Description

Technical Field

[0001] The utility model relates to the technical field of feed distribution, in particular to a precision metering feed distribution trolley. Background Art

[0002] In the field of animal husbandry, large-scale farms increasingly require accurate feed metering. To this end, existing farms usually use feeding vehicles equipped with electromagnetic metering valves for accurate feed feeding.

[0003] For example, patent publication number CN208228058U discloses a stepper motor-based precision feeding device for poultry farming. The device comprises a self-propelled carriage mounted on a poultry pen, with at least one hopper on either side for feeding feed into the poultry trough. The carriage is driven by a first stepper motor mounted on the carriage, and each hopper outlet is equipped with a feed metering and output mechanism controlled by a second stepper motor. The purpose of this utility model is to provide a stepper motor-based precision feeding device for poultry farming that accurately feeds poultry, enabling targeted, precise feeding of poultry within a pen.

[0004] Combined with the existing technology, it is found that most of the existing feed delivery carts for precise metering feeding need to be equipped with multiple sensors, which are used to match and locate the feed trough and the feeder itself, and require corresponding control equipment and control systems to be used in conjunction. This undoubtedly increases the equipment cost for precise metering feeding. At the same time, although the sensors are easy to use, they are prone to generate erroneous detection signals when strong magnetic interference, current interference or other interference phenomena occur, resulting in errors or difficulties in feeding operations. Therefore, their reliability needs to be improved. Utility Model Content

[0047] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] The utility model provides a precise metering feed distribution trolley through improvement. The technical solution of the utility model is:

[0049] like Figure 1-Figure 5 As shown, a precision metering feed distribution trolley includes:

[0050] A track-carrying vehicle 1 that moves along the feeding track of the farm;

[0051] Feed storage bin 2 is fixed on the rail vehicle 1 and passes through the middle of the rail vehicle 1. A feeding hopper and a discharge port are provided at the upper and lower ends of the feed storage bin 2 respectively. The discharge port of the feed storage bin 2 is located at the lower end of the rail vehicle 1. When the rail vehicle 1 moves to coincide with the position of the feed trough of the farm, the discharge port of the feed storage bin 2 is located directly above the feed trough of the farm;

[0052] Among them, a mounting block 201 is fixed on one side of the feed storage bin 2 close to the livestock and poultry breeding cages in the farm;

[0053] The transmission rod 6, the lower end of the transmission rod 6 rotates through the mounting block 201 and the carrier plate of the rail vehicle 1 and extends to the lower end of the carrier plate of the rail vehicle 1;

[0054] A trigger rod 7, one end of which is fixed to the middle of the transmission rod 6;

[0055] The blanking baffle 9 has one end fixed to the lower end of the transmission rod 6 through a connecting column.

[0056] From the above connection relationship, it can be seen that Figure 1 and attached Figure 2 Under normal conditions (i.e., when the rail vehicle 1 is moving, the trigger rod 7 does not coincide with the position of the vertical rod above the feed trough of the farm, and the transmission rod 6 does not rotate), the unloading baffle 9 closes the discharge port at the lower end of the feed storage bin 2. When the other end of the trigger rod 7 coincides with the position of the vertical rod above the feed trough of the farm during movement, the trigger rod 7 deflects and drives the transmission rod 6 to rotate. When the transmission rod 6 rotates, the unloading baffle 9 rotates with the transmission rod 6 and opens the discharge port at the lower end of the feed storage bin 2, thereby feeding the feed into the feed trough. As the rail vehicle 1 moves forward, the discharge port at the lower end of the feed storage bin 2 does not leave the area of the feed trough of the farm. When the feed is fed into the feed trough, the other end of the trigger rod 7 is separated from the vertical rod above the feed trough of the farm. At this time, the trigger rod 7 is reset under the action of the reset member and the transmission rod 6 is reset at the same time, so that the unloading baffle 9 is reset again to close the discharge port at the lower end of the feed storage bin 2, and the feed feeding operation is completed. Since the discharge speed of the discharge port of the feed storage bin 2 is constant, the opening time of the discharge port of the feed storage bin 2 can be adjusted by adjusting the travel speed of the rail vehicle 1, so as to achieve the purpose of quantitative feed feeding, the measurement is more accurate, and the mechanical triggering method is not affected by the external magnetic field, current and voltage, and is more stable and reliable during the working process;

[0057] At the same time, it eliminates the need for a variety of sensors, control devices, and control systems, thereby reducing equipment costs and making it more suitable for the comprehensive promotion of the precise metering feed distribution vehicle.

