Description

Technical Field

[0001] The utility model relates to the technical field of machine-made sand production, in particular to a scattering machine for machine-made sand production. Background Art

[0002] Nowadays, river sand resources have become increasingly scarce. In order to solve the aggregate problem of concrete production, large-scale machine-made sand produced in quarries is used to replace river sand. Since the powder content of the machine-made sand reaches 10%-15%, and the mined raw stone used to make machine-made sand itself contains mountain soil, the machine-made sand contains more mud. When the machine-made sand with heavy mud powder enters the silo and accumulates for a certain period of time, the evaporation of water in the machine-made sand and the subsidence caused by its own weight can easily cause the machine-made sand to clump. Therefore, a disperser is needed to break up the agglomerated machine-made sand.

[0003] According to Chinese patent publication number CN215140465U, a machine-made sand breaking device includes a base plate, support rods are installed on both sides of the top surface of the base plate, the top ends of the two support rods are connected by a cylinder, a stirring motor is installed on one side of the cylinder, the stirring motor shaft passes through the cylinder and is located in the cylinder, a rotating shaft is installed at one end of the stirring motor shaft, and one end of the rotating shaft is rotatably connected to the cylinder through a bearing.

[0004] This patent number pours machine-made sand into a cylinder, and uses a motor to drive multiple L-shaped rods to rotate and break up the machine-made sand inside. The machine-made sand is directly discharged from the discharge port after breaking up. Since there are large gaps between the multiple L-shaped rods, some agglomerated machine-made sand may not be broken up, and the breaking effect is poor. Therefore, a break-up machine for machine-made sand production is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a disperser for machine-made sand production, which has the advantages of better disperser effect and the like, and solves the problem of poor disperser effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a scattering machine for machine-made sand production, comprising a base plate, a support frame is fixedly installed on the top of the base plate, a scattering box is installed on the support frame, a scattering mechanism is installed inside the scattering box, a support plate is provided on the support frame, a screening box is detachably installed on the top of the support plate, and a screening assembly is installed inside the screening box.

[0007] The scattering mechanism comprises a driving motor, which is mounted on the side wall of the scattering box. A scattering roller is fixedly connected to the output shaft of the driving motor, and the scattering roller is rotatably connected to the inside of the scattering box.

[0008] The screening assembly includes a screening frame and a U-shaped plate, a screen is embedded and fixed at the bottom of the screening frame, T-shaped clips are fixedly connected to the left and right sides of the top of the U-shaped plate, and slots are opened on the left and right sides of the bottom of the front surface of the screening frame, and the T-shaped clips are clamped in the inside of the slots. Slide blocks are fixed on the left and right sides of the U-shaped plate, and the inside of the slider is slidably connected to a slide rod, which is fixedly installed in a mounting groove opened on the inner wall of the screening box, and the outside of the slide rod is provided with springs located at the bottom and top of the slider.

[0009] Furthermore, a box door is hinged on the front surface of the screening box, and a material receiving hopper is fixedly penetrated through the top of the screening box.

[0010] Furthermore, a material receiving box is placed on the inner bottom wall of the screening box, and the material receiving box is adapted to the inner wall of the screening box.

[0011] Furthermore, sand guide plates are fixed on both left and right sides of the bottom of the U-shaped plate, and the sand guide plates are arranged obliquely.

[0012] Furthermore, the screening frame is fitted with the inner wall of the screening box, and the T-shaped card plate is an inverted "T"-shaped plate.

[0013] Furthermore, material guide plates are fixed on both the front and rear sides of the inner wall of the scattering box, and the material guide plates are located above the scattering rollers.

[0014] Furthermore, the number of the scattering rollers is two, and a plurality of scattering sticks are arranged outside the scattering rollers.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The machine-made sand production scatterer pours the machine-made sand into a scattering box, which is scattered by two relatively rotating scattering rollers. The scattered machine-made sand enters the receiving hopper and falls into the screening frame. Under the action of the falling gravity, the spring will expand and contract, so that the screening frame will shake up and down, which can further scatter the machine-made sand. The completely scattered machine-made sand will pass through the screen and fall into the receiving box for collection, while the unscattered machine-made sand will remain in the screening frame. After that, the screening frame can be taken out and the unscattered machine-made sand can be poured into the scattering box for further scattering, so as to achieve a better scattering effect.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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.

