Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a dry yellow straw crusher with simultaneous hammer cutting. Background Technology

[0002] A straw crusher is an agricultural machine mainly used to process various crop straws and agricultural waste into smaller fragments for further processing and utilization. This not only helps reduce the environmental impact of agricultural waste, but also transforms these wastes into useful resources such as biomass energy, feed, or organic fertilizer.

[0003] Problems with existing technology:

[0004] When using a crusher to crush straw, most of the large straw particles produced by crushing fall directly to the bottom of the equipment. Since they cannot pass through the screen directly, large straw particles accumulate at the bottom of the equipment for a long time. This phenomenon will greatly affect the discharge of straw particles. Existing crushers do not have a structure for secondary crushing of large straw particles.

[0005] When straw is first put into the crusher, it enters the equipment in a clustered manner. When the clustered straw comes into contact with the crusher hammer, the impact force of the crusher hammer is buffered and weakened to varying degrees as the thickness of the straw clustered together. As a result, the crusher hammer cannot quickly and fully crush the straw, and most of the straw that is crushed in the first stage will directly accumulate at the bottom, thus aggravating the accumulation problem. Summary of the Invention

[0006] The purpose of this invention is to provide a dry yellow straw crusher with simultaneous hammer cutting, which can perform secondary crushing of large straw particles. In addition, it can lift and disperse the straw that has just been introduced into the machine body, and can improve the crushing force of the crushing hammer at the crushing position.

[0007] The specific technical solution adopted by this invention is as follows:

[0008] A hammer-cutting synchronized dry yellow straw crusher includes a crawler and a crusher body. The crawler is located at the input end of the crusher body, and a cutting mechanism for cutting straw is provided at one end of the crawler. A working shaft is rotatably assembled inside the crusher body, and assembly discs are fixedly assembled at equal intervals on the outer surface of the working shaft. Crushing hammers are rotatably assembled in an array on the inner side of two adjacent assembly discs. A separation structure is provided on one side of the crusher body, and the separation structure is used to reintroduce large straw particles into the crushing range. A magnetic crushing assist frame for improving crushing force is provided on the side of the crusher body near the input end. A pneumatic crushing assist mechanism for ensuring full contact between the straw and the crushing hammers is provided on the side of the crusher body near the input end.

[0009] Large straw particles after initial crushing enter the large particle separation channel and are discharged again to the crushing hammer by the vibrating return plate for secondary crushing.

[0010] When the end of the crusher moves to the position where it will contact the straw, it will be subjected to a repulsive force from the electromagnetic block, which is used to increase the crushing force of the crusher on the straw.

[0011] The high-pressure gas in the gas tank is used to lift the straw that has just been introduced into the crusher, thus dispersing the straw.

[0012] One end of the crusher body is equipped with a power motor, and the output end of the power motor is connected to one end of the working shaft through a sleeved chain two. The bottom of the crusher body and below the working shaft is equipped with a screw feeder for discharging straw particles. Inside the crusher body and above the screw feeder, a screen for filtering straw particles is installed. One end of the working shaft is connected to one end of the screw feeder through a sleeved chain three. The other end of the working shaft is fixedly equipped with a transmission sprocket one and a transmission sprocket two.

[0013] The input end of the crusher body is provided with a guide plate that contacts the end of the track machine, and the bottom of the inclined end of the guide plate is provided with an array of oblique nozzles.

[0014] The separation structure includes a negative pressure channel, a small particle separation channel, and a large particle separation channel. The negative pressure channel is located inside the crusher body and on the top side away from the guide plate. The small particle separation channel is located on the bottom side of the end of the negative pressure channel, and the end of the small particle separation channel is guided by a spiral feeder. The large particle separation channel is located on the bottom side of the middle of the negative pressure channel, and the end of the large particle separation channel is guided by a working shaft.

[0015] A return plate is rotatably assembled at the bottom of the large particle separation channel. Springs are equidistantly arranged on the inner wall of the crusher body and on the lower side of the return plate. A camshaft is rotatably assembled inside the crusher body and on the lower side of the return plate. One end of the camshaft extending out of the crusher body is connected to a transmission sprocket via a sleeved chain.

[0016] Magnetic blocks are fixedly installed at the end of the crushing hammer and on the side opposite to the crushed straw.

