Description

Technical Field

[0001] This utility model relates to hay-raking equipment, specifically to hay rakes and hay balers. Background Technology

[0002] Existing finger-wheel hay rakes are generally wide, capable of gathering a large area of ​​hay or residual film at once, effectively improving hay-raking efficiency. However, the large width of the equipment also leads to problems such as difficulty in transporting and moving the hay rake when not in operation. In addition, due to the variable ground and surrounding environment during hay-raking operations, the height and flatness of the rake wheels of existing finger-wheel hay rakes are either not adjustable or inconvenient to adjust. The hay rakes cannot quickly and timely adjust to the ground and surrounding environment conditions, which to some extent affects the hay-raking effect and efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hay rake that can be folded up when not in use, and the hay rake wheel plane and hay rake wheel height can be adjusted according to the situation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a hay rake, including a frame, a tilting frame, a tilting drive, and a hay rake mechanism. Two tilting connecting parts are symmetrically arranged on the frame, and the two tilting frames are respectively connected to the two tilting connecting parts. Each tilting frame is driven by the tilting drive to tilt up and down relative to the frame between a folded position and a working position. A hay rake mechanism is provided on the tilting frame, which includes a hay rake beam and hay rake wheels. The hay rake beam is connected to the tilting frame and can rotate and adjust relative to the tilting frame. At least one hay rake wheel is distributed along the length of the hay rake beam. The hay rake mechanism is provided on the tilting frame, which is connected to the frame and is driven by the tilting drive to tilt up and down relative to the frame. When the tilting frame is in the working position, the hay rake mechanism is in the working state; when the tilting frame is folded to the folded position, the hay rake mechanism is in the folded-up state.

[0005] As an optional technical solution of this utility model, the flipping drive includes two first telescopic members. The first telescopic members are connected to the frame and rotate up and down relative to the frame. The telescopic part of the first telescopic member is connected to the flipping frame and rotates relative to the flipping frame.

[0006] As an optional technical solution of this utility model, two flipping connectors are symmetrically arranged on the frame. The flipping connectors include a connecting shaft and a connecting sleeve. The connecting shaft is connected to the frame and is parallel to the flipping axis of the flipping frame. The connecting sleeve is arranged on the connecting shaft and rotates around the connecting shaft.

[0007] The hay-raking mechanism also includes a second telescopic component. One end of the second telescopic component is connected to the connecting sleeve and rotates relative to the connecting sleeve. The other end of the second telescopic component is connected to the hay-raking beam. The second telescopic component rotates relative to the hay-raking beam and drives the hay-raking beam to rotate relative to the turning frame for adjustment. The angle of the hay-raking beam and the deflection angle of each hay-raking wheel plane can be adjusted through the second telescopic component, thereby adjusting the included angle between the two hay-raking mechanisms and adjusting the size and width of the hay-raking area.

[0008] As an optional technical solution of this utility model, the end of the second telescopic member is provided with a joint bearing, and the second telescopic member is connected to the hay rake beam through the joint bearing.

The third telescopic member is disposed on the hay-raking beam, and its telescopic part is rotatably connected to the adjustment link. The third telescopic member drives each mounting member to rotate up and down relative to the hay-raking beam, thereby adjusting the height of each hay-raking wheel. By installing the adjustment assembly, the height of each hay-raking wheel on the hay-raking beam can be adjusted simultaneously, ensuring that the hay-raking wheels are at a suitable working height.

[0010] As an optional technical solution of this utility model, the adjusting connection part is an elastic telescopic rod, and the adjusting connection part is rotatably connected to the mounting rod and the adjusting link.

The hay rake beam is connected to the connecting arm and can rotate and adjust relative to the connecting arm.

[0013] And / or, the front end and / or rear end of the frame are provided with a traction connection part, which rotates up and down relative to the frame.

[0014] Based on the same concept, this utility model also provides a hay baling machine, including a picking mechanism, a baling mechanism and the aforementioned hay rake. The hay rake is set in front of the picking mechanism and gathers the hay into the picking area of ​​the picking mechanism. The picking mechanism picks up the hay and conveys it to the baling mechanism for baling.

