Description

Technical Field

[0001] The invention relates to the technical field of pickers, in particular to a small-sized picker without a cam or a guard ring. Background Art

[0002] The picker is used to pick up straw and send it backwards. Most of the existing pickers are pickers with guard rings. The spring teeth are installed on the spring tooth beam, and the spring tooth beam is installed on the slide block through the spring tooth beam bearing. The slide block can move around the cam disk and can be matched with a tractor to adapt to operations in various geographical conditions.

[0003] Patent announcement number CN115226501A discloses a square bale picker without guard ring and cam, including a connecting assembly, a picking assembly and a transmission assembly, wherein the transmission assembly is connected to the connecting assembly, the picking assembly is arranged on the transmission assembly, and the picking assembly can be driven by the transmission assembly. The patent can drive the transmission assembly well through the connecting assembly, and can make the connection between them more firm and durable; the picking assembly can pick up the crop straw on the ground well, and no guard ring and cam are required, and the gap between the picking rods can be freely adjusted, which greatly improves the picking efficiency of the picking assembly; the picking assembly can be well installed through the transmission assembly, and the picking assembly is convenient to disassemble, which improves the efficiency of later maintenance.

[0004] However, the device still has some shortcomings: the device can pick up crop straw, but during the picking process, the picker is prone to contact with stones sunk in the field and cause collision. During the high-speed rotation of the picker, it collides with the stones and causes certain damage to the picker, causing the elastic teeth of the picker to bend or the gap between the adjacent teeth to become larger, thereby affecting the picking effect of straw and other weeds.

The motor is started, and the disc limits the motor to ensure the stability of the motor during operation. The output end of the motor drives the rotating rod to rotate, and the rotating rod drives the transmission roller to rotate when the rotating rod rotates. When the transmission roller rotates, it drives the elastic teeth to rotate and hook up the straw or weeds in the field for transportation. The elastic teeth guide the weeds hooked by themselves through the combing grooves of the combing plate to prevent the weeds from flying around before the elastic teeth fall off during the rotation process; when the rotating rod rotates, it drives the transmission circular plate to rotate, and when the transmission circular plate rotates, it drives the transmission belt to promote The rotating plate is rotated, and the rotating plate drives the round rod to rotate when the rotating plate rotates, and the round rod drives the groove roller to rotate when the round rod rotates. The groove roller is installed in a dispersed manner to increase the contact points with the weeds during the rotation of the round rod and the movement. At the same time, the groove outer wall of the groove roller increases the friction for weed transportation, and the reciprocating spiral groove on the outer wall of the round rod limits the built-in block of the rejection plate when the round rod rotates, and the built-in block of the rejection plate constantly resists the inner wall of the reciprocating spiral groove, so that when the round rod rotates, the rejection plate can slide back and forth along the outer wall of the reciprocating spiral groove of the round rod under the limitation of the limiting rod, and the rejection plate slides and removes stones deeply trapped in the field soil on the movement path of the elastic teeth.

When the rejection plate slides back and forth, it drives the L-shaped rod to move synchronously. The L-shaped rod drives the sliding plate to slide synchronously along the left outer wall of the fixed plate. When the sliding plate slides away from the center of the round rod, it hits the inclined surface of the inclined plate to generate a resistance force. At this time, the hinge shaft between the inclined plate and the fixed plate starts to rotate. At this time, the inclined plate swings in an arc shape with the hinge shaft as the center. When the sliding plate is reset, the inclined plate is reset synchronously.

[0009] According to the above technical solution, the front of the sliding plate is fixedly installed on the back of the L-shaped rod, the inclined surface of the inclined plate is located on the movement track of the sliding plate, a torsion spring is arranged between the right side of the inclined plate and the left side of the fixed plate, and a root removal device for cutting the roots of field vegetation is arranged under the groove roller.

[0010] The outer wall of the sliding ring is fixedly mounted on the inner wall of the fixed plate, and the outer wall of the sliding ring is fixedly mounted on the inner wall of the fixed plate.

