[0059] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0062] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0063] It should be noted that the methods used in the present application are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0064] The present embodiment provides a magazine type automatic seed changing device, as shown in Figure 1 , which mainly comprises a seed box, a seed magazine, a seed magazine conveying mechanism, an empty magazine recycling mechanism and a seed box push-pull mechanism.

[0065] Among them, as the mounting body of each component, the present embodiment is also provided with a first mounting table 1 and a second mounting table 2.

[0066] As shown in Figures 2-4 , the main body of the first mounting table 1 is a box structure 101, and the hollow cavity inside is used as a working cavity. An elevated boss 1011 is arranged in the working cavity, and the upper surface thereof is used as the working position of the seed box push-pull mechanism. The front side of the top surface of the boss 1011 is machined to form an opening and a funnel-shaped seed dropping port 1012 is installed therein. The lower part of the seed dropping port 1012 is connected with a seed dropping channel 106, and the seed dropping channel 106 is connected with the seed inlet of the seed dispenser 4. The rear side of the top surface of the boss 1011 is machined to form an opening, which is used as an empty magazine recycling port. Since the empty magazine recycling of the present embodiment is designed as a constrained falling design, a seed box channel 102 is installed vertically at the empty magazine recycling port, which is used to guide the falling of the seed box to the empty magazine recycling area. A guide structure of the seed box is also arranged between the seed dropping port 1012 and the empty magazine recycling port, which is specifically a slide composed of two upper convex arc edges 1013.

[0067] As shown in Figure 3 , Figure 5 and Figure 6 , the seed magazine 3 is a magazine type structure, which is in an inverted state when in the working position Figure 5The seed box 5 is placed in the seed magazine 3 in a stacked manner. The seed box 5 has a combined structure and includes an inner box body 502 and an outer box body 501. The outer box body 501 is a square box body structure with open ends, and a slide groove with a closed end is formed on the inner side of the two walls. Figure 3 The end of the seed box 5 is the outlet of the seed box 5, and the first bullet holding port 303 is designed. Unlike the open design of the conventional bullet holding port, the semi-open design is adopted in this embodiment, specifically, the end of the two side convex edges is provided with an inwardly curved arc edge, and the upper edges of the two arc edges are connected by a cross beam on the end face, thereby forming a frame-like structure, so as to block the seed box from being pushed out from the front side of the bullet holding port, and still can be pulled out from the rear side.

[0068] Optionally, as shown in Figure 6 , Figure 8 The seed box 5 is placed in the seed magazine 3 in a stacked manner. The seed box 5 has a combined structure and includes an inner box body 502 and an outer box body 501. The outer box body 501 is a square box body structure with open ends, and a slide groove with a closed end is formed on the inner side of the two walls.

[0069] The inner box body 502 is an open box body structure, and the inside is a seed storage compartment 5021, and the opening is used as a seed outlet. The two sides of the inner box body 502 are provided with slide rails 5022, and the inner box body 502 is inserted into the outer box body 501 to be connected in a sliding manner, thereby forming a drawer type structure. Since the slide groove of the outer box body 501 is a structure with a closed end, a limiting structure for sliding of the inner box body 502 is formed, so that the inner box body 502 can only slide out from one side.

[0070] In particular, as shown in Figure 3 and Figure 6 , through the design of the structure size, when the inner box body 502 is pushed out to the specified position, the seed outlet is connected with the seed falling port 1012, the seeds stored in the inner box body 502 fall into the seed falling port 1012, and finally fall into the seed metering device 4; when the inner box body 502 is pulled back, the inner box body 502 moves to the limiting structure, drives the outer box body 501 to exit from the rear side of the first bullet holding port 303 of the seed magazine 3, and moves to above the empty box recycling port.

[0071] Optionally, in order to realize the same limiting effect and guiding effect as the first bullet holding port 303, the second bullet holding port 1021 with the same structure is arranged on the upper end of the seed box channel 102, as shown in Figure 4 , which can prevent the seed box 5 from moving backward horizontally and stop above the empty box recycling port.

