Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry, in particular to a monitoring and collecting device for cow urine in a breeding farm. Background Art

[0002] In the process of cattle breeding, it is usually necessary to monitor their health status. By collecting cow urine and analyzing its components, it is helpful to understand the health status of the cattle. At the same time, monitoring the cow's urination time, urination frequency, and urine volume can provide sample data for research work, which is convenient for better research on the habits of cattle.

[0003] Farms of a certain scale use rows of pens to raise cattle. The heads and tails of the cattle in a row of pens are in the same direction, and the heads of the cattle are tied to the fence with ropes, so that each cow has an independent space for activities. There is a manure ditch dug under the pens, and a slatted plate is installed on the manure ditch. The excrement of the cattle is leaked into the manure ditch below through the long slatted grooves on the slatted plate to keep the cowshed clean.

[0004] When collecting cow urine, in addition to the fact that the cow's urination time is uncertain, the collected cow urine must not be mixed with cow feces, which will affect the purity of the cow urine and the urine volume monitoring results.

[0005] In addition, when monitoring and collecting cow urine, cows are always in a state of daily activities, urinating at different points, and the range of the four feet is also wide.

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0063] Example 1; Reference Figure 1-Figure 12 A urine monitoring and collecting device for cattle in a breeding farm comprises: a urine collecting cover 1, a transfer module 2, a urine discharge tube 3 and a urine pump 4; the urine collecting cover 1 comprises a fixing belt 13, and the fixing belt 13 fixes the urine collecting cover 1 to the urination part of the cattle;

[0064] The transfer module 2 includes a urine volume detection module, a urination sensing module 22 and a housing 23, wherein the urine volume detection module and the urination sensing module 22 are both arranged inside the housing 23;

[0065] The housing 23 further comprises a baffle 24, which is disposed at an end of the housing 23, and protrudes from the circumferential range of the housing 23 in the circumferential direction of the housing 23;

[0066] The urine discharge pipe 3 is connected to the urine collecting cover 1 and the housing 23 to discharge the cow urine in the urine collecting cover 1 into the urine volume detection module;

[0067] The liquid inlet end of the urine pump 4 is connected to the urine volume detection module to extract the cow urine in the urine volume detection module.

[0068] The cows are always moving in the cowshed of the farm. If an open container is placed directly under the cow's body to collect the cow urine, it is easy to mix with the cow dung excreted by the cow, and pure cow urine cannot be obtained. The open container is placed above the pen and is easy to be trampled by the cow's hooves. If the urine is collected manually at the side of the cowshed, the number of cows that one person is responsible for is limited, the labor cost is high, and there is also the problem of missed urine collection. The existing method is difficult to monitor and collect cow urine for 24 hours or even longer.

[0069] In the technical solution provided by the present invention, the transfer module 2 is inserted into the long groove of the existing slatted plate 5 in the cowshed, and is located at the lower end of the entire cowshed. After urinating, the cow directly introduces the urine discharged once into the transfer module 2 below. After the urine volume of a single urination is detected in the transfer module 2, it is pumped into a centralized collection container through the urine pump 4. The transfer module 2 only contains the cow urine discharged once by the cow, and will not be full. The transfer module 2 set under the cowshed does not occupy the normal activity space of the cow, and the urination pipe 3 extending below the slatted plate 5 and connected to the transfer module 2 is not placed above the slatted plate 5, so it will not be damaged by being stepped on by the cow's hooves.

[0070] The urine collecting cover 1 is a semi-open cover. After the opening end 11 covers the urination part of the cow, when the cow urinates, all the cow urine is collected in the urine collecting cover 1 to prevent the cow urine from leaking out. The urine collecting cover 1 is provided with a urination port, and the urination tube 3 is connected to the urination port. The fixing belt 13 can be an elastic belt with a certain elasticity to prevent the urine collecting cover 1 from moving after it is fixed on the cow's body. Figure 2 As shown, the fixing belt 13 can be a two-section structure, which is respectively arranged on both sides of the urine collecting cover 1. After the two sections of the fixing belt 1 pass around the cow body, the free ends are connected and fixed by Velcro or buckle. Multiple sets of fixing belts 13 can be used to fix the urine collecting cover 1, such as the two sets shown in the figure.

