Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing equipment, in particular to an opening-type concrete discharging hopper. Background Art

[0002] A concrete discharging hopper is a transition hopper for finished concrete to fall into a mixer truck after being discharged from a mixing equipment, and it is mainly used for aggregating, temporarily storing and buffering; traditional concrete discharging hoppers generally have two discharging methods. One is an open and uncovered structure. After the concrete enters the discharging hopper, it will directly be discharged from the opening of the discharging hopper into the mixer truck. The other is to add a discharging door to the discharging hopper. Currently, an arc-shaped door structure discharging door is generally adopted, and the opening and closing of the discharging hopper are realized by the rotation of the arc-shaped door panel.

[0003] However, for the first discharging method, dripping will occur after the concrete discharging is completed, causing on-site pollution and waste; for the second discharging door with an arc-shaped door structure, the opening and closing of the discharging hopper are realized by rotating the arc-shaped door. Due to the easy coagulation property of concrete, the arc-shaped door is likely to be stuck with the main body of the discharging hopper and needs to be frequently maintained. Summary of the Utility Model

[0004] The utility model discloses an opening-type concrete discharging hopper, mainly solving the problem that the arc-shaped door is likely to be stuck with the main body of the discharging hopper after the traditional discharging hopper discharges materials.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] The utility model provides an opening-type concrete discharging hopper, including a housing. A discharging cavity is arranged in the housing. A discharging inlet and a discharging outlet communicated with the discharging cavity are arranged on the housing. Oppositely arranged opening discharging doors are symmetrically arranged at a position of the housing corresponding to the discharging outlet. One end of the discharging door is rotatably connected to the housing, and the discharging door is driven by a hydraulic cylinder. Two ends of the hydraulic cylinder are respectively rotatably connected to the corresponding discharging door through swing arms.

[0007] In an embodiment, one end of the discharging door rotatably connected to the housing is inclined in a direction gradually away from the housing towards the other end.

[0008] In an embodiment, a rotating shaft is arranged at one end of the discharging door rotatably connected to the swing arm, and the rotating shaft is rotatably connected to the housing.

[0009] In an embodiment, connecting seats are respectively arranged at two ends of the hydraulic cylinder, and the connecting seats are rotatably connected to the swing arms.

[0010] In an embodiment, one end of the swing arm facing the hydraulic cylinder is bent towards the hydraulic cylinder.

[0011] In one embodiment, a limiting plate is provided on one side of the housing corresponding to the discharge door away from the discharge chamber.

[0012] In one embodiment, wear-resistant liners are provided on the surface of the discharge door facing the discharge chamber and on the inner wall of the discharge chamber.

[0013] In one embodiment, both ends of the rotating shaft are rotatably connected to the housing through bearing seats.

[0014] The advantages or beneficial effects in the above technical solutions at least include: When discharging is required, since there is a discharge chamber in the housing, a discharge inlet and a discharge outlet communicating with the discharge chamber are provided on the housing, and split discharge doors are symmetrically provided at the position of the housing corresponding to the discharge outlet. One end of the discharge door is rotatably connected to the housing, and the discharge door is driven by a hydraulic cylinder. Both ends of the hydraulic cylinder are respectively rotatably connected to the corresponding discharge door through swing arms. Therefore, by controlling the cooperation of the hydraulic cylinder and the swing arms, the two discharge doors can be driven to rotate simultaneously to control the two discharge doors to open or close simultaneously, and the concrete can be discharged from between the two discharge doors. When the discharge door is opened, it is in a large inclination state, with little resistance to the concrete, not easily worn, stable material flow, not easily splashing. In the split mode of the two discharge doors, it forms an overall open structure without aggregate dead corners, which can avoid jamming between the discharge door and the housing and reduce the maintenance frequency; at the same time, by controlling the stroke of the hydraulic cylinder, the opening amplitude of the two discharge doors can be adjusted to achieve the flow rate adjustment of discharging.

