Description

Technical Field

[0001] The utility model belongs to the technical field of plant tissue cultivation, in particular to an automatic filling device for a nutrient tube for fresh flowers. Background Art

[0002] Flowers are cultivated by tissue culture, which is a technology that cultures plant organs, tissues, cells and protoplasts in vitro on artificial culture media and causes them to grow, proliferate, differentiate and regenerate plants. In addition to adding culture fluid to the culture bottle during the tissue culture process, culture bottles are also used when transporting flowers or using them for short-term decoration. The culture fluid or nutrient solution contained in the culture bottle can provide nutrition for the plants after they are separated from the body, so as to maximize their survival rate or shelf life.

[0003] At present, the most common method is to fill the nutrient tube manually. When the number of nutrient tubes to be filled is large, it not only increases the labor intensity of the workers, but also reduces the work efficiency. Therefore, it is necessary to develop a device that can automatically fill the nutrient solution into the nutrient tube. Utility Model Content

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] An automatic filling device for a nutrient tube for fresh flowers comprises a chassis, a stepper motor, a divider, a connecting rod mechanism arranged in the chassis, and a turntable, a filling group, a feeding rod group, a feeding tray and a control module arranged outside the chassis. The device is characterized in that one side of the divider is meshedly connected with the stepper motor through a gear group, and the other side is connected with the connecting rod mechanism through a belt transmission method of a belt and a synchronous wheel, and the top of the divider is movably equipped with a turntable; the filling group and the feeding rod group are also movably assembled with the connecting rod mechanism; the control module comprises a display screen and control buttons, and is equipped with a PLC to control the operation of each component.

[0006] Preferably, the connecting rod mechanism includes a side plate, a main connecting rod, a camshaft, a cam, a cam bearing follower and a mounting seat. The main connecting rod is movably assembled on the side plate via a connecting rod shaft and a bearing, and the side plate is connected to the synchronous wheel via a cam with a camshaft. A cam bearing follower is installed on the main connecting rod for movably assembled positioning with the inner groove of the cam.

[0007] Preferably, the ejector rod group includes a secondary connecting rod and a ejector rod vertically fixed on the secondary connecting rod, and the secondary connecting rod is movably assembled on a mounting seat at one end of the main connecting rod through a connecting rod shaft and a bearing.

[0008] Preferably, a filling group is also movably assembled on the mounting seat at the other end of the main connecting rod through the connecting rod shaft and the bearing.

[0009] Preferably, the filling group consists of a lifting plate, a guide shaft, a mounting plate, a water pump, a needle and a pressure plate with a spring and a pressure rod. The lifting plate is fixedly mounted on the mounting seat of the main connecting rod, and a guide shaft is vertically arranged on it. A mounting plate is arranged at the end of the guide shaft, and a needle and a pressure plate with a spring and a pressure rod are inverted on the mounting plate. The needle is connected to the water pump through a hose, and the filling group is also provided with a baffle.

[0010] Preferably, the upper panel of the chassis is provided with a plurality of holes for aligning and fixing the ejecting rod, the guide shaft on the ejecting plate, the connecting piece connecting the turntable and the indexer, and the column for auxiliary installation of the unloading tray.

[0011] Preferably, a plurality of injection holes for inserting nutrient tubes are equidistantly provided on the rotating disk.

[0012] Preferably, the filling group and the ejector rod group should be arranged at the positions of the holes to be injected on the turntable.

[0013] Preferably, the upper panel of the chassis is provided with an infrared detector.

[0014] Preferably, the injection port of the bottle cap of the nutrition tube is designed to be inverted cone shape.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The utility model has a reasonable and efficient structure. It uses a divider to achieve a reasonable volume while driving the work in three directions to the greatest extent to cooperate with each other, and cooperates with the connecting rod mechanism to start the linkage effect, so that the nutrient tube in the turntable can complete the actions of rotation, injection, and ejection and falling into the storage place after injection. Compared with the traditional method, the automation is significantly improved, and the nutrient tubes neatly placed on the material tray can be clamped with a manipulator to realize automatic loading. Subsequently, the empty tubes are continuously rotated to the bottom of the filling group by the turntable to achieve the research and development purpose of reinforcing the bottle cap and automatically injecting the nutrient solution into the nutrient tube. After the injection is completed, the nutrient tube filled with nutrient solution is taken away from the injection position by rotating again, and the nutrient tube filled with nutrient solution is transferred to the unloading position. The nutrient tube injected with nutrient solution can be ejected out of the hole to be injected on the turntable by the ejector rod group. After being ejected, it can also fall into the designated storage place along the guide of the unloading tray. This process is reasonable and intelligent. Even if the manipulator is not used to save costs, the efficiency of the nutrient tube is significantly improved compared with the traditional method by manually inserting the nutrient tube, which can greatly reduce the labor intensity and time cost.

[0017] 2. The nutrition tube of the utility model is designed to cooperate with needle injection, and the injection port of the bottle cap of the nutrition tube is designed to be an inverted cone. The inverted cone design is convenient for the needle to be inserted from top to bottom. When it falls into the storage place or shakes during transportation, its closed design can even prevent the nutrient solution inside from leaking out of this injection port to the greatest extent, so as to ensure the yield rate and cost.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 8 As shown, the utility model is an automatic filling device for a nutrient tube for fresh flowers. The utility model mainly comprises a stepping motor (2), a divider (3), a connecting rod mechanism (4) in a chassis (1), and a turntable (5), a filling group (6), a feeding rod group (7), a feeding tray (8) and a control module (9) arranged outside the chassis (1), wherein the control module (9) comprises a display screen and control buttons, and is equipped with a PLC to control the operation of each component.

