Description

Technical Field

[0001] This invention belongs to the field of livestock machinery technology, and specifically relates to a manure cleaning vehicle in which the transmission components are isolated from the manure scraping area. Background Technology

[0002] With the development of livestock farming, especially cattle and sheep farming, large-scale farming has become a trend. While this brings benefits to farmers, it also brings many problems, such as the disposal of large amounts of livestock manure. It is well known that if large amounts of manure are not disposed of promptly and effectively, they not only occupy feeding space, but the putrid smell and damp environment can also cause livestock to contract and spread diseases such as cholera and stomatitis. Therefore, manure removal trucks are being used by an increasing number of farmers.

[0003] Most existing manure cleaning trucks use lifting chains and lifting sprockets to drive the scraper blades to rotate, lifting the manure and transporting it to the truck's storage bin. The lifting chain connected to the scraper blades is in direct contact with the manure, which causes it to be corroded by the manure, affecting its service life and requiring frequent replacement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, a manure cleaning vehicle with transmission components isolated from the manure scraping area is proposed. This solves the technical problem in existing technologies where the chain and sprocket are in direct contact with manure and are subject to corrosion, thus affecting their service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

One end of the support frame is fixed to the inner wall of the isolation chamber, and the other end passes through the opening and connects to the external support component. The transmission component is located inside the isolation chamber to isolate it from the manure-scraping area. The connecting crank arm is offset relative to the support frame. One end of the connecting crank arm is connected to the transmission component, and the other end passes through the opening and connects to the manure-scraping scraper.

[0018] The technical solution is further configured such that the scraper base plate is connected to the support frame by an adjustable structure to eliminate the gap between the scraper blade and the scraper base plate caused by overall wear.

[0019] Preferably, the adjustable structure consists of multiple sets of connecting screws distributed on the left and right sides.

[0020] The technical solution is further configured such that the isolation chambers are arranged symmetrically on the left and right, and the drive unit of the transmission component is located between the two isolation chambers and is connected to the transmission component in a transmission connection.

[0021] The technical solution is further configured such that the front end of the box body and the rear end of the cab both have inclined surfaces, the slope of the inclined surfaces is consistent with the scraping and lifting angle of the scraping and lifting mechanism, and the inclined surfaces have grooves that match the width of the scraping and lifting mechanism. The bottom surface of the grooves is parallel to the inclined surfaces, and the two grooves completely cover the scraping and lifting mechanism. The cab is fixed on the inclined surfaces of the box body.

[0022] The technical solution is further configured such that the front end of the box has a first inclined surface, the slope of the first inclined surface is consistent with the scraping and lifting angle of the scraping and lifting mechanism, and the first inclined surface has a groove that matches the width of the scraping and lifting mechanism. The bottom surface of the groove is parallel to the first inclined surface, and the scraping and lifting mechanism is completely embedded in the groove. The rear end of the cab is configured as a second inclined surface that is parallel to the first inclined surface, and the cab is fixed on the first inclined surface.

[0028] The technical solution is further configured such that heating coils are attached to the outer walls on both sides of the lower half of the housing, the heating coils are controllably connected to the cooling unit of the engine assembly, and the heating coils are covered with an insulation layer.

[0029] The technical solution is further configured such that the tank is equipped with a liquid level indicator component, which includes a float, a connecting rod, and an indicator.

The middle part of the indicator is connected to the top of the connecting rod via a connecting arm, and the bottom of the connecting rod is connected to the float located inside the tank. When the fecal liquid level inside the tank reaches a set value, the other end of the indicator extends beyond the width of the tank, making it easy for the driver to identify from the rearview mirror of the septic tank truck.

[0030] The technical solution is further configured such that a float overflow hole is provided on the box body, and a float overflow cavity is provided on the outside of the box body corresponding to the float overflow hole. The connecting rod passes through the float overflow cavity, and a rubber pad with several radial slits is provided at the bottom of the float overflow cavity. The float can be opened and partially pass through the rubber pad to enter and exit the float overflow cavity.