[0071] In the transfer module 2, the urine volume detection module is used to detect the specific amount of urine excreted by the cow at one time, and the detected data includes one or both of the mass and volume of the cow's urine. The urination sensing module 22 is used to detect whether the cow has urinated, and sends a signal after detecting that the cow has urinated, which serves as a start signal for the urine volume detection module to start detecting urine volume, and a time signal for recording the time of the cow's urination at one time.

[0072] After the urine volume detection module completes the detection, the urine pump 4 is started to pump all the cow urine in the urine volume detection module into the collection container 41. The empty urine volume detection module continues to wait for the next urination and repeats the above actions. A collection container 41 collects the cow urine of a cow during this period of time, so as to facilitate the subsequent detection and analysis of the cow urine.

[0073] A controller can be used to control the urine volume detection module, the urination sensing module 22 and the urine pump 4. The controller receives the signal from the urination sensing module 22, controls the urine volume detection module to detect the urine volume, and then controls the urine pump 4 to pump urine, and records the urination time and urine volume data during this process.

[0074] The transfer module 2 is lowered from the long slot of the slatted plate 5, and the baffle 24 is used to hang the transfer module 2 under the slatted plate 5, so that the transfer module 2 falls into the feces discharge ditch. The urine discharge pipe 3 is pulled up from the bottom of one of the slatted slots 51, passes through the slatted plate 5, and then connected to the urine collecting cover 1.

[0075] The urine pump 4 can be directly arranged on the housing 23, and the urine volume detection module is located below the housing 23. Figure 4 As shown in the figure, the urine pump 4 is arranged outside the cowshed and connected to the urine volume detection module through a pipeline. When the urine pump 4 is not started, the cow urine falling into the urine volume detection module cannot enter the urine pump 4, and the urine volume of one time can be measured in the urine volume detection module. After the urine pump 4 is started, the cow urine is directly emptied for the next use.

[0076] Example 2; Reference Figure 3-Figure 5 Furthermore, the urine collecting cover 1 further comprises a pre-installed snap ring 14, and the shape of the pre-installed snap ring 14 is the same as the shape of the opening end 11 of the urine collecting cover 1;

[0077] The fixing belt 13 is fixedly connected to the side of the pre-installed snap ring 14, and the two ends of the ring of the pre-installed snap ring 14 are respectively a fitting end 141 and a connecting end 142;

[0078] The fitting end 141 is used to fit the skin around the urination part of the cow, and the connecting end 142 is detachably connected to the opening end 11 of the urine collecting cover 1 .

[0079] When the urine collecting cover 1 is fixed on the urination part of the cow, the cover 1 makes it difficult for the staff to observe whether the installation position is correct. At the same time, the urine collecting cover 1 is connected with the urination tube 3, and the urination tube 3 interferes with the flexible adjustment of the position of the urine collecting cover 1.

[0080] By setting the pre-installed snap ring 14, the pre-installed snap ring 14 is small in size and can be quickly fixed around the urination part of the cow, and there is no obstruction inside, which is convenient for the staff to observe the installation position of the pre-installed snap ring 14 and make small adjustments to the installation position to ensure the installation position of the urine collecting cover 1 to avoid urine leakage.

[0081] The fitting end 141 of the pre-installed clamp ring 14 is used to fit the cow's skin to prevent cow urine from leaking from the contact interface. In some embodiments, the fitting end 141 is made of soft material, such as soft glue, foam or air bag, etc., to improve the fit with the cow's skin, further prevent urine leakage, and avoid discomfort caused by hard objects pressing on the cow's body.

[0082] The plug-in end and the open end 11 of the urine collecting cover 1 are detachably connected, and after the pre-installed snap ring 14 is fixed, the urine collecting cover 1 can be installed on the pre-installed snap ring 14. The detachable connection method includes plug-in, bolt fixing, buckle fixing, magnetic fixing and the like.