[0058] Furthermore, it also includes:

[0059] The servo motor 3 is fixed to the upper end of the feed storage bin 2 through a fixing frame, and the output shaft of the servo motor 3 extends downward;

[0060] The shaft sleeve 4 is fixed to the lower end of the output shaft of the servo motor 3;

[0061] The transmission shaft 5, the lower end of which is movable and passes through the inner wall of the feed storage bin 2 and extends to the lower part of the feed storage bin 2, is fixed with a number of homogenizing rods 501 in the middle of the transmission shaft 5 for disturbing the feed to make it homogenous, and the lower end of the transmission shaft 5 is fixed with a conical screw dragon 502 for assisting in discharging, and the conical screw dragon 502 is adapted to the discharge port of the feed storage bin 2. As can be seen from the above connection relationship, combined with the attached Figure 1 and attached Figure 4When the rail vehicle 1 moves forward, the servo motor 3 is started, which can drive the transmission shaft 5 to rotate through the shaft sleeve 4, and then drive the homogenizing rod 501 and the conical auger 502 to rotate synchronously. The homogenizing rod 501 can disturb and homogenize the feed in the feed storage bin 2, which is conducive to uniform feeding of mixed feed of the same quality. When the conical auger 502 is located inside the discharge port at the lower end of the feed storage bin 2, it can assist in feeding, making the feed flow at the discharge port more stable, which is conducive to accurate metering and feeding.

[0062] The upper end of the transmission shaft 5 is integrally formed with a square shaft 503, and the upper end of the square shaft 503 is slidably inserted into the square groove at the lower end of the sleeve 4;

[0063] Transmission structure, the transmission structure is installed between the transmission shaft 5 and the transmission rod 6. From the above connection relationship, it can be seen that the transmission structure is installed between the transmission shaft 5 and the transmission rod 6. Figure 1 , Attachment Figure 4 And attached Figure 5 When the transmission rod 6 rotates, the transmission shaft 5 is driven down through the transmission structure and the conical auger 502 is located inside the discharge port of the feed storage bin 2, thereby better cooperating with the discharge baffle 9 to assist in the discharge of the feed;

[0064] When the transmission rod 6 is reset, the transmission shaft 5 is driven upward by the transmission structure to make the conical auger 502 leave the discharge port of the feed storage bin 2, so that the conical auger 502 loses its auxiliary feeding function when the feed is not discharged, thereby preventing the conical auger 502 from remaining in the discharge port of the feed storage bin 2 and obstructing the operation of the transmission shaft 5. At the same time, it prevents the feed from being driven by the conical auger 502 to squeeze out of the discharge port of the feed storage bin 2 and press the discharge baffle 9, thereby damaging it.

[0065] The arrangement of the square shaft 503 and the shaft sleeve 4 can ensure that the transmission shaft 5 is always driven by the output shaft of the servo motor 3 to rotate while meeting the lifting and lowering requirements of the transmission shaft 5 .

[0066] Furthermore, the transmission structure includes:

[0067] A lifting plate 14, one end of the lifting plate 14 is fixed to the upper end of the transmission shaft 5, and the other end of the lifting plate 14 extends toward the side close to the transmission rod 6;

[0068] The guide rod 15 is fixed to the upper end of the feed storage bin 2, and the upper end of the guide rod 15 slides through the middle of the lifting plate 14;

[0069] A swing rod 12, one end of which is fixed to the upper end of the transmission rod 6;

[0070] Lift the wedge 13, and fix one side of the lifting wedge 13 to the end of the rocker arm 12 away from the transmission rod 6;

[0071] Among them, the upper end of the lifting wedge block 13 and the side wall of the lifting wedge block 13 facing the lifting plate 14 are formed with an arc-shaped guide surface 1301. Figure 1 and attached Figure 5 When the transmission rod 6 is not rotated, the lifting wedge 13 is in the initial position. At this time, the lifting wedge 13 pushes up the lifting plate 14, thereby lifting the transmission shaft 5 to a certain height and causing the conical auger 502 at the lower end of the transmission shaft 5 to leave the discharge port of the feed storage bin 2, so that the conical auger 502 loses its function of assisting in unloading. When the transmission rod 6 rotates, the transmission rod 6 drives the lifting wedge 13 to rotate a certain angle through the rocker arm 12, so that the lifting wedge 13 loses its lifting effect on the lifting plate 14. At this time, the transmission shaft 5, the homogenizing rod 501 and the conical auger 502 descend under the action of their own gravity, and the conical auger 502 enters the discharge port at the lower end of the feed storage bin 2, playing a role in assisting in unloading.

