Description

Technical Field

[0001] This invention belongs to the field of vegetable processing machinery technology, specifically relating to a combined device for two-stage decoction of headed vegetables. Background Technology

[0002] Heading vegetables are a type of cruciferous plant, and due to their rich nutritional value, they are very popular with consumers, leading to a rapid increase in market demand. For example... Figure 18 As shown, heading vegetables consist of a main root (A), small flower stalks (B), and flower buds (C). During food preparation, most people remove the main root (core), leaving the small flower stalks and flower buds. Therefore, removing the core from heading vegetables not only meets consumer demand and saves them time, but also facilitates packaging, storage, and transportation, reducing transportation costs.

[0003] Existing head vegetable processing equipment mainly employs a single-step process, which suffers from problems such as incomplete removal of the main root (core), low processing efficiency, and significant raw material waste. Patent application number 201711372965.3 discloses a two-stage conveying automatic cutting and core-removing production line for head vegetables, including a frame, feeding device, conveying device, turning device, guiding device, isolation device, arc-shaped guide plate, cutting device, and arc-shaped cutting blade. This patent uses a single power source to simultaneously achieve the cyclical movement and closed-loop cutting of the hemispherical blade. Since the main root (core) of head vegetables is cylindrical, a single-step process inevitably leads to the accidental cutting of small flower stems, resulting in raw material waste. Based on the above, it is crucial to design a dual-step core-removing processing device for head vegetables that employs a two-step process and reduces raw material waste. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and provide a combined device for two-stage decoction of head vegetables. This device should be able to accurately remove the main rootstock of head vegetables and reduce raw material waste.

[0005] The technical solution of this invention is:

[0006] A combined device for double-stage decoction of head vegetables, characterized in that: the device includes a frame, a primary cutting mechanism for separating the small flower stems of head vegetables, a secondary decoction mechanism for removing the main rootstock of head vegetables, and a conveying mechanism for horizontally transporting head vegetables;

[0007] The primary cutting mechanism includes a motor, a guide rail, several cutters arranged around the guide rail, a first transmission mechanism and a second transmission mechanism for sequentially transmitting motor power to drive the cutters to circulate along the guide rail.

[0008] The secondary core removal mechanism includes a core remover and a lifting cylinder that drives the core remover to move up and down.

[0009] The first transmission mechanism includes a first driving sprocket fixed to the motor shaft, a first driven sprocket fixed to the second right-hand shaft, and a first chain mounted on the first driving sprocket and the first driven sprocket;

[0010] The second transmission mechanism includes a pair of second right sprockets rotatably positioned on the frame via a second right-hand pivot, a pair of second left sprockets rotatably positioned on the frame via a second left-hand pivot, and a second chain mounted on the second right sprockets and the second left sprockets on the same side.

[0011] The guide rail includes two inner guide plates disposed between the second chains on both sides, and each inner guide plate is provided with an annular groove.

[0012] The cutter includes a cutting bracket fixed to a second chain, a cutting link axially slidably positioned on the cutting bracket, a pair of pulleys rotatably positioned at one end of the cutting link and capable of rolling along a groove, and an annular cutter head disposed at the other end of the cutting link.

[0013] The chute includes a descending section, a horizontal section, and an ascending section connected in sequence; the guide rail also includes an outer guide plate, which has a guide groove to guide the movement of the second chain.

[0014] The core remover includes a core remover frame, a core remover cylinder fixed on the core remover frame, a pair of arc-shaped blades that are openably and closably positioned on the core remover frame, and a core remover linkage that transmits power from the core remover cylinder to drive the arc-shaped blades to open and close.

[0015] The piston rod of the lifting cylinder is fixed to the core-removing frame; the core-removing frame can be vertically slidably positioned on the frame; the two ends of the core-removing connecting rod are respectively rotatably hinged to the arc-shaped blade and the piston rod of the core-removing cylinder.

[0016] The secondary core removal mechanism also includes a core discharge plate and a translation cylinder that drives the core discharge plate to move horizontally.

[0017] The conveying mechanism includes a tracked conveyor and several trays on the conveyor belt of the tracked conveyor.

[0018] The frame includes a first frame and a second frame. The primary cutting mechanism is located on the first frame, and the secondary core removal mechanism is located on the second frame. The conveying mechanism passes through the first frame and the second frame, and both the primary cutting mechanism and the secondary core removal mechanism are located above the tracked conveyor.

[0019] The beneficial effects of this invention are:

[0020] 1. The present invention uses a cam-like guide rail, which allows the annular cutter head to move synchronously with the heading vegetables in the horizontal direction and to cut and separate the small flower stems on both sides of the main root (core) in the vertical direction;

[0021] 2. This invention uses a cylinder to drive an arc-shaped blade to open and close, thereby cutting off the main rootstock (core). The structure is simple and easy to control.

