detailed description

The utility model will be further described below in conjunction with the accompanying drawings of the description, but the utility model is not limited to the following embodiments.

As shown in FIG. 1 , an automatic separation device for lotus pod shells includes a bracket, and the brackets are respectively provided with a separation mechanism for removing the lotus pod shell and a power mechanism for driving the separation mechanism to work.

Described support comprises upper support plate 11 and lower support plate 12 arranged horizontally up and down, is connected by several pillars 13 between upper support plate and lower support plate, is provided with feeding inlet 14 on the upper support plate, is provided with on the lower support plate Corresponding to the discharge port of the feed port (omitted in the figure).

The separation mechanism is arranged in the bracket, the number of the separation mechanism is at least one, generally two or three (shown as two in the figure), and all the separation mechanisms are arranged along the vertical direction.

Each separation mechanism includes a vertically arranged fixed cutter head 2 and a vertically arranged movable cutter head 3 . Wherein: the fixed cutter head is fixed between the upper support plate and the lower support plate through the vertically arranged support shaft 4, and the number of fixed knives 2-1 in the fixed cutter head is 4-8 pieces; the fixed cutter head is also provided with an opening 21. The shape of the opening is fan-shaped (as shown in Fig. 4 and Fig. 5), and it is aligned with the feed port and the discharge port in the vertical direction to form a separation channel for the vertical movement of raw materials; at the same time, the opening also Facing the moving knife shaft; the moving knife shaft 5 is vertically arranged between the upper support plate and the lower support plate and can rotate around the vertical axis under the drive of the power mechanism (the moving knife shaft and the supporting shaft are arranged parallel to each other), and the moving knife is fixed on On the moving knife shaft and on each moving knife shaft, there are evenly arranged several (less than the fixed knife, usually one less) horizontally arranged moving knives 3-1, and the moving knife of the moving knife shaft spirals around the vertical axis arrangement. In addition, a part of the circumferential surface between adjacent fixed knives (about half of the circumferential surface facing away from the opening) is also fixed with an arc-shaped curved plate 22 for sealing, so as to prevent external dust from entering.

Several fixed knives on the fixed cutter head and several movable knives on the movable cutter head are arranged alternately at intervals; the radius of the movable cutter is suitable for the radius of the fixed cutter; the distance between the movable cutter shaft and the support shaft It is greater than the radius of the fixed knife and less than the sum of the radius of the moving knife and the radius of the fixed knife. Therefore, when the moving knife rotates, its blade horizontally crosses the separation channel formed by the opening of the fixed knife disc, and each moving knife passes through a part of the area between two adjacent fixed knives (the dotted line S in Figure 5 represents the moving The trajectory of the knife in the fixed knife)). The distance between adjacent fixed knives is smaller than the outer diameter of lotus seeds (lotus seeds cannot be embedded in the space between adjacent fixed knives), and the distance between adjacent moving knives is greater than the outer diameter of lotus seeds (lotus seeds can pass between adjacent moving knives , then fall into the discharge port from the opening), because the shape of the lotus seed is approximately ellipsoidal, so the outer diameter of the lotus seed is based on the minor axis length of the ellipsoid (the narrowest position of the lotus seed).

In the two separation mechanisms adjacent up and down, all moving knives are fixed on the same moving knife shaft, and all fixed knives are fixed on the same supporting shaft. A guide groove is also provided between the two separation mechanisms for connecting the upper and lower fixed cutter head openings. The guide groove includes several baffle plates 7 arranged vertically on the surface of the fixed knife and forming a V-shaped angle, and the angle matches the opening of the fixed knife disc; the baffle plates are respectively connected to the edge of the bottom fixed knife disc opening of the upper separation mechanism And the edge of the opening of the top fixed cutter head of the lower separation mechanism, the raw materials processed by the upper separation mechanism can enter the lower separation mechanism through the guide groove for further processing.

The power mechanism includes a motor 61 fixed on the upper support plate, a transmission belt 62 and a transmission wheel 63 that transmit power between the motor and the movable knife shaft.

The working process of the present utility model is as follows:

The motor starts, and the external device grabs a number of lotus pods (no more than 2) and puts them into the feeding port. The lotus pods fall along the separation channel under the action of gravity, and the rotating knife will squeeze and knead the lotus pods in the separation channel. When being squeezed, the lotus pod shell breaks and the lotus seeds are separated from the lotus pod shell. The lotus seeds and the broken lotus pod shell continue to fall along the separation channel, and then enter the separation mechanism below to separate again after passing through the pipeline. The crushed material is discharged from the discharge port.

Finally, it should be noted that what is listed above are only specific embodiments of the present invention. Apparently, the utility model is not limited to the above embodiments, and many modifications (such as adding more stages of separation devices) are also possible. All deformations that a person skilled in the art can derive or associate directly from the content disclosed in the utility model shall be considered as the protection scope of the utility model.