[0015] The rake's frame is equipped with a drive shaft, which has a power receiving unit and a power output unit.

The elevator includes a belt conveyor, and a discharge port is provided on the conveying surface of the belt conveyor. The discharge port on the conveying surface of the elevator allows impurities such as soil and stones mixed in with the grass to be discharged during the transport process.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. The two raking mechanisms of the hay rake are foldable to reduce space occupation during transportation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-4 The hay rake includes a frame 11, a tilting frame 12, a tilting drive 13, and a hay rake mechanism 1. The frame 11 is provided with two tilting connection parts, which are symmetrically arranged and located on the left and right sides of the frame 11 respectively. There are two tilting frames 12, which are connected to the two tilting connection parts respectively. The two tilting frames 12 are driven by the tilting drive 13 to tilt up and down relative to the frame 11. Each tilting frame 12 is provided with a hay rake mechanism 1. When the tilting frame 12 tilts down relative to the frame 11 until the hay rake mechanism 1 is at a suitable height for hay rakeing, the tilting frame 12 is in the working position. When the tilting frame 12 tilts up relative to the frame 11 until the hay rake mechanism 1 is folded and placed on the frame 11, the tilting frame 12 is in the folded position.

[0029] For details, please refer to Figure 1 and Figure 4 The frame 11 is equipped with wheels, and a traction connection 112 is provided at the front and / or rear ends of the frame 11. When the traction connection 112 is provided at the front end of the frame 11, it can be used to connect the frame 11 to a towing vehicle such as a tractor. When the traction connection 112 is provided at the rear end of the frame 11, it can be used to connect the frame 11 to working equipment such as a pickup machine or a baler. The traction connection 112 is connected to the frame 11 and can rotate up and down around the frame 11, so that the frame 11 can adapt to various road conditions when being towed and / or towing working equipment such as balers.

[0030] Please see Figure 1 and Figure 2 The flipping connection includes an ear plate fixed to the frame 11, with ear holes on the ear plate. A flipping shaft is provided on the flipping frame 12, and the flipping shaft passes through the ear holes to connect the flipping frame 12 to the flipping connection. The flipping frame 12 can rotate around the flipping shaft, thereby flipping up and down relative to the frame 11. The flipping connection can also be in the form of a bearing seat.

[0031] Please see 1 and Figure 4 The tilting drive component 13 includes two first telescopic components. The first telescopic component is preferably a hydraulic cylinder so that when the hay rake 1 is connected to a tractor or other tractor, the first telescopic component can be connected to the hydraulic control system of the tractor. The first telescopic component is connected to the frame 11 and rotates up and down relative to the frame 11. The telescopic part of the first telescopic component is connected to the tilting frame 12 and the first telescopic component can rotate relative to the tilting frame 12. The telescopic movement of the first telescopic component can drive the corresponding tilting frame 12 to tilt up and down around the frame 11.

[0032] Please see Figures 1-4 The hay rake mechanism 1 includes a rake beam 141 and rake wheels 142. At least one rake wheel 142 is distributed along the length of the rake beam 141. The rake wheels 142 adopt existing finger-wheel or similar forms. When there is more than one rake wheel 142, the wheel planes of each rake wheel 142 on the rake beam 141 are parallel to each other. When each turning frame 12 is in the working position, the rake beams 141 of the two hay rake mechanisms 1 form a certain angle. The area between the two rows of rake wheels 142 is the rake zone. The rake beam 141 is connected to the corresponding turning frame 12, and the rake beam 141 can rotate and adjust relative to the turning frame 12, making the angle between the two rake beams 141 adjustable, thereby making the range and width of the rake zone adjustable.

