Detailed Description

The invention is further illustrated with reference to the following figures and examples.

Example 1: a jujube beating machine as shown in figure 1 relates to main components: the device comprises a base 1, a universal wheel 2, a support rod 4, a rotating pipe 9, an upper swing rod 11, a lower swing rod 12, a tension spring 10, a traction rope 13, a lifting frame 32, a hopper 16, a motor 17, a centrifugal swinging head 20, a power supply and the like. Wherein, the bottom of base 1 is adorned universal wheel 2 and is realized freely moving function on ground, and push-and-pull rod 3 is installed to base 1 upside, moves through push-and-pull rod 3 control base 1. And a universal wheel brake structure (prior art) is provided to keep the base 1 fixed in place. A supporting rod 4 is vertically fixed on the top surface of the base 1, and the supporting rod 4 can be located in the middle of the base 1 and is usually fixed on one side of the base 1.

The rotating frame is arranged on the supporting rod 4, in the embodiment, the rotating frame shown in fig. 7 comprises a rotating sleeve 5, a rotating pipe 9 and a shaft sleeve 7 which are sleeved on the supporting rod 4, and a stop block or a stop bolt 6 is arranged in the middle of the supporting rod 4, wherein the rotating sleeve 5 is fixedly connected with the rotating pipe 9, a contact surface and sliding fit exist between the rotating sleeve 5 and the shaft sleeve 7, the shaft sleeve 7 (the rotating sleeve 5 without the shaft sleeve 7) is located on the annular stop block or the stop bolt 6, and the outer side of the rotating sleeve 5 is connected with a rotating handle or a rotating hand wheel. Thereby driving the rotating handle or rotating the hand wheel to drive the rotating pipe 9 to rotate clockwise or anticlockwise to realize rotation control.

As shown in fig. 1-3, four supports are sequentially arranged on the outer side wall of the rotating pipe 9 from top to bottom, which are respectively a tension spring 10 fixed shaft seat, an upper support, a lower support and a traction rope 13 end connecting seat. The upper and lower supports are respectively provided with shaft holes and are provided with an upper fixed shaft and a lower fixed shaft, one ends of the upper swing rod 11 and the lower swing rod 12 are respectively hinged with the upper fixed shaft and the lower fixed shaft, and the other ends of the upper swing rod 11 and the lower swing rod 12 are respectively hinged in the upper and lower shaft holes of the lifting frame 32 through the upper movable shaft and the lower movable shaft. Satisfies the following conditions: the upper swing rod 11 and the lower swing rod 12 are parallel and have equal length, so that the distance a between the upper fixed shaft and the lower fixed shaft is equal to the distance a between the upper movable shaft and the lower movable shaft, and a parallelogram four-bar linkage structure is formed. The upper swing link 11 and the lower swing link 12 are always parallel regardless of the swing of the crane 32, so that it can be ensured that the crane 32 is always in the vertical up-and-down motion as shown in fig. 10.

And an inclined tension spring 10 is connected between the rotating pipe 9 and the lifting frame 32, so that the requirements of: the vertical distance h1 between the tension spring fixed shaft 15a and the upper fixed shaft is greater than the vertical distance h2 between the tension spring movable shaft 15b and the upper movable shaft, so that the tension spring 10 is in a traction state of being inclined upward. Meanwhile, a traction rope 13 is fixed at the lower part of the lifting frame 32, and the traction rope 13 overcomes the pulling force of the tension spring 10 after being pulled down to control the height of the lifting frame 32. As shown in fig. 10, the theoretical maximum swing angle of the upper swing link 11 and the lower swing link 12 is 0-180 degrees, i.e. the theoretical height difference of the lifting frame 32 is two times of the swing link length 2 b. Therefore, the lifting frame 32 can have a higher lifting difference in a mode that the tension spring 10 drives the swing rod to lift. And the height range of the lifting frame 32 is related to the length of the swing rod, so that the lifting frame is suitable for date beating and date collecting of date trees with almost any height difference. As can be seen from fig. 10, the tension of the tension spring 10 is less in difference in tension regardless of whether the crane 32 swings to the horizontal position, or is higher or lower than the horizontal position. The length of the tension spring 10 is in a direct proportion relation with the length of the upper swing rod 11, but the actual length difference of the tension spring 10 is only 2 (h 1-h 2), namely the variation amplitude of the tension spring 10 at the highest position and the lowest position is not more than 2 (h 1-h 2). Further, when the lifting frame 32 is positioned at the upper side of the horizontal position, the variation range of the tension spring 10 is more than 0 and less than h1-h2, and when the lifting frame 32 is positioned at the lower side of the horizontal position, the variation range of the tension spring 10 is more than h1-h2 and less than 2 (h 1-h 2). It can be seen that when the lifting frame 32 is located at the upper side and the lower side of the horizontal position, the tension spring 10 has a small variation range, but provides small tension and large tension respectively, so that the tension spring 10 can provide more tension to keep balance under the loading state of the hopper 16. The table box in FIG. 10 is f1 < f2 < fi < fn.
