Detailed ways

As shown in FIG. 1 , the normal distribution fertilization device described in the present invention includes a shovel handle 1 . The front side of the shovel handle 1 is vertically provided with a debris board 16 . The lower end of the chipping board 16 is provided with a subsoiling shovel 22 . A fertilizer discharge box 2 is installed on the rear side of the shovel handle 1, and a fertilizer discharge pipe 3 is installed on the top of the fertilizer discharge box 2. On the rear side wall of the fertilizer discharge box 2, an upper layer fertilizer discharge port 27, a middle layer fertilizer discharge port 13 and several lower layer fertilizer discharge ports 28 are successively set up from top to bottom. As shown in FIG. 3 , the upper fertilizer outlet 27 and the middle fertilizer outlet 13 are triangular, and the lower fertilizer outlet 28 is rectangular. The area of the upper layer fertilizer outlet 27 is smaller than the area of the middle layer fertilizer outlet 13 . A baffle plate 10 is provided above the lowermost fertilizer outlet 28 . the

When in use, the broken soil plate 16 and the subsoiler shovel 22 deeply loosen the soil, and at the same time, the fertilizer enters the fertilizer discharge box 2 from the fertilizer discharge pipe 3, and passes through the upper fertilizer discharge port 27, the middle fertilizer discharge port 13 and the lower layer respectively. The fertilizer outlet 28 is discharged into the soil in layers. The fertilizer discharge port 27 of the upper layer is less than the fertilizer discharge port 13 of the middle layer due to the small area, and the fertilizer discharge capacity of the fertilizer discharge port 13 of the middle layer is smaller than the lower layer fertilizer discharge port 28 of the middle part. The blocking, its fertilizer discharge amount is less than the lower layer fertilizer discharge port 28 fertilizer discharge amount in the middle, thereby, can realize the normal fertilization operation of upper and lower layers with less fertilization, and middle layer with more layers. the

In order to facilitate the replacement of different types of fertilizer discharge boxes 2, the fertilizer discharge box 2 and the shovel handle 1 should be easy to disassemble. The cross section of the fixing seat 5 is C-shaped. The rear side of the shovel handle 1 is provided with a second positioning plate 9 and a first positioning plate 4 . The fixing seat 5 cooperates with the second positioning plate 9 . The cooperation between the first positioning plate 4 and the second positioning plate 9 can make the fixing seat 5 and the shovel handle 1 firmly connected. As shown in Fig. 1, a guard plate 6 is provided at the bottom of the fixed seat 5, and a hinge seat 7 is arranged on the guard plate 6, and the fixed seat 5 is hinged with the fertilizer discharge box 2 through the hinge seat 7 and the shaft. The guard plate 6 can protect the fertilizer discharge box 2 and prevent the fertilizer discharge box 2 from being impacted by the front of the land during fertilization. The top of the fertilizer discharge box 2 is connected with the shovel handle 1 through a telescopic rod, and the two ends of the telescopic rod are hinged with the fertilizer discharge box 2 and the shovel handle 1 respectively. By adjusting the length of the telescopic rod, the angle of the fertilizer discharge box 2 relative to the shovel handle 1 can be adjusted, thereby adjusting the fertilization depth and fertilizer application amount of the fertilizer discharge box 2 according to the growth characteristics of different crops. The greater the inclination angle of the fertilizer discharge box 2 relative to the shovel handle 1, the smaller the fertilization amount of the lowermost lower fertilizer discharge port 28, and the deeper the fertilization depth of the upper layer fertilizer discharge port 27. the

According to the growth needs of crops, when the angle between the fertilizer discharge box 2 and the shovel handle 1 is larger, the amount of fertilizer applied to the lower fertilizer discharge port 28 should be smaller. In order to achieve the above purpose, as shown in Figure 2, the The bottom of the fertilizer box 2 is provided with two limiting plates 8, and the fertilizer retaining plate 14 is installed between the two limiting plates 8, and the fertilizer retaining plate 14 can move up and down along the limiting plate 8.

Several fat retaining plate through holes 29 are offered on the fat retaining plate 14, and the fertilizer retaining plate through holes 29 correspond to the fertilizer outlet 28 of the lower floor one by one. When the fertilizer discharge box 2 is in position as shown in FIG. 1 , the through hole 29 of the fertilizer retaining plate communicates completely with the fertilizer discharge port 28 of the lower layer. As shown in FIG. 6 , the telescopic rod has a rod body 32 , and the upper end of the rod body 32 is hinged with the shovel handle 1 . An inner hole 26 is provided in the rod body 32, and a lead screw 25 is installed in the inner hole 26, and the lead screw 25 can move along the inner hole 26 in a straight line. An annular groove 30 is defined on the outer periphery of the lower part of the rod body 32 . A nut 24 is installed on the bottom periphery of the fertilizer discharge pipe 3 . A positioning pin 31 is installed on the nut 24 , and the positioning pin 31 cooperates with the annular groove 30 to ensure that the nut 24 can only rotate relative to the rod body 32 . Leading screw 25 is threadedly connected with nut 24; A wire wheel 23 is installed on the outer periphery of the nut 24 , and the wire wheel 23 is fixedly connected with the nut 24 through a positioning pin 31 . The outer periphery of the wire wheel 23 is wound with the stay cord 12 , and the stay cord 12 is connected with the draw bar 15 . When it is necessary to increase the angle between the fertilizer discharge box 2 and the shovel handle 1, the screw nut 24 is rotated to push the lead screw 25 outwards, and at the same time, the nut 24 drives the wire pulley 23 to rotate synchronously, and the wire pulley 23 tightens the stay rope 12, pulling Rope 12 pulls pull bar 15 and moves up along limit plate 8, makes the through hole 29 of fertilizer retaining plate staggered with lower floor fertilizer outlet 28, thereby further reduces the fertilizer output of lower floor fertilizer outlet 28. the

As shown in FIG. 7 , a protrusion 20 is provided on the outside of the pull rod 15 . A chute 21 is provided on the limiting plate 8 , and the chute 21 cooperates with the protrusion 20 .
