[0002] Agricultural waste is also called agricultural garbage. According to its composition, it mainly includes two categories: plant fiber waste and livestock and poultry manure. Agricultural straw can be used to produce biogas and become agricultural organic fertilizer. It is also roughage for livestock and bedding for pens. Poultry and livestock manure and bedding for pens, or straw mixed with an appropriate amount of human and animal feces and urine for high-temperature composting. After a short period of fermentation, a large number of pathogenic bacteria and parasite eggs in human and animal feces, plant pests hidden in various straws, and various weed seeds can be killed.

[0035] The fermentation mechanism 6 includes a barrel body 601, and two reinforcing plates 602 are fixedly connected at the center of the side of the barrel body 601. The reinforcing plates 602 are used to enhance the overall support strength of the barrel body 601. Two top plates 603 are arranged on the inner side of the top of the barrel body 601. The top plates 603 are used to enclose the outer side of the inlet and outlet and support the bottom end of the drum door 604. The top ends of the two top plates 603 are slidably connected to the drum door 604. The drum door 604 is used to support the top of the barrel body 601. The inlet and outlet ports are enclosed to prevent waste crops from falling out of the barrel body 601, and rubber sealing strips are processed around the outer side of the drum door 604 to improve the sealing performance of the drum door 604 and prevent the fermentation liquid of waste crops from seeping out of the drum door 604. A plurality of electric telescopic rods 605 are evenly fixed to the outer side of the drum door 604. The electric telescopic rods 605 are used to control the opening and closing of the drum door 604, so as to facilitate the delivery of the fermentation liquid to the inside of the barrel body 601. The waste crops for fermentation composting or the waste crops after fermentation are discharged from the barrel body 601. The barrel body 601 is provided with a squeezing member 606 inside, which is used to squeeze the waste crops inside the barrel body 601 in a centered manner, so that the crops can be gathered to the inner center of the barrel body 601, which is convenient for discharging the fermented waste crops from the barrel body 601, and the fermentation liquid generated when the waste crops are fermented can be squeezed out from it during the squeezing process.

The outer sides of multiple electric telescopic rods 605 are fixedly connected to the top inner wall of the barrel body 601.

[0036] In this embodiment, preferably, a material inlet and outlet is opened at the top of the barrel body 601, and two top plates 603 are fixedly connected to the inner and outer bottom ends of the material inlet and outlet.

[0037] In this embodiment, preferably, the extrusion member 606 includes a motor housing 6061, and a motor 1 6062 is threadedly connected to one side of the motor housing 6061 through a flange. The motor 1 6062 is a servo motor, and is connected to an external power supply and an electrical control panel arranged on the top of the front surface of the side baffle 3 through a connecting line. The motor 1 6062 is used to provide power to the support rod 6063, thereby driving the support rod 6063 to rotate in the forward direction or the reverse direction. The outer wall of the output shaft of the motor 1 6062 is locked and connected to the support rod 6063 through a coupling. 63, the support rod 6063 is used to support the pressure plate 6065 and the heating rod 6066, and the outer top and bottom of the support rod 6063 are symmetrically provided with limit rods 6064, which are used to support the pressure plate 6065 and limit the movement stroke of the pressure plate 6065. The outer wall of the limit rod 6064 is slidably connected with the pressure plate 6065, and the pressure plate 6065 is used to squeeze the waste crops fermented in the barrel 601, so as to compact the waste crops in the fermentation process to the middle, and to stop the waste crops from fermenting. The fermentation liquid produced in the barrel 601 is filtered out from the inside, which is convenient for discharging the filtered fermentation liquid. A heating rod 6066 is sleeved at the center of the outer wall of the support rod 6063. The heating rod 6066 is used to heat the waste crops inside the barrel 601, so that the fermentation temperature of the waste crops can be better controlled. A temperature sensor 6067 is fixedly connected to the outside of the heating rod 6066. The temperature sensor 6067 is used to monitor the fermentation temperature of the waste crops inside the barrel 601 in real time. The motor housing 6061 is fixedly connected to one side to strengthen the plate 602. On the side, the motor housing 6061 is used to fix the motor 1 6062 and support the side of the barrel body 601, and the other side of the motor housing 6061 is rotatably connected to the top of the vertical plate 2 on one side, and the output shaft on the side of the motor 1 6062 is arranged through the inner center of the reinforced disk 602 on one side, and the other side of the support rod 6063 is rotatably connected to the side center of the hollow cover 608, and the side of the limit rod 6064 is fixed to the top and bottom ends on both sides of the inner wall of the barrel body 601, and the limit rods 6064 are symmetrical with each other with the support rod 6063 as the central axis.

