Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting technology, in particular to a carrot harvesting and packing integrated machine. BACKGROUND

[0002] Carrot is a common crop, which has the effects of clearing heat and detoxifying, invigorating the spleen and stomach, reducing phlegm and relieving cough, and nourishing the liver and brightening the eyes. The lignin of carrot also has the functions of improving the body's anti-cancer immunity and indirectly eliminating cancer cells. With the rapid development of China's social economy and the continuous growth of population, more and more people pay attention to health, and the demand for carrots is also increasing.

[0003] The traditional picking method is manual picking, which is very laborious and inefficient. Although the existing carrot picking machine can efficiently pick carrots through chain pulling, it cannot adapt to different widths of the field ridge, and still needs human participation in the process of removing the picked carrots, packing, etc., which wastes human resources to some extent. The size of carrot tuber is different, and the ground exposure height difference is large, which leads to the problems of high power consumption, high loss and damage rate, poor environmental adaptability, easy congestion and entanglement of the existing carrot machine, and unstable field working performance. The planting area of carrot in China is widely distributed, and the climate, terrain, soil and other environments in different regions are significantly different, the sowing methods are diversified, and the planting density, row spacing, plant spacing, variety and ridge type are different. The existing carrot machine can only work on a fixed land, which is not compatible. How to solve the above technical problems is the direction of research for those skilled in the art. SUMMARY

[0004] The purpose of the present application is to provide a carrot harvesting and packing integrated machine to improve the harvesting efficiency of carrots.

[0005] In order to solve the above technical problems, the present application is realized by the following technical scheme:

[0006] A carrot harvesting and packing integrated machine, comprising an adjustable walking mechanism, a picking and conveying mechanism, a soil brushing and leaf removing mechanism and a packing mechanism installed on a rack,

[0007] The picking and conveying mechanism comprises a picking and conveying assembly, the picking and conveying assembly has two groups and is arranged in parallel along the left-right direction, each picking and conveying assembly comprises an installation plate, a plurality of synchronous pulleys and a double-sided conveyor belt, the installation plate is installed above the rack and inclined upward from front to back, a plurality of synchronous pulleys are arranged along the length direction of the installation plate, and the double-sided conveyor belt is tensioned on the synchronous pulleys;

[0008] The soil brushing and leaf removal mechanism includes a soil brushing mechanism and a leaf removal mechanism. There are two sets of soil brushing mechanisms, which are installed symmetrically on the underside of two mounting plates. Each set of soil brushing mechanisms includes a soil brush, a rotating disk, a pull rod, and a fixing rod. One end of the fixing rod is vertically installed at the bottom of the mounting plate. The pull rod is perpendicular to the fixing rod, and one end of the pull rod is rotatably connected to the other end of the fixing rod. The other end of the pull rod is equipped with the soil brush.

[0009] In one specific implementation, the pull rod has a slot extending along its length. A rotating disk is installed at the bottom of one of the synchronous pulleys and rotates synchronously with the pulley. The rotating disk has an eccentric hole. The soil brushing mechanism also includes a shaft that passes through the slot and is inserted into the eccentric hole. The shaft is movably arranged relative to the slot. When the rotating disk rotates with its corresponding synchronous pulley, the shaft slides in the slot, causing the soil brush to swing around the fixed rod with the pull rod, thus completing the soil brushing operation.

[0010] In one specific implementation, the soil brushes on the two mounting plates have a symmetrical arc-shaped structure, and the inner side of the soil brushes is provided with several protrusions, which are made of flexible material.

[0011] In one specific implementation, the leaf removal mechanism includes a cutter head mounted on the top of the mounting plate and located below the double-sided conveyor belt, with the surface of the cutter head being parallel to the surface of the mounting plate.

[0012] In one specific implementation, the adjustable walking mechanism consists of a wheel system, a slide, and a linkage mechanism.

