Technical Field
[0001] The utility model belongs to the technical field of building construction, in particular to a splash-proof sand and gravel crusher for building construction. Background Art
[0002] Sand and gravel refer to a loose mixture of sand particles and crushed stone. In geology, mineral or rock particles with a particle size of 0.074 to 2 mm are called sand, and particles with a particle size greater than 2 mm are called gravel or angular gravel. The difference between the two lies in the degree of roundness. During construction, sand and gravel will be crushed into fine sand and used as infrastructure materials.
[0003] At present, when sand and gravel are fed into a sand and gravel crusher for crushing, if too much sand and gravel is filled in at one time, the sand and gravel are easily stuck in the feed port, causing accumulation and unable to continue falling for crushing. Secondly, during the crushing process of sand and gravel, some sand and gravel are easily splashed out from the feed port, causing injuries to workers. Utility Model Content

DETAILED DESCRIPTION
[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0023] like Figure 1-6 As shown, the utility model provides a technical solution: a splash-proof sand and gravel crusher for construction construction, including a shell 1, a support leg 2 is connected to the bottom of the shell 1, a feed bin 3 is installed above the shell 1, a rotating frame 15 is rotatably connected to the feed bin 3, the rotating frame 15 is cross-shaped as a whole, and a stirring rod 31 is connected to the rotating frame 15. The rotating frame 15 is driven to rotate by the first motor 5, so that the stirring rod 31 can stir the sand and gravel accumulated inside the feed bin 3, prompting the sand and gravel to flow out from the discharge port 16, so that the sand and gravel crusher can work normally.
[0024] A mounting plate 4 is connected to the shell 1, a discharge port 24 is opened at the bottom of the shell 1, and an anti-slip pad 25 is connected to the bottom of the support leg 2. The crushed sand and gravel particles will flow out from the discharge port 24, and the anti-slip pad 25 under the support leg 2 can increase the friction with the ground, thereby preventing the support leg 2 from sliding.
[0025] A first motor 5 is mounted on the mounting plate 4, and the output shaft of the first motor 5 is connected to a driving wheel 6. There are two driving wheels 6, and a first synchronous belt 7 and a second synchronous belt 8 are installed respectively. The driving wheel 6 is connected to a driven wheel 9 through the second synchronous belt 8. The driven wheel 9 is connected to a main gear 10, and the main gear 10 is meshed with a sub-gear 11. The main gear 10 and the sub-gear 11 are both connected at the center with a rotating rod 12, and a crushing tooth 13 is provided on the rotating rod 12. The driving wheel 6 is connected to an auxiliary wheel 14 through a first synchronous belt 7, and the auxiliary wheel 14 is connected to a rotating frame 15. The rotating rod 12 is rotatably connected to the inside of the housing 1. The diameters of the driven wheel 9 and the auxiliary wheel 14 are larger than those of the driving wheel 6. Through the meshing of the main gear 10 and the sub-gear 11, the two crushing teeth 13 can rotate synchronously and in opposite directions, thereby crushing the filled sand and gravel. The design that the driven wheel 9 and the auxiliary wheel 14 have larger diameters than the driving wheel 6 can ensure normal transmission.
[0026] A discharge port 16 is provided on the feed bin 3, and a feed pipe 17 is connected to the feed bin 3. A guide groove 26 is provided above the feed pipe 17, and open grooves 27 are provided on both sides of the feed pipe 17. A limiting groove 28 is provided on the inner wall of the feed pipe 17. The baffle 23 slides in the open groove 27, and the curved rod 22 slides in the guide groove 26. The design of the curved rod 22 bending and passing through the feed pipe 17 can avoid collision of the rack 21 during movement, so that the baffle 23 can slide smoothly to complete the blocking of splashing gravel.
[0027] A protective plate 18 is connected to the feed pipe 17, and a second motor 19 is installed on the protective plate 18. The output shaft of the second motor 19 is connected to a driving gear 20, and the driving gear 20 is meshed with a rack 21. One end of the rack 21 is connected to a curved rod 22, and the curved rod 22 passes through the feed pipe 17 and is connected to a baffle 23. A limiting bar 29 is connected below the baffle 23, and the limiting bar 29 slides in the limiting groove 28. A connecting bar 30 is connected to one side of the rack 21. A T-shaped groove is provided on the inner wall of the protective plate 18, and the connecting bar 30 is slidably connected to the T-shaped groove on the inner wall of the protective plate 18. The sliding of the limiting bar 29 in the limiting groove 28 and the sliding of the curved rod 22 in the guide groove 26 can respectively guide and limit the movement of the baffle 23, so that the baffle 23 can move smoothly and prevent the baffle 23 from slipping.
[0028] The working principle of this utility model is:
[0029] By starting the second motor 19 to rotate the driving gear 20, the driving gear 20 pushes the rack 21 to move, prompting the curved rod 22 to move in the guide groove 26 and at the same time push the baffle 23 to slide, thereby opening the feed pipe 17, and then filling the sand and gravel from the feed pipe 17 into the interior of the shell 1, and rotating the driving gear 20 in the opposite direction, so that the baffle 23 closes the feed pipe 17 to prevent the crushed gravel from splashing everywhere. By starting the first motor 5 to rotate the driving wheel 6, the driving wheel 6 can drive the driven wheel 9 through the second synchronous belt 8 to prompt the main gear 10 to rotate, so that the engagement between the main gear 10 and the sub-gear 11 makes the two crushing teeth 13 rotate synchronously to crush the filled sand and gravel. At the same time, the driving wheel 6 can drive the auxiliary wheel 14 to rotate through the first synchronous belt 7, prompting the rotating frame 15 to rotate in the feed bin 3, so that the stirring rod 31 stirs the sand and gravel in the feed bin 3 to prevent the sand and gravel from accumulating and blocking the discharge port 16, and the crushed sand and gravel particles will flow out from the discharge port 24.