[0011] According to the above technical scheme, the root removal device includes an L-shaped push plate, a U-shaped plate, a sliding rod, a cutting assembly and a penetrating rod. The back of the L-shaped push plate is fixedly installed on the inner wall of the sliding plate, the outer walls of the front and back ends of the U-shaped plate are fixedly installed on the inner wall of the device body, the left and right ends of the sliding rod are slidably installed on the inner wall of the U-shaped plate, the cutting assembly penetrates inside and is fixedly installed on the outer wall of the sliding rod, and the outer wall of the penetrating rod penetrates and is fixedly installed inside the cutting assembly. When the sliding plate slides, it drives the L-shaped push plate to move synchronously, and the L-shaped push plate pushes the cutting assembly to move synchronously. During the forward and backward movement of the cutting assembly, it drives the sliding rod to slide synchronously along the inner wall of the U-shaped plate. The U-shaped plate limits the sliding rod to keep the sliding rod stable. At the same time, multiple cutting assemblies achieve synchronous movement through the limiting fixation of the penetrating rod.

[0012] According to the above technical solution, the U-shaped plate is located on the left side of the elastic tooth, the top of the cutting assembly is located inside the U-shaped plate, and the left side of the cutting assembly is fixedly installed on the right side of the L-shaped push plate.

[0013] According to the above technical scheme, the root removal device also includes an additional arc block, a U-shaped tough plate and a protective spring sheet. The left side of the additional arc block is fixedly installed on the right side of the cutting assembly, the left side of the top of the U-shaped tough plate is fixedly installed on the right side of the U-shaped plate, the bottom of the U-shaped tough plate is located on the arc surface motion trajectory on the right side of the additional arc block, and the right side of the protective spring sheet is fixedly installed on the left side of the cutting assembly. The cutting assembly drives the additional arc block to move synchronously. The additional arc block increases the thickness at the center of the cutting assembly.

The protective spring sheet relies on its own arc surface to guide and drive away the gravel on the movement path of the cutting assembly.

[0014] The present invention provides a small-sized camless and guardless pickup, which has the following beneficial effects:

[0015] (1) The present invention cooperates with a motor, a rotating rod, a transmission circular plate, a transmission roller, elastic teeth, a transmission belt, a rotating plate, a circular rod, a grooved roller, a rejecting plate and a limit rod, so that the device has better firmness than a traditional picker, and the spacing of the elastic teeth can be adjusted conveniently by relying on the mounting groove on the surface of the transmission roller, thereby improving the actual use effect; at the same time, the centrifugal force of the rotation of the grooved roller is used to improve the rolling efficiency of the weeds, and the velvet grass is transmitted to the movement path of the elastic teeth to avoid the scattered fine velvet weeds being located in the adjacent gaps of the elastic teeth and unable to be collected, thereby reducing the picking effect; at the same time, the rejecting plate prevents the elastic teeth from colliding violently with stones trapped in the field, causing the elastic teeth to bend or the adjacent gaps to become larger, thereby affecting the picking effect of weeds such as straw.

A round rod 12 is fixedly installed at the center of the inner wall of the moving plate 11, and a number of reciprocating spiral grooves are equidistantly opened on the outer wall of the round rod 12. A number of groove rollers 13 are equidistantly and fixedly installed on the outer wall of the round rod 12. A number of rejecting plates 14 are penetrated and slidably installed on the outer wall of the reciprocating spiral groove of the round rod 12, and a limit rod 15 is fixedly installed on the inner wall of the device body 1. Through the above cooperation, the device has better firmness than the traditional picker, and the installation groove on the surface of the transmission roller 8 is convenient for adjusting the spacing of the elastic teeth 9, thereby improving the actual use effect; through the above cooperation, the centrifugal force of the rotation of the groove roller 13 is relied on to improve the rolling efficiency of the weeds, and the velvet grass is transmitted to the movement path of the elastic teeth 9, so as to avoid the scattered fine velvet weeds being located in the adjacent gaps of the elastic teeth 9 and unable to be collected, resulting in reduced picking effect. At the same time, the rejecting plate 14 prevents the elastic teeth 9 from violently colliding with the stones trapped in the field, causing the elastic teeth 9 to bend or the adjacent gaps to become larger, thereby affecting the picking effect of weeds such as straw.