[0013] The wheel system has two sets, which are arranged in parallel along the left and right direction. The two sets of wheel systems can be installed at the bottom of the frame, which can be close to or far from each other. Each set of wheel systems includes a bracket arranged in the front and back direction, a Max wheel mounted on the front side of the bracket, and a caster wheel mounted on the rear side of the bracket.

[0014] The slides are in two sets, which are installed parallel to each other in the front-back direction at the bottom of the frame. Each set of slides includes a flange seat installed on the left and right sides of the bottom of the frame, a smooth rod connected between the two flange seats, and a slider slidably sleeved on the smooth rod. The sliders in each set of slides correspond one-to-one with the wheel system in terms of quantity and position. The front and rear ends of the bracket in the wheel system are respectively fixed to the sliders in the two sets of slides corresponding to it.

[0015] The linkage mechanism is installed at the bottom of the frame and is used to drive the two sets of wheel trains to move closer or further apart. The linkage mechanism is installed between the two sets of wheel trains and includes a servo motor, a cloud plate, and connecting rods. The servo motor is installed at the bottom of the frame, the cloud plate is installed on the output end of the servo motor, and there are two connecting rods. One end of each connecting rod is hinged to the two ends of the cloud plate, and the other end is connected to the brackets in the wheel trains on both sides. The rotation of the cloud plate is controlled by the servo motor, so that the connecting rods drive the wheel trains on both sides to move closer or further apart.

[0016] In one specific implementation, the harvesting and conveying mechanism further includes a seeding assembly. The seeding assembly is installed on the frame and located below the harvesting and conveying mechanism. It includes an upper seeding box, a lower seeding box, a traction pipe, and a furrow opener arranged sequentially from top to bottom. The lower seeding box is equipped with a gear disk that can rotate around its own axis. The furrow opener communicates with the inner cavity of the traction pipe and has an open bottom. The rotation of the gear disk causes the seeds in the upper seeding box to fall into the lower seeding box, and then fall into the seeding trough sequentially through the traction pipe and the furrow opener.

[0017] In one specific embodiment, the packaging mechanism includes a bagging device, a strapping device, and a bottom conveying device, with the bottom conveying device located below the bagging device.

[0018] The bagging device includes a gripping assembly, a supporting rod, and a stop block. The gripping assembly consists of a lead screw, a lead screw slider, and a gripper. There are two lead screws, installed parallel to each other along the front and rear directions above the frame. Each lead screw has a slidably mounted lead screw slider. The gripper is connected to the lead screw sliders on the front and rear sides via a connecting plate, and slides synchronously with the lead screw sliders. The gripper includes an outer frame, a pushing block, a first spring, and gripping clamps. A slot is formed on one side of the outer frame. The gripping clamps consist of two symmetrical clamps, installed close to or far apart from each other on the bagging device. Inside the outer frame, the jaws on the outer end of the gripper extend out of the slot. One side of the push block is installed inside the outer frame via a first spring, and the other side of the push block abuts against the gripper. The stop block is installed on the side of the frame opposite to the jaws of the gripper. When the gripper slides with the screw slider until the jaws of the gripper abut against the stop block, the two grippers are forced to move away from each other under the action of the stop block. When the gripper moves away from the stop block with the screw slider, the two grippers move closer to each other. There are two bag support rods, one end of which is fixedly installed on the side of the frame away from the stop block, and the end closer to the stop block is a free end.

[0019] In one specific implementation, the strapping device includes a cable tie box. The upper surface of the cable tie box has a groove for accommodating cable ties. A push rod is installed on one side of the cable tie box. One end of the push rod is connected to a matching push plate that is locked in the groove for pushing the cable ties. A strapping assembly is provided at one end of the cable tie box along its length. The strapping assembly includes multiple arc-shaped grooves for accommodating the cable ties pushed by the push plate. The openings of the arc-shaped grooves face inward. The multiple arc-shaped grooves form a ring structure, and adjacent arc-shaped grooves are nested together. The arc-shaped grooves are connected by curved rods. The curved rods consist of two sets of curved rods that cross each other in a V-shape. Adjacent curved rods are hinged together.

