Description

Technical Field

[0001] The utility model relates to the field of concrete containers, in particular to a bottom-discharging concrete container. Background Art

[0002] Concrete is a commonly used raw material in the modern construction industry. The common usage of concrete is pouring, that is, pouring fluid concrete into a pre-made mold, and waiting for the concrete to solidify naturally. Usually, workers pour the concrete into the mold with a bucket. When adding concrete to some molds with a relatively high height that workers cannot directly pour, hoisting of the concrete is required, which is inconvenient to use.

[0003] The Chinese utility model patent with the publication number of CN214297462U discloses a bottom-discharging concrete bucket, including: a bucket body for containing concrete, with a discharge port below it, and the lower surface of the discharge port is an arc-shaped cutting surface; a support frame arranged on the outer wall of the bucket body for supporting the bucket body, so that there is a certain distance between the discharge port and the placement surface of the bucket body; a discharging mechanism is provided, and the baffle is driven by the discharging mechanism to unload the material.

[0004] For a bottom-discharging concrete bucket disclosed in the existing patent, it can realize discharging concrete from the bottom. However, from the description in its specification "There is a locking mechanism on the bucket to lock the discharging mechanism, so that the baffle keeps the discharge port sealed. The locking mechanism is a clamping part hinged to the outer wall of the bucket body to clamp the discharging mechanism to keep the discharging mechanism in a stable state. The clamping part has at least a clamping groove for clamping the discharging mechanism", it can be seen that the baffle cannot be opened before the locking mechanism is disengaged from the discharging mechanism, that is, the concrete cannot be discharged. And the locking mechanism is arranged on the bucket body. Therefore, workers need to operate at a height where they can reach the locking mechanism, which may require workers to climb, and there is a certain risk in use, so it needs to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bottom-discharging concrete container, and its advantage is that it can reduce the operating height of workers and improve safety.

[0006] To achieve the above purpose and other related purposes, the utility model provides the following technical solution: A bottom-discharging concrete container includes a housing, a discharge port is arranged at the bottom of the housing, and a baffle for blocking the discharge port is hinged on the housing. It also includes:

[0007] A support body for supporting the housing; and,

[0008] An opening and closing mechanism for driving the baffle to open and close, comprising: a first connecting rod with a middle part hinged to the support body; a second connecting rod with two ends respectively hinged to the baffle and one end of the first connecting rod, and when the connecting end of the first connecting rod and the second connecting rod rotates and lifts, the second connecting rod drives the baffle to rotate and open; and a third connecting rod with a middle part hinged to the support body and arranged in the vertical direction in the natural hanging state, when the bottom end of the third connecting rod is forced to lift, the top end of the third connecting rod applies a downward pressure for its rotation to the end of the first connecting rod far from the second connecting rod, so that the connecting end of the first connecting rod and the second connecting rod rotates and lifts.

[0009] Through the above technical solution, when in the initial state, the third connecting rod is in the hanging state and does not apply pressure to the first connecting rod, the first connecting rod and the second connecting rod are both in a static state, and the baffle blocks the discharge port; when adding concrete is needed, the operator lifts the bottom of the third connecting rod. When lifting, the third connecting rod applies a downward pressure for its rotation to the end of the first connecting rod far from the second connecting rod. While this end sinks, the end of the first connecting rod connected to the second connecting rod lifts. Under the transmission of the second connecting rod, the baffle opens and the concrete is discharged. This solution reduces the working height by setting the working position at the bottom end of the third connecting rod, so that the operator can open the baffle at a relatively low height without climbing, improving safety.

[0010] In an embodiment of the present invention, a sliding groove with a length direction the same as that of the first connecting rod is provided at the end of the first connecting rod far from the second connecting rod, and a sliding pin is provided at the top end of the third connecting rod, and the sliding pin is slidably assembled in the sliding groove.

[0011] Through the above technical solution, the sliding groove provides a margin for the relative movement of the third connecting rod and the second connecting rod during their relative rotation, so that the third connecting rod and the second connecting rod can rotate relative to each other instead of being stuck.

[0012] In an embodiment of the present invention, a handle is fixed to the bottom end of the third connecting rod.

[0013] Through the above technical solution, it is convenient for the operator to operate.

[0014] In an embodiment of the present invention, the baffles are arranged in pairs, and the two baffles are abutted and joined under the action of gravity in the natural state to block the discharge port, and two corresponding second connecting rods are hinged to the same end of the first connecting rod.

[0015] Through the above technical solution, the two baffles open synchronously when the first connecting rod rotates and lifts.

