Figure 7As shown, the sprout box comprises a bottom tray 1 and a top box 2, the top box 2 is a hollow quadrilateral box structure with an open bottom, and the bottom of the top box 2 can be buckled on the top of the bottom tray 1. In the aforementioned knife box assembly 10, the bottom plate 12 and the top plate 11 have a set height, and a containing area is formed at this position, the size of the top box 2 of the sprout box is matched with the size of the containing area and the two straight grooves 13 on the bottom plate 12, specifically, the overall height of the top box 2 is greater than the distance between the bottom plate 12 and the top plate 11, the distance between the two end outer walls of the top box 2 is slightly smaller than the distance between the edges of the two straight grooves 13 away from each other, and the distance between the two end inner walls of the top box 2 is slightly greater than the distance between the edges of the two straight grooves 13 close to each other.

[0031] In application, the bottom tray 1 is used for cultivating sprouts, and a seedling tray is placed at the top end (open end) of the bottom tray 1 during cultivation, the root system of the sprouts is located below the seedling tray (in the bottom tray 1), and the sprout product grows above the seedling tray (above the top surface of the bottom tray 1); the top box 2 is generally a transparent plastic box, which is used as the outer packaging box of the final boxed sprout product, and the whole production process of the sprout product includes the following steps:

[0032] S1, cultivating sprouts in the bottom tray 1, placing the top box 2 on the top surface of the bottom tray 1 after the sprouts grow, and then placing the sprout box on the conveying line 3 and conveying it forward along the conveying line 3. When placing the sprout box, the bottom tray 1 is downwardly contacted with the conveying line 3, and the side edge of the sprout box is substantially parallel to the conveying direction of the conveying line 3.

[0033] S2, when the sprout box moves to the position opposite to the knife box assembly 10 along the conveying line 3, the conveying line 3 stops running or the sprout box is blocked at this position by a stop block.

[0034] S3, adjusting the height of the knife box assembly 10 by the lifting mechanism, so that the knife edge 14 is located at a set root cutting height, which is slightly above the top surface of the bottom tray 1 (close to the top surface of the seedling tray), at this time, the structure of the boxed sprout automatic root cutting device is as shown in Figure 1

[0035] ​S4, the knife box assembly 10 is driven by the horizontal moving mechanism to move towards the conveying line 3, in the process, the knife edge 14 gradually cuts into the through hole from one side to the other side of the lower part of the top box 2, and the side walls of the two ends of the top box 2 enter the two straight grooves 13 through the opening ends of the two straight grooves 13. At the end of the action, the root cutting process of the sprout box is completed, at this time, the sprout root system is retained in the bottom disc 1, and the sprout product is located in the space between the top surface of the knife edge 14 and the closed end of the top box 2. The upper part of the top box 2 (the closed end of the top box 2) is clamped between the bottom plate 12 and the top plate 11, and the bottom part of the top box 2 (the opening end of the top box 2) extends out of the bottom plate 12. It should be noted that a limiting structure is also provided in this step to limit the bottom disc 1, so as to avoid the bottom disc 1 from being pushed when the knife box assembly 10 moves horizontally, thereby ensuring the smooth progress of the cutting process. The limiting structure can be selected from various structure forms such as clamps and limiting stops. The specific structure in the embodiment will be described later.

[0036] S5, the knife box assembly 10 carries the top box 2 to rise a set distance through the lifting mechanism, so that the opening end of the top box 2 is separated from the bottom disc 1. Similarly, a limiting structure is also provided in this process to limit the bottom disc 1, so as to avoid the bottom disc 1 from being taken upward when the knife box assembly 10 rises, thereby ensuring the smooth progress of the separation process. The limiting structure can be selected from various structure forms such as clamps and limiting stops. The specific structure in the embodiment will be described later.

[0037] S6, the bottom disc 1 is conveyed forward through the conveying line 3, so that the position of the bottom disc 1 is staggered with the top box 2 in the conveying direction of the conveying line 3. In the specific implementation, a recycling area is provided beside the conveying line 3, and the bottom disc 1 is directly pushed into the recycling area to leave the conveying line 3 after being conveyed forward.

[0038] S7, the knife box assembly 10 carries the top box 2 to turn over 180° through the turnover mechanism, at this time, the top box 2 is in an opening-upward posture, and the structure of the sprout automatic root cutting device is as shown in Figure 2

[0039] S8, the knife box assembly 10 is driven to retreat by the horizontal moving mechanism, since the opening end of the top box 2 is turned to the upward direction and extends out of the top of the knife box assembly 10 through the above-mentioned root cutting and turnover process, a blocking structure can be arranged to block the extending part of the opening end of the top box 2, and the top box 2 is scraped out of the position between the top plate 11 and the bottom plate 12 when the knife box assembly 10 retreats horizontally.

[0040] S9, the top box 2 falls on the conveying line 3, at this time, the opening of the top box 2 is upward, and the sprout product is contained in the top box 2.

[0041] S10, the top box 2 enters the packaging area with the conveying line 3, and the packaging of the sprout product can be completed by capping or film covering the opening end of the top box 2.

[0042] ​From the above working process, it can be seen that the automatic root cutting device for boxed sprout is arranged on the production line to cooperate with the automatic root cutting operation of the boxed sprout. Compared with the manual root cutting method, the production efficiency is high, the root cutting position is accurate, the labor intensity of the operator is effectively reduced, and the safety hidden danger is eliminated. In addition, through the above process design, after the root cutting is completed, no other transfer link is needed, and the product can be directly packaged after being conveyed by the conveying line 3.

