Description

Technical Field

[0001] This utility model relates to the technical field of foundry sand recycling devices, and more specifically, to a sand recycling device with residual sand collection function. Background Technology

[0002] After the casting is completed, the casting sand needs to be recycled, which requires a sand recycling device. Currently, commercially available sand recycling devices mainly include a hopper, a conveying mechanism, a tilting mechanism, and a sand box. The hopper, conveying mechanism, and tilting mechanism are all fixed to the ground. The upper end of the hopper is connected to the bottom of the hopper, and the lower end of the hopper extends above the conveying mechanism. The sand box is connected to the tilting mechanism. When the sand recycling device is working, the tilting mechanism drives the sand box to tilt, causing the sand containing the casting to be poured into the hopper. After the sand and casting enter the hopper, the casting and sand are separated within the hopper. The sand in the bin can fall into the hopper through the grid holes at the bottom of the bin. The hopper then guides the sand to the conveying mechanism, which transports the sand to the sand storage box. However, during the process of the sand box pouring sand into the bin, when there is a lot of sand in the sand box and the sand box is initially pouring sand into the bin, or when the sand remaining in the sand box gradually decreases and the impact force of the sand being poured into the bin gradually decreases, some sand will not be able to enter the bin and will fall outside the bin. The sand will accumulate in the gap between the bin and the tipping mechanism, which not only requires regular cleaning by the staff, causing inconvenience to the staff, but also wastes sand. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sand recycling device with residual sand collection function, which can prevent sand from accumulating in the gap between the hopper and the tipping mechanism under the action of the collection trough, and can also prevent sand waste.

[0004] This utility model provides a sand recycling device with residual sand collection function, including a silo, a hopper, a conveying mechanism, a tilting mechanism, and a sand box; the silo, conveying mechanism, and tilting mechanism are all fixed on the ground, the upper end of the hopper is connected to the bottom of the silo, the lower end of the hopper extends to the top of the conveying mechanism, the sand box is connected to the tilting mechanism, and the tilting mechanism is used to drive the sand box to tilt so that the sand in the sand box is poured into the silo; the sand recycling device also includes a collection trough; the collection trough is welded and fixed to the outer wall of the silo facing the tilting mechanism, and the inner side of the collection trough forms a collection cavity with an open upper end, and the side wall of the silo is provided with an inlet for connecting the collection cavity and the inner cavity of the silo, and the collection cavity is used to collect residual sand falling from the sand box.

[0005] By adopting the above-mentioned structure, this utility model enables the collection of sand. During the process of the sand box pouring sand into the silo, if some sand cannot be poured into the silo, it can fall into the collection trough. In other words, the collection trough can collect the sand, and the sand entering the collection trough can enter the silo through the collection chamber and the feed inlet. This avoids the sand from accumulating in the gap between the silo and the tilting mechanism and avoids the waste of sand.

[0006] In one possible implementation, the lower edge of the feed inlet is connected to the lower edge of the collection chamber. With this structure, after the excess sand on the sand box falls into the collection chamber, the lower edge of the feed inlet is connected to the lower edge of the collection chamber, which allows the sand in the collection chamber to enter the inner cavity of the hopper more smoothly through the feed inlet, thus avoiding the sand from getting stuck at the junction of the collection chamber and the feed inlet. In other words, it can effectively prevent the sand from lingering at the junction of the collection chamber and the feed inlet.

[0007] In one possible implementation, the bottom edge of the collecting trough gradually slopes downward from the side furthest from the silo toward the side closest to the silo. With this structure, as the bottom edge of the collecting trough gradually slopes downward from the side furthest from the silo toward the side closest to the silo, the sand that falls from the sand box into the collecting chamber can be guided more smoothly by the bottom edge into the inner cavity of the silo through the feed inlet, which facilitates the recovery of the sand and effectively prevents the sand from accumulating on the bottom of the collecting trough.

[0008] In one possible implementation, the side of the collecting trough away from the silo gradually slopes from bottom to top away from the silo. By adopting this structure, since the side of the collecting trough away from the silo gradually slopes from bottom to top away from the silo, the opening width of the collecting chamber can be increased. This makes it easier and more reliable for the collecting chamber to receive the excess sand falling from the sand box. In addition, after the sand falls onto the inner wall of this side, the sand can move more smoothly to the bottom edge of the collecting trough under the guidance of this side and smoothly enter the inner cavity of the silo through the feed inlet after being guided by the bottom edge.