[0038] In this embodiment, preferably, mutually symmetrical threads are processed on both sides of the outer wall of the support rod 6063. By processing mutually symmetrical threads on both sides of the outer wall of the support rod 6063, when the support rod 6063 rotates, the two pressure plates 6065 can be synchronously driven to move in opposite directions, that is, to move to the inside of the barrel body 601 or to the outside of the barrel body 601 at the same time, thereby driving the pressure plates 6065 to centrally squeeze the waste crops fermented inside the barrel body 601 and gather them into the inside of the barrel body 601. The center of the hollow cover 608 is connected to the wire hole, and the wire hole is used for wiring the wires connecting the heating rod 6066 and the temperature sensor 6067 to the outside. A plurality of filter holes are evenly arranged inside the pressure plate 6065 on one side for filtering the squeezed fermentation liquid from the discarded crops.

[0039] In this embodiment, preferably, an electrical control panel and a temperature display screen are provided at the top of the front surface of one side baffle door 3, the electrical control panel is used to control the operation of the electrical parts in the device, and the temperature display screen is used to monitor the fermentation temperature inside the barrel body 601.

[0040] In summary, when the waste crops are fermented and composted, the top cover 4 is opened from the top of the outer wall of the frame 1, so that the fermentation mechanism 6 arranged inside the frame 1 is exposed, and the synchronous operation of the multiple electric telescopic rods 605 can drive the drum door 604 to slide outward, so that the waste crops to be fermented can be put into the barrel body 601. After the waste crops are put in, the electric telescopic rods 605 are controlled to extend, so that the drum door 604 is reset, and the inlet and outlet ports opened on the outer wall of the barrel body 601 are closed again, so that the waste crops inside the barrel body 601 can be fermented. Through the operation of the temperature sensor, the temperature inside the barrel body 601 can be measured. The fermentation temperature of the waste crops is monitored in real time. When the fermentation temperature of the waste crops in the barrel body 601 does not meet the standard, the heating rod 6066 can be controlled to start working, so as to adjust the fermentation temperature of the waste crops, so that the ambient temperature in the barrel body 601 is more suitable for the fermentation of the waste crops. Since the heating rod 6066 is arranged with the support rod 6063 as the axis array, when the waste crops in the barrel body 601 are heated, the temperature can be raised more evenly, thereby improving the fermentation effect of the waste crops. In the process of fermenting the waste crops, some fermentation liquid will be produced. At this time, the motor 1 6062 in the extrusion component 606 can drive the support rod 6063 to rotate. The rod 6063 rotates. When the support rod 6063 rotates, since the two sides of its outer wall are processed with completely opposite threads, and the two pressure plates 6065 are threadedly connected to the outer wall of the support rod 6063, during the rotation of the support rod 6063, the two pressure plates 6065 will be driven to slide toward the inner center of the barrel body 601 at the same time, so that the waste crops inside the barrel body 601 can be squeezed. Through the operation of a plurality of filter holes inside the pressure plate 6065 on one side, the fermentation liquid generated during the fermentation of the waste crops can be filtered out from the waste crops, and the filtered fermentation liquid will be discharged from the inside of the barrel body 601 to the outer shell 70 through the drainage hole 607. 2, so that the generated fermentation liquid can be discharged through the drainage hole 713. When the fermentation liquid is squeezed out from the waste crops, the waste crops are gathered to the inner center of the barrel body 601, so that the waste crops after fermentation are discharged from the barrel body 601. After the fermentation liquid is squeezed out, the motor 1 6062 is controlled to reverse, so that the support rod 6063 can also rotate in the opposite direction, so that the two pressure plates 6065 threadedly connected on both sides of the outer wall of the support rod 6063 can slide toward the inner and outer sides of the barrel body 601 at the same time, so that the two pressure plates 6065 are restored to their original positions, so that the waste crops can be squeezed again in the future.

[0043] In this embodiment, preferably, the side of the hollow shaft 701 is rotatably connected to the inside of the side of the outer shell 702 and fixedly connected to the side of the barrel body 601, and the other side is rotatably connected to the top of the vertical plate 2 on the other side, and the outer wall of the hollow shaft 701 is extended to the outer wall of the vertical plate 2.