[0083] Example 3; Reference Figure 3-Figure 5 Furthermore, a card slot 143 is provided on the connection end 142 along the circumference of the pre-installed clamp ring 14, and a connection plug 12 is provided on the circumference of the open end 11, and the connection plug 12 can be plugged and fixed with the card slot 143;

[0084] The pre-installed snap ring 14 and the side of the urine collecting cover 1 are also provided with a fixing snap 15 and a buckle block 153 respectively;

[0085] The fixing buckle 15 can overlap and buckle with the buckle block 153 to prevent the connecting plug 12 from being separated from the slot 143 .

[0086] The plug-in fixing method of the card slot 143 and the connecting plug 12 can enable the urine collecting cover 1 and the pre-installed card ring 14 to be quickly positioned and plugged in. The plug-in method can also limit the position in the circumferential direction to prevent the cow from applying biased force and disengaging when moving.

[0087] The card slot 143 and the connecting plug 12 are both provided with a ring shape in the circumferential direction, which can form a ring-shaped seal when plugged in to avoid urine leakage.

[0088] The card slot 143 is arranged on the pre-installed card ring 14, that is, above it when in use. The connecting plug 12 after being inserted is higher than the joint surface between the card slot 143 and the connecting plug 12, which can prevent cow urine from penetrating into the connecting gap.

[0089] The fixing buckle 15 and the buckle block 153 fix the pre-installed buckle ring 14 and the urine collecting cover 1 after the connecting plug 12 is inserted into the slot, so as to prevent the urine collecting cover 1 from being pulled off when the cow moves. The buckle block 153 has a protruding buckle surface 154 or a hook, a column or other structure, and the fixing buckle 15 has a movable hook portion 151. Rotating or pressing the fixing buckle 15 can make the fixing buckle 15 hook on the buckle block 153 for fixing. Rotating or pressing the fixing buckle 15 again can separate the fixing buckle 15.

[0090] One optional implementation is as follows Figure 6As shown in the figure, the fixing buckle 15 is rotatably connected to the pre-installed buckle 14, the buckle block 153 is fixedly connected to the urine collecting cover 1, and an elastic member 152, such as a spring, is connected to the fixing buckle 15. The elastic member 152 rotates and pushes the hook portion 151 of the fixing buckle 15 toward one end of the buckle block 153. When the urine collecting cover 1 is inserted, the hook portion 151 is hooked on the buckle block 153 to prevent the urine collecting cover 1 from being separated.

[0091] Example 4; Reference Figure 3-Figure 5 Furthermore, a vent hole 16 is provided on the side of the urine collecting cover 1 near the opening end 11 or on the side of the pre-installed snap ring 14;

[0092] It also includes a ventilation hose 161, one end of which is connected to the ventilation hole 16 from the inner side of the urine collecting cover 1 or the pre-installed clamp ring 14;

[0093] A pull-down weight 162 is provided on the circumferential outer side of the other end of the ventilation hose 161 , and the pull-down weight 162 drives the ventilation hose 161 to move downward in the direction of gravity.

[0094] The fitting end 141 is tightly attached to the cow's skin surface to prevent the urine collecting cover 1 from leaking urine. However, when the cow urine is monitored and collected for a long time, the sealed urine collecting cover 1 has no air circulation and is in a humid state. The cow's skin covered by the urine collecting cover 1 is prone to itching and discomfort. At this time, the cow will become irritable, jump violently, or find the fence to rub the covered part, causing the urine collecting cover 1 to fall off, and the cow urine monitoring and collection will be interrupted.

[0095] During urination, negative pressure is easily generated in the sealed space above, which will cause the cow urine to leak downward slowly or even overflow.

[0096] The vent holes 16 can be provided to allow air to circulate inside and outside the urine collecting cover 1, so that the inside of the urine collecting cover 1 remains dry after urination, thereby reducing the impact on the cow after installing the urine collecting cover 1. At the same time, the air pressure inside the urine collecting cover 1 can be balanced to allow the cow's urine to be discharged quickly.

