Description

Technical Field

[0001] This utility model belongs to the field of sorghum harvesting technology, specifically relating to a sorghum stalk and ear integrated feeding harvester. Background Technology

[0002] The sorghum stalk and ear integrated feeding harvester is a commonly used piece of equipment for sorghum harvesting. The sorghum is fed into the equipment for threshing by the reel and screw feeder set in the harvester's cutting platform.

[0003] In existing technology, standing sorghum is pushed towards the cutter by a reel, and the cut sorghum heads are then fed to a screw feeder. During harvesting, the upright sorghum is violently pushed backward from the bottom of the sorghum stalks by the high-speed rotating reel. Due to the inertia of the top sorghum heads and the drag of the reel, the sorghum heads will swing dramatically, causing them to collide and slam against the metal parts of the cutter head, such as the cutter head panel and side supports. The grains at the top of the sorghum heads have weak bonding at maturity, and this strong impact can easily cause a large number of grains to fall off the heads and onto the field, resulting in yield loss. Utility Model Content

[0004] This invention provides a sorghum stalk and ear integrated feeding harvester, which reduces the impact on sorghum ears during the feeding process and reduces the loss of sorghum grains.

[0005] This utility model provides the following technical solution: a sorghum stalk and ear integrated feeding harvester, including a sorghum harvester body and a harvester cutting platform. Two symmetrically distributed upper curved arc plates are provided on one side of the sorghum harvester body. A number of spaced-apart ear stalk inclined pressure rods are rotatably connected between the two upper curved arc plates. The vertical projections of the ear stalk inclined pressure rods all extend out of the front end of the harvester cutting platform. A front extension bracket is rotatably connected to one end of each of the two upper curved arc plates. The front extension bracket is fixedly connected to the top of the harvester cutting platform.

[0006] The upper curved plate has several mounting holes on its side wall, and each of the mounting holes corresponds to a position of a number of the spikelet stalk inclined pressure rods.

[0007] The upper curved plate has a positioning pin hole on its side wall, and a limit ring is fixedly connected to the side wall of the upper curved plate.

[0008] The stalk-sloping pressure bar has detachable connectors at both ends. The connectors are fitted with bearings on their outer sides and are threadedly connected to the stalk-sloping pressure bar through the bearings and the mounting holes.

[0009] Among them, several of the above-mentioned stalk inclined pressure rods are fitted with an outer shell.

[0010] The front extension bracket has a connecting groove block fixedly connected to one end, and the front extension bracket is rotatably connected to the upper curved plate through the connecting groove block. A positioning pin is inserted into the side wall of the connecting groove block.

[0011] The sorghum harvester body has a fixed ring fixedly connected to one side, and the fixed ring corresponds to the position of the limiting ring.

[0012] The beneficial effects of this utility model are as follows: by using the upper curved plate and the front extension bracket to extend the stalk inclined pressure bar towards the front of the harvester's cutter table, during the forward movement of the sorghum harvester, the stalk inclined pressure bar can contact the sorghum to be harvested before the harvester's cutter table, and pre-press the sorghum downwards and tilts it, so that the sorghum ears can be smoothly and smoothly fed into the spiral feeder of the harvester's cutter table in an inclined posture, avoiding the sorghum ears being quickly pulled by the reel in a standing state and being slammed onto the cutter table, reducing the impact on the sorghum ears during the feeding process, and reducing the loss of sorghum grains.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0019] Please see Figures 1-4The present invention provides the following technical solution: a sorghum stalk and ear integrated feeding harvester, including a sorghum harvester body 1 and a harvester cutting platform 11. Two symmetrically distributed upper curved arc plates 2 are provided on one side of the sorghum harvester body 1. Several ear stalk inclined pressure rods 3 are rotatably connected between the two upper curved arc plates 2. The vertical projections of the several ear stalk inclined pressure rods 3 extend out of the front end of the harvester cutting platform 11. One end of each of the two upper curved arc plates 2 is rotatably connected to a front extension bracket 4. The front extension bracket 4 is fixedly connected to the top of the harvester cutting platform 11.

[0020] In this implementation plan: When harvesting sorghum stalks and ears as a whole, the upper curved plate 2 and the stalk-slope inclined pressure bar 3 are adjusted to the front of the harvester's header 11. During the harvesting process, the upper curved plate 2 and the stalk-slope inclined pressure bar 3 move forward with the sorghum harvester body 1. The stalk-slope inclined pressure bar 3 will contact the sorghum stalks before the harvester's header 11, and in the subsequent movement, it will slowly squeeze the sorghum into a tilted state, while keeping the sorghum ears in contact with the stalk-slope inclined pressure bar 3. When the sorghum stalks are pulled by the reel of the harvester's header 11, the sorghum is dragged in an inclined posture to the position of the screw feeder. The sorghum feeding process is decomposed into two parts: pressing down from a standing posture to an inclined state and tilting and dragging, changing the posture of the sorghum ears before being pulled by the reel. With the stalk-slanting pressure bar 3 used to limit the sorghum ears during feeding, the sorghum ears can be fed more smoothly into the screw feeder. Compared with the existing technology where the upright sorghum is directly dragged by the reel, this can effectively avoid the rapid swinging caused by the sorghum ears being dragged while upright, thereby preventing the sorghum from hitting the metal structure of the harvester's header 11, reducing the impact on the sorghum ears during feeding, and reducing the loss of grains. The multiple 3-stalk-slanting pressure bars can adapt to sorghum ears of different heights and can continuously limit the sorghum ears of tall plants, preventing the sorghum ears from hitting the header structure. The arc shape of the 3-stalk-slanting pressure bar can slide more smoothly relative to the sorghum ears, avoiding the obstruction of sharp edges that cause grain loss.

