Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation beds, and in particular relates to a turning and raking device suitable for fermentation beds of dry toilets. Background Art

[0002] Fermentation bed technology uses microbial complex fermentation to directly convert the feces and urine produced by livestock and poultry and their living bedding from unstable organic matter that is difficult to directly use into usable stable organic matter, thereby controlling livestock and poultry breeding pollution, utilizing feces and sewage as resources, and realizing an environmentally friendly and pollution-free ecological breeding method. Microbial fermentation bed technology has also gradually begun to be applied in the renovation of rural toilets in mountainous areas. It not only solves the problem caused by the lack of water resources in toilet renovation, but also reduces costs, and also realizes the resource utilization of feces and sewage. However, the long-term and stable function of the fermentation bed requires regular turning and raking to ensure that aerobic bacteria can obtain sufficient oxygen for fermentation. Otherwise, when the fermentation bed does not contain enough oxygen, the strain will die due to lack of oxygen, causing the fermentation bed to become a dead bed. Therefore, a turning and raking machine suitable for rural dry toilet fermentation beds is essential.

[0003] At present, there are various types of multifunctional fermentation bed turning machines on the market, but they are all developed to meet the needs of isotopic fermentation beds and exotopic fermentation beds in the aquaculture industry. For dry toilet fermentation beds, the operation is complicated, the project volume is large, and the cost is high, and they are not suitable for use in dry toilet fermentation beds. Summary of the invention

[0004] The utility model provides a turning and raking device suitable for a dry toilet fermentation bed, which has a simple structure, is easy to operate, and has a low manufacturing cost. It can effectively mix the fermentation bedding material and excrement evenly to ensure that aerobic bacteria obtain sufficient oxygen. The specific scheme is as follows:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-7 A raking device suitable for a fermentation bed in a dry toilet comprises a box body 1 and a box cover hingedly connected to the box body 1. A rotating shaft 2 is horizontally rotatably arranged between the two side walls of the box body 1. A driving motor 3 is arranged on one side wall of the box body 1. The output shaft of the driving motor 3 is connected to one end of the rotating shaft 2 through a coupling. A plurality of raking claws 4 are arranged at intervals along the axial direction of the rotating shaft 2 in the box body 1. The plurality of raking claws 4 are detachably connected to the rotating shaft 2 through a sleeve. A horizontally displaceable toggle mechanism 5 is arranged between the two raking claws 4. The toggle mechanism 5 is used to toggle the toggle mechanism 5 back and forth when the raking claws 4 rake up the excrement, so as to further ensure that the fermented bedding is mixed with the excrement and ensure that the aerobic bacteria get sufficient oxygen. The driving motor 3 and the raking claw mechanism are both connected to a controller.

[0024] The toggle mechanism 5 includes a circular turntable 51, an electric telescopic rod 52, a displacement rod 53 and a toggle claw 54. The two outer sides of the box body 1 are respectively formed with a cavity 6 by a connecting plate. Circular through holes are opened between the two side walls of the box body 1. Circular turntables 51 are arranged in the two circular through holes. The circular turntables 51 are circumferentially matched with the gaps between the circular through hole walls. The two ends of the rotating shaft 2 respectively penetrate the two circular turntables 51 and are rotatably connected to the connecting plates on both sides. The displacement rod 53 horizontally penetrates a plurality of rake claws 4 and the two circular turntables 51, and its two ends extend to the outside of the circular turntable 51 respectively. The displacement rod 53 between the two rake claws 4 can be detachably connected with a toggle claw 54. An electric telescopic rod 52 is arranged on the outside of a circular turntable 51 and its output end It is connected to the displacement rod 53. The setting of the two cavities 6 makes it convenient for one end of the displacement rod 53 and the electric telescopic rod 52 to be placed therein. When in use, the controller controls the driving motor 3 to drive the rotating shaft 2 to rotate, so that the excrement can be flipped into the litter, so that the microorganisms in the litter can fully contact the excrement and increase the oxygen content of the litter. Specifically, the rotating shaft 2 drives the circular turntable 51 to rotate when it rotates. At the same time, the electric telescopic rod 52 drives the displacement rod 53 to do reciprocating motion. When the rotation drives the turning claw 4 to turn the excrement, the electric telescopic rod 53 drives the moving claw 54 to move the turned excrement back and forth, further ensuring that the excrement and the fermented litter are thoroughly mixed, and ensuring that the aerobic bacteria get sufficient oxygen.

[0025] A limit rod 55 is horizontally provided between the two rake claws 4 on one side of the displacement rod 53. Both ends of the limit rod 55 are detachably connected to the rake claws 4. One end of a plurality of moving claws 54 is movably sleeved on the relative limit rod 55. The setting of the limit rod 55 makes it easier to stabilize the moving claws 54 when they make reciprocating motion.

[0026] A limiting ring 56 is disposed around the circular turntable 51 , and a limiting groove suitable for the rotation of the limiting ring 56 is provided inside the circular through hole. The setting of the limiting ring 56 facilitates the stability of the circular turntable 51 during rotation.

[0027] Preferably, a mounting seat 57 is provided on the circular turntable 51 on the side of the electric telescopic rod 52 , and the electric telescopic rod 52 is detachably connected to the mounting seat 57 .
