Description

Technical Field

[0001] This utility model relates to the field of agricultural waste treatment technology, and more specifically, to an agricultural waste resource utilization and treatment machine. Background Technology

[0002] Agricultural waste is a general term for waste generated from agricultural production, agricultural product processing, livestock and poultry farming, and rural residents' daily lives. Agricultural straw can be used to produce biogas and as organic fertilizer. It is also used as roughage for livestock and as bedding for pens. By mixing livestock manure and pen bedding, or by mixing chopped straw with an appropriate amount of human and animal excrement for high-temperature composting, a large number of pathogens and parasite eggs in human and animal excrement, as well as plant pests and weed seeds hidden in various straws, can be killed after a short period of fermentation. Then, the compost is put into a biogas digester for fermentation to produce biogas. This treatment method can provide biogas fuel and obtain high-quality organic fertilizer. The manure is sealed to prevent fly breeding. This treatment method has been widely used in rural China.

[0003] A search revealed that application number CN202221354421.0 discloses an agricultural waste resource utilization and treatment device, relating to the technical field of treatment equipment, including an installation frame and a cutting assembly; the installation frame has a control switch assembly installed on its front side, a belt conveyor installed inside the installation frame, and a crushing assembly installed on the right end of the lower side of the installation frame; the cutting assembly includes a bracket, a fixing plate, a U-shaped rod, a connecting strip, a spring, a blade holder, and a blade, with two corresponding brackets fixed on the upper side of the installation frame, and a fixing plate fixed on the corresponding inner side of the two brackets, two corresponding sliding holes opened on the upper side of the fixing plate, with a U-shaped rod slidably connected inside the two sliding holes, a connecting strip fixed on the lower end face of the U-shaped rod, and two corresponding springs sleeved on the circumference of the U-shaped rod, enabling thorough crushing of straw.

[0004] Although the aforementioned patent can cut and crush waste such as straw, the equipment still has the following defects during normal use: the waste such as straw will contain a large amount of impurities such as stones and wastewater. If it is directly crushed and used, the wastewater will be affected in the subsequent fermentation and fertilizer production if it is not separated. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing agricultural waste resource utilization and processing machines cannot separate stones or wastewater mixed in with straw and other wastes, which affects the fermentation and fertilizer production of waste.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] An agricultural waste resource utilization and processing machine includes a processing tank and a crushing mechanism disposed inside the processing tank, and further includes:

[0008] A collection frame is provided at the bottom of the processing box. A fixed frame is provided inside the collection frame, and an elastic filter screen is provided on the inner wall of the fixed frame.

[0009] The extrusion mechanism includes a cylinder mounted on the outer wall of the processing chamber, a piston rod mounted on the cylinder output shaft, a pressure plate mounted on the end of the piston rod away from the cylinder and slidably connected to the top two edges of the fixed frame, and a plurality of piercing pins mounted on the surface of the pressure plate; and

[0010] A pulling mechanism, located at the bottom of the collection frame, is used to reciprocate the pulling of the elastic filter screen to continuously bounce up the waste accumulated on the elastic filter screen.

[0011] As a preferred technical solution of this application, the pulling mechanism includes a box body disposed at the bottom of the collection frame, a pull rod slidably disposed at the top of the box body and extending upward through the bottom of the collection frame, a pull rope disposed between the top of the pull rod and the bottom of the elastic filter screen, and a drive component disposed inside the box body for driving the pull rod to slide back and forth.

[0012] As a preferred technical solution of this application, the drive assembly includes a first motor disposed on the inner side wall of the housing, a cam disposed on the output shaft of the first motor, a pulley disposed at the bottom of the pull rod and in contact with the cam, and a first spring disposed on the inner wall of the pull rod located inside the housing.

[0013] As a preferred technical solution of this application, the crushing mechanism includes a second motor symmetrically arranged at both ends of the processing box near the top side wall and a crushing roller arranged on the output shaft of the second motor.

[0014] As a preferred technical solution of this application, a feeding hopper is provided at the top inlet of the processing box, and baffles are provided on both sides of the bottom edge of the feeding hopper above the crushing roller.

[0015] As a preferred technical solution of this application, both sides of the inner wall of the processing box are rotatably connected with outwardly extending rotating shafts. The rotating shafts are provided with a toggle plate on the rod wall inside the processing box, and a rotating mechanism is provided at the end of the rotating shafts outside the processing box.

