Description

Technical Field

[0001] This utility model relates to the field of spherical fruit feeding technology, specifically an automatic sorting and feeding machine for spherical fruits. Background Technology

[0002] Spherical fruits are fruits that are nearly spherical. When processing spherical fruits, a feeding machine is needed to neatly arrange and feed them, making the feeding process more convenient and faster. This feeding machine is mainly used for feeding spherical fruits that are similar in size to figs.

[0003] Patent document CN206255583U discloses a fruit feeding machine, which includes "a frame, a conveying device, a discharging device, a storage bin, and a motor; the motor is located at one end of the conveying device; the frame has an L-shaped structure, with the conveying device located at the upper end of the frame; the storage bin is a square three-dimensional container located at the parallel end of the frame; the discharging device is connected to the conveying device and is located at the other end of the conveying device opposite to the motor; the conveying device has an L-shaped structure, with its parallel end located at the parallel end of the frame and inside the storage bin, and its inclined end located at the inclined end of the frame. This invention overcomes the time-consuming and labor-intensive nature of traditional manual feeding, and also overcomes the disadvantages of needing to continuously add material when feeding multiple messy fruits simultaneously, which damages the surface of the fruit, thus reducing waste caused by fruit damage."

[0004] However, the aforementioned published document on a fruit feeding machine mainly addresses the problem that existing fruit feeding machines are prone to damaging the fruit during use. However, the feeding box and feeding components of this fruit feeding machine are not easily separated, making the feeding machine inconvenient to handle or move.

[0005] In view of this, it is necessary to develop an automatic sorting and feeding machine for spherical fruits, so that the feeding machine can be easily disassembled and moved. Utility Model Content

[0006] The purpose of this invention is to provide an automatic sorting and feeding machine for spherical fruits to solve the technical problem mentioned in the background art, which is that the lack of fire extinguishing components leads to low safety of new energy vehicles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic sorting and feeding machine for spherical fruits, comprising: a feeding box, wherein a docking assembly is installed on the bottom back of the feeding box, the docking assembly comprising a fixed shell, a fixed screw, a limiting groove, a feeding rack assembly, a positioning block, a limiting block, and a fixing hole, the fixed shell being installed on the bottom back of the feeding box, the fixed screw being symmetrically installed through the back of the fixed shell, the limiting groove being symmetrically opened on the inner walls of both sides of the fixed shell, the positioning block being installed on the back of the feeding rack assembly, the fixing hole being opened on the back of the positioning block, the limiting block being symmetrically installed on both sides of the positioning block, the back of the feeding rack assembly being inserted into the interior of the fixed shell through the positioning block and installed at the bottom of the feeding box, and the limiting block being slidably located inside the limiting groove.

[0008] Preferably, the bottom center of the feeding box has a feeding port, which is located above the feeding rack assembly.

[0009] Preferably, a support frame is installed at the bottom of the feeding box, and a locking wheel is installed at the bottom of the support frame.

[0010] Preferably, the inner side of the feeding rack assembly is equipped with multiple feeding shafts, and a transmission housing connected to the feeding shafts is installed on one side of the feeding rack assembly. A drive motor is installed on one side of the transmission housing by bolts, and the output end of the drive motor is connected to the internal chain transmission assembly of the transmission housing. The chain transmission assembly includes a transmission gear, a transmission chain, and a connecting key. The transmission gear is installed inside the transmission housing, the transmission chain meshes with the outer side of the transmission gear, and the connecting key is installed on the outer side of the transmission chain and connected to the feeding shaft.

[0011] Preferably, a receiving head is installed on one inner wall of the feeding rack assembly, and a transmitting head corresponding to the receiving head is installed through one side of the feeding rack assembly.

