Description

Technical Field

[0001] The utility model belongs to the technical field of crop harvesting machinery, and specifically relates to a picking device for a baler. Background Art

[0002] The baler pick-up device uses the rotation of the rotating shaft to rotate the spring teeth, flipping the straw on the ground upwards to the auger part to achieve baling. In order to prevent the straw from getting entangled when the rotating shaft rotates, it is necessary to install a guard ring on the outside of the pick-up device to increase the winding radius of the straw, which can effectively prevent the straw from getting entangled.

[0003] In the Chinese utility model patent application number 201510553803.4, a picking and harvesting platform, a picking and harvesting system and a harvester are proposed. The picking device in the patent mainly has the following problems: first, the spring tooth beam inside the picking device is an integral structure, so the length of the spring tooth beam is relatively long. If it encounters hard objects such as stones during operation, it is easy to be squeezed and deformed by the hard objects; second, the spring tooth beam is guided by a single-sided track, which makes the rotation stability of the spring tooth beam poor. If it encounters hard objects such as stones, it is very easy for the rotation trajectory to deviate and deform. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a picking device for a baler, which adopts a segmented picking structure and a double-sided guide rail structure, solves the problem that the picking device is easy to deform, and improves the stability and picking efficiency of the picking device.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A picking device for a baler comprises a picking spindle, at least five segmented picking assemblies are arranged around the outer side of the picking spindle, a large guard ring is arranged around the outer side of the segmented picking assembly, a guard cover is fixed to each end of the large guard ring, both ends of the picking spindle are rotatably mounted on the corresponding guard covers, and each guard cover is provided with a guide rail structure for stably guiding the segmented picking assembly.

[0007] The following is a further optimization of the above technical solution by the utility model:

[0008] The segmented picking assembly includes a pair of spring-tooth beams, a first support plate is fixed in the middle of the picking spindle, a second support plate is fixed at both ends of the picking spindle, a spring-tooth beam is arranged between each second support plate and the first support plate, one end of each spring-tooth beam is rotatably mounted on the first support plate through a first bearing seat, and the other end of each spring-tooth beam is rotatably mounted on the second support plate, and a plurality of spring teeth arranged at intervals are fixed on each spring-tooth beam.

[0009] Further optimization: the guide rail structure includes an annular track arranged on the inner wall of the shield, and each second support plate is fixedly mounted with a plurality of second bearing seats, the number and position of the second bearing seats are matched with the number and position of the spring tooth beams, and each second bearing seat is rotatably mounted with an axle rod, one end of each axle rod is fixed to the corresponding spring tooth beam, and the other end of each axle rod is fixed with a connecting plate, and a guide wheel is rotatably mounted on the connecting plate, and each guide wheel is arranged in the corresponding annular track.

[0010] Further optimization: a plurality of slots are provided on the side walls of the first support plate and the second support plate, the positions and number of the slots are matched with the number and positions of the spring tooth beams, each of the first bearing seat and the second bearing seat is fixed at the corresponding slot, and each shaft rod passes through the corresponding slot.

[0011] Further optimization: the large guard ring includes a guard ring beam, which extends along the axial direction of the picking spindle. The two ends of the guard ring beam are respectively fixed on the corresponding guard covers. A number of guard strips arranged in sequence are arranged between the two guard covers. One end of each guard strip is fixedly installed on the top of the guard ring beam, and the other end of each guard strip is fixedly installed on the bottom of the guard ring beam. A picking gap is formed between each adjacent guard strip, and both ends of each spring tooth extend out of the corresponding picking gap.

[0012] Further optimization: a plurality of reinforcing plates are fixed between the two side walls of the first support plate and the picking spindle.

[0013] The utility model adopts the above technical solution and has the following beneficial effects: the technical solution of the utility model is ingenious in conception and reasonable in structure, and adopts a segmented picking structure, dividing the integral spring tooth beam into two sections and installing them separately. The segmented picking assembly has multiple supporting and fixing points, which improves the stability of the segmented picking assembly.

[0014] When the spring tooth beam encounters a hard object such as a stone, it can be rotated to avoid it, thereby preventing the spring tooth beam or the spring teeth from being bent or even broken by the hard object, thereby solving the problem of easy deformation of the picking device and improving the stability of the picking device.

[0015] Moreover, when one section of the spring-tooth beam rotates after being hit, it will not affect the picking operation of another section of the spring-tooth beam, thereby improving the efficiency of the picking work.

[0017] The utility model adopts a double-sided guide rail stabilizing structure, which makes the rotation of the segmented picking assembly more stable, and at the same time increases the supporting position of the picking spindle to the spring-tooth beam, thereby enhancing the stability of the spring-tooth beam and avoiding the deviation of the rotation of the spring-tooth beam, thereby solving the problem of possible deformation of the picking trajectory of the spring-tooth beam.