[0027] The indexer plays a relatively important role in the utility model. One side of the indexer (3) is meshed with the stepper motor (2) through a gear set (11), and the other side is connected to the connecting rod mechanism (4) through a belt drive method of a synchronous wheel (12). The top of the indexer is movably equipped with a turntable (5). Based on this, a stepper motor (2) is designed to drive the movement of the other two working surfaces, and the connecting rod mechanism (4) is also movably equipped with a filling group (6 ) and the ejector rod group (7), so that the connecting rod mechanism (4) can drive the filling group (6) and the ejector rod group (7) to perform dislocation work. Generally, when the filling group (6) is lowered to allow the needle (64) to be inserted into the nutrition tube (13), the first two nutrition tubes (13) that have completed injection will be ejected from the injection hole (51) by the rising of the ejector rod group (7) based on the movement of the connecting rod mechanism (4), and then fall into the discharge tray (8) and fall to the set storage place.

[0028] It can be further explained that the connecting rod mechanism (4) includes a side plate (40), a main connecting rod (41), a camshaft (42), a cam (43), a cam bearing follower (44) and a mounting seat (45). The main connecting rod (41) is movably assembled on the side plate (40) through a connecting rod shaft and a bearing, and the side plate (40) is connected to the synchronous wheel (12) through a cam (43) with a camshaft (42). A cam bearing follower (44) is installed on the main connecting rod (41) to be movably assembled with the inner groove (430) of the cam (43) for relative positioning. The main connecting rod (41) realizes the set and expected movement mode through the cooperation of the cam bearing follower (44) and the inner groove (430) of the cam (43), that is, the filling group (6) and The staggered operation of the ejector rod group (7) enables alternate injection and blanking to achieve automation. It should be noted that how the filling group (6) injects the nutrient solution into the nutrient tube (13) is described. Specifically, the filling group (6) is composed of a lifting plate (60), a guide shaft (61), a mounting plate (62), a water pump (63), a needle (64) and a pressing plate (67) with a spring (65) and a pressing rod (66). The lifting plate (60) is fixedly mounted on the mounting seat of the main connecting rod (41). The guide shaft (61) is vertically arranged on the lifting plate. The end of the guide shaft (61) is provided with a mounting plate (62). The needle (64) and the pressing plate (67) with a spring (65) and a pressing rod (66) are inverted on the mounting plate (62). The needle (64) is connected to the water pump (63) through a hose. The guide shaft (61) serves to orient and guide the lifting direction and distance, while the water pump (63) is used to draw the nutrient solution to the needle (64) and then inject it into the nutrient tube (13) under pressure. Figure 1It can be seen that the turntable (5) is set to rotate in a clockwise direction. If an empty nutrient tube (13) is inserted in the hole (51) to be injected, the positions it reaches in sequence are: under the pressure plate (67) with the spring (65) and the pressure rod (66), under the needle (64), and finally above the ejector rod (71), that is, in front of the unloading plate (8). Therefore, the function of the pressure plate (67) with the spring (65) and the pressure rod (66) is to ensure that the height of the nutrient tube is consistent with the height in the hole (51) to be injected after the tube is placed manually or by a robot, so as to avoid collision with the needle (64) due to excessive height during rotation. It should be further explained that, due to the thickness of the needle (64), the resistance generated when it is withdrawn after the injection is completed is generally very small, and the nutrition tube (13) loaded with nutrient solution will not be carried away from the injection hole (51) when the filling group (6) rises and resets. However, the present invention still adds a baffle (68) to actually solve the possibility that the nutrition tube (13) may be carried out by the needle (64).

[0029] It can also be described in detail that the ejector rod group (7) includes a secondary connecting rod (70) and a ejector rod (71) vertically fixed on the secondary connecting rod (70), the secondary connecting rod (70) is movably assembled on a mounting seat (45) at one end of the main connecting rod (41) through a connecting rod shaft and a bearing, and the mounting seat (45) at the other end of the main connecting rod (41) is also movably assembled with a filling group (6) through a connecting rod shaft and a bearing. The ejector rod group (7) and the filling group (6) arranged at both ends of the main connecting rod (41) can make stable and regular movements based on the working principle of the connecting rod and the guided and fixed working movement of the cam bearing follower (44) in the inner groove (430), so that the ejector rod group (7) and the filling group (6) can work in an up-and-down staggered manner.

[0030] Regarding the upper panel (10) of the chassis (1), it is provided with a plurality of holes for respectively aligning and fixing the ejector rod (71), the guide shaft (61) on the ejector plate (60), the connector (50) connecting the turntable (5) and the indexer (3), and the column (80) for auxiliary installation of the unloading plate (8). Since the action of the utility model is three-dimensional, the working direction and movement include horizontal linkage and vertical movement, some holes must be provided for corresponding rods, columns, and shafts to communicate and penetrate. In addition, an infrared detector (52) is arranged on the upper panel (10), and its detection direction is the hole (51) to be injected on the turntable (5), so as to avoid the utility model still working when there is no nutrient tube (13) inserted in the hole (51) to be injected, resulting in the needle (64) injecting empty nutrient solution.

[0031] It is worth mentioning that the injection port of the bottle cap of the nutrition tube (13) is designed in an inverted cone shape. The inverted cone design facilitates the insertion of the needle (64) from top to bottom. When the tube falls into a storage place or shakes during transportation, its closed design can prevent the nutrient solution inside from leaking out of the injection port to the greatest extent, or even prevent it from leaking out, so as to ensure the yield rate and cost.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
