Description

Technical Field

[0001] The present invention relates to the technical field of manure treatment, and in particular to a device for recycling manure in a breeding farm and a method for recycling manure in a breeding farm. Background Art

[0002] In the field of manure treatment technology, traditional treatment methods for the large amount of livestock and poultry manure generated during agricultural production are often limited to simple stacking, landfilling or direct application to farmland. These methods are not only inefficient, but also may cause environmental pollution, the spread of pathogenic microorganisms and other problems.

[0003] In the process of manure treatment, many problems may occur. If the crushing is not good, there will be large lumps in the manure, which will affect the subsequent links, such as clogging of the vibrating screen and uneven squeezing, which will reduce the overall treatment efficiency. If the vibrating screen is not thorough, solid impurities will remain in the liquid, affecting the separation quality, and may damage the subsequent dehydration equipment, increasing the maintenance cost.

[0004] The dehydration effect is not obvious, and the water content of manure is still high, resulting in excessive volume and weight, increasing the difficulty of transportation and storage, and is not conducive to its reuse as fertilizer or other resources.

The small-diameter linkage pulley is transmission-connected to the large-diameter driven pulley via a second belt.

[0031] The present invention also proposes a method for utilizing the farm manure recycling device, comprising the following steps:

[0032] Step 1: Under the driving action of the dual-axis motor, the two motor shafts of the dual-axis motor synchronously drive a pair of eccentric cams to rotate, drive the second spring to vibrate through the reinforcement plate, drive the U-shaped plate and the positioning slide rod to slide back and forth along the positioning slide hole, and drive the third spring to vibrate, and then drive the inclined screen plate and a pair of retaining edges to vibrate along the first spring through the positioning connecting plate;

[0033] Step 2: Under the driving action of the servo motor, the motor shaft of the servo motor drives the first horizontal axis, the large diameter gear, the first stirring paddles, the first pulley, and the second pulley to rotate synchronously, and the large diameter gear meshes to drive the widened gear, the second horizontal axis, and the second stirring paddles to rotate in the opposite direction, so that the first stirring paddles and the second stirring paddles rotate relatively;

[0034] Step three, the second pulley drives the third pulley, the fixed coupling shaft, and the second arc-shaped swing arm to rotate through the driving belt, and drives the notched disk and the center shaft to reciprocate under the limiting effect of the second pin shaft and the second arc-shaped groove, and drives the first arc-shaped swing arm, the driven coupling shaft, and the worm to reciprocate under the limiting effect of the first pin shaft and the first arc-shaped groove;

[0035] Step 4: The worm is meshed again to drive the worm wheel, the reciprocating shaft and a pair of reciprocating swing arms to swing back and forth, and under the limiting action formed by a pair of limiting pins and the elliptical pin holes, the rectangular sleeve, a pair of retaining rings and the second transverse axis are driven to slide back and forth, so that the plurality of second stirring paddles are reciprocatingly translated;

[0036] Step 5: The first pulley drives the large-diameter linkage pulley, the linkage shaft, and the small-diameter linkage pulley to rotate at a medium speed through the first belt, and the small-diameter linkage pulley then drives the large-diameter driven pulley, the spiral shaft, and the spiral extrusion blade to rotate at a low speed through the second belt;

[0037] Step 6: The manure enters the elliptical horizontal box through the inverted trapezoidal feed hopper, and the large lumps in the manure are broken up by the coordinated use of a plurality of first stirring paddles and a plurality of second stirring paddles. After being crushed, the manure falls onto the inclined screen plate along the flat discharge hole;

[0038] Since the inclined screen plate is in a state of continuous vibration, part of the liquid in the manure falls through the screen holes into the trapezoidal open box, and the manure slides along the inclined screen plate into the U-shaped box;

[0039] Then, through the spiral extrusion effect of the spiral shaft and the spiral extrusion blades, the feces and sewage are pushed along the spiral extrusion blades toward the conical die, and a small amount of liquid in the feces and sewage falls into the trapezoidal open box along the extrusion hole. The liquid in the trapezoidal open box is finally discharged through the sewage pipe;

[0040] The feces and sewage enter the conical mold. Since the feces and sewage are in an extruded state, they are driven along the internal aperture of the conical mold to push the extrusion end, conical baffle, rectangular baffle and T-shaped slide bar to slide outward along the limiting slide hole. The dehydrated feces and sewage fall to the bottom along the gap between the extrusion end and the conical mold, thus completing the feces and sewage dehydration process.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. In the present invention, by using the vibrating sieve mechanism in combination, better graded separation can be achieved according to the characteristics of feces and sewage, so that the separation of liquid and solid is more orderly, thereby improving the separation quality and obtaining cleaner feces and sewage liquid for subsequent treatment. For feces and sewage of different components and consistencies, the vibrating sieve mechanism can better adapt to the mode of driving the inclined sieve plate to vibrate, which not only improves the continuous operation time of the equipment, but also reduces the labor intensity and maintenance cost of manually cleaning the sieve plate;

