Description

Technical Field

[0001] This invention relates to a pitting machine, and more particularly to a fully automatic pitting machine for jujubes. Background Technology

[0002] Red dates are a highly nutritious food. When consuming or processing red dates, the pits need to be removed. Manual pitting is not only inefficient but also increases the workload and intensity for workers. Currently, there are various types of pitting machines publicly available. For example, Chinese invention patent application number 201910183498.2 discloses a fully automatic jujube pitting machine, including a frame with a power drive device. A bevel gear disc is rotatably mounted on the frame, and the bevel gear disc is powered by the power drive device through a grooved wheel mechanism. A rotating disk is located above the bevel gear disc, and several centering sleeves arranged circumferentially are provided between the rotating disk and the bevel gear disc. The power drive device is also connected to a connecting frame through a crank-connecting rod mechanism. A pitting tube and a jujube-pumping rod are vertically fixed on the connecting frame. The pitting tube and jujube-pumping rod are installed circumferentially along the rotating disk, and the distance between them is the same as the distance between two adjacent centering sleeves in the same circumferential direction. A pin is also fixedly mounted on the frame and inserted into the pitting tube. A pit-picking motor is also provided on one side of the pitting tube, and a pit-picking rod is installed on the output shaft of the pit-picking motor. This type of pitting machine has a complex structure, high manufacturing cost, and relatively more complex maintenance. In addition, there are some relatively simple semi-automatic core removal machines. These machines require manual assistance during operation, have low automation, and low core removal efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic date pitting machine. The date pitting machine cleverly uses an elliptical slide to realize the extension and retraction movement of the top pitting rod relative to the rotating support, thereby realizing the action of pitting the date. The structure is relatively simple, the degree of automation is high, and the working efficiency is high, which solves the shortcomings of the above-mentioned prior art.

[0004] The technical solution to the above-mentioned technical problems is: a fully automatic jujube pitting machine, comprising jujube sorting blades, a jujube storage cover, a lower shell, a motor, a transmission shaft driven by the motor, and four pitting components located inside the lower shell. The jujube storage cover and the lower shell are connected, and the transmission shaft passes through the middle of the jujube storage cover and the lower shell, with a gap between the transmission shaft and the jujube storage cover. The transmission shaft and the lower shell are connected by bearings. The jujube sorting blades are installed at the top of the transmission shaft and above the jujube storage cover. The jujube storage cover has two symmetrical jujube inlets, and a jujube separating cover is installed on the bottom surface of the jujube inlets. A rotating bracket is also installed on the transmission shaft between the lower shell and the jujube storage cover. The rotating bracket includes a connecting sleeve and four pitting components evenly distributed and connected to the connecting sleeve. A sliding track is a hollow cuboid with an open lower end and an open side away from the drive shaft. A push rod for opening the jujube-removing cover is provided on the upper end of the sliding track. The pitting assembly includes a guide bearing, a jujube clip, front and rear sliders, and a top pitting rod connected to the front and rear sliders. The lower end of the front and rear sliders is connected to the guide bearing. The jujube clip is mainly composed of a positioning folding plate, a four-bar linkage, and left and right clamping plates. The four-bar linkage has hinge points I, II, III, and IV. The front ends of the two connecting rods at hinge point III are respectively connected to the left and right clamping plates. The positioning folding plate is installed at the side opening of the sliding track. Hinge point III is hinged to the positioning folding plate, and hinge point I is hinged to the top pitting rod through a positioning rod.

[0005] An elliptical groove is provided on the upper surface of the lower housing, the center of which coincides with the center of the drive shaft. The front and rear sliders and the top core rod of the core removal assembly are located in the slide rail of the rotating bracket. The top core rod extends out of the outer side of the positioning folding plate. The guide bearing of the core removal assembly is located in the elliptical groove. A long strip-shaped core removal port is opened on the side of the lower housing near the long axis end of the elliptical groove. A date outlet is opened on the bottom surface of the lower housing near the short axis end of the elliptical groove. The date inlet is located between the date outlet and the long strip-shaped core removal port.

[0006] When the guide bearing is located at the long axis end of the elliptical slide, the top core rod is located between the left and right clamping plates and the left and right clamping plates are in a clamped state. When the guide bearing is located at the short axis end of the elliptical slide, the top core rod is located at the side entrance of the left and right clamping plates and the left and right clamping plates are in an open state.