[0012] Preferably, the bottom of the feeding rack assembly is equipped with a support leg, and a control panel is installed on one side of the support leg.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when the feeding rack assembly and the feeding box are connected, the positioning block is inserted into the inside of the fixed shell and the limiting block enters the inside of the limiting groove, so that the positioning block is stably inserted into the inside of the fixed shell. Then, the fixing screw is rotated into the inside of the fixing hole to fix the positioning block, thereby fixing the feeding box and the feeding rack assembly. When it is necessary to move the feeding machine, the fixing screw is rotated out and the positioning block is no longer positioned, so that the positioning block can be moved out of the fixed shell, and the feeding rack assembly is separated from the feeding box, which facilitates the movement and handling of the feeding machine.

[0015] 2. In this utility model, the receiver head is used to receive the infrared light emitted by the transmitter head. The transmitter head converts the electrical signal into an infrared beam and emits it. The receiver head is responsible for detecting the emitted beam. When the fruit enters the beam path, it will block part or all of the light, causing the receiver head to detect a signal change. The receiver head converts the light signal into an electrical pulse, which triggers the counting circuit in the control panel to count. The count is displayed on the screen in the control panel, giving the feeding machine a counting function. Attached Figure Description

The limiting groove 7 is symmetrically opened on the inner walls of both sides of the fixed shell 5. The positioning block 15 is installed on the back of the feeding rack assembly 8. The fixing hole 17 is opened on the back of the positioning block 15. The limiting block 16 is symmetrically installed on both sides of the positioning block 15. The back of the feeding rack assembly 8 is inserted into the inside of the fixed shell 5 through the positioning block 15 and installed at the bottom of the feeding box 1. The limiting block 16 slides inside the limiting groove 7. A feeding port 2 is opened at the middle position of the bottom of the feeding box 1 and is located above the feeding rack assembly 8. A support frame 3 is installed at the bottom of the feeding box 1. A locking wheel 4 is installed at the bottom of the support frame 3.

[0027] The feeding box 1 provides space for storing spherical fruits and also provides an installation position for the docking assembly. The feeding rack assembly 8 is connected to the feeding box 1 via the docking assembly. When docking the feeding rack assembly 8 and the feeding box 1, the positioning block 15 is inserted into the inside of the fixed shell 5 and then enters the inside of the limiting groove 7 through the limiting block 16, so that the positioning block 15 is stably inserted into the inside of the fixed shell 5. Then, the fixing screw 6 is rotated into the fixing hole 17 to fix the positioning block 15, thereby fixing the feeding box 1 and the feeding rack assembly 8. When it is necessary to move the feeding machine, the fixing screw is... 6. Rotate to remove and no longer position the positioning block 15, so that the positioning block 15 can be moved out of the fixed shell 5, so that the feeding rack assembly 8 is separated from the feeding box 1, making it easy to move and transport the feeding machine. The bottom of the feeding box 1 is supported by the support frame 3. Under the action of the locking wheel 4, it is easy to move the feeding box 1 after disassembly. The feeding port 2 allows the fruit in the feeding box 1 to enter the feeding rack assembly 8. The locking wheel 4 is a 4-inch universal wheel (2 with brakes, 2 with free steering). The wheel frame is connected to the support frame (3) by M10 bolts. The load capacity is ≥100kg / wheel. The braking mechanism is a foot pedal metal caliper.

[0028] Please see Figure 1 , Figure 3 and Figure 5 An automatic sorting and feeding machine for spherical fruits;

[0029] The assembly includes a feeding rack assembly 8, a receiving head 13, and a transmitting head 14. Multiple feeding shafts 18 are installed inside the feeding rack assembly 8. A transmission housing 11 connected to the feeding shafts 18 is installed on one side of the feeding rack assembly 8. A drive motor 12 is bolted to one side of the transmission housing 11, and the output end of the drive motor 12 is connected to the internal chain drive assembly of the transmission housing 11. The chain drive assembly includes a transmission gear 19, a transmission chain 20, and a connecting key 21. The transmission gear 19 is installed inside the transmission housing 11, the transmission chain 20 meshes with the outside of the transmission gear 19, and the connecting key 21 is installed on the outside of the transmission chain 20 and connected to the feeding shafts 18. A receiving head 13 is installed on the inner wall of one side of the feeding rack assembly 8. A transmitting head 14 corresponding to the receiving head 13 is installed through one side of the feeding rack assembly 8. A support leg 9 is installed at the bottom of the feeding rack assembly 8, and a control panel 10 is installed on one side of the support leg 9.

