Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery and equipment, and in particular to a grain collecting arrangement of a harvester suitable for large-plot operations. Background Art
[0002] With the large-scale planting of corn and the rapid development of agriculture and animal husbandry, the stalk and ear harvester has emerged and is widely used. The stalk and ear harvester can harvest both corn ears and corn stalks, so the stalk and ear harvester is generally equipped with an ear box for collecting ears and a straw box for collecting straw. The straw is very large, so the straw box on the stalk and ear harvester is generally larger than the stalk box.
[0003] The current stalk-and-ear harvesters are limited by many factors (road accessibility, field accessibility, body structure, etc.) and cannot be made very large. Therefore, the ear boxes they are equipped with cannot be made very large. When operating in large plots of land in the northwest and northeast, they need to stop and unload grain frequently, which seriously affects operating efficiency.
[0004] In addition, stalk-and-ear harvesters usually work alone when operating on small plots, and usually follow a vehicle when operating on large plots (meaning a trailer follows the harvester to collect straw). When following a vehicle, the large-volume straw box is empty and cannot collect straw. In this case, unloading grain depends on the fullness of the ear box. Since the volume of the ear box is generally small, the machine still needs to stop frequently to unload grain when operating on large plots, which seriously affects the working efficiency.

[0038] The following is combined with Figure 1 To Attachment Figure 3 , some embodiments of the present utility model are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0039] The utility model provides a grain collecting arrangement of a harvester suitable for large plots of land, such as Figures 1 to 3 As shown, it includes a peeling machine module 1, a fruit ear box 2 and a large-volume grass box 3; the peeling machine module 1, the fruit ear box 2 and the large-volume grass box 3 are arranged in sequence, so that the fruit ears can pass through the peeling machine module 1, the fruit ear box 2 and the large-volume grass box 3 in sequence; a transmission mechanism 4 is arranged in the fruit ear box 2, which is used to transport the fruit ears entering the fruit ear box 2 to the large-volume grass box 3.
[0040] In this embodiment, after the fruit ears are peeled by the peeling machine module 1, the fruit ears enter the fruit ear box 2, and are transported to the large-volume straw box 3 through the transmission mechanism 4. Since the volume of the large-volume straw box 3 is larger than that of the conventional straw box, it can accommodate more fruit ears, does not require frequent loading and unloading, reduces the number of unloading times, and improves work efficiency.
[0041] In a preferred embodiment, the transmission mechanism 4 is a belt transmission device or a chain transmission device.
[0042] In this embodiment, the fruit ears entering the fruit ear box 2 are transported to the large-capacity straw box 3 by throwing through a belt transmission device or a chain transmission device.
[0043] It can be understood that the transmission mechanism can be any one of the above two structures, but it is not limited to the above two structures. It can also be other structures. That is to say, as long as it can have the function of fruit ear transmission and can transmit the fruit ears to the large-volume grass box 3, it can be sufficient.
[0044] In a preferred embodiment, the transmission mechanism 4 includes a pulley 5, a power device, a transmission frame and a transmission belt 6; the number of the pulleys 5 is two, and the two pulleys 5 are rotatably set on the transmission frame, and the transmission belt 6 is wound around the pulley 5; a plurality of baffles 7 are provided on the transmission belt 6, and the baffles 7 are arranged in parallel and at intervals along the moving direction of the transmission belt 6, and are used to push the fruit ears on the transmission belt 6 toward the large-volume grass box 3; the power device is connected to any one of the pulleys 5, and is used to drive the pulley 5 to rotate.
[0045] Specifically, in this embodiment, one of the two pulleys 5 is arranged inside the fruit ear box 2, and the other is arranged outside the fruit ear box 2, that is, above or above the large-volume grass box 3, so that the fruit ears on the transmission belt 6 can be transported to the large-volume grass box 3.
[0046] More specifically, in this embodiment, the power device is connected to one of the pulleys 5 so that it serves as a driving pulley and the other pulley 5 serves as a driven pulley. A plurality of baffles 7 are provided on the transmission belt 6 to divide the outer surface of the transmission belt 6 into a plurality of sections, each of which can exert thrust on the fruit ears, thereby facilitating the throwing of the fruit ears into the large-capacity grass box 3.
[0047] In this embodiment, the height of the baffle 7 can be set according to the actual moving track. When the conditions are met, the higher the height of the baffle 7 is, the more fruit ears the transmission belt 6 can transport.
[0048] In a preferred embodiment, the transmission frame includes a fixed frame 9 and a lifting frame 10, the height of the lifting frame 10 is greater than the height of the fixed frame 9; the lifting frame 10 and the fixed frame 9 are respectively connected to the two pulleys 5; the height of the lifting frame 10 can be raised and lowered to adjust the pitch angle of the transmission belt 6.
