Description

Technical Field

[0001] This application relates to the technical field of harvesting equipment, and particularly relates to a crawler self-propelled corn harvesting equipment for harvesting both ears and stalks. Background Art

[0002] In the field of agricultural harvesting, for example, most corn harvesting equipment uses wheeled harvesters for harvesting operations. However, during actual operations, although they are convenient to operate and have good road passability, wheeled harvesters exert a large pressure on the ground and are not suitable for rough, soft, and muddy terrains. Not only may situations such as slipping occur, but they may also damage the soil structure.

[0003] Therefore, in the prior art, crawler-type harvesting equipment has begun to appear for harvesting crops. For example, Chinese invention patent CN116806537A, a crawler ear and stalk combined corn harvester, and Chinese invention patent CN115226486A, a crawler ear and stalk combined corn harvester. Both of these patents mention crawler-type harvesting equipment, but these harvesting equipment all use horizontal cutting platforms. The structure of the horizontal cutting platform is relatively complex, and the costs of disassembly, assembly, and maintenance are relatively high. It is difficult to apply to narrow terrains, and it is easy to damage crop grains. Moreover, in the prior art, the connection between the cutting platform and the crawler equipment is often not specifically described, and the applicability of the crawler equipment is also poor.

[0036] As Figures 1 to 6 shown, this application provides a crawler self-propelled corn harvester for both ear and stalk harvesting, including a header 10. The header 10 includes a main frame 101, a power unit 102, a ear picking unit 103, a straw shredding and feeding unit 104, a straw shredding and pneumatic conveying unit 105, and a straw conveying channel 106. The main frame is provided with a reciprocating straw cutter unit and a clamping chain feeding unit. The harvester further includes a crawler walking chassis 11 and a vehicle body 12. The vehicle body is arranged above the crawler walking chassis 11 and includes a peeling machine 124, a cab 121, and a material box 122. The ear picking unit 103 includes ear picking rollers 107. The ear picking rollers 107 are connected to the power unit 102 through a transmission device and are arranged in the vertical direction.

[0037] Among them, as Figure 1As shown in the figure, for the structure of the header 10, the ear stripper rolls 107 may include a first ear stripper roll 107 and a second ear stripper roll 107. The first ear stripper roll 107 and the second ear stripper roll 107 are respectively connected to the power unit 102 through a transmission device. The first ear stripper roll 107 and the second ear stripper roll 107 are arranged at intervals and are disposed in the vertical direction. The power unit 102 transmits power to the first ear stripper roll 107 and the second ear stripper roll 107. Further, the transmission device is a gearbox that transmits power or adjusts the direction. The input end of the power unit 102 is transmitted into the transmission device to complete the transmission, thereby driving the first ear stripper roll 107 and the second ear stripper roll 107 to rotate in the vertical direction, and jointly realizing the ear stripping action of the corn material through the first ear stripper roll 107 and the second ear stripper roll 107.

[0038] For the reciprocating straw cutter unit and the clamping chain feeding unit, they are arranged in the front-end area of the entire header. The reciprocating straw cutter unit cuts the straw of the crop, and the clamping chain feeding unit feeds it into the ear stripping unit for further work through the rotation and clamping of the clamping chain.

[0039] Further, the ear stripping unit 103, the straw chopping and feeding unit 104, and the straw chopping and pneumatic conveying unit 105 are integrally arranged on the main frame 101. After ear stripping, the straw enters the straw chopping and feeding unit 104 and is transported to the straw chopping and pneumatic conveying unit 105.

[0040] It should be noted that the equipment of the present application can realize the combined harvesting of the stems and ears of crops such as corn. For the specific structure of the header 10, there are already some similar structures of the header 10 in the prior art, so the present application will not be specifically described in detail here.