[0007] The jujube-separating cover includes a cover body and an inclined rod connected to the cover body. The jujube-separating cover is installed on the jujube storage cover via a mounting shaft and a torsion spring. When no external force is applied, the cover body of the jujube-separating cover is located at the jujube inlet. The upper end face of the slide is provided with a push rod for pushing the inclined rod of the jujube-separating cover to open the jujube inlet.

[0008] The jujube leaf blade consists of a sleeve mounted on the drive shaft and four blades evenly distributed and connected to the sleeve.

[0009] The electric motor is connected to the transmission shaft via a worm gear and a worm, and the electric motor is mounted on the bottom end face of the lower housing.

[0010] The four-bar linkage is composed of four links of equal length that are hinged together.

[0011] By adopting the above technical solution, the present invention has the following beneficial effects:

[0012] 1. This invention is a small-scale automatic pitting machine for jujubes, suitable for both commercial and household use. Its structure is relatively simple, and it can automatically pit jujubes during operation, requiring no manual assistance. It boasts a high degree of automation and high work efficiency.

[0013] 2. This invention cleverly utilizes an elliptical groove to achieve the extension and retraction movement of the top pit rod relative to the rotating support, thereby realizing the pitting action of jujubes, resulting in a more reasonable structure.

[0014] 3. It is easy to operate. Simply pour the red dates into the date storage lid. No other manual operation is required.

Detailed Implementation

[0030] Example: A fully automatic date pitting machine, such as Figures 1-13As shown, the device includes a jujube-sorting blade 3, a jujube-storing cover 4, a lower housing 2, a motor 5, a drive shaft 7 driven by the motor, and four pitting components 9 located inside the lower housing. The jujube-storing cover 4 and the lower housing 2 are connected. The drive shaft 7 passes through the middle of the jujube-storing cover and the lower housing, with a gap between the drive shaft and the jujube-storing cover. The drive shaft and the lower housing are connected by bearings. When the drive shaft 7 rotates, the jujube-storing cover 4 and the lower housing 2 do not rotate. The jujube-sorting blade 3 is installed at the top of the drive shaft 7 and is located above the jujube-storing cover 4. The jujube storage cover 4 has two symmetrical jujube inlets 41, each with a certain depth to hold just one jujube. A jujube-separating cover 12 is installed at the bottom of each inlet, allowing for the timed addition of jujubes to the pitting component. A rotating bracket 8 is also installed on the drive shaft between the lower shell and the jujube storage cover 7. A key connection is provided between the rotating bracket 8 and the drive shaft 7, allowing the rotating bracket to rotate relative to the lower shell with the drive shaft. The rotating bracket 8 includes a connecting sleeve 81 and four slide rails 82 evenly distributed on the connecting sleeve. 82 is a hollow cuboid with an open lower end and a side away from the drive shaft. The upper end of the slide 82 is equipped with a push rod 11 for opening the jujube-separating cover. The pitting assembly 9 includes a guide bearing 91, a jujube clip 92, front and rear sliders 93, and a top-pin rod 94 connected to the front and rear sliders. The front and rear sliders 93 and the top-pin rod 94 are integrally connected. The lower end of the front and rear sliders 93 is connected to the guide bearing 91. The jujube clip 92 mainly consists of a positioning folding plate 921, a four-bar linkage 924, and a left clamping piece 9. 22. The right clamping piece 923 constitutes a four-bar linkage 924 with hinge points I 9241, II 9242, III 9243, and IV 9244. The front ends of the two connecting rods at hinge point III 9243 are respectively connected to the left clamping piece 922 and the right clamping piece 923. The positioning plate 921 is installed at the side opening of the slide rail 92 away from the drive shaft. Hinge point III 9243 is hinged to the positioning plate 921, and hinge point I 9241 is hinged to the top core rod 94 through the positioning rod 925. The left clamping piece 922 and the right clamping piece 923 open and close under the drive of the four-bar linkage 924.

[0031] An elliptical groove 22 is provided on the upper surface of the lower housing. The center of the elliptical groove coincides with the center of the drive shaft. The front and rear sliders 93 and the top core rod 94 of the core removal assembly are located within the slide rail 82 of the rotating bracket and can move back and forth within the slide rail 82. The top core rod 94 extends out of the outer side of the positioning folding plate 921. The guide bearing 91 of the core removal assembly is located within the elliptical groove 22 and can move within the elliptical groove 22. During the rotation of the rotating bracket, the top core rod can extend and retract relative to the slide rail of the rotating bracket due to the presence of the elliptical groove. A long strip-shaped core removal port 21 is opened on the side of the lower housing near the long axis end of the elliptical groove, and a date outlet 23 is opened on the bottom surface of the lower housing near the short axis end of the elliptical groove. The date inlet 41 is located between the date outlet 23 and the long strip-shaped core removal port 21.