[0033] Please see Figure 2In a further embodiment, the tilting frame 12 is provided with mounting holes. When the tilting frame 12 is in the working position, the mounting holes are along the width direction of the machine body. A connecting arm 121 is provided in the mounting holes, and the connecting arm 121 passes through the mounting holes and can be adjusted along the mounting holes. As a specific example, the tilting frame 12 is provided with a first through hole corresponding to the mounting hole, and the first through hole communicates with the mounting hole. The connecting arm 121 is provided with several second through holes along its length direction. When the connecting arm 121 moves along the mounting holes and the first through hole aligns with a certain second through hole, a mounting pin is used to install and fix the connecting arm 121 onto the mounting frame through the first through hole and the second through hole. The hay rake beam 141 is connected to the connecting arm 121 and rotates around the connection point with the connecting arm 121, thereby realizing the adjustment of the included angle between the two hay rake beams 141. The connecting arm 121 can be adjusted along the mounting holes so that the installation distance between the two hay rake beams 141 can be adjusted, thereby enabling a wider range of adjustment of the hay rake area.

[0034] The frame 11 is also provided with two flipping connectors 111, which are symmetrically arranged and located on the left and right sides of the frame 11 respectively. Each flipping connector 111 includes a connecting shaft and a connecting sleeve. The connecting shaft is connected to the frame 11 and is parallel to the flipping axis of the flipping frame 12 relative to the frame 11. The connecting sleeve is provided on the connecting shaft and can rotate around the connecting shaft. The hay rake 1 mechanism also includes a second telescopic member 143, which is a telescopic rod. One end of the second telescopic member 143 is connected to the connecting sleeve and can rotate relative to the connecting sleeve. The axis of rotation of the second telescopic member 143 relative to the connecting sleeve is perpendicular to the axis of rotation of the connecting sleeve. Alternatively, the second telescopic member 143 is connected to the connecting sleeve through a spherical bearing. The other end of the second telescopic member 143 is connected to the hay rake beam 141 and can rotate relative to the hay rake beam 141. In a preferred embodiment, the end of the second telescopic member 143 is provided with a spherical bearing, and the second telescopic member 143 is connected to the hay rake beam 141 through a spherical bearing. The extension and retraction of the second telescopic member 143 can cause the rake beam 141 to rotate relative to the tilting frame 12 or the connecting arm 121, thereby adjusting the included angle between the two rake beams 141. Furthermore, due to the tilting connecting member 111, while the tilting frame 12 causes the rake mechanism 1 to tilt up and down relative to the frame 11, the second telescopic member 143 can also adaptively tilt and move in accordance with the positional changes of the rake mechanism 1. When the connecting arm 121 moves and adjusts relative to the tilting frame 12 along the mounting hole, the length of the second telescopic member 143 is adaptively adjusted to adjust the included angle between the two rake mechanisms 1.

[0035] Please see Figure 3In a preferred embodiment, the hay rake 1 further includes an installation and adjustment mechanism for adjusting the height of each hay rake wheel 142. The installation and adjustment mechanism includes a third telescopic member 144, an adjustment link 145, and an installation rod 146. At least one installation rod 146 is provided along the length of the hay rake beam 141. The installation rod 146 is used to install the hay rake wheels 142 and adjust the height of the hay rake wheels 142. The installation rod 146 is rotatably connected to the hay rake beam 141 and can rotate up and down relative to the hay rake beam 141. When the installation rod 146 is provided with the hay rake wheels 142 and rotates up and down relative to the hay rake beam 141, it can drive the hay rake wheels 142 to rise or fall. In order to reduce space occupation, the installation rod 146 is designed as a U-shape, and the hay rake wheels 142 are installed at the lower end of the installation rod 146.

[0036] The mounting rod 146 is also provided with an adjustment connection part 147. Each adjustment connection part 147 is connected to an adjustment link 145. The adjustment link 145 is rotatably connected to each adjustment connection part 147. By moving the adjustment link 145, each mounting rod 146 can be rotated up and down relative to the hay rake beam 141 through each adjustment connection part 147, thereby simultaneously adjusting the height of multiple hay rake wheels 142. The third telescopic member 144 is preferably a hydraulic control system cylinder suitable for connection to the traction vehicle. The third telescopic member 144 is set on the hay rake beam 141. The telescopic part of the third telescopic member 144 is connected to the adjustment link 145, and the adjustment link 145 can rotate relative to the third telescopic member 144. The third telescopic member 144 drives the adjustment link 145 to move, thereby adjusting the height of each hay rake wheel 142.

