Description

Technical Field

[0001] This utility model relates to the field of concrete hopper technology, and specifically to a concrete hopper with a gate connection mechanism. Background Technology

[0002] The casting of precast T-beams is completed by a concrete hopper. The bottom of the hopper body in the concrete hopper device is open, and a gate structure is connected to the bottom of the hopper body. The size of the bottom opening of the hopper body is controlled by the gate structure, thereby controlling the concrete discharge speed in the hopper body. Most current hopper gates are jaw gates. A jaw gate consists of two gate bodies, which are rotatably connected to the bottom of the hopper in pairs. Both gate bodies are equipped with gate teeth, which mesh with each other. When either gate body is rotated, the meshing of the gate teeth on the two gate bodies causes both gate bodies to rotate simultaneously, thereby adjusting the size of the bottom opening of the hopper and thus regulating the discharge speed of the hopper.

[0003] In the existing technology, when driving the two gate bodies to rotate, a power component such as a manual pull rod or an electric push rod is mainly used to drive one of the gate bodies to rotate. When the gate body rotates, it drives the other gate body to rotate, thereby adjusting the size of the opening at the bottom of the hopper body. Although the existing drive method can drive two gate bodies to rotate synchronously, in actual use, in order to stably and effectively drive the gate bodies to rotate, especially to push and pull the gate bodies to rotate at different angles, it is necessary to hinge the output end of the manual pull rod or electric push rod to one of the gate bodies, and then hinge the side wall of the manual pull rod or electric push rod to the frame or hopper body. This results in a complex installation structure. In addition, the manual pull rod or electric push rod will rotate or swing relative to the hopper during use. The operator can apply force manually after the angle of the manual pull rod changes, while the swinging of the electric push rod poses certain safety hazards to the space around the hopper. Furthermore, the power component can only be rotatably connected to one of the gate bodies. When driving the gate body to rotate, one gate body is subjected to the push and pull force of the power component, while the other gate body rotates relative to the other gate body under the transmission of the gate teeth. The force form and force direction of the two gate bodies are different, resulting in poor gate structure stability and affecting the pouring quality. Utility Model Content

[0004] The present invention aims to provide a concrete hopper with a gate connection mechanism to solve the problems of inconvenient driving and poor stability of the gate structure of concrete hoppers in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution: a concrete hopper with a gate connection mechanism, including a hopper body and two gate bodies rotatably connected to the hopper body and arranged opposite each other, a driving gap is provided between the two gate bodies, a driving component is slidably connected in the driving gap, gate teeth are provided on both gate bodies, and driving teeth are provided on the driving component to mesh with the two gate teeth.

[0006] The principles and beneficial effects of this application are as follows:

[0007] In this application, a drive gap is provided between the two gate bodies. The gate teeth of the two gate bodies do not directly mesh, but are slidably connected to the drive component within the drive gap. Drive teeth that mesh with the two gate teeth are provided on both sides of the drive component. When the drive component slides relative to the two gate teeth, the two gate bodies rotate in opposite directions under the driving action of the drive teeth, causing the ends of the two gate bodies to move closer or further apart. When the ends of the two gate bodies move closer together, the opening of the bottom of the hopper body decreases, thereby reducing the concrete discharge speed. When the ends of the two gate bodies move further apart, the concrete discharge speed increases.

[0008] In this application, the driving component is positioned between the two gate bodies. When the driving component slides relative to the two gate bodies, the two gate bodies are subjected to symmetrical and uniform forces during rotation because the driving component is located between the two gate bodies, effectively improving the stability of the overall hopper structure. In addition, with the technical solution in this application, the driving component only needs to slide along a straight line to drive the gate body to rotate, avoiding the inconvenience or safety hazards caused by the swinging of manual levers or electric push rods in the prior art, making it more convenient and safer to use.

[0009] Preferably, as an improvement, the drive unit is connected to a drive mechanism, and the two gate bodies are located between the drive mechanism and the hopper body.

[0010] In this scheme, the drive mechanism is used to move the drive component to achieve automatic drive. It can effectively control the sliding distance of the drive component, thereby accurately controlling the rotation angle of the gate body to accurately control the concrete discharge speed. In addition, the two gate bodies are located between the hopper body and the drive mechanism. On the one hand, the drive mechanism is located on the outside, which is convenient for installation and maintenance. On the other hand, the drive mechanism can provide a certain shielding and protection for the engagement between the gate body and the drive component, which is conducive to the more stable operation of the entire gate connection structure.

[0011] Preferably, as an improvement, the drive mechanism includes an electric push rod and a connecting rod, with the connecting rod rotatably connected between the electric push rod and the drive member.

