[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0018] like Figures 1 to 3 As shown, the utility model preferably adopts a deep fertilizer spreading machine, and a fertilizer spreading device 2 is installed at the rear of the chassis 1.
[0019] like Figure 2 and Figure 3 As shown, the fertilizing device 1 includes a fertilizing bracket 20, on which a fertilizing mechanism 24 is installed, two lifting links 32, 33 are connected to the fertilizing bracket 20 and the chassis 1 at both ends, and the two lifting links 32, 33 and the chassis 1 and the fertilizing bracket 20 form a parallelogram mechanism; the two ends of the lifting cylinder 31 are connected to the fertilizing bracket 20 and the chassis 1 respectively. A pulley block 21 and a sliding frame 22 are installed on the chassis 1, and the sliding frame 22 is installed on the pulley block 21, and a fertilizer box 28 is installed on the sliding frame 21, and a delivery pipe 25 is connected between the fertilizer box 28 and the fertilizing mechanism 24; a pull rod 23 is installed on the fertilizing bracket 20, and the pull rod 23 is connected to the sliding frame 22; the lifting cylinder 31 drives the fertilizing bracket 20 to rise and fall, thereby driving the fertilizing box 28 to move forward and backward, and the delivery pipe 25 is always in a tensioned state. Avoid problems such as fertilizer blockage and poor fertilization caused by loose delivery pipes.
[0020] In order to tighten the delivery pipe 26 and avoid the formation of a downwardly sunken inflection point due to the sagging of the delivery pipe, which causes poor fertilization, a support rod 27 and a clamp 26 are installed on the fertilization bracket 20. The delivery pipe 26 is fixed to the support rod 27 by the clamp 26. The delivery pipe 26 forms an upwardly protruding inflection point at the position of the support rod 27, so that the delivery pipe 26 is tightened.
[0021] In order to ensure that the conveying pipe 26 always maintains a consistent tension, in a further technical solution, the sliding frame 22 includes a first cross bar 220, a second cross bar 221, a limit plate 222, and a crank arm 223. The first cross bar 220 and the second cross bar 221 are connected to each other, the limit plate 222 is located between the first cross bar 220 and the second cross bar 221, and the two ends of the crank arm 223 are respectively connected to the pull rod 23 and the second cross bar 221; an upper pulley 210 and a lower pulley 211 are installed on the pulley block 21, the first cross bar 220 is located between the upper pulley 210 and the lower pulley 211, and the second cross bar 221 is against the upper pulley 210.

[0022] When the lifting cylinder 31 drives the fertilizer support 20 to rise, the pull rod 23 rises, pushing the sliding frame 22 forward, driving the fertilizer box 28 forward, at this time the first spring 230 is compressed, the second spring 231 is extended, and the tension of the delivery pipe 26 remains unchanged. On the contrary, when the lifting cylinder 31 drives the fertilizer support 20 to rise and fall, the pull rod 23 rises, driving the sliding frame 22 to move backward, driving the fertilizer box 28 to move backward, at this time the first spring 230 is extended, the second spring 231 is compressed, and the tension of the delivery pipe 26 remains unchanged. Therefore, the lifting cylinder 31 drives the fertilizer support 20 to rise and fall, thereby driving the fertilizer box 28 to move forward and backward, the delivery pipe 25 is always in a tensioned state, and the delivery pipe 26 always maintains a consistent tension.
