Description

Versatile grain combine with interchangeable threshing units

technical field

The utility model relates to a harvesting machine for grain crops, which belongs to a full-feed grain combine harvester, in particular to a multifunctional grain combine harvester with interchangeable threshing devices.

Background technique

At present, the basic component devices of full-feed grain combine harvesters at home and abroad are the same, and they are all composed of headers, conveying bridges, threshing devices, separation devices, cleaning structures, grain lifting, miscellaneous lifting, granary , chassis system, cab control system, power system, hydraulic electrical system and other components. However, due to the different threshing and separation devices, two types of structural models have been formed, one is the traditional key-type drafter type, and the other is the axial-flow drum type. Although both can perform grain harvesting operations, the emphasis is different. The traditional key-type straw walker model is mainly suitable for harvesting wheat, and the discharged straw is relatively complete, which is beneficial to the straw baling operation. The axial flow drum type is suitable for harvesting corn and other crops. Due to the maintenance of a sufficient material layer, the crops are repeatedly hit softly during the process of passing through the harvester. The material passes through the harvester for a long time, and the material is fully and thoroughly Threshing and separation can reduce grain loss and obtain good grain quality; but the discharged straw is relatively broken, which is not suitable for straw baling.

Description of drawings

The utility model will be further described below in conjunction with the accompanying drawings. Fig. 1 is a schematic structural view of Embodiment 1 of the present utility model, and Fig. 2 is a schematic structural view of Embodiment 2 of the present utility model.

Detailed ways

A multifunctional grain combine harvester with interchangeable threshing devices, as shown in Figure 1 and Figure 2, includes a power system 9 installed on a chassis frame 4 with wheels, a conveying bridge 2, grains and miscellaneous Lifting device 8, winnowing vibrating and cleaning screen mechanism 10 and granary 7, wheat header 1 or corn header 12 are installed at the front end of conveying bridge 2, and cutters are installed successively at the discharge end of conveying bridge 2. The flow threshing drum device 5, the draft wheel device 6 and the key type draft separator separation device 11 or the double longitudinal threshing separation drum device 13, the intermediate shaft device 14 and the grass discharge wheel are installed in sequence at the discharge end of the conveying bridge 2 device 15.

As shown in the figure, when wheat is harvested, a wheat header 1 is installed at the front end of the conveying bridge 2, and a cut-flow threshing drum device 5, a draft device 6 and a key are installed sequentially at the discharge end of the conveying bridge 2. Type document chaser separation device 11.

Workflow:

When harvesting wheat, the reel on the header 1 pushes the crops into the cutting knife, and the crop stalks are cut off quickly under the reciprocating cutting action of the cutting knife and sent to the auger, and then fed by the auger to the inclined conveying bridge 2 . Then the crops are sent to the cross-flow threshing drum device 5 by the cross-bridge rake bar, kneading and combing in the cross-flow threshing drum device 5 to complete threshing. The stalks and protruding objects are fully thrown and vibrated by the key-type draft remover separation device 11, the stalks are discharged from the body, and the grains fall into the cleaning sieve. Under the action of the fan, the chaff and impurities in the falling grain extracts are blown out. Under the action of the sieve, the de-cleaned grains fall into the grain elevator in the grain and miscellaneous lifting device 8, thereby being transported to the granary 7; The waste elevator is transported back to the cutting flow threshing drum device 5 for secondary re-extraction. Finally, the driver controls the unloading barrel to complete the unloading.

As shown in Figure 2, when corn is harvested, a corn header 12 is installed at the front end of the conveying bridge 2, and a double longitudinal threshing and separating drum device 13 and an intermediate shaft device 14 are sequentially installed at the discharge end of the conveying bridge 2 And the grass wheel device 15.

Workflow:

Corn crops are dialed into the crop passage through the reel chain on the corn header 12, and the lower knife-type stalk puller pulls the stalks to the ground. Conveying across the bridge 2, the material is transported from the conveying bridge 2 to the double longitudinal threshing separation drum device 13, the grain bar and the concave plate in the front section of the double longitudinal threshing separation drum rotate and knead and comb the material for threshing. The concave plate rotates and separates the materials. The fixed guide blades installed on the inner wall of the upper cover of the drum chamber help the material move backwards and spirally, and provide maximum separation for the grains in the material layer under the action of the rotating centrifugal force. During this process, the separated grains fall on the winnowing vibration cleaning screen mechanism 10 located at the lower part of the threshing and separating concave plate, and the materials that have passed through are discharged from the rear of the concave plate, and are discharged by the rear grass discharge wheel device 15. It is excreted from the body. Under the action of the fan, the chaff and impurities in the falling grain extracts are blown out. Under the action of the sieve, the de-cleaned grains fall into the grain elevator in the grain and miscellaneous lifting device 8, thereby being transported to the granary 7; The waste elevator is conveyed back to the threshing drum for secondary re-extraction. Finally, the driver controls the unloading barrel to complete the unloading.
