Description

Technical Field

[0001] The utility model belongs to a harvester, and in particular relates to a herbaceous mulberry harvester. Background Art

[0002] When harvesting mulberry strips, the height of the header needs to be changed due to terrain and changes in the harvesting height. Conventional mulberry strip harvesters cannot automatically adjust the harvesting height and can only be adjusted by manually lifting the header or changing the bolt fixing position. This method is extremely inconvenient and manual lifting is dangerous and consumes a lot of workers' physical strength. On the other hand, the harvesting height is difficult to maintain. At the same time, after adjusting the header height, existing mulberry strip harvesters also need to adjust the conveying device for conveying mulberry strips to adapt to the height of the header in order to ensure smooth connection between harvesting and conveying operations. This adjustment process requires professional operators to complete, the operation is complicated and the operation efficiency is low. Utility Model Content

[0024] like Figure 1 、 Figure 2 As shown, the herbaceous mulberry harvester described in the present invention includes a main machine assembly 1, on which a cutting platform lifting device 2, a cutting platform device 3, a lifting connecting device 4, a conveying device 5, a main machine connecting device 6 and a stacking device 7 are installed.

The header device 3 and the stacking device 7 in the present utility model belong to the existing technology in this field, and the specific structure will not be described in detail here.

[0026] like Figure 3As shown, the cutting platform lifting device 2 includes a lifting float 21, a lifting slide rail 24, a hydraulic cylinder 25 and a connecting part 26. The lifting float 21 is slidably connected to the lifting slide rail 24. A rectangular groove structure is provided on the inner side of the lifting slide rail 24. The lifting float 21 is movably inserted into the rectangular groove structure of the two lifting slide rails 24 through the sliders 42 on both sides to realize the limitation and guidance of the lifting float 21. The cylinder body and telescopic rod of the hydraulic cylinder 25 are respectively connected to the main machine assembly 1 and the lifting float 21. The hydraulic cylinder 25 realizes the up and down height adjustment of the cutting platform device 3 through the action of the telescopic rod. The lifting float 21 is connected to the cutting platform device 3 through the connecting part 26.

[0027] Furthermore, in order to limit the tilting tendency of the lifting float 21 to the sides and front and back directions during the lifting process of the hydraulic cylinder 25 and to reduce the friction force of the lifting float 21 during the lifting process, the lifting float 21 is provided with a side limiting pulley 22 and a front limiting pulley 23, and the side limiting pulley 22 and the front limiting pulley 23 are in sliding contact with the front and side of the lifting slide rail 24 respectively.

[0029] The lifting connection device 4 realizes a compound arc motion by combining the rotational motion of the bearing seat 43 and the slider 42 and the linear motion of the slider 42 and the guide rail 41, thereby realizing the synchronous lifting and lowering of the front end of the conveying device 5 and the cutting table device 3 when the cutting table device 3 is lifted or lowered to adapt to different harvesting heights.

[0030] like Figure 5 As shown, the main engine assembly 1 includes a frame 11 and an engine 12, a total output shaft 13, a cutting platform power input shaft 14, a right-angle gearbox 15 and a stacking power input shaft 16 installed on the frame 11.

[0031] During the power output process, the engine 12 first outputs power to the total output shaft 13, and then the total output shaft 13 transmits power to the cutting platform power input shaft 14 and the right-angle shaft gearbox 15 at the same time through belt transmission, and then the cutting platform power input shaft 14 outputs power to the cutting platform device 3. At the same time, the right-angle shaft gearbox 15 transmits power to the power input shaft of the stacking device 7 on the one hand, and transmits power to the stacking device 7 through the power input shaft. On the other hand, the belt arrangement can be converted from a vertical plane to a horizontal plane, and the rotation direction of the pulley is changed, and the power is transmitted to the conveying device 5 through the main machine connection device 6; during the power transmission process, the transmission ratio between the various components is changed by the pulley, so that the conveying speed of the conveying device 5 is greater than the conveying speed of the cutting platform device 3, so that the mulberry strip conveying can be carried out smoothly and avoid blockage; at the same time, the clutch of the entire transmission system is arranged on the total output shaft 13, so that a clutch can be realized to control the work other than the main machine walking.

