Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed melon harvesting machine, and specifically relates to a seed melon combined harvester cutting seedling assembly. BACKGROUND

[0002] In the traditional seed melon harvesting machine, long-toothed rollers are usually used to bind the seed melon to the rollers, and after the rotation of the rollers, the melon vines and sundries fall into the sundry removal mechanism below. However, this traditional harvesting method has many problems. First, the broken melon vines and sundries are easy to entangle on the machine body, resulting in poor sundry removal effect, especially during long-time operation, the entanglement phenomenon is more serious, affecting the normal operation of the machine. Secondly, due to the accumulation of melon vines and sundries, the operation components are easy to be blocked, thereby affecting the harvesting effect of seed melon and reducing the operation efficiency. In addition, the traditional harvesting machine often cannot achieve efficient and uniform cutting when cutting melon vines, resulting in an unsmooth transmission and sundry removal process of melon vines, further aggravating the accumulation and entanglement of sundries. Therefore, there is an urgent need for a cutting seedling assembly that can effectively solve the problems of melon vine entanglement and sundry accumulation to improve the operation efficiency and reliability of the seed melon harvesting machine.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-9 A vine-cutting component for a seed melon combine harvester is mounted on the harvester's mounting frame 11 and combined with the harvester's long-toothed roller 12 and debris removal component 13.

[0034] It includes a cutting shaft 2 and a forward blade 31 and a backward blade 32 mounted on the cutting shaft 2. The cutting shaft 2 is rotatably mounted on the mounting frame 11 and arranged above the long toothed roller 12. The forward blade 31 and the backward blade 32 are arranged facing the front and rear sides of the mounting frame 11, respectively.

[0035] It also includes toothed plates 4 and cleaning scrapers 5, which are fixedly installed on the mounting frame 11 and respectively arranged on the front and rear sides of the cutting shaft 2. The cleaning scrapers 5 include multiple evenly distributed sets, and the ends of the cleaning scrapers 5 are provided with upwardly inclined bent sections 51. Forward blades 31 and backward blades 32 are arranged in the gaps of the cleaning scrapers 5 and in the toothed grooves of the toothed plates 4. The backward blades 32 cooperate with the toothed plates 4 to cut the melon vines.

[0036] A guide plate 6 is provided on the toothed plate 4. The guide plate 6 has a relief groove 61 that matches the toothed groove on the toothed plate 4. The front side of the guide plate 6 is connected to the impurity removal component 13.

[0037] The seed melon harvester is driven by an agricultural tractor or other vehicle to move and operate in the field. When the toothed roller 14 at the front of the harvester is running, the seeds of the melon can be stuck on the teeth and move together with the melon vines along with the toothed roller 14. Then, they are captured by the long toothed roller 12 at the rear. As the long toothed roller 12 moves backward, the seeds of the melon are captured by the collecting component 15 at the rear and crushed to extract the seeds, while the melon vines continue to move with the long toothed roller 12 to the cutting component above.

[0038] During the operation of the cutting shaft 2 in the cutting assembly, which drives the forward blade 31 and the backward blade 32, the forward blade 31 can drag the melon vines to move them towards the toothed plate 4. The backward blade 32, in conjunction with the cutting groove, can cut the melon vines and transfer them to the guide plate 6. The cut melon vines and other impurities carried along can be transported along the guide plate 6 to the front discharge assembly and discharged uniformly from one side of the harvester.

[0039] Each cleaning scraper 5 is fixedly welded to the assembly tube 52, and both ends of the assembly tube 52 can be stably installed on the mounting frame 11 by bolt assembly. The cleaning scraper 5 can remove the impurities attached to the cutting shaft 2, and the bent section 51 at its end can avoid the cutting shaft 2, so as to avoid spatial movement interference between the two.

[0040] To ensure that the forward blade 31 and the backward blade 32 can be stably installed on the cutting shaft 2 and evenly distributed, the following technical solution is provided.

[0041] Multiple sets of connecting rings 33 are fixedly connected to the cutting shaft 2, which are evenly distributed along the axis of the cutting shaft 2. Each set of connecting rings 33 is fixedly equipped with a forward blade 31 and a backward blade 32. A rectangular plate 321 is fixedly installed on the front side of the backward blade 32. The forward blades 31 and the backward blades 32 arranged on the same connecting ring 33 are arranged in a ring array.

