Description

Technical Field

[0001] The invention belongs to the technical field of feed processing, and in particular relates to a crushing device for feed processing. Background Art

[0002] Feed processing and grinding is an indispensable part of the feed production process. It involves subjecting the feed raw materials to a series of processing techniques, such as crushing and refining, so that their particle size reaches the standard suitable for animal digestion and absorption. The main purpose of feed grinding is to change the physical form of the raw materials from large particles (blocks) to small particles or powder, so that animals can swallow and digest them more easily, thereby improving the digestibility and utilization of the feed. In the process of feed processing and grinding, the main grinding device is used to grind it.

[0003] Conventional pulverizing devices mainly use pulverizing rollers to achieve the pulverizing process of feed, that is, the shear force generated by the relative rotation between two pulverizing rollers is generally used to achieve the pulverizing process of feed. When in use, the feed to be pulverized is generally put into the space between the two pulverizing rollers through the feed inlet for pulverization. However, in this pulverizing device, the feed is mainly concentrated in the middle of the two pulverizing rollers during pulverization, resulting in different wear depths at different locations of the pulverizing rollers, which seriously affects the service life of the pulverizing rollers.

[0004] At the same time, when the feed is crushed, since some feed particles are large, after a long period of use, some feed will be stuck between the two crushing rollers. At this time, the device must be shut down and cleaned with external tools. If necessary, the crushing rollers must be disassembled for maintenance and cleaning. The overall maintenance difficulty is high and the maintenance efficiency is low. Summary of the invention

[0005] The object of the present invention is to provide a pulverizing device for feed processing to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a feed processing crushing device comprises a primary crushing box, the bottom end of the primary crushing box is fixedly connected with a channel box, the bottom end of the channel box is fixedly connected with a secondary crushing box, a base is fixedly installed at the front and rear sides of the bottom end of the secondary crushing box, equipment boxes are fixedly installed on the left and right sides near the top of the secondary crushing box, annular grooves are symmetrically provided on the left and right sides of the middle part of the secondary crushing box and at positions near the front and rear ends, main shafts are movably installed on the left and right sides inside the primary crushing box, a discharge port is provided in the middle part of the bottom end of the secondary crushing box, a buffer plate is fixedly installed at the bottom end of the base, the outer sides of the two main shafts are fixedly sleeved with crushing knives located inside the primary crushing box, and the left and right sides of the top of the secondary crushing box are fixedly sleeved with crushing knives located inside the primary crushing box. Main power components are installed on both sides of the right side, and the other end of the main power component is fixedly sleeved with the main shaft, and rolling rollers are movably installed on the front and rear sides of the inner cavity of the secondary crushing box, and power transmission components are movably installed inside the equipment box, and the top of the power transmission component is fixedly connected to the main shaft, and the other end of the power transmission component is connected to two rolling rollers, and the rolling roller is movably connected between the power shaft and the annular groove, and adjustment components are installed on both sides of the left and right sides of the secondary crushing box, and one end of the adjustment component is movably sleeved with the power shaft of the rolling roller, and a four-way valve is provided directly above the primary crushing box, and the top of the four-way valve is connected to the external water pump, and the left and right ends of the four-way valve are fixedly connected with infusion pipes, and the other end of the infusion pipe is connected to the adjustment component.

[0007] Before use, it is necessary to ensure that the top of the four-way valve is connected to the external water pump. At the same time, in the initial state, the bottom of the four-way valve and the valves on the left and right ends are in a closed state, and a receiving box must be placed at the bottom of the discharge port to receive the processed feed.

[0008] As a further technical solution of the present invention, the main power component includes a main motor, the top of the main motor is connected to the top of the secondary crushing box through a fixing part, the output shaft of the main motor is fixedly sleeved with a first transmission shaft, the outer side of the first transmission shaft is movably sleeved with a synchronous belt, and the end of the synchronous belt away from the first transmission shaft is movably sleeved with a second transmission shaft.

[0009] As a further technical solution of the present invention, the second transmission shaft is fixedly sleeved with the outer side surface of the main shaft, and the first transmission shaft is transmission-connected with the second transmission shaft via a synchronous belt.

[0010] When crushing the feed, the feed to be crushed can be put into the first-level crushing box and the main motor can be turned on. At this time, the main motor can drive the first transmission shaft to rotate, and drive the second transmission shaft to rotate through the synchronous belt on the outer side of the first transmission shaft. At this time, the main shaft located on the inner side of the second transmission shaft rotates accordingly to complete the power transmission process. At the same time, the rotation directions of the left and right main motors are completely opposite. At this time, the rotation directions of the two main shafts are also completely opposite, until the two crushing knives are driven to rotate relative to each other, and the feed located inside the first-level crushing box is initially crushed. The feed that has been initially crushed can be introduced into the second-level crushing box through the channel box.

