Description

Technical Field

[0001] The utility model relates to the technical field of green fodder boxes, in particular to a secondary lifting, sliding and positioning structure of a box for a green fodder harvester. Background Art

[0002] Green fodder harvesters are used to harvest silage crops such as corn and grass in the field, and at the same time cut the crops into sections, rub them, crush the grains, and finally throw them to the following material vehicle. During the green fodder harvesting process, the lifting and sliding positioning of the feed box are of great significance to improving the harvesting efficiency and quality. Among them, the "Green fodder harvester feed box and green fodder harvester" disclosed by the authorization number "CN209030599U" has solved the problem that there is no unloading and conveying structure in the feed box of the existing green fodder harvester. When unloading the grain, the unloading angle of the feed box must be greater than the repose angle of the material to ensure that the feed box can unload the material into the grass transport vehicle. However, when unloading the grain, the larger the unloading angle of the feed box, the more the feed box is rotated out of the body, and the lower the safety. Further search revealed that the "A Green Forage Harvester Gearbox Transmission Structure" disclosed by the authorization number "CN220000085U" has effectively solved the technical disadvantages of the existing technology such as the scattered and complicated layout of the speed adjustment of the feeding roller and the forward and reverse switching of the green forage harvester, which makes maintenance difficult, through a specific technical structure setting. However, in actual use, a secondary lifting and sliding positioning structure of the material box for a green forage harvester with a similar structure still has many defects, such as: most of the existing green forage harvesting material boxes lack a secondary lifting mechanism, which reduces the green forage harvesting efficiency, and lacks a stabilizing mechanism during the lifting process, resulting in shaking and instability in the lifting, so it is necessary to design a secondary lifting and sliding positioning structure for the material box of a green forage harvester. Utility Model Content

[0003] The purpose of the utility model is to provide a secondary lifting and sliding positioning structure for a material box of a green fodder harvester, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a secondary lifting and sliding positioning structure of a material box for a green fodder harvester, comprising a green fodder harvesting material box main body shell, a lifting connecting block and a lifting support rod, the lifting connecting blocks are fixedly installed on both sides of the front end and the rear end of the green fodder harvesting material box main body shell, the lifting connecting rod is rotatably installed on the bottom of the lifting connecting block, the lifting support rod is slidably installed on the outer side of the lifting connecting rod, a lifting sliding groove is opened on the inner side of the lifting support rod, the lifting connecting rod slides inside the lifting sliding groove, a top support fixing plate is fixedly installed on the top of the lifting support rod, and a positioning seat bearing block rod is fixedly connected to the top of the top support fixing plate, a support sliding groove is opened on the side where the positioning seat bearing block rods are close to each other, and the lifting connecting rod is slidably installed inside the support sliding groove.

[0005] When the main shell of the green fodder harvesting box needs to be lifted a second time, the lifting connecting rod slides inside the lifting sliding groove, and the connection between the lifting connecting rod and the lifting connecting block drives the main shell of the green fodder harvesting box to perform a second lifting adjustment, so that the main shell of the green fodder harvesting box is adjusted to an appropriate height, and the positioning seat bearing stop rod is fixedly installed on the top of the lifting support rod through the top support fixing plate. At this time, when the lifting connecting rod slides inside the lifting sliding groove inside the lifting support rod, the lifting connecting rod slides inside the support sliding groove, thereby making the lifting and adjustment of the lifting connecting rod more stable, thereby making the lifting and adjustment of the main shell of the green fodder harvesting box more stable, improving the adjustment stability of the main shell of the green fodder harvesting box, making the main shell of the green fodder harvesting box more stable for green fodder harvesting operations, and facilitating the staff to perform secondary lifting and adjustment.

