[0029] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0030] like Figure 1 and Figure 2 The double-cart sowing and sorting machine shown mainly comprises a scanning and feeding assembly 1, a lifting assembly 2, a lateral sorting module 3 and two groups of material receiving assemblies 4 and other structures that cooperate with each other.

[0031] The scanning and feeding assembly 1 includes a first supporting frame 11 , a first circulating feeding belt set 12 , a scanning mechanism 13 and other structures.

[0032] There are multiple groups of first circulating conveyor belt groups 12 (in the present embodiment, there are two groups of first circulating conveyor belt groups 12, so that two materials can be placed for processing), which are rotatably mounted on the first supporting frame 11 and arranged side by side; the scanning mechanism 13 is mounted above the first supporting frame 11, and is used to scan the material (usually the material is manually aligned with the scanning mechanism 13, and after the material is scanned, the material is manually placed on the first circulating conveyor belt group 12 to move downstream). The first circulating conveyor belt group 12 can be rotatable in an existing conventional manner, such as installing at least two rotating rollers on the first supporting frame 11 (usually the rotating rollers are installed on the first supporting frame 11 by bearings), installing the first circulating conveyor belt group 12 on these rotating rollers, and connecting one rotating roller to the motor through a belt, so that when the motor is working, the belt can be used to drive the rotating roller to work, thereby driving the circulating rotation of the first circulating conveyor belt group 12; it can also be that two electric rollers (one active electric roller and one driven electric roller) are installed on the first supporting frame 11, and the first circulating conveyor belt group 12 is installed on the two electric rollers, so that the two electric rollers are used to drive the circulating rotation of the first circulating conveyor belt group 12.

[0033] In this embodiment, the scanning mechanism 13 includes a display screen installed above the first circulating feed belt group 12 (located on the side wall of the lifting component 2), a keyboard tray installed on the side wall of the lifting component 2 and arranged horizontally (the keyboard tray is slightly lower than the display screen), a horizontal hanger installed on the lifting component 2 (the horizontal hanger is located below the keyboard tray), a scanning bracket installed on the horizontal hanger and adjustable in angle (the angle can be adjusted in a conventional manner, such as opening a long slot on the scanning bracket, and manually adjusting the angle by using the tightness of the installation of fasteners such as bolts), an industrial computer connected to the display screen, and a barcode scanner installed on the scanning bracket and connected to the industrial computer, the barcode scanner is used to identify conventional identification codes such as QR codes and transmit corresponding information to the industrial computer, so that it can be displayed on the display screen. In actual use, each material receiving unit 43 of the material receiving component 4 can be numbered, and this information can be input into the industrial computer and each material receiving unit 43 can be set to receive different materials. In this way, after the barcode scanner recognizes the QR code, the industrial computer can calculate which material receiving unit 43 receives the material, and thus transport the material to the corresponding material receiving unit 43 through the cooperation of the lifting component 2 and the horizontal sorting module 3.

[0034] The lifting assembly 2 includes a first supporting vertical frame body 21 disposed adjacent to the first supporting frame body 11, a lifting mechanism 22 mounted on the first supporting vertical frame body 21, and a plurality of second circulating conveyor belt groups 23 mounted on the lifting mechanism 22 and corresponding one-to-one with the first circulating conveyor belt group 12. In the present embodiment, there are two groups of the first circulating conveyor belt group 12 and the second circulating conveyor belt group 23 (the structure of the second circulating conveyor belt group 23 is substantially the same as that of the first circulating conveyor belt group 12, except that the second circulating conveyor belt group 23 also has a corresponding limit baffle mounted on the supporting frame body, which can prevent the carried material from falling when the second circulating conveyor belt group 23 is lifted up and down).

[0035] The lifting mechanism 22 includes a first mounting seat 221 mounted on the first supporting vertical frame body 21, a first pulley 222 mounted in the first mounting seat 221, a first roller 227 mounted on the first supporting vertical frame body 21 and arranged opposite to the first pulley 222 (another pulley or similar structure is arranged on the first roller 227), a first transmission belt 223 sleeved on the first roller 227 and the first pulley 222, a first adapter block 224 connected to the first transmission belt 223, a second track groove 226 mounted on the inner side of the first supporting vertical frame body 21 and arranged vertically, and a bracket 225 connected to the first adapter block 224 and slidably mounted on the second track groove 226, and the second circulating conveyor belt group 23 is installed on the bracket 225. The lifting mechanism 22 can transport materials to the horizontal sorting components 32 at different levels. In this embodiment, the bracket 225 includes a first mounting frame 2251 connected to the first adapter block 224, a plurality of first rollers 2252 rotatably mounted on the first mounting frame 2251 and matched with the second track groove 226, at least one second roller 2253 rotatably mounted on the first mounting frame 2251 for abutting against the inner wall of the second track groove 226, and a support plate 2254 mounted on the first mounting frame 2251 and connected to the second circulating conveyor belt group 23, so that the second circulating conveyor belt group 23 can be smoothly lifted and lowered, that is, the lifting and lowering stability of the second circulating conveyor belt group 23 can be improved. The lifting mechanism 22 is divided into two groups, which are connected to the second circulating conveyor belt group 23 in a one-to-one correspondence; the two lifting mechanisms 22 work synchronously, thereby driving the two second circulating conveyor belt groups 23 to be lifted and lowered synchronously.

[0036] The transverse sorting module 3 includes a support frame 31 arranged on one side of the first support vertical frame 21 and a plurality of transverse sorting components 32 installed on the support frame 31 and spaced apart from each other in the upper and lower directions; the plurality of second circulating conveyor belt groups 23 cooperate with any one of the transverse sorting components 32 under the drive of the lifting mechanism 22, thereby transferring the materials on the second circulating conveyor belt groups 23 to the corresponding transverse sorting components 32.