[0030] The rotating plate 11 is located on the left side of the transmission roller 8, and the outer wall of the rotating plate 11 is transmission-connected to the left side of the inner wall of the transmission belt 10. The plurality of rejecting plates 14 are located between the adjacent plurality of groove rollers 13. The outer wall of the limiting rod 15 movably penetrates the inside of the rejecting plate 14. A gathering device 4 is provided on the left side of the rejecting plate 14 for pushing the weeds toward the center direction of the device body 1 during the movement of the device body 1.

[0031] When in use, the device body 1 and other devices are installed on a tractor or other running equipment through the mounting frame 2, the motor 31 is started, the disc 3 limits the motor 31 to ensure the stability of the motor 31 during operation, and the output end of the motor 31 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the transmission roller 8 to rotate when it rotates, and the transmission roller 8 drives the elastic teeth 9 to rotate when it rotates. When the elastic teeth 9 rotate, the straw or weeds in the field are rotated and hooked for transportation, and the elastic teeth 9 guide the weeds hooked by themselves through the combing grooves of the combing plate 21 to prevent the weeds from flying around during the rotation process without the elastic teeth 9 falling off. Through the above cooperation, the device has better firmness than the traditional picker, and the spacing of the elastic teeth 9 can be adjusted conveniently by relying on the mounting grooves on the surface of the transmission roller 8, thereby improving the actual use effect; when the rotating rod 6 rotates, it drives the transmission circular plate 7 to rotate, and when the transmission circular plate 7 rotates, the transmission of the transmission belt 10 drives the rotating plate 11 to rotate, and when the rotating plate 11 rotates, it drives the round rod 12 to rotate, and when the round rod 12 rotates, it drives the groove roller 13 to rotate. The groove roller 13 is installed in a dispersed manner to increase the contact points between the round rod 12 and the weeds during the rotation and movement. At the same time, the outer wall of the groove of the groove roller 13 increases the friction force on the weed transportation. When the round rod 12 rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the rejection plate 14, and the built-in block of the rejection plate 14 constantly resists the inner wall of the reciprocating spiral groove, so that when the round rod 12 rotates, the rejection plate 14 can slide back and forth along the outer wall of the reciprocating spiral groove of the round rod 12 under the restriction of the limiting rod 15, and the rejection plate 14 The stones deeply embedded in the field soil on the moving path of the elastic teeth 9 are removed by sliding. The above cooperation relies on the rotating centrifugal force of the groove roller 13 to improve the rolling efficiency of the weeds, and the velvet grass is transmitted to the moving path of the elastic teeth 9 to avoid the scattered fine velvet weeds being located in the adjacent gaps of the elastic teeth 9 and unable to be collected, resulting in reduced picking effect. At the same time, the removal plate 14 prevents the elastic teeth 9 from colliding violently with the stones embedded in the field, causing the elastic teeth 9 to bend or the adjacent gaps to become larger, thereby affecting the picking effect of weeds such as straw.

[0032] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a gathering device 4;

[0033] The gathering device 4 includes an L-shaped rod 41, a fixed plate 42, a sliding plate 43 and an inclined plate 44. The right side of the L-shaped rod 41 is fixedly installed on the left side of the outer wall of the rejection plate 14, the right side of the fixed plate 42 is fixedly installed on the left side of the device body 1, the right side of the sliding plate 43 is slidably installed on the left side of the fixed plate 42, and the right side of the inclined plate 44 is hinged at the left edge of the fixed plate 42. Through the above cooperation, the weeds on the periphery of the device body 1 are gathered and pushed toward the center of the device body 1 by relying on the reciprocating swing of the inclined plate 44, that is, the picking range of the elastic teeth 9 for weeds such as straw is expanded, and the elastic teeth 9 are prompted to achieve a larger range of picking paths within the same time, shortening the working time while improving work efficiency and thus reducing cost expenditure.