[0043] Further, in the design of the sprout box, a through long hole 4 is formed on one side of the top box 2, and the two ends of the through long hole 4 are arranged close to the inner walls of the two ends of the top box 2. The through long hole 4 penetrates the side of the top box 2, the length of the aforementioned blade 14 is matched with the length of the through long hole 4, and the length of the blade 14 is slightly smaller than the length of the through long hole 4. When the sprout box is placed in the aforementioned step S1, the through long hole 4 is directed towards the direction of the cutter box assembly 10, and after the blade 14 penetrates the through long hole 4 in the aforementioned step S4, the root cutting operation of the sprout is completed. The design of the through long hole 4 avoids the deformation of the top box 2 caused by the extrusion of the blade 14 during the cutting process in step S4, thereby ensuring the final packaging quality. On the other hand, in actual application, the through long hole 4 can be used as a calibration reference, which facilitates the identification of sensors, depth cameras and other elements when setting the cutting height, and ensures the accurate height adjustment position of the cutter box assembly 10 in the aforementioned step S3.

[0044] In specific implementation, as shown in Figure 3 , a vertical plate 31 is further arranged in the boxed sprout automatic root cutting device, the vertical plate 31 is fixedly arranged on the side of the conveying line 3 away from the cutter box assembly 10, and the vertical plate 31 is arranged opposite to the blade 14 to provide a cutting counterforce similar to an anvil in the aforementioned step S4. A blade groove 32 is formed in the vertical plate 31, and the blade groove 32 is matched with the blade 14 during the root cutting process in step S4, thereby avoiding excessive impact on the cutting edge of the blade 14 and protecting the blade 14.

[0045] Further, as shown in Figure 3 , Figure 5As shown, a plurality of positioning mechanisms are also provided, which include a positioning cone 33 and a spring 34. The positioning cone 33 is fixedly arranged on the side of the conveying line 3 away from the knife box assembly 10, and the tip of the positioning cone 33 is arranged towards the knife box assembly 10. The spring 34 is sleeved on the positioning cone 33, one end of the spring 34 extends out of the tip of the positioning cone 33, and the other end of the spring 34 is fixedly connected with the positioning cone 33. The setting height of the positioning cone 33 is located between the conveying line 3 and the knife edge 14, and the positioning cone 33 and the spring 34 are matched with the base plate 1. In implementation, the spring 34 and the positioning cone 33 are fixedly installed at the lower part of the vertical plate 31, and this positioning mechanism is used to realize the function of the limiting structure in the foregoing steps S4 and S5. Specifically, in actual application, the base plate 1 is usually made of foam, plastic or the like. When the root cutting operation is performed according to step S4, the base plate 1 is buckled into a whole with the top box 2, and under the action of the pushing force of the knife edge 14, the base plate 1 is moved away from the knife box assembly 10 towards the conveying line 3. In this process, the side edge of the base plate 1 contacts the end of the spring 34, and then gradually compresses the spring 34 and pierces the positioning cone 33. The counterforce provided by the spring 34 gradually increases during the compression process, and when the counterforce increases to a certain extent, the base plate 1 is limited and blocked, thereby ensuring the smooth progress of the cutting process in step S4. In step S5, the positioning cone 33 pierces into the base plate 1, which directly limits the vertical freedom of the base plate 1, thereby ensuring the smooth progress of the separation process of the base plate 1 and the top box 2. After the base plate 1 and the top box 2 are separated, the base plate 1 is pushed back to the conveying line 3 under the elastic force of the spring 34.

[0046] Further, as shown in Figure 2 、 Figure 3 , a scraping plate 35 is also provided, which is fixedly arranged above the side of the conveying line 3 close to the knife box assembly 10, and the scraping plate 35 is matched with the bottom end of the top box 2. In implementation, the scraping plate 35 is fixedly installed at the top of the vertical plate 31, and the scraping plate 35 is the blocking structure described in the foregoing S8, which is used to hang the top box 2 on the conveying line 3 when the knife box assembly 10 is horizontally moved back. It should be understood that, since the scraping plate 35 is fixedly arranged, the knife box assembly 10 with the top box 2 needs to be lifted to the position close to the scraping plate 35 by the lifting mechanism before the knife box assembly 10 is driven to move back by the horizontal moving mechanism in the foregoing S8.

[0047] In particular implementation, as shown in Figures 1 to 3 、 Figure 6As shown, the aforementioned lifting mechanism comprises a lifting motor 21, a lifting screw rod 22, a support 23 and a sliding seat 24, the transverse moving mechanism selects an electric push rod 25, and the overturning mechanism selects a speed reducer motor 26.

[0048] Specifically, as shown in the figure, Figure 4 The blade 14 has an opening angle of 18°, which can effectively reduce the pressure on the top box 2 material during the cutting operation; a plurality of lightening ventilation holes are formed in the bottom plate 12 to reduce the structural weight and keep the ventilation dry during use, thereby prolonging the service life of the blade 14. The cutter box assembly 10 further comprises two side guards 15, both of which are fixedly connected with the top plate 11 and the bottom plate 14, so that the cutter box assembly 10 has a hollow quadrilateral structure with both ends open, thereby further forming a protection to prevent the top box 2 from falling out of the cutter box assembly 10 during the overturning process in the aforementioned step S7; a plurality of protection slots are formed in the side guards 15, which can reduce the structural weight and also reduce the product packaging abrasion caused by excessive contact between the side guards 15 and the side edges of the top box 2 during the cutting operation.