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 6 As shown together, a picking device for a baler includes a picking spindle 1. At least five segmented picking assemblies 2 are arranged around the outer side of the picking spindle 1. A large guard ring 3 is arranged around the outer side of the segmented picking assembly 2. A guard 4 is fixed to each end of the large guard ring 3. Both ends of the picking spindle 1 are rotatably mounted on the corresponding guard shrouds 4. Each guard shroud 4 is provided with a guide rail structure 5 for stably guiding the segmented picking assembly 2.

[0027] like Figure 1-Figure 4As shown together, the segmented picking assembly 2 includes a pair of spring-tooth beams 21, a first support plate 11 is fixed to the middle of the picking spindle 1, and a second support plate 12 is fixed to both ends of the picking spindle 1, and a spring-tooth beam 21 is arranged between each second support plate 12 and the first support plate 11, and one end of each spring-tooth beam 21 is rotatably mounted on the first support plate 11 through a first bearing seat 22, and the other end of each spring-tooth beam 21 is rotatably mounted on the second support plate 12, and a plurality of spring teeth 23 arranged at intervals are fixed to each spring-tooth beam 21.

[0028] In this embodiment, the two-stage spring-tooth beam 21 increases the supporting position of the picking spindle 1 to the spring-tooth beam 21 while ensuring the quality of the picking work, thereby improving the stability of the spring-tooth beam 21 and preventing the spring-tooth beam 21 from being squeezed and deformed by hard objects such as stones.

[0029] At the same time, the two sections of the spring tooth beam 21 are independently arranged and can rotate separately according to the terrain. When one section of the spring tooth beam 21 encounters a hard object such as a stone, only the spring tooth beam 21 rotates, while the other section of the spring tooth beam 21 remains in the picking state, thereby ensuring the efficiency of the picking work.

[0030] like Figure 2 , Figure 5 and Figure 6 As shown together, the guide rail structure 5 includes an annular track 51 arranged on the inner wall of the shield 4, and a plurality of second bearing seats 52 are fixedly installed on each second support plate 12, and the number and position of the second bearing seats 52 are adapted to the number and position of the spring-tooth beams 21, and a shaft rod 53 is rotatably installed on each second bearing seat 52, and one end of each shaft rod 53 is fixed to the corresponding spring-tooth beam 21, and a connecting plate 54 is fixed to the other end of each shaft rod 53, and a guide wheel 55 is rotatably installed on the connecting plate 54, and each guide wheel 55 is arranged in the corresponding annular track 51.

[0031] In this embodiment, each guide wheel 55 may adopt a bearing.

[0032] Compared with the single-sided guide rail structure in the traditional picker, the utility model adopts a double-sided guide rail structure, which enhances the supporting stability of the large guard ring 3 to the segmented picking assembly 2, and also avoids the deviation and deformation of the rotating picking trajectory of the spring tooth beam 21, thereby improving the rotation stability and picking smoothness of the spring tooth beam 21.

[0033] like Figure 3 and Figure 4 As shown together, a plurality of slots 13 are provided on the side walls of the first support plate 11 and the second support plate 12, the positions and number of the slots 13 are adapted to the number and positions of the spring tooth beams 21, each of the first bearing seat 22 and the second bearing seat 52 is fixed at the corresponding slot 13, and each shaft rod 53 passes through the corresponding slot 13.

[0034] like Figure 1 As shown, the large guard ring 3 includes a guard ring beam 31, which extends along the axial direction of the picking spindle 1. The two ends of the guard ring beam 31 are respectively fixed on the corresponding guard shields 4. A plurality of guard strips 32 arranged in sequence are arranged between the two guard shields 4. One end of each guard strip 32 is fixedly installed on the top of the guard ring beam 31, and the other end of each guard strip 32 is fixedly installed on the bottom of the guard ring beam 31. A picking gap 33 is formed between each adjacent guard strip 32, and both ends of each spring tooth 23 extend out of the corresponding picking gap 33.

[0035] In this embodiment, at least five segmented picking components 2 are arranged on the outside of the picking main shaft 1, and a large-diameter protective strip 32 is used to wrap and protect it, so as to prevent weeds, plastic films and other debris from being entangled on the spring-tooth beam 21 and affecting the picking work.

[0036] In this embodiment, the large retaining ring 3 with a large diameter speeds up the picking efficiency and makes the picking work simpler and faster.

[0037] like Figure 2 and Figure 3 As shown together, a plurality of reinforcing plates 14 are fixed between the two side walls of the first supporting plate 11 and the picking spindle 1 .

[0038] In this embodiment, the provision of the reinforcing plate 14 serves to increase the supporting strength of the first supporting plate 11 on the spring-tooth beam 21 .

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
