Wherein, adjust shell 2 partly by accept in shell 1 inboard, partly stretch out from the discharge gate 11 of shell 1 downside, rotatory adjust shell 2 can adjust its length that stretches out from discharge gate 11, and the adjustment shell 2 stretches out longer, and it is the angle that discharge gate 11 sheltered from is bigger, and the angle that the material broadcast is the time is less. Specifically, before use, the projecting amount of the adjusting shell 2 is adjusted according to actual working conditions (such as the height and shape of crops, and other influencing factors), and then the adjusting shell 2 is fixed.

Based on the above adjustable scattering angle's the device of scattering, install rotatable adjustment shell 2 on the shell 1 of the device of scattering, adjustment shell 2 can shelter from the part of discharge gate 11, can adjust the size of the angle that shelters from discharge gate 11 through rotating adjustment shell 2, and the material can't be followed the position that discharge gate 11 was sheltered from when scattering the operation and spill, can adjust the scattering angle of the device of scattering through adjustment shell 2 promptly. Therefore, the sowing device of the scheme can freely adjust the sowing angle according to actual operation requirements, and meets the requirements of operation adjustment of the sowing angle under different conditions.

In some embodiments, the casing 1 includes an arc-shaped plate 12 and first and

second side plates

13 and 14 connected to opposite sides of the arc-shaped plate 12, and the discharge port 11 is formed between the first and

second side plates

13 and 14; the adjusting housing 2 comprises an arc-shaped baffle 21 corresponding to the arc-shaped plate 12, and a first side baffle 22 and a second side baffle 23 connected to two opposite sides of the arc-shaped baffle 21, and the slinger 4 is positioned between the first side baffle 22 and the second side baffle 23.

Specifically, the adjusting shell 2 is provided with a volute-shaped structure similar to the shape of the shell 1, so that enough space can be reserved to the greatest extent on the inner side for the operation of the throwing disc 4 while the requirement of shielding the discharge hole 11 is met; avoiding the adjustment housing 2 from interfering with the operation of the slinger 4.

In some embodiments, referring to fig. 1-2, to achieve locking of the adjustment housing 2, the outer housing 1 is provided with a positioning member 3 for fixing the adjustment housing 2.

Therefore, after the angle of the adjusting shell 2 is adjusted, the adjusting shell 2 is locked by the positioning piece 3, so that the problem that the adjusting shell 2 rotates by itself to change the seeding angle and even prevent normal seeding can be avoided.

Preferably, the positioning member 3 includes a positioning bolt and a positioning nut, and the adjusting housing 2 is provided with a positioning hole 24 corresponding to the positioning bolt, and the positioning bolt passes through the housing 1 and the positioning hole 24 and is connected with the positioning nut, so as to lock the adjusting housing 2 on the housing 1.

Further, the positioning member 3 is provided on the first side plate 13 and/or the second side plate 14 of the housing 1, and the positioning hole 24 is provided on the first side plate 22 and/or the second side plate 23.

Meanwhile, the locating piece 3 with the structure is simple in structure, easy to realize, convenient to assemble and disassemble and beneficial to the adjustment operation of the adjustment shell 2.

In order to achieve the adjusting function, as an achievable manner, the positioning hole 24 is an arc-shaped long hole, and the positioning bolt can slide in the arc-shaped long hole by loosening the positioning nut, so that the angle of the adjusting shell 2 for shielding the discharge hole 11 is adjusted.

Specifically, by adopting the arc long hole structure, the positioning bolt can slide along the arc long hole relative to the adjusting shell 2, so that the positioning nut and the positioning bolt are not required to be completely detached when the adjusting shell 2 is rotated, the positioning nut is only required to be loosened, the adjusting shell 2 is not pressed any more, the adjusting shell 2 is then rotated to a proper angle, and the positioning nut is then tightened again. It is understood that the positioning holes 24 are provided as arc-shaped long holes to facilitate the adjustment operation of the adjustment housing 2.

As another implementation manner, the positioning holes 24 are a plurality of through holes alternately distributed on the adjusting shell 2, and the angle of the adjusting shell 2 for shielding the discharge hole 11 is adjusted by connecting the positioning pieces 3 with the positioning holes 24 at different positions.

Specifically, in this way, after the positioning bolt passes through any positioning hole 24, a limit is formed between the positioning bolt and the positioning hole 24, and the adjusting shell 2 cannot move relative to the positioning bolt, so that the problem that the adjusting shell 2 freely slides to change the spreading angle when the positioning nut is loosened can be avoided. In this way, before the adjustment housing 2 is rotated, the positioning bolt needs to be completely removed and adjusted to a desired angle, and then the positioning bolt and the positioning nut are installed.

Specifically, in the free state, the external dimension of the adjusting shell 2 is larger than the dimension of the inner wall of the shell 1, after the adjusting shell 2 is plugged into the shell 1, the adjusting shell 2 freely stretches to be tightly attached to the inner wall of the shell 1 and applies certain elastic pressure to the shell 1, and the friction resistance between the adjusting shell 2 and the shell 1 can be increased by utilizing the elastic pressure, so that the aim of fixing the adjusting shell 2 in the shell 1 is fulfilled.

Further, the adjusting housing 2 is provided with a plurality of concave portions 25, and the concave portions 25 increase the resilience of the adjusting housing 2, so as to increase the friction resistance between the adjusting housing 2 and the housing 1.

Specifically, the concave portion 25 is disposed at the arc-shaped baffle 21 and extends to the first side baffle 22 and the second side baffle 23 toward two sides, and the bending structure of the adjusting shell 2 can be increased based on the disposition of the concave portion 25, so as to increase the elastic pressure of the arc-shaped baffle 21 to the first side plate 13 and the second side plate 14 at two sides. According to the principle that the larger the pressure is, the larger the friction resistance is, the pressure of the adjusting shell 2 to the inner wall of the shell 1 is increased, so that the friction resistance between the adjusting shell 2 and the shell can be increased, and the stability of the adjusting shell 2 is further improved.

In the sowing device of this embodiment, the motor 5 connected with the throwing disc 4 is installed on the first side plate 13, and a feeder (not shown) is installed on the second side plate 14, so that materials are pushed into the sowing cavity by the feeder, and the throwing disc 4 is driven to operate by the motor 5 to realize automatic sowing.
