Description

Technical Field

[0001] The utility model relates to the technical field of metal shredding mechanisms, in particular to a mobile metal full-hydraulic shredding mechanism. Background Art

[0002] With the shortage of steel resources, the country has vigorously developed the recycling of scrap steel. The existing treatment plan is to concentrate scrap steel in large-scale treatment plants for treatment. Scrap steel has different sizes and shapes, large transportation dimensions, and high freight. Mobile metal shredders can automatically feed and shear on site, so that scrap steel can be directly sent to steel mills after on-site processing. However, most of the existing mobile metal shredders are driven by motors, which will cause the cylinder to overheat during long-term use, which will greatly reduce the service life of the hydraulic cylinder. Therefore, we designed a mobile metal fully hydraulic shredding mechanism.

The distance becomes larger, so that the metal waste will fall onto the conveyor belt at the bottom, and then the static row knife seat is moved to the original position. In this way, the metal waste can be taken out by changing the distance between the static row knife seat and the ruler-type tool without shutting down the machine, thereby increasing the shredding efficiency of the metal waste and solving the problems raised in the above background. However, the utility model has the following problems: first, it does not have the effect of increasing the heat dissipation of the cylinder to avoid overheating of the cylinder and greatly reduce the service life of the hydraulic cylinder. Secondly, the use of motor drive is heavy, large in size, easy to wear, and has high maintenance costs. Utility Model Content

[0026] like Figures 1 to 5 As shown, the utility model provides a mobile metal full hydraulic shredding mechanism, including a support frame 1, which increases the ground height of the power chamber of the metal full hydraulic shredding mechanism. A protective frame is provided at the edge of the support frame 1 to prevent the hydraulic oil tank 2, the diesel tank 4, the engine assembly 10 and other power components from colliding with external objects. A hydraulic oil tank 2 is provided at the left front corner of the upper end of the support frame 1 to store hydraulic oil and provide an installation position for a cooler 9. A mounting frame 3 is provided on the right side of the hydraulic oil tank 2 to form a multi-layer installation position, increase the installation space, thereby reducing the overall volume and increasing the space utilization rate. A diesel tank 4 is provided on the right side of the mounting frame 3 to store the oil required for the pump to work. The diesel tank 4 and the bottom of the hydraulic oil tank 2 are both provided with a heat dissipation structure 5, which is cooled from the bottom. The diesel tank 4 and the hydraulic oil tank 2 are cooled. The heat dissipation structure 5 includes a condenser tank 51 for storing condensate. A ventilation box 52 is provided at the lower end of the condenser tank 51. The heat transferred from the condenser tank 51 is cooled here. Heat dissipation grooves are evenly distributed on the surface of the ventilation box 52. Heat is exchanged through the heat dissipation grooves. A booster pump 515 is provided at the front end of the condenser tank 51. The condensate in the condenser tank 51 is transported to the condenser pipe 54 by pressurization. The booster pump 515 is controlled by the electric control box 11. A No. 1 connecting pipe 53 is provided between the booster pump 515 and the condenser tank 51. The condensate in the condenser tank 51 enters the condenser pipe 54 through the No. 1 connecting pipe 53 and the No. 2 connecting pipe 56 under the action of the booster pump 515.

[0027] Further, if Figure 5 As shown, a condenser 54 is provided at the right end inside the hydraulic oil tank 2 and the rear end inside the diesel tank 4 to cool down the temperature inside the hydraulic oil tank 2 and the diesel tank 4, and a heating pipe 55 is provided at the left end inside the hydraulic oil tank 2 and the front end inside the diesel tank 4 to heat up the temperature inside the hydraulic oil tank 2 and the diesel tank 4. A second connecting pipe 56 is provided between the condenser 54 and the boost pump 515. The end of the heating pipe 55 away from the hydraulic oil tank 2 or the diesel tank 4 is connected to a heating device 6, which is controlled by the electronic control box 11. The heating device 6 works, so that the heating pipe 55 works to heat the oil.

[0028] Further, if Figure 4As shown, the exchange grooves 57 are evenly distributed at the lower end of the condensing box 51, providing installation space for the sealing ring 58 and the exchange plate 59.

The inner surface of the sealing ring 58 is provided with an exchange plate 59, and the lower end of the exchange plate 59 is located inside the ventilation box 52. The exchange plate 59 is a thin plate made of heat-conducting metal, and its upper end absorbs the heat in the condensing box 51 and transfers it to the ventilation box 52. The heat is quickly dissipated under the action of air cooling, thereby improving the heat exchange rate, and enabling the grease inside the condensing box 51 to always maintain a relatively low temperature.

