Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and particularly relates to a straw crushing device for agricultural machinery. Background Art

[0002] Straw crushing is an important way to process crop straws. It breaks the straws into small segments or particles for subsequent utilization or treatment, generally used for feeding livestock and returning to the field to improve soil fertility. Straw crushing requires the use of a straw crusher. However, the existing straw crushers generally only have a single set of crushing mechanisms, resulting in the situation that some straws are not crushed sufficiently. Summary of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a straw crushing device for agricultural machinery. By setting a group of motors to drive two synchronously running cutting mechanisms, the crushing effect is effectively improved.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A straw crushing device for agricultural machinery, including a bracket, a crushing bin is installed at the top of the bracket. Inside the crushing bin, a first crushing cutter roller and a second crushing cutter roller are rotatably installed. Two groups of rotating cutter shafts are also rotatably installed inside the crushing bin. Blades are installed on the outer sides of the rotating cutter shafts. A fixed frame is installed on the side of the crushing bin. A motor and a two-way transmission device are installed at the top of the fixed frame. One end of each of the first crushing cutter roller and the second crushing cutter roller is connected to a gear. The two gears mesh with each other. A gear speed increaser is installed at the bottom of the crushing bin. One end of the gear and the input shaft of the gear speed increaser are both connected to the two-way transmission device. Pulley wheels are installed at the bottom of the output shaft of the gear speed increaser and at the bottom of the rotating cutter shaft. A belt is connected between the pulley wheels. An output pipe is connected to the bottom of the crushing bin. A bag mouth clamping device is installed on the outer side of the output pipe.

[0005] The beneficial effect of the utility model is as follows: When the device is in use, a woven bag can be directly used to receive the crushed straws. Through the setting of the bag mouth clamping device, the bag mouth of the woven bag can be directly fixed without manual support. When fixing the woven bag, put the bag mouth on the outer side of the output pipe, then turn the knob. The rotation of the knob drives the two-way lead screw to rotate, thereby driving the slider and the clamping plate to move towards each other and get closer. The bag mouth of the woven bag is clamped and fixed through the cooperation between the clamping plate and the outer wall of the output pipe. Then tighten the locking nut sleeve to lock the two-way lead screw so that it cannot rotate.

[0006] The first rotating shaft is driven to rotate by a motor. The first rotating shaft directly drives the gear to rotate. Under the meshing transmission of two groups of gears, the first crushing cutter roller and the second crushing cutter roller rotate synchronously. At the same time, the first rotating shaft can drive the second rotating shaft to rotate through the transmission between the first bevel gear and the second bevel gear. By setting the gear speed increaser, the rotation speed can be amplified, and the rotation speed of the pulley at the bottom of the gear speed increaser can be increased. The pulley at the bottom of the gear speed increaser drives the pulley at the bottom of a group of rotary cutter shafts through a belt, and this group of rotary cutter shafts drives the pulley at the bottom of another group of rotary cutter shafts through a belt, so that both groups of rotary cutter shafts can rotate at high speed. The straw entering the crushing chamber is first preliminarily crushed by the first crushing cutter roller and the second crushing cutter roller, and then descends, and is further cut and crushed by the blades on two groups of high-speed rotating rotary cutter shafts. By setting a group of motors to drive two synchronously operating cutting mechanisms, the crushing effect is effectively improved.

[0007] In order for the motor to output power in two directions simultaneously:

[0008] As a further improvement of the above technical solution: The bidirectional transmission device includes a transmission box installed on a fixed frame. A first rotating shaft is penetrated and rotatably installed between two ends of the transmission box. A first bevel gear is sleeved on the outer side of the first rotating shaft. A second rotating shaft is penetrated and rotatably installed at the bottom of the transmission box. A second bevel gear is installed at the top of the second rotating shaft. The second bevel gear and the first bevel gear are meshed.

[0009] The beneficial effect of this improvement is that when the first rotating shaft rotates, in addition to driving the gear to rotate, it also drives the second rotating shaft to rotate through the meshing transmission between the second bevel gear and the first bevel gear, so as to output power in two directions simultaneously.

[0010] In order to drive the first crushing cutter roller and the second crushing cutter roller to rotate:

[0011] As a further improvement of the above technical solution: The output end of the motor is connected to one end of the first rotating shaft, and one end of the first rotating shaft is connected to one of the gears.

[0012] The beneficial effect of this improvement is that the motor directly drives the first rotating shaft to rotate, and drives the gear to rotate through the first rotating shaft, and further drives the first crushing cutter roller and the second crushing cutter roller to rotate.

[0013] In order to drive two groups of rotary cutter shafts to rotate:

[0014] As a further improvement of the above technical solution: The input shaft of the gear speed increaser is connected to the bottom end of the second rotating shaft.

[0015] The beneficial effects of this improvement are as follows: The second rotating shaft drives the gear speed increaser to rotate. Through the setting of the gear speed increaser, the rotational speed can be amplified. The operation of the gear speed increaser drives two groups of rotating cutter shafts to rotate through a belt.

