[0036] With the development of the economy and the progress of society, the automation of post-harvest processing of fruits and vegetables has become an inevitability and social consensus, and it is increasingly developing towards the characteristics of cost savings, convenience in use, space saving, safety and high efficiency. The fruit and vegetable packing machine, as an important link in the post-harvest processing of fruits and vegetables, is no exception. However, in the currently existing differential offset fruit dropping device, there is a risk of clamping and damaging fruits between the fan-shaped rubber support rod and the lower disc fruit dropping port. The larger the volume of the fruits and vegetables and the greater the quantity, the easier it is for the fruits and vegetables to be clamped and damaged. It is not applicable to the situation of packing fruits and vegetables with larger volume and more quantity, so the applicable range is small and the packing efficiency is low.

[0037] Based on this, please refer to Figure 1 and Figure 2 , the fruit dropping device 1000 provided in the embodiment of the present utility model can effectively solve the above-mentioned technical problems. The fruit dropping device 1000 can prevent the support rod 410 from clamping and damaging fruits, reduce the fruit damage rate, and can also expand the applicable range and improve the packing efficiency. The fruit dropping device 1000 in this embodiment is applied to a fruit and vegetable packing system, and the fruit and vegetable packing system including the fruit dropping device 1000 also has the above functions.

[0038] The fruit and vegetable packing system in this embodiment includes a conveying device and the fruit dropping device 1000, and the conveying device is connected to the fruit dropping device 1000. The conveying device conveys the fruits and vegetables to the fruit dropping device 1000, and the fruit dropping device 1000 puts the fruits and vegetables into the fruit box for packing. Of course, the fruit and vegetable packing system may also include other structures, such as a fruit and vegetable screening device, etc., to meet various requirements in the process of fruit and vegetable packing, which is not limited here.

[0039] Figure 1 is a schematic diagram of the first perspective of the fruit dropping device 1000 provided in the embodiment of the present utility model; Figure 2 is a schematic diagram of the second perspective of the fruit dropping device 1000 provided in the embodiment of the present utility model, as shown in Figure 1 and Figure 2As shown in the figure, the fruit dropping device 1000 in this embodiment includes a driving member 100, a fruit dropping tray 200, a transmission shaft 300, and a floating support rod 400. One end of the transmission shaft 300 is connected to the driving member 100, and the other end of the transmission shaft 300 is connected to the fruit dropping tray 200; the floating support rod 400 is movably connected to the side of the transmission shaft 300 close to the fruit dropping tray 200, and the floating support rod 400 can float back and forth along the axis direction of the transmission shaft 300. By providing the floating support rod 400, the floating support rod 400 is used to dial the fruits and vegetables falling into the fruit dropping tray 200 into boxes. In addition, the floating support rod 400 can float back and forth along the axis direction of the transmission shaft 300, that is, the floating support rod 400 can change the distance between the floating support rod 400 and the fruit dropping tray 200 according to the size of the fruits and vegetables falling into the fruit dropping tray 200, thereby preventing the fruits and vegetables from being pinched and reducing the damaged fruit rate. And because the distance between the floating support rod 400 and the fruit dropping tray 200 can be changed according to the size of the fruits and vegetables, it can be applied to the boxing of fruits and vegetables of various sizes, thus expanding the applicable range and improving the boxing efficiency.

[0040] The fruit dropping tray 200 is fixedly connected to the transmission shaft 300, so that the fruit dropping tray 200 does not rotate with the transmission shaft 300. The floating support rod 400 is drivingly connected to the transmission shaft 300, and the floating support rod 400 can rotate with the transmission shaft 300, so as to realize that the floating support rod 400 dials the fruits and vegetables falling into the fruit dropping tray 200 into the packing box.