[0017] The magnetic crushing assist frame is fixedly installed on the outer wall of the crusher body, and inclined slides are opened at equal intervals inside. Sliders are slidably assembled inside the slides, and electromagnetic blocks are fixedly installed on the upper side wall of the sliders. A conductive sheet two is fixedly installed on the inner wall of one end of the top of the slide, and a conductive sheet one is fixedly installed on the surface of the upper side of the slider. The conductive sheet one and the conductive sheet two are electrically connected in contact.

[0018] A crankshaft is rotatably mounted at the lowest end inside the magnetic crushing assist frame, and a connecting rod is equidistantly connected to one side of the crankshaft. The end of the connecting rod is connected to the corresponding slider. One end of the crankshaft extends out of the magnetic crushing assist frame and is connected to the transmission sprocket two through a sleeved chain four.

[0019] An air pump body is fixedly assembled on the outer wall of one end of the tracked machine. The two air pump bodies are symmetrically arranged and have a power shaft assembled at the bottom. One end of the power shaft is connected to the output end of the power motor through a chain. The air inlet ends of the two air pump bodies are connected to an air extraction pipe. The air extraction pipe is connected to a negative pressure channel and a filter screen is installed at the connection. The air outlet ends of the two air pump bodies are connected to an air injection pipe.

[0020] The pneumatic crushing assist mechanism includes an air tank and a motor. An air duct is connected below the guide plate and at each oblique nozzle position. The air tank is connected to the end of the corresponding air duct. An air plug is movably installed inside the air tank, and a spring is connected to the side of the air plug away from the air duct. One end of the air tank is connected to a branch pipe for communicating with the air injection pipe. A valve is provided in the middle of the air duct, and a valve core rod is telescopically assembled inside the valve. A valve is provided in the middle of the branch pipe, and a valve core rod is telescopically assembled inside the valve.

[0021] A rotating rod is fixedly installed below the guide plate, and pry bars are equidistantly mounted on the surface of the rotating rod. The pry bars are arranged in an alternating manner. The ends of valve core rod one and valve core rod two are respectively connected to the two ends of the pry bars. The motor is fixedly installed on one side of the bottom of the guide plate, and the output end of the motor is fixedly connected to crankshaft two. Crankshaft two is connected to each pry bar through connecting rod two arranged at equal intervals.

[0022] The technical effects achieved by this invention are as follows:

[0023] (1) In this invention, after the large straw particles are separated after the initial crushing, they will come into contact with the crushing hammer again and be crushed again, giving the equipment a secondary crushing process for the large straw particles, solving the problem that the large straw particles cannot be fully crushed after settling to the bottom, and at the same time alleviating the problem of particle accumulation and blockage at the bottom of the equipment. In addition, the large straw particles and the crushing hammer can be evenly dispersed and come into contact with each other for a second time, which optimizes the effect of secondary crushing.

[0024] (2) In this invention, when the end of the crushing hammer moves to the position where it is about to contact the straw, it will be subjected to additional repulsive force from the electromagnetic block, thereby increasing the kinetic energy of the end of the crushing hammer at that point, and thus directly increasing the force of crushing the straw, thereby optimizing the straw crushing effect. In addition, the electromagnetic block is only energized when it moves to the limit position. This design can reduce the electrical energy consumed by continuous energization.

[0025] (3) In this invention, by raising the straw that has just been introduced into the crusher, the straw that has gathered together can be dispersed, and the dispersed straw can be crushed more fully by the crushing hammer, thus solving the problem of the crushing force being buffered due to the gathering of straw and optimizing the crushing effect.

[0039] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0040] like Figure 1-11 As shown, a hammer-cutting synchronized dry yellow straw crusher includes a crawler 1 and a crusher body 3. The crawler 1 is located at the input end of the crusher body 3, and a cutting mechanism 2 for cutting straw is provided at one end of the crawler 1. A working shaft 5 is rotatably assembled inside the crusher body 3, and assembly discs 501 are fixedly assembled at equal intervals on the outer surface of the working shaft 5. Crushing hammers 502 are rotatably assembled in an array on the inner side of two adjacent assembly discs 501. A separation structure is provided on one side inside the crusher body 3, and the separation structure is used to reintroduce large straw particles into the crushing range. A magnetic crushing assist frame 7 for improving crushing force is provided on the side of the crusher body 3 near the input end, and a pneumatic crushing assist mechanism 9 for ensuring full contact between the straw and the crushing hammers 502 is provided on the side of the crusher body 3 near the input end.