[0097] A ventilation hose 161 and a pull-down weight 162 are provided to extend the ventilation hole 16 to the bottom of the urine collecting cover 1, so as to prevent the cow urine from splashing directly from the open ventilation hole 16 when the cow urinates. When the cow urine is temporarily collected in the urine collecting cover 1, the liquid inlet end of the ventilation hose 161 is lower than the liquid outlet end, so that the cow urine cannot flow out from the ventilation hose 161.

[0098] The weight 162 is pulled down to move the end of the ventilation hose 161 away from the ventilation hole 16 downward in the direction of gravity. When the cow is in an abnormal standing posture, the free end of the ventilation hose 161 is always kept at the bottom of the urine collecting cover 1 to prevent urine leakage.

[0099] Example 5; Reference Figure 7 , Figure 8 , further, the urine volume detection module includes a liquid measuring chamber 211, a float 213 and a displacement sensor 214;

[0100] The float 213 is arranged in the measuring liquid cavity 211, a limiting hole is provided in the middle of the float 213, a guide rod 212 is vertically inserted into the measuring liquid cavity 211, and the float 213 is arranged on the outside of the guide rod 212 through the limiting hole;

[0101] Moreover, there is a sliding gap between the limiting hole and the guide rod 212, so that the float 213 can move up and down along the length direction of the guide rod 212;

[0102] The displacement sensor 214 is disposed at the end of the guide rod 212 to measure the position of the float 213 on the guide rod 212;

[0103] The liquid inlet end of the urine pump 4 is communicated with the bottom of the liquid measuring chamber 211 .

[0104] The volume of the cow urine is detected in the measuring liquid chamber 211. After the cow urine flows into the measuring liquid chamber 211, the float 213 floats on the surface of the cow urine, and then the floating height of the float 213 is detected by the displacement sensor 214. The corresponding values ​​of the height of the float 213 and the page height in the measuring liquid chamber 211 are preset, and the volume of the cow urine can be measured by measuring the height of the float 213.

[0105] The guide rod 212 is used to limit the float 213 from floating in a large range in the circumferential direction in the liquid measuring chamber 211 when the float 213 floats up, so that the float 213 is always in the detection direction of the displacement sensor 214 during the process of floating up and landing.

[0106] The displacement sensor 214 may be a laser displacement sensor 214, such as Figure 8 As shown, the laser displacement sensor 214 will not come into contact with the float 213, and there is no need to use buoyancy to push it.

[0107] In a measurement of the cow urine volume, the displacement sensor 214 can measure the height of the float 213 multiple times within a period of time. When the float 213 is at the same value for multiple consecutive times, the cow urine in the measuring liquid chamber 211 is the total cow urine urinated this time, and the controller records this value as a urination volume.

[0108] Example 6; Reference Figure 7 , Figure 8 Furthermore, the urination sensing module 22 includes a position sensor, which is arranged at the bottom side of the liquid measuring chamber 211 and the measuring direction points to the float 213 . The position sensor is used to detect the position change of the float 213 .

[0109] The position sensor can be a through-beam photoelectric sensor, such as Figure 7As shown, the transmitting end and the receiving end of the beam-type photoelectric sensor are arranged on both sides of the float 213. When the float 213 is at the lowest end, the float 213 is blocked between the transmitting end and the receiving end. When the cow urine enters the measuring liquid chamber 211, the float 213 floats up, and the receiving end receives the light from the transmitting end, and sends a signal of cow urine, so that the urine pump starts to pump urine.

[0110] In some embodiments, before the urine pump starts to pump urine, it can also monitor whether the urine volume has continued to change through the urine volume detection module. When the cow urine no longer increases and the urine volume monitoring module obtains a final urine volume, the urine pump is started to pump urine.

[0111] Alternatively, a push switch 217 is used as a position sensor. When the float 213 is at the bottom, the push switch 217 is pressed. When the float 213 floats up, the push switch 217 pops up, sending a signal of the beef urinating.

