Description

Technical Field

[0001] The present application belongs to the field of sand and gravel processing equipment, and specifically, relates to an inlet assembly, an air separation box and a machine-made sand equipment. Background Art

[0002] The air separation box is an important part of the machine-made sand equipment, which is mainly used for the stone powder separation of the mixed materials. That is, the mixed materials after the raw materials are crushed by the crusher enter the air separation box for separation, and the materials after the stone powder is removed are screened by the vibrating screen at the rear end to obtain the finished machine-made sand with qualified stone powder content.

[0003] like Figure 1 As shown, there is usually a fixed guide plate in the air separation box. Before the mixed material falls into the inner cavity of the air separation box, it will be blocked by the fixed guide plate to slow down the movement of the mixed material and redirect it to the air inlet of the air separation box, so that the air blown in from the air inlet will blow away the dust in the material, and then the raised dust will be sucked away from the dust suction port.

[0004] However, when the moisture content of the mixed material is high or the mixed material is of excessive particle size, material accumulation is likely to occur at the feed port, and the feed port may even be blocked. Once blocked, the machine can only be shut down immediately, and the accumulated material must be cleaned manually, resulting in low production efficiency. Summary of the invention

[0005] The purpose of the present application is to provide a feed inlet assembly, a wind separation box and a machine-made sand device to avoid material accumulation and blockage at the feed inlet and improve production efficiency.

[0006] To achieve the above objectives, the present application provides, on one hand, a feed inlet assembly, the feed inlet assembly comprising:

[0007] The material inlet pipe body surrounds and defines a material flow channel, and the material flow channel includes a channel outlet entering the air separation box;

[0008] A movable guide plate is located below the material port pipe body, the movable guide plate extends laterally and at least partially blocks the channel outlet; and

[0009] The elastic pull rod assembly elastically connects the movable guide plate and the material port pipe body.

[0010] In some embodiments, the inlet assembly includes:

[0011] The guide plate fixed guide rail extends vertically and is fixedly arranged. The outer end of the movable guide plate can slide vertically along the guide plate fixed guide rail. The inner end of the movable guide plate is connected to the elastic pull rod assembly.

[0012] In some embodiments, a limit baffle is provided at the bottom end of the guide plate fixing rail.

[0013] In some embodiments, the elastic tie rod assembly includes:

[0014] The first tie rod section is connected to the material inlet pipe body;

[0015] a second tie rod section connected to the inner end of the movable deflector; and

[0016] The tension spring vertically connects the first pull rod section and the second pull rod section.

[0017] In some embodiments, the inlet assembly includes:

[0018] The pull rod fixing guide rail extends vertically and is fixedly arranged, and the second pull rod section slides vertically along the pull rod fixing guide rail.

[0019] In some embodiments, the guide plate fixing rail and the pull rod fixing rail are both fixedly mounted on the air separation box.

[0020] In some embodiments, the material inlet tube body is a rectangular tube, the movable guide plate is a rectangular plate, and elastic pull rod assemblies are provided at both ends of the rectangular plate in the length direction.

[0021] In some embodiments, the inlet assembly includes:

[0022] The upper ear seat is installed on the top of the material port pipe body, and the elastic pull rod assembly is connected to the upper ear seat.

[0023] The second aspect of the present application protects a wind separation box, which also includes the above-mentioned inlet assembly, and the inlet assembly is arranged adjacent to the air inlet of the box body.

[0024] The third aspect of the present application protects a machine-made sand device, which includes the above-mentioned air separation box.

[0025] In the technical solution of the present application, since the movable guide plate in the feed port assembly of the present application is elastically connected to the feed port pipe body through an elastic pull rod assembly, and the movable guide plate at least partially blocks the channel outlet from below, before the material passes through the material flow channel and enters the air separation box, the impact of the falling material can change the position of the movable guide plate until the movable guide plate reaches a force balance state again. For example, when the moisture content of the falling material is high or the particle size is super large, that is, when the impact force of the falling material is large, the equilibrium position of the movable guide plate will be moved downward, thereby increasing the area of ​​the channel outlet, and then accelerating the rate at which the material enters the air separation box. Therefore, the feed port assembly of the present application can avoid material accumulation and blockage at the feed port and improve production efficiency.

