Description

Technical Field

[0001] The utility model relates to the field of crushing equipment, in particular to a splash-proof device for a crusher feed inlet. Background Art

[0002] In the process of waste recycling, shredders are needed to carry out preliminary processing of the waste. The main function of the shredder is to crush, shear or tear large pieces of solid materials, waste materials or difficult-to-handle materials into smaller ones, so as to facilitate long-distance and large-scale transportation of the waste and facilitate recycling.

[0003] At present, shredders include single-axis random, double-axis shredders, four-axis shredders, etc. For example, a double-axis shredder disclosed in a Chinese patent with publication number CN106076548B includes a box and a cutter; a crushing chamber is formed inside the box, and both ends of the crushing chamber are provided with a mounting plate and a partition set at intervals, and a first gap is formed between the mounting plate and the partition; the cutter includes two knife shafts, a cutting knife body and a plurality of scraping knife bodies, and the two ends of each knife shaft pass through the partition respectively and are pivotally connected to the mounting plate with bearings; a plurality of the cutting knife bodies are fixed on each knife shaft; a second gap is formed between two adjacent cutting knife bodies on each knife shaft; the cutting knife body includes a cutting knife seat and a cutting blade; a plurality of cutting blades are distributed on the knife shaft in a spiral line; the scraping knife body includes a scraping knife seat and a scraping blade, and each scraping blade is arranged in each second gap one by one. The shredder provided by the above patent has strong cutting force; the scraping blade can be used to scrape off the residual material on the knife shaft, and the knife shaft runs more smoothly. At the same time, it is prevented that the material enters the bearing and causes damage to the bearing.

[0004] Whether it is a single-axis random shredder, a double-axis shredder, or a four-axis shredder, the top is set to be open so that waste materials can be put into the shredder to complete the shredding of waste materials. However, there are some problems with the shredder during operation. For example, when using the shredder to break hard objects, it is very likely that some fragments will fly out of the shredder when the object breaks. Since the delivery of waste materials generally requires staff to operate, the flying fragments are very likely to injure the staff; if some structures that can prevent the flying of fragments can be installed on the shredder, the probability of casualties will be reduced.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0025] Example 1

[0026] like Figure 1 , Figure 2As shown, the existing shredder mainly includes a bracket 1, a transmission mechanism, a chassis assembly, a crushing knife group 14, etc. The chassis assembly is arranged on the bracket 1, and the transmission mechanism is arranged on the frame. It includes a first motor 11, a pulley, a V-belt, a reducer, a coupling, etc. These components jointly transmit the power of the first motor 11 to the main shaft of the crushing knife group to ensure the normal operation of the shredder. The crushing knife group 14 is distributed in two axes, each including a main shaft, a coupling and a cutter disc. The cutter disc is fixedly arranged on the main shaft, and the main shaft is connected to the output shaft of the first motor 11 through a coupling. When the device is used to crush waste, the waste is put into the chassis from the upper end of the chassis, and the crushing knife group is controlled to rotate by the operation of the first motor 11, so that the crushing knife group can realize the crushing of waste. However, when the device is used to crush hard objects, some of the waste is very likely to fly out from the upper end of the shredder during crushing, and the flying fragments are likely to cause injuries to the staff.

[0027] In order to solve the above-mentioned problem, a partial structure is added to the existing shredder, which blocks the flying of fragments and reduces the probability of personal injury caused by the flying of fragments.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, specifically, a material box 12 is arranged above the bracket 1, and the material box 12 is located directly above the crushing knife group 14. Perforations 13 are arranged on the two opposite side walls of the material box 12. The perforations 13 are arranged in the middle and upper part of the material box 12, and the length is less than or equal to the length of the material box 12. Blocking plates 2 are arranged through the perforations 13, and an adjustment mechanism 4 is arranged below the two blocking plates 2. The adjustment mechanism 4 can control the relative movement of the two blocking plates 2. Under the operation of the adjustment mechanism 4, the two blocking plates 2 can be controlled to move relative to each other. This arrangement can make the two blocking plates 2 move away from each other before the waste materials are put in, so that the waste materials can be put into the material box 12 and contact the crushing knife group 14. After the waste materials are put in, the two blocking plates 2 are controlled by the adjustment mechanism 4 to move closer to each other to block the channel for the debris to fly.

[0029] like Figure 5 , Figure 6As shown, in order to control the movement of the two blocking plates 2 through the adjusting mechanism 4, the adjusting mechanism 4 includes a second motor 44 and two rotating shafts 42. The two rotating shafts 42 are arranged in parallel on the outside of the material box 12 and are fixedly connected to the material box 12 through a support plate. The ends of the two rotating shafts 42 are connected through a first transmission belt 41. At the same time, the end of one of the rotating shafts 42 is connected to the output shaft of the second motor 44 through a second transmission belt 43. The first transmission belt 41 and the second transmission belt 43 are both arranged on the side of the material box 12. Then, under the action of the second motor 44, the two rotating shafts 42 can rotate synchronously. A connecting plate 45 is provided on the side where the two rotating shafts 42 are away from each other. The connecting plate 45 is inclined relative to the rotating shaft 42, and a connecting frame 46 is hinged at the end. A driving column 47 is provided at the end of the connecting frame 46. The driving column 47 is provided with a threaded hole. A threaded structure 48 is provided on the rotating shaft 42, and the thread penetrates the driving column 47. When the second motor 44 works to force the driving column 47 to move, it also drives the connecting frame 46 to move, thereby forcing the end of the connecting plate 45 to move, thereby changing the inclination angle of the connecting plate 45 relative to the rotating shaft 42, and providing support for controlling the movement of the blocking plate 2.

