Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of breeding equipment, and in particular to a dung plug inserting and pulling device and a livestock farm sewage discharging machine. BACKGROUND

[0002] In large-scale livestock breeding farms, dung cleaning usually adopts dung scraper (dung scraping plate) to scrape the dung water to the sewage discharge port, and then discharges it through the sewage pipe. In order to prevent harmful gases, liquids or pathogens in the sewage pipe from polluting the environment in the shed through the sewage discharge port, the existing technology generally sets a dung plug as an opening and closing device at the sewage discharge port. The current operation mode of the dung plug mainly has the following defects:

[0003] Manual operation mode: the staff manually pulls up and puts down the dung plug before and after each scraping operation. This mode not only increases labor cost, but also easily leads to personnel fatigue due to frequent operation, and is low in efficiency in the scene of multiple sewage discharge ports in large breeding farms.

DETAILED DESCRIPTION

[0054] In the following, certain example embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not limiting.

[0055] Reference Figures 1-9 Fig. 1 shows a preferred embodiment of the excrement plug plug-in device of the present application, which is used in conjunction with the excrement scraping machine, the excrement scraping machine is provided with a power device and an excrement scraping device 30, the power device is used to drive the excrement scraping device 30 to move horizontally in a straight line, the excrement plug plug-in device comprises:

[0056] The gear 1 is configured to rotate synchronously with the rotary component 10 of the power device, that is, the gear 1 is connected with the rotary component 10, and the gear 1 can rotate with the rotary component 10;

[0057] A rack 2, which can be switched between a first state of engagement with the gear 1 and a second state of disengagement, is provided with a reset control slope 21;

[0058] A first elastic component 3, the two ends of which are respectively hinged to a support base (not shown in the figure) and the rack 2, is used to apply a pre-tightening force to the rack 2 to maintain the first state and ensure reliable engagement of the rack 2 with the gear 1;

[0059] A connecting rod mechanism 4, which is movably arranged on the support base, is hinged to the rack 2 and can move horizontally and linearly with the rack 2;

[0060] A plug-in component 5, which is vertically movable and arranged on the support base, is hinged to the connecting rod mechanism 4 and is used to connect with the manure plug 60, and can move vertically with the connecting rod mechanism 4;

[0061] A reset control component 6, which is arranged on the support base, is slidably matched with the reset control slope 21, and is used to force the rack 2 to switch to the second state when the rack 2 moves backward to a set position, so as to disengage the rack 2 from the gear 1;

[0062] A counterweight component 7, which is connected to the connecting rod mechanism 4, is used to maintain the open state of the manure plug 60 through the balance of the gravitational moment when the plug-in component 5 rises to the open position; and

[0063] A limiting component 8, which is provided on the rack 2, is used to contact the manure scraping device 30 in the forward state to drive the rack 2 to move forward and reset when the rack 2 is in the second state.

[0064] The manure plug insertion and removal device of the present invention, through linkage with the manure scraper and the coordinated cooperation of gear 1, rack 2, connecting rod mechanism 4, insertion and removal component 5, counterweight component 7 and limiting component 8, cleverly utilizes the original power of the manure scraper to achieve fully automatic removal and repositioning of the manure plug 60 without relying on an additional power device, significantly improving equipment utilization and reducing energy consumption costs. Its structural advantages are mainly reflected in the following aspects: First, it adopts a compound motion conversion mechanism of gear 1-rack 2 transmission and linkage mechanism 4, which accurately converts the horizontal movement of the manure scraper into the vertical lifting and lowering movement of the insertion and extraction component 5. The vertical guiding constraint of the support base ensures the straightness of the insertion and extraction trajectory, effectively avoiding action deviation. Second, it integrates the counterweight component 7 into the linkage mechanism 4. During the opening stage of the manure plug 60, the weight of the manure plug 60 is automatically offset by dynamic gravity torque balance. It can stably maintain the opening state without external energy, which greatly improves the reliability of the system. Third, it sets a dual triggering mechanism of reset control inclined surface 21 and limit component 8. When the rack 2 moves backward to the set position, the interaction between the reset control inclined surface 21 and the reset control component 6 forces the gear 1-rack 2 to disengage, realizing motion decoupling. The manure scraper 30 touches the limit component 8 to push the rack 2 backward to complete the reset action of the manure plug 60. The whole process does not require sensor or electronic control intervention. In summary, this manure plug insertion and removal device achieves intelligent state switching and self-locking functions through a purely mechanical structure. While reducing the risk of manual operation, it perfectly matches the working rhythm of the manure scraper and has high engineering practical value.