[0112] When the float 213 falls, the position sensor can also send a signal indicating that urination is completed, and the controller can control the urine pump 4 to stop pumping urine.

[0113] Example 7; Reference Figure 7-Figure 9 , further, the urine volume detection module also includes a pressure sensor 215, a weighing box 216, a press switch 217 and a reciprocating control component 218;

[0114] The pressure sensor 215 is installed between the liquid measuring chamber 211 and the baffle 24, and the weighing box 216 is installed on the pressure sensor 215, and the weighing box 216 has an opening at one end close to the baffle 24 to allow urine to enter;

[0115] A push switch 217 is provided at the bottom of the weighing box 216. Pressing the push switch 217 can connect the bottom of the weighing box 216 to the outside.

[0116] The reciprocating movement control component 218 is arranged in the pressing direction of the pressing switch 217 and has a function of controlling the movement stroke of the pressing switch 217 .

[0117] The weight of cow urine can be weighed by the pressure sensor 215 and the weighing box 216 to obtain the mass data of cow urine. The pressure sensor 215 is installed between the liquid measuring chamber 211 and the baffle 24, that is, the pressure sensor 215 is installed above the liquid measuring chamber 211 in the use state, and the weighing box 216 is installed above the pressure sensor 215.

[0118] In some embodiments, a funnel 219 may be provided above the weighing box 216. The funnel 219 is fixed inside the shell 23 and is not connected to the weighing box 216. The cow urine from the urination tube 3 is collected and flows into the weighing box 216 through a small opening to prevent the cow urine from spilling.

[0119] After the cow's urine enters the housing 23, it first enters the weighing box 216 for weighing, and then the weighed cow urine is discharged into the liquid measuring chamber 211 below.

[0120] A push switch 217 is provided at the bottom of the weighing box 216 , and when the push switch 217 is pressed, cow urine can leak out from the bottom of the weighing box 216 .

[0121] Specifically, an implementation of the push switch 217 is as follows: Figure 7 , Figure 8 As shown, a hole is opened at the bottom of the weighing box 216, and the push switch 217 includes a plug, a bracket and a spring. The spring is arranged between the bracket and the plug. The spring pushes the plug to block the hole on the weighing box 216. When a reverse force is applied to the push plug, the plug can be separated from the blockage of the hole, allowing the bottom and the outside of the weighing box 216 to be connected.

[0122] The reciprocating motion control component 218 can be an electromagnet, an electric push rod, or a motor that converts rotational motion into linear motion, and any structure that can achieve reciprocating pushing and pulling is acceptable.

[0123] The reciprocating control assembly 218 applies a push or pull force to the pressing plug to move the plug in the opposite direction, such as Figure 8 In one embodiment shown in , an electromagnet with a telescopic push rod is used, which is arranged below the weighing box 216. When moving upward, it can contact the lower end of the plug and push the plug upward to expose the hole. In order to prevent cow urine from falling directly on the reciprocating control component 218, a cross bar can be connected to the moving end of the reciprocating control component 218 to keep the reciprocating control component 218 away from the bottom of the hole, and the other end of the cross bar can press the plug.

[0124] In some embodiments, the housing 23 can be configured to be split, and can be split into two parts from the position where the pressure sensor 215 is installed, the lower part is the liquid measuring chamber 211, and the upper part is the space for connecting the urine discharge tube 3 and accommodating the weighing box 216. Fig. 9 shown.

[0125] Example 8; Reference Fig. 9 , Fig.10 , further, the urine discharge tube 3 includes a connecting hose 31 and a guiding outer tube 32;

[0126] The connecting hose 31 is connected to the urine collecting cover 1, the guiding outer tube 32 is fixedly connected to the housing 23, and the connecting hose 31 is inserted into the guiding outer tube 32;

[0127] The guide outer tube 32 is tilted, and one end away from the housing 23 is tilted toward the baffle 24;

[0128] One end of the connecting hose 31 close to the housing 23 is fixedly connected with a tension piece 33 , and the tension piece 33 applies a tension force to the connecting hose 31 to move toward one end of the housing 23 .

