[0001] The invention belongs to the technical field of fermentation equipment, and specifically refers to an agricultural and forestry waste fermentation device. Background Art

[0002] Agricultural and forestry wastes such as straw, branches and leaves can produce clean energy gas after fermentation, which has very high utilization value. The agricultural and forestry waste fermentation device in the prior art has the following technical problems when in use: (1) The existing technology generally uses structures with relatively simple functions to assemble and realize the overall function. For example, the fermentation process requires water replenishment and compost turning, and these operations usually require manual operation or are achieved through independent control mechanisms, and the equipment is relatively complex; (2) The process of feeding agricultural and forestry waste and discharging residues is rather complicated.

[0006] In order to adjust the posture of the material cylinder, thereby facilitating material feeding and automatic slag discharge, an alternating clamping method is adopted to alternately clamp and lock the material cylinder between the third bracket and the fermentation cylinder. The clamping and locking are achieved by means of a locking piece. A locking disk is fixedly provided on the side wall of the third bracket close to the material cylinder, a circular array of locking pieces away from the fermentation cylinder is distributed on the outside of the locking disk, and a circular array of locking pieces close to the fermentation cylinder is distributed on the outside of the end of the fermentation cylinder.

[0007] The alternating clamping control of the locking piece is achieved by the lock-changing piece, which includes a cylinder, a transverse tube one, a transverse tube two, a hydraulic plate and an electric push rod.

At this time, the friction blocks in the convex shell connected to the annular tube one shrink into the convex shell due to the transfer of hydraulic oil into the oil cylinder, and do not contact the outer wall of the end of the fermentation cylinder. At this time, the material cylinder is locked with the locking disk by the friction clamping action of the friction blocks on the annular tube two, so that it can remain stationary. On the contrary, when the electric push rod is extended, the movement of the hydraulic plate causes the hydraulic oil on both sides of the oil cylinder to be transferred, and the friction blocks in the convex shell connected to the annular tube two will shrink and no longer clamp the locking disk, while the friction blocks in the convex shell connected to the annular tube one will extend out and clamp the outer wall of the end of the fermentation cylinder.

The water spray holes are respectively connected with the water spray channels.

The spiral blades extend to the inside of the material cylinder and are used to move materials in and out of the fermentation cylinder. A spiral turning plate is fixedly provided on the circumferential inner wall of the fermentation cylinder.

[0009] Furthermore, an air outlet valve is fixedly provided on the upper end of the fixed column, the air outlet valve is coaxially arranged with the fermentation cylinder, the air outlet valve passes through the side walls of the liquid inlet cylinder and the end of the fermentation cylinder, a sealing plate is hinged on the upper wall of the material cylinder, and a telescopic switch is provided on the side wall of the third bracket, and the telescopic switch is electrically connected to the electric push rod for controlling the extension and contraction of the electric push rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) The special pipeline connection and pipeline switching control method of the hydraulic drive component can quickly control the flow path and direction of the water body, so that the fermentation cylinder can rotate forward and backward. The spiral structure inside the forward-rotating fermentation cylinder can quickly feed agricultural and forestry waste and automatically turn the pile. The reverse-rotating fermentation cylinder can quickly discharge agricultural and forestry waste residues from the fermentation cylinder. While driving the fermentation cylinder to rotate, the hydraulic drive component can also use the pipeline set in the fermentation cylinder to replenish water inside the fermentation cylinder, which significantly improves the fermentation efficiency. (2) The material cylinder alternately clamps and locks the third bracket and the fermentation cylinder with the help of a locking member that alternately switches between the two sides, thereby realizing the switching between the rotation and static states. When the electric push rod is in the retracted state, the material cylinder is locked with the locking disk through the friction clamping action of the friction block on the ring tube 2, thereby being able to maintain a static state. When the electric push rod is in the extended state, the material cylinder is locked with the fermentation cylinder through the friction clamping action of the friction block on the ring tube 1, thereby being able to rotate with the fermentation cylinder and adjust its posture. The switching of the above states enables the material cylinder to switch quickly and remain stable during the feeding and slag discharge processes. During the feeding process, the opening of the material cylinder faces upwards for easy feeding. During the slag discharge process, the opening of the material cylinder tilts downward for easy slag discharge. (3) The fermentation cylinder and the material tank use the spiral structure and the gravity of the agricultural and forestry waste to realize the feeding, turning and slag discharge. The overall operation method is very simple, which effectively solves the problem that the agricultural and forestry waste fermentation equipment in the prior art requires independent control devices to operate during the feeding, water replenishment, turning and slag discharge stages, the equipment is relatively complex and the operation efficiency is low.