[0065] Specifically, when the manure plug 60 needs to be removed, the scraping device 30 is driven by the power device to move forward along the manure passage (according to...). Figure 1 As shown in the direction (moving forward, i.e., moving to the left), gear 1 follows the rotating component 10 and rotates counterclockwise. The rotation of gear 1 drives rack 2 to move backward (according to...). Figure 1When the rack 2 moves backward (i.e. moves rightward in the shown direction), the rack 2 moves backward to drive the linkage mechanism 4 to swing clockwise, thereby driving the plug part 5 to rise. Since the plug part 5 is vertically movably arranged on the support base, the plug part 5 is forced to move linearly in the vertical direction, and the plug part 5 rises to drive the fecal plug 60 to rise until the fecal outlet is opened. Meanwhile, during the process of lifting the fecal plug 60, the linkage mechanism 4 swings clockwise, and the counterweight part 7 on the linkage mechanism 4 swings to switch positions to balance the weight of the fecal plug 60 by the gravitational torque, i.e. to balance the weight of the fecal plug 60, so that the counterweight part 7 is sufficient to prevent the fecal plug 60 from falling without other power, until the state is changed by other power. When the rack 2 moves backward to the set position, the reset control slope 21 on the rack 2 contacts the reset control part 6. With the rack 2 continuing to move backward, the reset control slope 21 and the reset control part 6 jointly force the rack 2 to move downward until the rack 2 disengages from the gear 1. At this time, the gear 1 idles and cannot drive the rack 2 to move backward. With the fecal scraping device 30 continuing to move forward, the fecal scraping device 30 contacts the limiting part 8, and the limiting part 8 is driven by the forward pushing force of the fecal scraping device 30 to drive the rack 2 to move forward. The rack 2 drives the linkage mechanism 4 to swing counterclockwise, drives the plug part 5 to descend, and inserts the fecal plug 60 into the fecal outlet until the fecal plug 60 is reset. When the fecal scraping needs to be stopped, the fecal scraping device 30 moves backward to disengage from the limiting part 8, and the rack 2 is reset to engage with the gear 1 under the pre-tightening force of the first elastic part 3. The whole process is coherent and has no power redundancy.

[0066] It should be particularly noted that the support base can be a wall surface or a support frame.

[0067] In an embodiment, the first elastic part 3 can be a spring, an elastic sheet or a bellows.

[0068] In an embodiment, the reset control part 6 is a rotating wheel, i.e. the reset control part 6 is rotatably arranged on the support base to enable the reset control part 6 to rollingly contact the reset control slope 21 to reduce the resistance.

[0069] Of course, in other embodiments, the reset control part 6 can be a bearing, the outer ring of the bearing is rotatable, and the outer ring of the bearing rollingly contacts the reset control slope 21 to also reduce the resistance.

[0070] Referring to Figures 1-4 In an embodiment, the linkage mechanism 4 includes:

[0071] a first linkage 41;

[0072] The second connecting rod 42 is hinged at its first end to the first end of the first connecting rod 41 via a first rotary joint 43, and the first rotary joint 43 is hinged to the rack 2, that is, the first end of the first connecting rod 41, the first end of the second connecting rod 42 and the rack 2 are hinged together via the first rotary joint 43;

[0073] The third connecting rod 44 is hinged at its first end to the second end of the second connecting rod 42 via a second rotary joint 45;

