Description

Technical Field

[0001] The invention relates to the technical field of radish harvesting equipment, in particular to an all-in-one carrot harvesting and tassel removal machine. Background Art

[0002] In current research, there are two basic approaches to integrated carrot harvesters. One involves using a topping device to break up the top stems and leaves, then directly picking up the carrots with a digging shovel to complete the harvest. The other involves using a dual conveyor belt to clamp the carrots, plucking them, and then cutting the tops.

[0003] The first model, with its wide harvesting units and wide spacing between harvesting units, is only suitable for large-scale, orderly carrot cultivation on plains. It cannot meet the diverse and complex agronomic requirements of my country's regions. Furthermore, the high cost of introduction and low return on investment make it difficult to promote among a large number of farmers.

[0004] The second type of machine is compact and has better adaptability, but the machine has certain requirements on the properties of the soil, and it is easy for the machine to be inaccurate, resulting in missed clamping, which reduces the clamping efficiency and makes it impossible to clamp out the soil.

[0005] In addition, some areas still use crude carrot-turning mechanisms, typically attached to the back of a tractor, for harvesting carrots. While this method is simple and low-cost, and meets harvesting efficiency requirements, the harvested carrots are prone to breakage and damage, resulting in a low integrity rate. Summary of the Invention

[0006] The object of the present invention is to provide a carrot harvester and carrot tassel remover to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a carrot harvesting and tassel removing machine, comprising a carriage, a tilted longitudinal support frame is provided on the front side of the carriage, a tassel supporting plate B is provided on the front bottom of the longitudinal support frame, and a tassel supporting plate A fixedly connected to the carriage is provided side by side with the tassel supporting plate B, and a gap is formed between the tassel supporting plate A and the tassel supporting plate B; a transmission chain is connected to the bottom of the longitudinal support frame, and tassel leaf splints are evenly distributed on the outer wall of the transmission chain; a soil scraper and a tassel cutting assembly fixed to the carriage are provided below the side where the transmission chain moves upward, and a recycling box is provided at the bottom of the tassel cutting assembly.

[0011] Preferably, an upper support plate fixedly connected to the crane is provided above the recovery box.

[0012] Preferably, a hook is provided on the top of the inner wall of the carriage.

[0013] Preferably, the tassel cutting assembly includes a supporting baffle, a rotating cutter disc is provided on the inner side of the supporting baffle, and a replaceable cutting blade is provided on the rotating cutter disc.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This all-in-one carrot harvester and tuft remover uses a single-row chain for transmission, reducing production costs and allowing for a wider range of sizes. By installing a tuft clamp on the transmission chain as a lifting device, it provides a more secure grip than a double-row chain. The tuft clamp adjusts its grip and release by changing the angle of the clamp when the chain links turn, eliminating the need for additional drive equipment.

[0018] A tensioning pulley mechanism is installed inside the transmission chain to adjust the tightness of the transmission chain and increase the stability of the transmission chain movement. A loosening blade is installed at the bottom of the crane to improve the pulling efficiency and pulling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-12 , the present invention provides a technical solution:

[0034] A carrot harvester and carrot tufting machine includes a carriage 1, each of the carriage 1's two front wheels being equipped with a travel motor. A tilted longitudinal support frame 2 is provided on the front side of the carriage 1. A tufting plate B12 is provided at the front bottom of the longitudinal support frame 2. A tufting plate A11, fixed to the carriage 1, is provided alongside tufting plate B12. A short track for the radish tufts is formed between tufting plates A11 and B12. As the carriage 1 advances, the radish tufts enter the gap between tufting plates A11 and B12.

[0035] The bottom of the longitudinal support frame 2 is connected to a single-row transmission chain 4, and tassel splints 5 are evenly distributed on the outer wall of the transmission chain 4. The radish tassels are clamped by the tassel splints 5, and the radish is lifted up; the lower side of the transmission chain 4 moving upward is provided with a soil scraper 16, a grinding roller 9 and a tassel cutting assembly 7 fixed to the carriage 1, and a recycling box 8 is provided at the bottom of the tassel cutting assembly 7. The soil scraper 16 is set in a U shape, which is used to hang off some of the soil stuck on the radish. Then the grinding roller 9 is used to clean some of the fibrous roots on the radish. Finally, the radish and the radish tassels are separated by the tassel cutting assembly 7, the tassels are carried away, and the radish falls freely into the recycling box 8 below.

[0036] A driven gear 14 and a driving gear 15 are respectively provided at the bottom ends of the longitudinal support frame 2. A transmission chain 4 is arranged around the driven gear 14 and the driving gear 15. The driving gear 15 is connected to the motor. When the driving gear 15 drives the transmission chain 4 to rotate, the transmission chain 4 drives the tassel splint 5 to move. The tassel splint 5 clamps the radish tassels to pull out the radish, then drives the radish to move, and then throws away the radish tassels.

