[0001] This utility model relates to the field of sand making machine technology, specifically a double roller sand making machine. Background Technology

[0002] Safety is a top priority for both the government and businesses in the manufacturing sector. Despite this emphasis, accidents still occur frequently, causing significant headaches for companies. Reducing safety incidents from a technical perspective is a crucial management issue. To address the issue of the rotating bases on both sides of the roller crusher being in motion and shaking during production, and the frequent movement of personnel on both sides to observe the crushing process, safety protection devices have been added to both sides of the roller crusher to reduce the occurrence of accidents.

[0003] The movable bearing base of a double-roll crusher is constantly in motion and vibrating during the sand making process. Many crushers on the market lack safety protection devices, which can easily lead to accidents and personal injury. Therefore, we added protective devices to the sides of the crusher where workers frequently walk, providing protection. Utility Model Content

[0023] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0025] like Figures 1-4As shown, this utility model provides a technical solution: a double-roller sand making machine, comprising a base 1, a motor 101 mounted on the top of the base 1, and a protective box 2, characterized in that: a coupling is installed at the output end of the motor 101, and a gearbox 102 is installed at the other end of the coupling; a crushing roller 4 is rotatably mounted on one end of the gearbox 102, and the other end of the crushing roller 4 penetrates through one side of the outer wall of the protective box 2 and is connected to the top of the base 1 through a mounting seat; movable holes 201 are opened on the outer sides of both ends of the protective box 2, and the other crushing roller 4 is located on the inner wall of the movable hole 201; a quantitative feeding component 3 is set at the top of the protective box 2, and the quantitative feeding component 3 is used to quantitatively input the sand making raw material into the protective box 2; a hydraulic clamping component 5 is set on one side of the top of the base 1 and connected to the other crushing roller 4, and the hydraulic clamping component 5 is used to move the other crushing roller 4; and a protective component 6 is set on both sides of the base 1 for protecting the sand making machine. It should be clearly understood that in this embodiment, the base 1 on the motor 101 and the base on the roller are detachable. The two bases 1 are connected by bolts, and vibration-damping rubber pads are placed under both bases 1 to reduce the vibration transmitted from the main unit to the motor 101, thereby extending the service life of the motor 101 and reducing the failure rate (such as wire detachment, burn-out, etc.). It should also be clearly understood that, as mentioned above, the output end of the motor 101 is connected to the gearbox 102 through a coupling. The gearbox 102 uses different gear combinations to generate speed changes, thereby achieving the purpose of adjusting the speed. Since the gearbox 102 is prior art, it will not be described in detail here.

[0026] like Figure 1 and Figure 2 As shown, in order to better crush the raw materials, a quantitative feeding component 3 is installed on the top of the protective box 2 to achieve the effect of sand making after crushing. Specifically, the quantitative feeding component 3 includes a support leg 302, which is connected to the top of the protective box 2. A feeding hopper 301 is installed on the top of the support leg 302. An installation block 303 is installed on the outer side of one end of the feeding hopper 301. A pneumatic rod 304 is installed between the installation blocks 303. A discharge plate 305 is installed on the telescopic end of the pneumatic rod 304. The discharge plate 305 is adapted to the discharge port of the feeding hopper 301, and one end of the discharge plate 305 is hinged to the outer side of the feeding hopper 301. It should be clear that... Figure 2As can be seen, the bottom of the feed hopper 301 has a semi-circular arc structure, and the outer side of the feed hopper 301 is fitted with a discharge plate 305 that can prevent material discharge via a hinge. The outer wall of the discharge plate 305 is connected to the telescopic end of the pneumatic rod 304. In order to fix the pneumatic rod 304, an mounting block 303 is installed on the outer wall of the pneumatic rod 304 and connected to the feed hopper 301. Therefore, the pneumatic rod 304 can drive the opening and closing of the discharge plate 305, thereby realizing the quantitative feeding of the raw material from the feed hopper 301 into the crushing roller 4 in the protective box 2 for crushing.

[0027] like Figures 1 to 4 As shown, in order to obtain sand of different diameters, a mechanism is provided on the base 1 to control the gap between the crushing rollers 4. A hydraulic clamping assembly 5 is used to move another crushing roller 4 within a moving hole 201 in the protective box 2. Specifically, the hydraulic clamping assembly 5 includes a cylinder 501, which is mounted on one side of the top of the base 1. A connecting rod is mounted on the outer wall of the telescopic end of the cylinder 501, and a contraction spring 502 is provided on the outer wall of the connecting rod. A sliding seat 503 is provided at the top of the base 1, located on both sides of the protective box 2. A bearing seat 504 is slidably mounted on the top of the sliding seat 503. One end of the bearing seat 504 is connected to the connecting rod, and the top of the bearing seat 504 is connected to the mounting base of the other crushing roller 4. It should be clear that in this embodiment, the hydraulic clamping assembly 5 is connected to the cylinder 501 via an external pneumatic source. The telescopic end of the cylinder 501 can drive the connected connecting rod to move. Since one end of the connecting rod is connected to the mounting seat of the crushing roller 4, and as mentioned above, the mounting seat of the crushing roller 4 is connected to the bearing seat 504, which is connected to the sliding seat 503, the crushing roller 4 can move within the moving hole 201 opened on the protective box 2, thereby realizing the production of sand of different diameters.

[0028] like Figure 3As shown, to prevent people from walking on both sides while the sand making machine is working, protective components 6 are installed on both sides of the base 1. These protective components 6 prevent personnel from coming into contact with the machine's braking parts. Specifically, the protective components 6 include a bearing sliding base 601, which is connected to the bearing seat 504. A protective plate 604 with a U-shaped structure is installed at the bottom of the bearing sliding base 601. A connecting plate 603 is welded to the inner side of the protective plate 604, and a fixing plate 602 is connected to the outer side of the connecting plate 603 via connecting bolts 606. The fixing plate 602 is connected to the outer side of the base 1. A wear-resistant steel plate 605 is installed inside the bottom of the U-shaped groove of the protective plate 604, and a protective cover plate 607 is installed on the outer side of the protective plate 604. It should be clear that in this embodiment, the fixing plate 602 is welded to the base 1, while the connecting plate 603 is welded to the protective plate 604. Then, the protective plate 604 is connected to the fixing plate 602 using connecting bolts 606. The protective plate 604 connected by connecting bolts 606 is easy to disassemble and maintain. It should also be clear that wear-resistant steel plates 605 are provided on the contact surfaces of the protective plate 604 and the bearing sliding base 601. The wear-resistant steel plates 605 increase the wear resistance between the protective plate 604 and the bearing sliding base 601. The wear-resistant steel plates 605 are made of alloy material, and a sliding groove is provided in the middle of the wear-resistant steel plate 605. Figure 3 As shown, an oil injection hole is provided on the top of the bearing sliding seat 601. The oil injection hole can increase the lubrication of the bearing sliding seat 601. It should also be clear that the protective cover plate 607 is located above the connecting bolt 606. The protective cover plate 607 protects the protective plate 604 and the bearing sliding seat 601, and at the same time prevents the workers from coming into contact with the braking part of the sand making machine.