[0074] The lifting swing arm 46 is hinged at its first end to the second end of the first connecting rod 41 via a third rotary joint 47, and the second end of the lifting swing arm 46 is hinged to the second end of the third connecting rod 44 via a fourth rotary joint 48, and the fourth rotary joint 48 is configured on the support base, that is, the fourth rotary joint 48 is fixed on the external support base, and the counterweight component 7 is arranged on the first end of the lifting swing arm 46; and

[0075] The lifting connecting rod 49 is hinged at its first end to the second end of the lifting swing arm 46, and the second end of the lifting connecting rod 49 is hinged to the plug-in component 5. In this way, when the rack 2 moves backward, the first connecting rod 41 and the second connecting rod 42 both swing clockwise around the first rotary joint 43, the third connecting rod 44 swings clockwise around the second rotary joint 45 to drive the lifting swing arm 46 to swing clockwise around the fourth rotary joint, and the lifting connecting rod 49 is lifted upward through the four-bar linkage motion track, so as to smoothly lift the plug-in component 5; the counterweight component 7 swings synchronously with the lifting swing arm 46 to the upper rear of the fourth rotary joint 48, so as to ensure that the counterweight component 7 can balance the weight of the fecal plug 60; when the rack 2 moves forward, the first connecting rod 41 and the second connecting rod 42 both swing counterclockwise around the first rotary joint 43, the third connecting rod 44 swings counterclockwise around the second rotary joint 45 to drive the lifting swing arm 46 to swing counterclockwise around the fourth rotary joint, and the lifting connecting rod 49 is accurately displaced downward through the four-bar linkage motion track, so as to ensure that the plug-in component 5 stably descends; the counterweight component 7 swings synchronously with the lifting swing arm 46 to the upper front of the fourth rotary joint 48. Since the first connecting rod 41 and the second connecting rod 42 move synchronously via the first rotary joint 43, the torque transmission is efficient and stable, and the energy loss in the movement process is reduced; secondly, the four-bar linkage mechanism 4 formed by the first connecting rod 41, the second connecting rod 42, the third connecting rod 44 and the lifting swing arm 46 is kinematically optimized, can accurately control the trajectory of the lifting connecting rod 49, and makes the plug-in component 5 smoothly ascend and descend, avoiding jamming or shaking.

[0076] Referring to Figures 1-4In an embodiment, the first end of the lifting swing arm 46 is provided with a first extension arm 461, the one end of the first extension arm 461 away from the lifting swing arm 46 is connected with the counterweight component 7, and the second end of the lifting swing arm 46 is provided with a second extension arm 462, the one end of the second extension arm 462 away from the lifting swing arm 46 is hinged with the first end of the lifting connecting rod 49. Through the structural design that the first end and the second end of the lifting swing arm 46 are respectively provided with the first extension arm 461 and the second extension arm 462, the counterweight component 7 and the lifting connecting rod 49 are respectively located at the two far ends of the lifting swing arm 46, forming an optimized lever balance system, wherein the first extension arm 461 extends the length of the force arm of the counterweight component 7, significantly improves the counterweight efficiency, and can achieve the same balancing effect with smaller counterweight mass, and at the same time, the second extension arm 462 increases the swing amplitude of the lifting connecting rod 49, ensuring that the plug-in component 5 obtains sufficient lifting stroke.

[0077] In an embodiment, the lifting swing arm 46, the first extension arm 461 and the second extension arm 462 are integrally provided together, that is, the lifting swing arm 46, the first extension arm 461 and the second extension arm 462 are integrally formed, forming an integrated structure, which can not only enhance the overall rigidity, but also avoid the assembly error and loosening risk brought by the additional connecting piece 53.