[0022] 3. This invention uses a two-step process for core removal. First, the small flower stems on both sides of the main rootstock (core) are separated, and then the main rootstock (core) is removed. This reduces the occurrence of accidental cutting and thus reduces the waste of raw materials. Attached Figure Description

Detailed Implementation

[0047] The technical solution of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] like Figure 1 As shown, a dual-process core removal device for headed vegetables (taking broccoli as an example) includes a frame 1, a primary cutting mechanism 2, a secondary core removal mechanism 3, and a conveying mechanism 4.

[0051] The frame is welded from square tubing. The frame includes a first frame 101 and a second frame 102. Figure 1 As shown, the first frame is set on the right and the second frame is set on the left. The primary cutting mechanism is set on the first frame and the secondary core removal mechanism is set on the second frame. The conveying mechanism passes through the first frame and the second frame, and both the primary cutting mechanism and the secondary core removal mechanism are set above the conveying mechanism.

[0052] like Figure 9As shown, the conveying mechanism horizontally transports headed vegetables from right to left. A primary cutting mechanism first separates (removes) the small flower stalks on both sides of the headed vegetable (core) on the conveying mechanism, and a secondary decoction mechanism then cuts off and removes the main rootstock (core) of the headed vegetable from the conveying mechanism. The conveying mechanism includes a crawler conveyor 401 and several trays 403 mounted on the conveyor belt 402 of the crawler conveyor, with a certain distance maintained between the trays. The inner wall of the tray is curved (suitable for the shape of the headed vegetable buds) to ensure that the headed vegetables can be stably placed upside down in the tray, facilitating subsequent processing.

[0053] The primary cutting mechanism includes a motor (omitted in the figure), a guide rail, a cutter, a first transmission mechanism, and a second transmission mechanism. The motor is fixed to the first frame, and several cutters are arranged around the guide rail. The first and second transmission mechanisms are used to sequentially transmit the motor power to drive the cutters to circulate along the guide rail.

[0054] The first transmission mechanism includes a first driving sprocket 211, a first driven sprocket 212, and a first chain 213. The first driving sprocket is fixed to the motor shaft, the first driven sprocket is fixed to the second right-hand shaft, and the first chain is mounted on the first driving sprocket and the first driven sprocket.

[0055] The second transmission mechanism includes a second right-turning shaft 221, a second left-turning shaft 222, a second right sprocket 223, a second left sprocket 224, and a second chain 225.

[0056] The second right-hand rotating shaft and the second left-hand rotating shaft are rotatably positioned on the first frame via bearings. For example... Figure 2 As shown, the second right sprocket is arranged on the right side of the first frame, the second left sprocket is arranged on the left side of the first frame, a pair of second right sprockets are fixed to the second right sprocket, a pair of second left sprockets are fixed to the second left sprocket, and the second chain is mounted on the second right sprocket and the second left sprocket on the same side.

[0057] The guide rail includes an inner guide plate 231 and an outer guide plate. For example... Figure 6 As shown, two inner guide plates are vertically arranged between the second chains on both sides, as... Figure 8 As shown, the inner guide plate is provided with an annular groove 232. The lower half of the groove includes an inclined descending section 261 and an ascending section 263, as well as a horizontal section 262 connecting the descending section and the ascending section. The horizontal section is the lowest point of the groove.

[0058] The outer guide plate is disposed outside the two inner guide plates. Each outer guide plate includes an upper guide plate 251 and a lower guide plate 252. The upper guide plate is provided with an upper guide groove 253, and the lower guide plate is provided with a lower guide groove 254. Figure 7As shown, when the second chain moves clockwise, it passes through the upper guide groove from left to right and the lower guide groove from right to left. The upper and lower guide grooves ensure that the second chain moves stably and prevent the cutter from shaking.

[0059] like Figure 2 As shown, the second chain moves along the following path: first, it goes around the second left sprocket, then horizontally through the upper guide groove from left to right, then around the second right sprocket, then horizontally through the lower guide groove from right to left, and finally returns to the second left sprocket. Figure 7 As shown, the second chain is arranged around the inner guide plate, and the outline of the second chain is larger than the outline of the groove.

[0060] The cutter includes a cutting bracket 241, a cutting connecting rod 242, pulleys 243, and an annular cutter head 244. The cutting bracket is fixed to the links of the second chains on both sides. The cutting connecting rod is axially slidably positioned on the cutting bracket. A pair of pulleys 243 are rotatably positioned at the upper end of the cutting connecting rod. The pulleys can roll along the sliding grooves on both sides. An annular cutter head is provided at the lower end of the cutting connecting rod.

[0061] The annular cutter head is fixed to the cutting link via several L-shaped connecting rods 245. The annular cutter head and the L-shaped connecting rods are integrated, and the L-shaped connecting rods are connected to the cutting link via bolts. The cutting edge angle of the annular cutter head is 8°, and the material is 2Cr13.