[0029] Furthermore, fans 510 are symmetrically provided at the lower side of the exchange plate 59. The fans 510 rotate to form wind flow, which blows directly to the exchange plate 59 to accelerate the heat dissipation from the heat dissipation holes and accelerate the heat dissipation. The lower end of the fan 510 passes through the surface of the ventilation box 52 to connect to the pulley 511. A transmission belt 512 is provided between the pulleys 511. A bevel gear 513 is provided at the lower end of the left fan 510. The outer surface of the bevel gear 513 is connected to a transmission structure 514. The transmission structure 514 includes a bevel gear and a motor.

[0030] Further, if Figure 1 As shown, the upper ends of the diesel tank 4 and the hydraulic oil tank 2 are both provided with a temperature sensor 7, which monitors the temperature inside the diesel tank 4 or the hydraulic oil tank 2, and feeds back the detected temperature to the electronic control box 11. The electronic control box 11 makes a judgment based on the fed-back temperature value, and further controls the heating device 6 or the booster pump 515 to work. If the temperature is lower than the preset value range, the heating device 6 works, so that the heating pipe 55 heats the grease to avoid condensation under low temperature conditions and ensure normal use; if the temperature is higher than the preset value range, the booster pump 515 works, so that the condensate in the condensation tank 51 enters the condensation pipe 54, so that the grease is cooled, and the oil cylinder is prevented from overheating and the service life of the hydraulic oil tank 2 is greatly reduced. In addition, the front ends of the diesel tank 4 and the hydraulic oil tank 2 are both provided with a liquid level meter 8, so that people can check the oil amount inside the diesel tank 4 and the hydraulic oil tank 2 from the outside.

[0031] Further, if Figure 5As shown, a filter 21 is provided on the left side of the upper end of the hydraulic oil tank 2, and new grease is added and filtered from the filter 21 to ensure the purity of the grease. A cooler 9 is provided in the middle of the upper end of the hydraulic oil tank 2 to perform air cooling on the engine assembly 10, and the rear end of the hydraulic oil tank 2 is provided with an engine assembly 10, including components such as a liquid storage device, a pump, a motor, and a control valve, which are the main power components. A manifold block 31 is provided on the bottom surface of the mounting frame 3, and an air filter 32 is provided on the upper end of the mounting frame 3 to perform secondary filtering on the grease flowing out of the hydraulic oil tank 2 to prevent the grease from being deposited and condensed in the oil pipe, causing the oil pipe to be blocked, and also to improve the service life of the engine assembly 10. A pre-filter device 33 is provided on the upper end of the air filter 32 to play a pre-filtering role.

[0032] Further, if Figure 2 As shown, an electric control box 11 is provided at the rear end of the engine assembly 10 for controlling the operation of the power chamber of the entire metal full-hydraulic shredding mechanism, and a closed pump 12 is provided on the right side of the engine assembly 10 to ensure the normal circulation of the condensate, save energy, and reduce production costs. A control valve group 13 is provided on the right side of the electric control box 11 to control the on-off circuit and flow rate of each oil pipe.

[0033] Working process: First, the engine assembly 10 works, and the diesel tank 4 and the hydraulic oil tank 2 provide grease for it. After long-term operation, the temperature sensor 7 monitors the temperature inside the diesel tank 4 or the hydraulic oil tank 2; further, if the temperature detected by the temperature sensor 7 is higher than the preset value range, the information is fed back to the electronic control box 11, and the electronic control box 11 further controls the boost pump 515 to work, so that the condensate in the condensation tank 51 enters the condensation pipe 54, so that the grease is cooled, and the oil cylinder is prevented from overheating and greatly reducing the service life of the hydraulic oil tank 2 and the diesel tank 4; further, the hydraulic oil tank 2 The temperature of the diesel tank 4 is absorbed by the condensate, so that the temperature of the condensate in the condensate box 51 increases, and the upper end of the exchange plate 59 absorbs the heat in the condensate box 51 and transfers it to the ventilation box 52; at the same time, the transmission structure 514 rotates under the control of the electronic control box 11, and transmits the rotational force to the bevel gear 513 through gear meshing, so that the left fan 510 rotates, and the power is transmitted to the right fan 510 through the transmission belt 512 and the pulley 511, so as to cool the exchange plate 59 with air, and the heat is dissipated from the heat dissipation groove on the surface of the ventilation box 52 into the external air.
