[0042] Figure 1 This is a schematic structural diagram of a new rod valve device according to an embodiment of the present utility model. Figure 1 As shown, and reference Figures 2 to 5 The embodiment of the present utility model provides a novel rod valve device. The novel rod valve device includes a plurality of rods 100 spaced apart in the horizontal direction, a frame 200, a third fixing plate 310, a baffle 400 and a discharge chute 500.
[0043] The rod 100 extends along a first direction.
[0044] The frame 200 is formed with a first passage extending vertically therethrough. The sidewalls of the frame 200 include first fixing plates 210 spaced apart along a first direction and second fixing plates 220 arranged along a second direction perpendicular to the first direction. At least one of the first fixing plates 210 is provided with a first insertion hole 211 extending along the first direction, so that the rods 100 can be inserted into the first insertion hole 211 in a one-to-one correspondence.
[0045] The third fixing plates 310 are spaced apart in the first direction on a side of the first fixing plate 210, which is provided with the first insertion hole 211, away from the first channel. The two second fixing plates 220 extend to either side of the third fixing plate 310 in the second direction, forming an opening between the first fixing plate 210 and the third fixing plate 310 for receiving slots 300. The third fixing plate 310 is provided with a second insertion hole 311, which is opposite to the first insertion hole 211.
[0046] The baffle 400 is disposed on the upper end of the receiving tank 300 to cover the upper opening of the receiving tank 300 .
[0047] The discharge chute 500 is fixedly connected to the lower end of the frame 200 and defines a second channel communicating with the first channel. The upper edge of the side wall of the discharge chute 500 near the second insertion hole 311 is connected to the lower bottom surface of the third fixing plate 310.
[0048] In this embodiment, during material transport, the material first passes through the first channel and then enters the second channel. The flow rate of the material through the first channel is controlled by controlling the position of the rod 100. Due to the gap between the rod 100 and the first insertion hole 211, small particles, dust, or water in the material may enter the receiving tank 300 through the gap between the rod 100 and the first insertion hole 211. A baffle 400 is provided on the upper portion of the receiving tank 300 to seal the upper opening of the receiving tank 300 and prevent dust and other materials from escaping from the upper end of the receiving tank 300.
[0049] The upper edge of the side wall of the discharge chute 500 of the present invention near the second insertion hole 311 is seamlessly connected to the lower bottom surface of the third fixed plate 310, so that the lower end of the receiving chute 300 is connected to the second channel, so that the dust and other materials that leak into the receiving chute 300 from the gap fall directly downward into the second channel, reducing the situation where small particles, dust or water enter the factory through the gap between the rod 100 and the first insertion hole 211 or the second insertion hole 311, thereby reducing the dust in the factory, simplifying the difficulty of cleaning the factory, and avoiding the situation where the equipment has a short service life due to excessive dust and affects the health of workers.
[0050] Moreover, by directly connecting the upper edge of the side wall of the discharge chute 500 close to the second insertion hole 311 to the lower bottom surface of the third fixed plate 310, the dust and other materials in the receiving trough 300 can directly fall downward into the second channel. The structure is simple and easy to manufacture, thereby reducing the production cost of the new rod valve device.
[0051] In some embodiments of the present invention, Figure 1 As shown, the baffle 400 may be connected to the second fixing plate 220 by fasteners.
[0052] In this embodiment, the baffle 400 is detachably connected to the second fixing plate 220 to facilitate cleaning of the receiving tank 300 .
[0053] Alternatively, in other embodiments of the present invention, the baffle 400 may be welded to the second fixing plate 220 .
[0054] Alternatively, in other embodiments of the present invention, the baffle 400 may be an integrally formed structure with the first fixing plate 210 , the second fixing plate 220 , and the third fixing plate 310 .
[0055] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the side wall of the discharge chute 500 close to the second insertion hole 311 is inclined toward the interior of the second channel.
[0056] In this embodiment, the material in the receiving tank 300 falls downward into the second channel under the influence of gravity, and the side walls are inclined to guide the material, so that the dust, small particles or moisture and other materials falling from the receiving tank 300 into the second channel can flow more smoothly into the second channel.
[0057] The side walls are inclined to provide a buffer for the material. When the material falls from the receiving trough 300 into the discharge trough 500, the inclined side walls can provide a buffer surface for the material, slowing down the falling speed and impact force of the material, and preventing the material from violently colliding and splashing in the discharge trough 500. This not only reduces the noise generated by the new rod valve device during the material transportation process, but also reduces the dust generated by the collision between the material and the discharge trough 500.
[0058] In some embodiments of the present invention, Figure 5 As shown, an extension plate 510 is formed on the upper edge of the side wall of the discharge chute 500 close to the second insertion hole 311 and extends in a direction away from the second channel.
[0059] In this embodiment, the end of the extension plate 510 away from the second channel is connected to the bottom of the third fixed plate 310. By providing the extension plate 510 to increase the connection area between the side wall and the third fixed plate 310, the connection between the side wall and the third fixed plate 310 is made more stable.