[0016] As a preferred technical solution of this application, the rotating mechanism includes a first rotating rod and a second rotating rod rotatably disposed on the outer wall of the processing box at the end face of the crushing roller, an incomplete gear disposed on the wall of the second rotating rod, a complete gear disposed at one end of the rotating shaft located outside the processing box and meshing with the incomplete gear, a second spring sleeved on the rod wall located between the processing box and the complete gear, and a belt for transmission disposed between the first rotating rod and the second rotating rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Waste materials such as straw are placed into the processing bin. The crushing mechanism crushes the straw waste, which then falls onto an elastic filter screen. A pulling mechanism, activated by the first motor, causes a cam, pulley, and spring to move a pull rod up and down, pulling the elastic filter screen repeatedly. This causes the filter screen to continuously lift the waste material accumulated on its surface, allowing stones and other impurities to fall through the screen into a collection box. Then, a pressing mechanism activates the cylinder, which, through a piston rod, moves a pressure plate to press the waste, squeezing out the wastewater and allowing it to fall through the filter screen into the collection box. This solves the problem in existing technologies where crushed straw and other waste cannot separate the stones, wastewater, and other impurities.

[0019] 2. When the crushing mechanism crushes waste such as straw, the first rotating rod, the second rotating rod, the belt, the complete gear, the incomplete gear and the second spring can drive the rotating shaft to rotate back and forth. Therefore, the crushed waste falling down will be pushed up and down by the agitator plate, which can not only break up the waste and prevent some waste from sticking together, but also shake off the stones, wastewater and other impurities mixed in the waste, further improving the speed of separating impurities in the waste.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figures 1 to 4 As shown, this embodiment proposes an agricultural waste resource utilization processing machine, including a processing box 1 and a crushing mechanism disposed inside the processing box 1, as well as a collection frame 5, a squeezing mechanism and a pulling mechanism. The collection frame 5 is disposed at the bottom of the processing box 1, and a fixed frame 2 is disposed inside the collection frame 5. An elastic filter screen 201 is disposed on the inner wall of the fixed frame 2. The squeezing mechanism is disposed inside the processing box 1 and is used to squeeze the crushed waste. The pulling mechanism is disposed at the bottom of the collection frame 5 and is used to reciprocate to pull the elastic filter screen 201 so as to continuously bounce up the waste accumulated on the elastic filter screen 201.

[0030] When using waste materials such as straw for fertilizer production, the waste needs to be crushed first. Workers place the straw waste into the processing box 1. A crushing mechanism first crushes the straw, and the crushed waste falls onto an elastic filter screen 201. A pressing mechanism then squeezes the waste, expelling the wastewater mixed in with it. The wastewater then falls through the elastic filter screen 201 into the collection box 5. Finally, a pulling mechanism repeatedly pulls the elastic filter screen 201, causing it to bounce up the waste accumulated on its surface. This shakes off some of the stones and other debris mixed in with the waste, allowing them to fall through the elastic filter screen 201 into the collection box 5. This process separates the stones, debris, and wastewater mixed in with the crushed waste, improving the subsequent fertilizer production efficiency.

[0031] The crushing mechanism includes two second motors 9 symmetrically arranged at both ends of the processing box 1 near the top side wall and crushing rollers 901 arranged on the output shaft of the second motors 9. A feeding hopper 10 is provided at the top feed inlet of the processing box 1, and baffles 1001 are provided on both sides of the bottom edge of the feeding hopper 10 above the crushing rollers 901. When straw is put into the feeding hopper 10, the two second motors 9 are started to drive the two crushing rollers 901 to rotate relative to each other, thereby crushing the straw. The baffles 1001 prevent the straw from falling into the gap between the crushing rollers 901 and the inner wall of the processing box 1 and thus preventing it from being crushed.

[0032] Specifically, such as Figures 1 to 5 As shown, in a preferred embodiment, based on the above method, the extrusion mechanism further includes a cylinder 3 disposed on the outer wall of the processing box 1, a piston rod disposed on the output shaft of the cylinder 3, a pressure plate 4 disposed on the end of the piston rod away from the cylinder 3 and slidably connected to the top two sides of the fixed frame 2, and a plurality of piercing columns 401 disposed on the surface of the pressure plate 4.

[0033] The pulling mechanism includes a housing 6 disposed at the bottom of the collection frame 5, a pull rod 7 slidably disposed at the top of the housing 6 and extending upward through the bottom of the collection frame 5, a pull rope 701 disposed between the top of the pull rod 7 and the bottom of the elastic filter screen 201, and a drive assembly disposed inside the housing 6 for driving the pull rod 7 to slide back and forth.

[0034] The drive assembly includes a first motor 8 disposed on the inner side wall of the housing 6, a cam 801 disposed on the output shaft of the first motor 8, a pulley 702 disposed at the bottom of the pull rod 7 and in contact with the cam 801, and a first spring 703 disposed on the inner wall of the pull rod 7 located inside the housing 6.