[0041] As a preferred embodiment of the present application, as Figure 3 shown, the crawler walking chassis 11 includes a drive wheel 112, a guide and tensioning wheel 111, a carrier wheel 115, a road wheel 114, and a walking track 113. The walking track 113 surrounds the road wheel 114, the carrier wheel 115, the guide and tensioning wheel 111, and the drive wheel 112. And the drive wheel 112 and the guide and tensioning wheel 111 are respectively arranged at both ends of the walking track 113, and the road wheel 114 and the carrier wheel 115 are arranged between the drive wheel 112 and the guide and tensioning wheel 111.

[0042] It can be understood that by setting the drive wheel 112 and the guiding and tensioning wheel 111 of the walking track 113 chassis at both ends of the walking track 113 respectively, the walking track 113 chassis can choose to perform rear drive or front drive to adapt to the connection and drive of different harvesting platforms 10. During rear drive, the drive wheel 112 serves as the main power drive part, which is arranged at the rear of the walking track 113, and the guiding and tensioning wheel 111 plays the role of supporting and tensioning the track. Of course, the drive wheel can also be arranged in front of the walking track to form front drive, so as to improve the applicability. In addition, by arranging a frame 15 between the vehicle body 12 and the track walking chassis 11, it plays the role of bearing and connecting. The power system arranged in the frame 15 can provide power for the harvesting platform 10 and the entire harvesting equipment, and the structure is more compact and integrated.

[0043] In a preferred embodiment, a frame 15 is arranged between the vehicle body 12 and the track walking chassis 11, and a power system is arranged in the frame 15. For the frame 15, it can play the role of bearing and connecting. For the power system, the power system of the track walking chassis 11 commonly used in the prior art can be adopted. For the structure and connection of the power system, no specific description is made in this application.

[0044] Since this application is directed to the cutting table 10 with the ear picking roller 107 arranged vertically, various different setting methods can be adopted for the structure setting of the cutting table 10. For example, for the setting methods and structures of the straw chopping and feeding unit 104 and the straw chopping and pneumatic conveying unit 105, there are different embodiments. Here, this application will illustrate with several prominent embodiments:

[0045] Embodiment 1:

[0046] In this embodiment, as Figure 2 and Figure 4 shown, the straw chopping and feeding unit 104 and the straw chopping and pneumatic conveying unit 105 are arranged in front of the frame 15 and in front of the cab 121. The straw chopping and feeding unit 104 is arranged in front of the straw chopping and pneumatic conveying unit 105, and the two are connected to each other. Extension frames 14 are arranged on the outer side walls of the straw chopping and pneumatic conveying unit 105 and the feeding shell, and the extension frames 14 are respectively connected to the cutting table 10 and the frame 15.

[0047] Arranging the straw chopping and feeding unit 104 and the straw chopping and pneumatic conveying unit 105 in front of the frame 15 can facilitate the installation and disassembly of the straw chopping and feeding unit 104 and the straw chopping and pneumatic conveying unit 105. And by arranging the extension frames 14, it can further make the cutting table 10 protrude from the frame 15, further facilitating assembly and disassembly, and making the integration degree of the equipment higher.

[0048] For the straw chopping and feeding unit 104, its front is connected to the ear picking unit 103, and the discharge port is directly connected to the straw chopping and pneumatic conveying unit 105, with a relatively high degree of integration. Through this embodiment, it is convenient to install and maintain the straw chopping and feeding unit 104 and the straw chopping and pneumatic conveying unit 105. The setting of the extension frame 14 enables the entire straw chopping and feeding unit 104 to protrude forward from the frame 15, facilitating the operation of the staff. Its power can be transmitted through the connection between the power system and the cutter bar 10. For the power transmission, reference can be made to the existing power transmission between the cutter bar 10 and the power system, and this application does not make specific limitations and descriptions on this.