[0011] As a further technical solution of the present invention, the power transmission component includes a first bevel gear, the top of the first bevel gear is connected to the main shaft, the first bevel gear is movably connected to the equipment box, the bottom of the first bevel gear is vertically meshed with a second bevel gear, the second bevel gear is movably connected to the equipment box, and the power transmission component also includes a driving gear located on the outer side of the equipment box, and the middle part of the driving gear is connected to the second bevel gear.

[0012] As a further technical solution of the present invention, the power transmission component also includes a diagonally arranged driven gear, and the two driven gears are diagonally fixedly sleeved between the power shafts in the middle of the two rolling rollers. The power transmission component also includes a diagonally arranged counterweight wheel, and the two counterweight wheels are arranged parallel to the rolling rollers and diagonally installed on the power shafts of the two rolling rollers, and the driven gear is meshedly connected with the driving gear.

[0013] At the same time, when the main shaft rotates, it can drive the two first bevel gears to rotate. At this time, the second bevel gear meshing with it below can rotate after completing the reversal, and drive the two driving gears to rotate. Since the rotation directions of the two main shafts are opposite, the rotation directions of the two driving gears are also opposite. At the same time, the two driving gears can drive the two driven gears meshing with them to rotate. Since the two rolling rollers are connected to the driven gears, the two rolling rollers can eventually be driven to rotate relative to each other, and the feed located inside the secondary crushing box is crushed for the second time. The crushed feed can be discharged through the discharge port to complete the feed crushing process.

[0014] By utilizing the rotation process of the main shaft during the initial crushing and the cooperation between the power transmission component and the main shaft, the device can complete the secondary crushing of the feed simultaneously while completing the initial crushing of the feed, without the need to set up an additional power device. The initial crushing and the secondary crushing can be started and stopped at the same time, which effectively improves the crushing efficiency of the feed and reduces energy consumption.

[0015] As a further technical solution of the present invention, a material baffle plate is movably connected to the middle part of the channel box, and the material baffle plate is displaced left and right relative to the channel box. The outer side surfaces of the two main shafts near the bottom ends are fixedly sleeved with cams, and the two cams are arranged in parallel and correspond end to end. The left and right ends of the material baffle plate are respectively in contact with the tail of the left cam and the head of the right cam.

[0016] At the same time, the feed that has been initially crushed can be blocked by the baffle plate inside the channel box when it enters the channel box and is introduced into the secondary crushing box. When the two main shafts rotate, the two cams can be driven to rotate synchronously. At this time, the two cams can be driven to move back and forth left and right in cooperation with the clamping action between the baffle plate and the channel box. At this time, the feed entering the channel box can be intermittently blocked, so that the feed is evenly distributed at the left and right ends of the channel box, that is, it is finally evenly distributed between the two rolling rollers to complete automatic uniform feeding.

[0017] By utilizing the power of the device during initial crushing, as well as the cooperation between the baffle plate, the cam and the main shaft, the device can block the movement trajectory of the feed through intermittent blocking during initial crushing, so that it is evenly distributed to the position between the two rolling rollers. The whole process is completed automatically, avoiding the problem of excessive wear caused by the feed being concentrated in the middle of the rolling roller of the transmission device, improving the wear uniformity and increasing its service life.

[0018] As a further technical solution of the present invention, the adjustment component includes an adjustment tube, which is connected to one side of the secondary crushing box, and the top of the adjustment tube away from the secondary crushing box is fixedly connected to an infusion port, the top of the infusion port is connected to the infusion tube, and the inside of the adjustment tube is movably sleeved with an adjustment plate, and the side of the adjustment plate away from the primary crushing box is fixedly connected to an adjustment rod located inside the adjustment tube.

[0019] As a further technical solution of the present invention, the outer side surface of the adjusting rod is movably sleeved with a limit spring, the left and right ends of the limit spring are respectively connected to one side of the adjusting tube and one side of the adjusting plate, and the side of the adjusting rod away from the secondary crushing box passes through one side of the adjusting tube and is fixedly connected to an adjusting seat.

[0020] As a further technical solution of the present invention, the front and rear ends of the adjustment seat close to the secondary crushing box are fixedly connected to the second fixed seat, the end of the second fixed seat away from the adjustment seat is movably connected to the connecting rod through a rotating shaft, the end of the connecting rod away from the second fixed seat is movably connected to the first fixed seat through a rotating shaft, the end of the first fixed seat away from the connecting rod is fixedly connected to a locking piece, and the middle part of the locking piece is fixedly sleeved with the power shaft of the rolling roller.