[0020] In one specific implementation, the strapping device also includes a lever and a lever drive motor. The lever drive motor is mounted on the frame, and one end of the lever is connected to the output end of the lever drive motor, while the other end is connected to one of the curved rods.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1) This invention uses the cooperation of a rotating disk and a pull rod to convert the rotational power of the rotating disk into an oscillating force. One end of the pull rod is connected to the eccentric hole of the rotating disk, and the other end is connected to the soil brush, which enables the soil attached to the surface of the carrot to be removed effectively.

[0023] 2) The carrot harvesting and baling machine of the present invention has an adjustable walking mechanism with two sets of wheel systems, slides and linkages. The servo motor in the linkage controls the swing of the cloud plate, thereby driving the wheel system to slide on the smooth rod on the slide through the rod, so as to realize the mutual approach or distance of the two sets of wheel systems to meet the carrot harvesting needs of different row spacing, plant spacing, varieties and ridge types.

[0024] 3) The bagging device of the present invention can realize automatic bagging operation through the gripping assembly, the bag supporting rod and the stop block. Attached Figure Description

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] A carrot harvesting and baling integrated machine, see [link / reference] Figure 1 As shown, it includes an adjustable walking mechanism 1, a harvesting and conveying mechanism 2, a soil brushing and leaf removal mechanism 3, and a packaging mechanism 4, all mounted on a frame.

[0043] The extraction and conveying mechanism 2 includes an extraction and conveying component 201, see [link / details]. Figure 2 As shown, there are two sets of mining and pulling transmission components 201, which are arranged in parallel. Each set of mining and pulling transmission components 201 includes a mounting plate 20102, several synchronous pulleys 20101, and a double-sided conveyor belt 20103. The mounting plate 20102 is installed on the top of the frame at an upward inclination from front to back. The synchronous pulleys 20101 are mounted on the mounting plate 20102 and rotate around their own axis. The multiple synchronous pulleys 20101 are spaced apart along the length of the mounting plate 20102. The double-sided conveyor belt 20103 is tensioned on the wheel surface of the multiple synchronous pulleys 20101.

[0044] In this example, the soil brushing and leaf removal mechanism 3 includes a soil brushing mechanism 301 and a leaf removal mechanism 302. There are two sets of soil brushing mechanisms 301, which are respectively installed on two mounting plates 20102. (See [reference]). Figure 3 As shown, each set of soil brushing mechanisms 301 includes a soil brush 30105, a rotating disk 30101, a pull rod 30102, and a fixing rod 30103. One end of the fixing rod 30103 is fixedly mounted on the mounting plate 20102, and one end of the pull rod 30102 is rotatably mounted on the other end of the fixing rod 30103. The soil brush 30105 is mounted on the other end of the pull rod 30102. The pull rod 30102 has a slot extending along its own length. In this example, the rotating disk 30101 is mounted on the mounting plate 20102 from front to back. At the bottom of the two synchronous pulleys 20101, the rotating disk 30101 rotates synchronously with the corresponding synchronous pulley 20101. The rotating disk 30101 is provided with an eccentric hole. The soil brushing mechanism 301 also includes a shaft 30104 that passes through the slot and is inserted into the eccentric hole. The shaft 30104 is movably arranged relative to the slot. When the rotating disk 30101 rotates with its corresponding synchronous pulley 20101, the shaft 30104 slides in the slot, driving the soil brush 30105 to swing around the fixed rod 30103 with the pull rod 30102, thus completing the soil brushing operation.

[0045] Here, the soil brush 30105 on the two mounting plates 20102 has a symmetrical arc structure. The inner side of the soil brush 30105 is provided with several protrusions, which are made of flexible material. The protrusions are used to rub and brush the soil off the surface of the carrot.