[0043] 2. In the present invention, by using the stirring mechanism in coordination, the first stirring paddles and the second stirring paddles rotate relative to each other and move back and forth, so that the feces can be processed in all directions in the elliptical horizontal box, and both the central part and the edge part of the feces can be uniformly stirred and crushed, which helps to make the size of the crushed feces particles more uniform;

[0044] 3. In the present invention, the degree of dehydration can be controlled by adjusting the parameters such as the rotation speed of the spiral shaft and the spacing of the spiral extrusion blades through the spiral extrusion mechanism, so that water can be separated from feces and sewage relatively purely; the structure of the spiral extrusion mechanism is relatively simple, mainly consisting of components such as the spiral shaft, the spiral extrusion blades and the conical mold, and it is not easy to have complex faults during long-term operation, thereby ensuring the purity of the dehydrated feces and sewage and the separated water;

[0045] In summary, the dehydration effect of manure after crushing, vibrating and extruding in the present invention is remarkable. Crushing makes the manure particles smaller, which is beneficial to subsequent processing, vibrating realizes the preliminary separation of solid and liquid, and extruding further removes water. After dehydration, the volume and weight of manure can be reduced, which is convenient for transportation and storage. The separated water can be processed and reused, and the solid can be used as a high-quality fertilizer raw material. BRIEF DESCRIPTION OF THE DRAWINGS

It can also draw the feces and dirt located at the edge or corner of the elliptical horizontal box 3 into the central area of ​​stirring, so that the feces and dirt that may have been missed can also be fully crushed.

[0080] Embodiment 4: Based on Embodiment 3, this embodiment further includes:

[0081] In the specific implementation process, Figure 8 and Fig. 9 As shown, the spiral extrusion mechanism includes a spiral shaft 63 and a spiral extrusion blade 64. A suspended rectangular baffle 65 is provided on the outer side of the conical die 62. A conical baffle 66 is fixedly provided in the middle of the inner side of the rectangular baffle 65. An extrusion end 67 is fixedly provided in the middle of the inner side of the conical baffle 66. Fixed sliding holes are opened in the middle of the rectangular baffle 65, the conical baffle 66 and the extrusion end 67.

[0082] A concentrically distributed spiral shaft 63 is provided in the U-shaped box 6. The right end of the spiral shaft 63 rotates to penetrate the right side wall of the trapezoidal open box 1 and extends to the outside. The left end of the spiral shaft 63 penetrates the conical mold 62 and is slidably inserted in the fixed sliding hole. A plurality of spiral extrusion blades 64 distributed in a continuous spiral shape are fixed on the spiral shaft 63. The left section of the spiral extrusion blade 64 is conical to fit the conical mold 62. Through the spiral extrusion effect of the spiral shaft 63 and the spiral extrusion blade 64, the feces and sewage are driven along the spiral extrusion blade 64 toward the conical mold 62.

[0083] The four corners of the outer side of the conical mold 62 are provided with limited sliding holes, and a T-shaped sliding rod 68 is slidably inserted in the interior of each limited sliding hole. The left end of each T-shaped sliding rod 68 is fixedly connected to the corner of the rectangular baffle 65, and the right section of each T-shaped sliding rod 68 is sleeved with a fourth spring 69. Under the action of the fourth spring 69, the T-shaped sliding rod 68, the rectangular baffle 65, the conical baffle plate 66, and the extrusion end 67 are always driven to slide in the direction of the conical mold 62, and cooperate with the feces and sewage at the spiral extrusion position to complete the feces and sewage dehydration process;

[0084] The right end of the first transverse shaft 35 is sleeved with a first belt pulley and a second belt pulley which are fixedly connected concentrically in sequence, and the outer end of the fixed connecting shaft 55 is sleeved with a third belt pulley which is fixedly connected concentrically in sequence. The second belt pulley is connected to the third belt pulley through a driving belt 38, and the second belt pulley drives the third belt pulley, the fixed connecting shaft 55, and the second arc-shaped swing arm 56 to rotate through the driving belt 38.

[0085] A linkage shaft 17 is rotatably inserted in the middle of the right side of the trapezoidal open box 1, and a concentrically fixed large-diameter linkage pulley is sleeved in the middle of the linkage shaft 17. The first pulley is connected to the large-diameter linkage pulley through a first belt 18. The first pulley drives the large-diameter linkage pulley, the linkage shaft 17, and the small-diameter linkage pulley to rotate at a medium speed through the first belt 18.

[0086] The right end of the linkage shaft 17 is sleeved with a concentrically fixed small-diameter linkage pulley, and the right end of the spiral shaft 63 is sleeved with a concentrically fixed large-diameter driven pulley. The small-diameter linkage pulley is connected to the large-diameter driven pulley through the second belt 19. The small-diameter linkage pulley then drives the large-diameter driven pulley, the spiral shaft 63, and the spiral extrusion blade 64 to rotate at a low speed through the second belt 19.

