Description

Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, and specifically relates to an unmanned feed delivery vehicle. Background Technology

[0002] When feeding livestock in a farm, feed is spread using a feed spreader. The spreader is driven manually along one side of the pen, and the feed is spread into the troughs on that side of the pen.

[0003] Patent application CN219812853U discloses an unmanned feed distribution vehicle, relating to the field of pasture feeding technology. It includes a transverse feed cylinder fixed to the top of the unmanned vehicle body via an n-shaped support frame. A feed hopper is fixed at the feed inlet at the top center of the transverse feed cylinder, and an inclined feed distribution pipe is fixed at the discharge outlet on one side of the bottom of the transverse feed cylinder. The inclined feed distribution pipe is connected to the interior of the transverse feed cylinder. This unmanned feed distribution vehicle differs from existing technologies by utilizing an intermittent pushing mechanism. By activating a dual-axis motor and cooperating with multiple components, the pushing cylinder reciprocates inside the transverse feed cylinder. Combined with two baffles, feed from the feed hopper intermittently enters the pushing cylinder. Furthermore, the inclined feed distribution pipe allows the unmanned vehicle body to move while performing intermittent feeding operations, ensuring even feed distribution and avoiding disruption to cattle and sheep feeding operations.

[0004] However, the aforementioned comparative documents show that when feeding feed, the feeding port cannot be adjusted according to the height of the feed trough. When the position of the feed trough changes or the feed troughs are distributed in multiple rows, it cannot adapt to the changes in the position and number of feed troughs in real time, resulting in a limited range of applicability. Utility Model Content

[0005] The purpose of this invention is to provide an unmanned feed delivery vehicle to solve the technical problem in the background art that the feeding port cannot adapt to changes in real time according to the position and number of feed troughs, resulting in a limited range of applications.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An unmanned feed dispensing vehicle includes: a chassis and a frame; a frame structure is fixed on the chassis, and two sets of parallel axles are rotatably coupled to the chassis via bearings. A wheel is fixed on each side of the axles. A servo motor is fixed on the chassis, and the servo motor provides rotational power to the axles through direct or indirect transmission. A feed hopper is fixed on the top of the frame, and a quantitative feeding mechanism is provided below the feed hopper. The main body of the quantitative feeding mechanism is a horizontal cylindrical material pipe with closed ends. An inlet is opened at the top of the material pipe, which is connected to the lower end of the feed hopper. An outlet is opened at the top of the material pipe, and an outlet pipe is connected to the outlet pipe via a guide pipe. The outlet pipe is directly or indirectly mounted on the chassis or frame. A propeller is concentrically coupled to the material pipe, and a feeding motor is fixed on the frame to provide rotational power to the propeller.

[0008] Furthermore: In order to make the discharge pipe applicable to feed troughs of different heights, the discharge pipe is mounted on the chassis with a height adjustment mechanism. The main body of the height adjustment mechanism includes: a base and a fixing rod; wherein the fixing rod is fixed to the chassis in an inclined state by the base, and a hinge seat is hinged to the top of the fixing rod. The hinge seat is fixed to the fixed end of a telescopic pole. The telescopic end of the telescopic pole is fixed to the discharge pipe. The bottom of the discharge pipe is inclined away from the telescopic pole. An electric push rod is provided between the base and the hinge seat. The two ends of the electric push rod are respectively hinged to the base and the hinge seat.

[0009] Furthermore, in order to improve the stability of the chassis movement, a driven gear is concentrically fixed on the axle, and a drive gear is fixed on the output shaft of the servo motor; the drive gear and the driven gear mesh with each other, or the drive gear and the driven gear mesh indirectly through a gear reducer.

[0010] Furthermore, in order to stop the feeding vehicle in real time after the chassis has finished moving, a brake disc is fixed on the axle, and a brake is provided on the chassis to brake the brake disc.

[0011] Furthermore, in order to increase the torque of the propeller during operation and improve its starting smoothness under full load, a reducer is also fixed on the frame. The output shaft of the reducer is coaxially fixed with the propeller, and the input shaft of the reducer is coaxially fixed with the output shaft of the feed motor.

[0012] Furthermore, in order to enable the guide pipe to adapt to the position adjustment of the discharge pipe, the guide pipe is made of steel wire hose.

[0013] Furthermore, to prevent the feeding vehicle from tipping over when the feed hopper is full, several counterweights are fixed on the chassis.