[0078] Referring to Figures 1-4 In an embodiment, the length extension direction of the first extension arm 461 is parallel to the length extension direction of the lifting swing arm 46, and the length extension direction of the second extension arm 462 is inclined to the length extension direction of the lifting swing arm 46. By setting the first extension arm 461 to extend parallel to the lifting swing arm 46, it is ensured that the counterweight component 7 always moves along the predetermined trajectory to provide stable balancing torque, and at the same time, the second extension arm 462 is inclined to change the force application angle of the lifting connecting rod 49, which not only increases the lifting stroke but also optimizes the force transmission efficiency; in addition, the asymmetric first extension arm 461 and second extension arm 462 structural design through precise calculation of the angle relationship between the two, while ensuring the counterweight balancing effect, significantly improves the action sensitivity of the lifting connecting rod 49, so that the plug-in component 5 can quickly respond to the driving input.

[0079] Referring to Figures 1-3 In an embodiment, the fecal plug plug-in and pull-out device further comprises:

[0080] The guide component 9 is mounted on the support base and has a guide channel (not shown in the figure). The guide channel is vertically oriented and slidably engages with the insertion / removal component 5. Thus, by adding the guide component 9 with the vertical guide channel to the support base and forming a slidable engagement with the insertion / removal component 5, the lifting and lowering trajectory of the insertion / removal component 5 is effectively constrained, ensuring that it always maintains precise vertical linear motion and avoiding swaying or jamming. Secondly, the guide channel ensures smooth movement and reduces unnecessary frictional losses, significantly improving the positioning accuracy and repeatability of the insertion / removal action. Thirdly, the rigid support structure of the guide component 9 shares the lateral load during the insertion / removal process, reducing the stress on the linkage mechanism 4 and extending the service life of key moving parts. Furthermore, the precise engagement between the guide component 9 and the insertion / removal component 5 effectively suppresses vibration and noise during operation, improving the stability and reliability of the plug insertion / removal device.

[0081] See Figures 1-3 In one embodiment, the plug-in / plug-out component 5 includes:

[0082] Lifting shaft 51 is vertically movable and mounted on the support base. The upper end of lifting shaft 51 is hinged to linkage mechanism 4.

[0083] The second elastic member 52, the upper end of which is connected to the lower end of the lifting shaft 51; and

[0084] Connector 53 is located at the lower end of the second elastic member 52 and is used to connect with the plug 60. By designing the insertion / removal component 5 as a combination structure including a lifting shaft 51, a second elastic member 52, and a connector 53, where the lifting shaft 51 is hinged to the linkage mechanism 4 to achieve power input, the second elastic member 52 provides flexible buffering, and the connector 53 achieves a reliable connection with the plug 60, this three-stage structure significantly improves the adaptability and reliability of the plug insertion / removal device while ensuring power transmission efficiency. Specifically, the vertical movement design of the lifting shaft 51 ensures motion accuracy through rigid guidance, and its upper hinge effectively converts the swing of the linkage mechanism 4 into linear motion. The second elastic member 52 compensates for gap changes caused by installation errors and wear of parts, and absorbs impact vibrations during insertion and removal, preventing damage to parts caused by rigid contact. The special design of the connector 53 achieves a reliable connection with the plug 60, ensuring that no accidental loosening occurs during operation.

[0085] Specifically, the connector 53 can be connected to the manure plug 60 by any one or a combination of snap-fit, threaded connection, riveting, etc.

[0086] In one embodiment, the second elastic component 52 may be a spring, an elastic sheet, or a bellows.

[0087] In one embodiment, the limiting component 8 has a socket (not shown in the figure) whose central axis extends along the moving direction of the rack 2, and the socket is used to cooperate with the scraping device 30 to ensure that the limiting component 8 can be reliably connected with the scraping device 30 and improve the reliability of the forward movement of the rack 2.

[0088] Referring to Figures 5-9 , a livestock farm sewage machine according to a preferred embodiment of the present application is shown, which comprises:

[0089] a power device, the power device being provided with a rotating component 10;

[0090] a scraping device 30, the scraping device 30 being connected with the power device, and the scraping device 30 being capable of being driven by the power device to move horizontally and linearly; and

[0091] The above-mentioned fecal plug inserting and pulling device is connected with the rotating component 10 through the gear 1.

