Description
Technical Field
[0001] The invention relates to the technical field of wheat seed harvesting, and in particular to a harvesting machine used for wheat seed harvesting. Background Art
[0002] A wheat seed harvester refers to a piece of mechanical equipment specifically used for harvesting wheat seeds. This type of machine is usually used in demonstration areas for wheat seed breeding to ensure efficient harvesting of wheat seeds. Wheat seeds are very important seed resources in agricultural planting, and their quality and yield directly affect subsequent agricultural production benefits.
[0003] With the continuous development of agricultural science and technology, most of the existing wheat seed harvesting machinery adopts combine harvesters. At present, the main components of combine harvesters include harvesting platform, threshing device, separation and cleaning device, engine, transmission system, electrical system, hydraulic system, intermediate conveying device, chassis bracket, crawler walking device and granary, etc. These components work together to enable the combine harvester to efficiently complete the harvesting, threshing, separation and cleaning processes of cereal crops. However, although the existing combine harvesters have high harvesting efficiency, after the harvesting is completed and the wheat seeds are stored in the granary, some bad seeds or broken seeds during the harvesting process will still be stored in the granary due to the influence of the agricultural machinery itself or the seeds themselves. Although these seeds do not affect normal processing and consumption, once they are put into the planting area, the overall germination rate of the wheat seed will be greatly reduced, and the quality of the wheat seed will be reduced. For this reason, we propose a harvesting machinery for harvesting wheat seed. Summary of the invention

[0014] In order to prevent the wheat seeds from splashing randomly during unloading, one side of the longitudinal feeding cylinder is also connected to a flexible unloading pipe for discharging the wheat seeds.
[0015] The working principle and beneficial effects of the present invention are: 1. After the present invention is installed on a combine harvester, a feed pipe is connected to a threshing mechanism on the combine harvester, and the wheat seeds separated from the wheat plants are guided to a storage granary through the threshing mechanism. After the wheat seeds enter the storage granary, they are gathered in a conical mixing hopper under the guidance of a guide hopper, and are guided to a circular screening plate through a discharge cavity. At this time, a mixing motor is started, and the output end of the mixing motor drives the conical mixing barrel to rotate, and the rotation of the conical mixing head drives the stirring rod to rotate. Through the rotation of the conical mixing head and the stirring rod, The wheat seeds falling through the feeding cavity are stirred. As the stirring rod rotates, the wheat seeds collide with each other. During the collision, the powder ash or wheat awns adsorbed on the wheat seeds will be separated from the wheat seeds. After the wheat seeds fall on the circular screening plate, the rotation of the conical mixing head drives the material shifting plate to rotate at the same time. The rotation of the material shifting plate shifts the wheat seeds scattered on the circular screening plate to the bottom of the storage granary. In the process of shifting the wheat seeds, the mixed grains or dust in the wheat seeds will be separated into the impurity discharge pipe through the convex impurity discharge port. 2. The present invention starts the exhaust fan while stirring the wheat seeds to separate the impurities. Under the suction of the exhaust fan, it is more helpful for lighter foreign matters such as dust or wheat awns to pass through the convex impurity discharge port. Under the suction of the exhaust fan, the lighter dust or wheat awns will be discharged into the air from the exhaust box along the impurity discharge pipe and the impurity suction pipe, while the broken wheat seeds will accumulate at the bottom of the impurity discharge pipe due to the action of gravity. By opening the impurity discharge valve, the broken wheat seeds can be collected for processing and consumption; 3. In the present invention, after filtering the wheat seeds, the high-quality wheat seeds are accumulated at the bottom of the storage granary. When the wheat seeds are unloaded, the power motor is started, and the output end of the power motor drives the power rotating rod to rotate. The rotation of the power rotating rod drives the bevel gear 1 and the feed gear 1 to rotate simultaneously. The rotation of the bevel gear 1 drives the bevel gear 2 to rotate. The rotation of the bevel gear 2 drives the longitudinal feed rod to rotate. The rotation of the longitudinal feed rod drives the longitudinal spiral feed blade to rotate. The rotation of the feed gear 1 drives the feed gear 2 to rotate. The rotation of the feed gear 2 drives the transverse feed rod to rotate. The rotation of the transverse feed rod drives the transverse spiral feed blade to rotate, so that the transverse spiral feed blade rotates. The feeding blades and the longitudinal spiral feeding blades rotate synchronously. By setting the rotation direction of the transverse spiral feeding blades and the longitudinal spiral feeding blades, the transverse spiral feeding blades drive the wheat seeds in the storage granary to move toward the longitudinal feeding cylinder, and the rotation of the longitudinal spiral feeding blades will drive the wheat seeds to move toward the direction of the flexible unloading pipe. By adjusting the gear ratio of bevel gear 1 and bevel gear 2 and feeding gear 1 and feeding gear 2, the rotation speed of the transverse spiral feeding blades driven by the power motor is made lower than the rotation speed of the longitudinal spiral feeding blades. In this conveying process, the secondary damage caused by extrusion between the wheat seeds can be minimized, and the wheat seeds can be better conveyed and unloaded quickly.