[0024] See also Figure 1-5 A scattering machine for machine-made sand production in this embodiment includes a base plate 1, a support frame 2 is fixedly installed on the top of the base plate 1, a scattering box 3 is installed on the support frame 2, a scattering mechanism is installed inside the scattering box 3, a support plate 8 is provided on the support frame 2, a screening box 7 is detachably installed on the top of the support plate 8, and a screening assembly is installed inside the screening box 7.

[0025] The bottom and top of the breaking box 3 are both open structures.

[0026] The scattering mechanism includes a drive motor 6 , which is mounted on the side wall of the scattering box 3 . A scattering roller 5 is fixedly connected to the output shaft of the drive motor 6 , and the scattering roller 5 is rotatably connected to the inside of the scattering box 3 .

[0027] The screening assembly includes a screening frame 11 and a U-shaped plate 15. A screen 13 is embedded and fixed at the bottom of the screening frame 11. T-shaped card plates 12 are fixedly connected to the left and right sides of the top of the U-shaped plate 15. Card slots 10 are provided on the left and right sides of the bottom of the front surface of the screening frame 11. The T-shaped card plate 12 is clamped in the inside of the card slot 10. Slide blocks 16 are fixed on the left and right sides of the U-shaped plate 15. The inside of the slider 16 is slidably connected to a slide bar 17. The slide bar 17 is fixedly installed in a mounting groove opened on the inner wall of the screening box 7. The outside of the slide bar 17 is provided with a spring 18 located at the bottom and top of the slide bar 16. The screening frame 11 fits the inner wall of the screening box 7, and the T-shaped card plate 12 is an inverted "T" shaped plate.

[0028] It is worth mentioning that the setting of the T-shaped card plate 12 has a restrictive effect on the screening frame 11, thereby preventing the screening frame 11 placed on the top of the U-shaped plate 15 from falling off during the shaking process. After opening the box door 71, the screening frame 11 can be pulled to move the T-shaped card plate 12 out of the card slot 10, so that the screening frame 11 can be easily taken out.

[0029] It should be noted that, due to the elasticity of the spring 18 itself, the manufactured sand is discharged into the receiving hopper 19 and then falls into the screening frame 11. Under the action of the falling gravity, the slider 16 will slide on the slide rod 17 and squeeze the spring 18 to expand and contract, thereby causing the screening frame 11 to shake up and down, which can further disperse the manufactured sand and improve the dispersion effect. At the same time, the undispersed manufactured sand can be screened out to facilitate the dispersion process again.

[0030] See also Figure 3 A box door 71 is hinged on the front surface of the screening box 7, a material receiving hopper 19 is fixed through the top of the screening box 7, and a material receiving box 9 is placed on the inner bottom wall of the screening box 7, and the material receiving box 9 is adapted to the inner wall of the screening box 7.

[0031] In this embodiment, sand guide plates 14 are fixed to both left and right sides of the bottom of the U-shaped plate 15, and the sand guide plates 14 are inclined.

[0032] The sand guide plate 14 is provided to guide the machine-made sand screened out, so that the machine-made sand falls into the material receiving box 9 and is collected.

[0033] See also Figure 4 , Figure 5 A material guide plate 4 is fixed on both the front and rear sides of the inner wall of the scattering box 3, and the material guide plate 4 is located above the scattering roller 5. There are two scattering rollers 5, and a plurality of scattering sticks 51 are arranged outside the scattering roller 5.

[0034] It should be noted that, by setting two relatively inclined guide plates 4, the machine-made sand poured into the scattering box 3 falls between the scattering rollers 5, and can be scattered by the two relatively rotating scattering rollers 5 in cooperation with the scattering rod 51.

[0035] The working principle of the above embodiment is as follows: when in use, after pouring the machine-made sand into the scattering box 3, the scattering roller 5 is driven to rotate by the driving motor 6, so that the two relatively rotating scattering rollers 5 can cooperate with the scattering rod 51 to scatter the machine-made sand, and the machine-made sand after being scattered is discharged and falls into the receiving hopper 19, thereby falling into the screening frame 11. Under the action of gravity of falling, the slider 16 will slide on the slide rod 17 and squeeze the spring 18 to expand and contract, so that the screening frame 11 will shake up and down, which can further scatter the machine-made sand. The machine-made sand after being completely scattered will pass through the screen 13 and fall into the receiving box 9 for collection, while the machine-made sand that has not been scattered will remain in the screening frame 11. Then, the box door 71 is opened, and the screening frame 11 can be pulled to take the screening frame 11 out of the screening box 7, and the machine-made sand that has not been scattered is poured into the scattering box 3 for scattering again, so as to ensure the scattering effect and make the scattering effect better.
