Description

Technical Field

[0001] This application relates to the technical field of potato cutting, and particularly relates to a potato cutting device. Background Art

[0002] Potatoes are one of the important agricultural products in China. They are characterized by high yields and rich nutrition, and are important crops that can be used as food, vegetables, animal feed, and industrial raw materials in China. Currently, there are various processing methods for potatoes. Among them, the sour and spicy potato cubes made from potatoes are one of the commonly eaten snacks.

[0003] For potato cutting processing, there are generally two methods. One is manual cutting, that is, the operator holds a knife to cut the potatoes. However, this cutting processing method has a high manual labor intensity and low cutting efficiency. It is generally applicable to low-yield processing factories or family workshops. At the same time, the sizes of the potato cubes cut by this processing method vary greatly, which is not conducive to achieving standardized production or quantitative packaging. The other is cutting by a cutting machine, that is, using a cutting machine to cut the potatoes. However, since the cutting process of the cutting machine is generally carried out in two stages, that is, first cutting the potatoes into strips and then cutting the strip-shaped potatoes into cubes. At the same time, during the transfer of the strip-shaped potatoes to the cutting position, there will also be a certain degree of rotation or displacement. In this way, there will be many very small pieces in the cut potato cubes (these pieces will be regarded as waste and discarded). Not only is the cutting yield not high, but also the potato waste is relatively serious. Content of the Utility Model

Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0032] In the description of the present application, it should be noted that the terms used, such as "top surface" and "bottom surface", refer to the upper side of the potato cutting device of the present application as the top surface and the lower side as the bottom surface in the use state; the terms used, such as "first" and "second", are only for distinguishing expressions, rather than indicating or implying any difference in importance or order; the terms used, such as "inner" and "outer", refer to the inside and outside of the specific contour. The use of the above terms is only for facilitating a clear and simple description of the technical solutions of the present application and cannot be construed as a limitation to the present application.

[0033] For the convenience of those skilled in the relevant art to understand, the process of cutting potatoes by a cutting machine in the existing related art will be described below first.

[0034] At present, for the slicing machines in the existing related technologies, generally, it includes two processes. That is, first, use a cutting tool to cut potatoes into strips, then transfer the strip-shaped potatoes to the slicing position, and then use another cutting tool to cut the strip-shaped potatoes into pieces. However, during the transfer process of the strip-shaped potatoes, whether it is manual transfer or mechanical transfer, it will inevitably cause a certain degree of rotation or displacement of the position of the strip-shaped potatoes, thus resulting in a large number of very small broken pieces in the cut potatoes. These broken pieces have no processing value and are generally discarded. At the same time, there are still significant differences in the sizes of the potato pieces cut by the existing slicing machines, that is, the slicing yield is not high, which is not conducive to realizing standardized production and quantitative packaging.

[0035] That is to say, when using the existing slicing machine to cut potatoes, there are not only problems with low slicing yield, but also relatively serious problems of potato waste.

[0036] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0037] Embodiment 1

[0038] As Figures 1 to 7 shown, this embodiment provides a potato cutting device 100, which includes a first cutting assembly 1 and a second cutting assembly 2. The first cutting assembly 1 includes a placement tank body 11, a first driving member 12, a pushing block 13 and a first cutting blade 14. The placement tank body 11 includes a bottom wall 111, and a first side wall 112, a second side wall 113, a third side wall 114 and a fourth side wall 115 that enclose the bottom wall 111 and are sequentially connected end to end. The first side wall 112 and the third side wall 114 are oppositely arranged, the second side wall 113 and the fourth side wall 115 are oppositely arranged. A first notch 1121 is formed on the first side wall 112, and a second notch 1141 opposite to the first notch 1121 is formed on the third side wall 114. The included angle between the second side wall 113 and the bottom wall 111 is an obtuse angle. The output end of the first driving member 12 is connected to the pushing block 13. The shape of the pushing block 13 matches the first notch 1121. The first driving member 12 is used to drive the pushing block 13 to move from the first notch 1121 to the second notch 1141. The first cutting blade 14 is installed in the second notch 1141. The first cutting blade 14 is formed to include a plurality of first blade bodies 141 extending in the horizontal direction and a plurality of second blade bodies 142 extending in the vertical direction. The plurality of first blade bodies 141 and the plurality of second blade bodies 142 are perpendicularly connected to jointly form a mesh blade structure with a plurality of equal-sized square holes.