[0041] See attached document Figure 1-3The input end of the crusher body 3 is provided with a guide plate 301 that contacts the end of the crawler 1. One end of the crusher body 3 is provided with a power motor 4, and the output end of the power motor 4 is connected to one end of the working shaft 5 through a sleeved chain 401. The bottom of the crusher body 3 and below the working shaft 5 is provided with a screw feeder 306 for discharging straw particles. Inside the crusher body 3 and above the screw feeder 306, a screen 6 for filtering straw particles is installed. One end of the working shaft 5 and one end of the screw feeder 306 are connected through a sleeved chain 504. The other end of the working shaft 5 is fixedly installed with a first transmission sprocket 505 and a second transmission sprocket 506.

[0042] According to the above structure, the straw is transported from the tracked machine 1 to the crusher body 3. Before the straw enters the crusher body 3, it is first cut into short strips by the cutting mechanism 2. During the subsequent crushing operation, the power motor 4 operates and drives the working shaft 5 to rotate through the chain 401. Then, the straw is crushed by the rotation of each crushing hammer 502. The crushed straw will eventually fall into the screw feeder 306 through the screen 6 and be finally sent out by the screw feeder 306. The above process is all existing technology and will not be elaborated on here.

[0043] Example 1:

[0044] See attached document Figure 5 The separation structure includes a negative pressure channel 303, a small particle separation channel 304, and a large particle separation channel 305. The negative pressure channel 303 is located inside the crusher body 3 and on the top side away from the guide plate 301. The small particle separation channel 304 is located on the bottom side of the end of the negative pressure channel 303, and the end of the small particle separation channel 304 is guided by a screw feeder 306. The large particle separation channel 305 is located on the bottom side of the middle part of the negative pressure channel 303, and the end of the large particle separation channel 305 is guided by a working shaft 5.

[0045] See attached document Figure 2 , Figure 5-6 A return plate 307 is rotatably assembled at the bottom of the large particle separation channel 305. Springs 308 are equidistantly arranged on the inner wall of the crusher body 3 and on the lower side of the return plate 307. A camshaft 309 is rotatably assembled inside the crusher body 3 and on the lower side of the return plate 307. One end of the camshaft 309 extends out of the crusher body 3 and is connected to the transmission sprocket 505 through a chain 310.

[0046] According to the above structure, the straw crushed by the crushing hammer 502 will enter the negative pressure channel 303 under the action of centrifugal force and negative pressure. During the process, small particles will be directly discharged to the screw feeder 306 from the small particle separation channel 304 at the end, while large particles will be discharged back to the crushing hammer 502 from the large particle separation channel 305 in the middle. When the working shaft 5 rotates, it will drive the cam shaft 309 to rotate together through the chain 310. The return plate 307 in contact with the cam shaft 309 will be continuously lifted and have a "shaking" effect, and the straw falling into the large particle separation channel 305 will be affected. The straw particles are then evenly dispersed onto the crushing hammer 502 under this "shaking" effect. The spring 308 acts as a buffer for the return plate 307. In the above process, after the initial crushing, the large straw particles are separated and then come into secondary contact with the crushing hammer 502 for further crushing. This process enables the equipment to perform secondary crushing of the large straw particles, solving the problem that large straw particles cannot be fully crushed after settling to the bottom. It also alleviates the problem of particle accumulation and blockage at the bottom of the equipment. In addition, the large straw particles can be evenly dispersed and come into secondary contact with the crushing hammer 502, optimizing the effect of secondary crushing.

[0047] The working principle of this invention is as follows: the straw crushed by the crushing hammer 502 will enter the negative pressure channel 303 under the action of centrifugal force and negative pressure. During the process, small particles will be directly discharged to the screw feeder 306 from the small particle separation channel 304 at the end, while large particles will be discharged back to the crushing hammer 502 from the large particle separation channel 305 in the middle. When the working shaft 5 rotates, it will drive the cam shaft 309 to rotate together through the chain 310. The return plate 307 in contact with the cam shaft 309 will be continuously lifted and have a "shaking" effect. The straw particles falling into the large particle separation channel 305 will be evenly dispersed and sprinkled onto the crushing hammer 502 under this "shaking" effect.

