[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] The invention provides a small harvester suitable for harvesting in different intercropping sowing modes.

[0051] First embodiment:

[0052] Please combine Figures 1 to 8 , a small harvester suitable for harvesting in different intercropping sowing modes, comprising a mounting plate 1, a driving mechanism 3, a conveying mechanism 4 and a soybean cutting mechanism 5;

[0053] Two mounting seats 11 are fixedly provided on the outer wall of the mounting plate 1, and a cutting frame 2 is rotatably connected to the opposite side of the two mounting seats 11, and an auxiliary wheel 14 is rotatably connected to the middle position of the bottom of the cutting frame 2, and a positioning frame 12 is fixedly provided on the upper surface of the cutting frame 2, and a driving motor 13 is installed inside the positioning frame 12 by bolts;

[0054] See also Figure 2 and Figure 3 : When the cutting frame 2 is moving forward, if the ridge-forming part at the bottom of the cutting frame 2 is raised, the auxiliary wheel 14 will rise along with the ridge height, thereby controlling the entire cutting frame 2 to flip in a circle along the hinge position of the mounting seat 11, thereby controlling the entire cutting frame 2 to rise and preventing the cutting frame 2 from colliding with the raised part on the ridge.

[0055] The driving mechanism 3 includes a protective shell 31, and a driving pulley 32 and a driven pulley 33 are rotatably connected to the inner surface of the protective shell 31 and the upper surface of the cutting frame 2, and a first gear 34 is fixed to the lower surface of the driven pulley 33, and a driving belt 36 is sleeved on the outer wall of the driving pulley 32 and the driven pulley 33, and a second gear 35 is meshed and connected to one side of the first gear 34;

[0056] See also Figure 2 and Figure 4 : Since the intercropping mode requires cutting of soybeans, the user can start the drive motor 13 to control the drive pulley 32 to rotate in the protective shell 31.

[0057] The conveying mechanism 4 includes an inner plate 41 fixedly mounted on the inner wall of the cutting frame 2, and the number of the inner plates 41 is two, the upper surfaces of the two inner plates 41 are rotatably connected with a first pulley 42 and a second pulley 43, the outer walls of the first pulley 42 and the second pulley 43 are sleeved with a conveying belt 44, and the outer wall of the conveying belt 44 is fixedly mounted with a plurality of conveying rods 45;

[0058] The soybean cutting mechanism 5 includes a shield 51 fixedly mounted on the lower surfaces of the two inner plates 41, the inner part of the shield 51 is rotatably connected to a third pulley 52 and a fourth pulley 53, the outer walls of the third pulley 52 and the fourth pulley 53 are sleeved with a cutting belt 54, and a saw wheel 55 is installed at the axis of the fourth pulley 53 and in a key groove below the shield 51.

[0059] See also Figure 5When the driving pulley 32 rotates counterclockwise, the transmission driving belt 36 drives the driven pulley 33 to rotate counterclockwise, and the first gear 34 is bound to follow the driven pulley 33 to rotate counterclockwise, and the counterclockwise rotating first gear 34 engages and drives the second gear 35 to rotate clockwise. At this time, the driving pulley 32 and the second gear 35 control the two first pulleys 42 to rotate counterclockwise and clockwise, and the two first pulleys 42 drive the conveyor belt 44 to transmit movement. During the transmission process of the conveyor belt 44, the conveying rod 45 of the outer wall will be driven to move relative to each other, so that the soybean stalks entering through the cutting frame 2 will be sent toward the inside through the relatively moving conveying rod 45.

[0060] See also Figure 6 and Figure 7 : During the rotation, the first pulley 42 will synchronously drive the third pulley 52 at the bottom to rotate synchronously, and the transmission cutting belt 54 will control the rotation of the fourth pulley 53 at the same level, so that the rotation of the saw wheel 55 can be controlled. In this way, the transmission directions of the two saw wheels 55 and the two conveyor belts 44 are consistent, and the soybeans fed in will be cut by the staggered rotating saw wheels 55 to cut the soybean stalks.

[0061] The bottom axis of the driving motor 13 is keyed to the axis of the driving pulley 32, the axis of the second gear 35 is rotationally connected to the cutting frame 2, the axis of the second gear 35 and the driving pulley 32 are respectively keyed to the axis of the first pulley 42, and the axis of the second gear 35 is keyed to the axis of the first pulley 42 below.

[0062] The plurality of conveying rods 45 are equidistantly arranged on the outer surface of the conveying belt 44 , the conveying rods 45 are curved, and the front of the cutting frame 2 is triangular in design.

[0063] The axis of the first pulley 42 is keyed to the axis of the third pulley 52 , the axis of the fourth pulley 53 is rotatably connected to the two inner plates 41 , and the saw wheels 55 are staggered and fitted up and down.