A plurality of stirring rods 6 are provided, and the stirring rods 6 are arranged on the conical mixing head 5.
[0022] Among them, the screening component includes a circular screening plate 7, a drainage pipe 8, a drainage gate valve 9 and a material shifting plate 10. The circular screening plate 7 is arranged in the material storage silo 1, and the circular screening plate 7 is located below the conical mixing head 5. A semicircular groove is provided on the circular screening plate 7.

[0023] Specifically, after the wheat seeds enter the storage granary 1, they will gather in the conical mixing hopper under the guidance of the guide hopper 3, and will be guided to the circular screening plate 7 through the discharge cavity. At this time, the mixing motor 4 is started, and the output end of the mixing motor 4 drives the conical mixing barrel to rotate.

The suction of the exhaust fan is more conducive to the passage of lighter foreign matter such as dust or wheat awns through the convex impurity discharge port. Under the suction of the exhaust fan, the lighter dust or wheat awns will be discharged into the air from the exhaust box 11 along the impurity discharge pipe 8 and the impurity suction pipe 13, while the broken wheat seeds will accumulate at the bottom of the impurity discharge pipe 8 due to the action of gravity. By opening the impurity discharge valve, the broken wheat seeds can be collected for processing and consumption.

[0027] Among them, the transverse feeding assembly includes a transverse feeding cylinder 15, a transverse feeding rod 16 and a transverse spiral feeding blade 17. The transverse feeding cylinder 15 is connected and arranged at the bottom of the storage granary 1. The transverse feeding rod 16 penetrates and is rotatably arranged in the transverse feeding cylinder 15. The transverse spiral feeding blade 17 is arranged on the transverse feeding rod 16, and the transverse spiral feeding blade 17 is in contact with the inner wall of the transverse feeding cylinder 15.
[0028] Among them, the longitudinal feeding assembly includes a longitudinal feeding cylinder 18, a longitudinal feeding rod 19 and a longitudinal spiral feeding blade 20. The longitudinal feeding cylinder 18 is arranged on one side of the storage granary 1. The longitudinal feeding cylinder 18 passes through the automatic discharge box 14.

[0030] Specifically, after filtering the wheat seeds, the high-quality wheat seeds are accumulated at the bottom of the storage granary 1. When the wheat seeds are unloaded, the power motor 22 is started, and the output end of the power motor 22 drives the power rotating rod 21 to rotate. The rotation of the power rotating rod 21 drives the bevel gear 1 23 and the feeding gear 1 25 to rotate at the same time. The rotation of the bevel gear 1 23 drives the bevel gear 2 24 to rotate. The rotation of the bevel gear 2 24 drives the longitudinal feeding rod 19 to rotate. The rotation of the longitudinal feeding rod 19 drives the longitudinal spiral feeding blade 20 to rotate. The rotation of the feeding gear 1 25 drives the feeding gear 2 26 to rotate. The rotation of the feeding gear 2 26 drives the transverse feeding rod 16 to rotate.

In this conveying process, the wheat seeds can minimize the secondary damage caused by extrusion between the wheat seeds, and the wheat seeds can be better conveyed and unloaded quickly.
[0031] It should be noted that in order to prevent the wheat seeds from splashing during unloading, a flexible unloading pipe 27 is connected to one side of the longitudinal conveying cylinder 18. The flexible unloading pipe 27 blocks the wheat seeds during the discharge process, making it easier for the wheat seeds to fall onto the conveying equipment.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