[0021] As a further technical solution of the present invention, when the limit spring is in an initial state, the distance between the adjustment seat and the adjustment tube is a maximum value, and the distance between the two locking members is a minimum value.

[0022] And during the secondary crushing process, if the feed is stuck between the two rolling rollers, the external water pump can be directly turned on. At this time, the water pump can output high-pressure water to the inside of the four-way valve, and at the same time, it is exported through the bottom end of the four-way valve to act on the inside of the primary crushing box, and finally acts between the two rolling rollers to complete the preliminary cleaning. At the same time, the high-pressure water can be exported through the two infusion tubes and enter the inside of the two adjusting components. At this time, the high-pressure water can exert a force on the adjusting plate, and the limit spring is compressed, and the adjusting seat approaches the direction of the adjusting tube. The two connecting rods deflect in the direction away from each other, and at the same time, a thrust is applied to the two locking parts. At this time, the two locking parts are relatively separated, and under the action of the two adjusting components, through the cooperation between the rolling roller and the annular groove, the two rolling rollers are guided by the annular groove and move away from each other. At this time, the distance between the two rolling rollers increases, and the debris stuck in the middle falls off, completing the self-maintenance process.

[0023] By utilizing external high-pressure water and the interaction between the rolling rollers and the adjustment components, the device can automatically separate the two rolling rollers without shutting down. There is no need to disassemble the two rolling rollers. The entire process can be completed online, effectively avoiding the traditional complicated disassembly and maintenance process, simplifying the maintenance steps, reducing the difficulty of maintenance, and improving the overall maintenance efficiency.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention utilizes the power of the device during preliminary crushing, as well as the cooperation between the baffle plate, the cam and the main shaft, so that when the device is performing preliminary crushing, it can also block the movement trajectory of the feed through intermittent blocking, so that it is evenly distributed to the position between the two rolling rollers. The whole process is completed automatically, avoiding the problem of excessive wear caused by the feed of the transmission device being concentrated in the middle of the rolling roller, improving the wear uniformity, and increasing its service life.

[0026] 2. The present invention utilizes external high-pressure water and the interaction between the rolling rollers and the adjustment components, so that the device can automatically separate the two rolling rollers without stopping, and there is no need to disassemble the two rolling rollers. The entire process can be completed online, effectively avoiding the traditional complicated disassembly and maintenance process, simplifying the maintenance steps, reducing the difficulty of maintenance, and improving the overall maintenance efficiency.

[0027] 3. The present invention utilizes the rotation process of the main shaft during the initial crushing, and the cooperation between the power transmission component and the main shaft, so that the device can complete the secondary crushing of the feed simultaneously while completing the initial crushing of the feed, without the need to set up an additional power device. The initial crushing and the secondary crushing can be started and stopped at the same time, which effectively improves the crushing efficiency of the feed and reduces energy consumption.

The left and right ends of the four-way valve 16 are fixedly connected with an infusion tube 17, and the other end of the infusion tube 17 is connected to the adjustment component 18.

[0040] Before use, it is necessary to ensure that the top of the four-way valve 16 is connected to the external water pump. At the same time, in the initial state, the bottom end of the four-way valve 16 and the valves on the left and right ends are in a closed state, and a receiving box must be placed at the bottom end of the discharge port 5 for receiving the processed feed.

[0041] like Figure 1 and Figure 2 as well as Figure 3As shown, the main power component 8 includes a main motor 801, the top of the main motor 801 is connected to the top of the secondary crushing box 2 through a fixing part, the output shaft of the main motor 801 is fixedly sleeved with a first transmission shaft 802, the outer side of the first transmission shaft 802 is movably sleeved with a synchronous belt 804, and the end of the synchronous belt 804 away from the first transmission shaft 802 is movably sleeved with a second transmission shaft 803, the second transmission shaft 803 is fixedly sleeved with the outer side of the main shaft 6, and the first transmission shaft 802 is transmission-connected to the second transmission shaft 803 through the synchronous belt 804.

[0042] When crushing the feed, the feed to be crushed can be put into the first-level crushing box 1, and the main motor 801 is turned on. At this time, the main motor 801 can drive the first transmission shaft 802 to rotate, and drive the second transmission shaft 803 to rotate through the synchronous belt 804 on the outer side of the first transmission shaft 802. At this time, the main shaft 6 located on the inner side of the second transmission shaft 803 rotates accordingly to complete the power transmission process. At the same time, the rotation directions of the left and right main motors 801 are completely opposite.

