A fertilizer box 3 is provided at the upper end of the frame 1, a granular fertilizer box 4 is provided at the front end of the fertilizer box 3, a fertilizer discharge port 31 is provided at the front end of the fertilizer box 3, a transmission belt for transporting fertilizer discharged from the fertilizer discharge port 31 is provided in the fertilizer box 3, a fertilizer guide pipe 44 is provided in the granular fertilizer box 4, a fertilizer discharge auger 41 capable of conveying granular fertilizer discharged from the fertilizer guide pipe 44 is provided in the granular fertilizer box 4, and a transverse fertilizer discharger 5 capable of conveying mixed fertilizer to one side is provided at the lower end of the fertilizer discharge port 31 and the fertilizer guide pipe 44. A material guide trough 51 is provided on one side of the transverse fertilizer discharger 5, and a fertilizer knife 6 is provided on the side of the frame 1, and the fertilizer knife 6 and the material guide trough 51 are located on the same side and the fertilizer knife 6 is located at the rear side of the material guide trough 51. During the movement of the fertilizer spreader, the traction device is fixed to the traction frame 2 to drive the movement of the fertilizer spreader. During the movement of the fertilizer spreader, the fertilizer in the fertilizer box 3 is pushed into the horizontal fertilizer discharger 5 through the fertilizer discharge port 31, and the granular fertilizer in the granular fertilizer box 4 falls into the horizontal fertilizer discharger 5 at the same time, and then falls on one side of the frame 1 through the guide trough 51. As the traction-type deep loosening and mixing fertilizer spreader passes by, the fertilizer knife 6 rotates to turn over the soil with fertilizer, mix the fertilizer and soil, and realize the fertilization process.
[0022] like Figure 1-3 As shown, the traction frame 2 is a square tube hinged to the frame 1, and the square tube includes a left square tube and a right square tube, which are symmetrically arranged, and the distance between the left square tube and the right square tube gradually decreases from the back to the front. A traction rod is provided at the front end of the square tube, and the front end is connected to the traction frame 2 through the traction rod to drive the movement of the mixing fertilizer spreader. Adjustment rods are hinged on the left and right square tubes. The height of the square tube can be adjusted by adjusting the rods, and the angle between the traction frame 2 and the frame 1 can be adjusted at the same time. The traction frame 2 is adjusted according to different road conditions to ensure the stability of the traction process.
[0023] like Figure 1-4As shown, the fertilizer box 3 is a box-shaped box with an upper opening, and the rear end surface of the fertilizer box 3 is an inclined surface. The bottom end of the fertilizer box 3 is provided with a transmission belt that can move the fertilizer forward. The lower end surface of the front end plate of the fertilizer box 3 is higher than the upper end surface of the transmission belt. There is a fertilizer discharge port 31 between the front end plate of the fertilizer box 3 and the transmission belt of the fertilizer box 3. When the transmission belt drives the fertilizer in the fertilizer box 3 to move forward, the upper fertilizer is blocked by the front end plate of the fertilizer box 3, and the lower fertilizer leaks out of the fertilizer discharge port 31. The transmission belt includes a driving shaft located at the front side of the fertilizer box 3, and a driven shaft is provided at the rear end of the fertilizer box 3. The driving shaft and the driven shaft are meshed with a transmission belt outside, which drives the transmission belt to move, and then the fertilizer on the transmission belt slides from the fertilizer discharge port 31, and the fertilizer after sliding falls into the horizontal fertilizer discharger 5. A fertilizer control adjustment plate 34 that can adjust the gap height is installed on the front end plate of the fertilizer box 3. The width of the fertilizer control adjustment plate 34 is consistent with the width of the front end plate of the fertilizer box 3. The left and right ends of the fertilizer control adjustment plate 34 are provided with slideways, and the left and right ends of the fertilizer control adjustment plate 34 are both extended into the slideways and can move up and down along the slideways. A screw rod is installed on the upper end of the fertilizer control adjustment plate 34. By moving the screw rod, the height of the fertilizer control adjustment plate 34 is adjusted, and then the size of the fertilizer discharge port 31 is adjusted. The larger the fertilizer discharge port 31, the more fertilizer falls at the same time, and the smaller the fertilizer discharge port 31, the less fertilizer falls at the same time, and then the fertilizer box 3 is adjusted. When planting different crops, the height of the fertilizer control adjustment plate 34 is adjusted, and then the amount of fertilizer discharged at the same time is adjusted, and then the mixing ratio with the granular fertilizer is changed to achieve a better fertilization effect, improve the efficiency of fertilization and the quality of crops. A stirring shaft 32 is provided in the fertilizer box 3. The stirring shaft 32 is located at the rear side of the fertilizer discharge port 31. The stirring shaft 32 and the driving shaft of the transmission belt of the fertilizer box 3 are driven by a chain. The stirring shaft 32 is provided with staggered stirring blades 33. The stirring blades 33 are staggered and the adjacent stirring blades 33 are set at different angles. The fertilizer blocked by the fertilization control adjustment plate 34 and the front end plate is broken up to avoid the fertilizer being difficult to fall after being squeezed, which is convenient for subsequent mixing. The broken fertilizer is easier to fall from the fertilizer discharge port 31 and falls more evenly, which improves the transportation efficiency. At the same time, the stirring shaft 32 and the driving shaft of the transmission belt are driven by a chain, and there is no need to apply power to the stirring shaft 32 separately, which improves the efficiency.