[0016] In order to clamp and fix the bag mouth of the woven bag:

[0017] As a further improvement of the above technical solution: The bag mouth clamping device includes a fixture mounting plate. A slide rail is installed on the side of the fixture mounting plate. A bidirectional lead screw is rotatably installed inside the slide rail and a slider is slidably provided. The bidirectional lead screw and the slider are threadedly connected. The top of the bidirectional lead screw is connected with a knob, and a clamping plate is installed on the side of the slider.

[0018] The beneficial effects of this improvement are as follows: When this device is in use, a woven bag can be directly used to receive the crushed straw. Through the setting of the bag mouth clamping device, the bag mouth of the woven bag can be directly fixed, and there is no need for someone to hold the bag mouth. When fixing the woven bag, put the bag mouth on the outside of the output pipe, and then rotate the knob. The rotation of the knob drives the bidirectional lead screw to rotate, thereby driving the slider and the clamping plate to move towards each other and get closer, and clamping and fixing the bag mouth of the woven bag through the cooperation between the clamping plate and the outer wall of the output pipe.

[0019] In order to avoid loosening of the clamping:

[0020] As a further improvement of the above technical solution: A locking nut is threadedly installed on the outer side of the top of the bidirectional lead screw.

[0021] The beneficial effects of this improvement are as follows: After completing the clamping of the bag mouth of the woven bag, tighten the locking nut to lock the bidirectional lead screw so that it cannot rotate, thereby avoiding loosening of the clamping.

Specific embodiments

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0032] As Figures 1-7 shown, a straw crushing device for agricultural machinery includes a bracket 1. A crushing bin 2 is installed at the top of the bracket 1. A first crushing cutter roller 3 and a second crushing cutter roller 4 are rotatably installed inside the crushing bin 2. Two groups of rotating cutter shafts 5 are also rotatably installed inside the crushing bin 2. Blades 6 are installed on the outer side of the rotating cutter shafts 5. A fixed frame 7 is installed on the side of the crushing bin 2. A motor 8 and a bidirectional transmission device are installed on the top of the fixed frame 7. One end of each of the first crushing cutter roller 3 and the second crushing cutter roller 4 is connected to a gear 14. The two gears 14 mesh with each other. A gear speed increaser 15 is installed at the bottom of the crushing bin 2. One end of the gear 14 and the input shaft of the gear speed increaser 15 are both connected to the bidirectional transmission device. A pulley 16 is installed at the bottom of the output shaft of the gear speed increaser 15 and at the bottom of the rotating cutter shaft 5. The pulleys 16 are connected by a belt 17. The bottom of the crushing bin 2 is connected to an output pipe 18. A bag mouth clamping device is installed on the outer side of the output pipe 18.

[0033] When this device is in use, a woven bag can be directly used to receive the crushed straw. Through the setting of the bag mouth clamping device, the bag mouth of the woven bag can be directly fixed, and there is no need for someone to hold the bag mouth. When fixing the woven bag, put the bag mouth on the outside of the output pipe 18, then turn the knob 22. The rotation of the knob 22 drives the bidirectional lead screw 21 to rotate, thereby driving the slider 23 and the clamping plate 24 to move towards each other and get closer. The bag mouth of the woven bag is clamped and fixed through the cooperation between the clamping plate 24 and the outer wall of the output pipe 18. Then tighten the locking nut 25 to lock the bidirectional lead screw 21 so that it cannot rotate.

[0034] The motor 8 drives the first rotating shaft 10 to rotate. The first rotating shaft 10 directly drives the gear 14 to rotate. Under the meshing transmission of the two groups of gears 14, the first crushing knife roller 3 and the second crushing knife roller 4 rotate synchronously. At the same time, the first rotating shaft 10 can drive the second rotating shaft 12 to rotate through the transmission between the first bevel gear 11 and the second bevel gear 13. Through the setting of the gear speed increaser 15, the rotational speed can be amplified, and the rotational speed of the pulley 16 at the bottom of the gear speed increaser 15 can be increased. The pulley 16 at the bottom of the gear speed increaser 15 drives the pulley 16 at the bottom of a set of rotating knife shafts 5 through the belt 17, and this set of rotating knife shafts 5 drives the pulley 16 at the bottom of another set of rotating knife shafts 5 through the belt 17, so that both sets of rotating knife shafts 5 can rotate at high speed. The straw entering the crushing chamber 2 is first preliminarily crushed by the first crushing knife roller 3 and the second crushing knife roller 4, and then drops, and is further cut and crushed by the blades 6 on the two sets of rotating knife shafts 5 rotating at high speed. Through the setting of the two synchronously operating cutting mechanisms, the crushing effect is effectively improved.