[0046] See here. Figure 4 As shown, the leaf removal mechanism 302 includes a cutter head 30201 mounted on the top of the mounting plate 20102 and located below the double-sided conveyor belt 20103. The surface of the cutter head 30201 is parallel to the surface of the mounting plate 20102. A gear set is provided between a synchronous pulley 20101 at the top of the mounting plate 20102 and the cutter head 30201, so that the cutter head 30201 can rotate with the synchronous pulley 20101 to complete the leaf removal operation. Specifically, a first pinion 30202 is provided at the bottom of a synchronous pulley 20101 at the top of the mounting plate 20102, and a second pinion 30203 is provided at the top of the cutter head 30201. A transmission gear 30204 is provided between the first pinion 30202 and the second pinion 30203, and meshes with both of them. Through the mutual cooperation of the first pinion 30202, the second pinion 30203 and the transmission gear 30204, the cutter head 30201 can rotate with the synchronous pulley 20101.

[0047] Furthermore, in this example, a support 20106 is also installed on the front end of each mounting plate 20102 in the sampling and transfer assembly 201. For example... Figure 2 As shown, the supports 20106 on the two mounting plates 20102 cooperate with each other to limit the carrots to be harvested. The double-sided conveyor belts 20103 on the two mounting plates 20102 rotate inward. Through the rotation of the synchronous pulley 20101, the carrots are pulled out of the soil by the friction and traction of the double-sided conveyor belts 20103.

[0048] Here, each set of harvesting and conveying components 201 also includes a first reducer 20105 and a bevel gear set 20104. The first reducer 20105 is mounted on the frame, and the bevel gear set 20104 includes two bevel gears. One bevel gear is mounted on the output end of the first reducer 20105, and the other bevel gear is mounted on the lower end of the rotating shaft of a synchronous pulley 20101 located at the foremost end of the mounting plate 20102. That is, the synchronous pulley 20101 located at the foremost end is the driving pulley. The two bevel gears mesh with each other, and their axes are perpendicular to each other. The first reducer 20105 drives the bevel gear on its output end to rotate, which in turn causes the driving pulley to rotate through the rotation of the other bevel gear meshing with it, thereby driving the double-sided conveyor belt 20103 to rotate.

[0049] In this example, the harvesting and conveying mechanism 2 also includes a seeding component 202, see [link / reference]. Figure 5 , 6 As shown, the sowing assembly 202 is mounted on the frame and located below the harvesting and conveying mechanism 2. It includes, from top to bottom, an upper sowing box 20201, a lower sowing box 20202, a traction pipe 20204, and a furrow opener 20205. The lower sowing box 20202 contains a gear disk 20203 that can rotate around its own axis. The furrow opener 20205 communicates with the inner cavity of the traction pipe 20204, and its bottom is open. The rotation of the gear disk 20203 causes the seeds in the upper sowing box 20201 to fall sequentially into the lower sowing box 20202, and then sequentially through the traction pipe 20204 and the furrow opener 20205 into the sowing trough, thus achieving sowing. Here, the front end of the furrow opener 20205 is an acute-angled triangular structure formed by two plates joined together, which reduces resistance during furrowing. Here, the power for the seeding assembly 202 comes from the DC geared motor 20206, and the gear disk 20203 is installed on the output end of the DC geared motor 20206.

