[0001] The utility model relates to the technical field of fruit and vegetable slicing, in particular to an automatic quartering device for vegetable and fruit sampling. Background Art

[0002] In the experiment of sampling and detecting fruits and vegetables, in order to ensure the representativeness and randomness of the sampling results, it is necessary to cut and mix the raw materials evenly. Due to the different sizes and shapes of various test fruits and vegetables, it is extremely difficult for ordinary cutting devices to ensure the uniformity after cutting, and excessive randomness seriously affects the accuracy of the experiment. Therefore, an automatic quartering device for vegetable and fruit sampling is needed to solve the above deficiencies.

[0003] Chinese Patent CN211842133U discloses a multi-functional fruit and vegetable slicing device, including a cutting table. Vertical side plates are arranged at both ends of the cutting table, and a top plate is arranged at the top of the side plates. Strip-shaped through holes are opened on both side plates, and a first slicing device is arranged between the two strip-shaped through holes. Placement tables are arranged on both sides of the cutting table. An extrusion device is placed on one of the placement tables, and a second slicing device is placed on the other placement table. In this solution, the first electric hydraulic cylinder is used to push the pushing block to move, so as to clamp the fruits and vegetables placed on the cutting table and fix the fruits and vegetables on the cutting table. After the blade moves up and down to complete the cutting, the second electric hydraulic cylinder is turned on, and the cross-shaped blade connected to the output end of the second electric hydraulic cylinder slides along the cross-shaped through hole opened on the fixing block to complete the secondary cutting of the fruits and vegetables on the cutting table, achieving the effect of fine slicing of fruits and vegetables.

[0004] The above solution still has several improvement points: slicing fruits and vegetables in two times reduces the slicing efficiency; the blade is easy to contact with the clamping component and cause damage. Summary of the Utility Model

[0005] To solve the problems of the prior art, the utility model provides an automatic quartering device for vegetable and fruit sampling, including a workbench for clamping and dividing fruits and vegetables, a conveying pipeline for feeding materials onto the workbench, and a cross cutter for cutting fruits and vegetables.

Specific embodiments

[0023] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-6 As shown, an automatic quartering device for sampling vegetables and fruits includes a workbench 1 for clamping and classifying fruits and vegetables, a conveying pipeline 5 for feeding materials onto the workbench 1, and a cross cutter 6 for cutting fruits and vegetables. The workbench 1 includes a fixture 2 for clamping fruits and vegetables, a bottom plate 3 that can be opened and closed, and a collection tank 4 for separately packaging the cut fruits and vegetables. The conveying pipeline 5 is vertically installed at the center of the upper surface of the workbench 1, the cross cutter 6 is arranged at the center of the conveying pipeline 5, the fixture 2 is annularly arrayed on the upper surface of the workbench 1 and passes through the pipe wall of the conveying pipeline 5, the bottom plate 3 is arranged at the center of the workbench 1 and is aligned with the conveying pipeline 5, and the collection tank 4 is installed at the center of the lower surface of the workbench 1.

[0025] The device uses a workbench 1 with a switchable bottom plate 3 as a cutting module, mainly for round and block-shaped vegetables and fruits, as well as some strip-shaped vegetables and fruits with larger diameters, such as apples and watermelons. The conveying pipe 5 above the workbench 1 is used as a feeding module, so that raw materials such as vegetables and fruits fall vertically from the conveying pipe 5 onto the workbench 1. The clamp 2 arranged on the workbench 1 passes through the pipe wall of the conveying pipe 5 to clamp the vegetables and fruits vertically. The clamp 2 has the telescopic ability to ensure that the workbench 1 can stably fix vegetables and fruits of different sizes vertically. Then, the cross cutter 6 in the conveying pipe 5 cuts the raw materials into four parts from just above the workbench 1. The cross cutter 6 and the clamp 2 of the workbench 1 are crossed and separated to prevent the clamp 2 from hindering the falling of the cross cutter 6. After the raw material cutting is completed, the bottom plate 3 in the workbench 1 is opened. The opening of the bottom plate 3 will drive the cut vegetables and fruits to be mixed evenly. Then, the cut raw materials enter the collecting trough 4 along the blade of the cross cutter 6. The contour in the collecting trough 4 matches the cross cutter 6, ensuring that the cut raw materials enter different collection points for collection.

[0026] See also Figure 2 and Figure 3 As shown, the clamp 2 includes a telescopic rod 21, a first spring 22 and a clamping ring 23. The bottom of the telescopic rod 21 is installed on the side of the clamp 2 facing the conveying pipe 5, the clamping ring 23 is installed on the top of the telescopic rod 21, and the first spring 22 is surrounded by the outside of the telescopic rod 21.

[0027] The telescopic rod 21 provides telescopic capability for the clamp 2, and the first spring 22 is used to reduce the clamping force provided by the telescopic rod 21 to prevent the telescopic rod 21 from excessively squeezing the clamping ring 23 and causing the vegetables and fruits in the clamping ring 23 to be crushed, thereby affecting the experimental accuracy. At the same time, the diameter of the cut vegetables and fruits needs to be larger than the diameter of the clamping ring 23 to prevent the clamp 2 from being unable to fix the vegetables and fruits.