[0072] During the resetting process of the lifting wedge 13 , that is, when the transmission rod 6 is reset, the lifting wedge 13 contacts the lower end of the lifting plate 14 again through the arc-shaped guide surface 1301 and drives the lifting plate 14 to rise, thereby achieving the purpose of lifting the conical auger 502 .

[0073] Furthermore, the trigger lever 7 includes:

[0074] A connecting rod 701, one end of which is fixedly sleeved on the middle portion of the transmission rod 6, and an end of the connecting rod 701 away from the transmission rod 6 is provided with a mounting groove 7011;

[0075] The movable rod 702 is located on the side of the connecting rod 701 away from the transmission rod 6. A sliding rod 704 is fixed to the end of the movable rod 702 close to the transmission rod 6. The sliding rod 704 is movably inserted into the mounting groove 7011.

[0076] Adjusting bolt 705, the lower end thread of adjusting bolt 705 passes through the top wall of connecting rod 701 and is pressed against the upper surface of sliding rod 704. Figure 1 and attached Figure 3 The user can pull the movable rod 702 to make the sliding rod 704 slide a certain distance in the installation groove 7011, thereby adjusting the overall length of the trigger rod 7. After the length of the trigger rod 7 is changed, the time for the trigger rod 7 to contact the vertical rod above the feed trough of the farm can be adjusted when the trigger rod 7 moves with the rail carrier 1. That is, the longer the trigger rod 7 is, the longer the contact time of the trigger rod 7 with the vertical rod above the feed trough of the farm is when the speed of the rail carrier 1 is the same, thereby making the time for the unloading baffle 9 to deviate from the discharge port at the lower end of the feed storage bin 2 longer, thereby achieving the purpose of adjusting the feeding time, thereby changing the measurement of a single feeding.

[0077] Furthermore, the trigger rod 7 also includes a ball head 703, which is fixed to the end of the movable rod 702 away from the transmission rod 6. The ball head 703 is in contact with the sliding point of the vertical rod above the feed trough in the farm. Figure 3 The design of the ball head 703 allows the end of the movable rod 702 to produce point contact with the vertical rod above the feed trough in the farm, making the friction between the two smaller, thereby reducing the mutual wear between the end of the movable rod 702 and the vertical rod, thereby extending the service life of the trigger rod 7, reducing the replacement frequency of the movable rod 702 and the vertical rod above the feed trough in the farm, and reducing the maintenance rate and maintenance cost when using the precise metering feed distribution cart.

[0078] Furthermore, the reset member includes a reset torsion spring 8, which is movably mounted on the transmission rod 6. The upper and lower ends of the reset torsion spring 8 are respectively fixed to the bottom surface of the connecting rod 701 and the upper surface of the mounting block 201. Figure 1 and attached Figure 2 When the trigger rod 7 is separated from the vertical rod above the feed trough of the farm, the reset torsion spring 8 uses its own elasticity to drive the trigger rod 7 to reset, thereby driving the transmission rod 6 to reset, and finally achieving the purpose of fully resetting the unloading baffle 9 and the conical auger 502.

[0079] Furthermore, it also includes:

[0080] A first return spring 10, one end of which is fixed to one side of the connecting column connected to the blanking baffle 9, and the other end of the first return spring 10 is fixed to the lower end of the rail vehicle 1 through a fixing plate;

[0081] A second return spring 11, one end of the second return spring 11 is fixed to the side wall of one side of the rocker arm 12, and the other end of the second return spring 11 is fixed to the upper end surface of the feed storage bin 2 through a fixing plate;

[0082] Among them, the expansion and contraction paths of the first return spring 10 and the second return spring 11 are arc-shaped and have the same deflection direction as the fixed column and the rocker 12. From the above connection relationship, it can be seen that, combined with the attached Figure 2 and attached Figure 5 The first return spring 10 and the second return spring 11 respectively provide auxiliary elastic forces for the return of the unloading baffle 9 and the lifting wedge 13, so that the unloading baffle 9, the lifting wedge 13 and the transmission rod 6 can be returned faster and more stably, and the lifting wedge 13 has a greater lifting force, which can stably drive the lifting plate 14 to rise, and achieve the purpose of driving the conical auger 502 out of the discharge port of the feed storage bin 2;

