DETAILED DESCRIPTION

[0021] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the utility model.

[0022] like Figure 1 As shown, the utility model is a safflower harvester, referring to the attached Figure 1-4 It is mainly composed of a turbo fan 1, a handle 2, a shoulder strap fixing hole 3, a filament removal outlet 4, a sealed storage box 5, a reversing switch 6, a charging port 7, a main switch 8, a power display 9, a transparent hose 10, a clamp 11, a harvesting handle 12, a harvesting head 13, etc. A turbofan 1 is installed at the upper left exit of the sealed storage box 5. The air outlet of the turbofan 1 is backward to avoid blowing on the operator's head. The large air volume of the turbofan 1 forms a negative pressure area inside the sealed storage box 5. A filter is installed at the air inlet of the turbofan 1 to prevent part of the filaments from being sucked into the turbofan 1; a handle is provided just above the sealed storage box 5, which is convenient for carrying the sealed storage box 5; a shoulder strap fixing hole is also provided on the top of the sealed storage box 5, and the sealed storage box 5 can be carried on the back of the operator through the shoulder strap, which is convenient for operation; a filament removal outlet 4 is provided at the upper right of the sealed storage box 5, and the diameter of the filament removal outlet 4 can meet the needs of an adult's palm to reach in and grab the filaments. When picking safflower, this outlet is tightly covered with a lid to ensure the airtightness of the sealed storage box 5, and it is only opened when the filaments are taken out; a reversing switch 6 is installed on the right side of the bottom of the sealed storage box 5, and the reversing switch 6 mainly realizes the reversing of the reduction motor 20. When the reversing switch 6 is in the upper closed position, the output shaft of the reduction motor 20 rotates clockwise. The needle rotates, and when the reversing switch 6 is closed at the bottom, the output shaft of the reduction motor 20 rotates counterclockwise. The purpose of using the reversing switch 6 is to allow the blade 22 to achieve tangent and reverse cutting; a charging port 7 is installed next to the reversing switch 6, and the charging port 7 can charge the battery; a main switch 8 is installed next to the charging port 7, and the main switch 8 is responsible for the power supply control of the entire device. After closing, the turbo fan 1, the power display 9, and the reduction motor 20 are all powered on; a power display 9 is installed on the bottom rear side of the sealed storage box 5, which mainly indicates the power of the battery, reminds the operator how much remaining power is left, and charges when the power is low; a transparent hose 10 is installed on the top rear side of the sealed storage box 5. The transparent hose 10 can absorb the filaments from the harvesting head 13 into the sealed storage box 5 to achieve the transmission of negative pressure and the transmission of filaments; the tail end of the transparent hose 10 is connected to the harvesting head 13 through a clamp 11, and a harvesting handle 12 is provided at the tail end of the harvesting head 13, which is convenient for the operator to hold and use.

[0023] The bottom view and side view of the harvesting head 13 are as follows: Figure 2 , Figure 3As shown, an opening 14 is provided at the lower end of the harvesting head 13, and the opening 14 is a large and small notch, the large notch is V-shaped, and the small notch is rectangular. The large and small notches are conducive to the left hand to deliver the safflower bud 25. The width of the small notch is about 7mm, which is smaller than the diameter of the finger. In addition to preventing injury to the finger, the diameter of the part between the safflower bud 25 and the safflower filament 26 is generally less than 7mm. When the safflower filament 26 slides to this place, it will not shake too much left and right. After cooperating with the baffle 19, the safflower filament 26 is easy to cut off; the baffle 19 is installed at the lower end of the main shell of the harvesting head 13 through seven fixing screws 16, which is conducive to the cutting of the safflower filament 26 and can also protect the operator's fingers; a rotating shaft positioning hole 15 is provided in the middle of the baffle 19, which is used to limit the blade fixing shaft 23 and prevent the shaft from moving; the harvesting handle 12 is tightly connected to the harvesting head 13 through the harvesting handle fixing hole 17, and the tail of the harvesting handle 12 is provided with a harvesting handle suspension The hanging hole 18 is used for hanging the harvesting head 13 at a high place to prevent children from touching it; a reduction motor 20 is installed on the upper part of the harvesting head 13. In addition to providing torque, the reduction motor 20 also provides a certain speed to ensure that the cutting speed can be accelerated under the torque of cutting the safflower filaments 26, thereby improving the efficiency of safflower picking; the output shaft of the reduction motor 20 and the blade fixing shaft 23 are pressed and connected by a shaft locking screw 21, and the blade limiting plate 24 is connected to the blade fixing shaft 23. A blade 22 is fixed on the blade limiting plate 24. The blade limiting plate 24 cooperates with the two positioning holes on the blade 22 to achieve non-slip rotation and vibration of the blade. The blade 22 adopts a tungsten steel sheet with cutting edges on both sides, which is sturdy and durable. When the blade 22 rotates, it cuts the filaments sent in from the opening 14, and then the cut filaments are quickly sucked into the filament suction port 27 and collected into the sealed storage box 5 through the transparent hose 10.

[0024] The circuit diagram of the safflower harvester is as follows Figure 4As shown, the "CHARGE" socket is connected to the charging port 7, the first core of the charging port 7 is connected to the diode D1, and the diode D1 is connected to the positive electrode of the battery BT, and the second core of the "CHARGE" socket is connected to the negative electrode of the battery BT, so that charging can be achieved. Due to the reverse cutoff effect of the diode, the charging port will not have reverse current or cause a short circuit. Switch S1 is the main switch 8. After the switch S1 is closed, the socket DL and the socket FS are both powered on, the socket DL is connected to the power display 9, and the socket FS is connected to the turbo fan 1. The power display 9 indicates the current battery power, and the turbo fan 1 is running. Switch S2 is a reversing switch 6. When it is turned on upward, the output shaft of the reduction motor 20, i.e., B1, rotates clockwise. When it is turned on downward, the output shaft of the reduction motor 20 rotates counterclockwise, thereby realizing the forward and reverse rotation of the blade 22. The purpose of the forward and reverse rotation of the blade 22 is that when the blade on one side of the blade 22 becomes blunt due to a long cutting time, the cutting effect is reduced. At this time, the blade on the other side of the blade 22 is still very sharp. When the reversing switch 6 is turned to the other side, the blade on this side will participate in the cutting until the blades on both sides become blunt, and then the blade 22 can be replaced. The forward and reverse rotation of the blade 22 has no effect on the filament cutting.