[0039] The second cutting assembly 2 is disposed above the bottom wall 111. The second cutting assembly 2 includes a second driving member 21 and a second cutting blade 22. The output end of the second driving member 21 is connected to the second cutting blade 22 for driving the second cutting blade 22 to move towards the bottom wall 111.

[0040] Through the above technical solution, when the potato cutting device 100 of the present application cuts potatoes, first, the second cutting assembly 2 is used to cut the potatoes located in the placement tank 11 into slices in the vertical direction, and then the second cutting assembly 2 is used to cut the sliced potatoes into blocks. During the entire cutting process, the sliced potatoes are cut into blocks without displacement or rotation. Therefore, potatoes can be cut into potato blocks of relatively uniform size. In this way, compared with the manual cutting method in the related prior art, the potato cutting device 100 of the present application can effectively improve the potato cutting efficiency, and can effectively reduce the labor intensity of workers. Moreover, more importantly, it can effectively ensure the size of the cut potato blocks, which is convenient for realizing standardized production, and is also conducive to quantitative packaging. Compared with the cutting method of the cutting machine in the related prior art, the potato cutting device 100 of the present application can make the sizes of the cut potato blocks tend to be consistent, and the proportion of potato fragments is very small. It can not only effectively improve the yield rate of potato cutting, but also effectively reduce the waste of potatoes.

[0041] The working process / principle of the above embodiment is as follows: When potato cutting operation is required, one or more potatoes can be first slid into the placement tank 11 through the inclined second side wall 113 (to ensure that the sliced potatoes do not tilt or fall, when putting potatoes, ensure that the potatoes are respectively abutted against the first side wall 112, the second side wall 113, the third side wall 114 and the fourth side wall 115). Then the second driving member 21 is started to make the second cutting blade 22 cut the potatoes into slices in the vertical direction, and then the second driving member 21 is controlled to retract the second cutting blade 22 to its original position. At this time, the potatoes will not tilt or fall under the limiting action of the first side wall 112, the second side wall 113, the third side wall 114 and the fourth side wall 115. Subsequently, the first driving member 12 can be started to make the pushing block 13 push the sliced potatoes towards the first cutting blade 14. Since the first cutting blade 14 is a mesh blade structure composed of a plurality of first blade bodies 141 and second blade bodies 142, the first cutting blade 14 will cut the sliced potatoes into blocks and push them out of the placement tank 11.

[0042] So far, a potato cutting operation has been completed. When the next potato cutting operation is required, the first driving member 12 can be started to retract the pushing block 13 to its original position, and then the potatoes to be cut can be placed in the placement tank 11, so that the next potato cutting operation can be carried out.

[0043] In an embodiment of the present application, the included angle β between the second side wall 113 and the bottom wall 111 of the present application may satisfy: 120° ≤ β ≤ 150°. The reason for setting the second side wall 113 to have an obtuse angle with the bottom wall 111 (i.e., the second side wall 113 is set to be inclined) is to facilitate putting potatoes into the placement groove body 11 through the second side wall 113. Therefore, the inclination angle of the second side wall 113 should not be too large or too small. An overly large inclination angle will make it inconvenient for the potatoes to be limited by the second side wall 113, and an overly small inclination angle will make it inconvenient to put the potatoes into the placement groove body 11. After multiple tests and summaries by the inventors of the present application, it is considered that the suitable range of the included angle β between the second side wall 113 and the bottom wall 111 is 120° ≤ β ≤ 150°. In addition, the included angle β equal to 145° can be preferably selected.

[0044] In an embodiment of the present application, as Figure 6 shown, on the side of the pushing block 13 of the present application close to the second notch 1141, a plurality of convex blocks 131 corresponding to the equal-sized square holes one by one may be formed. The first driving member 12 is configured to be able to drive the pushing block 13 to move towards the first cutting blade 14 until at least a part of the convex blocks 131 is inserted into the equal-sized square holes.

[0045] In this way, when the pushing block 13 provided with a plurality of convex blocks 131 pushes the flaky potatoes towards the first cutting blade 14, it can enable the first cutting blade 14 to completely pass through the potatoes, which can not only effectively ensure that the potatoes are completely cut off, but also effectively ensure that all the potatoes can be pushed out of the placement groove body 11, so as to facilitate the subsequent cutting process of the potatoes.

