Description

Technical field:

[0001] The utility model relates to the technical field of seed drills, in particular to a deep fertilization device. Background technology:

[0002] The rotary tillage, fertilization and sowing machine is an agricultural machinery that integrates multiple functions such as rotary tillage, fertilization and sowing. It can significantly improve agricultural production efficiency and reduce farmers' labor intensity.

[0003] At present, the rotary tillage, fertilization and sowing machines all-in-one sprinkle the fertilizer in front of the machine, and then sow it into the ground under the rotary tillage action of the machine. This will cause part of the fertilizer to fall on the surface and shallow layer, evaporate and disappear, causing great waste. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model aims to provide a tubular fertilizing leg with an arc-shaped lower portion to solve the problem that part of the fertilizer falls on the surface and the shallow layer and evaporates and disappears, causing great waste.

[0005] In order to solve the problems of the prior art, the technical solution of the utility model is as follows: a deep fertilization device, comprising a seed drill frame and a fertilization leg, the outer wall of the fertilization leg is fixedly connected to a mounting plate, the outer wall of the seed drill frame is connected to a mounting seat through a square clamping bolt, the outer wall of the mounting seat is provided with an adjustment groove, the inner wall of the adjustment groove is slidably connected to a mounting bolt, the mounting bolt passes through the mounting plate and is slidably connected to the mounting plate, and the outer wall of the mounting bolt is threadedly connected to a fixing nut.

[0006] Preferably, the fertilizing leg is a tubular structure with an arc-shaped lower portion, and is used to apply fertilizer into deep underground layers.

[0007] Preferably, the mounting plate is located on the outer wall of the fertilizing leg near the top, and the outer wall of the mounting plate is provided with two slots for the mounting bolts to pass through. There are two upper and lower adjustment slots, and each adjustment slot corresponds to a mounting bolt connected to adjust the height of the fertilizing leg.

[0008] Preferably, the outer wall of the mounting seat is provided with two pairs of slots for square clamping bolts to pass through, and the slots are symmetrical in pairs, and the square clamping bolts are sleeved on the outer wall of the seed drill frame.

[0009] Preferably, the outer wall of the seed drill frame is fixedly connected with a fixing seat, and the outer wall of the fixing seat is connected to the mounting plate through an adjustment groove and mounting bolts.

[0010] Compared with the prior art, the advantages of the utility model are as follows:

[0011] The utility model installs tubular fertilizing legs with an arc-shaped lower portion on the seeding machine frame, so that fertilizer can be applied into the deep underground layer in strips like sowing, which greatly saves fertilizer and avoids the situation where part of the fertilizer falls on the surface and the shallow layer and evaporates and disappears, causing great waste. The fertilizer in the deep layer can be released slowly, which increases the utilization rate of the fertilizer, promotes the downward growth of the root system, and resists lodging.

[0012] The utility model installs the fertilizing leg to the seeding machine frame by arranging an adjusting groove and a mounting bolt, and the height of the fertilizing leg can be adjusted. Since the planting depths of seeds of different crops are different, the fertilizing leg with adjustable height can more accurately apply fertilizer around the seeds according to actual conditions, thereby effectively increasing the utilization rate of the fertilizer.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1

[0021] See also Figure 1-3A deep fertilization device comprises a seeding machine frame 1 and a fertilization leg 2. The fertilization leg 2 is a tubular structure with an arc-shaped lower portion for applying fertilizer into the deep underground layer. The outer wall of the fertilization leg 2 is fixedly connected with a mounting plate 3. The outer wall of the seeding machine frame 1 is connected with a mounting seat 4 through a square clamping bolt. The outer wall of the mounting seat 4 is provided with two pairs of notches for the square clamping bolts to pass through, and the two are symmetrical. The square clamping bolts are sleeved on the outer wall of the seeding machine frame 1. The outer wall of the mounting seat 4 is provided with an adjusting groove 5. The inner wall of the adjusting groove 5 is slidably connected with a mounting bolt 6. The mounting bolt 6 penetrates the mounting plate 3 and is slidably connected to the mounting plate 3. The outer wall of the mounting bolt 6 is threadedly connected with a fixing nut 7. Specifically, the seeding machine frame 1 is located in a rotary tillage fertilization sowing machine. The mounting frame on the rotary tillage fertilizing and sowing machine is used to evenly mount multiple fertilizing legs 2. There are two fertilizer inlets on the top of the fertilizing legs 2 for applying different fertilizers into the ground. The fertilizer inlets correspond to the positions of the fertilizer box outlets on the rotary tillage fertilizing and sowing machine. The square clamp bolts and nuts threadedly connected thereto are used to fix the mounting seat 4 to the seeding machine frame 1. By installing the tubular fertilizing legs 2 with an arc-shaped lower portion on the seeding machine frame 1, fertilizer can be applied into the deep underground layer in strips like sowing, which greatly saves fertilizer and avoids the situation where part of the fertilizer falls on the surface and shallow layer and evaporates and disappears, causing great waste. The deep fertilizer can be released slowly, which increases the utilization rate of the fertilizer, promotes the downward growth of the root system, and resists lodging.

[0022] See also Figure 1-3 The mounting plate 3 is located on the outer wall of the fertilizing leg 2 near the top. The outer wall of the mounting plate 3 is provided with two notches for the mounting bolts 6 to pass through. There are two upper and lower adjusting grooves 5, and each adjusting groove 5 is connected to a mounting bolt 6 corresponding to the height of the fertilizing leg 2. Specifically, when the height of the fertilizing leg 2 needs to be adjusted, the fixing nut 7 is first rotated to loosen the mounting plate 3 and the mounting seat 4, and then the height of the fertilizing leg 2 is moved according to the required fertilization depth. At the same time, the fertilizing leg 2 will slide along the inner wall of the adjusting groove 5 with the mounting bolt 6. After the fertilizing leg 2 moves to the required height, the fixing nut 7 is rotated to firmly install the mounting plate 3 and the mounting seat 4. The fertilizing leg 2 is installed with the seeding machine frame 1 by setting the adjusting groove 5 and the mounting bolt 6, so that the height of the fertilizing leg 2 can be adjusted. Due to the difference in the planting depth of seeds of different crops, the fertilizing leg 2 with adjustable height can more accurately apply fertilizer around the seeds according to the actual situation, effectively increasing the utilization rate of the fertilizer.