[0016] In an embodiment of the present utility model, hanging ears are fixed on the housing.

[0017] Through the above technical solution, hoisting is facilitated.

[0018] As described above, the bottom-discharging concrete container of the present utility model has the following beneficial effects:

[0019] When in the initial state, the third connecting rod is in a hanging state, the third connecting rod does not exert pressure on the first connecting rod, the first connecting rod and the second connecting rod are both in a static state, and the baffle blocks the discharge port; when concrete needs to be added, the operator lifts the bottom of the third connecting rod. When lifting, the third connecting rod exerts a pressure on the end of the first connecting rod far from the second connecting rod to cause it to rotate and sink. While this end sinks, the end of the first connecting rod connected to the second connecting rod rises. Under the driving action of the second connecting rod, the baffle opens and the concrete is discharged. In this solution, the operation position is set at the bottom end of the third connecting rod to reduce the operation height, so that the operator can open the baffle at a relatively low height without having to climb, improving safety.

[0024] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0025] Please refer to Figure 1 , the present utility model provides a bottom-discharging concrete container, including:

[0026] A housing 1 is provided with a discharge port at the bottom thereof. The discharge port is set as an arc-shaped cutting port. A baffle 2 is hinged on the housing 1. The baffles 2 are arranged in pairs. The two baffles 2 are abutted and joined under the action of gravity in the natural state to block the discharge port.

[0027] Please refer to Figure 1 , a support 3, which supports the housing 1 so that the housing 1 is arranged at a certain height from the ground.

[0028] Please refer to Figure 1 and Figure 2 , and further includes an opening and closing mechanism 4 for driving the baffle 2 to open and close. The opening and closing mechanism 4 includes:

[0029] A first connecting rod 41 with the middle part hinged to the support 3. The length direction of the first connecting rod 41 is arranged along the horizontal direction, and one end is located below the baffle 2; two second connecting rods 42, one end of each second connecting rod 42 is respectively hinged to one baffle 2, and the ends of the second connecting rods 42 far from the baffles 2 are both hinged to the end of the first connecting rod 41 located below the baffle 2. The two second connecting rods 42 are arranged at an angle. When the connecting end of the first connecting rod 41 and the second connecting rod 42 rotates and lifts, the hinged position of the second connecting piece and the first connecting rod 41 and the hinged position of the baffle 2 and the cylinder will approach each other. Therefore, the angles between the two second connecting rods 42 and the two baffles 2 will both widen, causing the baffle 2 to rotate and open; and,

[0030] A third connecting rod 43 with the middle part hinged to the support 3 and arranged vertically in the natural hanging state. A sliding groove 5 with the length direction the same as that of the first connecting rod 41 is provided at the end of the first connecting rod 41 far from the second connecting rod 42. A sliding pin 6 is fixed at the top end of the third connecting rod 43. The sliding pin 6 is slidably assembled in the sliding groove 5. A handle 7 for manual operation is fixed at the bottom end of the third connecting rod 43. When the bottom end of the third connecting rod 43 is pulled and lifted, the top end of the third connecting rod 43 applies a downward pressure for its rotation to the end of the first connecting rod 41 far from the second connecting rod 42 through the sliding pin 6, so that the connecting end of the first connecting rod 41 and the second connecting rod 42 rotates and lifts. The sliding groove 5 provides a margin for the relative movement of the third connecting rod 43 and the second connecting rod 42 during relative rotation, enabling the third connecting rod 43 and the second connecting rod 42 to rotate relative to each other.

[0031] Please refer to Figure 1 , a hanging ear 8 is fixed on the housing 1 for convenient hoisting.

[0032] When the utility model is in the initial state, the third connecting rod 43 is in a hanging state, the third connecting rod 43 does not apply pressure to the first connecting rod 41, the first connecting rod 41 and the second connecting rod 42 are both in a static state, and the baffle 2 blocks the discharge port; when adding concrete is needed, the operator lifts the bottom of the third connecting rod 43. When lifting, the third connecting rod 43 applies a pressure to the end of the first connecting rod 41 away from the second connecting rod 42 to rotate and sink it. While this end sinks, the end of the first connecting rod 41 connected to the second connecting rod 42 is lifted. Under the driving action of the second connecting rod 42, the baffle 2 is opened and the concrete is discharged. In this solution, the operation position is set at the bottom end of the third connecting rod 43 to reduce the operation height, so that the operator can open the baffle 2 at a relatively low height without having to climb, improving safety.