[0041] In order to disperse the fruits and vegetables falling into the fruit dropping tray 200 and facilitate the floating support rod 400 to drive the fruits and vegetables out of the fruit dropping tray 200 for boxing, please continue to refer to Figure 1 and Figure 2 , the fruit dropping device 1000 in this embodiment further includes a differential assembly 900. The differential assembly 900 is located between the driving member 100 and the fruit dropping tray 200, and the differential assembly 900 is drivingly connected to the transmission shaft 300; the transmission shaft 300 is a differential shaft. The fruit dropping tray 200 is drivingly connected to both the floating support rod 400 and the transmission shaft 300, and the transmission shaft 300 can drive the fruit dropping tray 200 and the floating support rod 400 to rotate together at the same time. However, due to the cooperation of the differential assembly 900 and the differential shaft, coaxial differential can be realized, so that the rotation speeds of the fruit dropping tray 200 and the floating support rod 400 are different. By providing that the fruit dropping tray 200 can also rotate, the fruits and vegetables falling into the fruit dropping tray 200 can be dispersed and will not accumulate in one place, causing damage to the fruits and vegetables. The driving member 100 in this embodiment is a reduction motor. Of course, the driving member 100 can also use a motor or a motor with a lower rotation speed, which is not limited herein.

[0042] Specifically, the differential assembly 900 in this embodiment includes a first frame 910, a second frame 920, an auxiliary shaft 930, a first main gear 940, a second main gear 950, a first driven gear 960, and a second driven gear 970. The driving member 100 is installed on the first frame 910, and the transmission shaft 300 passes through the first frame 910. The second frame 920 is arranged at an axial interval from the first frame 910 along the transmission shaft 300. One end of the auxiliary shaft 930 is connected to the first frame 910, and the other end of the auxiliary shaft 930 passes through the second frame 920. The first main gear 940 is connected to the transmission shaft 300. The first driven gear 960 is connected to the auxiliary shaft 930 and meshes with the first main gear 940. Both the first main gear 940 and the first driven gear 960 are located between the first frame 910 and the second frame 920. The second main gear 950 is connected to the transmission shaft 300. The second driven gear 970 is connected to the auxiliary shaft 930 and meshes with the second main gear 950. Both the second main gear 950 and the second driven gear 970 are located below the second frame 920. And the total number of teeth of the first main gear 940 and the second main gear 950 is greater than the total number of teeth of the first driven gear 960 and the second driven gear 970. Using a double-layer frame for fixation can not only ensure the stability of the fixation of the transmission shaft 300 and the auxiliary shaft 930, guarantee the transmission accuracy of the gears, ensure the overall stability, but also simplify the structure, thus facilitating production and installation, and achieving cost reduction and efficiency improvement.

[0043] In this embodiment, the tooth ratio of the first main gear 940 to the first driven gear 960 is 2:1, and the second driving gear and the second driven gear 970 have the same number of teeth. Of course, the tooth ratio of the first main gear 940 to the first driven gear 960 can also be other proportional coefficients such as 1.5:1 or 3:1, etc., and the tooth ratio of the second driving gear to the second driven gear 970 can also be other proportional coefficients such as 1.5:1, 2:1, etc., which are not limited herein. It is specifically determined according to actual usage requirements, as long as it is ensured that the rotation speed of the floating strut 400 is greater than the rotation speed of the fruit dropping tray 200.

[0044] In addition, the differential assembly 900 can also be designed into other structures, such as a planetary gear structure, etc., as long as it can achieve coaxial differential between the fruit dropping tray 200 and the floating strut 400. What specific structure the differential assembly 900 includes is not limited herein.

[0045] Figure 3 For a partial schematic diagram of the fruit dropping device 1000 provided in the embodiment of the present utility model, please refer to Figure 2 and in combination with Figure 3In this embodiment, the floating strut 400 comprises a strut 410, a bearing block 420, a bearing 430, and a connecting plate 440. Each bearing block 420 is fixedly connected to the drive shaft 300, while the bearing 430 is connected to the bearing block 420. One end of the connecting plate 440 is movably connected to the bearing 430, and the other end of the connecting plate 440 is hingedly connected to the strut 410. A sleeve is provided at the junction between the drive shaft 300 and the floating strut 400, and the floating strut 400 is connected to the sleeve, forming a rotatable, movable rod. When the fruits and vegetables are large, the strut 410 is subjected to an upward force, causing it to rotate upward. Simultaneously, the connecting plate 440 also rotates upward around the bearing 430. When the force is removed, the strut 410 and connecting plate 440 fall back to their original position due to their own weight. The bearing block 420 and bearing 430 ensure a secure connection. The movable connecting plate 440 allows the strut 410 to float up and down along the axis of the drive shaft 300 as the connecting plate 440 rotates. Of course, the floating strut 400 may also include other structures, or be designed as other structural forms, as long as the strut 410 can float up and down along the axis of the transmission shaft 300 .

