Description

Technical Field

[0001] The utility model relates to the technical field of mechanical residual material crushing and recovery, in particular to a residual material recovery, crushing and screening unit for mechanical processing. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. The production process of a machine refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of raw materials, production preparation, manufacturing of blanks, processing and heat treatment of parts, assembly and debugging of products, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production system with input and output.

[0003] When users perform mechanical processing on parts, a large amount of debris waste will be generated. In order to save costs, the debris powder that needs to be recycled will be utilized and processed, which requires the use of a recycling crushing and screening unit. However, most of the existing recycling crushing and screening units are relatively simple, and most of them are manually loaded and processed on the debris waste, which greatly increases the labor intensity of users. In addition, due to the large differences in particle diameters of the debris waste, the debris waste cannot be pre-screened. At the same time, after the debris waste is processed, the state of the debris is still in a loose particle form, and the screened debris waste cannot be squeezed, which makes it inconvenient for users to manually unload it.

[0004] For example, a waste recycling and reuse device for mechanical processing disclosed in Chinese patent publication number CN212633827U can adjust the height of the transport frame through the cooperation of the first slide, the first hydraulic cylinder, the movable seat and the first slider, so as to meet the feeding requirements of the transport frame for equipment of different heights, speed up the feeding rate of the scrap waste, and shorten the feeding time of the scrap waste. The driving source is provided by the motor, and then through the cooperation of the third articulated seat, the impact wheel, the pulley, the lifting column, the sliding sleeve and the reset spring, the connecting plate drives the screening frame to regularly vibrate and screen the scrap waste on the surface, and pre-screens the scrap waste with the same diameter, so as to facilitate the user to separately recycle the scrap iron with different diameters. Through the cooperation of the second hydraulic cylinder, the extrusion seat, the extrusion head and the buffer reset spring, the scrap waste in the extrusion box can be extruded into blocks, so as to facilitate the user to take the block scrap iron waste, and further speed up the recycling efficiency of the scrap iron.

[0005] The existing technology has the following problems:

[0006] When the above device is used for actual feeding and discharging of mechanical residues, it is easy to cause blockage during feeding and discharging because different mechanical residues have different sizes and irregular surfaces. In addition, the mechanical residues are heavy, and the oscillation of the oscillator is not enough to stir the mechanical residues, making maintenance complicated. Utility Model Content

[0007] The utility model provides a residual material recovery, crushing and screening unit for mechanical processing, so as to solve the problems raised in the above background technology.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is:

At this time, due to the connecting action of the adjusting screw, the other rotating shaft and the sleeve rotate, and then the downward pressure dredging piece at the bottom of the adjusting screw hits the mechanical residual material at the feed port, thereby ensuring the dredging of the feed port.

[0011] A further improvement of the technical solution of the utility model is that: the adjusting screw is vertically installed on the crankshaft connecting rod, the adjusting screw is threadedly connected to the crankshaft connecting rod, the adjusting screw is fixedly connected to the downward pressure clearing piece, and the adjusting screw is located directly above the feed port. The depths of the feed port and the recovery chamber are different in different crushers and different devices. After the rotation of the articulated rod one and the articulated rod two, due to the limitation of the length of the crankshaft connecting rod, it is impossible to ensure that the adjusting screw can descend to the bottom of the feed port. If this situation is encountered, the adjusting screw can be rotated to make the adjusting screw rise and fall on the crankshaft connecting rod, thereby driving the position of the downward pressure clearing piece to change, and then adapting to the depth of the feed port of different devices.

[0014] A further improvement of the technical solution of the utility model is that: a discharge port is provided below the impact wheel, the discharge port is in a rectangular shape, and a recovery box is provided below one side of the discharge port, a cross partition is provided on the other side of the discharge port, the other end of the cross partition is connected to the second connecting sleeve, the discharge port is slidably connected to the cross partition, and the other end of the cross partition is fixedly connected to the second connecting sleeve. In the above, during the rotation of the second connecting sleeve, if the direction is clockwise, because the cross partition is fixedly connected to the second connecting sleeve, the cross partition rotates clockwise, and because the cross partition is slidably connected to the discharge port, the cross partition gradually slides out of the discharge port and is placed when the second connecting sleeve rotates counterclockwise. At this time, the downward pressure clearing piece moves upward, and the cross partition slides toward the discharge port, pushing the crushed mechanical residue accumulated at the discharge port into the recovery box.