[0048] Example 2:

[0049] See attached document Figure 4 Magnetic blocks 503 are fixedly installed at the end of the crushing hammer 502 and on the side away from the crushing straw.

[0050] See attached document Figure 7-8 The magnetic crushing assist frame 7 is fixedly installed on the outer wall of the crusher body 3, and inclined slides 701 are opened at equal intervals inside. Slider 702 is slidably assembled inside the slides 701, and electromagnetic blocks 703 are fixedly installed on the upper side wall of the slider 702. Conductive sheet 2 705 is fixedly installed on the inner wall of the top end of the slide 701, and conductive sheet 1 704 is fixedly installed on the upper surface of the slider 702. Conductive sheet 1 704 and conductive sheet 2 705 are electrically connected in contact.

[0051] See attached document Figure 7-8A crankshaft 707 is rotatably mounted at the lowest end inside the magnetic crushing assist frame 7, and a connecting rod 706 is equidistantly connected to one side of the crankshaft 707. The end of the connecting rod 706 is connected to the corresponding slider 702. One end of the crankshaft 707 extends out of the magnetic crushing assist frame 7 and is connected to the transmission sprocket 506 through a chain 708.

[0052] According to the above structure, when the working shaft 5 rotates, it drives the crankshaft 707 to rotate together via the chain 708. Each connecting rod 706 connected to the crankshaft 707 pushes the corresponding slider 702 to slide back and forth linearly. By controlling the transmission ratio between the working shaft 5 and the crankshaft 707, the magnetic block 503 at the end of the crusher 502 moves to... Figure 5 At point D (the point where the straw and the end of the crusher 502 are about to contact), the slider 702 has just moved to its uppermost position, and at this moment, the first conductive piece 704 is electrically connected to the second conductive piece 705. The electromagnetic block 703 is then energized and generates magnetic force. When the magnetic block 503 at point D is subjected to the repulsive force from the electromagnetic block 703, the corresponding crusher 502 will generate a force with its connection point as the center. Figure 5 The instantaneous circular motion along the L-path direction causes a sudden increase in the speed of the end of the crusher 502. This instantaneous kinetic energy is used to increase the crushing force of the straw. During the above process, when the end of the crusher 502 moves to the position where it is about to contact the straw, it will be subjected to an additional repulsive force from the electromagnetic block 703, thereby increasing the kinetic energy of the end of the crusher 502 at that point and directly increasing the crushing force of the straw. This optimizes the straw crushing effect. In addition, the electromagnetic block 703 is only energized when it moves to the limit position. This design can reduce the power consumption of continuous energization.

[0053] The working principle of this invention is as follows: When the working shaft 5 rotates, it drives the crankshaft 707 to rotate together via the chain 708. Each connecting rod 706 connected to the crankshaft 707 pushes the corresponding slider 702 to slide back and forth in a straight line. By controlling the transmission ratio between the working shaft 5 and the crankshaft 707, the magnetic block 503 at the end of the crusher 502 moves to... Figure 5 At point D, slider 702 has just reached its uppermost position, and at this moment, conductive sheet 704 is electrically connected to conductive sheet 705. Electromagnetic block 703 is then energized and generates magnetic force. When magnetic block 503 at point D is subjected to repulsive force from electromagnetic block 703, the corresponding crushing hammer 502 will generate a force with its connection point as the center. Figure 5 The instantaneous circular motion along the path L causes the speed of the end of the crusher 502 to increase sharply, thereby increasing the force of crushing the straw by using this instantaneous kinetic energy.

[0054] Example 3:

[0055] See attached document Figure 3 The bottom of the inclined end of the guide plate 301 is provided with an array of inclined nozzles 302.

[0056] See attached document Figure 1-2 , Figure 9 An air pump body 8 is fixedly assembled on the outer wall of one end of the tracked machine 1. The two air pump bodies 8 are symmetrically arranged and a power shaft 801 is assembled on the bottom together. One end of the power shaft 801 is connected to the output end of the power motor 4 through a chain 802. The air inlet ends of the two air pump bodies 8 are connected to an air extraction pipe 803. The air extraction pipe 803 is connected to the negative pressure channel 303 and a filter screen is installed at the connection. The air outlet ends of the two air pump bodies 8 are connected to an air injection pipe 804.

