Description

Technical Field

[0001] The invention relates to a device for removing feces and urine, and in particular to a step-by-step automatic feces scraping system for a pig house. Background Art

[0002] Manure cleaning is one of the important tasks in pig farming. The choice of manure cleaning method not only affects the labor cost of the pig farm and the cleanliness and sanitation of the pig house, but is also closely related to the treatment and utilization of manure in the pig farm. At present, with the rising labor cost of pig farms and the high difficulty and cost of sewage treatment, mechanical scraper manure cleaning has gradually been adopted by modern large-scale pig farms due to its advantages such as saving labor, reducing water consumption and sewage generation.

[0003] (1) Poor stability. Currently, most pig farms install position switches at multiple locations in the manure ditch, such as the parking position, pause position, and end position, where the scraper passes during its travel. These switches are used to control the start, stop, and turn of the mechanical scraper at different locations. Multiple position switches require a corresponding number of lines to be arranged in the manure ditch for connection. The rats in the pig farm and the corrosive environment such as feces and ammonia in the manure ditch cause great damage to the lines, resulting in frequent failures of the manure cleaning system, affecting normal pig production.

[0004] (2) The failure rate is high. Most of the existing manure scrapers on the market use steel wire ropes or linen ropes for traction. Since the manure in the manure ditch is not evenly distributed, the manure scraper is prone to tilt during movement, causing damage to the manure scraper; when there is a lot of manure in the manure ditch, the tail of the manure scraper will lift up, resulting in incomplete manure cleaning and affecting the air quality in the house. Steel wire ropes are prone to breakage during long-term use, and their maximum service life is less than two years. Linen ropes also need to be tightened regularly during use, which results in a large amount of maintenance and regular replacement of traction-type manure scrapers during use, causing great trouble to the production process. Summary of the invention

[0005] In order to solve the technical problems of short service life and high failure rate of manure scraping device, the present invention provides a step-by-step automatic manure scraping system for a pig house, comprising a driving system, a scraper assembly and a transmission rod, wherein the driving system drives the transmission rod to reciprocate, and is characterized in that a row of jacks are arranged on the transmission rod at equal intervals, a machine head is arranged on the scraper assembly, the transmission rod passes through the machine head, a steering key and a steering lever are arranged on the machine head, the middle part of the steering key is rotatably connected to the machine head, and both ends of the steering key are pointed ends. During the operation of the scraper assembly, one side of the steering key is always tilted under the action of gravity, and the tip on the other side is periodically inserted into the jack as the transmission rod reciprocates. During the insertion of the tip into the jack, the scraper assembly moves with the transmission rod, one end of the steering lever is rotatably connected to the steering key, and steering push rods are arranged at both ends of the transmission rod. When the scraper assembly moves to the extreme positions at both ends of the transmission rod, the steering push rod controls the steering lever to drive the other side of the steering key to tilt.

[0006] In order to facilitate automatic steering by turning the steering key, the middle part of the steering key is connected to the machine head through a steering pin, the middle part of the steering lever is connected to the machine head through a lever pin, the lower part of the steering lever is a ring sleeve, the ring sleeve is mounted on the middle pin shaft of the steering key, and the upper part of the steering lever passes through the machine head.

[0007] In order to improve the running stability and prevent the scraper assembly from tipping over and tilting up, two sets of guide wheels are provided in the machine head, and each set of guide wheels laterally embraces the transmission rod. Two pressure wheels are provided in the machine head, and the pressure wheels press on the transmission rod.

[0008] In order to prevent the steering key from being disengaged due to shaking of the scraper assembly and the transmission rod during operation, the transmission rod is a groove-shaped rigid long axis, the insertion hole is a rectangular opening, and the cross-section of the tip is a rectangle.

[0009] In order to prevent the steering key from getting stuck due to shaking of the scraper assembly and the transmission rod during operation, positioning shafts are provided at both ends of the steering key to prevent the body from being stuck by the rectangular hole on the transmission rod.

[0010] In order to facilitate transmission, the driving system is rotationally connected to a crank, the crank is rotationally connected to a connecting rod, and the connecting rod is rotationally connected to the transmission rod.

[0011] In order to prevent the transmission rod from tilting and warping, two driving end transmission rod supports are provided at one end of the transmission rod close to the driving system, the connection point between the connecting rod and the transmission rod is located between the two driving end transmission rod supports, and a plurality of in-ditch transmission rod supports are provided at the bottom of the transmission rod, and the transmission rod reciprocates on the driving end transmission rod supports and the in-ditch transmission rod supports.