[0129] Since it takes a long time to monitor and collect the urination of cattle, the activities of cattle cannot be completely restricted for a long time. Therefore, cattle will move in a small range during monitoring and collection. If the urination tube 3 is reserved too short, the cattle's freedom will be restricted when they move. The cattle are also strong, and forced movement can easily cause the urine collection cover 1 and the urination tube 3 to shift in the installation position, or even cause damage. If the installation position is too long, when the cattle move and pull out the urination tube 3 completely, when the cattle move in the opposite direction, there is a certain probability that the urination tube 3 cannot be collected under the slatted plate 5, and is stepped on by the cattle's hoof, causing damage, and a flat pipe section can also be formed so that urine can remain there.

[0130] The connecting hose 31 is arranged in the guide outer tube 32, and the connecting hose 31 is pulled toward the shell 23 by the tension piece 33. When the cow moves toward the distal end, the connecting hose 31 is pulled to overcome the tension of the tension piece 33. At this time, the connecting hose 31 moves with the cow. When the cow returns to a position closer to the guide outer tube 32, the tension piece 33 pulls the redundant connecting hose 31 into the guide outer tube 32 to avoid being stepped on by the cow.

[0131] The guide outer tube 32 provides a guide for the collection of the connecting hose 31, avoiding friction between the connecting hose 31 and the manure-leaking plate 5 when the connecting hose 31 is collected. The guide outer tube 32, which is tilted toward one end of the baffle 24, is installed under the manure-leaking plate 5 and then tilted toward a group of manure-leaking long grooves 51 of the manure-leaking plate 5, so that the connecting hose 31 can pass through the manure-leaking long grooves 51. The connecting hose 31 collected in the guide outer tube 32 also maintains an inclined posture. The connecting hose 31 above the manure-leaking plate 5 is connected to the urine collecting cover 1 fixed to the cow body above, and also maintains an inclined posture, so that the urine discharged when the cow urinates can be completely discharged into the transfer module 2, avoiding the cow urine from remaining in the urine discharge pipe 3.

[0132] The tension member 33 applies tension to the connecting hose 31. Specifically, the tension member 33 can be configured as an elastic rope (such as Fig.10 As shown), a rope with a heavy object hanging below, or an elastic or winding mechanism connected to the other end of the rope, so that the rope can pull the connecting hose 31 downward after being pulled into the guide outer tube 32 along with the connecting hose 31.

[0133] Example 9; Reference Figure 7-Figure 9 , Fig.11 , Fig.12 , further comprising a clamping fixing plate 242, a fixing screw 243 is fixedly connected to the middle of the clamping fixing plate, and a clamping nut 244 is sleeved on the fixing screw 243;

[0134] A fixing hole 241 is provided on the baffle plate 24 at a position away from the housing 23, and a fixing screw 243 can be inserted into the fixing hole 241. A clamping fixing plate 242 and a clamping nut 244 are respectively provided on both sides of the baffle plate 24.

[0135] The width of the clamping plate 242 is smaller than the width of the long manure leakage slot 51 , and the maximum rotation range of the clamping plate 242 along the fixing screw is smaller than the distance from the center of the fixing hole 241 to the side of the shell 23 .

[0136] The cow is in an active state, and the cow body and the transfer module 2 are connected through the urinary tube 3, so when the cow moves, the urinary tube 3 will move together. At this time, the transfer module 2 will also receive a pulling force, which will pull the transfer module 2 to move, causing the position of the transfer module 2 to deflect, which may also affect the monitoring accuracy of the urine volume detection module.

[0137] A clamping space is formed between the clamping fixing plate 242 and the baffle plate 24, and the two sides of the long manure leakage groove 51 on the manure leakage plate 5 are clamped in the clamping space, and the transfer module 2 is fixed to the manure leakage plate 5 to prevent the transfer module 2 from being pulled and deflected.