[0032] like Figure 6 As shown, the main machine connecting device 6 includes a connecting base plate 61, a conveying power input shaft 62, a vertical support 63, a pin 64, an upper fixed plate 65 and a relay transmission assembly 66. The connecting base plate 61 is fixedly connected to the frame 11 of the main machine assembly 1, the vertical support 63 is fixedly connected to the connecting base plate 61, the upper fixed plate 65 is fixedly connected to the rear end of the conveying device 5, and is rotatably connected to the vertical support 63 through the pin 64. The conveying power input shaft 62 and the relay transmission assembly 66 are installed on the connecting base plate 61. The conveying power input shaft 62 is connected to the relay transmission assembly 66 through an intermediate sprocket and a chain. The relay transmission assembly 66 is connected to the output shaft of the right-angle gearbox 15 through a pulley assembly.

[0033] The main engine connection device 6 is used to transmit power to the conveying device 5. At the same time, the cutting platform device 3 can serve as a rotation fulcrum at the rear of the conveying device 5 when it is raised or lowered, so that the rear end outlet of the conveying device 5 is adapted to the stacking device 7.

[0034] like Figure 7 、 Figure 8The gear chain 52 is connected to the plurality of conveying sprockets 53 in a horizontal manner and is evenly connected to the plurality of conveying sprockets 53. The gear chain 52 is connected to the plurality of conveying sprockets 53 in a horizontal manner. The gear chain 52 is connected to the plurality of conveying sprockets 53 in a transmission manner. The gear chain 52 comprises a chain and a plurality of gears evenly fixed on the chain. The upper baffle 54 and the lower baffle 55 are respectively fixed to the upper and lower parts of the support frame 51. The guide plate 56 is fixed to the middle part of the support frame 51 and is away from the outer sides of the upper baffle 54 and the lower baffle 55. The side of the guide plate 56 close to the upper baffle 54 and the lower baffle 55 is connected to the grain pressing tube 58 by a plurality of springs 57. The bottom supporting plate 59 is fixedly connected to the bottom of the support frame 51 near the outer side of the lower baffle 55. The conveying sprocket 53 at the rear end is connected to the conveying power input shaft 62 in a transmission manner to realize the input of power.

[0035] Furthermore, in order to facilitate the accurate delivery of the mulberry branches conveyed by the conveying device 5 to the stacking device 7, a horizontally arranged reel 510 is provided at the rear end of the support frame 51, and the reel 510 is provided with a plurality of evenly distributed reel teeth.

[0036] The working process of the present invention is as follows: when in use, after starting the main engine assembly 1, the machine is moved to a suitable position, and the header device 3 is adjusted to a suitable harvesting height by adjusting the hydraulic cylinder 25. Then, the header device 3, the conveying device 5 and the stacking device 7 are started by the clutch control of the total output shaft 13. When working, the header device 3 first vertically transmits the harvested mulberry strips to the entrance of the conveying device 5, and the mulberry strips vertically enter the gap between the pressing pipe 58 and the upper baffle 54 and the lower baffle 55. The guide plate 56 and the pressing pipe 58 are bent outward to expand the entrance to facilitate the entry of the mulberry strips. When the mulberry strips enter the gap between the pressing pipe 58 and the upper baffle 54 and the lower baffle 55, the pressing pipe 58 presses the mulberry strips under the action of the elastic force of the spring 57. On the outer wall of the upper baffle 54 and the lower baffle 55, the bottom support plate 59 supports the bottom of the mulberry strips to keep them in a vertical state. At this time, the conveying sprocket 53 drives the tooth chain assembly 52 to move. During the movement, when the teeth of the tooth chain assembly 52 move to the mulberry strip position, the mulberry strips are moved along the direction of the guide plate 56 and the straw pressing tube 58. After the mulberry strips are pushed to the rear end of the conveying device 5, they enter the straw teeth of the straw wheel 510. Under the guidance of the straw wheel 510, the mulberry strips are accurately transferred to the stacking device 7. The mulberry strips will be stacked in the stacking device 7. The sensor in the stacking device 7 senses the number of stacked mulberry strips. When the stacked amount of mulberry strips reaches the set standard, the fork assembly of the stacking device 7 will be triggered to remove the stacked mulberry strips.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