The feed that has completed the initial crushing can be introduced into the interior of the secondary crushing box 2 through the channel box 9.

[0043] like Figure 1 and Figure 5 as well as Figure 6 and Fig. 9 As shown, the power transmission component 15 includes a first bevel gear 151, the top of the first bevel gear 151 is connected to the main shaft 6, the first bevel gear 151 is movably connected to the equipment box 12, and the second bevel gear 152 is vertically meshed and connected below the first bevel gear 151, and the second bevel gear 152 is movably connected to the equipment box 12. The power transmission component 15 also includes a driving gear 153 located on the outer side of the equipment box 12, and the middle part of the driving gear 153 is connected to the second bevel gear 152. The power transmission component 15 also includes a diagonally arranged driven gear 154, and the two driven gears 154 are diagonally fixedly sleeved with the power shafts in the middle parts of the two rolling rollers 14 respectively.

The entire process can be completed online, effectively avoiding the traditional complicated disassembly and maintenance process, simplifying the maintenance steps, reducing the difficulty of maintenance, and improving the overall maintenance efficiency.

[0052] Working principle and usage process:

[0053] When the feed is crushed, the feed to be crushed can be put into the first-level crushing box 1, and the main motor 801 is turned on. At this time, the main motor 801 can drive the first transmission shaft 802 to rotate, and drive the second transmission shaft 803 to rotate through the synchronous belt 804 on the outer side of the first transmission shaft 802. At this time, the main shaft 6 located on the inner side of the second transmission shaft 803 rotates accordingly to complete the power transmission process. At the same time, the rotation directions of the left and right main motors 801 are completely opposite. At this time, the rotation directions of the two main shafts 6 are also completely opposite, until the two crushing knives 7 are driven to rotate relative to each other, and the feed located inside the first-level crushing box 1 is initially crushed. The feed that has been initially crushed can be introduced into the interior of the secondary crushing box 2 through the channel box 9;

[0054] At the same time, when the main shaft 6 rotates, the two first bevel gears 151 can be driven to rotate. At this time, the second bevel gear 152 meshing therewith can rotate after the reversal is completed, and drive the two driving gears 153 to rotate. Since the rotation directions of the two main shafts 6 are opposite, the rotation directions of the two driving gears 153 are also opposite. At the same time, the two driving gears 153 can drive the two driven gears 154 meshing therewith to rotate. Since the two rolling rollers 14 are both connected to the driven gears 154, the two rolling rollers 14 can be driven to rotate relative to each other, and the feed located inside the secondary crushing box 2 is crushed for the second time. The crushed feed can be discharged through the discharge port 5 to complete the feed crushing process;

[0055] At the same time, the feed that has been initially crushed can be blocked by the baffle plate 10 inside the channel box 9 when it enters the channel box 9 and is introduced into the secondary crushing box 2. When the two main shafts 6 rotate, the two cams 11 can be driven to rotate synchronously. At this time, the baffle plate 10 can be driven to move back and forth left and right under the drive of the two cams 11 and in cooperation with the clamping effect between the baffle plate 10 and the channel box 9. At this time, the feed entering the channel box 9 can be intermittently blocked, so that the feed is evenly arranged at the left and right ends of the channel box 9, that is, finally evenly arranged between the two rolling rollers 14, completing automatic uniform feeding;

[0056] And during the secondary crushing process, if the feed is stuck between the two rolling rollers 14, the external water pump can be directly turned on. At this time, the water pump can output high-pressure water to the inside of the four-way valve 16, and at the same time, it is exported through the bottom end of the four-way valve 16 to act on the inside of the primary crushing box 1, and finally acts between the two rolling rollers 14 to complete the preliminary cleaning. At the same time, the high-pressure water can be exported through the two infusion pipes 17 and enter the inside of the two adjustment components 18. At this time, the high-pressure water can apply a force to the adjustment plate 182, and at the same time, the limit spring 187 is compressed, and the adjustment seat 188 approaches the direction of the adjustment tube 181. The two connecting rods 1810 deflect in the direction away from each other, and at the same time, a thrust is applied to the two locking members 184. At this time, the two locking members 184 are relatively separated, and under the action of the two adjustment components 18, through the cooperation between the rolling roller 14 and the annular groove 13, the two rolling rollers 14 are guided by the annular groove 13 and move away from each other. At this time, the distance between the two rolling rollers 14 increases, and the debris stuck in the middle falls off, completing the self-maintenance process.
