[0002] The fertilizer applicator is a machine for applying fertilizer. Most of the existing fertilizer applicators are composed of a fertilizer tank, a fertilizer distributor and the like, and some have a fertilizer conveying device, a furrowing device and a covering device (a roller type soil covering and rolling device). Then, the soil covering device basically adopts a roller to complete the soil covering, and the soil covering is performed by relying on the self weight of the roller. However, due to the structure of the roller, it is difficult to achieve uniform soil covering during the soil covering process. SUMMARY

[0011] The utility model discloses a rack 2, the fertilizer box 3 of installation on the rack 2, share plough 108, see Figure 1 , the utility model installs the left and right two cage fertilization mechanism on the whole rack, installs the soil breaking, soil loosening and other mechanism in the front of the rack, installs the ploughing and soil breaking mechanism in turn below the rear side of the rack 2 after passing through the soil breaking, soil loosening and other procedures, the utility model is just redesigned the ploughing and soil breaking mechanism, so as to increase the effect of fertilization, soil covering.

[0012] Ploughing and soil breaking mechanism: see Figure 2 , two pieces of clamping crank 101 are fixedly installed below the rack 2, and the clamping crank 101 is a connecting piece, is used for suspending plough and soil covering mechanism, in order to play the suspension and clamping firm installation, adopt two pieces, and two pieces of clamping crank 101 are designed into an irregular shape of the form, and the front end is used for fixed installation with the rack 2, and the rear end protruding portion is used for installing soil breaking mechanism, and the ploughing mechanism is installed below. Figure 2

[0013] Ploughing mechanism (also deep loosening mechanism): share plough installation beam 110 is fixedly installed between two pieces of clamping crank 101, that is, two pieces of clamping crank 101 hold share plough installation beam 110, and are fixed with bolt, Figure 2 And Figure 4 It can be seen that the front of this beam also has a blade, and the blade is on the same blade line with the blade of share plough 108, and the bottom end of share plough 108 is designed to be the same as the top end structure of share plough 108, also simultaneously having a blade, so that, after installing share plough 108, from the left side (as a reference) looks, the blade line of the whole share plough installation beam 110 and the blade of the front of share plough 108 is from top to bottom. Figure 4

[0014] Share plough installation beam 110 lower end both sides install the soil loosening wing shovel 107, when deep loosening soil, since share plough installation beam 110 and share plough 108 are only from the front to the soil deep loosening cut, but the soil divided to both sides possibly some hard soil or soil block etc., at this moment, in order to cooperate with the soil block etc. shovel broken, therefore, increase soil loosening wing shovel 107, can greatly reduce the formation of excessive soil block.

[0015] ​​The lower end rear side of the share plow mounting beam 110 is provided with a fertilizer pipe 109, and the upper end inlet of the fertilizer pipe 109 is communicated with the fertilizer discharge port 5 below the fertilizer box 3 through a fertilizer hose. The fertilizer pipe 109 is located at the rear side of the share plow mounting beam 110, and after the front share plow 108 is used to turn over the soil, the fertilizer pipe 109 needs to send the fertilizer into the ditch. In order to send the fertilizer into the slightly deep part of the ditch, the lower end of the fertilizer pipe 109 needs to be deep, and the depth is similar to the root of the share plow 108. Therefore, the fertilizer pipe 109 is made of a relatively hard material, and the upper end of the fertilizer pipe 109 is communicated with the fertilizer discharge port 5 below the fertilizer box 3 through a soft fertilizer pipe. The fertilizer in the fertilizer box is sent into the soil through the fertilizer discharge port 5, the fertilizer hose and the fertilizer pipe 109.

[0016] The soil covering and crushing mechanism: two soil covering hangers 103 are respectively installed on the outer sides of the protruding parts of the two clamping cranks 101 through connecting shafts 102. The soil covering hanger 103 is a connecting bracket for connecting the share plow mounting beam 110 and a mechanism for installing soil covering rollers. The utility model applies two soil covering hangers 103, as shown in Figure 3 The two soil covering hangers 103 are divided into upper and lower two sections. The upper section is a narrow gap section 10301, and the lower section is a wide gap section 10302. The bottom ends of the two narrow gap sections 10301 are tightly installed through narrow section screws 104. The lower ends of the wide gap sections 10302 are provided with soil covering roller shaft holes 10303. The two ends of the soil covering shaft 106 are respectively installed in the form of shafts on the soil covering roller shaft holes 10303 on the two wide gap sections 10302. The soil covering roller mounting plates 112 are fixedly installed at the positions close to the inner sides of the two wide gap sections 10302 at the two ends of the soil covering shaft 106. The two ends of the spiral soil covering roller 105 are respectively fixed on the two soil covering roller mounting plates 112.

[0017] The narrow gap section 10301 is a connecting suspension part. The upper end of the narrow gap section 10301 is provided with a shaft hole 10305, and the lower end is provided with a positioning thread hole 10304. The shaft hole 10305 is installed on the clamping crank 101 through the connecting shaft 102. The lower end positioning thread hole 10304 fixes the two soil covering hangers 103 through bolts (narrow section screws 104).

[0018] The wide gap section 10302 is to bend the two soil covering hangers 103 outward to form a larger clamping space for installing the spiral soil covering roller 105 and its bracket, as shown in Figure 2 As can be seen from the figure, the spiral soil covering roller 105 is similar to a horizontally placed spring and can roll around the soil covering shaft 106. The soil covering shaft 106 is inserted into the soil covering roller shaft hole 10303 in the form of a shaft, that is, the soil covering shaft 106 can roll in the soil covering roller shaft hole 10303. The structure of the spiral soil covering roller 105 can press the soil through its own weight and can crush and cover the soil through the gap. Through practice, the effect of crushing and covering the soil is improved compared with the existing roller type soil covering roller, and the spiral type can uniformly cover the soil.

[0019] Two end protruding limiting fixed pins 111 are installed at the lower end of the two protruding parts behind the clamping bracket 101, see Figure 2 As can be seen, the two ends of the limiting fixed pin 111 are slightly long, and the lower part of the two soil covering hangers 103 is placed on the limiting fixed pin 111, which is used to limit the distance between the spiral soil covering roller 105 and its hanger and the share plow 108 and its hanger.

[0020] The lower end of the tension spring 113 is hung on the narrow section screw 104, and the upper end is hung on the limiting fixed pin 111. The self weight of the conventional roller type soil covering roller is relatively heavy, and the spiral soil covering roller is used in the utility model, so the self weight is slightly lighter than that of the roller type soil covering roller, which may not achieve the ideal effect, at this time, a spring tension is set to increase the downward pressing force, see Figure 4 When the share plow 108 works deeply into the soil, the spiral soil covering roller 105 and its hanger will spread outward with the connecting shaft 102 as the axis, so that the tension spring 113 will be stretched under stress, so that the spiral soil covering roller 105 contacts the ground under the double action of the self weight plus the elastic force of the tension spring 113 to cover the soil.