[0083] The booster spring 16 is movably mounted on the guide rod 15. The upper and lower ends of the booster spring 16 are respectively fixed to the bottom surface of the lifting plate 14 and the upper surface of the feed storage bin 2. As can be seen from the above connection relationship, combined with the attached Figure 1 and attached Figure 5 The assist spring 16 can use its own elasticity to provide a rising prestress for the lifting plate 14, thereby assisting the lifting wedge 13 to lift the lifting plate 14, thereby better allowing the lifting plate 14 to rise.

[0084] Specifically, the working principle is as follows: first, feed for livestock or poultry is added to the feed storage bin 2, and then the rail carrier 1 and the servo motor 3 are started, so that the rail carrier 1 moves along the feeding track of the farm. During the movement, the servo motor 3 drives the transmission shaft 5 to rotate through the shaft sleeve 4, and then drives the homogenizing rod 501 and the conical auger 502 to rotate synchronously. The homogenizing rod 501 can disturb and homogenize the feed in the feed storage bin 2, which is conducive to uniform feeding of mixed feed of the same quality. The conical auger 502 is located above the discharge port of the feed storage bin 2 under normal conditions and does not play a role in assisting discharge. At this time, the discharge baffle 9 closes the discharge port at the lower end of the feed storage bin 2.

[0085] When the other end of the trigger rod 7 coincides with the position of the vertical rod above the feed trough in the farm during the movement, the trigger rod 7 is deflected and drives the transmission rod 6 to rotate. When the transmission rod 6 rotates, the unloading baffle 9 rotates with the transmission rod 6 and opens the discharge port at the lower end of the feed storage bin 2, thereby feeding feed into the feed trough. At the same time, the transmission rod 6 drives the lifting wedge 13 to rotate a certain angle through the rocker arm 12, so that the lifting wedge 13 loses its lifting effect on the lifting plate 14. At this time, the transmission shaft 5, the homogenizing rod 501 and the conical auger 502 descend under the action of their own gravity, and the conical auger 502 enters the discharge port at the lower end of the feed storage bin 2, which plays a role in assisting unloading.

[0086] The feed outlet of the feed storage bin 2 is fixed to the feed trough of the farm, and the other end of the trigger rod 7 is separated from the vertical rod above the feed trough of the farm. At this time, the trigger rod 7 is reset under the elastic force of the reset torsion spring 8 and the transmission rod 6 is reset at the same time, so that the discharge baffle 9 is reset again to close the feed outlet at the lower end of the feed storage bin 2, and the lifting wedge 13 is in contact with the lower end of the lifting plate 14 again through the arc guide surface 1301 and drives the lifting plate 14 to rise, thereby lifting the conical auger 502 and completing the feed feeding operation. Since the discharge speed of the feed storage bin 2 is fixed, the opening time of the feed storage bin 2 can be adjusted by adjusting the travel speed of the rail carrier 1, so as to achieve the purpose of quantitative feed delivery, and the measurement is more accurate. The mechanical triggering method is not affected by the external magnetic field, current and voltage, and is more stable and reliable during operation.

[0087] In addition, the user can pull the movable rod 702 to make the sliding rod 704 slide a certain distance in the installation groove 7011, thereby adjusting the overall length of the trigger rod 7. After the length of the trigger rod 7 is changed, the time for the trigger rod 7 to contact the vertical rod above the feed trough of the farm can be adjusted when the trigger rod 7 moves with the rail vehicle 1. That is, the longer the trigger rod 7 is, the longer the contact time of the trigger rod 7 with the vertical rod above the feed trough of the farm is when the speed of the rail vehicle 1 is the same, thereby making the time for the unloading baffle 9 to deviate from the discharge port at the lower end of the feed storage bin 2 longer, thereby achieving the purpose of adjusting the feeding time, thereby changing the measurement of a single feeding;

[0088] The use of this precise metering feed distribution cart eliminates the need for a variety of sensors, control devices, and control systems, thereby achieving the goal of reducing equipment costs and being more suitable for the comprehensive promotion of this precise metering feed distribution cart.
