Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a novel movable frame structure of a screw conveyor. Background Art

[0002] In the grain processing industry, screw conveyors are used to facilitate the turnover of corn, soybeans, rice and other grains. In order to avoid the difficulty of adjustment and maintenance caused by the fixed position of the equipment, mobile racks for screw conveyors have been introduced on the market to avoid such problems. The mobile racks can be flexibly connected with grain screening equipment, packaging equipment, etc. to achieve continuous transportation and processing of materials, improve the degree of automation and production efficiency of the entire production system, and also improve the efficiency and quality of maintenance work.

[0003] In the related art, the movable frame of the screw conveyor mostly supports the screw conveyor through the U-shaped mounting groove on the top of the support base, and then drives the support plate and the screw conveyor to move through the universal wheels at the four corners of the bottom of the support plate.

[0004] However, the existing U-shaped screw conveyor has a certain weight, and the mobile frame may be equipped with other components such as motors, so the overall center of gravity is relatively high. During the movement, if the ground is uneven or the side is subjected to external force, it is easy to cause the mobile frame to tilt or even fall over, posing a safety hazard. In order to solve the above problems, a new type of screw conveyor mobile frame structure is proposed to solve the above problems. Utility Model Content

[0005] In view of this, the utility model provides a new type of screw conveyor moving frame structure, which supports the screw conveyor horizontally through vertical support plates, reinforces the horizontal force of the screw conveyor through reinforcing plates, and reinforces the longitudinal force of the screw conveyor through the connection between reinforcing rods and vertical support plates. The auxiliary support plates on the auxiliary support members prevent the vertical support plates from being offset by lateral external forces, thereby making the moving frame less likely to tip over, thereby reducing safety hazards.

[0006] In order to solve the above technical problems, the utility model provides a new type of screw conveyor mobile frame structure, including universal wheels arranged at the four corners of the bottom of the support base, vertical support plates symmetrically arranged on the top of the support base, and mounting grooves arranged between the tops of the vertical support plates. A reinforcing plate is arranged on the side surfaces of the front and rear ends of each vertical support plate, and the bottom of the reinforcing plate is connected to the upper surface of the support base. A positioning plate is welded to the front and rear ends of the support base respectively, and a jack is arranged in the middle of the positioning plate. A pad is provided at the telescopic end of each jack, and a number of auxiliary support members are symmetrically arranged on the left and right sides of the support base.

[0007] A cavity for installing the bracket is provided in the middle of the vertical support plate. Several brackets for reducing the weight of the vertical support plate are provided in the cavity. The brackets can stably support the installation slot. The brackets are X-shaped, and a first connecting rod is provided between the brackets. The first connecting rod is used to connect the brackets on both sides into one, thereby improving the supporting capacity of the vertical support plate for the installation slot.

[0008] A through-hole is provided in the middle of the positioning plate, which facilitates the telescopic end to move toward the ground when the jack is inverted. The perforation facilitates the movement of the telescopic end of the jack. A mounting base for fixing the jack is provided on the top of the jack, and the rocker on the jack faces the side away from the bottom of the support base.

[0009] A reinforcing rod is provided on the left and right sides of each positioning plate. The reinforcing rod is used to strengthen the longitudinal supporting capacity of the vertical support plate, thereby alleviating the downward pressure of the screw conveyor on the vertical support plate. The top of the reinforcing rod is connected to the vertical support plate.

[0010] The cam is adapted to move the bolts along the underside of the support member so that the bolts can be moved up and down in a controlled manner so that the bolts can be adjusted in a controlled manner so that the bolts can be moved back and forth between the support member and the underside of the support member.

[0011] A second connecting rod is provided between the reinforcing rods, and the second connecting rod is used to connect the reinforcing rods so that the reinforcing rods form a whole, thereby improving their supporting performance.

[0012] The height of the reinforcing plate is two-fifths of the height of the vertical support plate. A pushing handle is provided above the reinforcing plate. The pushing handle facilitates personnel to push the vertical support plate for pushing operations. The two ends of the pushing handle are respectively connected to the vertical support plates.

[0013] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0014] 1. The lateral force of the screw conveyor is supported by the vertical support plate body, and the lateral force of the screw conveyor is reinforced and supported by the reinforcing plates on the left and right sides of the vertical support plate. The longitudinal force of the screw conveyor can be reinforced and supported by the connection between the reinforcing rod on the positioning plate and the vertical support plate. The left and right sides of the support base are protected by auxiliary support members, and the auxiliary support plates on the auxiliary support members are used to prevent the vertical support plate from being offset by the lateral external force, so that the mobile frame is not easy to tip over, thereby reducing safety hazards.

[0015] 2. When the screw conveyor is working to position the mobile frame, the rocker on the jack is used to push the pad on the jack against the ground, thereby raising the support base and supporting the screw conveyor laterally through the pad. The adjusting nut on the auxiliary support is used to adjust the lifting and lowering of the threaded rod, so that the auxiliary support plate is fixed to the ground, thereby making the universal wheel off the ground to support the screw conveyor.

[0016] 3. In order to reduce the weight of the vertical support plate, the cavity is set up. The bracket is used to supplement the hollow position in the cavity to provide vertical support for the vertical support plate, thereby making the vertical support plate light in weight and having strong supporting capacity.

It is set obliquely, and the upper end of the reinforcing plate 200 is welded and fixed to the vertical support plate 102, and the bottom of the reinforcing plate 200 is welded to the upper surface of the support base 100. A positioning plate 201 is welded to the front and rear ends of the support base 100 respectively, and a jack 202 is set in the middle of the positioning plate 201. The jack 202 needs to be fixed upside down, and the telescopic end of the jack 202 faces the ground. A pad 203 is set at the telescopic end of each jack 202.

The through-hole 204 facilitates the telescopic end of the jack 202 to move. A mounting base 205 for fixing the jack 202 is provided on the top of the jack 202. The bottom of the mounting base 205 is connected to the bottom of the jack 202 after inversion with bolts. The pillars at the four corners of the lower surface of the mounting base 205 are connected to the upper surface of the positioning plate 201. The rocker on the jack 202 faces On the side away from the bottom of the support base 100, a reinforcing rod 206 is provided on the left and right sides of each positioning plate 201. The reinforcing rod 206 is an inclined quadrilateral. The lower end of the reinforcing rod 206 is welded and fixed to the upper surface of the positioning plate 201, and the upper end of the reinforcing rod 206 is welded and fixed to the front end or rear end of the vertical support plate 102.
