In this embodiment, the conveyor belts 3 of the conveyors are horizontally arranged, and the height of the conveyor at the front position is lower than the height of the conveyor at the rear position in the same layer of conveying mechanism. In the same layer of conveying mechanism, the conveying speed of the conveyor at the front position is higher than that of the conveyor at the rear position.
In this embodiment, the conveying speed of the conveying belt of each conveyor is related to the weight of the excrement on the conveying belt, if the water content in the excrement is large, the weight of the excrement is large, the conveying speed of the conveying belt of the corresponding conveyor is relatively low, and if the water content in the excrement is small, the weight of the excrement is small, and the conveying speed of the conveying belt of the corresponding conveyor is high. The specific speed control is realized by the following structure.
The front conveying roller and the rear conveying roller of each conveyor are coaxially fixed to the corresponding roller shafts, respectively, the roller shaft coaxially fixed to the rear conveying roller may be referred to as a rear roller shaft, and the roller shaft coaxially fixed to the front conveying roller may be referred to as a front roller shaft 23. Two ends of the roll shaft penetrate through the left side box wall and the right side box wall respectively, the two ends of the roll shaft are mounted on bearing supports 26 through bearings, roll shaft reset springs 27 with axes extending in the up-down direction are arranged between the equipment box body and the corresponding bearing supports, and the roll shaft reset springs 27 are compression springs.

The corrugated plate 24 can adapt to the up-and-down floating of the roll shaft on one hand, and can avoid excessive loss of hot air on the other hand.
The front side roller shaft is fixed with roller bevel gear 28 in one end, be equipped with the transmission bevel gear 29 with roller bevel gear interlock transmission through transmission shaft 30 rotation on the bearing support 26 that corresponds with roller bevel gear, the axis of transmission bevel gear 29 extends along upper and lower direction setting, driving motor's motor shaft constitutes the drive shaft 34 that the axis extends along upper and lower direction, pass through friction clutch transmission connection between transmission shaft 30 upper end and the drive shaft 34 lower extreme, friction clutch includes the upside friction drive disk 33 with drive shaft lower extreme fixed connection and the downside friction drive disk 31 with transmission shaft upper end fixed connection, downside friction drive disk's upper end is fixed with up end and upside friction drive disk lower disc face contact complex elasticity friction drive pad 32. The transmission bevel gear of the upper layer conveying mechanism and the transmission bevel gear of the lower layer conveying mechanism are positioned at two opposite sides of the equipment box body.
The specific principle of controlling the speed according to the weight of the excrement on the conveyer belt is as follows: when no excrement exists on the conveying belt, the whole weight of the conveyor is the lightest, at the moment, under the action of the roller shaft reset spring, the compression amount of the elastic friction transmission pad reaches the maximum, that is, the friction force between the elastic friction transmission pad and the upper friction transmission disc is the maximum, the elastic friction transmission pad and the upper friction transmission disc do not slip, the rotation speed of the driving shaft is the same as that of the driving shaft, the driving motor can drive the conveying belt to rotate rapidly, when the excrement exists on the conveying belt, the larger the water content in the excrement is, the heavier the excrement is, the whole weight of the whole conveyor is the heavier, the compression amount of the elastic friction transmission pad is reduced, the friction force between the elastic friction transmission pad and the upper friction transmission disc is reduced, the slip phenomenon occurs between the elastic friction transmission pad and the upper friction transmission disc, the rotation speed of the driving shaft is larger, the larger the rotation speed of the excrement is probably different from the rotation speed of the driving shaft, that is the larger the excrement is, the conveying speed of the conveying belt is slow, and the long enough drying effect of the excrement on the conveying belt is ensured. The lower the water content of the excrement is, the lower the weight of the excrement is, and the lower the overall weight of the corresponding conveyor is, so that the conveying speed of the conveying belt is higher, the excrement can be prevented from being dried for too long, the water content is too low, and the drying treatment efficiency can be effectively improved.
Of course, the elasticity of the roll shaft reset spring can ensure that the upper end of the elastic friction transmission pad still keeps contact with the upper friction transmission disc when the front roll shaft is at the bottommost position, and the elastic friction transmission pad and the upper friction transmission disc always keep a transmission relation, but the transmission speed ratio between the driving shaft and the transmission shaft is different.
The bottom wall of equipment box is including being located fly leaf 15 of discharge gate rear side, and the front end of fly leaf 15 links to each other with the discharge gate is articulated, and the articulated axis of fly leaf 15 extends along controlling the direction and sets up, and the fly leaf extends downwards gradually from the back to the front, is fixed with the fixed plate 14 that is located the fly leaf downside on the discharge hopper, is provided with fly leaf floating spring 16 between fixed plate 14 and the fly leaf 15, is fixed with vibrating motor 17 on the fly leaf 15, and the fly leaf is used for accepting the excrement and urine that falls down between two adjacent conveyors of downside one deck conveying mechanism. The vibrating motor is fixed at the rear end of the movable plate.
After the excrement falls on the movable plate, the excrement on the movable plate can be vibrated to the discharge hole from back to front by utilizing the vibration of the vibration motor.
According to the invention, animal manure can be subjected to high-efficiency drying treatment, sheep manure eggs are taken as an example, the sheep manure eggs are conveyed to a conveyor at the left upper corner through a feed inlet and then conveyed from back to front by the conveyor, wet sheep manure eggs are thrown to a conveyor at the front of the same layer, and dry sheep manure eggs are thrown to a conveyor at the next layer, so that part of sheep manure eggs are conveyed from back to front along the same layer conveying mechanism, part of sheep manure eggs are conveyed from back to front towards the next layer conveying mechanism, one-time conveying is realized, the sorting of dry and wet manure materials is realized, the dry sheep manure eggs can be conveyed towards a discharge outlet quickly, the efficiency is ensured, and the drying of the sheep manure eggs is avoided; the wet sheep manure eggs can have sufficient contact time with hot air, so that the drying effect is ensured.
In other embodiments of the invention: the conveying speeds of the conveying belts of the conveyors can be different, and the conveying speeds of the conveying belts can be controlled without a friction clutch, for example, the controller is used for controlling the rotating speeds of the driving motors corresponding to the conveyors; of course, the conveying speeds of the conveying belts of the conveyers of the same layer of conveying mechanism can be the same.
Example 2 of a drying apparatus for pre-fermentation drying of animal manure in an animal farm is shown in fig. 5:
example 2 differs from example 1 in that: in this embodiment, the conveyor belts 3 of the conveyors are gradually inclined upward from the rear to the front, and in the same layer of conveying mechanism, the rear conveying roller 7 of the conveyor positioned at the front is at the same height as the rear conveying roller of the conveyor positioned at the rear, and the front conveying roller 8 of the conveyor positioned at the front is at the same height as the front conveying roller of the conveyor positioned at the rear. In this embodiment, because the excrement is conveyed from bottom to top, the first movement track 18 and the second movement track have a certain change, so that the distance between the adjacent conveyors in the front-rear direction can be more compact, and in order to ensure that the sheep excrement eggs can be conveyed smoothly upwards, a scraping plate can be arranged on the conveying belt.