[0064] It can be understood that the triangular-shaped cutting frame 2 can push all the soybean crops on the ridge through the inclined surface and finally concentrate them on the position of the conveying mechanism 4, thereby preventing omissions and facilitating concentrated cutting.

[0065] Preferably, the driving motor 13 can preferably be a double-headed motor.

[0066] Please combine again Figure 4 It can be seen that there are two groups of conveying mechanisms 4 and soybean cutting mechanisms 5, so that four rows or three rows of soybeans can be harvested.

[0067] This embodiment: Compared with the traditional soybean cutting method, this case improves the traditional distribution wheel. The conveying rod 45 on the outer wall is driven by the counterclockwise and clockwise relative rotation of the conveying belt 44 to move relative to each other, so that all the soybeans on the ridge can be clamped and transported. Compared with the traditional distribution, the clamping design has a greater force and a stronger drag force. Secondly, the soybeans can be well gathered between the two conveying rods 45. The integrated linkage saw wheel 55 is also conducive to the rapid cutting of the gathered soybean stalks. Secondly, the overall cutting frame 2 is designed to follow the ridge height. In this way, when encountering a high ridge position, there is no need to manually judge to lift the cutting frame 2. The cutting frame 2 can automatically change its height according to the ridge height.

[0068] Second embodiment:

[0069] See also Fig. 9 and Fig.10 , further comprising a frame 8;

[0070] A moving mechanism 9 is installed inside the frame 8, and the moving mechanism 9 includes a shell 91 installed on the upper surface of the frame 8, a moving motor 92 is installed on the upper surface of the frame 8 and inside the shell 91 through bolts, a power belt 93 is installed on the output shaft of the moving motor 92, a middle shaft 94 is installed at the bottom of the power belt 93, and moving wheels 95 are installed at both ends of the middle shaft 94, and a handrail 10 is installed on the side wall of the frame 8;

[0071] The moving wheel 95 forms a rotation transmission with the moving motor 92 through the transmission between the central shaft 94 and the power belt 93.

[0072] See also Fig. 9 : The cutting frame 2 moves forward through the forward movement of the frame 8. When the frame 8 needs to move forward, the user needs to start the mobile motor 92 to control the power belt 93 to rotate. The power belt 93 transmits power to the middle shaft 94. When the middle shaft 94 rotates, it will drive the moving wheels 95 on both sides to move on the field, so that the frame 8 can be driven forward or backward.

[0073] A corn cutting mechanism 6 is installed on the outside of the mounting plate 1 and on one side of the cutting frame 2. The corn cutting mechanism 6 includes a mounting frame 61. A front plate 62 is welded to the outer wall of the mounting frame 61. A slot 63 is opened inside the front plate 62. An electric chain saw 67 is installed inside the slot 63. A plurality of brackets 64 are installed on the outer wall of the front plate 62. A first distribution plate 65 and three second distribution plates 66 are installed on the top of the plurality of brackets 64 by bolts.

[0074] The first distribution plate 65 is longer than the second distribution plate 66 , and the first distribution plate 65 and the second distribution plate 66 are arranged obliquely in a triangle.

[0075] See also Fig.10 : Since soybeans are intercropped with corn, when the corn needs to be harvested, the mounting frame 61 will also move forward with the soybean cutting mechanism 5. At this time, the corn on the corn ridge will enter the first distribution plate 65 and the second distribution plate 66 in turn, and enter the electric chain saw 67 through distribution. The rotating electric chain saw 67 can cut the corn stalks. At the same time, the corn will be stored in the mounting frame 61 after cutting. As the mounting frame 61 continues to move forward, the cut corn will be exported through the gap between the second distribution plate 66 and the front plate 62. Therefore, the corn after cutting will be distributed behind the mounting frame 61 of the frame 8.

[0076] It can be understood that the notch 63 is provided to avoid interference between the electric chain saw 67 and the front plate 62. Secondly, the upper portion of the front plate 62 is provided obliquely so that the cut corn can be smoothly exported.

[0077] In this embodiment, the corn cutting mechanism 6 and the soybean cutting mechanism 5 are installed on a frame 8. The combined design is more conducive to the harvesting in the intercropping mode of soybeans and corn, and is convenient for separate harvesting. Secondly, the first dividing plate 65 in the corn cutting mechanism 6 directly extends to the position of the front plate 62 to isolate the corn and soybeans, which can prevent the corn from tipping to the side of the soybeans after the harvesting is completed. Secondly, a gap is set between the second dividing plate 66 and the front plate 62, so that when the corn is cut, it can be diagonally guided from the gap position along the top of the front plate 62 to the rear of the front plate 62, so that it falls on the ridge, which is more conducive to the harvesting in the intercropping mode.

