Description

Technical Field

[0001] The invention relates to the technical field of solid excrement treatment, in particular to a pulverizing device for excrement fermentation in livestock farms. Background Art

[0002] Livestock manure fermentation first removes excess moisture from the livestock manure by drying or heating it to avoid hypoxia during the fermentation process caused by excessive moisture in the livestock manure. Then, sawdust, straw, stalks and other auxiliary materials are mixed into the livestock manure, and finally the livestock manure is piled up for fermentation.

[0003] After removing excess water from livestock manure, the livestock manure tends to clump, which will cause uneven contact with air during the fermentation process, reducing the activity space of microorganisms. The agglomeration of livestock manure will also make ammonia difficult to volatilize. The ammonia will accumulate in the livestock manure, inhibiting the activity of beneficial microorganisms and may even lead to the interruption or failure of livestock manure fermentation.

[0004] Before mixing livestock manure with auxiliary materials, the prior art mostly uses a rotating crushing blade in a crushing machine to crush the livestock manure. However, livestock manure is easily adhered to the crushing blade and the inner wall of the shell, and workers are required to clean the adhered livestock manure, which affects the crushing efficiency of the livestock manure.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1-5 The present embodiment discloses a pulverizing device for livestock farm manure fermentation, comprising a shell 1 with openings at both the top and the bottom, a plurality of pulverizing assemblies 9 are arranged in the inner cavity of the shell 1 along the vertical direction, the pulverizing assembly 9 comprises a first round shell 91 and a second round shell 92, the bottom end of the first round shell 91 and the top end of the second round shell 92 are slidably fitted, the outer circumference of the first round shell 91 and the inner wall of the shell 1 are connected by bolts or buckles, the outer circumference of the second round shell 92 and the inner wall of the shell 1 are connected by bearings, a plurality of second rope bodies 96 are fixed at equal intervals on the top of the inner wall of the second round shell 92, and a plurality of first rope bodies 94 are fixed at equal intervals on the bottom of the inner wall of the first round shell 91.

[0036] The housing 1 is provided with a power assembly for driving the second round shell 92 to rotate.

[0037] The vertical distance between the first rope body 94 and the second rope body 96 is 0-2.0 mm.

[0038] Furthermore, the first rope body 94 is a steel wire or an iron wire, and the second rope body 96 is a steel wire or an iron wire.

[0039] The working process and principle of this embodiment are:

[0040] External conveying equipment or workers add livestock manure into the opening at the top of the shell 1, and then the livestock manure falls on the first rope body 94 in the first round shell 91, the power component drives the second round shell 92 to rotate, and the second round shell 92 drives the second rope body 96 to rotate, and the angle between the first rope body 94 and the second rope body 96 projected on the horizontal plane is constantly changing, the first rope body 94 and the second rope body 96 continuously clamp the livestock manure to crush the livestock manure, and the second rope body 96 and the first rope body 94 are constantly staggered to make the livestock manure adhered to the first rope body 94 and the second rope body 96 fall off, thereby reducing the workload of workers cleaning the crushing component 9 and improving the crushing efficiency of livestock manure.

[0041] Furthermore, workers add fermentation bacteria when the livestock manure enters the opening at the top of the shell 1, so as to achieve mixing of the livestock manure and the fermentation bacteria.

[0042] Embodiment 2:

[0043] like Figure 6 As shown, this embodiment discloses a pulverizing device for livestock farm manure fermentation, and its structure is substantially the same as that of the first embodiment, except that a plurality of cutting teeth are provided on the first rope body 94 and the second rope body 96 of this embodiment.

[0044] The working process and principle of this embodiment are:

[0045] When the livestock manure is chicken manure, the chicken manure contains chicken feathers that fall from the chickens. The chicken feathers are not easy to decompose during the fermentation process of the chicken manure, which hinders the activity of microorganisms, affects the decomposition rate of organic matter in the chicken manure, and reduces the overall fermentation efficiency of the chicken manure. Existing crushing machines mostly use impact to crush chicken manure, which has a poor effect on crushing chicken feathers.

[0046] The power assembly drives the second round shell 92 to rotate, and the second round shell 92 drives the second rope body 96 to rotate. The angle between the first rope body 94 and the second rope body 96 projected on the horizontal plane keeps changing. The chicken feathers are clamped by the first rope body 94 and the second rope body 96 as they move downward with the chicken manure, and the chicken feathers slide along the first rope body 94 or the second rope body 96. The chicken feathers are cut by the cutting teeth during the sliding process, thereby crushing the chicken feathers and reducing the influence of the chicken feathers on the fermentation of chicken manure.

[0047] Embodiment three:

[0049] The working process and principle of this embodiment are:

[0050] The power assembly drives the second round shell 92 to rotate, and the second rope body 96 is constantly in contact with the spherical body 95. The spherical body 95 pushes the chicken feathers wrapped on the first rope body 94 to move along the first rope body 94. At the same time, the spherical body 95 pushes the chicken feathers wrapped on the second rope body 96 to move along the second rope body 96. The chicken feathers wrapped on the first rope body 94 and the chicken feathers wrapped on the second rope body 96 are cut by the cutting teeth, so as to prevent the chicken feathers wrapped on the first rope body 94 from affecting the chicken manure from falling downward through the gap of the first rope body 94, thereby improving the reliability of the crushing device for manure fermentation in livestock farms.

[0051] Furthermore, the ball 95 is made of metal or hard plastic.
