Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery and equipment technology, specifically a vacuum cleaner for agricultural seeders. Background Technology
[0002] During the sowing process, a lot of dust is generated. In order to prevent this dust from entering the machine and affecting its service life, a vacuum cleaner is installed to remove the dust.
[0003] Chinese patent CN207732544U discloses a vacuum cleaner for an agricultural seeder. The lower end cover of the vacuum cleaner has an annular groove coaxial with the shaft hole at its bottom periphery. A dust cap is fixed to the lower end of the rotating shaft, with a protruding ring on top that mates with the annular groove. When the motor is running, the dust cap rotates synchronously with the impeller. Because of the protruding ring and annular groove between the dust cap and the lower end cover, it is difficult for dust to enter the motor. Simultaneously, the centrifugal force generated when the dust cap rotates causes a small portion of the dust to be thrown out, greatly reducing dust entering the motor and extending its service life.
[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: The rotor of this patent is composed of magnetic tiles and upper and lower steel sleeves. Although the outer diameter of the rotor is reduced, centrifugal force is generated when the rotating shaft of this patent rotates at high speed. The centrifugal force increases with the increase of the rotating shaft speed, which poses a risk of the magnetic tiles loosening or falling off.
[0005] To address the problems raised in the background art, those skilled in the art have proposed a vacuum cleaner for agricultural seeders. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a vacuum cleaner for agricultural seeders, which solves the problem that the rotor in the prior art is composed of magnetic tiles and upper and lower steel sleeves. Although the outer diameter of the rotor is reduced, centrifugal force is generated when the shaft of this patent rotates at high speed. The centrifugal force increases with the increase of the shaft speed, which poses a risk of the magnetic tiles loosening or falling off.
[0007] A vacuum cleaner for an agricultural seeder includes a motor, an impeller connected to the motor, a wind shield connected to the motor, the impeller being located inside the wind shield, and a shielding component connected to the wind shield.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0024] Example 1
[0025] As attached Figure 1 To be continued Figure 3 As shown in the figure, this embodiment provides a vacuum cleaner for an agricultural seeder, including a motor 1, an impeller connected to the motor 1 (not shown in the figure), wherein the motor 1 is used to drive the impeller to rotate, the motor 1 is connected to a wind mask 2, the impeller is located inside the wind mask 2, wherein the wind mask 2 is used to protect the impeller and prevent the impeller from hitting hard objects when rotating, and the wind mask 2 is connected to a shielding component 3, wherein the shielding component 3 prevents roots and stems from being sucked into the wind mask 2 and getting tangled on the impeller;
[0026] The motor 1 includes a housing 101. Heat-dissipating fins are provided on the outer wall of the housing 101 to improve the heat dissipation efficiency of the motor 1. An upper end cover 102 and a lower end cover 103 are connected to the two ends of the housing 101, respectively. The housing 101, the upper end cover 102, and the lower end cover 103 cooperate to form a relatively sealed environment, protecting the internal components. A rotating shaft 104 and a stator 105 are provided inside the housing 101. The stator 105 is mounted on the inner wall of the housing 101. A mounting sleeve 106 is provided around the rotating shaft 104. Mounting grooves 107 are formed around the mounting sleeve 106. The cross-section of several mounting grooves 107 is an isosceles trapezoid, forming a narrow opening to prevent the magnetic tiles from loosening or falling off due to centrifugal force. Magnetic tiles (not shown in the diagram) are installed inside the mounting grooves 107. A winding groove 108 is provided on the stator 105 for embedding wires, simplifying the manufacturing process.
[0027] As can be seen from the above, when the motor 1 is working, the rotating shaft 104 drives the mounting sleeve 106 to rotate. Due to the special shape of the mounting groove 107, a narrow opening is formed, which has a limiting effect on the magnetic tile. This can prevent the centrifugal force generated by the rotation of the rotating shaft 104 from causing the magnetic tile to loosen or fall off, thus ensuring the service life of the motor 1.
[0028] Example 2
[0029] As attached Figure 2 To be continued Figure 3As shown, this embodiment is basically the same as the previous embodiment, except that the winding groove 108 is provided with eighteen grooves, the mounting sleeve 106 has six surfaces, the mounting sleeve 106 and the magnetic tile form the rotor, the stator 105 has a diameter of 27m, an inner diameter of 17m, and an outer diameter of 16m.
[0030] Specifically, the rotating shaft 104 is connected to the upper end cover 102 and the lower end cover 103 through bearings. The bearings ensure that the rotating shaft 104 can rotate normally. The rotating shaft 104 extends downward through the lower end cover 103 and into the wind mask 2. The part of the rotating shaft 104 that extends into the wind mask 2 is connected to the impeller. The stator 105 is fixed to the inner wall of the outer casing 101.
[0031] Furthermore, an air inlet 4 is provided at the end of the wind mask 2 away from the motor 1, and several air outlets 5 are provided around the wind mask 2. The air inlet 4 and the air outlets 5 work together to form an air duct.
[0032] As can be seen from the above, when motor 1 is working, the rotating shaft 104 drives the impeller to rotate, and the rotating impeller drives the air flow. The air enters from the air inlet 4 and exits from the air outlet 5.
[0033] Example 3
[0034] As attached Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the shielding component 3 includes a bolt 301 inserted into the wind mask 2. One end of the bolt 301 inserted into the wind mask 2 is connected to a nut 302. The shielding net 303 is installed on the wind mask 2 by the cooperation of the bolt 301 and the nut 302. The shielding net 303 is movably connected to the other end of the bolt 301 located outside the wind mask 2. The shielding net 303 and the air inlet 4 are located on the same axis. The shielding net 303 intercepts the roots and stems to prevent them from being sucked into the wind mask 2.
[0035] Specifically, the shielding component 3 also includes a spring 304, which is sleeved around the bolt 301. The two springs 304 are located at the two ends of the shielding net 303. The operation of the motor 1 and the seeder will generate vibrations, which will cause the springs 304 to deform continuously, thereby causing the shielding net 303 to vibrate back and forth, which can shake off the roots and stems on the shielding net 303 and prevent the shielding net 303 from being blocked.
[0036] As can be seen from the above, the shielding net 303 is installed on the wind mask 2 by the cooperation of bolt 301 and nut 302. The shielding net 303 intercepts the roots and stems to prevent them from being sucked into the wind mask 2. The operation of motor 1 and seeder will generate vibration. This vibration causes spring 304 to deform continuously, which in turn causes the shielding net 303 to vibrate back and forth, which can shake the roots and stems off the shielding net 303 and prevent the shielding net 303 from being blocked.
