[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0018] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the core removal machine. Figure 2 This is another perspective on the overall structure of the coreless machine. Figure 3 This is a schematic diagram of the installation structure of the push rod.

[0019] This utility model provides a pitting machine, including a base plate 101 and a pitting assembly 102. The pitting assembly 102 includes a bracket 103, a sleeve 104, a lifting seat 105, a connecting seat 106, a connecting screw 107, a top rod 108, a driving component 109, a placement seat 110, and a guide plate 113. The driving component 109 includes a rotating plate 111 and a connecting rod 112, and also includes a return spring 114. The driving component 109 drives the lifting seat 105 to descend, and the lifting seat 105 drives the connecting seat 106, the connecting screw 107, and the top rod 108 to descend, so that the top rod 108 can push out the pit. By replacing the top rod 108 with different sizes, it is convenient to perform pitting operations on different types of fruits. It can be understood that the above solution can be used to facilitate pitting operations on fruits of different sizes, and can also be used to drive the lifting seat 105 to rise and fall.
[0020] In this specific embodiment, the base plate 101 is used to stably place the device on a flat surface such as a desktop.
[0021] The bracket 103 is fixedly connected to the base plate 101 and located on one side of the base plate 101. The sleeve 104 is fixedly connected to the bracket 103 and is disposed on the bracket 103. The lifting seat 105 is slidably connected to the sleeve 104 and is located inside the sleeve 104. The connecting seat 106 is fixedly connected to the lifting seat 105 and is disposed on the lifting seat 105. The connecting screw 107 is threadedly connected to the connecting seat 106. The top rod 108 is fixedly connected to the connecting screw 107. The driving component 109 is disposed on the bracket 103 and is used to drive the lifting seat 105 to move up and down. The lifting seat 105 can move vertically up and down along the sleeve 104.
[0022] In use, the fruit to be pitted is placed on the base plate 101, with the fruit positioned below the top rod 108, so that the top rod 108 is located at the center of the fruit's pit. At this time, the driving component 109 drives the lifting seat 105 to descend, causing the lifting seat 105 to drive the connecting screw 107 and the top rod 108 to descend. The top rod 108 pushes out the pit from the center of the fruit, completing the pitting operation. At the same time, the top rod 108 is connected to the connecting seat 106 through the connecting screw 107, which facilitates the disassembly of the top rod 108 and makes it easy to replace the top rod 108 with one of different diameters. This makes it convenient to pit different types of fruit, and the device is simple, easy to operate and maintain.
[0023] Secondly, the placement seat 110 is fixedly connected to the base plate 101 and is located on the side of the base plate 101 close to the bracket 103; the top of the placement seat 110 is an arc surface and is provided with a through hole 115; the concave surface of the top of the placement seat 110 facilitates the stable placement of the fruit on the placement seat 110, and the through hole 115 allows the top rod 108 to pass through, thereby allowing the top rod 108 to push out the fruit pit.
[0024] Meanwhile, the rotating plate 111 is rotatably connected to the bracket 103 and located on one side of the bracket 103; the connecting rod 112 is fixedly connected to the lifting seat 105 and slidably connected to the sleeve 104, and also slidably connected to the rotating plate 111; the sleeve 104 has a vertical groove 117 on its side that cooperates with the connecting rod 112, allowing the connecting rod 112 to move up and down along the vertical groove 117; the rotating plate 111 has a sliding groove 118, allowing the connecting rod 112 to slide within the sliding groove 118; and a pressing device is also installed on the rotating plate 111. Plate 119 is used to increase the contact area between the rotating plate 111 and the operator's hand, thereby facilitating the pressing of the rotating plate 111. When the user presses the rotating plate 111, the rotating plate 111 rotates around its rotational connection point with the bracket 103. Under the constraint of the sliding groove 118, the connecting rod 112 in the sliding groove 118 moves vertically downward along the vertical groove 117 on the side of the sleeve 104, thereby driving the lifting seat 105, the connecting seat 106, the connecting screw 107 and the top rod 108 to descend synchronously, realizing the pitting operation of the fruit.
[0025] In addition, the guide plate 113 is fixedly connected to the sleeve 104 and is disposed on the sleeve 104; the guide plate 113 is provided with a guide hole 116, which is coaxially disposed with the through hole 115 on the placement seat 110. When the top rod 108 descends, the guide hole 116 of the guide plate 113 can further guide the top rod 108, ensuring that the top rod 108 moves vertically downward and accurately aligns with the fruit pit, effectively preventing the top rod 108 from deviating during the descent, and improving the accuracy and stability of pitting.
[0026] Finally, the two ends of the return spring 114 are connected to the guide plate 113 and the connecting seat 106 respectively, and the return spring 114 is located inside the sleeve 104. When the user releases the pressing plate 119, the return spring 114 releases elastic potential energy, pushing the lifting seat 105 to move upward along the sleeve 104, causing the connecting rod 112 to slide in the groove 118 of the rotating plate 111, so that the rotating plate 111 rotates in the opposite direction and returns to the initial position, preparing for the next core removal operation, simplifying the operation process and improving the core removal efficiency.
[0027] When using the pitting machine of this utility model, firstly, select a top rod 108 with an appropriate diameter according to the type and size of the fruit to be pitted. Loosen the connecting screw 107 to remove the original top rod 108 from the connecting seat 106, replace it with a new top rod 108, and tighten it securely. Then, place the fruit to be pitted into the arc-shaped groove at the top of the placement seat 110. The operator presses the pressing plate 119, and the rotating plate 111 rotates around the rotating connection point with the bracket 103. Under the dual constraint of the sliding groove 118 of the rotating plate 111 and the vertical groove 117 of the sleeve 104, the connecting rod 112 drives the lifting seat 105, the connecting seat 106, and the connecting screw... Rod 107 and top rod 108 descend vertically in sync. When top rod 108 passes through guide hole 116 of guide plate 113, it is vertically aligned with the pit and pressure is applied under the guidance of guide hole 116 to push the pit out of the fruit. After completing one pitting operation, the operator releases the pressing plate 119, and the reset spring 114 immediately releases elastic potential energy, pushing the connecting seat 106 and lifting seat 105 to move upward, causing the connecting rod 112 to slide in the slide groove 118 of rotating plate 111, so that rotating plate 111 rotates in the opposite direction to reset, which facilitates the pitting operation of the next fruit, thereby achieving the purpose of convenient pitting operation for different types of fruit.