[0046] In an embodiment of the present application, as Figure 7 shown, the second cutting blade 22 of the present application may include a plurality of third blade bodies 221 arranged at intervals and a connecting plate 222. A plurality of third blade bodies 221 all extend in the vertical direction, and one end of a plurality of third blade bodies 221 is connected to the connecting plate 222. The output end of the second driving member 21 is connected to the connecting plate 222.

[0047] In this way, through the second cutting blade 22 arranged in this way, the synchronous slicing of potatoes can be realized under the drive of one second driving member 21, avoiding the potatoes from tipping due to uneven force and ensuring the good rate of cutting. At the same time, the slicing operation of all the potatoes in the placement groove body 11 can also be realized at one time, which can effectively improve the operation efficiency.

[0048] In an embodiment of the present application, the number of the third blade bodies 221 of the present application may be set to 2 to 5.

[0049] Of course, it can be understood that the number of the third blade bodies 221 of the present application can be adjusted according to the size of the placement groove body 11 and the size of the potatoes to be cut specifically. The present application does not make specific limitations thereto.

[0050] In an embodiment of the present application, as Figure 5 shown, a plurality of receiving grooves 1111 corresponding to the third blade bodies 221 one by one are formed on the bottom wall 111 of the present application, and the second driving member 21 is configured to be able to drive the third blade bodies 221 to move towards the bottom wall 111 until at least part of the third blade bodies 221 are inserted into the receiving grooves 1111.

[0051] In this way, during the process of the second cutting assembly 2 slicing the potatoes, at least part of the third blade bodies 221 can be inserted into the receiving grooves 1111, so that it can be ensured that the potatoes are completely cut off, and thus the cutting yield of the potatoes can be effectively guaranteed.

[0052] In an embodiment of the present application, as Figures 1 to 3 shown, the potato cutting device 100 of the present application may further include a housing 3, and the housing 3 covers the first cutting assembly 1 and the second cutting assembly 2. In this way, the first cutting assembly 1 and the second cutting assembly 2 can be covered by the housing 3, which can not only effectively protect the normal working processes of the first cutting assembly 1 and the second cutting assembly 2, but also prevent foreign objects from entering the placement groove body 11 and affecting the quality or cutting efficiency of the potato pieces. In addition, the provided housing 3 can also prevent the operator from directly contacting the first cutting assembly 1 and the second cutting assembly 2, and can effectively improve the operation safety of the operator.

[0053] In an embodiment of the present application, as Figure 3 shown, the potato cutting device 100 of the present application may further include a control unit 4. The control unit 4 is arranged in the housing 3, and the control unit 4 is electrically connected to the first driving member 12 and the second driving member 21 respectively. In this way, the control logics of the first driving member 12 and the second driving member 21 can be preset through the control unit 4 to realize automatic cutting operation and further improve the potato cutting efficiency.

[0054] In an embodiment of the present application, as Figure 2As shown in the figure, the potato cutting device 100 of the present application may further include an operation module 5. The operation module 5 is electrically connected to the control unit 4. The operation module 5 is used to control the first driving member 12 and the second driving member 21 through the control unit 4. Moreover, the operation module 5 is installed on the outer housing 3. In this way, the operator can very conveniently adjust the first driving member 12 and the second driving member 21 through the control unit 4 by means of the operation module 5 provided on the outer housing 3, so that the relevant operation frequencies of the potato cutting device 100 of the present application can be adaptively adjusted.

[0055] In an embodiment of the present application, as Figures 1 to 4 shown, the potato cutting device 100 of the present application may further include a tray 6. The tray 6 is installed on the side surface of the third side wall 114 away from the first side wall 112. Moreover, the tray 6 is located below the second notch 1141. The tray 6 includes a plate body 61 and limiting plates 62 provided on both sides of the plate body 61. The top surface of the plate body 61 includes a first edge 611 and a second edge 612 which are oppositely arranged. The first edge 611 is in contact with or connected to the third side wall 114. In the direction from the first edge 611 to the second edge 612, the height dimension of the top surface gradually decreases.

[0056] In this way, the cut potato pieces, after being pushed out of the placement groove body 11 by the pushing block 13, will fall on the tray 6 and be collected and diverted by the tray 6, thus facilitating the operator to collect or transfer the potato pieces.

[0057] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
