Description

Technical Field

[0001] This utility model relates to the field of sugarcane juicers, specifically to a sugarcane juicer that can avoid cutting the sugarcane. Background Technology

[0002] Currently, some sugarcane juicers are roller press juicers, which use opposing rotating rollers to draw in sugarcane. The rollers force the sugarcane through the gap between them, flattening it and squeezing out the juice, which drips down. Simultaneously, the rollers pull the sugarcane through the gap. To prevent slippage, the rollers have sharp teeth. However, some sugarcane peels are thin and brittle, often causing the peel and pulp to break during juicing. This results in the dripping juice containing excessive peel and pulp fragments. Furthermore, the sharp teeth can easily cause the sugarcane to break, hindering the pulling of the entire stalk and producing even more debris in the juice. Therefore, existing sugarcane juicers need improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sugarcane juicer that can avoid cutting the sugarcane and reduce the amount of debris in the sugarcane juice.

The front juicer roller and the rear juicer roller are arranged to rotate in the same direction, while the upper juicer roller and the front juicer roller are arranged to rotate in opposite directions. A first slag passage gap is formed between the front juicer roller and the upper juicer roller, and a second slag passage gap is formed between the rear juicer roller and the upper juicer roller. The front juicer roller, the rear juicer roller, and the upper juicer roller are each formed with circumferentially distributed blunt teeth for contacting the sugarcane peel, and the blunt teeth have concentric tooth top surfaces.

[0006] Preferably, the two ends of the concentric tooth top surface are respectively formed with rounded corners.

[0007] Preferably, the blunt tooth is a trapezoidal tooth.

[0008] Preferably, the second slag passage gap is smaller than the first slag passage gap.

[0009] Preferably, the sugarcane juicer of this invention further includes a motor, which drives the juicing roller assembly to operate.

[0010] Compared with the prior art, the advantages of this utility model are: by setting the front juicing roller, the rear juicing roller and the upper juicing roller to form blunt teeth that are circumferentially distributed for contacting the sugarcane peel, and the blunt teeth forming concentric tooth top surfaces, the sugarcane material can be avoided from being cut and the debris in the sugarcane juice can be reduced.

Detailed Implementation

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model relates to a sugarcane juicer that avoids cutting the sugarcane. Figure 1 As shown, it includes a juicing roller assembly, which comprises a front juicing roller 1, a rear juicing roller 2, and an upper juicing roller 3, as... Figure 1 As shown by the dotted arrow, the front juicing roller 1 and the rear juicing roller 2 are arranged to rotate in the same direction, while the upper juicing roller 3 and the front juicing roller 1 are arranged to rotate in opposite directions. In other words, the upper juicing roller 3 and the rear juicing roller 2 are also arranged to rotate in opposite directions. For example, as... Figure 1As shown, the upper pressing roller 3 rotates clockwise, while the front pressing roller 1 and the rear pressing roller 2 rotate counterclockwise. A first slag passage gap 10 is formed between the front pressing roller 1 and the upper pressing roller 3, and a second slag passage gap 20 is formed between the rear pressing roller 2 and the upper pressing roller 3. The front pressing roller 1 and the rear pressing roller 2 are approximately at the same height, while the upper pressing roller 3 is positioned higher than the front pressing roller 1. Furthermore, in the front-to-back direction, the upper pressing roller 3 is approximately located in the middle of the front pressing roller 1 and the upper pressing roller 2. Figure 2 and Figure 3 As shown, the front pressing roller 1, the rear pressing roller 2, and the upper pressing roller 3 are each formed with blunt teeth 101 arranged circumferentially for contacting the sugarcane peel 99. Figure 2 and Figure 3 Taking the front juicing roller 1 as an example, the blunt teeth 101 have concentric tooth top surfaces 1011. In other words, the concentric tooth top surfaces 1011 are part of a cylindrical surface, and the axis of this cylindrical surface coincides with the central axis (i.e., the axis of rotation) of the front juicing roller 1. Therefore, the radius of the concentric tooth top surfaces 1011 is relatively large, approximating a plane. For the rear juicing roller 2, the axis of the cylindrical surface where the concentric tooth top surfaces 1011 of the blunt teeth 101 of the rear juicing roller 2 are located coincides with the central axis (i.e., the axis of rotation) of the rear juicing roller 2. Similarly, the axis of the cylindrical surface where the concentric tooth top surfaces 1011 of the blunt teeth 101 of the upper juicing roller 3 are located coincides with the central axis (i.e., the axis of rotation) of the upper juicing roller 3. The "blunt" in "blunt teeth 101" refers to the thickness of the sugarcane peel 99, which is typically about 1 mm thick. Figure 3 As shown, setting the width "S" of the concentric tooth top surface 1011 to more than 1.5 times the thickness of the sugarcane peel 99 can be understood as "blunt". Therefore, in practical applications, the width "S" of the concentric tooth top surface 1011 can be set to 2 mm to 2.5 mm.

