Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to an all-in-one carrot harvesting and packaging machine. Background Art

[0002] Carrot is a common crop, which has the effects of clearing away heat and detoxifying, strengthening the spleen and stomach, resolving phlegm and relieving cough, nourishing the liver and improving eyesight. The lignin in carrots also has the function of improving the body's anti-cancer immunity and indirectly destroying cancer cells. With the rapid development of my country'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 way of picking is manual picking, which is not only very laborious but also inefficient. The existing carrot picking machine, although it can efficiently pick carrots by chain extraction, cannot adapt to ridges of different widths, and it is also necessary to remove dust and soil from the picked carrots, and pack them, which still requires human participation, wasting human resources to a certain extent. The carrot tubers are of different sizes and the height of the exposed ground varies greatly, resulting in the existing carrot machines having high power consumption, high loss and damage rate, poor environmental adaptability, easy congestion and entanglement, and unstable field performance. However, the carrot planting areas in my country are widely distributed, and the climate, topography, soil and other environmental differences in various regions are significant. The sowing methods are diversified, and there are differences in planting density, row spacing, plant spacing, variety and ridge type. The existing carrot machines can only operate on a fixed land and are incompatible.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention: A carrot harvesting and packaging machine, see Figure 1 As shown, it includes an adjustable walking mechanism 1 installed on a frame, a picking and conveying mechanism 2, a soil brushing and leaf removing mechanism 3 and a packaging mechanism 4.

[0017] The picking and conveying mechanism 2 includes a picking and conveying assembly 201, see Figure 2 As shown, there are two groups of picking and pulling transmission components 201, which are arranged in parallel. Each group of picking and pulling transmission components 201 includes a mounting plate 20102, a plurality of synchronous pulleys 20101, and a double-sided conveyor belt 20103. The mounting plate 20102 is installed on the top of the frame and tilted upward from front to back. The synchronous pulleys 20101 are installed on the mounting plate 20102 to rotate around their own axial direction, and the plurality of synchronous pulleys 20101 are arranged at intervals along the length direction of the mounting plate 20102. The double-sided conveyor belt 20103 is tensioned on the wheel surfaces of the plurality of synchronous pulleys 20101.

[0018] In this example, the soil brushing and leaf removing mechanism 3 includes a soil brushing mechanism 301 and a leaf removing mechanism 302. The soil brushing mechanism 301 has two groups, which are respectively installed on two mounting plates 20102. Figure 3 As shown, each set of soil brushing mechanism 301 includes a soil brush 30105, a rotating disk 30101, a pull rod 30102 and a fixed rod 30103. One end of the fixed 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 fixed rod 30103. The soil brush 30105 is mounted on the other end of the pull rod 30102. A slot extending along the length direction of the pull rod 30102 is provided. 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 pulleys 20101. An eccentric hole is provided on the rotating disk 30101. The soil brushing mechanism 301 also includes a shaft rod 30104 passing through the slot and inserted in the eccentric hole. The shaft rod 30104 is movably arranged relative to the slot. When the rotating disk 30101 rotates with the corresponding synchronous pulley 20101, the shaft rod 30104 slides in the slot, driving the soil brush 30105 to swing around the fixed rod 30103 with the pull rod 30102 to complete the soil brushing operation.

[0019] Here, the soil brush 30105 on the two mounting plates 20102 is in a symmetrical arc-shaped structure, and a plurality of protrusions are arranged on the inner side of the soil brush 30105. The protrusions are made of a flexible material, and the soil is brushed off by rubbing the surface of the carrot.

[0020] Here, see Figure 4As shown, the leaf removal mechanism 302 includes a knife disc 30201 installed on the top of the mounting plate 20102 and located below the double-sided conveyor belt 20103, and the surface where the knife disc 30201 is located is arranged parallel to the surface where the mounting plate 20102 is located. A gear set is arranged between a synchronous pulley 20101 on the top of the mounting plate 20102 and the cutter disc 30201 so that the cutter disc 30201 can rotate along with the rotation of the synchronous pulley 20101 to complete the leaf removal operation. Specifically, a first pinion 30202 is arranged at the bottom of a synchronous pulley 20101 on the top of the mounting plate 20102, a second pinion 30203 is arranged on the upper part of the cutter disc 30201, and a transmission gear 30204 meshing with the first pinion 30202 and the second pinion 30203 is arranged between the first pinion 30202 and the second pinion 30203. Through the mutual cooperation of the first pinion 30202, the second pinion 30203 and the transmission gear 30204, the cutter disc 30201 can rotate along with the rotation of the synchronous pulley 20101.

