DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0031] like Figure 1 As shown in FIG. 4 , the specific scheme of the embodiment is as follows: it comprises a material placing machine 1, a conveying pipe 2 is provided on the material placing machine 1, a conveying hose 3 is provided on the conveying pipe 2, and a uniform conveying component 4 is provided between the conveying pipe 2 and the conveying hose 3;
[0032] The uniform conveying component 4 includes a connecting pipe 41 having one end connected to the conveying pipe 2. The end of the connecting pipe 41 close to the conveying pipe 2 is trumpet-shaped, and the diameter of the connecting pipe 41 at the end away from the conveying pipe 2 is larger than the diameter of the conveying pipe 2. The increase in the diameter of the connecting pipe 41 slows down the flow rate of the fluid and also reduces the pressure of the fluid. Where the pipeline is enlarged, the trumpet-shaped connecting pipe 41 adopts a gradual expansion design instead of a sudden expansion. The gradual expansion design can enable the fluid to maintain a relatively stable speed during the transition process, reduce the formation of eddies and turbulence, and thus reduce the risk of blockage.
[0033] The lower end of the connecting pipe 41 is connected to a discharge pipe 42 whose end is connected to the delivery hose 3. The discharge pipe 42 and the delivery hose 3 are fixedly connected by a clamp 421. The connecting pipe 41 and the delivery pipe 2 are also fixedly connected by a clamp 421. The setting of the clamp 421 allows the connecting pipe 41 and the delivery hose 3 to be easily disassembled and maintained.
[0034] An end cover 43 is installed at one end of the connecting pipe 41 away from the conveying pipe 2. The end cover 43 is fixedly connected to the connecting pipe 41 by fastening bolts. A buffer 44 is installed at one end of the end cover 43 located inside the connecting pipe 41. The buffer 44 includes a sleeve 441 fixedly installed on the outside of the end cover 43. The sleeve 441 is located in the middle of the end cover 43. A buffer spring 442 is fixedly connected to the inner wall of the sleeve 441. A connecting rod 443 is installed at the other end of the buffer spring 442. The connecting rod 443 It is fixedly connected to the buffer spring 442 through a connecting seat 4431, the diameter of the connecting seat 4431 is adapted to the diameter of the inner wall of the sleeve 441, and the end of the connecting rod 443 away from the buffer spring 442 is fixedly connected to a buffer plate 444, the buffer plate 444 is disc-shaped, and the outer side of the buffer plate 444 is fixedly connected to a sealing gasket 4441, the outer side of the sealing gasket 4441 is in contact with the inner wall of the connecting tube 41, and the setting of the sealing gasket 4441 can prevent the fluid from entering the inner side of the sleeve 441.
[0035] A pressure relief pipe 45 is connected between the connecting pipe 41 and the discharge pipe 42. The pressure relief pipe 45 is connected in an inclined shape, and the angle of inclination is 45 degrees. A check valve 451 is provided at one end of the pressure relief pipe 45 close to the connecting pipe 41. The check valve 451 is a disc check valve. The setting of the check valve 451 can prevent the backflow of the fluid. When the pressure of the fluid is at a normal value, the buffer plate 444 is located between the pressure relief pipe 45 and the discharge pipe 42. When the pressure of the fluid is too large, the buffer plate 444 squeezes the buffer spring 442, so that the buffer plate 444 moves to the rear end of the pressure relief pipe 45. At this time, the pressure relief pipe 45 can perform pressure relief on the fluid.
[0036] The upper end of the connecting pipe 41 is connected to a mounting seat 46, which is at the same vertical level as the discharge pipe 42. The upper surface of the mounting seat 46 is rectangular, and a through hole is provided on the surface of the mounting seat 46. The surface of the mounting seat 46 is fixedly connected to a box body 47, and a cover plate is installed on the upper end of the box body 47.
[0037] A driving member 48 is provided on the inner side of the box body 47. The driving member 48 includes a driving motor 481 fixedly mounted on the inner top wall of the box body 47. The driving motor 481 is fixedly connected to the cover plate. A driving gear 482 is fixedly connected to the output end of the driving motor 481. A driven gear 483 is movably connected to the bottom wall of the inner side of the box body 47. The driven gear 483 is meshed with the driving gear 482. A rotation groove 4831 is provided on the lower end of the driven gear 483 and the bottom wall of the inner side of the box body 47. A ball 4832 is movably connected to the inner side of the rotation groove 4831. The rotation groove 4831 cooperates with the ball 4832, so that the driven gear 483 can rotate stably.
[0038] A transmission rod 484 is installed at the lower end of the driven gear 483, and the transmission rod 484 is located on the inner side of the perforation. The top wall on the inner side of the box body 47 is movably connected to the rotating shaft 485. The rotating shaft 485 is fixedly connected to an abutment seat 486 at one end close to the driven gear 483. The abutment seat 486 is fixedly connected to a positioning column. There are four positioning columns. A positioning groove that docks with the positioning column is provided on the surface of the driven gear 483. The cooperation between the rotating shaft 485 and the abutment seat 486 can limit the driven gear 483. The driving member 48 is provided with a spiral blade 49 located on the inner side of the discharge pipe 42. The spiral blade 49 is fixedly connected to the driven gear 483 by a fixing bolt 4841.
[0039] The working principle of the above embodiment is:
[0040] When the fluid enters the connecting pipe 41 through the delivery pipe 2, the flow rate of the fluid slows down and the pressure is reduced due to the gradual expansion design of the connecting pipe 41. The drive motor 481 is started, and the drive motor 481 drives the active gear 482 to rotate. With the assistance of the rotating shaft 485 and the abutment seat 486, the meshing driven gear 483 drives the transmission rod 484 to rotate, and synchronously drives the spiral blade 49, so that the spiral blade 49 drives the fluid to rotate and stir. When the pressure of the fluid is too high, the fluid pushes the buffer plate 444, and the buffer plate 444 squeezes the buffer spring 442 through the connecting rod 443. When the buffer plate 444 moves to the rear end of the pressure relief pipe 45, the pressure relief pipe 45 can relieve the pressure of the fluid in its delivery pipe 2 to avoid excessive fluid pressure and damage to its spiral blade 49.
[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