[0030] When using the feeding rack assembly 8, the drive motor 12 is turned on, and the drive motor 12 drives the chain in the transmission housing 11 to run, so that the chain drives the feeding shaft 18 to run. The fruit is located between the feeding shafts 18 and is fed by the running of the feeding shafts 18. The end of the feeding shaft 18 is connected to the transmission chain 20 through the connecting key 21. The phase difference of each shaft sprocket is 15° to reduce the starting torque. The transmission housing 11 adopts a split aluminum alloy housing, and a 0.5mm thick fluororubber sealing strip is added to the mating surface. The feeding shaft (18) adopts a 20mm diameter stainless steel roller, and the surface is covered with a 3mm thick silicone layer (Shore hardness 5). 0A) To increase friction; the shafts are arranged in parallel with a center-to-center distance of 35mm (suitable for spherical fruits with a diameter of 40-80mm), and the axial direction is inclined at a 15° angle to the horizontal plane. The drive motor 12 drives all the feeding shafts to rotate synchronously through a double-row roller chain (pitch 12.7mm) in the transmission housing 11. The feeding rack assembly 8 provides an installation position for the infrared counting structure. The infrared counting structure includes a transmitter 14, a receiver 13, and a control panel 10. The receiver 13 is used to receive the infrared rays emitted by the transmitter 14. The transmitter 14 converts the electrical signal into an infrared beam for emission. 3 is responsible for detecting the emitted light beam. When fruit enters the beam path, it blocks part or all of the light, causing receiver 13 to detect a signal change. Receiver 13 converts the light signal into electrical pulses, triggering the counting circuit in control panel 10 to count. The count is displayed on the screen in control panel 10, enabling the feeder to have a counting function. The infrared counting function is achieved through a through-beam photoelectric sensor between transmitter 14 and receiver 13. Transmitter 14 uses a 940nm infrared LED to modulate the emitted beam at a 5kHz frequency, and receiver 13 has a built-in demodulation circuit. To avoid ambient light interference, the system only responds to signals of the same frequency. The signal processing logic is as follows: when fruit passes through the gap in the feeding shaft 18, the beam is blocked, causing the signal strength of the receiver head 13 to drop to a threshold (preset to 30% of the initial value), triggering a counting pulse. The control panel 10 has a built-in STM32 microcontroller that uses a hardware de-jitter circuit (RC filter time constant 10ms) to eliminate signal jitter caused by mechanical vibration. Continuous blocking is determined by the following: if the signal interruption duration is >50ms (corresponding to a fruit diameter ≥60mm passing speed of 0.3m / s), it is counted as a single fruit to avoid duplicate counting. False counting prevention design: the distance between the transmitter head 14 and receiver head 13 is set to 80mm, installed 10cm from the end of the feeding shaft, ensuring that counting is triggered only after the fruit leaves the rolling state between the shafts. Dual-beam redundancy design: two sets of sensors are arranged in a V-shape, counting only occurs when both beams are blocked simultaneously, preventing lateral missed detections.

[0031] Working principle: First, the feeding machine is installed in the required position. The feeding rack assembly 8 in the feeding machine is connected to the feeding box 1 through the docking assembly. The fruits that need to be sorted and fed are placed into the inside of the feeding box 1. The feeding rack assembly 8 is opened and used through the control panel 10, so that the feeding shaft 18 moves. The fruits in the feeding box 1 fall into the feeding shaft 18 through the feeding port 2. The fruits are fed by the movement of the feeding shaft 18.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