[0044] In the present embodiment, preferably, the discharging and transmission mechanism 7 also includes a transmission rod 709, and two spiral pieces 710 are fixedly connected to the outer side of the outer wall of the transmission rod 709. The two spiral pieces 710 are used to gather the waste crops discharged from the inside of the barrel body 601 to the inner center of the discharge hopper 703, so as to facilitate the knife wheel 711 to further process the waste crops after the fermentation and composting. A plurality of knife wheels 711 are evenly fixedly connected to the center of the outer wall of the transmission rod 709, and the knife wheel 711 is used to cut the waste crops after fermentation, so as to facilitate the use of the waste crops after fermentation, and eliminate the step of cutting and processing the waste crops after fermentation again, thereby improving the processing efficiency of the waste crops. The bottom end of each spiral blade 710 is provided with a baffle 712, which is used to enclose abandoned crops. A drainage hole 713 is provided at the top of one side baffle 712, which is used to discharge the fermentation liquid discharged from the barrel body 601.

The water-blocking plate is used to isolate the fermentation liquid discharged from the drainage hole 607.

[0046] In summary, after the waste crops are put into the fermentation mechanism 6, the motor 2 707 can drive the transmission belt 705 to rotate through the small pulley 706, thereby driving the large pulley 704 to rotate at the same time. Since the large pulley 704 is fixedly connected to the outer wall of the hollow shaft 701, and the hollow shaft 701 is fixedly connected to the side of the barrel body 601, when the large pulley 704 drives the hollow shaft 701 to rotate, it will also synchronously drive the barrel body 601 to rotate slowly, so that the waste crops in the barrel body 601 can be heated more evenly, and the fermentation efficiency and effect of the waste crops can be further improved. After the fermentation of the waste crops is completed, when the inlet and outlet ports opened on the outer wall of the barrel body 601 rotate to the inside of the shell 702, the motor 2 707 in the transmission and discharge mechanism temporarily stops working, and then the multiple electric telescopic rods 605 are simultaneously retracted. Through the cooperation of the multiple electric telescopic rods 605, the drum door 604 can be driven to slide outward, thereby canceling the enclosure of the inlet and outlet ports, and the The waste crops that have completed fermentation and composting inside the barrel body 601 are discharged from the inside. When the waste crops in the barrel body 601 are discharged, the multiple electric telescopic rods 605 are re-extended to drive the drum door 604 to reset, thereby re-enclosing the drum door 604. At this time, the second motor 707 starts to work again, and the motor 707 provides power to the small pulley 706, so that the transmission rod 709 can be driven to rotate through the small pulley 706. During the rotation of the transmission rod 709, the two spiral pieces 710 and the multiple cutter wheels 711 will be driven to rotate together, so as to cut off the discharged waste crops. Since the spiral directions of the two spiral pieces 710 are opposite, when the two spiral pieces 710 rotate at the same time, the waste crops accumulated on the top thereof can be gathered to the top of the cutter wheel 711, so that the multiple cutter wheels 711 can cut off the waste crops, and the cut waste crops are discharged through the bottom end of the discharge hopper 703, so that the rear end can use the waste crops after the waste fermentation and composting.

[0047] Embodiment 3

[0048] See also Figure 1-Figure 9As shown, the present embodiment is obtained by combining the first embodiment with the second embodiment. When the waste crops need to be fermented and composted, the waste crops are put into the fermentation mechanism 6. Through the cooperation of the heating rod 6066 and the temperature sensor 6067, the fermentation environment temperature of the waste crops can be monitored in real time, and the fermentation temperature inside the barrel 601 can be adjusted according to the fermentation requirements, thereby improving the fermentation efficiency of the waste crops. Through the operation of the discharging and transmission mechanism 7, during the fermentation of the waste crops, the barrel 601 can also be driven to rotate, so that the fermentation of the waste crops inside the barrel 601 is more uniform, thereby improving the fermentation effect. Since the waste crops will produce fermentation liquid during the fermentation process, the fermentation liquid can be squeezed out by the extrusion mechanism 7. The operation of component 606 can filter out the fermentation liquid produced by the waste crops during the fermentation process, and at the same time, the waste crops can be compacted to the inner center of the barrel body 601, so that the contact distance between the crops and the heating rod 6066 is closer, further improving the control of the fermentation temperature, and facilitating the subsequent discharge of the fermented waste crops from the barrel body 601. After the waste crops are discharged into the discharge hopper 703, the waste crops after fermentation can be cut off through the coordinated work of the transmission rod 709, the two spiral pieces 710 and the plurality of knife wheels 711, so that it is convenient to discharge them from the discharge hopper 703 and also convenient to use the waste crops after fermentation and composting.
