The outlet device 1-6 is disposed on the collection box 1-1 and connected to the collection chamber 1-2. The outlet device 1-6 is connected to the crushing device 3. The collection box 1-1 is provided with the separation device 2.

[0033] The excrement and straw mixed in with the excrement are collected by the collection device 1. The collection device 1 then separates the straw from the excrement. The excrement without straw enters the separation device 2 for solid-liquid separation. The straw is then crushed by the crushing device 3 and discharged together with the solid matter separated by the separation device 2 for further processing. The transmission device 1-3 pushes the excrement forward inside the collection chamber 1-2 while the driving device 1-4 screens the mixture of excrement.

[0034] Among them, such as Figure 1-11 As shown, the transmission device 1-3 includes a transmission shaft 1-3-1, a transmission roller 1-3-2, a transmission belt 1-3-3, and a through hole 1-3-4.

One of the transmission shafts 1-3-1 is equipped with a matching motor. The transmission shafts 1-3-1 are connected to the pushing device 1-4 through a transmission belt pulley set 1-5.

[0035] The drive shaft 1-3-1 drives the drive roller 1-3-2 to rotate, and the drive roller 1-3-2 drives the drive belt 1-3-3 to rotate, pushing the mixed excrement forward. At the same time, the pushing device 1-4 pushes the excrement above the drive belt 1-3-3 from left to right, and discharges the broken excrement through the through hole 1-3-4 to the separation device 2 for separation.

[0036] Among them, such as Figure 1-11As shown, the pushing device 1-4 includes a first connecting shaft 1-4-1, a first bevel gear 1-4-2, a second connecting shaft 1-4-3, a first half-bevel gear 1-4-4, a second half-bevel gear 1-4-5, a first gear 1-4-6, a movable gear frame 1-4-7, and a push plate 1-4-8.

The movable gear frame 1-4-7 is provided with two push plates 1-4-8 that push the excrement to move on the transmission belt 1-3-3.

[0037] A rotating connecting shaft 1-4-1 drives a second connecting shaft 1-4-3, which is equipped with a first half-bevel gear 1-4-4 and a second half-bevel gear 1-4-5, to reciprocate through a first bevel gear 1-4-2. The second connecting shaft 1-4-3 drives the first gear 1-4-6 to reciprocate. The reciprocating first gear 1-4-6 drives two push plates 1-4-8 to reciprocate and push the excrement through a movable gear frame 1-4-7.

[0038] Among them, such as Figure 1-11 As shown, the discharge device 1-6 includes a discharge port 1-6-1, a mounting cover 1-6-2, and a first connecting pipe 1-6-3. The discharge port 1-6-1 is disposed on the collection box 1-1, and the first connecting pipe 1-6-3 is disposed on the mounting cover 1-6-2. The mounting cover 1-6-2 and the discharge port 1-6-1 are connected, and the first connecting pipe 1-6-3 is connected to the crushing device 3.

[0039] Large pieces of excrement and straw enter the first connecting pipe 1-6-3 through the outlet 1-6-1 and are then discharged together with the solid matter separated by the separation device 2.

[0040] Among them, such as Figure 1-11 As shown, the separation device 2 includes a separation cylinder 2-1, a second connecting pipe 2-2, a separation chamber 2-3, a conical ring plate 2-4, and a separation mechanism 2-5.

Water is provided inside the separation chamber 2-3.

[0041] The conical ring plate 2-4 causes the mixture of excrement and water to concentrate towards the separation mechanism 2-5, which then separates the solid matter from the mixture and discharges it into the separation cylinder 2-1. The remaining liquid mixture can then be used for irrigation.

[0042] Among them, such as Figure 1-11 As shown, the separation mechanism 2-5 includes a rotating shaft 2-5-1, a fixed cylinder 2-5-2, an inlet 2-5-3, a spiral plate 2-5-4, a drain hole 2-5-5, an outlet pipe 2-5-6, and a conical top 2-5-7. The rotating shaft 2-5-1 is mounted on the separation cylinder 2-1, and the fixed cylinder 2-5-2 is located inside the separation cylinder 2-1. The fixed cylinder 2-5-2 has an inlet 2-5-3 and a drain hole 2-5-5. The spiral plate 2-5-4 is mounted on the rotating shaft 2-5-1 and rotates inside the fixed cylinder 2-5-2.

[0043] The rotating shaft 2-5-1 drives the spiral plate 2-5-4 to rotate, pushing the mixture of solid and water into the fixed cylinder 2-5-2. Under the pressure of the spiral plate 2-5-4, the liquid flows from the drain hole 2-5-5 into the separation chamber 2-3, and then the solid is discharged through the outlet pipe 2-5-6. The rotating conical top 2-5-7 prevents the excrement from accumulating on the fixed cylinder 2-5-2.

The first extrusion shaft 3-3-1 is connected to the cutting device 3-4 via the second transmission belt 3-3-7.

[0047] The first extrusion shaft 3-3-1 drives the second extrusion shaft 3-3-3 to rotate via the second gear 3-3-2 and the third gear 3-3-4. The second extrusion shaft 3-3-3 and the first extrusion shaft 3-3-1 rotate in opposite directions. The first extrusion shaft 3-3-1 and the second extrusion shaft 3-3-3 drive the rolling wheel 3-3-5 to rotate to extrude straw and large pieces of excrement.