[0138] The clamping plate 242 is inserted into the fixing hole 241 of the baffle 24 through the fixing screw 243. When the transfer module 2 is placed into the long manure leakage groove 51, the clamping plate 242 is first rotated to the same length direction as the long manure leakage groove 51. After the transfer module 2 is completely placed in the long manure leakage groove 51, the clamping plate 242 is rotated to make the length direction of the clamping plate 242 perpendicular to the length direction of the long manure leakage groove 51, so that the clamping plate 242 and the bottom plate surface of the manure leakage board 5 around the long manure leakage groove 51 overlap. At this time, the clamping nut 244 is rotated to compress the clamping space between the clamping plate 242 and the baffle 24, so that the transfer module 2 and the manure leakage board 5 are completely fixed.

[0139] In some embodiments, an adjusting nut 245 is fixedly disposed at one end of the fixing screw 243 away from the clamping fixing plate 242 , and the angle of the clamping fixing plate 242 can be adjusted by rotating the adjusting nut 245 .

[0140] Example 10; Reference Figure 7-Figure 9 , Fig.11 , Fig.12 , further, a rotation limit block 246 is provided on the clamping and fixing plate 242;

[0141] The rotation limit block 246 is arranged on one side of the clamping and fixing plate 242 where the fixing screw is arranged;

[0142] The rotation limit block 246 is arranged on the circumference of the fixed screw, and has a protrusion 247 on the circumference of the fixed screw that is larger than the width range of the long manure leakage groove 51 on the manure leakage board 5. The protrusion 247 limits the clamping fixed plate 242 from rotating to overlapping with the board surface around the long manure leakage groove 51 and then rotating in the same direction to a position where the overlapping is disengaged.

[0143] When the clamping plate 242 is rotated, when the length direction of the clamping plate 242 is perpendicular to the length direction of the long manure leakage groove 51, the maximum contact area between the clamping plate 242 and the manure leakage board 5 is the optimal clamping angle. However, when the clamping plate 242 is rotated, it is not easy for the staff to see the rotation angle of the clamping plate 242, and there is a problem that after turning around, the clamping plate 242 is parallel to the long manure leakage groove 51 again and the clamping plate 242 is disengaged. When the clamping nut 244 is rotated to clamp the manure leakage board 5, the clamping nut 244 may also drive the clamping plate to move together, causing the setting angle of the clamping plate 242 to be offset.

[0144] In this embodiment, the circumference of the fixing screw is a 360° range centered on the axis of the fixing screw. It is larger than the width of the long manure-leaking groove 51 on the manure-leaking plate 5, that is, the diameter of the circumferential circular range formed by the center line of the bolt is larger than the width of the manure-leaking plate 5. Fig.12 The area outside the double-dashed circle a shown.

[0145] The rotation limit block 246 is used to limit the excessive rotation of the clamping plate 242 when the clamping plate 242 is rotated. Specifically, when the range of the rotation limit block 246 in the circumferential direction of the fixed screw is smaller than the width range of the long manure leakage groove 51, the rotation limit block 246 can rotate freely in the long manure leakage groove 51, and when it is larger than the range of the long manure leakage groove 51, the rotation of the rotation limit block 246 can be blocked by the side wall of the long manure leakage groove 51, so that the rotation of the clamping block and the clamping plate 242 is blocked.

[0146] The angle at which the rotation limit block 246 limits the clamping plate 242 is related to the position of the protruding portion 247 of the rotation limit block 246. The position of the protruding portion 247 outside the width range of the manure leakage slot 51 can be adjusted to adjust its limiting angle. The optimal time is when the length direction of the clamping plate 242 is perpendicular to the length direction of the manure leakage slot 51. At this time, the overlapping range is the largest and the clamping is more stable. Fig.12 The clamping limit plate is rotated in the opposite direction as indicated by the middle arrow, so that the length direction of the clamping fixing plate 242 is parallel to the length direction of the long manure leakage groove 51.

[0147] The setting of the rotation limiter can be as follows Fig.12The wider block shape shown in the figure may also be provided with a protruding portion 247 only outside the width range of the long manure leakage groove 51 in the circumferential direction of the fixed screw, and any shape such as a block, column, plate, etc. that can achieve blocking may be adopted.