[0031] The technical solution is further configured such that the box body is provided with a float guide frame connected to the float overflow cavity, and the float floats up and down inside the float guide frame.

[0034] By setting up an isolation chamber, the transmission components are placed inside the isolation chamber, thus isolating the transmission components from the manure scraping area. This prevents the chain and sprocket from directly contacting the manure and being corroded by it, extending their service life. At the same time, the transmission components are located in a relatively enclosed isolation chamber, which allows for effective lubrication, thereby greatly extending the service life of the transmission components.

[0052] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0053] According to an embodiment of the present invention, a manure cleaning vehicle is provided in which the transmission components are isolated from the manure scraping area. Please refer to [link to relevant documentation]. Figure 1 The vehicle includes a housing 100, a manure scraping and lifting mechanism 200, a V-shaped collection end 300, a cab 400, and front and rear axles. The front and rear axles are mounted on the housing 100. The V-shaped collection end 300 is connected to the manure scraping and lifting mechanism 200, which is inclined to form a certain manure scraping and lifting angle. The manure scraping and lifting mechanism 200 is driven by an actuator mounted on the housing 100, moving up and down along the manure scraping and lifting angle, allowing the vehicle to switch between manure scraping and on-site transportation modes. In use, the manure truck, with its transmission components isolated from the manure scraping area, moves slowly forward. During this process, the V-shaped collection end 300 collects the manure, and the manure scraping and lifting mechanism 200 lifts the collected manure into the housing 100 for temporary storage.

[0054] Please see Figure 1 and Figure 9The manure scraping and lifting mechanism 200 includes an isolation chamber 201, a support frame 202, a transmission component 203, a connecting crank arm 204, and a manure scraper 205. The isolation chamber 201 is a closed structure with an opening on the outside, which is the side of the isolation chamber 201 away from the manure scraping area. One end of the support frame 202 is fixed to the inner wall of the isolation chamber 201, and the other end passes through the opening and is connected to the external support component. The transmission component 203 is disposed inside the isolation chamber 201 to isolate the transmission component 203 from the manure scraping area. The connecting crank arm 204 is offset relative to the support frame 202. One end of the connecting crank arm 204 is connected to the transmission component, and the other end passes through the opening and is connected to the manure scraper 205.

[0055] It should be noted that by setting up an isolation chamber 201, the transmission component 203 is located inside the isolation chamber 201, thus isolating the transmission component 203 from the manure scraping area. This prevents the chain 213 and sprocket 211 from directly contacting the manure and being corroded by it, thereby extending their service life. The transmission component 203 drives the manure scraper 205 to operate. During this process, the manure scraper 205 carries and lifts the manure to form the manure scraping area. The transmission component 203 drives several manure scraper 205 to reciprocate, achieving continuous manure scraping.

[0056] In addition, the manure scraping and lifting mechanism 200 also includes a lubrication assembly (not shown in the figure) for automatic lubrication of the transmission components. In this embodiment, the lubrication assembly uses a plunger pump to deliver lubricating oil from the oil tank to the transmission components through a metering injector, distributor, and delivery oil pipe. The vehicle control system accumulates the manure scraping operation time, and when a set threshold is reached, it starts the plunger pump to achieve automatic lubrication. By setting the lubrication assembly, the transmission components can be made maintenance-free, thereby greatly extending the service life of the manure cleaning truck.

[0057] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figures 4 to 6 , Figure 9 and Figure 10 Along a straight running direction perpendicular to the transmission component, the connecting crank arm 204 is connected to the transmission component via a connector, on which a shock-absorbing roller 207 is provided. Simultaneously, a scraper posture-maintaining roller 208, offset relative to the shock-absorbing roller 207, is also provided on the connector. Furthermore, along the straight running direction of the transmission component, the inner wall of the isolation cavity 201 is provided with a straight groove 212, which restricts the shock-absorbing roller 207 and the scraper posture-maintaining roller 208 to roll within the straight groove 212.

