[0002] Navel orange grading and screening is a series of processing processes carried out after the navel orange is harvested. The purpose is to classify the navel oranges according to size, color, shape, quality and other standards to meet the needs of different markets and consumers. Grading and screening is a very critical step in the commercialization of navel oranges, which directly affects the market value of navel oranges and consumers' purchasing experience.

[0003] In the existing navel orange grading and screening, the navel oranges are usually placed on a feeding frame, and the navel oranges are freely rolled down between the sorting bars, and the navel oranges are graded according to the different gap sizes of the sorting bars. However, since a large number of navel oranges need to be placed for sorting, some navel oranges may be stuck on the sorting bars during sorting. The navel oranges stuck on the sorting bars need to be manually placed back on the feeding frame and re-graded, which affects the efficiency of sorting, is time-consuming, and is relatively inconvenient.

[0004] Therefore, it is necessary to design a navel orange grading and screening device that can vibrate and shake navel oranges so that multiple navel oranges will not be sorted during the sorting process, thereby improving the sorting efficiency and saving manpower and time.

The utility model provides a navel orange grading and screening device which can vibrate and shake the navel oranges, does not require multiple navel oranges to be sorted during the sorting process, improves the efficiency of sorting, and saves manpower and time.

[0006] The technical solution is: a navel orange grading and screening device, including a base, a feed frame, a drop frame, a sorting rod and a vibration mechanism, the upper part of the base is connected to the feed frame, the right part of the base is connected to the drop frame, a plurality of sorting rods are connected in the drop frame, and a vibration mechanism is provided between the base and the drop frame to enable the graded navel oranges to fall evenly.

[0007] Furthermore, the sorting rod is conical.

[0008] Furthermore, a partition is provided in the blanking frame to divide navel oranges of different sizes into zones.

[0009] Furthermore, it also includes a blocking mechanism, which includes a guide rail, a screw rod, a slider and a blocking plate. The front and rear sides of the right part of the base are connected to the guide rails, the screw rods are rotatably connected to the guide rails, the sliders are slidably connected to the guide rails, the sliders are connected to the screw rods by threads, and the blocking plates are connected between the sliders.

[0010] Furthermore, a knob is provided on the screw rod.

[0011] Furthermore, it also includes a vibration mechanism, which includes a motor, a cam frame, a vibration frame, a first telescopic spring, a rotating cam, a support frame, a knocking rod and a second telescopic spring. The front part of the base is connected to the motor, the cam frame is connected to the motor output shaft, the cam frame is rotatably connected to the blanking frame, the upper part of the base is slidably connected to the vibration frame, the vibration frame is in contact with the blanking frame, a plurality of first telescopic springs are connected between the base and the vibration frame, the front part of the blanking frame is rotatably connected to the rotating cam, the front side of the blanking frame is connected to the support frame, the knocking rod is slidably connected to the support frame, the second telescopic spring is connected between the knocking rod and the support frame, the rotating cam is in contact with the knocking rod, and a transmission assembly is connected between the rotating cam and the output shaft of the motor.

[0012] Furthermore, the transmission assembly includes a pulley and a linkage belt. The rear sides of the motor and the rotating cam are both connected with pulleys, and the linkage belt is wound around the pulleys.

[0013] The beneficial effects are as follows: 1. The utility model drives the rotating cam to rotate through a pulley and a linkage belt. At this time, the rotation of the rotating cam will squeeze the knocking rod, and the knocking rod knocks the rotating cam, so that the navel oranges can fall smoothly into the drop frame, avoiding inaccurate grading due to uneven stacking, reducing collisions and damages of the navel oranges during the grading process, and maintaining the integrity and appearance quality of the navel oranges.

[0014] 2. The utility model uses a motor to squeeze the vibration frame to move upward, drive the vibration frame to move upward, and repeat this process, so that the vibration frame moves up and down, and the material feeding frame vibrates, so that the navel oranges are evenly distributed on the material feeding frame, and then the position of the blocking plate is adjusted by turning the knob, so that the navel oranges are graded and screened one by one, thereby avoiding equipment blockage, preventing navel oranges from colliding with each other and causing the navel oranges to be smashed, reducing dependence on manual intervention, and reducing labor costs.

DETAILED DESCRIPTION

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] A navel orange grading and screening device, such as Figure 1-Figure 5 As shown, it includes a base 1, a feed frame 2, a drop frame 3, a sorting rod 4 and a vibration mechanism 6. The upper part of the base 1 is connected to the feed frame 2, and the right part of the base 1 is connected to the drop frame 3. A partition is arranged in the drop frame 3 to divide navel oranges of different sizes. A plurality of sorting rods 4 are connected in the drop frame 3. A vibration mechanism 6 is arranged between the base 1 and the drop frame 3 to make the graded navel oranges fall evenly. The sorting rod 4 is conical.

[0023] like Figure 1 and Figure 3 As shown, a blocking mechanism 5 is also included, which includes a guide rail 51, a screw rod 52, a slider 53 and a blocking plate 54. The front and rear sides of the right part of the base 1 are connected to the guide rails 51, the screw rod 52 is rotatably connected to the guide rails 51, the screw rod 52 is provided with a knob, the guide rails 51 are slidably connected to the sliders 53, the sliders 53 are connected to the screw rod 52 by threads, and the blocking plate 54 is connected between the sliders 53.

[0024] like Figure 1 , Figure 4 and Figure 5As shown, the vibration mechanism 6 includes a motor 61, a cam frame 62, a vibration frame 63, a first telescopic spring 64, a rotating cam 66, a support frame 67, a knocking rod 68 and a second telescopic spring 69. The front part of the base 1 is connected to the motor 61, the cam frame 62 is connected to the output shaft of the motor 61, the cam frame 62 is rotatably connected to the blanking frame 2, the upper part of the base 1 is slidably connected to the vibration frame 63, the vibration frame 63 is in contact with the blanking frame 2, four first telescopic springs 64 are connected between the base 1 and the vibration frame 63, the front part of the blanking frame 3 is rotatably connected to the rotating cam 66, the front side of the blanking frame 3 is connected to the support frame 67, the knocking rod 68 is slidably connected to the support frame 67, the second telescopic spring 69 is connected between the knocking rod 68 and the support frame 67, the rotating cam 66 is in contact with the knocking rod 68, and a transmission assembly 65 is connected between the rotating cam 66 and the output shaft of the motor 61.

[0025] The transmission assembly 65 includes a pulley and a linkage belt. The rear sides of the motor 61 and the rotating cam 66 are both connected with pulleys, and the linkage belt is wound between the pulleys.

[0026] When using the device, firstly, the base 1 is placed in the navel orange grading and screening area, some navel oranges are placed in the feeding frame 2, and the motor 61 is started to drive the cam frame 62 to rotate. The rotation of the cam frame 62 will squeeze the vibration frame 63 to move upward, so that the first telescopic spring 64 is deformed, and the spring is reset to drive the vibration frame 63 to move upward.

During the operation of the motor 61, the rotating cam 66 will be driven to rotate through the pulley and the linkage belt. At this time, the rotation of the rotating cam 66 will squeeze the knocking rod 68, so that the second telescopic spring 69 is squeezed and moves backward. When the support frame 67 is separated from the blanking frame 3, the second telescopic spring 69 is reset, and the knocking rod 68 knocks the rotating cam 66, so that the navel oranges can fall smoothly into the blanking frame 3, avoiding inaccurate grading due to uneven stacking, reducing the collision and damage of the navel oranges during the grading process, and maintaining the integrity and appearance quality of the navel oranges.
