Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, and particularly relates to an elastic diversion device. Background Art

[0002] After field operations, there are a large number of straws left, which will bring great difficulties to the next stubble of transplanting and sowing. To quickly process the straws and avoid environmental pollution caused by straw burning, the prior art discloses a straw pick-up baler. As Figure 1 shown, an existing diversion extension plate B is fixed inside the straw pick-up baler. The existing diversion extension plate B is not retractable. If it encounters a higher terrain during operation, it will collide, causing damage to the diversion extension plate and affecting the picking effect and operation efficiency.

[0003] Therefore, it is necessary to provide a new type of diversion device to solve the above technical problems. Content of the Utility Model

[0004] In view of the above problems, the utility model provides the following technical solutions:

[0005] An elastic diversion device, comprising a diversion extension plate, a support and a spring. The diversion extension plate includes an installation part and a diversion extension part. The installation part is in a bent shape. One end of the installation part is fixed on the machine housing. The swing end of the diversion extension part is connected to the support. The support is fixed on the machine housing. The spring is arranged between the support and the swing end of the diversion extension part.

[0006] Further, a reinforcing plate is fixed on the side of the diversion extension part that does not contact the material.

[0007] Further, one end of the installation part is installed on the machine housing through a fixing pin.

[0008] Further, the support is fixed on the machine housing through fasteners.

[0009] Further, the installation part and the diversion extension part are of an integral structure. The swing end of the diversion extension part is connected to the support through bolts and nuts.

[0010] Further, a first through hole is opened on the support. A second through hole is opened at the relative position of the swing end of the diversion extension part and the first through hole. The bolt sequentially passes through the first through hole and the second through hole and is fixed by the nut.

[0011] Further, a first gasket is arranged between the nut of the bolt and the support. A second gasket is arranged between the diversion extension part and the nut.

[0012] Furthermore, the diameters of the first through hole and the second through hole, the inner diameter of the central hole of the first gasket, the inner diameter of the central hole of the second gasket, and the diameter of the nut are adapted to each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By providing an elastic diversion device, when the machine encounters a higher terrain or an obstacle, the diversion extension plate will move upward to compress the spring. After the terrain becomes flat or the machine moves away from the obstacle, the spring's elastic force will push the diversion extension plate downward to return to its original state. In this way, the dynamic swing of the diversion extension plate and the telescoping of the spring are achieved, avoiding deformation and damage due to collision, effectively protecting the structure of the diversion extension plate, improving the picking efficiency, and extending the service life of the machine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to better understand the structure and function of the present utility model, the following further describes an elastic diversion device of the present utility model with reference to the drawings:

[0023] As shown Figure 2 in the figure, it is a schematic diagram of the overall structure of the present utility model, and the elastic diversion device is arranged on the machine housing A.

[0024] As shown Figure 3 and Figure 5 in the figure, the elastic diversion device includes a diversion extension plate 1, a support 2 and a spring 3.

[0025] The diversion extension plate 1 includes an installation part 110 and a diversion extension part 120. The installation part 110 is in a bent shape, and one end of it is rotatably installed on the machine housing A through a fixing pin 5, so that the diversion extension plate 1 can rotate freely when encountering an obstacle. The installation part 110 and the diversion extension part 120 are of an integral structure, and the swing end of the diversion extension part 120 is connected to the support 2 through a bolt 6 and a nut 7.

[0026] The support 2 is fixed on the machine housing A through a fastener 4.

[0027] The spring 3 is sleeved on the bolt 6 and is specifically installed between the support 2 and the swing end of the diversion extension part 120.

[0028] As a preferred embodiment, a reinforcing plate 130 is fixed on the non-material-contact side of the diversion extension part 120 to enhance the structural strength of the diversion extension part 120.

[0029] The specific connection manner between the swing end of the diversion extension part 120 and the support 2 is as follows: a first through hole 8 is opened on the support 2, and a second through hole 9 is opened at the relative position of the swing end of the diversion extension part 120 and the first through hole 8. The bolt 6 passes through the first through hole 8 and the second through hole 9 in sequence, and the nut 7 is screwed into the part of the bolt 6 that exposes the second through hole 9 to fix the bolt 6 on the diversion extension part 120 and the support 2.

[0030] The position where the nut 7 stays after being screwed into the bolt 6 can be adjusted up and down according to actual needs. To prevent the nut 7 from loosening during the operation of the machine and affecting the normal operation of the machine, the number of nuts 7 is preferably 2.

[0031] To better fix the bolt 6 and the nut 7 and improve the stability among the diversion extension plate 1, the support 2 and the bolt 6, as shown Figure 4 and Figure 5 in the figure, a first gasket 10 is provided between the support 2 and the nut of the bolt 6, and a second gasket 11 is provided between the diversion extension part 120 and the nut 7. The diameter of the first through hole 8 needs to be adapted to the diameter of the second through hole 9, the inner diameter of the central hole of the first gasket 10, the inner diameter of the central hole of the second gasket 11, and the diameter of the nut 7.

[0032] The usage process of the present utility model is as follows. When the machine is running and no obstacle is encountered, the spring 3 is in a free extension state. When an obstacle is encountered, under the blocking action of the obstacle, the axial rotation force of the installation part 110 pushes the diversion and extension part 120 upward to compress the spring 3. After moving away from the obstacle, under the elastic force of the spring 3, the diversion and extension part 120 moves downward and pushes the installation part 110 to axially rotate back to its original position, and the spring 3 returns to its normal state.