[0062] like Figure 9 As shown, the cutter moves clockwise. When the cutter's pulley enters the lower half of the chute, the cutter maintains a vertical posture and moves horizontally from right to left. The speed of the cutter's horizontal movement is the same as the speed of the conveyor belt. When the pulley enters the descending section, as the distance between the descending section and the lower half of the second chain gradually decreases, the cutting rod extends downward, the annular cutter head moves downward, and the annular cutter head encircles the main root of the heading vegetable (…). Figure 19 ), thereby cutting off the small flower stalks on both sides of the main rootstock ( Figure 20 As the pulley enters the ascending section, the distance between the ascending section and the lower half of the second chain gradually increases, causing the cutting linkage to retract upwards, the annular cutter head to move upwards, and the annular cutter head to detach from the main root of the headed vegetable. The horizontal section acts as a buffer, preventing drastic changes in the cutter's movement.

[0063] The secondary core removal mechanism includes a core remover, a lifting cylinder 301, a core removal plate 321, and a translation cylinder 322. The lifting cylinder is used to drive the core remover to move up and down. The lifting cylinder is fixed to the second frame, and the core remover can be vertically slidably positioned on the second frame. The piston rod of the lifting cylinder is fixed to the core remover.

[0064] The core remover includes a core remover frame 311, a core remover cylinder 312, an arc-shaped blade 313, and a core remover connecting rod 314.

[0065] The second frame is provided with vertically arranged sliding columns 103. The core-removing frame can slide vertically along the sliding columns. The piston rod of the lifting cylinder is fixed to the core-removing frame, and the core-removing cylinder is fixed to the core-removing frame. A pair of arc-shaped blades are rotatably positioned on the core-removing frame. A connecting frame 315 is provided on the piston rod of the core-removing cylinder. The two ends of the core-removing connecting rod are rotatably hinged to the connecting frame and the arc-shaped blades, respectively. Both ends of the arc-shaped blades are rotatably positioned on the two side support plates 316 of the core-removing frame. When the piston rod of the core-removing cylinder extends, the arc-shaped blades close. Figure 17 As shown), the curved blade is shaped like a grabber. When it closes, the curved blade performs cutting and grabbing functions. When the piston rod of the core-removing cylinder retracts, the curved blade opens. Figure 16 (As shown). The core removal plate is located below the core remover, and the translation cylinder is fixed to the second frame and used to drive the core removal plate to move horizontally.

[0066] The curved blade has a cutting angle of 15° and is made of 2Cr13 material. The second frame is also equipped with a position sensor 331 for detecting the tray (heading vegetables).

[0067] The present invention also includes a controller (omitted in the figure), which is electrically connected to the conveyor, motor, lifting cylinder, core-removing cylinder, translation cylinder, and position sensor. The controller, conveyor, motor, lifting cylinder, core-removing cylinder, translation cylinder, and position sensor of the present invention are all prior art and can be purchased externally.

[0068] The working principle of this invention is as follows:

[0069] 1. The external device places the heading vegetables one by one into the tray; the heading vegetables are placed upside down on the tray, with the flower buds facing down and the main root (core) facing up;

[0070] 2. For example Figure 9 As shown, the tracked conveyor drives the headed vegetables to move horizontally from right to left (the conveyor belt of the tracked conveyor rotates counterclockwise);

[0071] 3. The cutter along Figure 9 The cutter rotates clockwise; the cutter and the tray containing the headed vegetables move horizontally from right to left in sync, with the tray positioned directly below the cutter and moving horizontally simultaneously. The ring-shaped blade performs one downward and upward movement during the movement, cutting off the small flower stalks on both sides of the main root (core). Figure 20 The cut flower stems fall onto the conveyor belt and are collected separately.

[0072] 4. When the position sensor detects the tray, the tray is directly below the core remover. The secondary core removal mechanism is activated, and the conveyor belt and primary cutting mechanism are paused. The lifting cylinder is activated, driving the core remover downwards. The core removal cylinder is activated, the arc-shaped blades close, cutting off and grasping the main rootstock (core). Figure 21 The dotted line in the diagram represents the cutting trajectory; the lifting cylinder is activated, driving the core remover to move upward and remove the main rootstock (core);

[0073] 5. The crawler conveyor and the first-stage cutting mechanism start; at the same time, the translation cylinder starts, and the core-discharging plate moves to below the core-removing device; the core-removing cylinder starts, the arc-shaped blade opens, and the main root (core) falls onto the core-discharging plate and is discharged to the side for separate collection; the translation cylinder resets.

[0074] 6. Return to step 2, and the present invention will be repeated in the same manner as described above.

[0075] like Figure 23 As shown, in the prior art (201711372965.3 A two-stage conveyor type automatic broccoli cutting and decoring production line), a single-process trajectory is formed by two hemispherical blades rotating around a fixed hinge point. Figure 23 The dotted line (as shown in the original text) covers part of the small flower stems, thus leading to accidental cutting. The two-step process in this invention reduces the possibility of accidental cutting by first separating the small flower stems on both sides of the main rootstock and then cutting off the main rootstock.

[0076] The accompanying drawings illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