[0012] Preferably, the drive end transmission rod support includes a bracket, a lateral pin, an upper pressure wheel, a pressure wheel fixing pin and a supporting wheel, the transmission rod is located between the upper pressure wheel and the supporting wheel, both ends of the upper pressure wheel are connected to the bracket through the pressure wheel fixing pin, the left and right sides of the transmission rod are constrained by the lateral pin, the lateral pin is rotatably connected to the bracket, and the lateral pin is used to constrain the running direction of the transmission rod.

[0013] Preferably, the transmission rod support in the manure ditch includes a T-shaped base and a pulley, the pulley is connected to the T-shaped base through a pin shaft, and the transmission rod is located on the pulley.

[0014] The present invention has the following beneficial effects:

[0015] 1. Low failure rate: During operation, the steering key will remain tilted in the same direction under the action of gravity, so as to keep the scraper assembly running forward or backward. When the scraper assembly runs to the end of the manure ditch, the steering push rod on the transmission rod will push the steering lever to rotate, thereby driving the steering key to turn, so that the manure scraper can automatically reverse. The transmission rod moves forward: the socket pushes the scraper assembly to move in the same direction as the transmission rod; the transmission rod moves in the opposite direction: the socket is disengaged from the tip, the scraper assembly is stationary, and the scraper assembly follows the transmission rod to make periodic movements. The scraper assembly runs in a step-by-step manner. When the scraper assembly runs to the ends of the manure ditch, it can switch the running direction by itself, so as to realize the automatic reciprocating operation of the step-by-step automatic manure scraping system. During this process, the direction of the motor remains unchanged. The overall structural strength of the scraper assembly is high and more durable. Compared with the traditional steering mechanism using springs, it has a short service life and a high failure rate. The automatic steering structure designed in the present invention overcomes this shortcoming, improves the reliability of the manure cleaning system, and effectively reduces the failure rate.

[0016] 2. Good stability: The transmission rod acts as a transmission part to drive the scraper assembly forward or backward, and also acts as a track to constrain the running direction of the scraper device, so that the scraper device will not tilt during operation, reducing the failure rate; through the constraints of the transmission rod by the machine head, the driving end transmission rod support and the transmission rod support in the manure ditch, the scraper assembly will not tilt or warp during operation, thereby improving the cleanliness of manure cleaning.

[0032] Example 1

[0033] like Figure 1-13 As shown, a step-by-step automatic manure scraping system for a pig house comprises a driving system 1, a crank 1-2, a connecting rod 1-3, a scraper assembly 2 and a transmission rod 3. The driving system 1 comprises a motor 1-1, a motor fixing seat 1-4 and a reducer. The motor 1-1 is rotatably connected to the crank 1-2, the crank 1-2 is rotatably connected to the connecting rod 1-3, the connecting rod 1-3 is rotatably connected to the transmission rod 3, the connecting rod 1-3 drives the transmission rod 3 to reciprocate, and a row of jacks 3-2 are evenly spaced on the transmission rod 3. The scraper assembly 2 is provided with a machine head 2-3, two side scrapers 2-1, a main scraper 2-2 and a reinforcement beam 2-4. The machine head 2-3 is located in the middle of the scraper assembly 2, and the reinforcement beam 2-4 connects the machine head 2-3, the side scrapers 2-1 and the main scraper 2-2 as a whole. The transmission rod 3 runs through the machine head 2-3. A steering key 2-3-3 and a steering lever 2-3-5 are provided, the middle part of the steering key 2-3-3 is rotatably connected to the machine head 2-3, and both ends of the steering key 2-3-3 are pointed ends. During the operation of the scraper assembly 2, the steering key 2-3-3 is always tilted on one side under the action of gravity, and the pointed end on the other side is periodically inserted into the socket 3-2 with the reciprocating motion of the transmission rod 3. During the insertion of the pointed end into the socket 3-2, the scraper assembly 2 moves following the transmission rod 3, and one end of the steering lever 2-3-5 is rotatably connected to the steering key 2-3-3. Steering push rods 3-1 are provided at both ends of the transmission rod 3. When the scraper assembly 2 moves to the extreme positions at both ends of the transmission rod 3, the steering push rod 3-1 controls the center of gravity of the steering lever 2-3-5 to move eccentrically, thereby driving the other side of the steering key 2-3-3 to tilt.

