[0046] Combine the following Figures 1 to 8 A liquid manure deep spreading machine provided in an embodiment of the utility model is described.

[0047] The present embodiment provides a liquid manure deep spreading machine, comprising: a frame 1, a fertilizer supply device, a plurality of trenching and fertilizing shovels 2 and a traveling mechanism.

[0048] Among them, the fertilizer supply device is arranged on the frame 1, and each trenching and fertilizing shovel 2 is arranged on the frame 1 with adjustable height. The trenching and fertilizing shovel 2 includes a fertilizer applicator 21, and the top of the fertilizer applicator 21 is connected to the fertilizer supply device through a connecting pipe 5. The connecting pipe 5 can be a hose, and the bottom of the fertilizer applicator 21 is provided with a main fertilizer discharge port 211; the walking mechanism includes walking wheels 3, and multiple walking wheels 3 are respectively arranged on both sides of the frame 1. The walking wheels 3 are in contact with the soil surface to keep the main fertilizer discharge port 211 of the fertilizer applicator 21 at a consistent depth in the soil during the movement of the frame 1.

[0049] It can be known from the above scheme that when the utility model is working, the height of the trenching and fertilizing shovel 2 is adjusted to control the depth of the trench, so that liquid manure can be delivered to the soil at different depths through the main fertilizer discharge port 211 of the fertilizer applicator 21 to solve the problem that deep soil fertilization operations cannot be completed. The walking wheels 3 on both sides of the frame 1 are in contact with the soil surface to maintain the stability of the frame 1 and reduce the travel resistance. It can also ensure that the main fertilizer discharge port 211 of the fertilizer applicator 21 enters the soil at a consistent depth during the movement of the frame 1, thereby improving the fertilization effect.

[0050] like Figure 1 As shown, the above-mentioned trenching and fertilizing shovels 2 are provided in plurality to improve the fertilization efficiency. The plurality of trenching and fertilizing shovels 2 can be arranged in multiple rows on the frame 1, for example, in two front and rear rows on the frame 1, and each trenching and fertilizing shovel 2 is connected to the fertilizer supply device through a connecting pipe 5.

[0051] like Figure 2 and Figure 3 As shown, the trenching and fertilizing shovel 2 also includes a trench opener 22, which is connected to the frame 1 through a height adjustment structure. The fertilizer applicator 21 is connected to the trench opener 22. The fertilizer applicator 21 is provided with a cavity, and the connecting pipe 5 and the main fertilizer discharge port 211 are both connected to the cavity. A plurality of branch fertilizer discharge ports 212 connected to the cavity are provided on the outer side of the fertilizer applicator 21 along the height direction.

[0052] In this way, the furrow opener 22 is connected to the frame 1 through the height adjustment structure, so that the height of the furrow opener 22 can be adjusted, so that the depth of the furrow opener 22 entering the soil can be adjusted, so that the liquid manure can enter the deep soil and complete the deep application of manure; through the multiple fertilizer outlets 212 arranged along the height direction on the outer side of the fertilizer applicator 21, layered fertilization of the soil can be achieved, the fertilization effect and the utilization rate of liquid manure can be improved, and the fertilizer can be applied in different soil layers, so that nutrients can be more effectively supplied to crops for absorption and utilization, thereby ensuring the growth of crops and helping to increase yields.

[0053] In some embodiments, the height adjustment structure includes: a plurality of first connection holes 221 and a first connection member, wherein the plurality of first connection holes 221 are arranged on the furrow opener 22, and the plurality of first connection holes 221 are arranged at intervals along the height direction; the first connection member is arranged on the frame 1, and the first connection member is provided with a first through hole, and the first through hole is connected to the first connection hole 221 by a fastener such as a bolt; Figure 2 As shown, the upper part of the furrow opener 22 is provided with a plurality of first connecting holes 221 along the height direction, and the first connecting member is a connecting sleeve or a pair of clamping plates. During installation, the top of the furrow opener 22 is inserted into the connecting sleeve or the gap between the pair of clamping plates, and according to the required furrowing depth, the first connecting hole 221 of appropriate height is selected and connected with the first through hole through bolts, so as to fix the furrow opener 22 on the frame 1.

[0054] In this way, by selecting the first connecting holes 221 of different heights and connecting them to the first through holes on the first connecting member, the connection between the furrow opener 22 and the frame 1 is achieved, and by replacing the first connecting holes 221 of different heights, the installation height of the furrow opener 22 can be adjusted, thereby controlling the depth of soil furrowing to achieve deep application of manure in deep soil.

[0055] Preferably, the furrow opener 22 is provided with a weight-reducing hole 222, which can reduce the weight of the furrowing and fertilizing shovel 2 while ensuring the structural strength of the furrow opener 22, thereby reducing the operating resistance during the furrowing process.

[0056] Reference Figure 1 and Figure 4 In this embodiment, the fertilizer supply device includes a distributor 4 and a fertilizer supply pipe 6. The distributor 4 is arranged on the frame 1, including a fertilizer inlet 41 and a plurality of fertilizer outlets 42.

The plurality of diverter plates 44 are evenly distributed at the bottom of the cylinder 43 along the circumferential direction. The space between two adjacent diverter plates 44 forms a diverter groove, which corresponds to the fertilizer outlet 42. The end cover 45 is detachably connected to the top of the cylinder 43, which can be bolted or clamped. The fertilizer inlet 41 is arranged at the center of the end cover 45.

[0060] With such an arrangement, the liquid manure entering the cylinder 43 can be evenly distributed to each fertilizer outlet 42 through the arrangement of the diverter plate 44, ensuring that the amount of liquid manure entering each fertilizer applicator 21 is consistent, avoiding the problem of inconsistent fertilizer amounts in the soil corresponding to each fertilizer applicator 21, and improving the fertilization effect.

[0061] Furthermore, the distributor 4 further comprises: a blade 46 and a motor 47, such as Figure 5 and Figure 6 As shown, a blade 46 is rotatably disposed at the bottom center of the cylinder 43, a plurality of diverter plates 44 are disposed around the blade 46, a motor 47 is disposed at the outer bottom end of the cylinder 43, and an output shaft of the motor 47 is connected to the blade 46. The rotation of the blade 46 can break solids in the fertilizer to prevent the fertilizer outlet 42 from being blocked.

[0062] Optionally, a circle of connecting ear plates is provided on the outer side of the cylinder 43 , threaded holes are provided on the ear plates, and the ear plates are connected to the frame 1 by bolts, so that the cylinder 43 is fixed to the top of the frame 1 .

[0063] Reference Figure 7 In this embodiment, the walking mechanism also includes a bracket 8 and a shock absorber 9, the shock absorber 9 is a spring shock absorber, the bracket 8 is connected to the frame 1, the shock absorber 9 is arranged on the bracket 8, and the bottom of the bracket 8 is connected to the walking wheel 3.

[0064] In this way, the spring shock absorber is arranged to play a role of buffering and absorbing vibration. When the walking wheel 3 walks on the pit block, it can ensure that the deep excavator walks smoothly without affecting the working effect.

[0065] Furthermore, if Figure 7 As shown, a plurality of second connecting holes 81 are provided on the top of the bracket 8 along its height direction, and a second connecting member is provided on the frame 1. The second connecting member can be a connecting plate fixed on both sides of the frame 1, and the second connecting member is provided with a second through hole.
