DETAILED DESCRIPTION

[0040] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0041] Please refer to Figure 1-Figure 5 The present invention discloses a double-row corn stalk strip cleaning device, which consists of seven parts: Figure 1 , including a connecting frame 1, an adjusting component 2, a driving rod 3, a tire 4, a connecting block 5, a swinging component 6 and a driving component 7. The connecting frame 1 is connected to the driving rod 3 at the rear of the connecting frame, and a tire 4 is installed on the outer side of the bottom of the driving rod 3. The adjusting component 2 is installed on the connecting frame 1, and one end of the adjusting component 2 is inserted in the driving rod 3. The driving component 7 is installed on the connecting frame 1. The connecting blocks 5 are arranged in pairs and are installed on the front surface of the connecting frame 1. The top of the swinging component 6 is connected to the driving component 7, and the connecting block 5 is inserted in the swinging component 6.

[0042] When the present invention is in use, the pull ring 22 is first pulled to pull the insertion rod 21 out of the driving rod 3, so that the driving rod 3 is freed from the limit, and then the connecting frame 2 is moved along the driving rod 3. During the movement of the connecting frame 2, the driving shaft 71 is aligned with the main shaft of the agricultural machinery. The compression spring 23 is compressed during the process of pulling out the insertion rod 21. When the main shaft is aligned with the driving shaft 71 and connected together, the pull ring 22 is released, and the insertion rod 21 enters the driving rod 3 along the insertion hole under the action of the elastic force of the compression spring 23. When the insertion rod 21 is against the inner surface of the driving rod 3, the compression spring 23 is still in a compressed state, so that the insertion rod 21 is completely pressed into the driving rod 3, which can play a good limiting effect. After the main shaft is connected to the drive shaft 71, the entire device is connected to agricultural equipment such as a tractor through the connecting piece 14 and the mounting bracket 15. When the agricultural equipment is moving, the main shaft rotates to drive the drive shaft 71 to rotate, and the rotation of the drive shaft 71 will drive the cam 78 to rotate. When the cam 78 rotates, it will drive the push blocks 72 on the left and right sides to move, and drive the translation rod 74 to translate. During the movement, the translation rod 74 will move through the driving piece 76. The movement of the driving piece 76 can push the connecting rod 62 to swing. Before the connecting rod 62 swings, when the bottom end of the lifting rod 64 is against the ground, under the action of the ground support force, the lifting rod 64 moves up along the sleeve 65 and compresses the driving spring 66. When the connecting rod 62 swings, the lifting rod 64 swings, and the lifting rod 64 will move downward along the sleeve 65 under the action of the elastic force of the driving spring 66. The rod 64 can push the straw on the ground to both sides for cleaning. When the push block 72 is driven to move, one of the return springs 77 will be compressed, and the two push blocks 72 will be connected together by a connecting rod. At this time, the other return spring 77 will be stretched, and the action of the connecting rod will cause the two push blocks 72 to move at the same time, and cause the two connecting rods 62 to swing in the same direction to achieve the purpose of simultaneous cleaning and sweep away the straw on the land. When the cam 78 does not drive one of the push blocks 72 to move, the two return springs 77 will pull the two push blocks 72 back to their original positions, and reset the connecting rod 62 at the same time, so as to facilitate the next swinging operation. It can also ensure that the connecting rod 62 is always perpendicular to the ground when the equipment is not in use. This makes it easy to judge how far the connecting frame 2 needs to move on the driving rod 3, and can compress the compression spring 23 when the insertion rod 21 is against the ground.

[0043] In a specific embodiment, Figure 2The swing assembly 6 includes a round rod 61, a connecting rod 62, a round hole 63, a lifting rod 64, a sleeve 65, a driving spring 66, a connecting plate 67 and a mounting block 68. A mounting block 68 is installed on the side surface of the connecting rod 62. A round hole 63 is opened in the mounting block 68. The end of the connecting block 5 is inserted into the round hole 63. The round rod 61 is installed at the upper end of the connecting rod 62. One end of the driving assembly 7 is installed in the round rod 61. The sleeve 65 is arranged in pairs and installed at the bottom of the connecting rod 62. The lifting rod 64 is transmission-connected in the sleeve 65. The connecting plate 67 is installed between the two lifting rods 64. The driving spring 66 is installed on the connecting plate 67 and the sleeve 65. The round rod 61 is provided to connect the swing assembly 6 and the driving assembly 7 together to form a swing arm structure, and the round hole 63 is designed to insert the connecting block 5 therein, so that when the driving member 76 pushes the round rod 61, the connecting rod 62 flips along the connecting block 5, thereby realizing swinging. A clamping rod is installed at the upper end of the lifting rod 64 to prevent the lifting rod 64 from moving downward excessively and slipping out of the sleeve 65, and the connecting plate 67 is provided to connect the two lifting rods 64 together to produce the same lifting motion, so that the two lifting rods 64 can better contact with the straw and sweep out the straw. At the same time, the connecting plate 67 can also facilitate the installation of the drive spring 66.

[0044] In a specific embodiment, Figure 3 The driving assembly 7 includes a driving shaft 71, a pushing block 72, a connecting frame 73, a translation rod 74, a mounting hole 75, a driving member 76, a return spring 77 and a cam 78.

A pushing block 72 is installed on the surface of one end of the translation rod 74. A return spring 77 is installed between the pushing block 72 and the left and right plates of the connecting frame 73. The driving member 76 is installed on the other end surface of the translation rod 74, and a mounting hole 75 is opened on the other end of the driving member 76. The drive shaft 71 is used to drive the cam 78 to rotate, and the cam 78 will push the push block 72 to move and compress the return spring 77. By connecting the two push blocks 72 through a connecting rod, the two return springs 77 will be stretched and compressed respectively, which not only makes the two connecting rods 62 swing in the same direction, but also enables the connecting rod 62 to generate a greater return force when it is reset. The mounting hole 75 is sleeved on the outside of the round rod 61 and is used to connect the driving member 76 to the connecting rod 62.

[0045] In a specific embodiment, Figure 4The connecting frame 1 includes a rectangular block 11, a connecting plate 12, a mounting rod 13, a connecting piece 14, and a mounting frame 15.