[0050] For details, see Figure 7As shown, the adjustable walking mechanism 1 consists of a wheel train 101, a slide 102, and a linkage mechanism 103. The wheel train 101 has two sets, arranged parallel to each other in the left-right direction. The two sets of wheel trains 101 are mounted at the bottom of the frame, allowing them to move closer or further apart. Each set of wheel trains 101 includes a bracket 10101 arranged in the front-rear direction, a Max wheel 10102 mounted on the front side of the bracket 10101, and a caster wheel 10103 mounted on the rear side of the bracket 10101. The slide 102 has two sets, installed parallel to each other in the front-rear direction at the bottom of the frame. Each set of slides 102 includes flange seats 1020 mounted on the left and right sides of the bottom of the frame. 2. A smooth rod 10203 connected between two flange seats 10202, and a slider 10201 slidably sleeved on the smooth rod 10203. The sliders 10201 in each set of slides 102 correspond one-to-one with the wheel train 101 in terms of both number and position. The front and rear ends of the bracket 10101 in the wheel train 101 are respectively fixed to the sliders 10201 in the two sets of slides 102. A linkage mechanism 103 is installed at the bottom of the frame and is used to drive the two sets of wheel trains 101 to move closer or further apart. The linkage mechanism 103 is installed between the two sets of wheel trains 101 and includes a servo motor 10303, a cloud-shaped plate 10302, and a linkage 10301. (See [reference]). Figure 8 As shown, the servo motor 10303 is installed at the bottom of the frame, the cloud plate 10302 is installed on the output end of the servo motor 10303, and there are two connecting rods 10301. One end of the two connecting rods 10301 is hinged to the two ends of the cloud plate 10302, and the other end is connected to the brackets 10101 in the wheel system 101 on both sides. By controlling the rotation of the cloud plate 10302 through the servo motor 10303, the connecting rods 10301 drive the brackets 10101 on both sides to slide on the smooth rod 10203 with the slider 10201, thereby realizing the wheel system 101 moving closer or further apart.

[0051] The adjustable walking mechanism 1 described above uses a servo motor 10303 to control the rotation of the cloud plate 10302, causing the connecting rod 10301 to pull the bracket 10101 in the two sets of wheel systems 101. The distance between the two sets of wheel systems 101 is adjusted by the sliding of the sliders 10201 at both ends of the bracket 10101 on the smooth rod 10203, so as to meet the row spacing or plant spacing requirements during actual carrot harvesting. The use of the Max mother wheel 10102 and the universal wheels 10103 enables four-way movement, meeting the left and right movement requirements of the adjustable walking mechanism 1.

[0052] Furthermore, the packaging mechanism 4 includes a bagging device 401, a strapping device 402, and a bottom conveying device 403, see [link to documentation]. Figure 9 As shown. The bottom conveying device 403 is installed below the bagging device 401.

[0053] See Figure 10As shown, the bagging device 401 includes a gripping assembly, a bag-supporting rod 40107, and a stop block 40108. The gripping assembly consists of a lead screw 40101, a lead screw slider 40102, and a gripper. There are two lead screws 40101, which are installed parallel to each other in the front and rear directions on the top of the frame. A lead screw slider 40102 is slidably mounted on each lead screw 40101. One of the lead screw sliders 40102 is equipped with a sliding motor for driving the lead screw slider 40102 to slide on the lead screw 40101. The gripper is connected to the lead screw sliders 40102 on the front and rear sides through a connecting plate. The gripper slides synchronously with the lead screw sliders 40102. The gripper includes an outer frame 40104, a push block 40105, a first spring 40103, and a gripper clamp 40106. A slot is opened on one side of the outer frame 40104. The gripper clamp 40106 consists of two symmetrical clamps. The grippers 40106 are mounted close to or far apart within the outer frame 40104. The jaws on the outer end of the gripper 40106 extend beyond the slot. One side of the push block 40105 is mounted within the outer frame 40104 via a first spring 40103, and the other side of the push block 40105 abuts against the gripper 40106. A stop block 40108 is mounted on the side of the frame opposite the jaws of the gripper 40106. The gripper slides with the lead screw slider 40102. When the jaws of the gripper 40106 abut against the stop block 40108, the two grippers 40106 are forced to move away from each other under the action of the stop block 40108. When the gripper moves away from the stop block 40108 along with the lead screw slider 40102, the two grippers 40106 move closer to each other. There are two bag support rods 40107. One end is fixedly installed on the side of the frame away from the stop block 40108, and the end closer to the stop block 40108 is the free end.