[0072] As shown in Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the box push-pull mechanism of the embodiment is a rotary telescopic cylinder 104, and the end of the piston rod 107 of the cylinder is provided with a box connecting assembly for pushing and pulling the seed box 5. The box connecting assembly is a cross shaft perpendicular to the piston rod 107. Further, in order to realize quick connection and quick disconnection with the seed box 5, a semi-closed connecting bin is correspondingly provided at the tail end of the inner box body 502, such as Figures 9-13 As shown, the connecting bin is further divided into a first connecting bin 5023 and a second connecting bin 5024 which are in communication with each other along the axial direction of the piston rod 107.

[0073] The first connecting bin 5023 is provided with a cross-shaped opening 50231 which is in communication with the outside, and a cross-shaped sink 50232 is processed inside the cross-shaped opening 50231, and the cross-shaped opening 50231 and the cross-shaped sink 50232 are axially rotationally misaligned, with a rotation angle of 45°. The second connecting bin 5024 is a circular sink structure. As shown, Figure 10 and Figure 12 As shown, the first connecting bin 5023 is a cross-shaped structure in communication with the second connecting bin 5024 when viewed from the outside, and is a part of a rice-shaped structure in communication with the outside when viewed from the inside. This design can make the cross shaft of the seed box push-pull mechanism enter the second connecting bin 5024 through the cross-shaped opening 50231 when it is pushed forward, and push the inner box body 502 forward to the seed dropping port 1012 through the abutting action; when it needs to be pulled backward, the rotary telescopic cylinder 104 controls the cross shaft to rotate 45° in the second connecting bin 5024, and then pull it backward to the cross-shaped sink 50232, so as to drive the inner box body 502 to retreat, and then drive the outer box body 501 to exit the seed box 3 until the second elastic holding port 1021; finally, when the empty seed box 5 is clamped in the second elastic holding port 1021, the cross shaft is controlled to advance into the second connecting bin 5024, and rotate 45° against the cross-shaped opening 50231, and then the cross shaft is withdrawn, and the seed box 5 falls into the empty box recycling port under the influence of gravity. Optionally, in order to ensure that the seed box 5 does not change its posture under the influence of gravity in a series of withdrawal actions, thereby affecting the subsequent actions, the two convex edges of the second elastic holding port 1021 can be designed to be in interference fit with the outer wall of the seed box 5, so as to prevent the seed box 5 from moving. Further, since the interference fit affects the falling of the seed box 5, at least one electrically driven vibration unit can be fixed on the two convex edges of the second elastic holding port 1021 or the seed box channel 102, which can be a piezoelectric ceramic vibrator 1022, to ensure smooth falling of the seed box 5. Figure 14 As shown,

[0074] The second mounting platform 2 is used for mounting the seed box conveying mechanism and the empty box recycling mechanism, and the outlet of the seed box conveying mechanism is in communication with the working position of the seed box push-pull mechanism, and the working position of the seed box push-pull mechanism is in communication with the inlet of the empty box recycling mechanism.

[0075] Optionally, as shown, Figure 1, Figure 15 and Figure 16 As shown, the main body of the second mounting platform 2 is a side baffle 202 with a clamp-type design, and a transverse continuous slide 203 is provided on the inner side of the side baffle 202. The continuous slide 203 serves as the hanging structure for the seed box 3. The base 301 of the seed box 3 is inserted into the continuous slide 203 on both sides to form a fixed-path conveying structure. A seed box conveying mechanism is provided at one end of the continuous slide 203, and an empty box recycling mechanism is provided at the other end.

[0076] The seed box conveying mechanism is a linear motion mechanism, such as the first linear motor 201, whose push rod end is equipped with a large-area disc, which is used to push a row of seed boxes 3 forward along the continuous slide 203.

