Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically, it relates to a pick-up device without a protective ring. Background Technology

[0002] In agricultural production, straw balers are key equipment for the recycling and utilization of crop straw, and the picking device, as the core component of the baler, directly affects the efficiency and integrity of straw picking and the stability of subsequent baling operations.

[0003] Existing picking devices are mainly divided into two categories: picking devices with protective rings and picking devices without protective rings. Picking devices with protective rings are the most widely used traditional structure in the industry. They can limit the material picking range and prevent materials from splashing to both sides under the action of high-speed rotating picking mechanism. They also protect the picking mechanism and prevent foreign objects from entering and damaging the internal components. However, picking devices with protective rings are bulky. The protective ring increases the overall weight and volume of the equipment, and the picking efficiency is limited. The obstruction effect of the protective ring can hinder the contact between the material and the picking mechanism. For large or loose materials, jamming and blockage are likely to occur, requiring frequent shutdowns for cleaning. They also have poor adaptability. The fixed-size protective ring cannot be compatible with materials of different particle sizes and shapes. When changing the working scene, the corresponding protective ring must be replaced, resulting in insufficient versatility.

[0004] Currently, the existing pickup device's intermediate support structure is too long and therefore lacks strength. It is easily squeezed and deformed when encountering hard objects, affecting the normal operation of the pickup device.

[0005] Chinese patent application CN202210798857.7 discloses a square-shaped straw-collecting device without a protective ring or cam, comprising a connecting component, a collecting component, and a transmission component. The transmission component is connected to the connecting component, and the collecting component is mounted on the transmission component to drive the collecting component. This invention effectively drives the transmission component through the connecting component, resulting in a more robust and durable connection. The collecting component efficiently collects crop straw from the ground without the need for a protective ring or cam, and allows for free adjustment of the gap between the collecting rods, significantly improving the collecting efficiency. The transmission component facilitates easy installation and disassembly of the collecting component, improving the efficiency of future maintenance. However, the patent uses multiple mounting rods for the middle support. Since these mounting rods have no internal support, they will deform during use, affecting the normal operation of the pickup. In addition, the mounting rods require high assembly precision, which increases the processing difficulty and cost. Utility Model Content

[0006] The main technical problem to be solved by this utility model is to provide a pick-up device without a protective ring that has a simple overall structure, can enhance the overall strength of the picking device, is easy to assemble and disassemble, and improves the performance of the device.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A ringless pickup device includes a rotating shaft with fixed disks fixedly installed near both ends. Multiple support plates are evenly spaced on the outer surface of the rotating shaft between the two fixed disks. The multiple support plates are pentagonal. Multiple ring-shaped mounting rods are inserted between the two fixed disks. The multiple mounting rods contact the support plates simultaneously. Each mounting rod has multiple sets of pickup components linearly arrayed on it. The multiple mounting rods are connected to each other through an external protective plate.

[0008] The following are further optimizations of the above technical solution by this utility model: The fixing plate has multiple square slots arranged in a circular array near the edge of the fixing plate, and the number of square slots corresponds to the number of mounting rods.

[0009] Further optimization: The mounting rod includes a base plate inserted into two fixed plates. Both ends of the base plate are provided with protrusions. The outer dimensions of the protrusions match the square grooves. The base plate is provided with multiple third threaded mounting holes in a linear array. The number of third threaded mounting holes matches the number of picking components.

[0010] Further optimization: A first upright plate is fixedly installed on one side of the base plate, and the first upright plate is set at an angle of 90-95° with the base plate.

[0011] Further optimization: A connecting plate is fixedly installed on the other side of the first upright plate. The connecting plate and the first upright plate are set at an angle of 95-98°. The connecting plate is provided with multiple second threaded mounting holes arranged in a linear array.

[0012] Further optimization: The connection between the connecting plate and the first upright plate is provided with multiple slots arranged in a linear array.

[0013] Further optimization: A second vertical plate is vertically arranged on the other side of the base plate. On the side of the second vertical plate away from the first vertical plate, near the upper end, a plurality of connecting blocks arranged in a linear array are fixedly installed. The connecting blocks are provided with first threaded mounting holes.

[0014] Further optimization: The outer protective plate is set to an arc shape, and multiple plugs are fixedly connected to one side of the outer protective plate. The external dimensions of the plugs match the slots.

[0015] Further optimization: A first waist hole is provided on the outer protective plate at the position corresponding to the first threaded mounting hole on the connecting block, and a second waist hole is provided on the outer protective plate at the position corresponding to the second threaded mounting hole.

[0016] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It can enhance the overall structural strength of the picking device during the use of the picking device, simplify the disassembly and assembly process, improve adaptability and operation efficiency, and reduce the cost of use and maintenance.

[0017] First, a pentagonal support plate is added between the rotating shaft and the fixed plate, and multiple mounting rods are in close contact with the support plate to form a multi-point support structure. This solves the problem of easy deformation of the middle support in traditional devices and ensures stable operation of the equipment. The mounting rods are connected to the square groove of the fixed plate through protrusions. With the double fixation of the external guard plate, the overall rigidity is further enhanced, which can resist the impact of hard objects and extend the service life.

[0018] Secondly, the mounting rod adopts a modular design, which allows for quick positioning and insertion through protrusions and square slots. The pickup components and external protective plates are installed through threaded connections or insert blocks, eliminating the need for high-precision assembly and reducing operational difficulty.

