Description

Technical Field

[0001] The invention relates to the technical field of fruit branch separation equipment, in particular to sea buckthorn branch fruit threshing equipment. Background Art

[0002] At room temperature, it is difficult to separate fresh seabuckthorn berries from their branches. Because the berries are small and attached to the branches, they easily break when separated. Therefore, it is impossible to separate the berries at room temperature for further processing. They must be quickly frozen before being separated. Currently, most seabuckthorn berry processing manufacturers use a method called quick freezing followed by beating the frozen branches to break up the branches, leaves, and berries before screening. This method is time-consuming, labor-intensive, and extremely inefficient.

[0003] In the prior art, a drum screen threshing machine is often used to thresh sea buckthorn fruits. A threshing rod is provided inside the drum to drive the sea buckthorn branches to roll in the drum, thereby falling off the sea buckthorn fruits. However, after the sea buckthorn fruits are separated, the small branches and leaves are also separated from the large branches. After separation, some small branches, leaves and dust will be mixed in the sea buckthorn fruits, and there are many impurities, so the separation is not complete. Summary of the Invention

The large branches with sea buckthorn fruits enter the roller mechanism 2 through the upper hopper 5, and the sea buckthorn fruits are fallen off from the large branches through the roller mechanism 2, and then enter the screening mechanism 3. The screening mechanism separates the leaves and dust in the sea buckthorn fruits. The separated sea buckthorn fruits enter the second roller 4 for further separation, and the small branches are separated. The separated sea buckthorn fruits are clean and thorough.

[0027] Preferably, a guide plate 51 is fixedly connected to the bottom of the upper hopper 5 for guiding the sea buckthorn branches into the first roller 22 .

[0028] like Figure 3-Figure 5 As shown, the roller mechanism 2 includes a fixed cylinder 21, a first roller 22 rotatably connected to the fixed cylinder 21, and a conveying shaft 23 arranged in the first roller 22; wherein, the first roller 22 is rotatably connected to the fixed cylinder 21 through a pair of bearings 213, the fixed cylinder 21 is fixedly connected to the base frame 1, and a discharge shell 26 is provided at the bottom of the fixed cylinder 21; a plurality of collision rods 25 are provided on the inner wall of the first roller 22, and the surface of the collision rods 25 is wrapped with a rubber layer to avoid damage to the sea buckthorn fruit, and a plurality of first leakage holes 215 are provided on the surface of the first roller 22, and the first leakage holes 215 are rectangular holes, and the sea buckthorn fruit and the small branches that have not been removed and can be It passes through the first leakage hole, then enters the discharge shell 26, and then falls into the screening mechanism 3; a spiral blade 24 is provided on the surface of the conveying shaft 23, which is used to convey the sea buckthorn branches to the outside of the first roller 22. The sea buckthorn branches enter from one end of the first roller 22 and are discharged from the other end through the rotation of the spiral blade 24; and one end of the conveying shaft 23 is connected to a drive motor 214, which is fixedly mounted on the base frame 1; the roller mechanism 2 also includes a pair of transmission mechanisms, and the two transmission mechanisms are respectively provided at both ends of the first roller 22; when the conveying shaft 23 rotates, the first roller 22 is driven to rotate intermittently back and forth through the transmission mechanism.

[0029] The transmission mechanism includes a planetary carrier 28, an incomplete gear 29, a planetary gear 210 and a ring gear 27; wherein the planetary carrier 28 is fixedly connected to the fixed cylinder 21, the incomplete gear 29 is fixedly mounted on the conveying shaft 23, the planetary gear 210 is rotatably connected to the planetary carrier 28, the ring gear 27 is fixedly mounted on the first roller 22, and the planetary gear 210 is meshed with the incomplete gear 29 and the ring gear 27; a pull rod 211 is fixedly connected to the first roller 22, and a tension spring 212 is fixedly connected between the pull rod 211 and the planetary carrier 28; in specific implementation; Figure 5As shown, when the driving motor 214 drives the conveying shaft 23 to rotate, the conveying shaft 23 rotates and drives the spiral blade 24 to rotate, driving the sea buckthorn branches to be conveyed in the first roller 22. When the conveying shaft 23 rotates, it drives the incomplete gear 29 to rotate clockwise. When the incomplete gear 29 is engaged with the planetary gear 210, it drives the ring gear 27 to rotate, and then drives the first roller 22 to rotate counterclockwise. The tension spring 212 is stretched by the force. When the incomplete gear 29 is separated from the planetary gear 210, the first roller 22 rotates back clockwise quickly under the tension of the tension spring. The collision rod 25 collides with the large sea buckthorn branches, and the sea buckthorn fruits are shaken off the sea buckthorn branches. As the conveying shaft 23 continues to rotate, the incomplete gear 29 is continuously engaged with the planetary gear 210, thereby driving the collision rod 25 to continuously collide with the large sea buckthorn branches, and the sea buckthorn fruits are completely separated from the large sea buckthorn branches. The separated large sea buckthorn branches are pushed out from the end of the first roller 22 by the spiral blades 24; impurities such as sea buckthorn fruits, small branches, leaves and dust enter the discharge shell 26 from the first leakage hole 215, and then fall into the screening mechanism 3 for further screening.

