Description

Technical Field

[0001] This utility model relates to the field of forage harvesters, specifically a combined forage harvester. Background Technology

[0002] A hay harvester is a type of livestock machinery primarily used to cut fresh forage from pastures and process it into hay for feed. Hay harvesters significantly reduce drying time and ensure uniform drying, thus preserving the aroma and nutritional value of the forage. Furthermore, modern hay harvesters are highly automated and intelligent, saving considerable labor and time costs, making them an indispensable tool in livestock production.

[0003] For example, authorization announcement number CN207135533U discloses a combined forage harvester, including a drive vehicle, a forage cutting plate, and a storage box. The drive vehicle consists of a cab located on top of the drive vehicle and a chassis located at the bottom of the cab. Both ends of the chassis side are equipped with symmetrically arranged coarse-patterned wheels. A hanging plate is provided on one side of the top of the chassis, and a connecting plate is provided at the bottom of the hanging plate. A cylindrical connecting shaft is provided at the middle position along the width direction of the hanging plate. The connecting shaft passes through the hanging plate and the connecting plate, and the connecting plate and the hanging plate are movably connected through the connecting shaft. A connecting post is provided at the bottom of the connecting plate. This combined forage harvester is suitable for grassland forage harvesting operations. It has complete functions and can automatically complete harvesting, collection, and transportation tasks. The harvesting operation has a high degree of completion. It is flexible and easy to use, and its simple structure can reduce labor intensity and reduce manpower and material consumption, and has broad application prospects.

[0004] However, the above-mentioned technology only uses a shovel to shovel the forage into the conveying trough, and the forage is squeezed into the storage box in the conveying trough, which is inefficient. At the same time, the conveying trough can only transport the forage to the bottom of the storage box and cannot accumulate the forage at the top of the storage box, resulting in low utilization of the internal space of the storage box. Therefore, the market urgently needs to develop a combined forage harvester to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a combined forage harvester to solve the problems mentioned in the background art, such as the low efficiency of the method of forage entering the storage box through the extrusion action in the conveying trough and the low utilization rate of the internal space of the storage box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined forage harvester, including an inclined conveyor belt, with multiple conical protrusions arrayed on the outer end face of the inclined conveyor belt, conveyor belt side plates connected to both sides of the inclined conveyor belt, multiple triangular shovels connected at equal intervals to the lower end of the front end of the inclined conveyor belt, a support frame fixedly connected to the lower ends of the two conveyor belt side plates, a storage box connected to the rear end of the support frame, and an inclined guide plate fixedly connected to the upper end of the front end face of the storage box.

[0007] Preferably, both the front and rear ends of the inclined conveyor belt are connected to conveyor belt shafts, and both sides of the two conveyor belt shafts are rotatably connected to two conveyor belt side plates respectively. A conveyor belt drive device for driving the inclined conveyor belt to rotate is fixedly connected to the rear end of the outer side of one of the conveyor belt side plates, and a baffle plate is fixedly connected to the upper end of both conveyor belt side plates.

[0008] Preferably, the multiple triangular shovels are fixedly connected together by a round rod, and the rear ends of the two triangular shovels on both sides are fixedly connected to the front ends of the two conveyor belt side plates respectively.

[0009] Preferably, the front and rear ends of the lower ends of both sides of the support frame are rotatably connected to the first wheels, and the upper and lower ends of the middle of the rear ends of both sides of the support frame are fixedly connected to the connecting plates.

[0010] Preferably, the storage box has crossbeams fixedly connected to both the front and rear ends of the lower end face, and second wheels are rotatably connected to both sides of the two crossbeams.

[0011] Preferably, a connecting rod is fixedly connected to the middle of the front end of each of the two end faces of the storage box, and the front ends of the two connecting rods are respectively inserted between the two connecting plates on both sides of the support frame.

[0012] Preferably, each of the connecting plates has a first insertion hole in the middle, and the two connecting rods have a second insertion hole at their front ends. The connecting rods are locked to the two connecting plates by an L-shaped pin passing through the first and second insertion holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the design of the inclined conveyor belt, combined with the conical protrusion, achieves efficient transportation of forage. The inclined conveyor belt can not only scoop up the forage from the ground, but also use its own inclination angle and the gripping force of the conical protrusion to quickly and continuously transport the forage to the storage box. Compared with the traditional method of sending the forage into the storage box by squeezing, this design greatly improves the transportation efficiency.

[0015] (2) In this utility model, the forage enters from the top of the storage box through the inclined guide plate, so that the forage can be evenly distributed inside the storage box, thereby improving the space utilization rate inside the storage box.