[0034] The front of the sliding plate 43 is fixedly mounted on the back of the L-shaped rod 41, the inclined surface of the inclined plate 44 is located on the movement track of the sliding plate 43, a torsion spring is arranged between the right side of the inclined plate 44 and the left side of the fixed plate 42, and a root removal device 5 for cutting the roots of field vegetation is arranged under the groove roller 13.

[0035] The gathering device 4 also includes a screw rod 45, a plurality of dustproof mesh plates 46, an L-shaped limiting plate 47 and a sliding ring 48. The screw rod 45 is rotatably mounted on the inner wall of the sliding plate 43 at one end close to the inner wall of the device body 1. The plurality of dustproof mesh plates 46 are equidistantly and fixedly mounted on the outer wall surface of the screw rod 45. The back of the right end of the L-shaped limiting plate 47 is fixedly mounted on the inner wall of the fixed plate 42. The sliding ring 48 penetrates through the inside and is slidably mounted on the outer wall surface of the screw rod 45. The right side of the outer wall of the sliding ring 48 is fixedly connected to the left side of the L-shaped limiting plate 47, and the inner wall of the sliding ring 48 contacts the outer wall of the spiral groove of the screw rod 45. Through the above cooperation, the dustproof mesh plate 46 is rotated to intercept the dirt or dust raised within the weed range pushed by the inclined plate 44 and the sliding plate 43, so as to prevent the dirt from adhering to and accumulating on the outer wall of the fixed plate 42 to cause certain obstruction to the sliding path of the sliding plate 43, and to avoid the sliding frequency and sliding amplitude of the sliding plate 43 from being reduced, thereby affecting the gathering effect of the inclined plate 44 on the weeds.

[0036] When in use, the rejection plate 14 slides back and forth, driving the L-shaped rod 41 to move synchronously, and the L-shaped rod 41 drives the sliding plate 43 to slide synchronously along the left outer wall of the fixed plate 42. When the sliding plate 43 slides away from the center of the round rod 12, it contacts the inclined surface of the inclined plate 44 to generate a resistance force. At this time, the hinge shaft between the inclined plate 44 and the fixed plate 42 begins to rotate. At this time, the inclined plate 44 swings in an arc with the hinge shaft as the center. When the sliding plate 43 is reset, the inclined plate 44 is reset synchronously. Through the above cooperation, the weeds on the periphery of the device body 1 are gathered and pushed toward the center of the device body 1 by relying on the reciprocating swing of the inclined plate 44, that is, the picking range of the elastic teeth 9 for weeds such as straw is expanded, so that the elastic teeth 9 can achieve a larger range of picking paths within the same time, shortening the working time while improving the working efficiency and thus reducing the cost expenditure. When the sliding plate 43 moves toward the center of the round rod 12, it drives the screw rod 45 to move synchronously. When the outer wall of the screw rod 45 slides along the inner wall of the sliding ring 48, the L-shaped limit plate 47 limits the sliding ring 48 to keep the sliding ring 48 stationary. At this time, the internal block of the sliding ring 48 continuously contacts the non-self-locking spiral groove on the outer wall of the screw rod 45, prompting the screw rod 45 to generate a rotating force and start to rotate. The screw rod 45 drives multiple dustproof mesh plates 46 to rotate. Through the above cooperation, the dustproof mesh plates 46 rotate to intercept the dirt or dust raised within the weed range pushed by the inclined plate 44 and the sliding plate 43, so as to prevent the dirt from adhering to and accumulating on the outer wall of the fixed plate 42 to cause certain obstruction to the sliding path of the sliding plate 43, thereby avoiding the sliding frequency and sliding amplitude of the sliding plate 43 from being reduced, thereby affecting the weed gathering effect of the inclined plate 44.