[0012] In this solution, the drive mechanism includes an electric push rod and a connecting rod. One end of the connecting rod is rotatably connected to the output shaft of the electric push rod, and the other end of the connecting rod is rotatably connected to the drive component. In actual fixing, it is only necessary to set the output shaft of the electric push rod parallel to the sliding direction of the drive component. The extension and retraction of the output shaft of the electric push rod can push the drive component to move through the connecting rod, so as to accurately and stably control the concrete feeding speed.

[0013] Preferably, as an improvement, the driving element includes a rack, with driving teeth disposed on both sides of the rack.

[0014] In this solution, the driving component is a rack, with driving teeth on both sides. The driving teeth on both sides mesh with the gate teeth of the two gate bodies respectively. The structure is simple, easy to process and install, and the meshing is stable, which can stably realize meshing transmission.

[0015] Preferably, as an improvement, it also includes a frame, wherein the hopper body, the drive component and the drive mechanism are all connected to the frame, and a slide rail is fixedly connected to the frame, and the drive component slides in cooperation with the slide rail.

[0016] In this design, a frame is installed, and the hopper body, drive components, and drive mechanism are all connected to the frame. At the same time, a slide rail is fixed on the frame, and the drive components slide in cooperation with the slide rail. The slide rail provides limit and guidance for the sliding of the drive components, making the sliding of the drive components smoother and more precise, and the concrete feeding speed adjustment more stable and accurate.

[0017] Preferably, as an improvement, a limiting component is fixedly connected to the drive component, and a clamping component that cooperates with the limiting component is fixedly connected to the frame. When the two gate bodies rotate to contact each other, the limiting component and the clamping component come into contact.

[0018] In this design, a limiting component is installed on the drive unit, and a clamping component that cooperates with the limiting component is fixed on the frame. When the two gate bodies rotate to the point where their ends contact each other and completely close the opening at the bottom of the hopper body, the concrete feeding is stopped. At the same time, the limiting component moves to contact the clamping component. The interaction between the limiting component and the clamping component prevents the drive unit from continuing to slide and prevents the two gate bodies from continuing to rotate in the direction of mutual approach. This prevents the two gate bodies from being squeezed too much and deformed, thus providing good protection for the gate bodies.

[0019] Preferably, as an improvement, the limiting member includes a limiting seat fixedly connected to the driving member, and the abutting member includes an abutting seat fixedly connected to the frame.

[0020] Preferably, as an improvement, the limiting seat is fixedly connected to the end face of the drive member away from the frame, and one end of the limiting seat extends to the side of the drive member where the drive teeth are provided, and the abutment seat contacts the portion of the limiting seat that extends to the side of the drive member.

[0021] In this scheme, the sliding of the drive component is limited by the mutually cooperating limit seat and the abutment seat. The limit seat is fixed to the end face of the drive component away from the frame. One end of the limit seat extends to the side of the drive component where the drive teeth are set. When the drive component slides relative to the gate body, the drive component can drive the limit seat to slide synchronously. No matter what state the drive component and the gate body slide to, the limit seat will not affect the meshing process of the drive teeth and the gate teeth.

[0022] Preferably, as an improvement, the number of limiting seats is two, and the ends of the two limiting seats extend beyond the driving teeth on both sides of the driving member, and the number of abutting seats is equal to the number of limiting seats and is set in a one-to-one correspondence.

[0023] In this solution, by setting two limiting seats and two abutting seats, when the driving component drives the limiting seats to slide to contact and abut with each other, the driving component is evenly stressed on both sides, avoiding uneven stress caused by one side of the driving component and improving the uniformity of the force on the driving component.

[0024] Preferably, as an improvement, a cushioning pad is fixedly connected to the abutment seat.

[0025] In this scheme, a buffer pad is fixed on the clamping seat. The buffer pad plays a buffering and protective role during the contact and clamping process between the limiting seat and the clamping seat. It also plays a buffering role during the process of the two gate bodies rotating to clamp each other, thus achieving buffering and protection of the gate bodies. Attached Figure Description

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: frame 1, hopper body 2, gate body 3, gate tooth 301, slide rail 4, rack 5, drive tooth 501, electric push rod 6, connecting rod 7, limit seat 8, clamping seat 9, mounting groove 901, and buffer pad 10. Example

[0032] This embodiment is as shown in the attached figure. Figure 1 and Figure 2 As shown: A concrete hopper with a gate connection mechanism includes a frame 1 and a hopper body 2 fixedly connected to the frame 1 by welding. The hopper body 2 has openings at the top and bottom. The top opening is used for transferring concrete into the hopper body 2, and the bottom opening is used for pouring concrete from the hopper body 2 into the mold of a precast T-beam. Two paired gate bodies 3 are rotatably connected to the frame 1 via bearings. Each gate body 3 has gate teeth 301, and a driving gap exists between the two gate bodies 3. A driving component is vertically slidably connected within the driving gap. The driving component has driving teeth 501 that mesh with the gate teeth 301 on the two gate bodies 3. When the driving component slides vertically, the meshing transmission relationship between the driving teeth 501 and the gate teeth 301 effectively drives the two gate bodies 3 to rotate relative to the frame 1. The rotation of the two gate bodies 3 changes the opening size of the bottom opening of the hopper body 2, thereby adjusting the speed at which the hopper body 2 pours concrete into the precast T-beam mold.