[0024] like Figure 1 , 2As shown in Figures 3, 5, a granular fertilizer box 4 for storing granular fertilizer is provided at the front end of the fertilizer box 3, a fertilizer guide pipe 44 is provided at the lower end of the left end face of the granular fertilizer box 4, and a fertilizer discharge auger 41 is provided at the bottom of the inner side of the granular fertilizer box 4 to rotate and drive the granular fertilizer to discharge from the fertilizer guide pipe 44. A granular fertilizer box cover that can be opened and closed is hinged at the upper end of the granular fertilizer box 4, and the granular fertilizer box cover prevents the granular fertilizer from leaking during walking. The fertilizer discharge auger 41 includes a rotating horizontal axis, and an auger blade 43 is spirally arranged on the horizontal axis. The fertilizer near the fertilizer discharge auger 41 is moved along the blade to one end of the granular fertilizer box 4 through the rotation of the fertilizer discharge auger 41. In order to ensure that all fertilizers can enter the fertilizer auger 41, the lower part of the granular fertilizer box 4 is inverted cone-shaped, and the lower fertilizer auger 41 between the front side plate and the rear side plate of the granular fertilizer box 4 is tilted, and the granular fertilizer slides down to the fertilizer auger 41 along the tilted front side plate and the rear side plate, so as to avoid the accumulation of granular fertilizer in the granular fertilizer box 4 and improve the conveying efficiency of the fertilizer auger 41. The number of revolutions of the fertilizer auger 41 is related to the amount of granular fertilizer falling, so by controlling the rotation speed of the fertilizer auger, the proportion of granular fertilizer in the mixed fertilizer can be adjusted to achieve a better fertilization effect, improve the efficiency of fertilization and the quality of crops. The left end of the fertilizer auger 41 is located in the fertilizer guide pipe 44, and the left end of the fertilizer guide pipe 44 is provided with an opening, and the lower end of the opening is hinged with a granular fertilizer guide groove, and the granular fertilizer slides down through the granular fertilizer guide groove 51. Because the fertilizer box 3 is arranged above the horizontal fertilizer discharger 5, the granular fertilizer guide groove 51 is also located above the horizontal fertilizer discharger 5. The granular fertilizer falls along the granular fertilizer guide groove under the influence of gravity and falls into the horizontal fertilizer discharger 5. The granular fertilizer and the fertilizer are mixed according to a certain proportion and then fertilized.