[0046] To prevent the support rod 410 from damaging the fruits and vegetables, the support rod 410 in this embodiment includes a rod body and a rod sleeve. The rod body is provided with a rod sleeve, and the rod body is connected to the connecting plate 440. To ensure the service life of the support rod 410, the rod body in this embodiment is made of aluminum. Of course, other corrosion-resistant materials can also be used, which is not limited here. The rod sleeve is made of a soft or elastic material, such as pearl cotton sleeve. By providing a soft rod sleeve outside the harder rod body, the support rod 410 can prevent damage to the fruits and vegetables during the process of moving them.

[0047] To improve packing efficiency, please continue to refer to Figure 2 , and combined with Figure 3 In this embodiment, there are multiple floating struts 400, and the multiple floating struts 400 are arranged at intervals around the transmission shaft 300. The multiple floating struts 400 are arranged at intervals, and two adjacent floating struts 400 divide the bottom plate 210 into a toggle zone. Each floating strut 400 can be responsible for the fruits and vegetables in the corresponding toggle zone, and multiple fruits and vegetables can be toggled and packed at the same time, thereby improving the packing efficiency. Specifically, the number of floating struts 400 in this embodiment is five, and the five floating struts 400 are evenly arranged around the transmission shaft 300, dividing the fruit tray 200 into five equal parts. Of course, the number of floating struts 400 can also be 1, 2, 3, 4, 6, etc., which is determined according to actual usage requirements and is not limited here.

[0048] In order to facilitate the cleaning and packaging of fruits and vegetables from the fruit drop tray 200 and to cushion the force of the fruits and vegetables falling, please refer to Figure 2 , and combined with Figure 3, in this embodiment, the fruit dropping tray 200 includes a bottom plate 210 and side plates 220, and the side plates 220 are arranged around the bottom plate 210; a notch 211 is formed in the bottom plate 210. By providing the notch 211, fruits and vegetables can fall into the packing box from this notch 211. In order to buffer the gravity of the fruits and vegetables falling into the packing box, a first fruit dropping rubber skin 500 is inclined at the notch 211 in this embodiment, and the first fruit dropping rubber skin 500 is used to buffer the falling fruits and vegetables. The first fruit dropping rubber skin 500 is a long rubber skin. After the fruits and vegetables fall from the notch 211, they fall onto the first fruit dropping rubber skin 500, decelerate and buffer, and then fall into the packing box. The number of the first fruit dropping rubber skins 500 in this embodiment is two, and the two fruit dropping rubber skins are stacked and crossed at the notch 211. Of course, the number of the first fruit dropping rubber skins 500 can also be three, four, etc., which is not limited herein.

[0049] To further protect the fruits and vegetables and prevent them from being damaged when falling into the fruit dropping tray 200, please continue to refer to Figure 2 , and in combination with Figure 3 , the fruit dropping device 1000 in this embodiment further includes a tray 600 and a plurality of second fruit dropping rubber skins 700. One end of the transmission shaft 300 away from the driving member 100 is connected to the tray 600, and a plurality of second fruit dropping rubber skins 700 are all connected to the tray 600, and the plurality of second fruit dropping rubber skins 700 are arranged around the transmission shaft 300 to form the bottom plate 210 of the fruit dropping tray 200; the second fruit dropping rubber skin 700 at the head end and the second fruit dropping rubber skin 700 at the tail end are arranged at intervals to form the notch 211. The second fruit dropping rubber skin 700 is fan-shaped, and a plurality of second fruit dropping rubber skins 700 are jointly stacked to form a circular or fan-shaped bottom plate 210. Because the material of the second fruit dropping rubber skin 700 is relatively soft, after the fruits and vegetables fall in, the second fruit dropping rubber skin 700 will be pressed and sunken, and it will roll to the notch 211 and then roll onto the first fruit dropping rubber skin 500. When the fruits and vegetables fall onto the first fruit dropping rubber skin 500, it plays the first buffer, and when it falls onto the second fruit dropping rubber skin 700, it plays the second buffer, thereby greatly preventing the fruits and vegetables from being damaged during the boxing process.