The recycling crushing and screening unit can avoid the blockage of the mechanical residual materials in the screening and sorting holes of the filter screen, and make the screening and sorting net perform corresponding cyclic vibration, thereby improving the screening and sorting efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4, the utility model provides a technical solution:

[0024] Embodiment 1

[0025] A waste material recovery, crushing and screening unit for mechanical processing comprises a recovery, crushing box 1 and a support leg 2, wherein the recovery, crushing box 1 and the support leg 2 are fixedly connected, a recovery chamber is provided in the recovery, crushing and screening unit is provided in the recovery chamber, a feeding unit is provided on the top of the recovery, crushing box 1, the feeding unit is located above a feed port 3, and the feed port 3 is fixedly installed on the top of the recovery, crushing box 1, the feeding unit comprises an extension plate 401, an articulated rod 1 402 and an articulated rod 2 403 are provided on the extension plate 401, a connecting sleeve 1 404 and a connecting sleeve 2 405 are provided on the articulated rod 1 402 and the articulated rod 2 403 respectively, a crankshaft connecting rod 406 is provided on the outer wall of the connecting sleeve 1 404 and the connecting sleeve 2 405, an adjusting screw 407 is provided on the crankshaft connecting rod 406, and a downward pressure dredging piece 408 is provided at the bottom of the adjusting screw 407.

[0026] The extension plate 401 is vertically fixedly installed on the top of the recycling crushing box 1, and the extension plate 401 is rotatably connected with the hinge rod 1 402 and the hinge rod 2 403. The connecting sleeve 1 404 and the connecting sleeve 2 405 are respectively sleeved on the hinge rod 1 402 and the hinge rod 2 403, and the two crankshaft connecting rods 406 are respectively fixedly connected with the connecting sleeve 1 404 and the connecting sleeve 2 405. Among them, after the hinge rod 1 402 or the hinge rod 2 403 rotates, the sleeve thereon rotates, and the crankshaft connecting rod 406 to which the sleeve is fixedly connected rotates, and then the adjusting screw 407 rotates, and then the vertical lifting and lowering occurs. At this time, due to the connection effect of the adjusting screw 407, the other rotating shaft and the sleeve rotate, and then the downward pressing dredging member 408 at the bottom of the adjusting screw 407 hits the mechanical residual material of the feed port 3, and then ensures the dredging of the feed port 3.

[0027] The adjusting screw 407 is vertically mounted on the crankshaft connecting rod 406, the adjusting screw 407 is threadedly connected to the crankshaft connecting rod 406, the adjusting screw 407 is fixedly connected to the downward pressure dredging piece 408, and the adjusting screw 407 is located directly above the feed port 3. Among them, the depths of the feed port 3 and the recovery chamber are different in different crushers and different devices. After the hinge rod 1 402 and the hinge rod 2 403 rotate, it is impossible to ensure that the adjusting screw 407 can be lowered to the bottom of the feed port 3 due to the limitation of the length of the crankshaft connecting rod 406. Then, when encountering this situation, the adjusting screw 407 can be rotated to make the adjusting screw 407 rise and fall on the crankshaft connecting rod 406, thereby driving the position of the downward pressure dredging piece 408 to change, and then adapting to the depth of the feed port 3 of different devices.

[0029] Among them, in the above, during the rotation of the connecting sleeve 2 405, if the direction is clockwise, because the diaphragm 411 is fixedly connected to the connecting sleeve 2 405, the diaphragm 411 rotates clockwise, and because the diaphragm 411 is slidingly connected to the discharge port 409, the diaphragm 411 gradually slides out of the discharge port 409, and is placed when the connecting sleeve 2 405 rotates counterclockwise. At this time, the downward pressure clearing piece 408 moves upward, and the diaphragm 411 slides toward the discharge port 409, pushing the crushed mechanical residue accumulated at the discharge port 409 into the recovery box 410.

[0030] When hinged rod 1 402 or hinged rod 2 403 rotates, the sleeve thereon rotates, and the crankshaft connecting rod 406 to which the sleeve is fixedly connected rotates, and then the adjusting screw 407 rotates, and then the vertical lifting and lowering occurs. At this time, due to the connecting action of the adjusting screw 407, the other rotating shaft and the sleeve rotate, and then the downward pressure clearing piece 408 at the bottom of the adjusting screw 407 impacts the mechanical residual material at the feed port 3, thereby ensuring the clearing of the feed port 3.