[0058] It should be noted that the linear travel of the transmission components is relatively long, especially the polygonal effect of chain drives, which is prone to vibration during operation. By setting several shock-absorbing rollers 207, and by setting straight grooves 212 to limit the shock-absorbing rollers 207, vibration reduction and shock absorption are achieved. Preferably, the transmission components are chain drives, belt drives, etc.

[0059] Specifically, when the transmission component adopts chain drive, the connecting crank arm 204 is connected to the chain 213 of the chain drive through a fixed link 214. The fixed link 214 is connected to the chain link through a pin. The fixed link 214, as part of the chain 213, is driven by the sprocket 211 of the chain drive. A shock-absorbing roller 207 is provided between the two pins of the fixed link 214. Along the straight running direction of the chain 213, the inner wall of the isolation cavity 201 is provided with a straight groove 212, so that the shock-absorbing roller 207 is restricted to rolling within the straight groove 212. This can effectively reduce the vibration of the chain 213 during the manure scraping process. Sometimes the vibration causes resonance with a large amplitude, resulting in a large gap between the manure scraper 205 and the manure scraper base plate 206, causing manure leakage, affecting the manure scraping effect, and generating noise. This structure not only solves the problem but also increases the life of the chain 213.

[0060] Please see Figure 1 , Figures 4 to 6 , Figures 9 to 11 One end of the fixed link 214 is provided with a scraper attitude holding roller 208 offset relative to the shock-absorbing roller 207. Similarly, the scraper attitude holding roller 208 is restricted to rolling within the straight groove. During the manure scraping and lifting process, the scraper attitude holding roller 208 is restricted within the straight groove, which also reinforces the manure scraper 205 to maintain a fixed angle, ensuring stable contact between the manure scraper 205 and the manure scraper base plate 206 and preventing manure leakage.

[0061] It should be noted that the shock-absorbing roller 207 and the scraper attitude-maintaining roller 208 can roll in the same straight groove or in different straight grooves. Furthermore, the pitch of the scraper attitude-maintaining roller 208 relative to the shock-absorbing roller 207 is adjustable. That is, the fixed link 214 itself is connected to the chain link via a pin. As part of the chain 213, one end of the fixed link 214 is connected to the connecting crank arm 204, and the other end of the fixed link 214 is equipped with both the shock-absorbing roller 207 and the scraper attitude-maintaining roller 208.

[0062] Furthermore, the rotating part of the transmission component includes a high point and a low point. At the high point, the scraper blade 205 changes from a fully loaded state to an unloaded state; at the low point, it changes from an unloaded state to a fully loaded state. When the unloaded scraper blade 205 enters the fecal liquid surface, it experiences significant fecal resistance. Scrapers with traditional structures are prone to springback deformation, as seen in CN202121192007.X. Therefore, a steering cam 209 is provided inside the isolation chamber 201, located at the rotating part of the transmission component.

[0063] Specifically, a steering cam 209 is provided inside the isolation chamber 201 and at the rotating part of the chain 213. During the rotation of the scraper blade 205, the scraper posture maintaining roller 208 is always in tangential contact with the steering cam 209, so that the scraper blade 205 can maintain rigidity when encountering fecal resistance, and prevent the scraper blade 205 from rebounding and deforming.

[0064] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figure 8 and Figure 9 The scraper blade 205 contacts the scraper base plate 206, which is arranged along a straight running direction parallel to the transmission component, and an acute angle is formed between the scraper blade 205 and the scraper base plate 206.

[0065] It should be noted that the scraper blade 205 is inclined towards the manure inlet end of the scraper lifting mechanism 200, causing the scraper blade 205 to form an acute angle with the scraper base plate 206, preventing some manure from remaining in the scraper blade 205 when it turns. Preferably, the scraper lifting mechanism 200 can be arranged along the inclined direction or along the vertical direction.