[0030] like Figure 6 As shown, the screening mechanism 3 includes a screening box 31, which is fixedly connected to the base frame 1, and a vibrating screen 32 is provided in the screening box 31. A vibration motor is installed in the screening box 31 to drive the vibrating screen 32 to vibrate, and a discharging channel 33 is provided at the bottom of the screening box 31, and the discharging channel 33 is arranged at the discharging position at the lower end of the vibrating screen 32; an air blowing port 34 is provided on the inner wall of one side of the discharging channel 33, and the fan supplies air to the air blowing port 34 through the air duct, and a waste outlet 35 is provided on the inner wall of the other side of the discharging channel 33, and leaves and dust are blown out from the waste outlet 35; sea buckthorn fruits, leaves, twigs and dust fall on the vibrating screen 32, slide downward under the action of the vibrating screen 32, and fall from the discharging channel 33. During the falling process, the air blowing port 34 blows air to blow the dust and leaves out from the waste outlet 35, and the sea buckthorn fruits and twigs fall from the discharging channel 33 and enter the second drum 4 for further separation.

[0031] like Figure 7 As shown, the inner wall of the second roller 4 is provided with a spiral conveying piece 43 and a plurality of stirring rods 41, and the surface of the second roller 4 is provided with a plurality of second leakage holes 44. The size of the second leakage holes 44 is smaller than the size of the first leakage holes 215. The sea buckthorn fruit can pass through the second leakage holes 44, and the small branches cannot pass through the second leakage holes 44 due to their long length. A discharge hopper 6 is provided under the second roller 4. The sea buckthorn fruit enters the discharge hopper 6 through the second leakage holes 44 and is finally discharged from the discharge hopper 6. A rotating shaft 42 is fixedly connected to the center of the second roller 4. When the rotating shaft 42 rotates, it drives the second roller 4 to rotate. Under the rotation of the second roller 4, the small branches and sea buckthorn fruit are further separated.

[0032] Preferably, the rotating shaft 42 and the conveying shaft 23 are connected by a belt and a pulley transmission, so that the first roller 22 and the second roller 4 rotate synchronously; an inclined material guide trough 7 is provided below the discharge channel 33 for guiding the material into the second roller 4, and the material guide trough 7 is fixedly connected to the base frame 1. The end of the material guide trough 7 is U-shaped and is provided at the feed end of the second roller 4, and the sea buckthorn fruits and small branches slide through the material guide trough 7 into the second roller 4 for separation.

[0033] Working principle: After being frozen, the sea buckthorn fruit branches pass through the upper hopper 5 and enter the first roller 22. The conveying shaft 23 drives the first roller 22 to rotate intermittently during its rotation. The collision rod 25 continuously collides with the large sea buckthorn branches to separate the sea buckthorn fruit from the large branches. The separated branches are discharged from the end of the first roller 22. After separation, the sea buckthorn fruit, small branches that have not been separated from the fruit, leaves and other impurities enter the screening box 31 through the first leakage hole 215, slide down from the lower end of the vibrating screen 32, and the leaves and dust are blown away through the air outlet 34. After being separated from the waste outlet 35, the sea buckthorn fruits and the unremoved small branches enter the guide trough 7 and slide down to the second roller 4. The sea buckthorn fruits and the small branches are further separated by the rotation of the second roller 4. The separated sea buckthorn fruits pass through the second leakage hole 44 and are finally discharged from the discharge hopper 6. In this embodiment, the sea buckthorn fruits are separated by multiple processes including the roller mechanism 2, the screening mechanism 3 and the second roller 4. Large branches, leaves, dust and small branches can be separated out in turn. The separated sea buckthorn fruits have fewer impurities and are separated more cleanly and thoroughly.
