Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1 and Figure 2 As shown, the adjustable lifting and unloading mechanism for the peanut harvester of this utility model includes a base frame 1, a grain bin support 2, a grain bin sliding frame 3, and a grain bin 4. The grain bin support 2 is rotatably connected to the base frame 1. One side of the bottom of the grain bin support 2 is rotatably connected to the base frame 1, and the other side of the bottom of the grain bin support 2 is connected to a tilting cylinder 6, which enables the grain bin support 2 to rotate. A limiting part is also connected between the grain bin support 2 and the base frame 1 to limit the rotation angle of the grain bin support 2.

[0019] The grain storage sliding frame 3 is set vertically and is slidably connected to the grain storage support 2. The grain storage sliding frame 3 and the grain storage support 2 are connected by a secondary lifting cylinder 5.

[0020] The top of the grain bin 4 is rotatably connected to the top of the grain bin sliding frame 3. Initially, the grain bin 4 is housed within the grain bin support 2. The grain bin 4 and the grain bin sliding frame 3 are connected via a grain unloading cylinder 7.

[0021] like Figure 3 As shown, the base frame 1 includes a rectangular base tube frame 101, which is composed of four base tubes connected end to end. Adjacent base tubes are vertically fixed together, and a base frame fixing plate 106 is provided at each vertical fixed connection point, thereby increasing the connection strength between adjacent base tubes. Two sets of grain silo support connecting plates are fixed at both ends of one side of the base tube frame 101 along its length. Each set of grain silo support connecting plates includes two opposing grain silo support connecting plates 103, with a certain distance between the two grain silo support connecting plates 103. The grain silo support connecting plates 103 enable a rotatable connection between the base frame 1 and the grain silo support. Limiting connecting plates 102 are provided at both ends of the other side of the base tube frame 101 along its length, enabling a connection between the base frame 1 and the limiting part.

[0022] A sequence valve fixing plate 105 is fixed to the outside of the bottom pipe rack 101, and the first sequence valve 10 is mounted on the sequence valve fixing plate 105. The bottom pipe rack 101 is also provided with an oil pipe fixing plate 104, and the oil pipe is wound around the oil pipe fixing plate 104 to fix the oil pipe.

[0023] like Figure 4As shown, the grain silo support 2 is L-shaped, including an upper crossbeam 201, a first bottom beam 210, and a second bottom beam 215. The upper crossbeam 201 is located directly above the first bottom beam 210, and the upper crossbeam 201 and the first bottom beam 210 are fixedly connected by two vertically arranged columns 216. The upper crossbeam 201 and the first bottom beam 210 are connected to form a rectangular vertical frame. To improve the connection strength between the upper crossbeam 201 and the first bottom beam 210, several reinforcing columns 214 are also connected between the upper crossbeam 201 and the first bottom beam 210.

[0024] The first bottom beam 210 and the second bottom beam 215 are located on the same horizontal plane. The two ends of the first bottom beam 210 and the second bottom beam 215 are fixedly connected by connecting rods, thus forming a rectangular horizontal frame. To improve the connection strength between the vertical frame and the horizontal frame, a reinforcing plate 205 is fixedly connected between the column 216 and the connecting rod. A diagonal bracing beam 207 is connected between the top of the upper horizontal beam 201 and the end of the corresponding lower second horizontal beam 215.

[0025] Each of the two uprights 216 has a slide rail 212 on its opposite side. The two side walls of the grain silo sliding frame 3 are slidably mounted in the slide rail 212. To reduce the friction between the uprights 216 and the grain silo sliding frame 3 during relative sliding, a first pulley 202 and a second pulley 213 are provided in the slide rail 212. To improve the support strength of the uprights 216, several reinforcing buckles 203 are fixed at intervals on the outer side of each upright 216 in the vertical direction.

[0026] Each column 216 has a rotating shaft 206 at its bottom. The bottoms of the two columns 216 are respectively located in the two sets of grain silo support connecting plates at both ends of the base frame, and are rotatably connected to the grain silo support connecting plate 103 through the rotating shaft 206.

[0027] The lower seat plate 203 of the secondary lifting cylinder is fixed in the middle of the first bottom beam 210, and the cylinder body of the secondary lifting cylinder is connected to the lower seat plate 203.

[0028] The upper seat plate 211 of the tilting cylinder is fixed in the middle of the second bottom beam 215. The cylinder body of the tilting cylinder 6 is connected to the main frame of the peanut harvester, and the piston rod of the tilting cylinder 6 is connected to the upper seat plate 211. During the operation of the tilting cylinder 6, it can drive the entire grain bin support 2 to rotate along the hinge point between the grain bin support and the base frame.

[0029] Two opposing support plates 208 are fixed at both ends of the second bottom beam 215. A guide plate 209 is fixed between the two support plates 208. The guide plate 209 has guide holes, which guide the limiting part.

[0030] like Figure 7As shown, the limiting part includes a limiting rod 901 and a limiting block 902 located at the top of the limiting rod. The top of the limiting rod 901 is rotatably connected to the limiting part connecting plate 102. The limiting rod 901 passes through a guide hole on the guide plate 209, and the limiting block 902 is located above the guide plate 209. During the rotation of the grain bin support 2 driven by the tilting cylinder 6, the second bottom beam 215 moves upward. When the guide plates 209 at both ends of the second bottom beam 215 move to contact the limiting block 902, the second bottom beam 215 cannot continue to rotate due to the obstruction of the limiting block 902, thereby preventing the tilting cylinder 6 from overtraveling and causing damage to the entire machine.