[0037] A tensioning pulley mechanism 3 is provided inside the transmission chain 4 to support the transmission chain 4. The tensioning pulley mechanism 3 is added to improve the stability of the transmission chain 4. Since the transmission chain 4 is subjected to a downward force when pulling radishes, the tensioning pulley mechanism 3 is used to adjust the tension of the transmission chain 4. The tensioning pulley mechanism 3 includes a cross rail 31 fixed to the bottom of the longitudinal support frame 2. A support plate 32 is provided inside the cross rail 31 to support a tensioning gear 33. The tensioning gear 33, which is meshed with the transmission chain 4, is rotatably connected to the support plate 32.

[0038] Two loosening shovels 10 are fixedly connected side by side to the bottom of the traveling vehicle 1, and the two loosening shovels 10 are respectively located at the rear sides of the tassel board A11 and the tassel board B12.

[0039] The loosening shovel 10 breaks up the soil before gripping the carrots, allowing the gripping device to successfully capture the carrots, improving picking success and harvesting efficiency. The loosening shovel 10 doesn't need to dig the carrots out of the soil; it simply reduces the soil's adhesion during extraction. Therefore, it mimics the shape of a mole's claw to achieve better soil-breaking results.

[0040] Moles are a species that live underground for a long time. They have a very strong ability to dig holes. Their front feet are large and turned outward, and their claws have very good mechanical properties, which can obtain low resistance when digging. The mole's digging process is divided into four steps: entering the soil, shearing, digging and returning. When entering the soil, the claws shear and produce a secondary shear effect on the soil, reducing the digging resistance. During the shearing process, as it gradually goes deeper, the curves on both sides of its claws further shear the soil for a second time. At this time, the soil moves upward along the claws and flows into the soil, which has the effect of reducing the digging resistance. Figure 8 The mole-like claw-like loosening shovel 10 has an upturned tip on its front, which streamlines downward and widens, then narrows upward and backward, with a mid-section that bulges forward. During excavation, soil flows backward, reducing the forward resistance of the loosening shovel 10 and achieving the desired loosening effect.

[0041] An upper supporting plate 6 fixedly connected to the crane 1 is provided above the recovery box 8 .

[0042] A hook 17 is provided at the top of the inner wall of the carriage 1 , and the hook 17 can be used to hang a tassel leaf collection bag, and the bottom of the tassel leaf collection bag can be placed on the upper support plate 6 .

[0043] The tuft cutting assembly 7 includes a support baffle 71 with a V-shaped opening on its front. As the carrots move upward, the tufts pass through the V-shaped opening, shielding the carrots. The tufts are then severed by a cutting blade 73. A rotating blade disc 72 is located on the front and inner side of the support baffle 71. The rotating blade disc 72 is connected to a motor and rotates via the motor. A replaceable cutting blade 73 is provided on the rotating blade disc 72.

[0044] Along the ascending path of the transmission chain 4, a grinding roller 9, fixed to the carriage 1, is also provided. After passing through the soil scraper 16, the roller 9 comes into contact with the grinding roller 9. The grinding roller 9 comprises a cylindrical shell 3, the diameter of which is larger at the sides than at the center, and the surface of the shell 3 is curved. The shell 3 has a strip-shaped opening 92 formed in a recessed portion of the outer wall. The carrot roots enter the shell 3 through this opening. A rotating blade roller 93 is provided inside the shell 3, which is driven by a motor to cut the roots that enter the opening 92.

[0045] There is a prefabricated connecting part 13 on each chain of the transmission chain 4, and a pad is installed on the prefabricated connecting part 13. The tassel splint 5 and the pad can clamp the radish tassels. The tassel splint 5 includes a torsion spring base 51. The torsion spring base 51 has a splint 53 rotatably connected to the outside of the torsion spring base 51, and a torsion spring 52 is arranged between the torsion spring base 51 and the splint 53.

[0046] As the transmission chain 4 moves, when the tassel cleat 5 passes the meshing point between the driven gear 14 or the driving gear 15 and the chain link, the backing plate and connector 13 change angles as the chain link bends due to the different curvatures of adjacent torsion spring bases 51. At this point, the torsion spring 52 pushes the cleat 53 to its maximum position without resistance, but the cleat 53 and the torsion spring base 51 form an angle, forming an opening between them. This tassel cleat 5 does not require an additional drive device to trigger.

[0047] One end of the driving gear 15 corresponds to the gap between the gaps between the tassel plates A11 and B12. The carrot leaves that enter the gap between the tassel plates A11 and B12 then enter the opening formed by the splint 53 and the torsion spring base 51. When the splint 53 enters the linear track of the transmission chain 4, the pad and the connector 13 will change their angles as the chain links become straight. The splint 53 fits closely with the gasket, and the torsion spring 52 pushes the splint 53, giving the carrot leaves a certain clamping force. After that, as the transmission chain 4 continues to move. After scraping, grinding, and cutting and separating, the carrot leaves continue to move along with the transmission chain 4.

[0048] When it moves to the driven gear 14, the pad and the connector 13 will change their angles again as the chain link bends, and then the clamping plate 53 and the torsion spring base 51 will form an opening shape again, and the carrot tops will lose their clamping force and fall off.

[0049] The positions of the backing plate and the connecting member 13 are fixed as the angles of the chain links are bent, thereby fixing the positions for clamping and releasing the carrot leaves.
