Description

Technical Field

[0001] The invention relates to the technical field of spreaders, in particular to a left-right throwing mechanism of a spreader. Background Art

[0002] In a broad sense, a spreader is a device that can spread materials onto the ground or in the air through its movement; in a narrow sense, it mainly refers to equipment used to spread snow-melting agents, deicing agents and other granular or powdered materials. In terms of snow and ice removal functions, it can be divided into snow-melting agent spreaders and liquid spreaders. In terms of power and drive mode, it can be divided into engine spreaders and hydraulically driven spreaders.

[0003] The existing spreader has a fixed spreading range and cannot drive the spreading device to move left and right, so that the spreading range is very limited, making it impossible for the spreader to improve the spreading efficiency, thereby reducing the practicality of the spreader.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a left and right spreading mechanism of a spreader, including a spreader body 1. A connecting frame 9 is fixedly installed at the bottom of the spreader body 1. A support frame 4 is rotatably supported on the connecting frame 9. A transmission assembly 6 is arranged on the support frame 4. The transmission assembly 6 includes a fixed shaft 61, a gear 62, a motor 63, a rotating shaft 64 and a half gear 65. The motor 63 is fixed on the support frame 4. A rotating shaft 64 is drivingly connected to the motor 63. The rotating shaft 64 penetrates the support frame 4 and the rotating shaft 64 rotates on the support frame 4. The rotating shaft 64 is fixed to the half gear 65. The fixed shaft 61 is fixed on the connecting frame 9. The gear 62 is on the fixed shaft 61. The gear 62 meshes with the half gear 64. By the operation of the motor 63, the rotating shaft 64 and the half gear 65 can be driven to rotate, so that the half gear 65 can rotate on the gear 62, so that the support frame 4 can be driven to rotate. A spreading assembly 3 is fixedly installed on the support frame 4. The spreading assembly 3 is communicated with the spreader body 1 through a telescopic pipe 2. The rotation of the support frame 4 can drive the spreading assembly 3 to rotate. Due to the telescopic action of the telescopic pipe 2, the spreading assembly 3 and the spreader body 1 can always be kept connected.

[0024] In order to limit and fix the throwing component 3 actively, a limiting component 7 is provided on the spreader body 1. The limiting component 7 includes an L-shaped fixing plate 71, a first elastic element 72, a limiting plate 73 and a limiting gear 74. The L-shaped fixing plate 71 is fixed on the spreader body 1. The spreader body 1 is fixed to the limiting plate 73 through the first elastic element 72. The limiting gear 74 is fixedly installed on the support frame 4. The limiting plate 73 can limit the limiting gear 74, so that the support frame 4 can be fixed, and the throwing component 3 can be fixed. When the spreader body 1 moves through a transportation tool, the throwing component 3 will not rotate randomly, improving the safety of the throwing component 3. An arc-shaped chute 10 is fixedly installed on the connecting frame 9. The third elastic element 11 is fixed inside the arc-shaped chute 10. The arc-shaped chute 10 is fixed to the slider 5 through the third elastic element 11. The slider 5 moves inside the arc-shaped chute 10. The slider 10 is fixed to the support frame 4. Through the elastic force of the third elastic element 11 and the action of the half gear 65, the throwing component 3 can be driven to rotate reciprocally, so that the throwing range of the throwing component 3 can be increased, and the throwing efficiency of the throwing component 3 is improved.

[0025] In this embodiment, a control component 8 is provided on the L-shaped fixing plate 71. The control component 8 includes a control rod 81, a second elastic element 82, a limiting block 83 and a pull rod 84. The control rod 81 is fixedly connected to the limiting plate 73. The control rod 81 penetrates the L-shaped fixing plate 71 and the control rod 81 slides on the L-shaped fixing plate 71. The limiting plate 73 can be controlled through the limiting block 83. The second elastic element 82 is fixed on the L-shaped fixing plate 71. The L-shaped fixing plate 7 is fixed to the limiting block 83 through the second elastic element 82. The pull rod 84 is fixed to the limiting block 82. The left side of the limiting plate 73 and the right side of the limiting block 83 are both beveled, so that the limiting plate 73 can move to the left. However, when the limiting plate 73 moves to the right, the limiting block 83 can limit the limiting plate 73. The pull rod 84 penetrates the L-shaped fixing plate 71 and the pull rod 84 moves up and down on the L-shaped fixing plate 71. The limiting plate 73 can be limited through the limiting block 73, so that when the limiting gear 74 rotates, the limiting plate 73 will not limit the limiting gear 74. Only by pulling down the pull rod 84 can the limit of the limiting block 83 on the limiting plate 73 be released, making the limiting component 7 more convenient to use.

[0026] When it is necessary to rotate the spreading assembly 3 during operation (or use), first push the control lever 81 to the left. The leftward movement of the control lever 81 can drive the limit plate 73 to move to the left. The inclined surface of the limit plate 73 will push the limit block 83 downward as the limit plate 73 moves to the left, so that the limit plate 73 moves to the right of the limit block 83, enabling the limit block 83 to limit the limit plate 73. As the limit plate 73 moves to the left, the limit plate 73 can no longer limit the limit gear 74. Then, turn on the motor 73. The operation of the motor 73 can drive the rotating shaft 64 and the half gear 65 to rotate. The rotation of the half gear 65 causes the half gear 65 to rotate on the gear 62. The rotation of the half gear 62 can drive the support frame 4 and the spreading assembly 3 to rotate. When the half gear 65 disengages from the gear 62, under the elastic force of the third elastic element 11, it can push the support frame 4 to rotate in the opposite direction, enabling the support frame 4 to rotate reciprocally, thereby increasing the spreading range of the spreading assembly 3.