[0006] Preferably, a lifting positioning and fixing washer is movably mounted on the bottom of the inner side of the lifting connecting rod, and fixing bolts are rotatably mounted on the top and bottom of the lifting positioning and fixing washer. A through hole is formed at the bottom of the lifting connecting rod, and positioning threaded holes are evenly formed on the inner wall of the lifting sliding groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By providing a lifting connection block, a lifting support rod, a lifting sliding groove and a lifting connection rod, when the main shell of the green fodder harvesting material box needs to be lifted for a second time, the lifting connection rod slides inside the lifting sliding groove, and the connection between the lifting connection rod and the lifting connection block drives the main shell of the green fodder harvesting material box to perform a second lifting adjustment, so that the main shell of the green fodder harvesting material box is adjusted to an appropriate height, which is convenient for the green fodder harvesting material box main shell to recover green fodder.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the utility model proposes a secondary lifting and sliding positioning structure of a material box for a green fodder harvester, comprising a green fodder harvesting material box main body shell 1, a lifting connecting block 101 and a lifting support rod 102. The lifting connecting blocks 101 are fixedly installed on both sides of the front end and the rear end of the green fodder harvesting material box main body shell 1, and a lifting connecting rod 104 is rotatably installed on the bottom of the lifting connecting block 101. A lifting support rod 102 is slidably installed on the outer side of the lifting connecting rod 104. A lifting sliding groove 103 is provided on the inner side of the lifting support rod 102. The lifting connecting rod 104 slides inside the lifting sliding groove 103. A top support fixing plate 105 is fixedly installed on the top of the lifting support rod 102, and a positioning seat bearing retaining rod 106 is fixedly connected to the top of the top support fixing plate 105.

[0024] A support sliding groove 107 is provided on the side where the positioning seat bearing stop rods 106 are close to each other, and the lifting connecting rod 104 is slidably installed inside the support sliding groove 107, and a lifting positioning fixing gasket 108 is movably installed at the bottom of the inner side of the lifting connecting rod 104, and the top and bottom of the lifting positioning fixing gasket 108 are rotatably installed with fixing bolts 109, and a through hole 2 is provided at the bottom of the lifting connecting rod 104, and positioning threaded holes 201 are evenly provided on the inner wall of the lifting sliding groove 103, and the fixing bolts 109 extend through the through hole 2 through the thread to the inside of the positioning threaded hole 201, and the outer wall of the lifting support rod 102 is fixedly installed with a supporting leg main rod 3, and the bottom of the supporting leg main rod 3 is fixedly connected to the supporting foot sole 301, and the top of the supporting foot sole 301 is fixedly installed with a triangular support block 302, and the triangular support block 302 is fixedly connected to the inner wall of the supporting leg main rod 3.

[0025] The working principle of the secondary lifting and sliding positioning structure of the feed box for a green fodder harvester based on Example 1 is as follows: first, the supporting leg main rod 3 and the supporting foot sole 301 support the lifting support rod 102, thereby supporting the green fodder harvesting material box main body shell 1 through the lifting support rod 102, so that the green fodder harvesting material box main body shell 1 can be more stably used for green fodder harvesting operations, and the triangular support block 302 is fixed to the corner of the supporting leg main rod 3 and the supporting foot sole 301. Due to the triangular structure of the triangular support block 302, the supporting leg main rod 3 and the supporting foot sole 301 are supported more firmly, so that the green fodder harvesting material box main body shell 1 can be more stably used for green fodder harvesting operations;

[0026] When the main body shell 1 of the green fodder harvesting material box needs to be lifted for the second time, the lifting connecting rod 104 slides inside the lifting sliding groove 103, and the connection between the lifting connecting rod 104 and the lifting connecting block 101 drives the main body shell 1 of the green fodder harvesting material box to perform a second lifting adjustment, so that the main body shell 1 of the green fodder harvesting material box is adjusted to an appropriate height, and the positioning seat bearing stopper rod 106 is fixedly installed on the top of the lifting support rod 102 through the top support fixing plate 105. At this time, when the lifting connecting rod 104 slides inside the lifting sliding groove 103 inside the lifting support rod 102, the lifting connecting rod 104 slides inside the supporting sliding groove 107, so that the lifting and lowering adjustment of the lifting connecting rod 104 is more stable, thereby making the lifting and lowering adjustment of the main body shell 1 of the green fodder harvesting material box more stable, thereby improving the adjustment stability of the main body shell 1 of the green fodder harvesting material box;

[0027] The green fodder harvesting box main body shell 1 makes the green fodder harvesting operation more stable, and is convenient for the staff to perform secondary lifting and adjustment. When the lifting connecting rod 104 slides to a suitable height inside the lifting sliding groove 103, the fixing bolt 109 passes through the lifting positioning fixing gasket 108 and the through hole 2, and extends to the inside of the positioning threaded hole 201 through threaded rotation, so that the lifting connecting rod 104 is fixedly installed at a suitable height inside the lifting sliding groove 103, thereby fixing the green fodder harvesting box main body shell 1 at a suitable height.