[0087] The spiral extrusion mechanism can realize a continuous extrusion and dehydration process. The spiral shaft 63 drives the spiral extrusion blades 64 to push the feces and sewage to move forward continuously. In this process, the feces and sewage are subjected to a gradually increasing extrusion force, just like wringing out a towel, and the water in the feces and sewage is continuously squeezed out.

[0088] The spiral extrusion blade 64 is rotated to apply an extrusion force to the feces, and this extrusion force can penetrate into the feces and effectively squeeze out the moisture therein. Due to the structural characteristics of the spiral extrusion blade 64, the feces can be squeezed from multiple directions, so that the entire feces can be fully squeezed to achieve a better dehydration effect.

[0089] Specifically, the working principle and operation method of the present invention are as follows:

[0090] Step 1: Under the driving action of the dual-axis motor 23, the two motor shafts of the dual-axis motor 23 synchronously drive a pair of eccentric cams 24 to rotate, drive the second spring 27 to vibrate through the reinforcement plate 26, drive the U-shaped plate 22 and the positioning slide rod 28 to slide back and forth along the positioning slide hole, and drive the third spring 29 to vibrate, and then drive the inclined screen plate 11 and a pair of retaining edges 13 to vibrate along the first spring 15 through the positioning connecting plate 25;

[0091] Step 2: Under the driving action of the servo motor 34, the motor shaft of the servo motor 34 drives the first horizontal axis 35, the large diameter gear 37, the first stirring paddles 36 and the first pulley and the second pulley to rotate synchronously, and the large diameter gear 37 meshes to drive the widened gear 42, the second horizontal axis 4, and the second stirring paddles 41 to rotate in the opposite direction, so that the first stirring paddles 36 and the second stirring paddles 41 rotate relatively;

[0092] Step 3: The second pulley drives the third pulley, the fixed connecting shaft 55, and the second arc-shaped swing arm 56 to rotate through the driving belt 38, and drives the notched disk 59 and the central shaft 58 to reciprocate under the limiting effect of the second pin shaft and the second arc-shaped groove, and drives the first arc-shaped swing arm 52, the driven connecting shaft, and the worm 51 to reciprocate under the limiting effect of the first pin shaft and the first arc-shaped groove;

[0093] Step 4: The worm 51 meshes again to drive the worm wheel 48, the reciprocating shaft 47 and the pair of reciprocating swing arms 49 to swing back and forth, and under the limiting action formed by the pair of limiting pins 45 and the elliptical pin holes, the rectangular sleeve 44, the pair of retaining rings 43 and the second horizontal axis 4 are driven to slide back and forth, so that the plurality of second stirring paddles 41 are reciprocatingly translated;

[0094] Step 5: The first pulley drives the large-diameter linkage pulley, the linkage shaft 17, and the small-diameter linkage pulley to rotate at a medium speed through the first belt 18, and the small-diameter linkage pulley then drives the large-diameter driven pulley, the spiral shaft 63, and the spiral extrusion blade 64 to rotate at a low speed through the second belt 19;

[0095] Step 6: The manure enters the elliptical horizontal box 3 through the inverted trapezoidal feed hopper 32, and the large lumps in the manure are broken up by the coordinated use of a plurality of first stirring paddles 36 and a plurality of second stirring paddles 41. After being crushed, the manure falls onto the inclined screen plate 11 along the flat discharge hole 31;

[0096] Since the inclined screen plate 11 is in a continuous vibration state, part of the liquid in the feces and sewage falls into the trapezoidal open box 1 through the screen holes 12, and the feces and sewage slides along the inclined screen plate 11 into the U-shaped box 6;

[0097] Then, through the spiral extrusion effect of the spiral shaft 63 and the spiral extrusion blade 64, the feces and sewage are pushed along the spiral extrusion blade 64 toward the conical die 62, and a small amount of liquid in the feces and sewage falls into the trapezoidal open box 1 along the extrusion hole 61, and the liquid in the trapezoidal open box 1 is finally discharged through the sewage pipe 16;

[0098] The feces and sewage enter the conical mold 62. Since the feces and sewage are in an extruded state, they are driven along the internal aperture of the conical mold 62 to push the extrusion end 67, the conical baffle 66, the rectangular baffle 65 and the T-shaped slide bar 68 to slide outward along the limiting slide hole. The dehydrated feces and sewage fall to the bottom along the gap between the extrusion end 67 and the conical mold 62, thereby completing the feces and sewage dehydration process.

[0099] The dehydration effect of the manure after crushing, vibrating and squeezing in the present invention is remarkable. The crushing makes the manure particles smaller, which is convenient for subsequent treatment, the vibrating realizes the preliminary separation of solid and liquid, and the squeezing further removes water. After dehydration, the volume and weight of the manure can be reduced, which is convenient for transportation and storage. The separated water can be processed and reused, and the solid can be used as a high-quality fertilizer raw material.

[0100] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