[0077] Because the seed box 3 requires sufficient space on its front and rear sides for the movement of the seed box 5 when in the working position, a drop opening 206 is provided on the continuous slide. This opening is a recessed section at the lower edge of the slide, slightly larger than the side length of the base 301, ensuring that the area below the drop opening 206 is the working position of the seed box push-pull mechanism. Thus, when a row of seed boxes 3 passes the drop opening 206 along the continuous slide 203, they will fall sequentially to the working position of the seed box push-pull mechanism. In general designs, to simplify the structure, the sides of the drop opening 206 are designed as ramps, allowing the replacement of the seed box 3 with an empty box to be completed by pushing with the next seed box 3. However, in this embodiment, considering the stability requirements for the seed box 3 entering the working position, the drop opening 206 is designed with square edges, and as shown... Figure 1 and Figure 2 As shown, clamping plates 103 are added to the box structure 101 to stabilize the falling trajectory of the seed box 3. Furthermore, after all the seed boxes 5 in the seed box 3 are retrieved, it becomes an empty box. To send it back to the upper edge of the continuous slide 203, a reciprocating drive mechanism 105 is provided on the side of the dropping opening 206, i.e., installed at the front position on the upper surface of the box structure 101. In this embodiment, the reciprocating drive mechanism is detachably connected to the seed box and is used to drive the lifting and lowering movement of the seed box. Specifically, the reciprocating drive mechanism 105 includes a motor and a gear set, and a vertically installed rack 304 is provided on the front side of each seed box 3. The gear set is connected to the motor. When the rack 304 falls to the bottom with the seed box 3, it engages with the gear set, and the motor drives the rack 104 to continue moving downwards to the designated position through gear meshing. When it is necessary to remove the empty box, the motor reverses to move the empty box upwards. Furthermore, since the rack 304 cannot cover the bottom of the seed box 3, this embodiment also includes an elastic reset mechanism between the seed box 3 and the working position of the seed box push-pull mechanism. Specifically, as shown in... Figure 17As shown, the elastic reset mechanism is two groups of V-shaped spring sheets 1031 placed horizontally, the lower end of each group is fixedly connected to the upper surface of the corresponding side of the clamping plate 103 through a bolt, and the upper end of the spring sheet 1031 abuts against the flange of the seed magazine 3 base 301 at the magazine port 206. Then, the spring sheet 1031 is checked by the elastic force, so that the seed magazine 3 can overcome the elastic force of the spring sheet 1031 under the gravity of the seed box 5 and the seed, and the rack 304 can contact the gear set, so as to continue to overcome the elastic force to the working position through transmission; when the seed magazine 3 becomes an empty magazine, the rack 304 is driven upward out of the meshing state by the reverse rotation of the motor. At this time, the weight of the empty magazine is not enough to overcome the elastic force, so that the empty magazine is pushed back to the upper edge of the continuous slide 203, and the reset is completed.

[0078] Optionally, in order to fully utilize the space, the last section of the continuous slide 203 is designed as a horizontal folded edge structure, such as a top view L-shaped structure. Further, the empty magazine recovery mechanism is also a linear motion mechanism, which is selected as the second linear motor 204 and is installed at the corner of the folded edge structure. The strategy of horizontal installation is adopted, so that the active end of the empty magazine recovery mechanism reciprocates along the folded edge direction, and the pushed empty magazine can be sent to the slide with a lateral folded edge for temporary storage. Further, a through hole 205 is processed at the end of the continuous slide 203, which is widened at the upper part, and the empty magazine temporarily stored in the recovery area can be taken out.

[0079] Optionally, due to the changeable situation in actual work and the human progress forgetting situation in the plan execution process, it is necessary to understand the current seed magazine planting situation in the working position, so that the general design is to print or paste labels in the visible position of the seed magazine 3. In order to facilitate use and reuse, electronic design is adopted in this embodiment, that is, an NFC label is installed on the side surface of the seed magazine 3, and relevant information is recorded; an NFC inductor is installed in the clamping plate 103, so as to read the information after the seed magazine falls, and feedback to the external screen.

[0080] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical solutions of the present application made by those skilled in the art do not deviate from the essence and scope of the technical solutions of the present application.