[0021] In addition, in this example, a support 20106 is also installed on the front end of each mounting plate 20102 in the harvesting and transmission assembly 201. Figure 2 As shown, the supporters 20106 on the two mounting plates 20102 cooperate with each other to limit the position of the carrots to be harvested, and 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 under the action of the friction and traction of the double-sided conveyor belts 20103.

[0022] Here, each group of the picking and transmission assembly 201 also includes a first reducer 20105 and a bevel gear set 20104. The first reducer 20105 is installed on the frame. The bevel gear set 20104 includes two bevel gears, one of which is installed on the output end of the first reducer 20105, and the other is installed on the lower end of the rotating shaft of a synchronous pulley 20101 located at the front end of the mounting plate 20102, that is, the synchronous pulley 20101 located at the front end is the driving wheel, and the two bevel gears are meshed and the axis lines of the two bevel gears are arranged perpendicularly. The bevel gear on the output end of the first reducer 20105 is driven to rotate, and then the driving wheel is rotated by the rotation of the other bevel gear meshed with it, thereby driving the double-sided conveyor belt 20103 to rotate.

[0023] In this example, the picking and conveying mechanism 2 also includes a sowing component 202, see Figure 5 , 6As shown, the sowing assembly 202 is installed on the frame and is located below the picking and conveying mechanism 2, including an upper sowing box 20201, a lower sowing box 20202, a traction tube 20204 and a furrow opener 20205 arranged in sequence from top to bottom, a gear plate 20203 capable of rotating around its own axis is installed in the lower sowing box 20202, the furrow opener 20205 is connected to the inner cavity of the traction tube 20204, and the bottom of the furrow opener 20205 is open, and the seeds in the upper sowing box 20201 fall into the lower sowing box 20202 in sequence through the rotation of the gear plate 20203, and fall into the sowing groove in sequence through the traction tube 20204 and the furrow opener 20205, thereby achieving sowing. Here, the front end of the furrow opener 20205 is an acute triangle structure composed of two plates spliced ​​together, and the resistance encountered by the structure during the furrowing process is small. Here, the power of the sowing component 202 comes from the DC reduction motor 20206, and the gear plate 20203 is installed on the output end of the DC reduction motor 20206.

[0024] For details, see Figure 7 As shown, the adjustable walking mechanism 1 is composed of a wheel train 101, a slide 102 and a connecting rod mechanism 103. The wheel train 101 has two groups, which are arranged in parallel along the left and right directions. The two groups of wheel trains 101 can be installed at the bottom of the frame close to or away from each other. Each group of wheel trains 101 includes a bracket 10101 arranged in the front-to-back direction, a Max mother wheel 10102 installed on the front side of the bracket 10101, and a universal wheel 10103 installed on the rear side of the bracket 10101; there are two groups of slides 102, which are installed in parallel along the front-to-back direction at the bottom of the frame, and each group of slides 102 includes flange seats 1020 installed on the left and right sides of the bottom of the frame. 2. A polished rod 10203 connected between two flange seats 10202, a slider 10201 slidably sleeved on the polished rod 10203, the sliders 10201 in each set of slides 102 correspond to the gear train 101 in number and position, and the front and rear ends of the bracket 10101 in the gear train 101 are respectively fixed to the sliders 10201 in the two corresponding sets of slides 102; the connecting rod mechanism 103 is installed at the bottom of the frame and is used to drive the two sets of gear trains 101 to move closer to or away from each other. The connecting rod mechanism 103 is installed between the two sets of gear trains 101, including a steering gear 10303, a cloud piece 10302 and a connecting rod 10301, see Figure 8 As shown, the servo 10303 is installed at the bottom of the frame, the cloud piece 10302 is installed on the output end of the servo 10303, and there are two connecting rods 10301. One end of the two connecting rods 10301 is hinged to the two end portions of the cloud piece 10302 respectively, and the other end is connected to the brackets 10101 in the gear trains 101 on both sides. The rotation of the cloud piece 10302 is controlled by the servo 10303, so that the connecting rod 10301 drives the brackets 10101 on both sides to slide on the light rod 10203 with the slider 10201, thereby realizing the mutual approach or distance of the gear trains 101.

[0025] By using the above-mentioned adjustable traveling mechanism 1, the cloud sheet 10302 is controlled to rotate by the steering gear 10303, so that the connecting rod 10301 pulls the bracket 10101 in the two sets of gear trains 101, and the sliders 10201 at both ends of the bracket 10101 slide on the bare rod 10203 to adjust the spacing between the two sets of gear trains 101 to meet the actual row spacing or plant spacing requirements during carrot harvesting. The Max mother wheel 10102 and the universal wheel 10103 can achieve four-way movement to meet the requirements of the adjustable traveling mechanism 1 to move left and right.