[0031] like Figure 5 As shown, the grain silo sliding frame is arranged vertically and includes two vertically arranged support pipes 301, and an upper connecting pipe 303 and a lower connecting pipe 309 connecting the two support blocks 301. The two support pipes 301 are slidably arranged in the slide rail 212. To improve the rigidity of the entire frame, oblique reinforcing pipes 308 are fixedly connected between the two support pipes and the lower connecting pipe 309. To reduce the friction generated during the relative sliding of the support pipes 301 and the slide rail 212, rollers 302 are provided at the bottom and sides of the support blocks 301.

[0032] The top of each of the two support blocks 301 is provided with a connecting sleeve 305. Through the connecting sleeve 305 and the rotating shaft set in the connecting sleeve, the rotational connection between the grain storage sliding frame 3 and the grain storage 4 is realized.

[0033] A secondary lifting cylinder upper seat plate 304 is fixed in the middle of the upper connecting pipe 303. The cylinder body of the secondary lifting cylinder 5 is connected to the secondary lifting cylinder lower seat plate 204 set on the grain silo support 2, and the piston rod of the secondary lifting cylinder 5 is connected to the secondary lifting cylinder upper seat plate 304. The connection between the grain silo support 2 and the grain silo sliding frame 3 is realized through the secondary lifting cylinder 5. During the operation of the secondary lifting cylinder 5, the height of the grain silo sliding frame 3 and the grain silo 4 is adjusted by adjusting the length of the piston rod.

[0034] The lower connecting pipe 309 has a lower seat plate 310 for unloading oil cylinder fixed in the middle, and the grain bin sliding frame 3 and the grain bin 4 are connected by the unloading oil cylinder 7.

[0035] Meanwhile, a second sequence valve 307 is also provided on the lower connecting pipe 309. The first sequence valve 10 and the second sequence valve 307, as provided in this application, control the sequence of action of the tilting cylinder 6 and the unloading cylinder 7 during the grain unloading and receiving processes. When the mechanism performs the grain unloading action, the tilting cylinder 6 actuates first. After the piston rod of the tilting cylinder 6 extends to its position, the unloading cylinder 7 actuates next. The sequence of action of the tilting cylinder 6 and the unloading cylinder 7 during this process is controlled by the first sequence valve 10. When the unloading action of the mechanism ends and it needs to return to the initial state, the unloading cylinder 7 actuates first. After the piston rod of the unloading cylinder 7 retracts to its position, the tilting cylinder 6 actuates next. The sequence of action of the unloading cylinder 7 and the tilting cylinder 6 during this process is controlled by the second sequence valve 307.

[0036] like Figure 6 As shown, the grain silo includes a grain silo panel 401. The grain silo panels located on the four sides and the bottom together form a cavity for the grain silo panel, and the top of the grain silo panel has an opening. The grain silo has an internal frame 406, which provides support for the grain silo. The sides of the grain silo facing the grain silo sliding frame 3 have two vertically arranged side connecting frames 407 and several horizontally arranged side connecting frames 403 connecting the two vertically arranged side connecting frames.

[0037] The topmost side connecting frame has connecting lugs 404 fixed at both ends. These lugs 404 are connected to connecting sleeves 305 at the top of the grain silo sliding frame via rotating shafts, thus achieving a rotatable connection between the grain silo 4 and the grain silo sliding frame. A grain unloading cylinder upper seat plate 402 is also fixed in the middle of the side connecting frame. The cylinder body of the grain unloading cylinder 7 is connected to the grain unloading cylinder lower seat plate 310 on the grain silo sliding frame, and the piston of the grain unloading cylinder 7 is connected to the grain unloading cylinder upper seat plate 402. During operation, the grain unloading cylinder 7 drives the grain silo 4 to rotate along the rotatable connection between the grain silo and the grain silo sliding frame. When unloading is required, the piston rod of the grain unloading cylinder 7 extends, causing the grain silo 4 to flip, rotating from a vertical direction to a downward-sloping direction. At this time, the harvested peanuts inside the grain silo can flow out from the side opening, thus unloading the peanuts.

[0038] This mechanism enables grain unloading both at a constant height and at a height. For example... Figure 8As shown, when the transport vehicle is a small tricycle, due to the low height of the tricycle, the mechanism can unload grain directly without increasing its height. At this time, the secondary lifting cylinder 5 does not operate, while the unloading cylinder 7 operates, extending its piston rod and causing the grain bin 4 to rotate around the connection between the grain bin and the sliding frame, turning the grain bin 4 from a vertical to a horizontal position. Simultaneously, the tilting cylinder 6 operates, causing the grain bin support 2 to rotate around its connection with the base frame 1. During the rotation of the grain bin support 2, the grain bin 4 rotates counterclockwise via the sliding frame 3. During this counterclockwise rotation, the opening of the grain bin tilts downwards, making it easier for the peanuts inside to be unloaded onto the small tricycle. During the rotation of the grain bin support 2, the rotation angle is limited by the limiting part 2, ensuring both the smooth unloading of the peanuts and the overall safety of the mechanism.

[0039] like Figure 7 As shown, when the transport vehicle is a large truck with a relatively high height, the mechanism needs to raise the unloading height. At this time, the secondary lifting cylinder 5, the tilting cylinder 6, and the unloading cylinder 7 operate simultaneously: the piston rod of the secondary lifting cylinder 5 extends, and as the grain silo sliding frame 3 slides upward along the grain silo support 2, it also raises the height of the grain silo 4; the piston rod of the unloading cylinder 7 extends, causing the grain silo 4 to tilt from a vertical direction to a horizontal direction; the piston rod of the tilting cylinder 6 extends, causing the grain silo support 2 to rotate, causing the opening of the grain silo 4 to tilt downwards, facilitating the unloading of peanuts from the grain silo. In this application, the extension length of the piston rod of the secondary lifting cylinder 5 can be adjusted according to the height of the vehicle, making the mechanism applicable to transport vehicles of various heights.