[0057] According to the above structure, when the power motor 4 is in motion, it will drive the power shaft 801 to rotate through the chain 802. At this time, the two air pump bodies 8 will operate simultaneously and extract the air in the negative pressure channel 303. The negative pressure channel 303 will generate negative pressure under this suction, which will facilitate the entry of straw particles.

[0058] See attached document Figure 9-11 The pneumatic crushing assist mechanism 9 includes an air tank 902 and a motor 913. An air pipe 901 is connected to the bottom of the guide plate 301 and to each oblique nozzle 302. The air tank 902 is connected to the end of the corresponding air pipe 901. An air plug 903 is movably installed inside the air tank 902. A spring 904 is connected to the side of the air plug 903 away from the air pipe 901. A branch pipe 907 for communicating with the air injection pipe 804 is connected to one end of the air tank 902. A valve 905 is provided in the middle of the air pipe 901. A valve core rod 906 is telescopically assembled inside the valve 905. A valve 908 is provided in the middle of the branch pipe 907. A valve core rod 909 is telescopically assembled inside the valve 907.

[0059] See attached document Figure 9-11 A rotating rod 910 is fixedly installed below the guide plate 301, and pry bars 911 are equidistantly mounted on the surface of the rotating rod 910. The pry bars 911 are arranged in an alternating manner. The ends of valve core rod 1 906 and valve core rod 2 909 are respectively connected to the two ends of the pry bars 911. The motor 913 is fixedly installed on one side of the bottom of the guide plate 301, and the output end of the motor 913 is fixedly connected to crankshaft 2 914. Crankshaft 2 914 is connected to each pry bar 911 through connecting rod 2 912 arranged equidistantly.

[0060] According to the above structure, the air pump body 8 injects the drawn air into the corresponding air storage tank 902 through the air injection pipe 804. The motor 913 is normally open and drives the crankshaft 914 to rotate. The connecting rod 912 connected to the crankshaft 914 drives the corresponding pry bar 911 to rotate reciprocally. The valve core rod 906 and valve core rod 909 connected to both ends of the pry bar 911 control the opening and closing of valve 905 and valve 908 respectively. When valve 908 is open, the corresponding valve... When valve 905 is closed, air from the air injection pipe 804 is injected into the corresponding air tank 902. The internal air plug 903 moves and compresses spring 904. When valve 905 opens, valve 908 closes. Under the pressure of the air and the action of spring 904, the gas in the corresponding air tank 902 quickly passes through the air passage pipe 901 and is ejected from the oblique nozzle 302. The impact of this high-pressure airflow can lift the straw that has just been introduced into the crusher body 3, and... Figure 10 As shown, the movement of the lever 911 is intermittent and the same, which eventually causes the oblique nozzles 302 to spray air intermittently. The above process, by raising the straw that has just been introduced into the crusher body 3, can disperse the straw that has gathered together. The dispersed straw can be more fully crushed by the crushing hammer 502, solving the problem of the crushing force being buffered due to the straw gathering and optimizing the crushing effect.

[0061] The working principle of this invention is as follows: When the power motor 4 is in motion, it drives the power shaft 801 to rotate via the chain 802. At this time, the two air pump bodies 8 will operate simultaneously and draw air from the negative pressure channel 303. The negative pressure channel 303 will generate negative pressure under this suction, which facilitates the entry of straw particles. The air pump body 8 injects the drawn air into the corresponding air storage tank 902 through the air injection pipe 804. The motor 913 is normally open and drives the crankshaft 914 to rotate. The connecting rod 912 connected to the crankshaft 914 will drive the corresponding pry bar 911 to rotate back and forth. The valve core rod 911 connected to both ends of the pry bar 911... 06 and valve core rod 909 will control the opening and closing of valve 1 905 and valve 2 908 respectively. When valve 2 908 is opened, valve 1 905 is closed. At this time, the air in the air injection pipe 804 will be injected into the corresponding air storage tank 902. The air plug 903 inside moves and squeezes spring 2 904. When valve 1 905 is opened, valve 2 908 is closed. At this time, under the action of air pressure and spring 2 904, the gas in the corresponding air storage tank 902 will quickly pass through the air passage pipe 901 and be sprayed out from the oblique nozzle 302. Under the impact of this high-pressure airflow, the straw that has just been introduced into the crusher body 3 can be lifted.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