[0092] The livestock farm sewage machine of the present application, based on the fecal plug inserting and pulling device and the cooperation of the gear 1, the rack 2, the connecting rod mechanism 4, the inserting and pulling component 5, the counterweight component 7 and the limiting component 8, can automatically pull up and reset the fecal plug 60 without relying on additional power devices, and can significantly improve the utilization rate of the equipment and reduce the energy consumption cost. The structural advantages mainly include the following aspects: first, the gear 1-rack 2 transmission and the composite motion conversion mechanism of the connecting rod mechanism 4 can accurately convert the horizontal movement of the scraping machine into the vertical lifting movement of the inserting and pulling component 5, and the vertical guidance constraint of the supporting base can ensure the linearity of the insertion and pulling track and effectively avoid the action deviation; second, the counterweight component 7 is integrated into the connecting rod mechanism 4, and the dynamic gravity moment balance can automatically offset the weight of the fecal plug 60 during the opening stage of the fecal plug 60, so that the opening state can be stably maintained without external energy, and the system reliability is greatly improved; third, the double triggering mechanism of the reset control slope 21 and the limiting component 8 is set, when the rack 2 moves backward to a set position, the interaction between the reset control slope 21 and the reset control component 6 forces the gear 1-rack 2 to disengage, realizing the motion decoupling, and the scraping device 30 pushes the limiting component 8 to move the rack 2 backward to complete the resetting action of the fecal plug 60, and the whole process does not need sensor or electric control intervention.

[0093] Referring to Figures 5-7 In one embodiment, the livestock farm sewage machine further comprises:

[0094] a third elastic component 40, a first end of the third elastic component 40 being connected with the scraping device 30; and

[0095] The front pushing component 50 is arranged on the second end of the third elastic component 40, and is used to contact the limiting component 8 when the rack 2 is in the second state. By integrating the third elastic component 40 on the scraper device 30 and arranging the front pushing component 50, the front pushing component 50 forms controllable contact with the limiting component 8 when the rack 2 is switched to the second working state. This design ensures that the scraper device 30 generates a continuous and stable forward driving force on the rack 2 through elastic support, and effectively absorbs dynamic impact during the movement of the mechanism by the buffering characteristics of the third elastic component 40. The double-acting mechanism not only ensures the reliability of the forward movement of the rack 2, but also greatly reduces the wear of components caused by rigid collision by absorbing kinetic energy through elastic deformation. In an embodiment, the third elastic component 40 can be a spring, an elastic sheet or a bellows.

[0096] Referring to Figures 5-7 In an embodiment, the front pushing component 50 is provided with a front pushing inclined surface 501 and a front pushing limiting surface 502. The front pushing inclined surface 501 is used to guide the insertion of the front pushing component 50 into the insertion hole of the limiting component 8 to realize insertion guidance. The front pushing limiting surface 502 is located behind the front pushing inclined surface 501 and abuts against the limiting component 8 to realize self-locking to ensure that the front pushing component 50 and the limiting component 8 are reliably connected together. In this way, through the synergistic effect of inclined surface guidance and flat surface limiting, both rapid alignment and installation and anti-displacement stability in the working state are realized. The inclination of the front pushing inclined surface 501 makes the insertion process smooth and smooth without the need for additional force, and the front pushing limiting surface 502 ensures that the contact area is maximized to disperse the load. In particular, this dual-function surface structure can simultaneously complete the two processes of guided insertion and rigid locking through one action, greatly simplifying the operation process, and the self-locking feature can effectively resist loosening caused by vibration.

[0097] Referring to Figures 8-9 It should be particularly noted that the rotating component 10 is specifically a winding wheel of a power device. The power device further includes a traction rope 20. One end of the traction rope 20 is connected to the winding wheel, and the other end of the traction rope 20 is connected to the scraper device 30. The traction rope 20 is movably wound on the rotating component 10. The traction rope 20 is controlled to be retracted or extended by the forward and reverse rotation of the rotating component 10, so as to accurately drive the horizontal reciprocating movement of the scraper device 30.