[0037] Specifically, each group of transverse sorting components 32 includes a matching transverse track mechanism 321, a sorting mechanism 322 and a driving mechanism 323.

[0038] The transverse track mechanism includes a transverse support frame and a first track groove 3211 installed on the inner side of the transverse support frame; for example, the transverse support frame may include two first long profiles that are parallel to each other and spaced apart and two first short profiles connected between the two first long profiles, and the two first short profiles are also parallel to each other and spaced apart, so that the first long profiles and the first short profiles form a frame structure. The first track groove 3211 is installed on the inner side of the first long profile. In addition, limit seats are also installed at both ends of the inner side of the first track groove 3211 to prevent the sorting mechanism 322 from colliding with the transverse track mechanism 321.

[0039] The sorting mechanism 322 is composed of multiple groups, which are connected in pairs. The specific number can be reasonably selected according to the actual application scenario. In this embodiment, the sorting mechanism 322 is composed of two groups, which are connected together and move synchronously. In this way, multiple materials can be put in at one time, which greatly reduces the waiting time for each component to reset after putting in materials one by one, and effectively improves the working efficiency of the double-car seeding and sorting machine. Each group of sorting mechanisms 322 includes a walking unit movably mounted on the first track groove 3211 and a sorting unit mounted on the walking unit for transporting materials in a direction perpendicular to the first track groove 3211. Specifically, the walking unit includes a support body 3221 disposed inside the first track groove 3211, a plurality of walking rollers 3222 rotatably mounted on both sides of the support body 3221 and matched with the first track groove 3211, a plurality of limiting rollers 3223 rotatably mounted on both sides of the support body 3221 for abutting against the inner wall of the first track groove 3211 of the track groove (at this time, the axis of the limiting roller 3223 is perpendicular to the axis of the walking roller 3222; that is, the axis of the walking roller 3222 is horizontally arranged and the axis of the limiting roller 3223 is vertically arranged), and a second adapter block 3224 mounted on the support body 3221. In this embodiment, the support body 3221 includes a supporting folding plate disposed inside the first track groove 3211 and a reinforcing plate connected between the two supporting folding plates, and the second adapter block 3224 is fixed on the reinforcing plate. The sorting unit includes two first support plates 3225 installed on the walking unit and perpendicular to the first track groove 3211 (that is, the two first support plates 3225 are parallel and spaced apart, they are installed on the supporting folding plates and are usually located on both side surfaces of the supporting folding plates), first electric rollers 3226 installed at both ends of the two first support plates 3225 (one first electric roller 3226 is an active roller and the other is a driven roller), and a circulating conveyor belt 3227 installed on the first electric rollers 3226, so that the circulating conveyor belt 3227 can be driven to rotate by the operation of the electric rollers 3226 to transport the materials thereon in a direction perpendicular to the first track groove 3211.

[0040] Combined with the previous description, the working principle of the horizontal sorting module 3 is that the sorting unit cooperates with the second circulating conveyor belt group 23 to receive the material transported by the second circulating conveyor belt group 23, and moves along the horizontal track mechanism 321 driven by the driving mechanism 323; when reaching the designated position, the sorting unit works to make the circulating conveyor belt 3227 rotate and transport the material thereon to the corresponding material receiving unit 43.

[0041] The driving mechanism is mounted on the transverse support frame and connected to the walking unit, and is used to drive the walking unit to move on the first track groove 3211. Specifically, the driving mechanism includes a fixed seat 3231 (two) mounted on the inner side of the first short profile, a second pulley 3232 rotatably mounted on the fixed seat 3231, a belt 3233 mounted on the second pulley 3232, and a motor 3234 connected to any second pulley 3232 for driving the rotation thereof, and the motor 3234 can be mounted on the fixed seat 3231 or on the transverse support frame; in addition, the second adapter block 3224 is also connected to the belt 3233, that is, the second adapter block 3224 is also mounted on the belt 3233 and moves synchronously with the belt 3233. In this way, when the motor 3234 is working, it can drive the belt 3233 to move, and then drive the two groups of sorting units to move synchronously, so that two materials can be transported at a time, which greatly improves the sorting efficiency (mainly greatly reducing the waiting time for each component to reset after the materials are put in one by one). In this embodiment, the sorting unit further includes second support plates 3228 mounted one-to-one on the first support plates 3225 and covers 3229 mounted on the two second support plates 3228 to prevent the materials from being disturbed by external factors.

[0042] There are two groups of material receiving components 4, which are arranged on both sides of the horizontal sorting module 3. Since the sorting mechanism 322 can transport materials in both directions, by setting up two groups of material receiving components 4, the sorting capacity is doubled while only increasing a small amount of space. Specifically, each group of material receiving components 4 includes a material receiving frame 41, multiple groups of inclined material frames 42 installed on the material receiving frame 41 and arranged at intervals up and down, and material receiving containers 43 arranged in sequence on each group of inclined material frames 42 and matched with the sorting unit, and the multiple groups of inclined material frames 42 correspond one to one with the multiple groups of horizontal sorting components 32.

[0043] In general, by cooperating with the scanning and feeding component 2, the lifting component 3, the horizontal sorting module 4 and the material receiving component 5, the scanned and identified materials can be quickly and accurately introduced into the set material receiving container; and the sorting mechanisms are connected in pairs and can move synchronously, so that multiple materials can be put in at one time, which greatly reduces the waiting time for each component to reset after putting in the materials one by one; the working efficiency of the entire double-car seeding and sorting machine is greatly improved, and the material processing efficiency reaches ≥1500 pieces / h.

[0044] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