[0078] Third embodiment:

[0079] See also Figure 2 and Fig.11 A feeding mechanism 7 is installed above the cutting frame 2, and the feeding mechanism 7 includes a column 72 fixedly mounted on the upper surface of the cutting frame 2, a driving sprocket 71 is connected to the keyway of the upper output shaft of the driving motor 13, and a driven sprocket 73 is rotatably connected to the top of the column 72, and a chain 74 is sleeved on the outer wall of the driving sprocket 71 and the driven sprocket 73, and a feeding plate 75 equidistantly distributed is installed on the outer wall of the chain 74;

[0080] The driving sprocket 71 is rotatably connected to the positioning frame 12 at its axis.

[0081] See also Figure 2 and Fig.11 : During the operation of the first embodiment, the driving motor 13 rotates counterclockwise and at the same time drives the driving sprocket 71 to rotate. During the rotation of the driving sprocket 71, the driven sprocket 73 is controlled to rotate synchronously at the top of the column 72 through the chain 74. During the rotation of the chain 74, multiple external feeding plates 75 are driven to move from the right side to the left side.

[0082] This embodiment: In the first embodiment, after the soybeans are cut, the conveying mechanism 4 is still in a clamping and conveying state for the soybeans, and is conveyed in the direction of the feeding mechanism 7. When the upper part of the soybeans is close to the chain 74, the transmission chain 74 will drive the feeding plate 75 to drive the soybeans on the chain 74 to be conveyed toward the outside of the ridge. Finally, all the soybeans are concentrated on the outside of the ridge. The conveying, cutting and feeding are integrated and linked. The soybeans can be fed after cutting, and the soybeans can be quickly concentrated on the side of the ridge, which is convenient for the subsequent combine harvester to carry out centralized harvesting.

[0083] Please refer to Figures 1 to 11 The working principle of the small harvester suitable for harvesting in different intercropping sowing modes provided by the present invention is as follows:

[0084] Step S1: Start the mobile motor 92 to control the power belt 93 to rotate. The power belt 93 transmits power to the central shaft 94. When the central shaft 94 rotates, it drives the mobile wheels 95 on both sides to move on the field, so that the frame 8 can be driven forward or backward. The user holds the handrail 10 to control the frame 8 to move forward, and the cutting frame 2 and the corn cutting mechanism 6 move forward together;

[0085] Step S2: The driving motor 13 controls the driving pulley 32 to rotate in the protective shell 31. When the driving pulley 32 rotates counterclockwise, the transmission driving belt 36 drives the driven pulley 33 to rotate counterclockwise, and the first gear 34 is bound to follow the driven pulley 33 to rotate counterclockwise. The counterclockwise rotating first gear 34 meshes with the transmission to control the second gear 35 to rotate clockwise. At this time, the driving pulley 32 and the second gear 35 control the two first pulleys 42 to rotate counterclockwise and clockwise, and the two first pulleys 42 drive the transmission belt 44 to transmit the transmission movement, and the transmission belt 44 During the transmission process, the conveying rod 45 on the outer wall will be driven to move relative to each other, so that the soybean stalks entering through the cutting frame 2 will be sent to the inside through the relatively moving conveying rod 45, and the first pulley 42 will synchronously drive the third pulley 52 at the bottom to rotate synchronously during the rotation process, and the transmission cutting belt 54 controls the rotation of the fourth pulley 53 at the same level, so that the rotation of the saw wheel 55 can be controlled, so that the transmission directions of the two saw wheels 55 and the two conveying belts 44 are consistent, and the soybeans sent in will be cut by the staggered rotating saw wheels 55 to the soybean stalk part;

[0086] The driving motor 13 rotates counterclockwise and drives the driving sprocket 71 to rotate. During the rotation of the driving sprocket 71, the driven sprocket 73 is controlled to rotate synchronously at the top of the column 72 through the chain 74. During the rotation of the chain 74, the multiple external feeding plates 75 are driven to transmit from the right to the left. After the soybean cutting is completed, the conveying mechanism 4 is still in a clamping and conveying state for the soybeans, and it is always conveyed in the direction of the feeding mechanism 7. When the upper part of the soybeans is close to the chain 74, the transmission chain 74 will drive the feeding plate 75 to drive the soybeans on the chain 74 to be conveyed toward the outside of the ridge.

[0087] Step S3: At this time, the corn on the corn ridge will enter the first distribution plate 65 and the second distribution plate 66 in turn, and enter the electric chain saw 67 through distribution. The rotating electric chain saw 67 can cut the corn stalks. At the same time, the corn will be stored inside the mounting frame 61 after cutting. As the mounting frame 61 continues to move forward, the cut corn will be exported through the gap between the second distribution plate 66 and the front plate 62. Therefore, the corn after cutting will be distributed behind the mounting frame 61 of the frame 8.

[0088] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