[0049] In this embodiment, one end of the transmission frame is set as a lifting frame 10, which can change the pitch angle of the transmission belt 6 by lifting, thereby changing the landing point of the fruit ears in the large-volume grass box 3, so that the fruit ears entering the large-volume grass box 3 can be more uniform, and the capacity of the large-volume grass box 3 can be further effectively increased.
[0050] In this embodiment, the lifting and lowering of the lifting frame 10 can be adjusted manually or automatically.
[0051] When it is automatically adjusted, it can be adjusted in a continuous up and down swinging manner, that is, the continuous up and down swinging of the lifting frame 10 is realized by setting a cam or a crank slider structure; it can also be adjusted according to the storage situation of the fruit ears in the large-volume grass box 3, that is, when the sensor senses that the height of the fruit ears at the proximal end of the large-volume grass box 3 is higher, the height of the lifting frame 10 is increased to throw the fruit ears to the far end of the large-volume grass box 3.
[0052] In a preferred embodiment, the lifting frame 10 includes a lifting base frame and a telescopic frame; the lifting base frame is fixedly arranged in the fruit ear box 2, one end of the telescopic frame is fixedly connected to the lifting base frame, and the other end is connected to the pulley 5.
[0053] In this embodiment, the lifting chassis is fixed inside the ear box 2, which may be the bottom or the side wall, as long as the lifting chassis can be fixed.
[0054] In this embodiment, one end of the transmission belt 6 is driven to rise and fall by the extension and retraction of the telescopic frame.
[0055] In a preferred embodiment, the telescopic frame is at least one of a gear rack structure, a threaded screw structure, and a scissor-type telescopic structure.
[0056] Specifically, in this embodiment, the telescopic frame can be one of the structures, such as a gear rack structure, which is connected to a transmission rack at both ends of the pulley 5, the transmission gear is meshed with the transmission rack, and the power motor drives the transmission gear to rotate and further drives the transmission rack to move linearly in the up and down directions, so as to realize the lifting function of one end of the transmission belt 6.
[0057] It is understandable that the above structure also needs to be coordinated with a guiding device for guiding, a structure for improving stability, etc.
[0058] In this embodiment, the telescopic frame can also be driven by a threaded screw structure, or by a scissor-type telescopic structure, both of which can achieve telescopic movement of the telescopic frame, thereby achieving angle adjustment of the transmission belt 6.
[0059] It can be understood that in this embodiment, the structure of the lifting frame 10 can be any one of them, and it can also be a combination of two types, such as combining a scissor-type telescopic structure with a threaded screw structure, that is, it has the rapid telescopic function of the scissor-type telescopic structure and the precise adjustment function of the bolt and screw structure.
[0060] In a preferred embodiment, the transmission frame also includes a bracket 8, both ends of which are rotatably connected to the fixed frame 9 and the lifting frame 10 respectively, the pulleys 5 are respectively arranged at both ends of the bracket 8, and the transmission belt 6 is wound around the outside of the bracket 8.
[0061] In this embodiment, a bracket 8 is arranged on the upper part of the transmission frame, the bracket 8 is surrounded by the transmission belt 6, and pulleys 5 are arranged at both ends of the bracket 8. At this time, the pitch angle of the transmission belt 6 can be adjusted by adjusting the pitch angle of the bracket 8.
[0062] With this arrangement, the lifting frame 10 can be arranged inside the fruit ear box 2, that is, the lifting frame 10 is connected to the middle part of the bracket 8 or the side of the middle part close to the large-volume grass box 3, so that the transmission belt 6 can be extended farther and the fruit ears can be transported into the large-volume grass box 3 more accurately. At the same time, the lifting frame 10 is also protected to a certain extent, reducing the impact of the external environment on the lifting frame 10.
[0063] In a preferred embodiment, a tensioning wheel structure is further provided on the transmission frame. The tensioning wheel structure is arranged inside the ring of the transmission belt 6 and is used to tighten the transmission belt 6 .
[0064] In this embodiment, the tensioner structure is disposed on the bracket 8 , and the stability of the transmission belt 6 can be ensured by disposing the tensioner structure.
[0065] Specifically, the tension wheel structure includes a distance adjusting device and a tension wheel. The distance adjusting device connects the tension wheel and the bracket 8 and is used to adjust the distance between the tension wheel and the bracket 8 , thereby achieving tensioning of the transmission belt 6 .
[0066] In a preferred embodiment, the power device is an electric motor.
[0067] In this embodiment, the power of the belt transmission is a motor, but it is not limited to a motor, it can also be other power devices, such as a cylinder, a hydraulic cylinder, etc., as long as it can provide power for the belt transmission.
[0068] In a preferred embodiment, an observation window is provided on the side wall of the fruit ear box 2 for observing the interior of the fruit ear box 2 .
[0069] In this embodiment, the observation window is provided to facilitate observation of the interior of the ear box 2, so that failures of the transmission mechanism 4 and the accommodation of the ears in the ear box 2 can be discovered in time, so that timely adjustments and maintenance can be performed.