[0014] Furthermore: In order to enable this application to also transport livestock supplies such as medicines, manure, and grain, a feed bin is embedded in the frame, and the feed bin has an inner cavity for receiving.

[0015] Furthermore: In order for the feed guide pipe to smoothly guide the feed from the outlet to the feed pipe by gravity, the maximum height of the feed pipe must be lower than the height of the outlet.

[0016] In summary, this utility model has the following beneficial effects:

[0017] ① It can adapt to changes in the location and number of feed troughs: With the establishment of a height adjustment mechanism, when the height of the feed trough changes, or when dealing with a feeding environment with feed troughs of multiple heights, the height of the discharge pipe needs to be adjusted. When adjusting the height of the discharge pipe, the electric push rod is activated by an external controller to extend and retract. According to the lever principle, the electric push rod will drive the telescopic rod and the hinge seat to deflect around the top of the fixed rod, thereby changing the height of the discharge pipe fixed at the end of the telescopic rod, thus adjusting the height of the discharge pipe. Since the horizontal distance between the discharge pipe and the feed trough also changes after the height of the discharge pipe is adjusted in the above way, causing the feed to not enter the feed trough, after the height of the discharge pipe is adjusted, it is also necessary to control the telescopic rod to extend and retract through an external controller to adjust the horizontal distance between the discharge pipe and the feed trough, so that the feed from the adjusted height discharge pipe can smoothly enter the feed trough.

[0018] ② The feeding amount can be precisely adjusted: By setting up a quantitative feeding mechanism, the feeding motor is powered on and starts to work. The feeding motor drives the propeller to rotate. The feed in the feed hopper enters the propeller in the feed pipe from the feed inlet. When the propeller rotates, it will drive the feed in the spiral direction. Therefore, by specifying the rotation direction of the motor, the propeller can be rotated in the direction from the feed inlet to the feed outlet. When the feed reaches the feed outlet, it will enter the guide pipe under the action of gravity and the extrusion force provided by the propeller. Then, it enters the discharge pipe from the guide pipe and discharges the feed into the feed trough to complete the feeding. Based on the above principle, the rotation speed of the feeding motor can be adjusted, thereby adjusting the amount of feed transported by the propeller, and thus the feeding amount can be precisely adjusted.

[0019] ③ Automated feeding is possible: An external automated controller can be connected to control the movement of the brake, telescopic pole, electric push rod, feeding motor, and servo motor. The automated controller can be programmed with appropriate parameters such as the actual length, height, and number of feed troughs in the breeding farm, as well as the feeding time, to achieve unmanned automatic feeding of the breeding vehicle and complete the automated feeding of feed.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0027] Please see Figures 1-5 The present invention provides the following technical solution:

[0028] An unmanned feed delivery vehicle includes: a chassis 1 and a frame 2; a frame structure frame 2 is fixed on the chassis 1, and two sets of parallel axles 81 are rotatably coupled to the chassis 1 by bearings. A wheel 8 is fixed on each side of the axle 81. A servo motor 10 is fixed on the chassis 1, and the servo motor 10 provides rotational power to the axles 81 through direct or indirect transmission. A feed hopper 3 is fixed on the top of the frame 2, and a quantitative feeding mechanism 4 is provided below the feed hopper 3. The main body of the quantitative feeding mechanism 4 is a feed pipe 41 with a horizontal cylindrical structure closed at both ends. A feed inlet 42 is opened at the top of the feed pipe 41 and is connected to the lower end of the feed hopper 3. A discharge outlet 43 is opened at the top of the feed pipe 41 and is connected to a discharge pipe 6 by a guide pipe 7. The discharge pipe 6 is directly or indirectly installed on the chassis 1 or the frame 2. A propeller 44 is concentrically coupled to the feed pipe 41, and a feed motor 45 is fixed on the frame 2 to provide rotational power to the propeller 44.

[0029] The discharge pipe 6 is mounted on the chassis 1 using a height adjustment mechanism 5. The main body of the height adjustment mechanism 5 includes a base 51 and a fixing rod 52. The fixing rod 52 is fixed to the chassis 1 at an angle using the base 51. A hinge seat 55 is hinged to the top of the fixing rod 52. The hinge seat 55 is fixed to the fixed end of a telescopic electric rod 53. The telescopic end of the telescopic electric rod 53 is used to fix the discharge pipe 6. The bottom of the discharge pipe 6 is inclined away from the telescopic electric rod 53. An electric push rod 54 is provided between the base 51 and the hinge seat 55. The two ends of the electric push rod 54 are respectively hinged to the base 51 and the hinge seat 55.