[0066] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figure 6 , Figure 7 and Figure 10 The scraper blade 205 has wing plates 215 perpendicular to it at both ends. The wing plates 215, the scraper blade 205 and the scraper base plate 206 form a chamber with an upper opening to accommodate feces, preventing feces leakage.

[0067] Preferably, the wing plate 215 is a triangular wing plate. The first side of the triangular wing plate is disposed on the scraper plate 205, the second side of the triangular wing plate contacts the scraper base plate 206, and the third side of the triangular wing plate forms an acute angle with the scraper base plate 206. A triangular chamber with an upper opening is formed between the triangular wing plate, the scraper plate 205, and the scraper base plate 206. The acute angle formed by the triangular wing plate and the scraper base plate 206 is equal to the scraping lifting angle of the scraper lifting mechanism 200, thereby maximizing the volume of the triangular chamber. Preferably, the scraping lifting angle is 60°.

[0068] For preferred options, please refer to [link / reference]. Figure 11 The wing plate 215 is a trapezoidal wing plate, and the top of the scraper plate 205 is bent to form a flange to increase strength. The first waist of the trapezoidal wing plate is located on the scraper plate 205, and the lower bottom edge of the trapezoidal wing plate contacts the scraper base plate 206. The second waist of the trapezoidal wing plate forms an acute angle with the scraper base plate 206. A trapezoidal chamber with an upper opening is formed between the trapezoidal wing plate, the scraper plate 205, and the scraper base plate 206. The acute angle formed by the trapezoidal wing plate and the scraper base plate 206 is equal to the scraping lifting angle of the scraper lifting mechanism 200, thus maximizing the volume of the trapezoidal chamber. Preferably, the scraping lifting angle is 60°.

[0069] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 10 and Figure 11 The scraper blade 205 has a notch at the edge where it contacts the scraper base plate 206. A rubber scraper blade 217 is provided on the scraper blade 205 to cover the notch. The relative position of the rubber scraper blade 217 and the scraper blade 205 is adjustable to compensate for the notch after the rubber scraper blade 217 wears.

[0070] It should be noted that the notch, combined with the rubber scraper 217, allows small gravel and larger sand particles to pass through, reducing the impact noise and damage caused by sand and small stones getting stuck between the scraper 205 and the scraper base plate 206, and increasing fault tolerance. At the same time, the relative position of the rubber scraper 217 and the scraper 205 is adjustable, used to compensate for wear on the rubber scraper 217 and cover the notch. Wear on the rubber scraper 217 can be adjusted for compensation, or even replaced.

[0071] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figure 9 , Figure 12 and Figure 13The upper and lower ends of the isolation cavity 201 are provided with multi-turn U-shaped isolation wing plates 216 coaxial with the transmission shaft of the transmission component. The U-shaped isolation wing plates 216 are perpendicular to the opening end face of the isolation cavity, and the height of the U-shaped isolation wing plates 216 does not interfere with the operation of the connecting crank arm 204.

[0072] It should be noted that the U-shaped isolation wing 216 helps to isolate feces, preventing them from entering the isolation chamber 201 through the opening and corroding the transmission components. Simultaneously, the multiple coaxial turns of the U-shaped isolation wing 216 make it difficult for feces to enter the isolation chamber 201, ensuring that the transmission components within the isolation chamber 201, such as the chain 213 and sprocket 211, are not corroded, greatly increasing the lifespan of the transmission components. Especially at the lower end of the isolation chamber, where there is an abnormal increase in fecal fluid and feces repeatedly come into contact with the lower end, the multiple turns of the U-shaped isolation wing 216 form a kind of partition, increasing the distance the feces travel and reducing the probability of feces entering the isolation chamber 201.

[0073] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 and Figure 9 The scraper base plate 206 is connected to the support frame 202 by an adjustable structure to eliminate the gap between the scraper blade 205 and the scraper base plate 206 caused by overall wear.