[0050] The second fruit dropping rubber skin 700 in this embodiment is a fan-shaped rubber skin, and its total radian angle is 110°, the bottom plate 210 is circular, and the angle of the notch 211 is 65°. Of course, the radian of the second fruit dropping rubber skin 700 can also be other angles, as long as the total radian angle of the second fruit dropping rubber skin 700 is greater than the radian angle, and the specific design of what radian angle is not limited herein. In addition, the bottom plate 210 can also be made of an elastic material into a disc-shaped or other shaped structure to carry fruits and vegetables.

[0051] Please refer to Figure 3 , to prevent the fruits and vegetables from rolling out from the side of the box body, a fruit blocking brush 221 is connected to the side plate 220 in this embodiment.

[0052] To check whether the box is full, a sensor is provided at the bottom of the fruit dropping tray 200 in this embodiment. To improve the accuracy of the sensor detection, a fruit-touching strip brush 800 is provided on the side of the fruit dropping tray 200 away from the driving member 100. The fruit-touching strip brush 800 is electrically connected to the sensor. When the fruits and vegetables in the packing box are stacked to a certain height, the fruit-touching strip brush 800 will touch the fruits and vegetables. When touching a large number of fruits and vegetables, the fruit-touching strip brush 800 will tilt at a certain angle, and the sensor will receive the signal. Then the control system will lift the fruit dropping device 1000 upward and continue to pack the fruits and vegetables until the entire box is full.

[0053] A fruit dropping device 1000 provided according to this embodiment has the following working principle:

[0054] When the fruits and vegetables fall into the disk from one side of the disk, they first land on the fan-shaped rubber of the floating strut 400 and rotate with the fan-shaped rubber. Since the rotation speed of the floating strut 400 is faster than that of the lower disk, when the fan-shaped rubber rotates to the disk notch 211, the fruits and vegetables will press the fan-shaped rubber to form a depression, and the fruit-blocking brush 221 will prevent the fruits and vegetables from rolling out from the side of the disk. After the fan-shaped rubber is pressed by the fruits and vegetables, the rubber in the middle where there are fruits and vegetables will slowly fall and fit with the fruit-dropping rubber. The tail end of the fan-shaped rubber will rotate with the differential speed and slowly land on the first fruit-dropping rubber 500, and the fruits and vegetables will also slide onto the first fruit-dropping rubber 500. Since the fruit-dropping rubber is relatively long, the long rubber can play a certain role in decelerating, and the fruits and vegetables will rotate on the fruits and vegetables in the large box with the first fruit-dropping rubber 500. When at the low-lying area on the surface of the fruits and vegetables in the large box, the fruits and vegetables on the first fruit-dropping rubber 500 will slide into the large box. When the strut 410 and the disk notch 211 clamp the fruits and vegetables, the fruits and vegetables will push up the strut 410 and the fan-shaped rubber until they slide to the first fruit-dropping rubber 500 at the next notch 211, thus avoiding directly shearing and breaking the fruits and vegetables like the fixed strut 410. As more fruits and vegetables are packed into the large box, the fruit-touching strip brush 800 rotating with the disk will touch more fruits and vegetables and tilt at a certain angle. The sensor will be triggered on the fruit-touching strip brush 800, sending a signal to the packing machine to lift upward and continue to pack the fruits and vegetables until the large box is full.

[0055] In summary, the fruit dropping device 1000 includes a driving member 100, a fruit dropping tray 200, a transmission shaft 300, and a floating support rod 400. One end of the transmission shaft 300 is connected to the driving member 100, and the other end of the transmission shaft 300 is connected to the fruit dropping tray 200. The floating support rod 400 is movably connected to the side of the transmission shaft 300 close to the fruit dropping tray 200, and the floating support rod 400 can float back and forth along the axial direction of the transmission shaft 300. By providing the floating support rod 400, the floating support rod 400 is used to push the fruits and vegetables falling into the fruit dropping tray 200 into boxes.