[0024] The working process of this embodiment is divided into four stages: feeding, water replenishment, fermentation, and slag discharge: Feeding stage: the operator opens the sealing plate 35, the electric push rod 325 is in a retracted state, the hydraulic plate 324 is close to the end of the horizontal tube 2 323, and the convex shell 311 connected to the annular tube 2 34 causes the friction block 312 of this part to extend out of the convex shell 311 due to the hydraulic action and clamp the circumferential outer wall of the locking disk 131. At this time, the friction block 312 in the convex shell 311 connected to the annular tube 1 33 is retracted into the convex shell 311 due to the transfer of hydraulic oil into the oil cylinder 321, and does not contact the outer wall of the end of the fermentation cylinder 2. The material cylinder 3 is locked with the locking disk 131 by the friction clamping action of the friction block 312 on the annular tube 2 34, so that it can remain stationary, and the agricultural and forestry waste is sent into the material cylinder 3. The water pump 42 is running to start feeding the fermentation cylinder 2. In the initial state, the state of the hydraulic drive component 4 is as follows Figure 3-Figure 5 As shown, the hose 1 4322 is aligned and connected with the hard pipe 1 4311, the hose 2 4323 is aligned and connected with the hard pipe 2 4312, the T-shaped three-way channel 4521 inside the three-way column 452 connects the hard pipe 3 4411 and the hard pipe 2 4312, and the lower end of the hard pipe 4511 is blocked by the three-way column 452, and the water pump 42 runs and drives the water inside the pressure water tank 41 to flow back along the path of the hose 1 4322, the hard pipe 1 4311, the power cylinder 441, the hard pipe 3 4411, the T-shaped three-way channel 4521, the hard pipe 2 4312 and the hose 2 4323 Pressure water tank 41, during this process, the impeller 442 rotates due to the action of water flow, driving the driving gear 443 to rotate, thereby rotating the gear ring 22, thereby rotating the fermentation cylinder 2 as a whole, and the fermentation cylinder 2 drives the spiral blade 24 and the spiral turning plate 25 to rotate, and the spiral blade 24 moves the agricultural and forestry waste inside the material cylinder 3. Due to the spiral guiding action and the gravity of the agricultural and forestry waste, the agricultural and forestry waste will gradually be moved into the fermentation cylinder 2, and then the spiral turning plate 25 continues to move the agricultural and forestry waste, causing the agricultural and forestry waste to roll inside the fermentation cylinder 2.

[0025] Water replenishment stage: the agricultural and forestry waste needs to be replenished with water to improve the fermentation efficiency. The operator turns the knob 453 and rotates it 90°. At this time, the T-shaped three-way channel 4521 connects the hard pipe three 4411 and the hard pipe four 4511, while the hard pipe two 4312 is blocked. The water inside the pressure water tank 41 enters the liquid inlet cylinder 46 along the hose one 4322, the hard pipe one 4311, the power cylinder 441, the hard pipe three 4411, the T-shaped three-way channel 4521, and the hard pipe four 4511, and enters each water spray channel 23, and then is sprayed from the water spray hole 21 to the inside of the fermentation cylinder 2, thereby increasing the humidity of the agricultural and forestry waste.

[0026] Fermentation stage: the sealing plate 35 is closed, and the interior of the fermentation cylinder 2 and the material cylinder 3 are kept in a closed space for anaerobic fermentation. When the agricultural and forestry waste needs to be turned over during the process, the fermentation cylinder 2 is rotated using the control method of the feeding stage. The energy gas generated during the fermentation process is discharged from the outlet valve 471 and provided to the operator.

[0027] Slag discharge stage: after the fermentation of agricultural and forestry waste is completed, the agricultural and forestry waste residues need to be discharged from the equipment.
