Description

Technical Field

[0001] This utility model relates to the technical field of mortar mixing equipment, specifically to a mortar mixer unloading mechanism. Background Technology

[0002] In the construction industry, mortar mixers are indispensable equipment used to mix building materials such as cement, sand, and water into uniform mortar. Traditional mortar mixers use fixed discharge ports. When there is a large amount of mortar in the mixer and the mortar is in a highly mixed state, the mortar has very strong fluidity and impact force. If the discharge port is opened manually at this time, the mortar can easily gush out rapidly under the action of gravity, forming a strong spray effect, which may cause injury to the operator. Moreover, since the opening of the fixed discharge port is not adjustable, the discharge speed of the mortar cannot be adjusted according to actual needs. When slow discharge is required to avoid mortar splashing, the flow rate of the mortar cannot be effectively adjusted by adjusting the opening of the discharge port.

[0003] In view of this, we propose a discharge mechanism for a mortar mixer to solve the existing problems. Utility Model Content

[0004] The purpose of this utility model is to provide a discharge mechanism for a mortar mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a discharge mechanism for a mortar mixer, comprising:

[0006] The hopper is fixedly installed on the bracket, and the bottom of the hopper is provided with a discharge port for unloading mortar. One end of the bottom of the discharge port is provided with a movable and openable baffle.

[0007] The pusher includes a first connector and a second connector connected at one end. The pusher is movably hinged to the bracket through the connection point between the first connector and the second connector. An operating lever is connected to the other end of the first connector, and a connecting rod is connected to the other end of the second connector. The other end of the connecting rod is connected to a baffle.

[0008] The drive mechanism is connected to the operating lever.

[0009] Preferably, the pushing member is an L-shaped component, and the included angle between the first connecting member and the second connecting member is 90°.

[0010] Preferably, the baffle includes a base plate that matches and abuts against the discharge port, and the two ends of the base plate in the non-moving direction are provided with connecting plates. The other ends of the two connecting plates are hinged to a first hinge seat, and the first hinge seat is fixedly connected to the outer wall of the hopper.

[0011] Preferably, the pusher and the connecting rod are in two sets and are symmetrically installed on opposite sides of the bracket, and the ends of the connecting rods on both sides away from the pusher are respectively connected to the connecting plates on both sides of the baffle.

[0012] Preferably, the operating lever includes a free end and fixed ends integrally connected to both sides of the free end and extending perpendicularly to the free end, and the other ends of the two fixed ends are respectively fixedly connected to the first connecting members of the push members on both sides of the bracket.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a mortar mixer unloading mechanism, comprising:

[0023] Hopper 1 is fixedly installed on bracket 2. The bottom of hopper 1 is provided with discharge port 11 for unloading mortar. One end of the bottom of discharge port 11 is provided with a movable baffle 5.

[0024] The pusher 3 includes a first connector 31 and a second connector 32 connected at one end. The pusher 3 is movably hinged to the bracket 2 through the connection end point between the first connector 31 and the second connector 32. The other end of the first connector 31 is connected to an operating rod 6, and the other end of the second connector 32 is connected to a connecting rod 4. The other end of the connecting rod 4 is connected to a baffle 5.

[0025] The drive mechanism 7 is driven and connected to the operating lever 6.

[0026] Furthermore, the pusher 3 is an L-shaped component, and the included angle between the first connector 31 and the second connector 32 is 90°.

[0027] Furthermore, the baffle 5 includes a bottom plate 51 that matches and abuts against the discharge port 11. The bottom plate 51 has connecting plates 52 on both sides in the non-moving direction. The other ends of the connecting plates 52 are hinged to a first hinge seat 53, and the first hinge seat 53 is fixedly connected to the outer wall of the hopper 1.

[0028] Furthermore, the pusher 3 and the connecting rod 4 are in two sets and are symmetrically installed on opposite sides of the bracket 2. The ends of the connecting rods 4 away from the pusher 3 are respectively connected to the connecting plates 52 on both sides of the baffle 5.

[0029] Furthermore, the operating lever 6 includes a free end 61 and fixed ends 62 integrally connected to both sides of the free end 61 and extending perpendicularly to the free end 61. The other ends of the two fixed ends 62 are respectively fixedly connected to the first connecting members 31 of the upper pushing members 3 on both sides of the bracket 2.

[0030] Furthermore, the drive mechanism 7 includes a second hinge seat 73 fixedly installed at the bottom of the bracket 2. A cylinder 72 is movably hinged to the other end of the second hinge seat 73. The output shaft of the cylinder 72 is connected to one end of the drive rod 71, and the other end of the drive rod 71 is movably hinged to the free end 61 of the operating rod 6.

[0031] Furthermore, the bottom cross-sectional shape of the discharge port 11 is set in an outwardly convex arc shape, and the cross-sectional shape of the base plate 51 is set to match the bottom cross-sectional shape of the discharge port 11, so that the base plate 51 can move along the tangent direction of the arc to open or close the discharge port 11.

[0032] Furthermore, a sealing assembly is provided on the top surface of the base plate 51 to ensure that the discharge port 11 is tightly sealed when the base plate 51 is closed.

[0033] The working principle of the unloading mechanism of a mortar mixer based on Embodiment 1 is as follows: When the mortar mixer is mixing, the baffle 5 of the unloading mechanism is in a closed state, that is, the bottom plate 51 is tightly fitted with the discharge port 11 of the hopper 1 to prevent mortar leakage; when unloading is required after mixing, the drive mechanism 7 starts to work. When the cylinder 72 is started, the output shaft of the cylinder 72 extends and pushes the drive rod 71, which in turn pushes the operating rod 6 upward, causing the operating rod 6 to drive the pusher 3 to move. The pusher 3 is an L-shaped component composed of a first connecting member 31 and a second connecting member 32. When the operating rod 6 is driven, the first connecting member 31 and the second connecting member 32 rotate around the movable hinge point between the pusher 3 and the bracket 2. Since the other end of the second connecting member 32 is connected to the connecting rod 4, and the connecting rod 4 is connected to the connecting plate 52 of the baffle 5, the movement of the connecting rod 4 will drive the baffle 5 to move. With the movement of the pushing member 3, the connecting rod 4 pushes the connecting plate 52 of the baffle 5, causing the bottom plate 51 to rotate around the first hinge seat 53 along the tangent direction of the arc, thereby opening the discharge port 11. The opening degree of the baffle 5 can be adjusted by controlling the height of the lifting of the operating table by the cylinder 72. After the unloading is completed, the drive mechanism 7 works in reverse, the output shaft of the cylinder 72 retracts and pulls the drive rod 71, causing the operating rod 6 to drive the pushing member 3 to move in reverse, and the connecting rod 4 pulls the connecting plate 52 of the baffle 5, causing the bottom plate 51 to return to its original position along the same tangent direction, closing the discharge port 11.

[0034] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