[0049] Further, as Figure 4 shown, the material box includes a straw bin 1222 and a grain bin 1221. The straw bin 1222 and the grain bin 1221 are arranged left and right. The grain bin 1221 is arranged behind the peeling machine 124, and the straw bin 1222 is arranged below the end of the straw conveying channel. It can be understood that in this embodiment, the left and right arranged grain bin 1221 and straw bin 1222 respectively collect the chopped straw and peeled fruits. The straw bin 1222 and the grain bin 1221 can be set as structures that can be flipped left and right for unloading operations. And as Figure 4 can be seen, the longitudinally arranged peeling machine 124 means that the setting direction of the peeling rollers inside it is parallel to the traveling direction of the harvester. In this way, when the peeling rollers operate, the fruits can be transported backward along the traveling direction and transported into the grain bin 1221 behind the peeling machine 124.

[0050] Embodiment 2:

[0051] In this embodiment, compared with Embodiment 1, as Figure 5 and Figure 6 shown, the straw chopping and feeding unit 104 is arranged in front of the straw chopping and pneumatic conveying unit 105. The straw chopping and pneumatic conveying unit 105 and the straw chopping and feeding unit 104 share the same housing. The straw chopping and pneumatic conveying unit 105 is arranged below the cab 121 and in front of the frame 15. The fan pneumatic conveying unit 108 is arranged behind the straw chopping and pneumatic conveying unit 105 and inside the frame 15. Among them, a rotor rotating shaft 13 is arranged inside the straw chopping and pneumatic conveying unit 105. Both sides of the rotor rotating shaft 13 protrude from the outer side wall of the housing of the straw chopping and pneumatic conveying unit 105 and are connected to the frame 15 and the power system.

[0052] For this embodiment, a rotor rotating shaft 13 is arranged inside the straw chopping and pneumatic conveying unit 105. Both sides of the rotor rotating shaft 13 protrude from the outer side wall of the housing of the straw chopping and pneumatic conveying unit 105 to form mounting positions, directly positioning and fixing the straw chopping and feeding unit 104, without the need for the additional connection structure in Embodiment 1.

[0053] Moreover, in this embodiment, the material bin 122 includes a front and rear arranged grain bin 1221 and a straw bin 1222. The grain bin 1221 is arranged on one side of the peeling machine 124. That is to say, the grain bin 1221 and the peeling machine 124 are in a line, that is, they are arranged horizontally. By arranging the peeling machine 124 horizontally, that is, the length direction of the peeling roller in the peeling machine 124 is perpendicular to the traveling direction of the harvester, the peeling machine 124 can transport the fruits to the adjacent grain bin 1221 to realize the transportation of fruits. The straw bin 1222 is arranged behind the peeling machine 124 and the grain bin 1221, and the straw conveying channel 106 conveys the crushed straw to the straw bin 1222.

[0054] It can be understood that since the grain bin 1221 and the straw bin 1222 in this embodiment are arranged front and rear, the grain bin 1221 in the front can be set to flip to the side for unloading grain, and the straw bin 1222 in the rear can be set to flip backward for unloading grain according to needs, or can be set to flip to one of the left and right sides for unloading grain.

[0055] It should be noted that both embodiments of the present application can be set. For the convenience of understanding, the structure of the present application and Figures 1 to 4 are all described based on Embodiment 1. For Embodiment 2, the structure in which the straw chopping and pneumatic conveying unit 105 is arranged below the cab 121 and in front of the vehicle frame 15 and the structure in which the ear picking roller 107 is arranged vertically are various in the prior art, and its general structure can be referred to Figure 5 and Figure 6 , and the present application will not make specific descriptions here.

[0056] Furthermore, based on Embodiment 1, the harvesting equipment further includes a fruit elevator 123. One end of the fruit elevator 123 is connected to the cutting table 10, and the other end is arranged above the peeling machine 124. The material bin 122 is arranged at the rear end of the vehicle body 12 to receive the harvested fruits and the chopped straw. The structure is convenient and can realize the combined harvesting of stems and ears. For the specific structures of the fruit elevator 123, the straw chopping and pneumatic conveying unit 105, and the straw conveying channel 106, there are already detailed descriptions in the prior art, and the present application will not expand specifically here.

[0057] Each embodiment in this specification is described in a progressive manner. The same or similar parts between each embodiment can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0058] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