[0026] Other features and advantages of the embodiments of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0044] The feed inlet assembly, the air separation box and the machine-made sand equipment according to the present application are described below with reference to the accompanying drawings.

[0045] The present application discloses a novel feed inlet assembly, such as Figure 2 and Figure 3 As shown, the inlet assembly 100 in a specific embodiment includes:

[0046] The material inlet pipe body 110 is surrounded and defines a material flow channel, and the material flow channel includes a channel outlet 111 entering the air separation box;

[0047] A movable guide plate 120 is located below the material port tube body 110, and the movable guide plate 120 extends laterally and at least partially blocks the channel outlet 111; and

[0048] The elastic pull rod assembly elastically connects the movable guide plate 120 and the material inlet pipe body 110 .

[0049] Specifically, see Figure 2 and Figure 3 , the movable guide plate 120 in the feed port assembly 100 of the present application is elastically connected to the feed port tube body 110 through an elastic pull rod assembly, and at least partially blocks the channel outlet 111. Before the material passes through the material flow channel and enters the air separation box, the falling material will first be blocked by the movable guide plate 120 to slow down the speed of the material entering the air separation box and redirect it to the air inlet of the air separation box to improve the air separation effect. When there is too much incoming material, the material will accumulate on the movable guide plate 120. After the accumulated material exceeds a certain volume or mass, the position of the movable guide plate 120 changes due to gravity until the movable guide plate 120 reaches a force balance state again. For example, when the moisture content of the falling material is high or the particle size is super-large, the rate at which the material accumulates on the movable guide plate 120 is accelerated. After the accumulated material exceeds a certain volume or mass, the weight of the material causes the equilibrium position of the movable guide plate 120 to move downward, thereby increasing the area of ​​the channel outlet 111, see. Figure 4 and Figure 6 and Figure 5 and Figure 7 , and speed up the rate at which the material enters the air separation box, and reduces the amount of material accumulation on the movable guide plate 120. Therefore, compared with the fixed setting method of the fixed guide plate F in the prior art, the feed inlet assembly 100 of the present application can avoid material accumulation and blockage at the feed inlet, and improve production efficiency.

[0050] Of course, those skilled in the art will appreciate that the movement of the movable deflector 120 is not limited to the up-and-down movement shown in the figure, and may also be other movement such as pivoting.

[0051] In this embodiment, if Figure 2 and Figure 3 As shown, the inlet assembly 100 includes:

[0052] The guide plate fixed rail 141 extends vertically and is fixedly arranged. The outer end of the movable guide plate 120 can slide vertically along the guide plate fixed rail 141, and the inner end of the movable guide plate 120 is connected to the elastic pull rod assembly.

[0053] Specifically, see Figure 2 Such a configuration is beneficial to the stable movement of the movable guide plate 120 , has a simple structure, is highly practical and can improve the reliability of the feed port assembly 100 .

[0054] In this embodiment, if Figure 2 As shown, a limit baffle 150 is provided at the bottom end of the guide plate fixing rail 141 .

[0055] Specifically, see Figure 2 Due to the obstruction of the limit baffle 150 at the bottom of the guide plate fixed rail 141, the movable guide plate 120 cannot continue to move downward, that is, the movable guide plate 120 has a maximum stroke. Such a configuration is beneficial to protect the elastic member in the elastic pull rod assembly and prevent the elastic member from being stretched too long and failing.

[0056] Of course, the setting position of the limiting baffle 150 is not limited to the bottom end of the above-mentioned guide plate fixing rail 141, and can also be set on the air separation box body of the air separation box or other positions.

[0057] In this embodiment, if Figure 2 and Figure 3 As shown, the elastic pull rod assembly includes:

[0058] The first tie rod section 112a is connected to the material inlet pipe body 110;

[0059] A second tie rod section 122 connected to the inner end of the movable guide plate 120; and

[0060] The tension spring 130 vertically connects the first pull rod section 112 a and the second pull rod section 122 .

