Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a material discharging device for agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery. Among them, the machine that threshes the dried corn ears is called a corn thresher.

[0003] When the current corn thresher is in operation, there will be grains remaining on the cob, which needs to be operated again. However, the direction in which the cob is discharged from the discharge port cannot be adjusted, so the cob and the grains are often piled together, which makes it very troublesome to find the cob with grains remaining. Utility Model Content

[0004] The utility model is intended to provide a discharging device for agricultural machinery, so as to solve the problem in the prior art that the direction in which the cobs are discharged from the discharging port cannot be adjusted during the operation of the corn thresher, resulting in the accumulation of cobs and grains.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0007] The principle of this technical solution:

[0008] The device is fixed to the cob discharge port of the corn thresher through the fixing hole, and after the discharge pipe is adjusted to a suitable direction by the control switch, the corn thresher is turned on, and the cobs will be discharged from the discharge pipe and will not be accumulated with the grains.

[0009] Preferably, two fixing rods are fixedly connected to the bottom of the fixing plate, a clamping plate is fixedly connected to the bottom of the fixing rod, a lower clamping arm of the clamping plate is provided with a bolt, and a pressing plate is fixedly connected to the top of the bolt.

[0010] Preferably, an anti-slip pad is fixedly connected to the top of the extrusion plate.

[0011] Preferably, the discharge pipe is provided with a plurality of discharge holes.

[0012] Beneficial effects of this technical solution:

[0013] (1) The device can adjust the direction of the discharge pipe to prevent the cobs and grains from piling up together.

[0014] (2) The clamping plate can make the device more firmly fixed on the corn thresher.

[0015] (3) The grains mixed between the cobs can also be discharged through the discharge holes, and fewer grains are mixed with the cobs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0023] See also Figures 1 to 5A discharging device for agricultural machinery comprises a quadrangular prism 1 with upper and lower openings 7, the bottom cross section of the quadrangular prism 1 is smaller than the top cross section, a funnel 2 is fixedly connected to the bottom of the quadrangular prism 1, a hollow transmission gear 3 is rotatably sleeved on the outer wall of the mouth of the funnel 2, a groove 4 is provided in the transmission gear 3, a limiting ring 5 corresponding to the groove 4 is fixedly connected to the bottom of the funnel 2, and the outer diameter of the limiting ring 5 is larger than the outer diameter of the mouth of the funnel 2, a discharging pipe 6 inclined downward is fixedly connected to the bottom of the transmission gear 3, and a plurality of discharging holes 16 are provided on the discharging pipe 6, the quadrangular prism 1 is fixedly connected to the bottom of the transmission gear 3, and a plurality of discharging holes 16 are provided on the discharging pipe 6, and the quadrangular prism 1 is fixedly connected to the bottom of the transmission gear 3. An upward opening 7 is provided on the rear wall of the prism 1, and a plurality of fixing holes 8 are provided on both sides of the opening 7, a fixing plate 9 is fixedly connected to the opening 7, a motor 10, two fixing rods 12 and a control switch electrically connected to the motor 10 are fixedly connected to the bottom of the fixing plate 9, an output shaft of the motor 10 is fixedly connected to an output gear 11 meshing with the transmission gear 3, a clamping plate 13 is fixedly connected to the bottom of the fixing rod 12, a bolt 14 is provided on the lower clamping arm of the clamping plate 13, an extrusion plate 15 is fixedly connected to the top of the bolt 14, and an anti-slip pad is fixedly connected to the top of the extrusion plate 15.