[0026] Furthermore, the packaging mechanism 4 includes a bagging device 401, a strapping device 402 and a bottom transmission device 403, see Fig. 9 The bottom transmission device 403 is installed below the bagging device 401.

[0027] See also Fig.10 As shown, the bagging device 401 includes a gripping clamp assembly, a bag supporting rod 40107 and a stopper 40108. The gripping clamp assembly consists of a screw rod 40101, a screw rod slider 40102 and a gripping clamp. There are two screw rods 40101, which are installed on the upper part of the frame in parallel along the front and rear directions. A screw rod slider 40102 is slidably installed on each screw rod 40101. A sliding motor for driving the screw rod slider 40102 to slide on the screw rod 40101 is installed on one of the screw rod sliders 40102. The gripping clamp is connected to the screw rod sliders 40102 on the front and rear sides through a connecting plate. The gripping clamp slides synchronously with the screw rod slider 40102. The gripping clamp includes an outer frame 40104, a pushing block 40105, a first spring 40103 and a gripping clamp 40106. A slot is opened on one side surface of the outer frame 40104. The gripping clamp 40106 consists of two symmetrical clamps. The two clamps are symmetrical. The two clamps 40106 are installed in the outer frame 40104 close to or far from each other, the jaws on the outer end of the grab clamp 40106 extend out of the slot, one side of the push block 40105 is installed in the outer frame 40104 through the first spring 40103, the other side of the push block 40105 abuts against the grab clamp 40106, and the stopper 40108 is installed on the side of the frame opposite to the jaws of the grab clamp 40106. When the grab clamp slides with the screw slider 40102 When the jaws of the grabbing clamp 40106 abut against the block 40108, the two grabbing clamps 40106 are forced to move away from each other under the action of the block 40108, and when the grabbing clamp follower slider 40102 moves away from the block 40108, the two grabbing clamps 40106 move closer to each other; there are two bag-supporting rods 40107, one end of which is fixedly installed on the side frame away from the block 40108, and the end close to the block 40108 is a free end.

[0028] Specifically, the packaging bags are usually packaged in sacks, and an area for placing the sacks is provided on the frame, on the side where the block 40108 is installed, and a baffle 40109 is provided on the frame to prevent the sacks from falling. The side of the sack facing the gripping clamp is manually hooked on the block 40108, and the side of the sack facing the gripping clamp is provided with two holes that cooperate with the bag-supporting rod 40107. When packing carrots, the gripping clamp is driven to approach the position of the block 40108 until it abuts against the block 40108 by the sliding motor driving the lead screw slider 40102, so that the two clamps move away from each other and the jaws open, and the jaws contact the sack, and then the sliding motor is driven to drive the lead screw slider 40102 to move away from the block 40108, and the jaws clamp the sack. At the same time, the two holes on the sack pass through the bag-supporting rod 40107, so that the sack opens to receive the carrots dropped from the top of the mounting plate 20102.

[0029] After the carrots in the packaging bag are fully collected, the sliding motor drives the screw slider 40102 to drive the gripper to move closer to the block 40108 again until the jaws open, and the sack is separated from the bag support rod 40107, and then the strapping device 402 is started to strap. Fig.11 As shown, the strapping device 402 includes a strapping box 40201, the upper surface of which is provided with a groove for accommodating the strapping, a push rod 40202 is installed on one side of the strapping box 40201, one end of the push rod 40202 is connected with a push plate 40203 which is arranged in the groove and is used to push the strapping, and a strapping assembly is provided at one end of the strapping box 40201 in the length direction, and the strapping assembly includes a multi-section arc groove 40205, a In order to accommodate the cable tie pushed by the push plate 40203, the notch of the arc groove 40205 is set inward, and the multiple arc grooves 40205 form an annular structure, and the two adjacent arc grooves 40205 are mutually socketed, and the arc grooves 40205 are connected by a curved rod 40204. The curved rod 40204 is composed of two groups of curved rods 40204 that cross each other in a V shape at the upper and lower ends, and the two adjacent curved rods 40204 are hingedly set.

[0030] The slot of the cable tie box 40201 can only accommodate one cable tie. The cable tie box 40201 is composed of a spring and a partition. The partition is the bottom plate of the slot. The push plate 40203 on the push rod 40202 presses the partition to pop out the cable tie. In this example, the push rod 40202 is composed of a plurality of rods hinged in sequence.
