Description

Technical Field

[0001] The utility model relates to the technical field of fruit pickers, in particular to a fruit picker with adjustable frequency. Background Technique

[0002] A fruit picker is a mechanical device for picking fruits. The fruit picker with adjustable frequency you mentioned may refer to a machine with the function of adjusting the working frequency. Such a design can adjust the vibration frequency and intensity of the machine according to different fruit tree species and tree ages, so as to pick fruits more effectively. By adjusting the frequency, the fruit picker can be optimized according to different fruit types and different tree ages. For example, for ripe fruits, a higher frequency and vibration intensity can be used to quickly pick the fruits. For more delicate fruits or young fruit trees, the frequency and vibration intensity can be reduced to avoid damaging the fruits or trees. This fruit picker with adjustable frequency helps to improve the mechanical picking efficiency and reduce waste and damage.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a fruit picker with adjustable frequency, including a mounting frame 1, a rubber plate 2 fixedly connected to the side wall of the mounting frame 1, two symmetrically distributed shoulder straps 3 fixedly connected to the side wall of the mounting frame 1, a power supply box 4 arranged at the upper end of the mounting frame 1, a connecting wire 7 inserted into the interior of the power supply box 4, and a fruit picking component 8 for picking fruits arranged at one end of the connecting wire 7.

[0025] The fruit picking component 8 includes a mounting shell 81 fixedly installed at one end of the connecting wire 7, a handle 82 fixedly connected to the upper end of the mounting shell 81, a control button 83 arranged inside the handle 82, a receiver 84 arranged inside the mounting shell 81, a speed regulator 85 arranged inside the mounting shell 81, the speed regulator 85 being electrically connected to the connecting wire 7, a motor 86 arranged inside the mounting shell 81, a rotating frame 87 fixedly connected to the output shaft of the motor 86, and the rotating frame 87 being rotatably connected to the mounting shell 81.

[0026] Exemplarily, the speed regulation formula of a DC motor can be expressed as: N = (U - laRa) / kp;

[0027] Among them, N is the rotational speed of the motor, U is the power supply voltage of the motor, la is the armature current of the motor, Ra is the armature resistance, k is the torque constant of the motor, and φ is the magnetic flux of the motor;

[0028] According to this formula, it can be seen that there is a relationship between the rotational speed of the DC motor and the power supply voltage, the armature current of the motor, and the magnetic flux. When the power supply voltage or the armature current increases, the rotational speed of the motor 86 will also increase accordingly. Conversely, when the power supply voltage or the armature current decreases, the rotational speed of the motor 86 will also decrease accordingly. At the same time, when the magnetic flux increases, the rotational speed of the motor 86 will decrease, and conversely, when the magnetic flux decreases, the rotational speed of the motor 86 will increase.

[0029] The receiver 84 is electrically connected to the control button 83 and the speed regulator 85 respectively.

[0030] Exemplarily, the receiver 84 is controlled by increasing or decreasing the pressing force on the control button 83.

[0031] Two symmetrically distributed sub - stickers 5 are fixedly connected to the side wall of the mounting bracket 1, and mother - stickers 6 are bonded to the outer sides of the two sub - stickers 5.

The sun - shading component 9 includes a telescopic rod 91 fixedly installed on the side wall of the mounting bracket 1. A lifting block 92 is fixedly connected to the output end of the telescopic rod 91. Two symmetrically distributed limiting rods 93 are fixedly connected to the upper end of the lifting block 92. A baffle 94 is slidably connected to the outer sides of the two limiting rods 93, and a folding plate 95 is rotatably connected to one end of the baffle 94.

[0035] The telescopic rod 91 controls the height of the lifting block 92, the limiting rod 93 limits the baffle 94, and the folding plate 95 can increase the sun - shading range.

[0036] Sockets are opened on the side walls of the folding plate 95 and the baffle 94, and limiting plates 96 are inserted into the interiors of the sockets.

[0037] The limiting plate 96 is inserted into the interior of the socket to fix the folding plate 95 and the baffle 94, preventing rotation between the folding plate 95 and the baffle 94 during use.

[0038] A fixing bolt 97 is threadedly connected to the interior of the lifting block 92, and the fixing bolt 97 is rotatably connected to the baffle 94.

[0039] The fixing bolt 97 fixes the baffle 94 by cooperating with the lifting block 92.

[0040] The working principle of the present utility model is as follows: When the present utility model is in use, the mounting frame 1 is carried on the back through the shoulder strap 3, and the fruit is picked by holding the handle 82. The control button 83 provided at the lower end of the handle 82 controls the rotation frequency of the rotating frame 87. By increasing or decreasing the pressing force on the control button 83, the receiver 84 is controlled. The receiver 84 will control the speed governor 85, and the speed governor 85 controls the current supplied to the supply motor 86, facilitating the motor 86 to rotate at different frequencies. The motor 86 drives the rotating frame 87 to rotate, and the rotating frame 87 picks the fruits. The power supply box 4 provides current for the operation of the device, and the connecting wire 7 transports the current.

[0041] The telescopic rod 91 controls the height of the lifting block 92, the limiting rod 93 limits the baffle 94, the folding plate 95 can increase the sunshade range, the limiting plate 96 is inserted into the interior of the jack to fix the folding plate 95 and the baffle 94, preventing rotation between the folding plate 95 and the baffle 94 during use.