[0025] like Figure 1-4As shown, the transverse fertilizer discharging device 5 includes a transverse conveyor belt arranged in the left and right directions, and the width of the transverse belt in the left and right directions is greater than the width of the fertilizer box 3, so as to ensure that all the fertilizer can fall into the transverse fertilizer discharging device 5. A front guard plate 53 is provided at the front end of the transverse transmission belt 52, and a rear guard plate 54 is provided at the rear end of the transverse transmission belt 52, and both are arranged obliquely. The distance between the front guard plate 53 and the rear guard plate 54 gradually increases from bottom to top, and the upper end is open. The distance between the upper end openings of the front and rear baffles is greater than the distance between the front and rear of the transverse fertilizer discharging device 5, so as to ensure that all the fertilizer falling from the upper end falls into the conveyor belt of the transverse fertilizer discharging device 5. In this embodiment, a fertilizer guide trough is provided at the left end of the transverse fertilizer discharging device 5, and the upper part of the fertilizer guide trough is hinged with the frame 1. The upper end of the fertilizer guide trough is provided with a feed inlet and the lower end is provided with a discharge outlet. The distance between the left and right side walls of the fertilizer guide trough gradually decreases from top to bottom, and the fertilizer slides downward along the left and right side walls by gravity until it falls from the discharge outlet. A fertilizer guide trough adjustment rod capable of changing the angle between the fertilizer guide trough and the frame 1 is provided between the fertilizer guide trough and the frame 1, and the discharge speed and discharge position of the discharge port of the fertilizer guide trough are adjusted by the fertilizer guide trough adjustment rod. In the present embodiment, the fertilizer guide trough adjustment rod is a cylinder. Because in the present embodiment, the fertilizer guide trough is on the left side of the horizontal fertilizer discharger 5, the fertilizer guide trough adjustment rod is located on the right side of the right side wall of the fertilizer guide trough, and the two ends of the fertilizer guide trough adjustment rod are respectively hinged to the frame 1 and the right side wall of the fertilizer guide trough. In the present embodiment, the right end face of the right side wall of the fertilizer guide trough is provided with a hinged piece for hinged connection with the fertilizer guide trough adjustment rod, and the hinged piece is located on the lower side of the right end face of the right side wall. The length is adjusted by the fertilizer guide trough adjustment rod, and then the angle between the fertilizer guide trough and the frame 1 is adjusted. When the fertilizer guide trough adjustment rod is extended, the angle between the fertilizer guide trough and the frame 1 becomes larger, the distance between the discharge port of the fertilizer guide trough and the frame 1 increases, and the vertical opening of the discharge port becomes smaller, then the fertilizer that can fall in the same time period is reduced, thereby adjusting the amount of fertilizer applied during walking. When the fertilizer guide trough adjustment rod is shortened, the angle between the fertilizer guide trough and the frame 1 becomes smaller, the distance between the discharge port of the fertilizer guide trough and the frame 1 is shortened, and the vertical opening of the discharge port becomes larger, then the fertilizer that can fall in the same time period is increased, thereby increasing the amount of fertilizer applied during walking. The amount of fertilizer applied can be adjusted by adjusting the fertilizer guide trough, and then adjusted according to different planting varieties, thereby increasing applicability.
[0026] like Figure 1 , 2As shown in , 3, 6, and 7, a fertilizer knife 6 capable of mixing soil and fertilizer is provided next to the machine tool. A transmission box bracket square tube 61 is hinged on one side of the frame 1, and the fertilizer knife 6 is installed on the rear side of the transmission box bracket square tube 61. An adjusting device 65 capable of adjusting the hinge angle between the transmission box bracket square tube 61 and the frame 1 is installed on the transmission box bracket square tube 61. In this embodiment, the adjusting device 65 is an oil cylinder. The adjusting device 65 adjusts the angle of the transmission box bracket square tube 61, and then adjusts the depth of the fertilizer knife 6, and can adjust the depth of the soil for stirring and loosening the soil, and then adjusts it according to needs, so as to adapt to different crop planting and improve the applicability of the device. A fertilizer knife 6 capable of mixing fertilizer and soil is installed at the rear end of the transmission box bracket square tube 61, and a fertilizer knife guard plate 66 is covered on the fertilizer knife 6, and a rear support plate is hinged on the rear side of the fertilizer knife guard plate 66. The upper end surface of the fertilizer knife shield plate 66 is arc-shaped, and the fertilizer knife shield plate 66 covers the upper half of the fertilizer knife 6. The fertilizer knife 6 includes two parallel fertilizer knife mounting discs 62. The fertilizer knife mounting disc 62 is a circular disc, and the axis of the fertilizer knife mounting disc 62 is in the left and right direction. The right end of the fertilizer knife mounting disc 62 is connected with a fertilizer knife drive shaft, and the fertilizer knife drive shaft drives the fertilizer knife mounting disc 62 to rotate along the axis. A plurality of fertilizer knife 6 mounting pipes are arranged between the two fertilizer knife mounting discs 62, and the plurality of fertilizer knife 6 mounting pipes have the same length and are parallel to each other. The fertilizer knife 6 mounting pipes fix the distance between the two fertilizer knife mounting discs 62, so that the distance between the two fertilizer knife mounting discs 62 is parallel to each other. The left end surfaces of the two fertilizer knife mounting discs 62 are both installed with a plurality of left fertilizer blades 63, and the right end surfaces of the two fertilizer knife mounting discs 62 are both installed with a plurality of right fertilizer blades 64.