[0074] Preferably, the adjustable structure consists of multiple sets of connecting screws distributed on the left and right sides. When the scraper base plate 206 wears during use, the distance between the scraper scraper 205 and the scraper base plate 206 can be adjusted by turning the connecting screws to compensate for the wear gap.

[0075] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figure 6 and Figure 9 The isolation chambers 201 are symmetrically arranged on the left and right sides, and the drive unit of the transmission component is located between the two isolation chambers 201, improving the integration and aesthetics of the manure scraping and lifting mechanism 200. Simultaneously, the drive unit of the transmission component is connected to the transmission component via a transmission link. Specifically, the drive unit of the transmission component is connected to the sprocket shaft 210 of the chain drive. The drive unit of the vehicle-mounted transmission component is mostly a hydraulic motor. Hydraulic motors themselves do not require heat dissipation and can be placed in a closed space. Therefore, the drive unit can be located in the middle area of ​​the two isolation chambers, connected to the transmission shaft of the transmission component via a drive sprocket. The drive unit and drive sprocket are enclosed inside a sealed housing, making the drive unit invisible from the outside of the manure scraping and lifting mechanism 200, saving space and resulting in a simple overall design.

[0076] It should be noted that the scraper base plate 206 is mounted on the base plate frame, and the base plate frame is provided with a cover plate. The base plate frame and the cover plate form a cavity to accommodate the scraper lifting mechanism 200.

[0077] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figures 1 to 3 The front end of the box body and the rear end of the cab both have inclined surfaces. The angle between the inclined surfaces and the horizontal plane is 0°-90°. The slope of the inclined surfaces is consistent with the scraping and lifting angle of the scraping and lifting mechanism 200. The inclined surfaces have grooves that match the width of the scraping and lifting mechanism. The bottom surface of the grooves is parallel to the inclined surfaces. The two grooves completely cover the scraping and lifting mechanism 200. The cab 400 is fixed on the inclined surface of the box body 100.

[0078] It should be noted that by setting slopes and grooves at both the front end of the box and the rear end of the cab, the manure scraping and lifting mechanism 200 is completely accommodated in the two grooves, which can effectively utilize space and achieve a shorter overall length for the same box volume, thereby improving driving flexibility.

[0079] In some other embodiments, the front end of the housing has a first inclined surface, the slope of which is consistent with the scraping and lifting angle of the scraping and lifting mechanism 200, and the first inclined surface has a groove that matches the width of the scraping and lifting mechanism, the bottom surface of which is parallel to the first inclined surface, the scraping and lifting mechanism 200 is completely embedded in the groove, the rear end of the cab is set as a second inclined surface parallel to the first inclined surface, and the cab 400 is fixed on the first inclined surface.

[0080] It should be noted that by opening the groove only on the first inclined surface, the manure scraping and lifting mechanism 200 can be completely accommodated in the groove, which can also achieve a shorter overall length, improve driving flexibility, and simplify the structure of the cab 400.

[0081] In other words, the manure scraping and lifting mechanism 200 can be fully embedded in the box 100, or embedded in the area between the cab 400 and the box 100, so that the space on both sides of the manure scraping and lifting mechanism 200 can be used as the storage capacity of the box 100. It also makes it easier to center the V-shaped collection end 300 and collect manure. The cab 400 covers the manure scraping and lifting mechanism 200 and is centered, making the vehicle more aesthetically pleasing and simple.

[0082] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figures 1 to 3The lower half of the box has an elliptical longitudinal section, making full use of the space between the front and rear wheels of the vehicle. The upper half of the box has a rectangular longitudinal section, effectively increasing the load capacity of the vehicle while shortening its length. The bottom of the lower half of the box has a circular downward protrusion 101, providing an effective corner for the installation of the discharge and mixing auger 102. The discharge and mixing auger 102 is located inside the box and at the center line of the circular downward protrusion 101. A discharge door 103 for discharging feces from the box is located at the rear of the box and corresponding to the discharge and mixing auger 102.