[0032] When the guide bearing 91 is located at the long shaft end of the elliptical groove 22, the top core rod 94 is located between the left clamping plate 922 and the right clamping plate 923, and the left and right clamping plates are in a clamped state (e.g., Figures 9-11 As shown), when the guide bearing 91 is located at the short shaft end of the elliptical groove 22, the top core rod 94 is located at the side entrance of the left and right clamping plates and the left and right clamping plates are in the open state (as shown). Figures 12-13 (As shown).

[0033] In this embodiment, the jujube-separating cover 12 includes a cover body 121 and an inclined rod 124 connected to the cover body. The jujube-separating cover is mounted on the jujube storage cover via a mounting shaft 122 and a torsion spring 123. When no external force is applied, the cover body 121 of the jujube-separating cover is located at the jujube inlet 41, closing the inlet. The upper end face of the slide rail 82 is provided with a push rod 11 for pushing the inclined rod of the jujube-separating cover to open the jujube inlet 41. During the rotation of the rotating bracket 8, the push rod 11 of the slide rail 82 pushes the inclined rod 124 to move the cover body 121, realizing the timed opening of the jujube-separating cover 12. Jujubes fall from the jujube inlet 41 and are clamped between the left clamping piece 922 and the right clamping piece 923 of the jujube clamp. The cover body 121 of the jujube-separating cover automatically resets and closes the jujube inlet 41 under the force of the torsion spring 123. As an alternative, the jujube-separating cover can also adopt other suitable structures.

[0034] In this embodiment, the leaf blade is composed of a sleeve 31 mounted on the drive shaft and four blades 32 evenly distributed and connected to the sleeve. The motor is connected to the drive shaft 7 via a worm gear 6 and a worm 10, and the motor is mounted on the bottom end face of the lower housing. A support foot 1 is also mounted on the bottom end face of the lower housing. The four-bar linkage is composed of four links of equal length hinged together.

[0035] Working process: The motor 5 drives the transmission shaft 7 to rotate, which in turn drives the jujube-sorting blade 3 and the rotating bracket 8 to rotate together. The jujube-sorting blade 3 pushes the jujubes into the jujube inlet 41. The rotating bracket drives the pitting component 9 to rotate synchronously. When the push rod 11 on the slide rail 82 of the rotating bracket rotates to the position of the jujube-separating cover 12, the push rod pushes the inclined rod 124 of the jujube-separating cover, causing the cover body 121 to move and the jujube inlet to open. At this time, the jujube clamp of the pitting component just rotates to below the jujube inlet 41. The jujubes fall from the jujube inlet into the space between the left clamp 922 and the right clamp 923 of the jujube clamp and are held in place. Then the rotating bracket continues to drive the pitting component from the elliptical slide rail... As the short axis end of groove 22 rotates towards the long axis end, the guide bearing 91 of the pitting assembly, guided by the elliptical groove 22, causes the front and rear sliders 93 to drive the top pit rod 94 to move from the inside to the outside within the slide 82. At the same time, the four-bar linkage 924 of the jujube clamp, driven by the movement of the top pit rod from the inside to the outside, causes the left and right clamping plates to gradually change from the open state to the clamping state. That is, as the rotating bracket 8 drives the pitting assembly 9 to rotate from the short axis end to the long axis end of the elliptical groove 22, the jujube is clamped tighter and tighter. At the same time, the top pit rod 94 pushes the jujube pit out of the jujube from the inside and drops it out of the lower shell from the long strip pitting opening 21. After pitting, the rotating bracket drives the pitting assembly to rotate from the long axis end to the short axis end of the elliptical groove. At this time, the jujube clamp slowly opens, and the pitting rod moves from the outside to the inside of the groove. When it reaches the short axis end of the elliptical groove, the jujube clamp opens to its maximum extent, and the pitted jujube is released from the jujube outlet 23 outside the lower shell. Then, the push rod 11 on the rotating bracket groove 82 rotates to the position of the jujube separating cover 12 and pushes the jujube separating cover to open the jujube inlet 41, and the next jujube falls into the jujube clamp. This process is repeated to pit the next jujube.