[0035] When the crushed straw waste falls onto the elastic filter screen 201, the cylinder 3 is activated, driving the pressure plate 4 to move via the piston rod. The pressure plate 4 squeezes the waste, expelling the wastewater mixed in with it. The wastewater then falls through the elastic filter screen 201 into the collection frame 5. The piercing posts 401 on the surface of the pressure plate 4 can penetrate the waste during the squeezing process, further increasing the speed at which the wastewater flows out. Then, the first motor 8 is activated, driving the cam 801 connected to its output shaft to rotate. When the cam 801 rotates to its small end contacting the pulley 702, it squeezes the pull rod 7 upwards and compresses the first spring 703. When the cam 801 rotates to its large end contacting the pulley 702... Upon contact, the first spring 703 is released from its force, causing the pull rod 7 to move downwards and reset. Therefore, the pull rod 7 pulls the elastic filter screen 201 back and forth through the pull rope 701. The elastic filter screen 201 bounces up the waste accumulated on its surface, thereby shaking out the stones and other debris mixed in with the waste and letting them fall into the collection frame 5 through the elastic filter screen 201. Moreover, the equipment can be supported by the support legs 501 set at the bottom of the collection frame 5. Finally, by opening the sealing plates on the side walls of the processing box 1 and the collection frame 5, the crushed waste and the debris and wastewater separated from the waste can be taken out. Therefore, the stones, debris and wastewater mixed in with the crushed waste can be separated and processed, which facilitates the improvement of the subsequent fertilizer production effect of the waste.

[0036] like Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, further, both sides of the inner wall of the processing box 1 are rotatably connected to outwardly extending rotating shafts 11, the rotating shafts 11 are provided with a lever plate 1101 on the rod wall inside the processing box 1, and the rotating shafts 11 are provided with a rotating mechanism at the end outside the processing box 1.

[0037] The rotating mechanism includes a first rotating rod 902 and a second rotating rod 12 rotatably disposed on the outer wall of the processing box 1 at the end face of the crushing roller 901, an incomplete gear 1201 disposed on the rod wall of the second rotating rod 12, a complete gear 1102 disposed at one end of the rotating shaft 11 located outside the processing box 1 and meshing with the incomplete gear 1201, a second spring 1103 sleeved on the rod wall of the rotating shaft 11 located between the processing box 1 and the complete gear 1102, and a belt 1202 that is driven between the first rotating rod 902 and the second rotating rod 12.

[0038] When the second motor 9 drives the crushing roller 901 to rotate and crush the straw, the crushing roller 901 also drives the second rotating rod 12 to rotate through the first rotating rod 902 and the belt 1202. The second rotating rod 12 then drives the incomplete gear 1201 to rotate. When the incomplete gear 1201 rotates to the toothed side and contacts the complete gear 1102, it can drive the complete gear 1102 and the rotating shaft 11 to rotate and cause the second spring 1103 to twist. When the incomplete gear 1201 rotates to the toothless side and contacts the complete gear 1102, the second spring 1103 will be released and drive the rotating shaft 11 to reverse. Therefore, the rotating shaft 11 will drive the agitator plate 1101 to flip back and forth, continuously lifting up the falling waste. This not only breaks up the crushed waste, but also shakes off and separates the stones, debris and wastewater mixed in the waste. In order to prevent the rotating mechanism from being affected by external objects, a protective cover 101 can be installed outside the processing box 1 to shield and protect the components of the rotating mechanism.

[0039] The working principle of this utility model is as follows: When it is necessary to use waste materials such as straw for fertilizer production, the straw waste is put into the processing box 1. Then, the two second motors 9 are started to drive the two crushing rollers 901 to rotate relative to each other, thereby crushing the straw. The crushed straw waste will fall onto the elastic filter screen 201. At this time, the cylinder 3 can be started to work, and the piston rod drives the pressure plate 4 to move. The pressure plate 4 squeezes the waste, thereby squeezing out the wastewater mixed in with the waste. The wastewater will fall into the collection frame 5 through the elastic filter screen 201. Then, the first motor 8 is started to drive the cam 801 connected to its output shaft to rotate. When the cam 801 rotates to the point where the small end contacts the pulley 702, it will squeeze the pull rod 7 to move upward and compress the first spring 703. When the cam 801 rotates to the point where its large end contacts the pulley 702, the first spring 703 will be released from its force, causing the pull rod 7 to move downwards and reset. Therefore, the pull rod 7 will pull the elastic filter screen 201 back and forth through the pull rope 701. The elastic filter screen 201 will bounce up the waste accumulated on its surface, thereby shaking out the stones and other debris mixed in the waste and letting them fall into the collection frame 5 through the elastic filter screen 201. Thus, the stones and debris mixed in the crushed waste and the wastewater can be separated and treated, which is conducive to improving the fertilizer production effect of the waste.

[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