[0042] Each connecting ring 33 is equipped with two sets of forward blades 31 and one set of backward blades 32. The three sets of blades are arranged in a ring array. The forward blades 31 and backward blades 32 are not sharp structures to avoid cutting the melon vines directly and affecting the transmission of the melon vines to the guide plate 6.

[0043] The rectangular plate 321 at the front end of the backward blade 32 can cooperate with the toothed groove in the toothed plate 4 to achieve effective cutting of the melon vine.

[0044] To ensure that the long toothed roller 12 can effectively transfer the melon vines it carries to the vine cutting assembly when it is running with the harvester, and that the vine cutting shaft 2 and the forward blade 31 and backward blade 32 on it cooperate with the toothed plate 4 to achieve efficient cutting of the melon vines, the following technical solution is provided for this air cylinder.

[0045] It also includes a guide rake 7 fixedly installed on the mounting frame 11 and arranged between the long toothed roller 12 and the cutting shaft 2. The guide rake 7 includes an assembly beam 71 and an arc-shaped rake rod 72 uniformly fixed to the assembly beam 71. The arc-shaped rake rod 72 is bent toward the long toothed roller 12. The long teeth provided on the long toothed roller 12, as well as the forward blade 31 and the backward blade 32, all run in the gap of the arc-shaped rake rod 72.

[0046] The assembly beam 71 in the guide rake 7 can be fixedly installed on the mounting frame 11 by bolt assembly, thereby ensuring the stable installation of the guide rake 7. The bottom of the arc-shaped rake rod 72 extends to the root of the long tooth in the long tooth roller 12. When the long tooth roller 12 drives the melon vine to rotate, the melon vine is guided by the arc-shaped rake rod 72 to move towards the top of the arc-shaped rake rod 72, and is then captured by the forward blade 31 provided on the vine cutting shaft 2. It is dragged by the forward blade 31 and passes through the cleaning scraper 5 and moves to the guide plate 6 and the toothed plate 4.

[0047] To ensure that the melon vines and other impurities cut by the vine-cutting assembly and transferred to the guide plate 6 can be effectively transported to the slag discharge assembly in front, the following technical solution is provided.

[0048] A rotating shaft 81 is rotatably mounted on the mounting frame 11 and arranged above the guide plate 6. A rotating plate 82 that is in contact with the upper surface of the guide plate 6 is fixedly mounted on the rotating shaft 81. The cutting shaft 2 is connected to the rotating shaft 81 in a transmission manner.

[0049] Ball bearings are installed at corresponding positions on the mounting frame 11, and both ends of the cutting shaft 2 and the turning shaft 81 are installed in the corresponding ball bearings to ensure the stable operation of the cutting shaft 2 and the turning shaft 81.

[0050] The rotating shaft 81 is provided with two sets of rotating plates 82 arranged in the same diameter direction. During the operation of the cutting shaft 2, it can drive the rotating shaft 81 and the rotating plates 82 on it to operate stably. With the help of the rotating plates 82, the melon seedlings cut on the guide plate 6 can be transferred to the debris removal component 13 set on the front side.

[0051] To ensure that the cutting shaft 2 can be stably connected to an external power source and to achieve coordinated operation between the cutting shaft 2 and the rotating shaft 81, so as to realize the effective cutting and transmission of melon vines, the following technical solution is provided.

[0052] The end of the cutting shaft 2 is coaxially fixed with drive sprocket A21 and drive sprocket B22. Drive sprocket A21 is connected to an external power source through a chain. The end of the flipping shaft 81 is coaxially fixed with transmission sprocket 83. Guide sprocket 111 is rotatably mounted on the mounting frame 11. Drive sprocket B22, transmission sprocket 83, and guide sprocket 111 are connected through a chain.

[0053] The external power source is provided by the internal combustion engine of the agricultural tractor. A drive shaft can be installed on the mounting frame 11. The drive shaft is connected to the output shaft of the agricultural tractor and a sprocket is installed on the drive shaft. It is chain driven with the drive sprocket A21 to ensure that the external power source can be stably transmitted to the drive sprocket A21 through the drive shaft, thereby driving the cutting shaft 2 to operate stably.

[0054] When the cutting shaft 2 is running, it can drive the rotating shaft 81 to run stably through the combination of drive sprocket B22, transmission sprocket 83 and guide wheel. The setting of guide sprocket 111 can ensure that the combination of chain and transmission sprocket 83 has a sufficient wrap angle, thereby ensuring the stable transmission of power to transmission sprocket 83.