[0061] Specifically, see Figure 2 and Figure 3, the first rod section 112a and the second rod section 122 both have a certain length, and the tension spring 130 vertically connects the first rod section 112a and the second rod section 122, so that the tension direction of the tension spring 130 can be parallel to the extension direction of the first rod section 112a and the second rod section 122, thereby ensuring that the force direction of the movable guide plate 120 is consistent with the movement direction. Therefore, such a setting has a simple structure and is conducive to improving the stability of the movement of the movable guide plate 120 and the reliability of the inlet assembly 100.

[0062] In this embodiment, if Figure 3 As shown, the inlet assembly 100 includes:

[0063] The pull rod fixing guide rail 142 extends vertically and is fixedly arranged, and the second pull rod section 122 slides vertically along the pull rod fixing guide rail 142 .

[0064] Specifically, see Figure 3 Such a configuration is beneficial to the stable movement of the movable guide plate 120 , has a simple structure, is highly practical and can improve the reliability of the feed port assembly 100 .

[0065] In this embodiment, if Figures 4 to 7 As shown, the guide plate fixing rail 141 and the pull rod fixing rail 142 are both fixedly installed on the air separation box.

[0066] Specifically, such an arrangement has a simple structure and is easy to manufacture.

[0067] Of course, those skilled in the art will appreciate that the location of the guide plate fixing rail 141 and the pull rod fixing rail 142 is not limited to the above-mentioned air separation box, but may also be the material inlet pipe body 110 .

[0068] In this embodiment, if Figure 2 and Figure 3 As shown, the material inlet pipe body 110 is a rectangular tube, the movable guide plate 120 is a rectangular plate, and elastic pull rod assemblies are provided at both ends of the rectangular plate in the length direction.

[0069] Specifically, see Figure 3 Such a configuration is beneficial to the force balance of the movable guide plate 120, thereby further improving the movement stability of the movable guide plate 120.

[0070] Of course, the arrangement of the elastic pull rod assembly is not limited to the above-mentioned arrangement at both ends of the length direction of the rectangular plate, and can also be arranged symmetrically about the central axis of the movable guide plate 120. The shape of the movable guide plate 120 is also not limited to the above-mentioned rectangle, and can also be other shapes such as a circle. The shape of the inlet pipe body 110 is also not limited to the above-mentioned rectangular tube, and can also be a circular tube, etc.

[0071] In this embodiment, as shown in Figure 2 and Figure 3 , the feed inlet assembly 100 includes:

[0072] The upper ear seat 112 is installed at the top of the feed port pipe body 110, and the elastic pull rod assembly is connected to the upper ear seat 112.

[0073] Specifically, referring to Figure 2 and Figure 3 , with such a setting, the structure is simple, convenient for processing, and beneficial to the disassembly and assembly of the elastic pull rod assembly.

[0074] This application also protects an air separation box. As shown in Figures 4 to 7 , an air separation box in a specific embodiment further includes the above-mentioned feed inlet assembly 100, and the feed inlet assembly 100 is adjacently arranged to the air inlet 210 of the box body.

[0075] Specifically, referring to Figures 4 to 7 , after the material is redirected and conveyed to the air inlet 210 of the box body, the air blown in from the air inlet 210 of the box body can disperse the dust in the material, and then the lifted dust is sucked away by the dust suction port of the air separation box body. Among them, this air separation box has all the technical effects brought by the above-mentioned feed inlet assembly 100, which will not be elaborated here.

[0076] This application also protects a mechanism sand equipment. A mechanism sand equipment in a specific embodiment includes the above-mentioned air separation box.

[0077] Specifically, during the process of the material entering the air separation box from the diffusion chute of the mechanism sand equipment, when there is a situation of material accumulation in the feed inlet assembly 100, the movable deflector 120 can automatically adjust the discharging speed and clean the accumulated material, thoroughly solving the industry problem of affecting the normal production of the equipment due to material blockage. At the same time, it can avoid the shutdown loss and manual material cleaning work caused by material blockage, reduce the work intensity, and improve the work efficiency.