[0009] In one possible implementation, support plates are welded and fixed to the outer walls at both ends of the trough, and both support plates are welded and fixed to the outer wall of the silo. A support column is vertically welded and fixed to the middle of the lower end face of each support plate, and the lower end of the support column is supported on the ground and fixed to the ground. With this structure, the support plates are welded and fixed to both the trough and the silo, thereby improving the fixing firmness and reliability of the trough and the silo. The support columns provide vertical support to the support plates and the trough, thereby improving the load-bearing capacity of the trough and preventing it from bending downwards.

[0010] In one possible implementation, a support bar is welded and fixed to the outer bottom of the collection trough. The support bar extends from front to back, and its front and rear ends are respectively welded and fixed to the inner sidewall of one of the support columns. By setting the support bar, the support bar can provide reliable vertical support for the collection trough, so as to further prevent the collection trough from bending and deforming downward.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figure 1-3As shown in the figure, this application discloses a sand recycling device with residual sand collection function, including a silo 1, a hopper 2, a conveying mechanism 3, a tilting mechanism 4, and a sand box 5; the silo 1, the conveying mechanism 3, and the tilting mechanism 4 are all fixed on the ground 6, the upper end of the hopper 2 is connected to the bottom of the silo 1, the lower end of the hopper 2 extends to the top of the conveying mechanism 3, the sand box 5 is connected to the tilting mechanism 4, and the tilting mechanism 4 is used to drive the sand box 5 to tilt so that the sand in the sand box 5 is poured into the silo 1; the sand recycling device also includes a collection trough 7; the collection trough 7 is welded and fixed to the outer wall of the silo 1 on the side facing the tilting mechanism 4, and the inner side of the collection trough 7 forms a collection cavity 71 with an open upper end, and the side wall of the silo 1 is provided with an inlet 11 for connecting the collection cavity 71 and the inner cavity of the silo 1, and the collection cavity 71 is used to collect residual sand falling from the sand box 5.

[0019] The lower edge of the feed inlet 11 is connected to the lower edge of the collection chamber 71. With this structure, after the residual sand on the sand box falls into the collection chamber, the lower edge of the feed inlet is connected to the lower edge of the collection chamber, so that the sand in the collection chamber can enter the inner cavity of the hopper more smoothly through the feed inlet, so as to avoid the sand getting stuck at the junction of the collection chamber and the feed inlet. In other words, it can effectively prevent the sand from being stuck at the junction of the collection chamber and the feed inlet.

[0020] The bottom edge 72 of the collecting trough 7 gradually slopes downward from the side away from the hopper 1 towards the side closer to the hopper 1. With this structure, since the bottom edge of the collecting trough gradually slopes downward from the side away from the hopper towards the side closer to the hopper, after the residual sand on the sand box falls into the collecting cavity, the sand can enter the inner cavity of the hopper more smoothly through the feed inlet under the guidance of the bottom edge, so as to facilitate the recovery of the sand and effectively prevent the sand from being stuck on the bottom of the collecting trough.

[0021] The side 73 of the collecting trough 7 away from the silo 1 gradually slopes from bottom to top towards the side away from the silo 1. By adopting this structure, since the side of the collecting trough away from the silo gradually slopes from bottom to top towards the side away from the silo, the opening width of the collecting chamber can be increased. This makes it easier and more reliable for the collecting chamber to receive the excess sand falling from the sand box. In addition, after the sand falls onto the inner wall of this side, the sand can move more smoothly to the bottom edge of the collecting trough under the guidance of this side and smoothly enter the inner cavity of the silo through the feed inlet after being guided by the bottom edge.

[0022] Support plates 74 are welded and fixed to the outer walls at both ends of the material collection trough 7. Both support plates 74 are welded and fixed to the outer wall of the hopper 1. A support column 75 is vertically welded and fixed to the middle of the lower end face of each support plate 74. The lower end of the support column 75 is supported on the ground 6 and fixed to the ground 6. With this structure, the support plates are welded and fixed to both the material collection trough and the hopper, which improves the fixation firmness and reliability of the material collection trough and the hopper. The support columns provide vertical support to the support plates and the material collection trough, thereby improving the load-bearing capacity of the material collection trough and preventing it from bending downwards.

[0023] A support bar 76 is welded and fixed to the outer bottom of the collection trough 7. The support bar 76 extends from front to back, and the front and rear ends of the support bar 76 are respectively welded and fixed to the inner side wall of one of the support columns 75. Through the setting of the support bar, the support bar can provide reliable vertical support for the collection trough, so as to further prevent the collection trough from bending and deforming downward.

[0024] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
