[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-5 The utility model is used for bulk metering control device of cement sand material, including rotor scale 1, frame 2, external pipe 3, material pipe 4, cloth cover 5, rotor scale 1, external pipe 3 are fixedly installed on frame 2, there are two external pipes 3, one external pipe 3 is installed at the outlet of cement storage equipment, and the other external pipe 3 is installed at the inlet of cement transfer equipment, rotor scale 1 is provided with material pipe 4, there are also two material pipes 4, one is installed at the inlet of rotor scale 1, and the other is installed at the outlet of rotor scale 1.

[0027] The external tube 3 and the material pipe 4 are connected by a cloth sleeve 5. The cloth sleeve 5 is a cylindrical structure. The upper and lower ends of the cloth sleeve 5 are respectively hung with the external tube 3 and the material pipe 4 through a hanging structure 7. During installation, the cloth sleeve 5 is first pre-hung between the external tube 3 and the material pipe 4 through the hanging structure 7, and then fixedly connected with the external tube 3 and the material pipe 4 through the clamping structure 6, thereby avoiding the need for other staff to assist in the installation, simplifying the installation steps, and improving the convenience of installation.

[0028] The hanging structure 7 includes a pull ring 701 and a hook 702. The two ends of the cloth cover 5 are fixedly connected with the pull rings 701 respectively. The outer walls of the external tube 3 and the material tube 4 are fixed with hooks 702 corresponding to the pull rings 701. The cloth cover 5 is hung on the hook 702 through the pull ring 701. When in use, the pull ring 701 at one end is first hung on the hook 702 located above, and then the pull ring 701 at the other end is hung on the hook 702 located below. In this process, the operation can be completed by one person.

[0029] The pull ring 701 is an elastic structure, which may be an elastic rubber ring, annular spring or other structures. When the pull ring 701 needs to be hung on the hook 702, a little force is applied to pull the pull ring 701 to produce elastic deformation, and then the pull ring 701 is hung on the hook 702. The elastic deformation of the pull ring 701 can be used to tighten the cloth cover 5 between the external tube 3 and the material tube 4, so that the clamping structure 6 can be used to clamp the cloth cover 5 directly in the future without the need to adjust the shape of the cloth cover 5 separately.

[0030] The upper and lower ends of the cloth cover 5 are respectively provided with U-shaped openings 501, and the U-shaped openings 501 are U-shaped notch structures. The U-shaped opening 501 at the upper end opens upward and is above the semicircular clamping ring 601 at the upper end.

[0031] The U-shaped opening 501 at the lower end opens downward, and below the semicircular clamping ring 601 at the lower end, the inner diameter of the cloth sleeve 5 is consistent with the outer diameters of the external tube 3 and the material tube 4. The U-shaped opening 501 makes it easy for the cloth sleeve 5 to be mounted on the external tube 3 and the material tube 4.

[0032] The clamping structure 6 includes a semicircular clamping ring 601 and a fixed rod 603. There are two fixed rods 603, which are respectively located on one side of the external tube 3 and the material tube 4. The end of the fixed rod 603 away from the cloth cover 5 is fixed on the frame 2 or the external tube 3 and the material tube 4. The end of the fixed rod 603 close to the cloth cover 5 is installed with a semicircular clamping ring 601. The two semicircular clamping rings 601 are rotatably installed on the fixed rod 603 through a hinge seat 602. Every time the semicircular clamping ring 601 is rotated, the cloth cover 5 is opened or closed to clamp the cloth cover 5. The two ends of the cloth cover 5 are located on the inner sides of the two fixed rods 603.

[0033] The two semicircular clamping rings 601 are respectively fixed with connecting blocks 604 , and the connecting blocks 604 are connected by bolts. After the two semicircular clamping rings 601 are closed, they are fixed together by bolts.

[0034] A semicircular rubber ring 605 is installed on the inner side of the semicircular clamping ring 601. The inner diameter of the semicircular rubber ring 605 is smaller than the inner diameter of the semicircular clamping ring 601, and larger than the outer diameters of the external tube 3 and the material tube 4. When the two semicircular clamping rings 601 are closed, the semicircular rubber ring 605 is squeezed and deformed, and the inner wall of the semicircular rubber ring 605 presses the cloth sleeve 5, fixes the cloth sleeve 5 and maintains a sealed state.

[0035] Working principle: When in use, first hang the pull ring 701 on the hook 702, so as to preliminarily fix the cloth cover 5 between the external tube 3 and the material tube 4, and then rotate the two semicircular clamping rings 601 to close and fix them with bolts. The semicircular clamping ring 601 seals and fixes the cloth cover 5 on the external tube 3 and the material tube 4 through the semicircular rubber ring 605. The cement sand storage equipment sends the cement sand into the rotor scale 1 through one set of external tubes 3, cloth cover 5 and material tubes 4. After weighing, it is sent to the cement sand transportation equipment through another set of external tubes 3, cloth cover 5 and material tubes 4, so as to control the conveying amount of cement sand.