[0034] The middle part of the steering key 2-3-3 is connected to the machine head 2-3 through the steering pin 2-3-4, the middle part of the steering lever 2-3-5 is connected to the machine head 2-3 through the lever pin 2-3-6, the lower part of the steering lever 2-3-5 is a ring sleeve, the ring sleeve is arranged on the middle pin 2-3-3-3 of the steering key 2-3-3, and the upper part of the steering lever 2-3-5 passes through the machine head 2-3.

[0035] Two groups of guide wheels 2-3-1 are arranged in the machine head 2-3, and each group of guide wheels 2-3-1 embraces the transmission rod 3 laterally. Two pressure wheels 2-3-2 are arranged in the machine head 2-3, and the pressure wheels 2-3-2 are pressed on the transmission rod 3.

[0036] The transmission rod 3 is a groove-shaped rigid long axis, the insertion hole 3-2 is a rectangular opening, the cross-section of the tip is rectangular, and positioning shafts 2-3-3-2 are provided at both ends of the steering key 2-3-3, so that the scraper assembly 2 and the transmission rod 3 will not cause the steering key 2-3-3 to be disengaged due to shaking during operation. The positioning shaft 2-3-3-2 is welded to the key body 2-3-3-1 of the steering key 2-3-3, and plays a limiting role when the two ends of the key body 2-3-3-1 are inserted into the rectangular holes on the transmission rod 3, thereby preventing the key body 2-3-3-1 from being stuck by the rectangular holes on the transmission rod 3.

[0037] The transmission rod 3 is provided with two driving end transmission rod supports 4 at one end close to the driving system 1, and the connection point between the connecting rod 1-3 and the transmission rod 3 is located between the two driving end transmission rod supports 4. A plurality of manure ditch transmission rod supports 5 are provided at equal intervals at the bottom of the transmission rod 3, and the transmission rod 3 reciprocates on the driving end transmission rod supports 4 and the manure ditch transmission rod supports 5.

[0038] The driving end transmission rod support 4 includes a bracket 4-1, a lateral pin 4-2, an upper pressure wheel 4-3, a pressure wheel fixing pin 4-4 and a supporting wheel 4-5. The transmission rod 3 is located between the upper pressure wheel 4-3 and the supporting wheel 4-5. Both ends of the upper pressure wheel 4-3 are connected to the bracket 4-1 through the pressure wheel fixing pin 4-4. The supporting wheel 4-5 plays a supporting role and can also reduce the running resistance of the transmission rod 3. The left and right sides of the transmission rod 3 are constrained by the lateral pin 4-2, and the lateral pin 4-2 is rotatably connected to the bracket 4-1.

[0039] The transmission rod support 5 in the manure ditch includes a T-shaped base 5-1 and a pulley 5-3. The pulley 5-3 is connected to the T-shaped base 5-1 through a pin 5-2. The transmission rod 3 is located on the pulley 5-3, so that the transmission rod 3 can roll thereon to reduce running resistance.

[0040] The steering key 2-3-3 is a symmetrical structure as a whole, and its supporting point is located on the vertical line of the center of gravity. During the forward stroke operation of the scraper assembly 2, the steering key 2-3-3 deflects to one side. When the transmission rod 3 is in the forward stroke operation, the steering key 2-3-3 is inserted into the rectangular hole on the transmission rod 3, driving the scraper assembly 2 to operate in the forward stroke; when the transmission rod 3 is in the return stroke operation, the steering key 2-3-3 escapes from the rectangular hole on the transmission rod 3, but due to the effect of gravity, the steering key 2-3-3 will not deflect, and the scraper assembly 2 stops running at this time. When the transmission rod 3 starts the forward stroke operation of the next operating cycle, the steering key 2-3-3 is inserted into the next rectangular hole on the transmission rod 3, thereby keeping the running direction of the scraper assembly 2 unchanged and realizing step-by-step operation.

[0041] During the forward stroke operation of the scraper assembly 2, the manure in the primary manure ditch inside the shed is scraped into the secondary manure ditch outside the shed. When the scraper assembly 2 runs to the end of the primary manure ditch, the steering push rod 3-1 on the transmission rod 3 pushes the steering lever 2-3-5, and drives the steering key 2-3-3 to achieve steering, and finally realizes the reverse operation of the scraper assembly 2.