[0037] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a root removal device 5;

[0038] The root removal device 5 includes an L-shaped push plate 51, a U-shaped plate 52, a sliding rod 53, a cutting assembly 54 and a penetrating rod 55. The back of the L-shaped push plate 51 is fixedly mounted on the inner wall of the sliding plate 43, the outer walls of the front and back ends of the U-shaped plate 52 are fixedly mounted on the inner wall of the device body 1, the left and right ends of the sliding rod 53 are slidably mounted on the inner wall of the U-shaped plate 52, the cutting assembly 54 penetrates inside and is fixedly mounted on the outer wall of the sliding rod 53, and the outer wall of the penetrating rod 55 penetrates and is fixedly mounted inside the cutting assembly 54. Through the above cooperation, the cutting assembly 54 is installed in a point-by-point manner to contact the field ditch and perform horizontal cutting. The cutting assembly 54 cuts the remaining plant rhizomes or weed rhizomes in the ditch to prevent the plant rhizomes or weed rhizomes from continuing to germinate and grow without treatment, which increases the preparation time for the next round of cultivation.

[0039] The U-shaped plate 52 is located on the left side of the elastic tooth 9 , the cutting assembly 54 is located above the inside of the U-shaped plate 52 , and the left side of the cutting assembly 54 is fixedly installed on the right side of the L-shaped push plate 51 .

[0040] The root removal device 5 also includes an additional arc block 56, a U-shaped tough plate 57 and a protective spring sheet 58. The left side of the additional arc block 56 is fixedly installed on the right side of the cutting component 54, the top left side of the U-shaped tough plate 57 is fixedly installed on the right side of the U-shaped plate 52, the bottom of the U-shaped tough plate 57 is located on the arc surface movement trajectory on the right side of the additional arc block 56, and the right side of the protective spring sheet 58 is fixedly installed on the left side of the cutting component 54. The above coordination can prevent the cutting component 54 from bending when the soil is turned over as the device body 1 moves left and right, and prevent wet soil from adhering to the outer wall of the cutting component 54 through vibration force, thereby reducing its cutting efficiency for roots and rhizomes, and at the same time reduce the contact frequency between the cutting component 54 and the gravel in the field gullies to avoid the blunting of the cutting component 54.

[0041] When in use, the sliding plate 43 drives the L-shaped push plate 51 to move synchronously when it slides, and the L-shaped push plate 51 pushes the cutting assembly 54 to move synchronously. During the forward and backward movement of the cutting assembly 54, the sliding rod 53 is driven to slide synchronously along the inner wall of the U-shaped plate 52, and the U-shaped plate 52 limits the sliding rod 53 to keep the sliding rod 53 stable. At the same time, multiple cutting assemblies 54 are fixed by the through rod 55 to achieve synchronous movement. Through the above cooperation, the cutting assembly 54 is installed in a point-by-point manner to contact the field ditch and perform horizontal cutting. The cutting assembly 54 cuts the remaining plant rhizomes or weed rhizomes in the ditch to prevent the plant rhizomes or weed rhizomes from continuing to germinate and grow without treatment, which increases the preparation time for the next round of cultivation; the cutting assembly 54 drives the additional arc block 56 to move synchronously, and the additional arc block 56 increases the thickness at the center of the cutting assembly 54. During the movement, the arc block 56 contacts the bottom of the U-shaped tough plate 57 to generate a resistance force. The additional arc block 56 continues to move and contacts the U-shaped tough plate 57 to bend and deform. After the additional arc block 56 passes over itself, the U-shaped tough plate 57 will swing back and forth and vibrate during the process of restoring itself through its own toughness. The transmission of force causes the cutting component 54 to vibrate synchronously. At the same time, the cutting component 54 drives the protective spring sheet 58 to move synchronously. The protective spring sheet 58 relies on its own arc surface to guide and drive away the gravel on the movement path of the cutting component 54. The above cooperation avoids the bending of the cutting component 54 when the soil is turned over as the device body 1 moves left and right, and avoids the wet soil from adhering to the outer wall of the cutting component 54 through vibration force, which reduces its cutting efficiency for roots and rhizomes. At the same time, the contact frequency between the cutting component 54 and the gravel in the gullies in the field is reduced to avoid the blunting of the cutting component 54.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