[0034] See Figure 1 and Figure 2, an embodiment of the present utility model provides a split-type concrete discharge hopper, which includes a housing 1. A discharge chamber 11 is provided in the housing 1. A discharge inlet 12 and a discharge outlet 13 that communicate with the discharge chamber 11 are provided on the housing 1. Oppositely arranged split discharge doors 2 are symmetrically provided at the position of the housing 1 corresponding to the discharge outlet 13. One end of the discharge door 2 is rotatably connected to the housing 1. The discharge door 2 is driven by a hydraulic cylinder 4. Both ends of the hydraulic cylinder 4 are respectively rotatably connected to the corresponding discharge door 2 through swing arms 3.

[0035] With the above structure, when discharging is required, since there is a discharge chamber 11 in the housing 1, a discharge inlet 12 and a discharge outlet 13 that communicate with the discharge chamber 11 are provided on the housing 1, oppositely arranged split discharge doors 2 are symmetrically provided at the position of the housing 1 corresponding to the discharge outlet 13. One end of the discharge door 2 is rotatably connected to the housing 1. The discharge door 2 is driven by a hydraulic cylinder 4. Both ends of the hydraulic cylinder 4 are respectively rotatably connected to the corresponding discharge door 2 through swing arms 3. Therefore, by controlling the cooperation of the hydraulic cylinder 4 and the swing arms 3, the two discharge doors 2 can be driven to rotate simultaneously to control the two discharge doors 2 to open or close simultaneously. The concrete can be discharged between the two discharge doors 2. When the discharge doors 2 are opened, they are in a large inclination state. The discharge doors 2 have little resistance to the concrete, are not easily worn, the material flow is stable, and it is not easy to splash. In the split mode of the two discharge doors 2, it forms an overall open structure without dead ends for aggregate collection, which can avoid jamming between the discharge doors 2 and the housing 1 and reduce the maintenance frequency; at the same time, by controlling the stroke of the hydraulic cylinder 4, the opening amplitude of the two discharge doors 2 can be adjusted to achieve the adjustment of the discharge flow rate.

[0036] In one embodiment, see Figure 1 and Figure 2 . One end of the discharge door 2 rotatably connected to the housing 1 is inclined in a direction gradually away from the housing 1 towards the other end. In actual use, the inclined setting of the discharge door 2 can reduce the impact force of the concrete on the discharge door 2 to reduce the wear of the discharge door 2.

[0037] One end of the discharge door 2 rotatably connected to the swing arm 3 is provided with a rotating shaft 21. The rotating shaft 21 is rotatably connected to the housing 1. Both ends of the rotating shaft 21 are rotatably connected to the housing 1 through bearing seats 8. In actual use, the bearing seats 8 are used to rotatably connect the rotating shaft 21 to the housing 1 so that the rotating shaft 21 can rotate smoothly on the housing 1.

[0038] In one embodiment, see Figure 1 and Figure 2Both ends of the hydraulic cylinder 4 are respectively provided with connecting seats 5, and the connecting seats 5 are rotatably connected to the swing arms 3. Among them, one end of the swing arm 3 facing the hydraulic cylinder 4 is bent towards the hydraulic cylinder 4, so that when the hydraulic cylinder 4 drives the swing arm 3 to drive the discharge door 2 to rotate, the swing angle of the swing arm 3 can be increased during the swinging process of the swing arm 3, so as to increase the opening space of the discharge door 2, which is beneficial to discharging. In practical applications, the connecting seat 5 is used to rotatably connect the swing arm 3 and the hydraulic cylinder 4, so that during the telescopic process of the hydraulic cylinder 4, it can be rotatably connected to the swing arm 3, so as to drive the swing arm 3 to swing around the rotating shaft 21, thereby being able to control the rotation of the discharge door 2.

[0039] A limiting plate 6 is provided on the housing 1 corresponding to the side of the discharge door 2 away from the discharge cavity 11. In practical applications, the setting of the limiting plate 6 can limit the amplitude when the two discharge doors 2 are opened in opposite directions, and avoid the ineffective stroke of the discharge door 2 continuing to open outwards after being opened to a vertical state.

[0040] Wear-resistant liners 7 are provided on the surface of the discharge door 2 facing the discharge cavity 11 and the inner wall of the discharge cavity 11. In practical applications, the setting of the wear-resistant liners 7 can protect the inner wall of the discharge cavity 11 and the discharge door 2, and avoid wear between the inner wall of the discharge cavity 11 and the discharge door 2.

[0041] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.
