[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the fertilizer blocks are blocked in the feeding chute due to being too large in size, the accumulated fertilizer blocks can squeeze the shrinkage blocks in the feeding slope. While being squeezed, the shrinkage blocks can trigger the sensing end through the trigger rod. After being triggered, the sensing wire can energize the coil group. After the coil group is energized, an electromagnetic force is generated to attract the toggle rod to squeeze the starting piece. After being squeezed, the starting piece contacts the receiving end and the conveying end, so that the conveying end drives the starter to rotate.

After the push rod contracts, the rope-changing block at one end of its extended end squeezes the rope-changing button on the crusher. After being squeezed, the rope-changing button stops the rotation of the rope winding coil, while the shell of the crusher continues to rotate, causing the nylon rope on the rope winding coil to be thrown out and extended due to inertia. While the rope-changing block squeezes the rope-changing button, the inclined end of the activity groove squeezes the inclined end of the cutter. The squeezed cutter squeezes the downward pressure spring downward on the slide rod through the slider, causing its other end to extend. The extended cutter can cut off the redundant part of the extended nylon rope, thus performing the rope-changing work;

[0016] After the shrinkage block shrinks, the auxiliary wheel located in the auxiliary groove is exposed. After the fertilizer blocks are crushed, they fall, and when falling, they contact the auxiliary wheel, causing the auxiliary wheel to rotate due to inertia. After the auxiliary wheel rotates, its lobes drive the fertilizer blocks for auxiliary feeding. After the fertilizer blocks are fed in an auxiliary manner, they fall on the inclined feeding plate for discharging work.

The extended cutter 21 can cut off the redundant part of the extended nylon rope 1601, thus completing the rope changing work.

[0041] The specific operation process of this utility model is as follows: First, connect the device to the fertilizing port of the fertilizer applicator in advance, and then the discharge port of the device is communicated with the positioning fertilizing device. First of all, the fertilizer block enters the feeding chute. When the fertilizer block is blocked and squeezes the shrinkage block 5, the shrinkage block 5 shrinks into the shrinkage groove 301. The trigger rod on the back of one of the shrinkage blocks 5 contacts the sensing end 702 when the shrinkage block 5 shrinks. While contacting the sensing end 702, the sensing wire 1001 energizes the coil group 10. The holding coil and the attracting coil in the coil group 10 are energized to generate electromagnetic force and attract one end of the dial rod 11 to press the starting part 14. After being pressed, the other end of the starting part 14 contacts the receiving end 701 and the conveying end 703, and the conveying end 703 drives the starter 8 to operate. While the dial rod 11 presses the starting part 14, the other end thereof drives the push block 12 to slide to the right. While the push block 12 slides, the pinion 13 moves to the right, and its teeth mesh with the teeth of the driving gear 9, so that the driving gear 9 rotates. After the driving gear 9 rotates, its teeth mesh with the transmission gear 22 to rotate. After the transmission gear 22 rotates, it drives the input end of the pulley 20 to rotate. After the input end of the pulley 20 rotates, it drives the output end to rotate through belt transmission. Subsequently, the output end of the pulley 20 drives the shaft rod 23 to rotate. After the shaft rod 23 rotates, it drives the breaker 16 to rotate, so that the nylon rope 1601 on the breaker 16 breaks the blocked fertilizer block;

[0042] Secondly, the staff member grabs the handle 19 and pulls it, causing the handle 19 to drive the push rod 18 to contract. After the push rod 18 contracts, the rope-changing block 1801 at one end of its extended end presses the rope-changing button 1602 on the crusher 16. After being pressed, the rope-changing button 1602 stops the rotation of the rope-winding coil, while the housing of the crusher 16 continues to rotate, causing the nylon rope 1601 on the rope-winding coil to be thrown out and extended due to inertia. While the rope-changing block 1801 presses the rope-changing button 1602, the inclined end of the movable slot 1802 presses the inclined end of the cutter 21. The pressed cutter 21 presses the lower compression spring 25 downward on the sliding rod 24 through the slider 2101, causing the other end of the cutter 21 to extend. The extended cutter 21 can cut off the excess part of the extended nylon rope 1601, thus completing the rope-changing work. After the rope-changing work is completed, the handle 19 is pushed again to release the extrusion on the top of the cutter 21 inside the push rod 18. Subsequently, the cutter 21 contracts back towards the extension block 1701 through the resilience of the lower compression spring 25, thus releasing the cutting work on the nylon rope 1601;

[0043] In addition, after the contraction block 5 contracts, the auxiliary wheel 6 located in the auxiliary slot is exposed. After the fertilizer block is broken, it drops, and while dropping, it contacts the auxiliary wheel 6, causing the auxiliary wheel 6 to rotate due to inertia. After the auxiliary wheel 6 rotates, its lobes drive the fertilizer block for auxiliary feeding. After the auxiliary feeding of the fertilizer block, it falls on the inclined feeding plate 302 for discharging work;

[0044] Finally, after the fertilizer is normally fed, the contraction block 5 resets to its original position, causing the trigger rod to release the sensing connection to the sensing end 702, cutting off the power supply to the coil group 10 by the sensing wire 1001. Subsequently, the toggle lever 11 is reset to a vertical state by the resilience of the compression spring 15, causing the pinion 13 to be pulled back by the push block 12 to release the engagement with the driving gear 9, stopping the rotation of the driving gear 9. After the driving gear 9 stops rotating, the transmission gear 22 and the pulley 20 can stop driving the crusher 16, thus stopping the crushing work.
