other, and the overall size of the first lifting member 201 and the second lifting member 202 is the same. After the second lifting member 202 rotates, it will retract into the first lifting member 201.

[0051] Furthermore, in this embodiment, the first lifting member 201 includes a first support body 201a rotatably connected to the outer frame M and a movable member 201b disposed at the end of the first support body 201a away from the outer frame M. The first support body 201a is a frame structure connected to the inner bottom surface of the outer frame M, and the size of the frame structure is larger than the size of the second lifting member 202.

[0052] Furthermore, in this embodiment, the second lifting member 202 includes a second support body 202a hinged to the first support body 201a and a hinge member 202b disposed at the end of the second support body 202a away from the outer frame M. A movable member 201b is also disposed at the end of the second support body 202a near the outer frame M.

[0053] The second support body 202a consists of an outer frame M and a rigid plate set inside the outer frame M. The rigid plate mainly serves to strengthen the overall strength of the second support body 202a. The overall dimensions of the second support body 202a are matched with the inner diameter of the frame structure of the first support body 201a.

[0054] Furthermore, the first support body 201a and the second support body 202a are hinged together, and the hinge position is set at the center of the side of the first support body 201a and the second support body 202a. Preferably, the end of the second support body 202a is also provided with an inclined surface that cooperates with the support rod. Because of the inclined surface, the second support body 202a will not be blocked by the support rod at the point where it cooperates with the support rod, so that the second support body 202a can completely enter the rectangular space enclosed by the first support body 201a when rotating.

[0055] Furthermore, a lifting support 203 is provided between the first lifting member 201 and the bearing member 102.

[0056] Furthermore, the connection between the second support body 202a and the receiving plate is hinged, while the connection between the first support body 201a and the receiving plate is made through a movable part 201b.

[0057] In this embodiment, the movable component 201b is used to connect the first support body 201a to the lower surface of the receiving plate, and to connect the second support body 202a to the bottom surface of the outer frame M. Only the movable component 201b located at the end of the first support body 201a is described here; the movable component 201b at the end of the second support body 202a is located on the inner bottom surface of the outer frame M, and the rest of the structure is the same.

[0058] In this embodiment, the movable component 201b includes a rotating body 201b-1 rotatably connected to the end of the first support body 201a away from the outer frame M, a sliding guide rail 201b-2 disposed at the lower end of the bearing component 102, and a sliding groove 201b-3 formed on the sliding guide rail 201b-2, and a sliding rod 201b-4 extending from the rotating body 201b-1 to cooperate with the sliding groove 201b-3.

[0059] Furthermore, the lifting support 203 includes a telescopic member 203a hinged to the first support body 201a and a hinged base 203b disposed at both ends of the telescopic member 203a. The telescopic member 203a is symmetrically disposed on the first support body 201a, and the end of the telescopic member 203a away from the first support body 201a is hinged to the receiving support.

[0060] Furthermore, the telescopic component 203a is an electrically controlled hydraulic cylinder, which is controlled by electricity.

[0061] Operation process: During the lifting action, the operator remotely controls the start of the electric hydraulic cylinder. The electric hydraulic cylinder extends and continuously pushes the first support body 201a and the receiving support body away from each other. Under the constraint of the hinge position and the movable part 201b, the first support body 201a and the second support body 202a will change from a state of being close to each other to a state of being far apart, thereby continuously pushing the receiving plate upward to realize the lifting action.

[0062] The lifting and single-point direct weighing structure of this underground press is simple and is controlled by an electric hydraulic cylinder. When not in operation, the lifting and single-point direct weighing structure of the underground press can be completely retracted, saving space.