[0083] It should be noted that when the discharge and stirring auger 102 rotates in the forward direction, it discharges the feces from the box. When the discharge and stirring auger 102 rotates in the reverse direction, it agitates the feces in the box 100 to prevent sedimentation.

[0084] Furthermore, the contact surface between the discharge gate 103 and the discharge gate frame is covered with a sealing rubber layer. The discharge gate 103 can be vertically raised and lowered under the drive of the actuator. The discharge gate frame is fixed to the outlet of the discharge and stirring auger 102. The central hole on the discharge gate frame is consistent with the inner diameter of the circular downward protrusion 101. Guide grooves are provided on both sides of the discharge gate frame. A wedge-shaped inclined block 104 with a narrow top and a wide bottom is provided on the inner wall of the outer side of the guide groove, so that the discharge gate 103 in the process of descending presses against the inner wall of the guide groove.

[0085] It should be noted that by setting the wedge-shaped inclined block 104, the distance between the discharge gate 103 and the central hole on the discharge gate frame gradually decreases during the descent of the discharge gate 103, which squeezes the feces and prevents leakage.

[0086] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figures 1 to 3 It also includes an engine assembly 500, which is located at the rear end of the housing and above the portion of the discharge and mixing auger 102 that extends out of the housing. That is, the length of the discharge and mixing auger 102 is greater than the length of the housing 100, reserving installation space for the engine assembly 500.

[0087] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figures 1 to 3 Heating coils are attached to the outer walls on both sides of the lower half of the housing. The heating coils are controllably connected to the cooling unit of the engine assembly 500. The heating coils are covered with an insulation layer.

[0088] It should be noted that the waste heat from the cooling unit of the engine assembly 500 is used to heat the lower half of the box body. At the same time, an insulation layer is used to keep it warm and prevent the feces inside the box body 100 from freezing in extremely cold weather in the north.

[0089] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figures 14 to 16 The tank is equipped with a liquid level indicator assembly 600, which includes a float 601, a connecting rod 602, and an indicator 603. The indicator 603 is located outside the rear end of the tank, one end of the indicator 603 is hinged to the tank 100, the middle part of the indicator 603 is connected to the top of the connecting rod 602 through a connecting arm 604, and the bottom of the connecting rod 602 is connected to the float 601 located inside the tank 100.

[0090] It should be noted that as the sewage level inside the container 100 rises and falls, the float 601 and connecting rod 602 rise and fall synchronously, which in turn pulls the indicator 603 to rotate via the connecting arm 604. When the sewage level inside the container 100 reaches the set value (maximum value), the indicator 603 is in a horizontal state. At this time, the other end of the indicator 603 extends beyond the width of the container 100, making it easy for the driver to identify from the rearview mirror of the sewage truck.

[0091] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figures 14 to 16 The housing 100 has a float overflow hole, and the housing 100 has a float overflow cavity 605 on the outside corresponding to the float overflow hole. The connecting rod 602 passes through the float overflow cavity 605. The bottom of the float overflow cavity 605 is provided with a rubber pad 606 having a plurality of radial slits. The float 601 can be opened and partially pass through the rubber pad 606 to enter and exit the float overflow cavity 605.

[0092] It should be noted that by setting a rubber pad 606 with several radial slits, splashed fecal liquid can be prevented from entering the float overflow cavity 605 to the greatest extent. At the same time, the float 601 can be opened and partially pass through the rubber pad 606 to enter and exit the float overflow cavity 605.

[0093] For the manure removal vehicle in this embodiment where the transmission components are isolated from the manure scraping area, please refer to [link / reference needed]. Figure 1 , Figures 14 to 16 The housing 100 is provided with a float guide frame 607 connected to the float overflow cavity 605, and the float 601 floats up and down inside the float guide frame 607.

[0094] It should be noted that by setting the float guide frame 607, the disturbance effect of the surging of the fecal liquid surface on the connecting rod 602 is prevented, thus preventing the connecting rod 602 from breaking.

[0095] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