[0033] Combination Figure 1 , Figure 2 and Figure 3 In this embodiment, a vertically arranged slide rail 4 is fixedly connected to the frame 1 by screws. The driving component is a rack 5 vertically slidably connected to the slide rail 4. The rack 5 has the aforementioned driving teeth 501 on both the left and right sides, and the driving teeth 501 on both sides mesh with the gate teeth 301 of the two gate bodies 3 respectively. In order to accurately and automatically control the vertical sliding dimension of the rack 5, thereby accurately controlling the feeding speed of the hopper body 2, a driving mechanism for the vertical sliding of the driving teeth 501 relative to the slide rail 4 is connected to the frame 1 in this embodiment. The driving mechanism includes an electric push rod 6 and a connecting rod 7. The electric push rod 6 is fixedly connected to the frame 1 by screws. One end of the connecting rod 7 is hinged to the rack 5 by a pin, and the other end is hinged to the output shaft of the electric push rod 6 by a pin. When the output shaft of the electric push rod 6 extends or retracts, the rack 5 can be pushed and pulled vertically by the connecting rod 7, thereby pushing the gate body 3 to rotate and controlling the feeding speed of the hopper body 2.

[0034] Combination Figure 2 and Figure 3In this embodiment, a limiting member is fixedly connected to the rack 5, and a clamping member that cooperates with the limiting member is fixedly connected to the frame 1. When the ends of the two gate bodies 3 rotate to fit together and close the opening of the hopper body 2, the limiting member and the clamping member come into contact with each other. Specifically, the limiting member includes an upper limit seat 8 fixedly connected to the rack 5 away from the end face of the frame 1 by screws. There are two limiting seats 8, and one end of each of the two limiting seats 8 extends beyond the drive teeth 501 provided on the rack 5. The clamping member includes a clamping seat 9 fixedly connected to the frame 1 by screws. There are two clamping seats 9, and the two clamping seats 9 cooperate with the two limiting seats 8.

[0035] The specific implementation process is as follows:

[0036] When it is necessary to adjust the speed at which the hopper body 2 pours concrete into the precast T-beam mold, simply control the extension or retraction of the output shaft of the electric push rod 6. The output shaft of the electric push rod 6 can then use the connecting rod 7 to push and pull the rack 5 vertically. The drive teeth 501 on the rack 5 mesh with the gate teeth 301 to transmit power, causing the two gate bodies 3 to rotate in opposite directions. When the two gate bodies 3 rotate, they change the opening of the bottom opening of the hopper body 2, thereby precisely adjusting the concrete pouring speed.

[0037] In addition, in this embodiment, since a limiting seat 8 and abutting seat 9 are provided to cooperate with each other, when the two gate bodies 3 rotate to close to each other and close the opening at the bottom of the hopper body 2, the limiting seat 8 and abutting seat 9 abut against each other, so as to prevent the electric push rod 6 from continuing to apply pressure to the gate body 3 and causing the gate body 3 to be deformed and damaged due to excessive force, thus protecting the gate body 3. Example

[0038] The difference between Example 2 and Example 1 is as follows: Figure 4 As shown, in this embodiment, a buffer pad 10 is fixedly connected to the abutment seat 9 by adhesive bonding. The buffer pad 10 provides buffer protection against the contact between the limit seat 8 and the abutment seat 9. In addition, to avoid the buffer pad 10 affecting the precise closure of the two gate bodies 3, an installation groove 901 is provided on the side of the abutment seat 9 facing the limit seat 8. The width of the installation groove 901 is greater than the width of the buffer pad 10, and the thickness of the buffer pad 10 is greater than the depth of the installation groove 901, so that one end of the buffer pad 10 extends beyond the side of the abutment seat 9. When the limit seat 8 approaches the abutment seat 9, it first contacts the part of the buffer pad 10 that protrudes beyond the installation groove 901, and the buffer pad 10 provides buffer protection. As the limit seat 8 continues to approach the abutment seat 9, the buffer pad 10 is squeezed into the installation groove 901. When the limit seat 8 and the abutment seat 9 are pressed together, the two gate bodies 3 are in a state of mutual contact and the feeding stops. This can effectively ensure the buffer protection effect and the accuracy of control.
