Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a function quick switching device for a rear crusher of a harvester. Background Art

[0002] Agricultural mechanization is becoming more and more popular. Combine harvesters are used to harvest crops such as wheat and rice. There are two ways to deal with the straw after threshing. One is to configure a straw crushing device on the combine harvester. The straw crushing device is arranged at the grass outlet of the threshing chamber. The threshed straw in the threshing chamber of the combine harvester is transported to the straw crushing device, crushed by the straw crushing device, and then thrown into the farmland to realize the return of straw to the field. The other is to directly discharge the straw output from the threshing chamber of the combine harvester, spread it on the ground, and then collect the straw by other machines later, so that the complete straw is easy to recycle. Different ways of dealing with the straw after threshing require the harvester to be able to adapt to different harvesting requirements. Existing harvesters are usually equipped with straw crushing devices, which are fixed to the grass outlet on the rear side of the threshing chamber by bolts. In order to effectively adjust the crusher, it is generally necessary to install a flip mechanism on the crusher.

[0003] However, the flip mechanism in the prior art has a complex structure and many installation parts. It is either easy to install or disassemble, but the crusher needs to be disassembled every time the straw crushing or direct return to the field function is changed; the operation steps may be cumbersome, and the harvesting efficiency may need to be further improved. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and to propose a function fast switching device for a harvester rear crusher.

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

[0006] A function quick switching device for a harvester rear-mounted pulverizer comprises a harvester body, a pulverizer body is connected to the harvester body, and further comprises:

[0007] A symmetrically arranged connecting plate is fixedly connected to the pulverizer body;

[0008] The symmetrically arranged mounting plates are fixedly connected to the connecting plate;

[0009] A rotating rod, rotatably connected to the mounting plate;

[0010] A baffle, fixedly connected to the rotating rod;

[0011] The transition plate is fixedly connected to the baffle plate, and the transition plate box is fixedly connected to the rotating rod.

[0012] Preferably, a limit plate is fixedly connected to the harvester body, and the limit plate and the baffle plate abut against each other.

[0013] Preferably, a handle is fixedly connected to the rotating rod.

[0014] Compared with the prior art, the utility model provides a function quick switching device for a harvester rear crusher, which has the following beneficial effects:

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model adds a function switching device to the crusher body. The baffle can be quickly and synchronously driven to rotate by manually pulling the handle. The baffle can be opened and closed by rotating the baffle to quickly realize the switching between the straw crushing function and the straw not crushed and directly returning to the field function, thereby effectively improving the harvesting efficiency.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] Reference Figure 1-Figure 5 A function quick switching device for a harvester rear-mounted crusher includes a harvester body 7, a crusher body 6 is connected to the harvester body 7, and further includes:

[0025] A symmetrically arranged connecting plate 1 is fixedly connected to the pulverizer body 6;

[0026] A sealing plate is fixedly connected between the two symmetrically arranged groups of connecting plates 1;

[0027] A symmetrically arranged mounting plate 3 is fixedly connected to the connecting plate 1;

[0028] The rotating rod 401 is rotatably connected to the mounting plate 3;

[0029] Baffle 2, fixedly connected to the rotating rod 401;

[0030] The transition plate 5 is fixedly connected to the baffle plate 2 , and the transition plate 5 and the rotating rod 401 are fixedly connected.

[0031] A limit plate 701 is fixedly connected to the harvester body 7 , and the limit plate 701 and the baffle plate 2 abut against each other.

[0032] Reference Figure 1 The transition plate 5 can prevent the straw from being retained and accumulated, making the straw slide down more smoothly and not easy to be blocked.

[0033] The handle 4 is fixedly connected to the rotating rod 401 .

[0034] Reference Figure 1-Figure 5 During use, when the straw crushing function is needed, the handle 4 is manually pulled, and the handle 4 will drive the rotating rod 401 to rotate, and the rotation of the rotating rod 401 will drive the baffle 2 to rotate synchronously. At this time, the baffle 2 rotates clockwise. When the baffle 2 rotates to a certain angle, the baffle 2 and the limit plate 701 on the harvester body 7 are against each other, and the straw will slide down into the crusher body 6 for crushing;

[0035] When there is no need to crush the straw and the straw can be returned to the field directly, the staff can manually pull the handle 4 in the opposite direction, and the handle 4 will drive the rotating rod 401 to rotate in the opposite direction, and the reverse rotation of the rotating rod 401 will drive the baffle 2 to rotate in the opposite direction, and the baffle 2 will rotate counterclockwise to reset. When the baffle 2 rotates to a certain angle, the baffle 2 will be against the sealing plate, and the baffle 2 will cover as much of the channel above the crusher body 6 as possible, and when the baffle 2 rotates to reset, a grass discharge port is vacated between the harvester body 7 and the mounting plate 3, and the straw can be directly discharged through the grass discharge port and returned to the field.

[0036] The utility model adds a function switching device to the crusher body 6, and the baffle 2 can be quickly and synchronously driven to rotate by manually pulling the handle 4. The baffle 2 can be turned on and off by rotating it to quickly switch between the straw crushing function and the straw non-crushing and direct return to the field function, thereby effectively improving the harvesting efficiency.

[0037] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