[0019] In addition, the traditional guard ring design avoids the problems of material jamming and blockage caused by the guard ring. It is suitable for various forms of materials such as large pieces and loose materials. There is no need to change the guard ring according to the operation scenario, which makes it more versatile. The outer guard plate is arc-shaped and forms a reasonable picking area with the mounting rod. It prevents grass and materials from entering the inside of the device, and does not hinder the contact between the material and the picking component, thus improving picking efficiency and material integrity.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] like Figure 1-5 As shown: A ringless pickup device includes a rotating shaft 1. Fixed disks 2 are fixedly installed near both ends of the rotating shaft 1. Multiple support plates 4 are evenly spaced on the outer surface of the rotating shaft 1 between the two fixed disks 2. The multiple support plates 4 are pentagonal. Multiple ring-shaped mounting rods 5 are inserted between the two fixed disks 2. The multiple mounting rods 5 are in contact with the support plates 4 at the same time. Multiple pickup components 6 are linearly arrayed on each mounting rod 5. The multiple mounting rods 5 are connected by an external protective plate 7.

[0024] The rotating shaft 1 is fixedly connected to the drive sprocket of the baler via a spline connection, and then positioned by a bearing seat to achieve smooth torque transmission. The specific connection method is known in the prior art and will not be described in detail here.

[0025] On the opposite sides of the two fixed plates 2, a blocking pipe 3 is fixedly installed. The blocking pipe 3 can protect the area between the fixed plate 2 and the mounting bracket of the picking device on the baler, and prevent the picking device from getting tangled in straw on the rotating shaft 1 during operation.

[0026] The fixed plate 2 has multiple square grooves 21 arranged in a circular array near the edge of the fixed plate 2. The number of square grooves 21 corresponds to the number of mounting rods 5.

[0027] like Figure 5 As shown, the mounting rod 5 includes a base plate 51 that is inserted into two fixed plates 2.

[0028] Both ends of the base plate 51 are provided with protrusions 511, and the outer dimensions of the protrusions 511 match the square grooves 21. This design allows the protrusions 511 at both ends of the base plate 51 to be inserted into the corresponding square grooves 21, which facilitates installation.

[0029] The base plate 51 has a plurality of third threaded mounting holes 512 arranged in a linear array, and the number of the third threaded mounting holes 512 matches the number of the pickup components 6.

[0030] The pickup assembly 6 is detachably mounted on the corresponding third threaded mounting hole 512 by means of bolts and nuts.

[0031] A first upright plate 52 is fixedly installed on one side of the base plate 51. The first upright plate 52 and the base plate 51 are set at a 95° angle. This design makes it easy for the first upright plate 52 to be inserted into the outer protective plate 7.

[0032] A connecting plate 54 is fixedly installed on the other side of the first upright plate 52, and the connecting plate 54 and the first upright plate 52 are set at an angle of 98°.

[0033] The connecting plate 54 has a plurality of second threaded mounting holes 541 arranged in a linear array.

[0034] The connection between the connecting plate 54 and the first upright plate 52 is provided with a plurality of slots 55 arranged in a linear array.

[0035] A second vertical plate 53 is arranged vertically on the other side of the base plate 51.

[0036] A plurality of connecting blocks 531 arranged in a linear array are fixedly installed on the side of the second upright plate 53 away from the first upright plate 52 near the upper end.

[0037] The connecting block 531 and the second upright plate 53 are set at an acute angle to facilitate the fixing of the outer protective plate 7.

[0038] The connecting block 531 has a first threaded mounting hole.

[0039] like Figure 3 As shown, in this embodiment, the number of mounting rods 5 is set to five. When the five mounting rods 5 are inserted into the two fixed plates 2, the five base plates 51 respectively contact one side of the multiple pentagonal support plates 4. This design can enhance the overall strength of the mounting rods 5. At the same time, the surfaces of the five connecting plates 54 and the multiple connecting blocks 531 form a cylindrical surface, and the outer protective plate 7 is installed between the two mounting rods 5.

[0040] like Figure 4 As shown, the outer protective plate 7 is arc-shaped, and a plurality of inserts 71 are fixedly connected to one side of the outer protective plate 7. The external dimensions of the inserts 71 match those of the slots 55.

[0041] The outer protective plate 7 has a first waist hole 72 at a position corresponding to the first threaded mounting hole on the connecting block 531.

[0042] The outer protective plate 7 is provided with a second waist hole 73 at a position corresponding to the second threaded mounting hole 541.

[0043] With this design, when installing the outer protective plate 7, first insert the insert block 71 into the corresponding slot 55, then connect the second waist hole 73 to the corresponding second threaded mounting hole 541 with bolts, and connect the first waist hole 72 to the corresponding first threaded hole with bolts to complete the installation of the outer protective plate 7 and the mounting rod 5. The whole process is simple to install and the strength is increased.

[0044] With this design, the adjacent insert 71 and the mounting rod 5 together form the picking and mounting area. The picking component 6 is installed in this area. During the picking process, the outer protective plate 7 plays a protective role to prevent the picked grass from entering the device.

[0045] In this embodiment, the picking component 6 is mounted on the corresponding third threaded mounting hole 512 by bolts using spiral-shaped spring teeth. This structure and picking principle are well known in the prior art and will not be described in detail here.

[0046] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