[0016] (3) In this utility model, when the storage box is full of hay and needs to be unloaded, you only need to pull out two L-shaped pins to separate the storage box from the support frame. Since the storage box is equipped with a second wheel at the bottom, it can be easily moved to a suitable position for unloading. The operation is simple and quick. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a combined forage harvester, comprising an inclined conveyor belt 1, with multiple conical protrusions 102 arrayed on the outer end face of the inclined conveyor belt 1. Conveyor belt side plates 103 are connected to both sides of the inclined conveyor belt 1. Conveyor belt shafts 101 are connected to both the front and rear ends of the inclined conveyor belt 1. The two conveyor belt shafts 101 are rotatably connected to the two conveyor belt side plates 103 on both sides. A conveyor belt drive device 104 for driving the inclined conveyor belt 1 to rotate is fixedly connected to the rear end of the outer side of one conveyor belt side plate 103. A baffle plate 3 is fixedly connected to the upper end of both conveyor belt side plates 103. Multiple triangular shovels 2 are evenly spaced connected to the lower end of the front end of the inclined conveyor belt 1. The multiple triangular shovels 2 are fixedly connected together by a round rod 201. The rear ends of the two triangular shovels 2 on both sides are fixedly connected to the front ends of the two conveyor belt side plates 103, and the lower ends of the two conveyor belt side plates 103 are fixedly connected together. The device includes a support frame 301, with a storage box 4 connected to its rear end. An inclined guide plate 401 is fixedly connected to the upper end of the front face of the storage box 4. The agricultural machinery is connected to the two conveyor belt side plates 103 via a traction rod, allowing the agricultural machinery to move the entire device. When the device moves, multiple triangular shovels 2 scoop up the harvested material from the ground, allowing the forage to move through the upper end of the triangular shovels 2 and enter the front end of the inclined conveyor belt 1. The conveyor belt drive device 104 drives the inclined conveyor belt 1 to rotate. When the inclined conveyor belt 1 rotates, a conical protrusion 102 inserts into the forage, thereby driving the forage to follow the inclined conveyor belt 1 upward. After being transported to the upper end by the inclined conveyor belt 1, the forage falls into the upper end of the inclined guide plate 401 and is guided by the inclined guide plate 401 into the storage box 4 for accumulation, improving the forage collection efficiency. At the same time, the method of allowing the forage to enter from the upper end of the storage box 4 improves the utilization rate of the internal space of the storage box 4.

[0024] Please see Figure 1 , Figure 2 and Figure 4The support frame 301 has first wheels 302 rotatably connected to both ends of its lower sides, allowing it to move via multiple first wheels 302. Connecting plates 303 are fixedly connected to the upper and lower ends of the rear ends of both sides of the support frame 301. Crossbeams 402 are fixedly connected to the front and rear ends of the lower end face of the storage box 4. Second wheels 403 are rotatably connected to both sides of the two crossbeams 402, allowing the storage box 4 to move via the second wheels 403. Connecting rods 404 are fixedly connected to the middle of the front ends of both sides of the storage box 4, with the front ends of the two connecting rods 404 respectively inserted into… Between the two connecting plates 303 on both sides of the support frame 301, each connecting plate 303 has a first insertion hole 304 in the middle, and the front ends of the two connecting rods 404 are provided with second insertion holes 405. The connecting rods 404 and the two connecting plates 303 are locked together by L-shaped pins 5 passing through the first insertion hole 304 and the second insertion hole 405. When the support frame 301 moves, the storage box 4 is moved by pulling the connecting rods 404. When it is necessary to unload the storage box 4, the storage box 4 can be separated from the support frame 301 by pulling out the two L-shaped pins 5, so that the storage box 4 can be moved and unloaded independently.

[0025] Working Principle: In use, the agricultural machinery is connected to the support frame 301 via a traction rod. After starting the machinery, the entire device moves along the ground under its traction. During the movement, the front ends of multiple triangular shovels 2 scoop up the forage on the ground, which is then transported to the front end of the inclined conveyor belt 1. At this time, the conveyor belt drive device 104 is activated, driving the inclined conveyor belt 1 to rotate. The conical protrusions 102 on the surface of the inclined conveyor belt 1 effectively grasp the forage and transport it upwards along the path of the inclined conveyor belt 1. After the forage reaches the top of the inclined conveyor belt 1, it falls naturally onto the inclined guide plate 401 due to gravity and slides into the storage box 4 along the inclined direction of the guide plate 401, achieving efficient collection of forage. In addition, when the storage box 4 is full of hay and needs to be unloaded, simply pull out the two L-shaped pins 5 to separate the storage box 4 from the support frame 301. Since the storage box 4 is equipped with a second wheel 403 at the bottom, it can be easily moved to a suitable position for unloading, making the operation simple and quick.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
