Abstract
Description
Technical Field
[0001] The invention relates to the field of waste steel recycling, and in particular to a shearing recycling device with a gantry shear. Background Art
[0002] After the scrap metal is recycled, various equipment is needed to cut and crush it for subsequent processing. Among them, the gantry shearing machine has the advantages of large shearing force and convenient use. It uses oil pressure to drive the cylinder to achieve shearing operation.
[0003] The general process of the existing gantry shears is to send the scrap steel to be sheared to the anvil, first control the hydraulic cylinder to press the pressure plate to press a section of the scrap steel, and then control another set of hydraulic cylinders to press down the scissors on the other side of the pressure plate to shear. Since the pressure plate and the scissors are not integrated, it is necessary to equip the pressure plate with a power source separately. In addition, in the subsequent scrap steel recycling and processing methods, since re-melting processing is mostly used, there is no requirement for the length of the scrap steel. However, if the plate or tube type scrap steel is easy to maintain the original shape, it can be refurbished by cutting, rust removal, sandblasting, and painting, or it needs to be briquette processed. Since the volume that the briquetting machine can process at one time is limited, there is a requirement for the shearing device to control the length and size of the shearing. Summary of the invention
[0004] In order to realize the integrated design of scissors and a pressure plate and control the length and size of the sheared material, the utility model designs a shearing and recycling device with a gantry shear, comprising: a feed bin, a gantry shear, a discharging conveyor belt, and a scrap iron briquetting machine arranged from right to left; the feed bin comprises enclosures arranged at the front and rear sides and a feed conveyor belt arranged in a left-right direction between the two enclosures; the left end of the feed conveyor belt is butted against the gantry shear; the right end of the discharging conveyor belt is located at the lower left of the gantry shear, the left end is located above the scrap iron briquetting machine, and the left end of the discharging conveyor belt is higher than the right end; the conveying rollers at both ends of the discharging conveyor belt are both stood on the ground through brackets; the scissors and the pressure plate of the gantry shear are an integrated structure, and a fixed-length plate for measuring the length of the waste material is provided under the scissors.
[0005] Preferably, the gantry shears include: a gantry, two hydraulic cylinders are installed on the top beam of the gantry, the plunger driven by the hydraulic cylinder passes through the top beam to drive the scissors arranged on the inner side of the gantry to move up and down, and the two sides of the scissors are clamped in the guide rails on the inner sides of the two columns of the gantry; two sleeves are provided on the right surface of the scissors, a spring is fixed on the top of the inner side of the sleeve, two guide columns are provided on the upper part of the pressing plate, the guide columns are inserted into the sleeves and fixed to the lower end of the spring; a chopping board is also provided under the pressing plate.
[0006] Preferably, a fixed-length plate that can be pulled out in the discharging direction is provided at the bottom of the cutting board.
[0007] Preferably, the side surface of the fixed-length board is L-shaped, and a length scale is provided on one side of the upper surface of the fixed-length board to measure the distance between the vertical board and the chopping board of the fixed-length board; the height of the vertical board is higher than the height of the chopping board.
[0008] Preferably, the bottom edge of the pressing plate is an arc edge, and the middle part of the bottom edge is slightly arched upwards.
[0009] Preferably, when the gantry shears are not shearing materials, the bottom of the pressing plate is always below the bottom of the scissors.
[0010] When the utility model is used, the metal waste is sent to the gantry shears through the feed bin. Since the pressure plate of the gantry shears is inserted into the sleeve on the rear surface of the scissors through the guide column on the upper part thereof and is fixed with the spring in the sleeve, when shearing, the fixed-length plate is first drawn out to the corresponding scale, and one end of the scrap steel is placed against the vertical plate of the fixed-length plate for shearing. When the scissors are pressed down, the pressure plate first presses the waste, and then the scissors cut the waste, so that the scrap steel pieces of the required length can be obtained. The scrap steel pieces are sent to the scrap iron briquetting machine through the discharging conveyor belt for briquetting, and then unloaded to the transfer vehicle for transportation away for subsequent recycling. The utility model is exquisitely designed, saves costs, and has improved practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] More specifically, when the gantry shears 1 are not shearing, the bottom of the pressing plate 16 is always below the bottom of the scissors 14. The elasticity of the pressing plate 16 can also prevent the scissors 14 from sticking to the scissors 14 when the scissors 14 are separated from the scrap steel. Example 2
[0021] like Figure 1-Figure 4As shown, the shearing and recovery device with gantry shears described in the utility model comprises: a feed bin 2, a gantry shear 1, a discharging conveyor belt 3 and a scrap iron briquetting machine 4 arranged from right to left; the feed bin 2 comprises enclosures 22 arranged at the front and rear sides and a feed conveyor belt 21 arranged in a left-right direction between the two enclosures; the left end of the feed conveyor belt 21 is butted against the gantry shear 1; the right end of the discharging conveyor belt 3 is located at the lower left of the gantry shear 1, and the left end is located above the scrap iron briquetting machine 4, and the left end of the discharging conveyor belt 3 is higher than the right end; the conveying rollers at both ends of the discharging conveyor belt 3 are both supported on the ground by brackets; the scissors 14 and the pressing plate 16 of the gantry shear 1 are an integrated structure, and a fixed-length plate 10 for measuring the length of the waste is provided below the scissors 14.

When the scissors are pressed down, the pressure plate first presses the waste, and then the scissors cut the waste, so that the scrap steel pieces of the required length can be obtained. The scrap steel pieces are sent to the scrap iron briquetting machine through the discharging conveyor belt for briquetting, and then unloaded to the transfer vehicle for transportation away for subsequent recycling. The utility model is exquisitely designed, saves costs, and has improved practicality.