[0020] The working principle of the sugarcane juicer of this utility model is briefly explained below: Figure 1 As shown, the sugarcane juicer has a casing 7, and the juicing roller assembly is located on the upper side of the casing 7. The juicing roller assembly is covered with a protective shell 4. The upper front end of the protective shell 4 has a sugarcane inlet 401, and the rear side of the protective shell 4 has a sugarcane residue outlet 402. When the juicing roller assembly is running, one end of the sugarcane is inserted into the front side of the first residue passage gap 10 through the sugarcane inlet 401. Due to the counterclockwise rotation of the front juicing roller 1 (in... Figure 1(From the visual direction), the upper juicing roller 3 rotates clockwise, so the upper juicing roller 3 and the front juicing roller 1 combine to suck in sugarcane, forcing the sugarcane through the first slag passage gap 10. The sugarcane is flattened, thereby squeezing out the sugarcane juice. The flattened sugarcane becomes sugarcane residue strips, which then reach the rear juicing roller 2. Since the rear juicing roller 2 rotates counterclockwise, it carries the end of the sugarcane residue strips upward, allowing the sugarcane residue strips to enter and pass through the second slag passage gap 20. Afterward, the sugarcane residue strips are output through the sugarcane residue discharge port 402, and the squeezed sugarcane juice flows down into the juice receiving tray 5 on the upper side of the machine casing 7. During the juicing process, such as Figure 5 As shown, the blunt teeth 101 press the sugarcane peel 99 inward, increasing the friction between the sugarcane peel 99 and the juicing roller assembly, thereby preventing the sugarcane from slipping and facilitating stable traction of the sugarcane by the juicing roller assembly. As mentioned above, Figure 5 As shown, due to the relatively large width of the concentric tooth top surface 1011, the blunt teeth 101 eliminate the need for sharp structures. Therefore, when the blunt teeth 101 press down on the sugarcane peel 99, it is less likely to form sharp pits on the peel 99, thus reducing the likelihood of transverse cracking and debris formation. When the sugarcane is flattened, longitudinal cracks appear in the peel 99, allowing the juice to be squeezed out. However, these longitudinal cracks do not easily cause the sugarcane to break. In summary, by forming blunt teeth 101, the juicing rollers can effectively pull the sugarcane while preventing the peel 99 from easily breaking, thus avoiding cutting the sugarcane and reducing debris in the juice. If the peel 99 cracks transversely, combined with the pulling effect of the juicing rollers, it is easy for the sugarcane to be cut. Since the concentric tooth top surface 1011 is part of the aforementioned cylindrical surface, as... Figure 5 As shown, when the blunt tooth 101 presses the sugarcane peel 99 indented, it is easy to form a gently curved pit in the sugarcane peel 99, further preventing the sugarcane peel 99 from cracking laterally.

[0021] Furthermore, such as Figure 3 As shown, the two ends of the concentric tooth top surface 1011 in the circumferential direction are respectively formed with fillets 1012, such as... Figure 5 As shown, this avoids the corners at both ends of the concentric tooth top surface 1011 piercing the sugarcane peel 99.

[0022] Furthermore, such as Figure 3 As shown, the blunt tooth 101 is a trapezoidal tooth. For example, in the direction inward from the radius of the front juicing roller 1, the width of the blunt tooth 101 is gradually increased. That is to say, the width of the tooth root of the blunt tooth 101 is greater than the width "S" of the top surface 1011 of the concentric tooth of the blunt tooth 101, which helps to increase the connection strength between the blunt tooth 101 and the front juicing roller 1. By setting the blunt tooth 101 to be a trapezoidal tooth, the tooth groove between adjacent blunt teeth 101 is an inverted trapezoid, and the opening end of the tooth groove is wider, which helps to make the tooth groove easy to rinse or brush.

[0023] Furthermore, such as Figure 1 and Figure 6 As shown, the second slag passage gap 20 is smaller than the first slag passage gap 10, that is to say Figure 6 The size "Y" is smaller than the size "X", so that the sugarcane bagasse strip formed by the first bagasse gap 10 is further flattened when it passes through the second bagasse gap 20, which is conducive to more fully squeezing out the sugarcane juice. Moreover, the flattening effect of the juicing roller group on the sugarcane is enhanced step by step, which helps to reduce the bursting of sugarcane flesh 98, thus reducing the debris in the sugarcane juice.

[0024] Furthermore, such as Figure 1 and Figure 4 As shown, the sugarcane juicer of this utility model also includes a motor 6, which drives the juicing roller assembly to operate. Specifically, a support plate is installed on the top of the machine housing 7, and the juicing roller assembly is rotatably connected between the left and right support plates via bearings. The motor 6 is located inside the machine housing 7, and a first sprocket 61 is installed on the output shaft of the motor 6. The right end of the shaft of the rear juicing roller 2 extends to the right side of the right support plate. A second sprocket 62 and a first gear 63 are installed on the right end of the shaft of the rear juicing roller 2. The first sprocket 61 and the second sprocket 62 are connected by a chain. The upper juicing roller 3 is connected by a drive system. A second gear 64 is mounted on the right end of the shaft, meshing with a first gear 63. A third gear 65 is mounted on the left end of the shaft, and a fourth gear 66 is mounted on the left end of the shaft, meshing with the third gear 65. This allows the front and rear juicing rollers 1 to rotate in the same direction, and the upper and front juicing rollers 3 to rotate in opposite directions. The juicing roller assembly is driven by a motor 6, which helps save labor. Figure 1 As shown, the sugarcane inlet hole 401 is higher than the first slag passage gap 10, so the sugarcane is lifted up by the sugarcane inlet hole 401, so that the sugarcane is in an inclined shape with the front higher than the back when it is pressed. Thus, the sugarcane is transported to the first slag passage gap 10 by gravity.