[0060] Moreover, the provision of the extension plate 510 increases the strength of the side wall of the discharge chute 500 connected to the third fixed plate 310 , thereby making the side wall less likely to deform, thereby improving the sealing between the side wall and the third fixed plate 310 .
[0061] In some embodiments of the present invention, Figure 5 As shown, both upper and lower ends of the first fixing plate 210 have flanges extending in a direction away from the first channel.
[0062] In this embodiment, the provision of the flange increases the strength of the first fixing plate 210 , thereby making the first fixing plate 210 less likely to deform, thereby improving the sealing performance of the receiving groove 300 and the first channel.
[0063] In some embodiments of the present invention, Figure 4 As shown, both upper and lower ends of the second fixing plate 220 have flanges extending in a direction away from the first channel.
[0064] In this embodiment, the provision of the flange increases the strength of the second fixing plate 220 , thereby making the second fixing plate 220 less likely to deform, thereby improving the sealing performance of the receiving groove 300 and the first channel.
[0065] In some embodiments of the present invention, Figure 5As shown, both upper and lower ends of the third fixing plate 310 have flanges extending in a direction away from the first channel.
[0066] In this embodiment, the provision of the flange increases the strength of the third fixing plate 310 , thereby making the third fixing plate 310 less likely to deform, thereby improving the sealing performance of the receiving groove 300 .
[0067] In some embodiments of the present invention, the gap between the rod 100 and the first insertion hole 211 is between 2 mm and 3 mm.
[0068] In this embodiment, the rod 100 is slidably connected to the first insertion hole 211. If the gap between the rod 100 and the first insertion hole 211 is too small, the rod 100 may have difficulty sliding due to excessive frictional resistance, or even become stuck. If the gap between the rod 100 and the first insertion hole 211 is too large, dust from the material can easily enter the receiving tank 300 through the gap between the rod 100 and the first insertion hole 211, resulting in excessive dust in the factory.
[0069] When the gap between the rod 100 and the first insertion hole 211 is set between 2 mm and 3 mm, the friction resistance between the rod 100 and the first insertion hole 211 can meet the movement of the rod 100 while avoiding the occurrence of excessive dust in the factory due to an excessively large gap.
[0070] In some embodiments of the present invention, a brush is provided on the inner peripheral wall of the first insertion hole 211 to cover the gap between the rod 100 and the first insertion hole 211 .
[0071] In this embodiment, during material conveying, some dust and other materials are prone to overflowing from the gap between the rod 100 and the first insertion hole 211. A brush is provided around the first insertion hole 211 so that the bristles cover the gap between the rod 100 and the first insertion hole 211, thereby reducing the amount of dust and other materials that overflow from the gap between the rod 100 and the first insertion hole 211. The length of the brush is greater than or equal to the gap between the rod 100 and the first insertion hole 211.
[0072] In some other embodiments of the present invention, a sealing ring is provided on the inner peripheral wall of the first insertion hole 211 .
[0073] In some embodiments of the present invention, the novel rod valve device includes a plurality of third fixing plates 310 spaced apart along the first direction, so that the accommodating grooves 300 are adjacent and spaced apart along the first direction.
[0074] In this embodiment, the two second fixing plates 220 extend to both sides of the outermost third fixing plate 310 in the second direction, respectively. A plurality of receiving grooves 300 are arranged adjacent to and spaced apart on the outer side of the frame 200. The amount of dust and other materials in the receiving grooves 300 that are farther away from the first channel is less, thereby further reducing the possibility of small particles, dust or water entering the factory through the gap between the rod 100 and the first insertion hole 211 or the second insertion hole 311.
[0075] In some embodiments of the present invention, Figure 5 As shown, the two first fixing plates 210 are each provided with a first insertion hole 211 corresponding to the rod 100, so as to improve the efficiency of adjusting the position of the rod and avoid deformation or even breakage of the rod due to excessive length.
[0076] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, in the first direction, every two oppositely disposed rods 100 are coaxially disposed, and the ends close to each other are in a frustum shape.
[0077] In this embodiment, the frustum-shaped design prevents damage to the rods 100 due to excessive pressure at the contact point when the two oppositely disposed rods 100 approach each other.
[0078] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the novel rod valve device further includes a handle 600 , which is fixedly connected to a side of the rod 100 away from the first channel, and is arranged perpendicular to the extension direction of the rod 100 .
[0079] In this embodiment, the handle 600 is fixedly connected to the side of the rod 100 away from the first channel, so that the operator can more conveniently control the movement of the rod 100, thereby improving work efficiency and convenience of operation.
[0080] In some embodiments of the present invention, the handle 600 and the rod 100 are integrally formed to prevent the handle 600 from becoming loose or even falling off during operation.
[0081] In some embodiments of the present invention, the handle 600 is provided with an anti-slip texture to improve stability and safety during operation.
[0082] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