[0028] See also Figures 2-4 As shown, the base plate 3 includes a unit plate 31, a driven gear 32, a driving gear 33 and a knob 34. The unit plates 31 are arranged in a ring array on the base plate 3, the driven gear 32 is installed below the unit plate 31, the driving gear 33 is installed on the lower surface of the workbench 1 and meshes with the driven gear 32, and the knob 34 is installed at the center of the lower surface of the driving gear 33.

[0029] The driving gear 33 is rotated by the knob 34 to drive the unit plate 31 on the driven gear 32 to rotate, and a height difference is formed between adjacent unit plates 31. When the bottom plate 3 is opened, two adjacent unit plates 31 will overlap. The unit plate 31 rotates to switch the bottom plate 3 between the open and closed states. When cutting fruits and vegetables, the bottom plate 3 is closed to provide support for the fruits and vegetables. When packaging fruits and vegetables, the bottom plate 3 is opened, and the quartered raw materials fall into the collecting tank 4 by gravity.

[0030] See alsoFigure 4 As shown, the unit plate 31 includes an arc groove 311, a rotating column 312 and a rotating rod 313. The arc groove 311 is provided on the surface of the driven gear 32. The rotating column 312 is installed on the lower surface of the bottom plate 3, and the rotating rod 313 is installed on the lower surface of the unit plate 31.

[0031] The rotating column 312 is used as the rotation center of the unit plate 31. The arc groove 311 is used to limit the movement range of the rotating rod 313. When the driven gear 32 is forced to rotate, the arc groove 311 rotates with the driven gear 32, thereby squeezing the rotating rod 313 to rotate and driving the unit plate 31 to rotate around the rotating column 312. At this time, the bottom plate 3 switches between the open and closed states.

[0032] See Figures 2-5 As shown, the collection tank 4 includes a column 41, an inclined platform 42 and a side wall 43. Two side walls 43 are cross-mounted at the center of the collection tank 4. The column 41 is installed at the intersection of the two side walls 43. The inclined platform 42 is installed at the bottom of the side wall 43 and is at the intersection of the two side walls 43.

[0033] Since there will be a gap at the center of the bottom plate 3 when the unit plate 31 closes the bottom plate 3, the column 41 is used to block the gap to avoid uneven distribution of fruits and vegetables in the future. The inclined platform 42 is used to provide guidance for the falling of fruits and vegetables to ensure that they can be discharged from the collection tank 4. The side wall 43 has the same contour as the cross cutter 6 to ensure that the raw materials can fall into the collection tank 4 without being blocked.

[0034] See Figure 1 and Figure 2 As shown, the conveying pipeline 5 includes a feeding groove 51, a through hole 52 and a side hole 53. The feeding groove 51 is inclined and installed on the pipe wall of the conveying pipeline 5. The through hole 52 is provided at the center of the conveying pipeline 5. The side holes 53 are arranged in an array on the bottom pipe wall of the conveying pipeline 5.

[0035] The feeding groove 51 is used to transport uncut fruits and vegetables. The inclined angle ensures that the fruits and vegetables can fall vertically onto the workbench 1. The through hole 52 provides a moving guide for the cross cutter 6 to ensure that the cross cutter 6 can evenly cut the fruits and vegetables. The side holes 53 are used to install the fixture 2 to provide the ability to vertically clamp the fruits and vegetables on the workbench 1.

[0036] See Figures 1-6 As shown, the cross cutter 6 includes a positioning frame 61, side ears 64, a positioning rod 62 and a second spring 63. The positioning frame 61 surrounds the outside of the cross cutter 6. The side ears 64 are installed on both sides of the conveying pipeline 5. The positioning rod 62 is installed in the side ears 64. The second spring 63 surrounds the outside of the positioning rod 62.

[0037] The side ear 64 is used to fix the orientation of the positioning frame 61 to prevent it from coinciding with the fixture 2 and causing the cutting knife 6 to be blocked when it falls. The positioning rod 62 is used to prevent the positioning frame 61 from rotating in the conveying pipe 5 and affecting the cutting accuracy. The second spring 63 provides the reset ability for the cross-cutting knife 6, facilitating continuous cutting work.

[0038] See Figure 6 As shown, the positioning frame 61 includes a threaded hole 611, a pressing plate 612, a pressing rod 613, and a sliding groove 614. The threaded hole 611 is provided at the center of the positioning frame 61. The pressing plate 612 is installed on both sides of the positioning frame 61 and is located in the side ear 64. The pressing rod 613 passes through the side ear 64 and is connected to the pressing plate 612. The sliding groove 614 is provided on the side ear 64.

[0039] The threaded hole 611 is used to facilitate the installation and disassembly of the cross-cutting knife 6, facilitating the maintenance of the cutting edge. The pressing plate 612 is used to press the second spring 63. The up and down movement of the pressing rod 613 in the sliding groove 614 facilitates the falling and resetting of the cross-cutting knife 6.

[0040] The above embodiments only represent one or several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
