Description

Technical Field

[0001] This utility model relates to the field of feed dispensing equipment technology, and in particular to a dispensing device for a feed dispensing vehicle. Background Technology

[0002] In beef cattle farms, a large amount of forage needs to be fed each time. Forage distribution involves two stages: transportation and distribution. Typically, tricycles are used for transportation, and manual distribution is employed. There are also towed transport and distribution vehicles, but these generally have small capacities and low distribution efficiency. Modern beef cattle farms use specialized feed distribution vehicles to improve efficiency and reduce worker workload. These vehicles have dedicated feed distribution equipment mounted on the chassis of a truck, offering large capacity and high automatic distribution efficiency. For example, patent CN221930976U – a feed distribution vehicle for cattle farms – features two vertical spirals in the feed hopper. The spirals rotate to throw the feed (chopped forage less than 20cm in length) out of the hopper, achieving the desired distribution effect. However, this method has the following drawbacks: 1. The feed hopper is too small, and the two spirals occupy too much space, resulting in too little feed being transported at a time, requiring frequent loading and unloading; 2. When the feed is insufficient, the lack of pulling between the feed particles means that the feed between the two spirals cannot be effectively utilized and will remain in the feed hopper. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a feeding device for a feed delivery vehicle. The device is made of bent thin steel plates riveted and welded into a longitudinally columnar hopper. Two parallel horizontal spirals are provided at the bottom of the hopper, and a horizontal conveyor belt is provided at the discharge port at the bottom end of the hopper, thereby improving the feeding and dispensing capacity of the hopper.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a feeding device for a feed feeding vehicle, including a hopper with an open top, the open top being a feed inlet, and two parallel horizontal spirals driven by a motor installed at the bottom of the hopper. The two ends of the horizontal spirals are rotatably connected to the front and rear wall panels of the hopper. The spiral directions of the two horizontal spirals are opposite, and their rotation directions are also opposite. A discharge port is installed at the bottom of the tail end of the hopper, and a left-right horizontal conveyor belt is installed below the discharge port.

[0005] Preferably, the cross-section of the hopper is consistent from front to back, and the hopper is formed by welding front, back, left and right wall panels.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

[0018] like Figures 1-7 As shown, a feeding device for a feed delivery vehicle in this embodiment includes a hopper 1 with an open top, which is a feed inlet 11. Two parallel horizontal spirals 2 driven by a motor are provided at the bottom of the hopper 1. The two ends of the horizontal spirals 2 are rotatably connected to the front and rear wall panels of the hopper 1. The spiral directions of the two horizontal spirals 2 are opposite, and their rotation directions are also opposite. A discharge port 12 is provided at the bottom of the tail end of the hopper 1. A horizontally arranged conveyor belt 3 is provided below the horizontal spirals 2.

[0019] The feed hopper 1 described in this embodiment is specifically designed for feed delivery vehicles, or for hay delivery vehicles used in cattle farms. The feed hopper 1 is constructed by first welding and riveting thin steel plates together to form front, rear, left, and right side panels, which are then welded together to form a structure resistant to vibration. The bottom of the feed hopper 1 is formed by bending the side panels into two continuous arc-shaped cavities, with the horizontal screw 2 positioned within these cavities. During operation, the two horizontal screws 2 push the hay towards the rear of the feed hopper 1. The hay falls onto the conveyor belt and is then ejected from the side of the delivery vehicle.

[0020] The horizontal spiral 2 includes a rotating shaft 21 and a spiral blade 22. The spiral blade 22 extends along the rotating shaft 21 to the discharge port 12 near the front end of the hopper 1. At least two material guide plates 23 are provided in the section of the rotating shaft 21 above the conveyor belt 3. The material guide plates 23 are distributed along the axial direction of the rotating shaft 21. Each material guide plate 23 is spaced 100-200mm apart from the previous material guide plate 23 and rotates 90-180° around the rotating shaft 21.

[0021] The feed hopper 1 is mounted on the frame 4 of the delivery vehicle. Specifically, two brackets 41 are fixed to the bottom of the feed hopper 1, and a mounting seat 42 is provided at each end of the bracket 41. A crossbeam 43 is fixed to the frame 4, and the mounting seat 42 and the crossbeam 43 are connected by a weight sensing device 44. The weight sensing device 44 is a resistance strain gauge sensor, which can automatically weigh the feed hopper 1 and the forage inside it.

[0022] The front wall panel of the hopper 1 is equipped with two motor-driven reducers 5, and the output shafts of the reducers 5 are fixedly connected to the horizontal screw 2 via couplings. Thus, the two horizontal screws 2 are driven by independent power.

[0023] In addition, the feed delivery vehicle in this embodiment is driven by a new energy battery, that is, a battery is set on the frame 4 to power the horizontal screw 2 and the conveyor belt 3; for this purpose, a controller 51 is provided, which is installed on the mounting bracket on the front wall of the hopper 1, and the frame 4 is provided with a radiator 52 to cool the controller 51.

[0024] The conveyor belt 3 can throw hay onto both sides of the delivery vehicle by rotating the motor in both directions. Its specific structure is as follows: the conveyor belt 3 includes two cage pulleys 31, one of which is driven by a motor, and the other is connected to a bearing seat with a tensioning device. A belt 32 is sleeved between the two cage pulleys 31, and a support frame 33 is provided below the upper belt 32.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and for the convenience of describing the technical solution, the front, back, left, right, top, middle, and bottom orientations are based on the accompanying drawings and are not a limitation on the protection scope of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