[0030] A driven gear 82 is concentrically fixed on the axle 81, and a drive gear is fixed on the output shaft of the servo motor 10; the drive gear and the driven gear 82 mesh with each other, or the drive gear and the driven gear 82 mesh indirectly through a gear reducer.

[0031] A brake disc 83 is fixed on the axle 81, and a brake is provided on the chassis 1 for braking the brake disc 83 (the brake is a direct application of this application and is not within the scope of protection of this application, so its specific structure description is omitted. Its specific structure can be found in CN101846148A; at the same time, because it is a direct application of this application, the brake is not shown in the figure).

[0032] A speed reducer 46 is also fixed on the frame 2. The output shaft of the speed reducer 46 is coaxially fixed with the propeller 44, and the input shaft of the speed reducer 46 is coaxially fixed with the output shaft of the feeding motor 45.

[0033] The feed tube 7 is made of steel wire hose.

[0034] Several counterweights 11 are fixed on the chassis 1.

[0035] A material bin 9 is embedded in the frame 2, and the material bin 9 has an inner cavity for receiving.

[0036] The maximum height of the discharge pipe 6 must be lower than the height of the discharge port 43.

[0037] Brief description of usage:

[0038] When in use, fill the feed hopper 3 with feed, power on the servo motor 10 to make it work, and the drive gear at the end of the servo motor 10 directly or indirectly drives the driven gear 82 to rotate. When the driven gear 82 rotates, it drives the wheel 8 to rotate through the wheel axle 81. The wheel 8 drives the entire device to move, so that the entire feeding vehicle moves along the direction of the feed trough 12. If necessary, a guide rail can be set on the side of the feed trough 12 to provide movement guidance for the wheel 8.

[0039] When the feeding vehicle moves, the feeding motor 45 is powered on and starts working. The feeding motor 45 drives the propeller 44 to rotate. The feed in the feed hopper 3 enters the propeller 44 in the feed pipe 41 from the feed inlet 42. When the propeller 44 rotates, it will drive the feed in it to move in the spiral direction. Therefore, by specifying the rotation direction of the feeding motor 45, the propeller 44 can be made to rotate in the direction from the feed inlet 42 to the discharge outlet 43. When the feed reaches the discharge outlet 43, it will enter the guide pipe 7 under the action of gravity and the squeezing force provided by the propeller 44, and then enter the discharge pipe 6 from the guide pipe 7. The discharge pipe 6 discharges the feed into the feed trough 12 to complete the feeding.

[0040] When the height of the feed trough 12 changes, or when dealing with a feeding environment with multiple height levels in the feed trough 12, the height of the discharge pipe 6 needs to be adjusted. When adjusting the height of the discharge pipe 6, the electric push rod 54 is activated by an external controller to extend and retract. According to the lever principle, the electric push rod 54 will drive the telescopic rod 53 and the hinge seat 55 to deflect around the top of the fixed rod 52. As a result, the height of the discharge pipe 6 fixed at the end of the telescopic rod 53 will change, thereby adjusting the height of the discharge pipe 6. Since the horizontal distance between the discharge pipe 6 and the feed trough 12 also changes after the height of the discharge pipe 6 is adjusted in the above way, the feed cannot enter the feed trough 12. Therefore, after the height of the discharge pipe 6 is adjusted, the telescopic rod 53 needs to be extended and retracted by an external controller to adjust the horizontal distance between the discharge pipe 6 and the feed trough 12, so that the feed from the adjusted discharge pipe 6 can smoothly enter the feed trough 12.

[0041] After the feeding vehicle finishes feeding, the brake disc 83 can be braked by the brake device to fix the position of the feeding vehicle. At the same time, the inner cavity of the feed bin 9 can also transport breeding materials such as medicine, manure, and grain.

[0042] The aforementioned brake, telescopic pole 53, electric push rod 54, feeding motor 45, and servo motor 10 can all rely on an external automated controller to achieve motion control. The automated controller can program a suitable program based on the actual length, height, number, and feeding time of the feed trough 12 in the breeding farm to achieve unmanned automatic feeding of the breeding vehicle and complete the automated feeding of feed.

[0043] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
