Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a straw crop harvesting platform. Background Art

[0002] The function of the harvesting table is to harvest crops and transport them to the threshing device. The harvesting table is generally equipped with a straw divider to separate straw crops so that the crops can be classified to the cutting knife. After the crops are cut by the cutting knife, they fall into the hopper or conveying system. However, during the cutting and collecting process, some crops will fall to both sides and fall onto the cutting table's outrigger and the baffle of the outrigger. As the harvesting table moves forward, the outrigger vibrates and falls, resulting in crop waste.

[0003] Therefore, a straw crop harvesting platform capable of collecting crops dumped at the front outrigger is needed. Utility Model Content

[0004] In view of the problem in the prior art that part of the crops fall to the sides when the harvesting platform is harvesting, causing waste, the utility model provides a straw crop harvesting platform, which collects the straw crops that fall on the front outrigger by arranging a collection box to form a groove structure, thereby reducing waste.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a straw crop harvesting platform, the key is: including

[0006] A forward extension frame includes a crossbeam and a plurality of forward extension plates arranged in an array at the front end of the crossbeam;

[0007] A collecting box is fixedly connected above the front extension plate, and one end of the collecting box close to the crossbeam is open;

[0008] The blade guard assembly is installed on the crossbeams on both sides of the forward extension plate.

[0009] Straw crops such as rice and wheat pass through the straw divider and enter the groove between adjacent front extension plates, and are cut by the cutting knife clamped by the blade guard assembly. The severed ears of grain carry a certain length of straw, and this part of the crop is dumped into the collecting box under the push of the reel wheel or reel chain and the front extension frame; since the harvester continues to move forward and the field is not flat, the front extension frame vibrates with the forward movement of the harvester. The collecting box of this scheme is a concave structure. Compared with ordinary baffles, the dumped ears of grain are more likely to fall into the collecting box and are not easy to fall out after entering the collecting box; after completing a straight line of harvesting, the front extension frame is lifted to allow the ears of grain in the collecting box to fall from the opening of the collecting box into the conveyor belt or hopper.

[0010] Preferably, the collecting box comprises a bottom plate, side plates arranged on both sides of the bottom plate and a front sealing plate arranged at an end of the bottom plate away from the cross beam, and the bottom plate, side plates and front sealing plate are sealed and connected.

[0011] The collecting box is approximately in the shape of a dustpan, and as the front extension frame is lifted and tilted, the end of the bottom plate close to the front sealing plate also tilts accordingly. The rear end of the collecting box is unobstructed, and the ears of grain in the collecting box can more easily slide along the bottom plate of the collecting box to the hopper or conveyor belt.

[0012] Preferably, the side plate gradually decreases in height from one end connected to the front sealing plate to the other end, and the bottom plate is trapezoidal, with the end close to the front sealing plate being wider.

[0013] Since the front extension plate of the harvesting platform is a downward inclined structure when in use, the height of the lower front sealing plate is set higher, and the end of the side plate close to the front sealing plate is higher. Such a structure can make the internal space of the collecting box larger and the depth increased to accommodate more ears of grain and prevent the ears of grain from falling out easily.

[0014] Preferably, the side plates and the bottom plate are both hollow structures, and the collecting box further comprises a sealing plate for sealing the hollow structures of the side plates and the bottom plate.

[0015] The hollow structure of the side panels and the bottom panel can reduce weight, and the sealing panels can prevent debris or ears of grain from entering the hollow structure of the side panels and the bottom panel.

[0016] Preferably, the cross-section of the side panel is a triangular or trapezoidal structure.

[0017] The triangular or trapezoidal structure can make the side panel structure more temperature-resistant and less likely to deform.

[0018] Preferably, the blade guard assembly includes a blade guard seat and a blade guard, the blade guard seat is fixedly connected to the cross beam, and the blade guard is arranged below the forward extension plate.

[0019] Preferably, the outrigger further comprises guide plates arranged at both ends of the cross beam, and a conical opening is provided on the inward side of the guide plate and is rounded.

[0020] The deflector and tapered opening pull the crop together and into the recess where the blade guard assembly is located.

[0021] Preferably, the crossbeam is also fixedly connected to the rotating roller.

[0022] The rotation of the rotating roller drives the front extension frame to rotate and lift, so that the ears of grain in the collecting box fall into the hopper or the conveyor belt.

[0023] The beneficial effects of the utility model: this scheme adopts a collection box installed on the forward extending plate to replace the baffle to collect the ears of grain that tilt to both sides. The collecting box is a recessed structure with a certain depth. Compared with the flat baffle, the ears of grain are easy to slide down after falling on the baffle, especially when the harvester continues to move forward and drives the harvesting table to vibrate, the baffle with a flat structure makes it easy for the ears of grain to slide down from both sides of the baffle. The collecting box of this scheme can directly fall into the space with depth when the ears of grain fall, and even if the harvesting table drives the collecting box to vibrate, the ears of grain are not easy to fall out of the collecting box.