[0054] Specifically, the packaging bags are usually made of burlap sacks. An area for placing burlap sacks is set on the side of the frame where the stop block 40108 is installed. A baffle 40109 is set on the frame to prevent the burlap sacks from falling. The burlap sacks are manually hooked onto the stop block 40108 with the side facing the gripper. There are two holes on the side of the burlap sack facing the gripper that cooperate with the bag support rod 40107. When the carrots are being packaged, the sliding motor drives the lead screw slider 40102 to move the gripper closer to the stop block 40108 until it abuts against the stop block 40108. This causes the two clamps to move away from each other and open the jaws to contact the burlap sack. Then, the sliding motor drives the lead screw slider 40102 to move away from the stop block 40108, and the jaws clamp the burlap sack. At the same time, the two holes on the burlap sack pass through the bag support rod 40107, so that the burlap sack opens to receive carrots falling from the top of the mounting plate 20102.

[0055] Once the bag is full of carrots, the sliding motor drives the lead screw slider 40102 to move the gripper closer to the stop block 40108 until the jaws open, detaching the sack from the support rod 40107. Then, the binding device 402 is activated to bind the sack. (See here for more details.) Figure 11 As shown, the strapping device 402 includes a cable tie box 40201. The upper surface of the cable tie box 40201 has a channel for accommodating cable ties. A push rod 40202 is installed on one side of the cable tie box 40201. One end of the push rod 40202 is connected to a matching push plate 40203, which is engaged in the channel and used to push the cable ties. A strapping assembly is provided at one end of the cable tie box 40201 along its length. The strapping assembly includes multiple arc-shaped grooves 40205 and a... The cable tie pushed by the receiving push plate 40203 has an inwardly facing arc-shaped groove 40205. Multiple arc-shaped grooves 40205 form a ring structure, and adjacent arc-shaped grooves 40205 are nested together. The arc-shaped grooves 40205 are connected by curved rods 40204. The curved rods 40204 are composed of two sets of curved rods 40204 that cross each other in a V shape. Adjacent curved rods 40204 are hinged together.

[0056] The cable tie box 40201 has a channel that can only hold one cable tie. The cable tie box 40201 consists of a spring and a partition, with the partition serving as the bottom plate of the channel. The cable tie is ejected by pressing the partition with a push plate 40203 on the push rod 40202. In this example, the push rod 40202 is composed of multiple sequentially hinged rods. A drive motor on the frame drives the push rod 40202 to move the push plate 40203 along the channel of the cable tie box 40201. The cable tie in the channel extends into the opening of the adjacent arc-shaped groove 40205 as the push plate 40203 pushes it, forming a ring along the direction of the arc-shaped groove 40205. Then, the curved rod 40204 on the arc-shaped groove 40205 tightens, simultaneously tightening the arc-shaped groove 40205 to secure the opening of the sack.

[0057] See here. Figure 11 As shown, the strapping device 402 also includes a lever 40206 and a lever drive motor 40207. The lever drive motor 40207 is mounted on the frame. One end of the lever 40206 is connected to the output end of the lever drive motor 40207, and the other end is connected to one of the curved rods 40204. The lever 40206 is driven by the lever drive motor 40207 to swing, causing the curved rods 40204 to move closer or further apart to achieve the bag-tying operation.

[0058] After the bags are tied, they are conveyed out of the device via the bottom conveyor 403. (See also...) Figure 11As shown, the bottom-side transmission device includes multiple sets of rollers 40302 mounted on the frame. Each set of rollers 40302 is spaced apart along the left and right direction of the frame. There are multiple rollers 40302 in each set, and the multiple rollers 40302 are connected by a bearing. Corresponding rollers 40302 in the multiple sets of rollers 40302 are connected by a track 40301 for transmission.