[0030] like Figure 4 , Figure 5 As shown, a support frame 21 is fixedly arranged below the blocking plate 2, and a bottom column 22 is fixedly arranged below the support frame 21. The bottom column 22 is inserted into the other end of the connecting plate 45 away from the connecting frame 46, so as to realize the hinge connection between the connecting plate 45 and the blocking plate 2. When the inclination angle of the connecting plate 45 relative to the rotating shaft 42 changes, the blocking plate 2 moves relative to the material box 12. The height of the through hole 13 is greater than the sum of the heights of the blocking plate 2 and the support frame 21.

[0031] The structure added on the shredder is further improved and can also be used for other crushing equipment, and certainly needs to be changed according to the actual situation of the crushing equipment. In addition, the motor in this embodiment is connected to the controller of the crushing equipment.

[0032] Example 2

[0033] like Figure 1 , Figure 2As shown, the existing shredder mainly includes a bracket 1, a transmission mechanism, a chassis assembly, a crushing knife group 14, etc. The chassis assembly is arranged on the bracket 1, and the transmission mechanism is arranged on the frame. It includes a first motor 11, a pulley, a V-belt, a reducer, a coupling, etc. These components jointly transmit the power of the first motor 11 to the main shaft of the crushing knife group to ensure the normal operation of the shredder. The crushing knife group 14 is distributed in two axes, each including a main shaft, a coupling and a cutter disc. The cutter disc is fixedly arranged on the main shaft, and the main shaft is connected to the output shaft of the first motor 11 through a coupling. When the device is used to crush waste, the waste is put into the chassis from the upper end of the chassis, and the crushing knife group is controlled to rotate by the operation of the first motor 11, so that the crushing knife group can realize the crushing of waste. However, when the device is used to crush hard objects, some of the waste is very likely to fly out from the upper end of the shredder during crushing, and the flying fragments are likely to cause injuries to the staff.

[0034] In order to solve the above-mentioned problem, a partial structure is added to the existing shredder, which blocks the flying of fragments and reduces the probability of personal injury caused by the flying of fragments.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, specifically, a material box 12 is arranged above the bracket 1, and the material box 12 is located directly above the crushing knife group 14. Perforations 13 are arranged on the two opposite side walls of the material box 12. The perforations 13 are arranged in the middle and upper part of the material box 12, and the length is less than or equal to the length of the material box 12. Blocking plates 2 are arranged through the perforations 13, and an adjustment mechanism 4 is arranged below the two blocking plates 2. The adjustment mechanism 4 can control the relative movement of the two blocking plates 2. Under the operation of the adjustment mechanism 4, the two blocking plates 2 can be controlled to move relative to each other. This arrangement can make the two blocking plates 2 move away from each other before the waste materials are put in, so that the waste materials can be put into the material box 12 and contact the crushing knife group 14. After the waste materials are put in, the two blocking plates 2 are controlled by the adjustment mechanism 4 to move closer to each other to block the channel for the debris to fly.

[0036] like Figure 5 , Figure 6As shown, in order to control the movement of the two blocking plates 2 through the adjusting mechanism 4, the adjusting mechanism 4 includes a second motor 44 and two rotating shafts 42. The two rotating shafts 42 are arranged in parallel on the outside of the material box 12 and are fixedly connected to the material box 12 through a support plate. The ends of the two rotating shafts 42 are connected through a first transmission belt 41. At the same time, the end of one of the rotating shafts 42 is connected to the output shaft of the second motor 44 through a second transmission belt 43. The first transmission belt 41 and the second transmission belt 43 are both arranged on the side of the material box 12. Then, under the action of the second motor 44, the two rotating shafts 42 can rotate synchronously. A connecting plate 45 is provided on the side where the two rotating shafts 42 are away from each other. The connecting plate 45 is inclined relative to the rotating shaft 42, and a connecting frame 46 is hinged at the end. A driving column 47 is provided at the end of the connecting frame 46. The driving column 47 is provided with a threaded hole. A threaded structure 48 is provided on the rotating shaft 42, and the thread penetrates the driving column 47. When the second motor 44 works to force the driving column 47 to move, it also drives the connecting frame 46 to move, thereby forcing the end of the connecting plate 45 to move, thereby changing the inclination angle of the connecting plate 45 relative to the rotating shaft 42, and providing support for controlling the movement of the blocking plate 2.

[0037] like Figure 4 , Figure 5 As shown, a support frame 21 is fixedly arranged below the blocking plate 2, and a bottom column 22 is fixedly arranged below the support frame 21. The bottom column 22 is inserted into the other end of the connecting plate 45 away from the connecting frame 46, so as to realize the hinge connection between the connecting plate 45 and the blocking plate 2. When the inclination angle of the connecting plate 45 relative to the rotating shaft 42 changes, the blocking plate 2 moves relative to the material box 12. The height of the through hole 13 is greater than the sum of the heights of the blocking plate 2 and the support frame 21.

[0038] like Figure 3 As shown, in order to place the blocking plate 2 stably, a limiting plate 3 is provided above the two blocking plates 2 on one side away from each other. The two limiting plates 3 are both fitted on the outside of the material box 12, and the bottom surface of the limiting plate 3 is in sliding contact with the upper side surface of the blocking plate 2. Under the action of the limiting plate 3, the blocking plate 2 is forced to be stably placed using the lever principle.

[0039] The structure added on the shredder is further improved and can also be used for other crushing equipment, and certainly needs to be changed according to the actual situation of the crushing equipment. In addition, the motor in this embodiment is connected to the controller of the crushing equipment.