[0035] The bidirectional transmission device includes a transmission box 9 installed on the fixed frame 7. The first rotating shaft 10 is installed through and rotatably between the two ends of the transmission box 9. The first bevel gear 11 is sleeved on the outside of the first rotating shaft 10. The second rotating shaft 12 is installed through and rotatably at the bottom of the transmission box 9. The second bevel gear 13 is installed at the top of the second rotating shaft 12. The second bevel gear 13 and the first bevel gear 11 are meshed.

[0036] When the first rotating shaft 10 rotates, in addition to driving the gear 14 to rotate, it also drives the second rotating shaft 12 to rotate through the meshing transmission between the second bevel gear 13 and the first bevel gear 11, so as to output power in two directions simultaneously.

[0037] The output end of the motor 8 is connected to one end of the first rotating shaft 10, and one end of the first rotating shaft 10 is connected to one of the gears 14.

[0038] The motor 8 directly drives the first rotating shaft 10 to rotate, and drives the gear to rotate through the first rotating shaft 10, and then drives the first crushing knife roller 3 and the second crushing knife roller 4 to rotate.

[0039] The input shaft of the gear speed increaser 15 is connected to the bottom end of the second rotating shaft 12.

[0040] The second rotating shaft 12 drives the gear speed increaser 15 to rotate. Through the setting of the gear speed increaser 15, the rotational speed can be amplified. The operation of the gear speed increaser 15 drives two groups of rotary cutter shafts 5 to rotate through a belt 17.

[0041] The bag mouth clamping device includes a fixture mounting plate 19. A slide rail 20 is mounted on the side of the fixture mounting plate 19. A bidirectional lead screw 21 is rotatably mounted inside the slide rail 20 and a slider 23 is slidably provided. The bidirectional lead screw 21 and the slider 23 are threadedly connected. The top of the bidirectional lead screw 21 is connected to a knob 22. A clamping plate 24 is mounted on the side of the slider 23.

[0042] When the device is in use, a woven bag can be directly used to receive the crushed straw. Through the setting of the bag mouth clamping device, the bag mouth of the woven bag can be directly fixed without the need for someone to hold the bag mouth. When fixing the woven bag, the bag mouth is sleeved outside the output pipe 18, and then the knob 22 can be rotated. The rotation of the knob 22 drives the bidirectional lead screw 21 to rotate, thereby driving the slider 23 together with the clamping plate 24 to move towards each other and approach each other. The bag mouth of the woven bag is clamped and fixed through the cooperation between the clamping plate 24 and the outer wall of the output pipe 18.

[0043] A locking nut 25 is threadedly mounted on the outer side of the top of the bidirectional lead screw 21.

[0044] After completing the clamping of the bag mouth of the woven bag, tighten the locking nut 25 to lock the bidirectional lead screw 21 so that it cannot rotate, thereby avoiding loosening of the clamping.

[0045] Working principle and usage process of the utility model: When this device is in use, a woven bag can be directly used to receive the crushed straw. Through the setting of the bag mouth clamping device, the bag mouth of the woven bag can be directly fixed, without the need for someone to hold the bag mouth. When fixing the woven bag, put the bag mouth on the outside of the output pipe 18, then rotate the knob 22. The rotation of the knob 22 drives the bidirectional lead screw 21 to rotate, thereby driving the slider 23 and the clamping plate 24 to move towards each other and get closer. The bag mouth of the woven bag is clamped and fixed through the cooperation between the clamping plate 24 and the outer wall of the output pipe 18. Then tighten the locking nut 25 to lock the bidirectional lead screw 21 so that it cannot rotate. When crushing the straw, put the straw into the inside of the crushing chamber 2 from the top of the crushing chamber 2. The motor 8 drives the first rotating shaft 10 to rotate. The first rotating shaft 10 directly drives the gear 14 to rotate. Under the meshing transmission of the two groups of gears 14, the first crushing knife roller 3 and the second crushing knife roller 4 rotate synchronously. At the same time, the first rotating shaft 10 can drive the second rotating shaft 12 to rotate through the transmission between the first bevel gear 11 and the second bevel gear 13. Through the setting of the gear speed increaser 15, the rotation speed can be amplified, and the rotation speed of the pulley 16 at the bottom of the gear speed increaser 15 can be increased. The pulley 16 at the bottom of the gear speed increaser 15 drives the pulley 16 at the bottom of a set of rotary knife shafts 5 to rotate through the belt 17, and this set of rotary knife shafts 5 drives the pulley 16 at the bottom of another set of rotary knife shafts 5 to rotate through the belt 17, so that both sets of rotary knife shafts 5 can rotate at high speed. The straw entering the crushing chamber 2 is first preliminarily crushed by the first crushing knife roller 3 and the second crushing knife roller 4, and then drops, and is further cut and crushed by the blades 6 on the two sets of high-speed rotating rotary knife shafts 5. Through the setting of a set of motors driving two synchronously operating cutting mechanisms, the crushing effect is effectively improved.
