Abstract
The utility model discloses an improved threshing cylinder device for a combine harvester, and relates to the technical field of agricultural machinery. The improved threshing cylinder device mainly comprises a cylinder, a concave plate, bent T-shaped teeth and T-shaped tooth grooves. The improved threshing cylinder device is characterized in that the bent T-shaped teeth are fixedly connected with rasp bars arranged on the cylinder; the T-shaped tooth grooves are formed on the concave plate, and correspond to the bent T-shaped teeth fixed to the rasp bars; and when the cylinder rotates, the bent T-shaped teeth pass through the T-shaped tooth grooves. Compared with the prior art, the utility model has the advantages that the structural design is reasonable and practical, and because the rasp bars are provided with the bent T-shaped teeth, the concave plate is provided with the T-shaped tooth grooves and the bent T-shaped teeth pass through the T-shaped tooth grooves when the cylinder rotates, stalks on the concave plate are timely thrown, the blockage of concave plate holes is reduced, the grain entraining rate in the stalks can be effectively reduced, the threshing cylinder can be prevented from being blocked and stopping, and the harvest efficiency and the harvest quality of the combine harvester are improved.
Description
Technical field
The utility model relates to agricultural machinery technological field, particularly a kind of improved combine threshing cylinder device.
Background technology
At present, the threshing cylinder of combine is especially cut the streaming threshing cylinder when work; Often there is the stalk of high humidity to hang in the notch board hole, makes the notch board hole plug, cause the stalk grain clamping rate high; Cause grain loss, cause the gap of cylinder and notch board to dwindle simultaneously, occur easily stopping up and shut down; Influence the harvesting efficiency of combine, percentage of damage strengthens when the harvesting legume crop, has a strong impact on the harvesting quality of combine.
Summary of the invention
The utility model purpose is: the problem to prior art exists is improved, and design provides a kind of simple in structure, can effectively reduce the combine threshing cylinder device of notch board hole plug.
The utility model solves the technical scheme that its technical problem adopted: a kind of improved combine threshing cylinder device; Mainly comprise cylinder, notch board, bending gear teeth and fourth teeth groove; It is characterized in that: bending gear teeth is fixedly connected with rasp bar on being installed in cylinder; The fourth teeth groove is arranged on the notch board, and the position of fourth teeth groove is corresponding with the position of bending gear teeth on being fixed on rasp bar, and bending gear teeth passes through in the fourth teeth groove during rollers running.
Said cylinder and notch board are prior art, do not do too much description here.
Present technique is compared with prior art, has the reasonable in design practicality, owing to installing bending gear teeth on the rasp bar additional and on notch board, be provided with the fourth teeth groove; Bending gear teeth passes through in the fourth teeth groove during rollers running; In time the stalk on the notch board is dished out, reduced the obstruction in notch board hole, can effectively reduce the grain clamping rate in the stalk; Can prevent that threshing cylinder from stopping up shutdown, improved the harvesting efficiency and the harvesting quality of combine.
Description of drawings
Fig. 1 is the cylinder longitudinal profile sketch map of the utility model.
Fig. 2 is the notch board fore-and-aft plane sketch map of the utility model.
Fig. 3 is the cylinder and the notch board assembling sketch map of the utility model.
Among the figure: 1 cylinder, 2 notch boards, 3 rasp bars, 4 bending gear teeths, 5 fourth teeth groove.
Embodiment
Bending gear teeth 4 is fixedly connected with rasp bar 3 on being installed in cylinder 1, and fourth teeth groove 5 is arranged on the notch board 2, be fixed on rasp bar 3 on the position of bending gear teeth 4 corresponding, bending gear teeth 4 passes through in fourth teeth groove 5 during cylinder 1 running.Owing to installing bending gear teeth 4 on the rasp bar 3 additional and fourth teeth groove 5 be set on notch board 2; Bending gear teeth 4 passes through in fourth teeth groove 5 during cylinder 1 running; In time the stalk on the notch board 2 is dished out, reduced the obstruction in notch board hole, can effectively reduce the grain clamping rate in the stalk; Can prevent that threshing cylinder from stopping up shutdown, improves the harvesting efficiency and the harvesting quality of combine.