[0021] The upper curved plate 2 has several mounting holes 21 on its side wall, and the mounting holes 21 correspond to the positions of several stalk inclined pressure rods 3 respectively. The mounting holes 21 facilitate the connection between the stalk inclined pressure rods 3 and the upper curved plate 2, and the mounting holes 21 serve to make way and position the rods.

[0022] The upper curved plate 2 has a positioning pin hole 22 on its side wall, and a limit ring 23 is fixedly connected to the side wall of the upper curved plate 2. The positioning pin hole 22 is opened at the position corresponding to the upper curved plate 2 and the connecting groove block 41, and is used for positioning pin rod 42 to be inserted and positioned.

[0023] Both ends of the stalk-sloping pressure bar 3 are detachably connected to connectors 31. A bearing 32 is fitted on the outside of the connector 31. The connector 31 passes through the bearing 32 and the mounting hole 21 and is threadedly connected to the stalk-sloping pressure bar 3. When installing the stalk-sloping pressure bar 3, the stalk-sloping pressure bar 3 is placed in the position corresponding to the mounting hole 21. Then, the bearing 32 is fitted on the outside of the connector 31, and the connector 31 and the bearing 32 are threaded through the mounting hole 21 and connected to the stalk-sloping pressure bar 3. The above operation is repeated to install the connector 31 on the other side of the stalk-sloping pressure bar 3. The stalk-sloping pressure bar 3 can be installed on the two upper curved plates 2, and the relative rotation of the connector 31 and the bearing 32 can realize the relative rotation of the stalk-sloping pressure bar 3 and the upper curved plate 2.

[0024] Several stalk-slanting pressure rods 3 are fitted with outer shells 33 on their outer walls. By setting the outer shells 33, the stalk-slanting pressure rods 3 can be replaced to contact the plant. When the plant is worn or scratched over a long period of time, the stalk-slanting pressure rods 3 can be removed and only the outer shells 33 need to be replaced, thus reducing the cost of replacing parts.

[0025] One end of the front extension bracket 4 is fixedly connected to a connecting groove block 41. The front extension bracket 4 is rotatably connected to the upper curved plate 2 through the connecting groove block 41. A positioning pin 42 is inserted into the side wall of the connecting groove block 41. The upper curved plate 2 and the connecting groove block 41 are connected by a shaft to realize the rotatable connection between the upper curved plate 2 and the connecting groove block 41. The positioning pin 42 passes through the connecting groove block 41 and is inserted into the positioning pin hole 22 to position the upper curved plate 2. The other end of the positioning pin 42 can be fixed by a nut to prevent the positioning pin 42 from falling off the connecting groove block 41.

[0026] A fixing ring 5 is fixedly connected to one side of the sorghum harvester body 1, and the fixing ring 5 corresponds to the position of the limiting ring 23. When the equipment is loaded for transportation or traveling on the road, the positioning pin 42 can be removed, the upper curved plate 2 can be flipped toward the driver's position, and then the chain can be used to tighten the upper curved plate 2 by passing through the limiting ring 23 and the fixing ring 5, thereby reducing the overall length of the vehicle body and making transportation or driving more convenient.

[0027] The working principle and usage process of this utility model: The upper curved plate 2 and the stalk inclined pressure rod 3 are adjusted to the front side of the harvester's cutting platform 11. During the harvesting process, the upper curved plate 2 and the stalk inclined pressure rod 3 move forward with the sorghum harvester body 1. The stalk inclined pressure rod 3 will contact the sorghum stalks before the harvester's cutting platform 11, and in the subsequent movement, it will slowly squeeze the sorghum to a tilted state, while keeping the sorghum ears in contact with the stalk inclined pressure rod 3. When the sorghum stalks are pulled by the reel of the harvester's cutting platform 11, the sorghum is dragged to the position of the screw feeder in an inclined posture. The sorghum feeding process is divided into two parts: pressing down from a standing posture to an inclined state and tilting and dragging. The upright position of the sorghum ears before being pulled by the reel, combined with the limiting action of the stalk inclined pressure bar 3 during feeding, allows the sorghum ears to be fed more smoothly into the screw feeder. This prevents the sorghum ears from being dragged while standing and causing rapid swaying, thus preventing the sorghum from hitting the metal structure of the harvester's header 11. This reduces the impact on the sorghum ears during feeding and reduces grain loss. When the equipment is being loaded onto a vehicle or traveling on the road, the positioning pin 42 can be removed, the upper curved plate 2 can be flipped towards the driver's position, and then the upper curved plate 2 can be tightened by passing a chain through the limiting ring 23 and the fixing ring 5, reducing the overall length of the vehicle.