[0037] Furthermore, the adjusting connection 147 is an elastic telescopic rod. One end of the adjusting connection 147 is connected to the mounting rod 146 and can rotate relative to the mounting rod 146. The other end of the adjusting connection 147 is connected to the adjusting connecting rod 145 and can rotate relative to the adjusting connecting rod 145. By utilizing the elasticity of the adjusting connection 147, during the raking process, each raking wheel 142 can adaptively adjust its height to a certain extent according to changes in terrain.

[0038] As a further embodiment, the installation and adjustment assembly also includes a mounting base 148, a support plate, and a connecting plate. A mounting base 148 is provided on the hay rake 141 corresponding to each mounting rod 146. The mounting base 148 is connected to the hay rake 141. The mounting rod 146 is connected to the mounting base 148 and rotates up and down relative to the mounting base 148. A support plate is provided on the mounting base 148. The connecting plate is connected to the support plate and rotates up and down relative to the support plate. The support plate is also connected to the adjusting connecting rod 145 and rotates up and down relative to the adjusting connecting rod 145. The support plate and the connecting plate cooperate to support and limit the adjusting connecting rod 145. Preferably, the connection position between the adjusting connecting rod 145 and the adjusting connecting part 147 and the connection position between the adjusting connecting rod 145 and the connecting plate are at the same location. The rotation axis of the adjusting connecting part 147 relative to the adjusting connecting rod 145 coincides with the rotation axis of the connecting plate relative to the adjusting connecting rod 145.

[0039] Please refer to it again. Figures 1-4 In this embodiment, when the hay rake 1 is performing hay rakeing operations, the frame 11 is connected to the traction vehicle. The tilting drive 13 drives the two tilting frames 12 to rotate to the working position, so that the hay rake wheels 142 of the two hay rake 1 structures contact the ground. As the traction vehicle moves the frame 11, the hay rake wheels 142 rotate due to friction with the ground, gathering the hay into the hay rake area. The size of the hay rake area can be adjusted by adjusting the position of the connecting arm 121 relative to the tilting frame 12 and by adjusting the angle of the hay rake beam 141 through the second telescopic member 143. The maximum working width of the hay rake 1 can also be adjusted. The height of each hay rake wheel 142 on the hay rake beam 141 can be adjusted through the third telescopic member 144 to keep the hay rake 1 structure at the optimal working height. When the hay rake 1 needs to be transported after operation, the tilting drive 13 drives the two tilting frames 12 to rotate to the folding position. At this time, the two hay rake 1 structures are flipped up above the frame 11, and the overall width of the hay rake 1 becomes smaller.

[0043] In a preferred embodiment, the transmission system of the picking mechanism 2 is connected to the transmission system of the packing mechanism 3, and the power output part of the transmission shaft 113 is connected to the transmission system of the picking mechanism 2. The transmission shaft 113 transmits the power received from the traction vehicle to the picking mechanism 2 and drives the picking mechanism 2 to pick up, while the picking mechanism 2 distributes the power to the packing mechanism 3 and drives the packing mechanism 3 to complete the packing operation.

[0044] The picking mechanism 2 includes a picking housing, a picking device 21, and a conveyor 22. The baling mechanism 3 adopts existing hay baling equipment. The structure of the baling mechanism 3 will not be described in detail here. The picking housing is connected to the baling mechanism 3.

The receiving end of the conveyor 22 is located in the throwing area of ​​the picking device 21, and the discharge end of the conveyor 22 is located in the feeding chamber of the baling mechanism 3. After picking up the hay, the picking device 21 throws it onto the conveyor 22, and the conveyor 22 transports the hay into the feeding chamber of the baling mechanism 3.

[0045] In some embodiments, the elevator 22 includes a belt conveyor with a discharge port on its conveying surface. During transport, soil and other debris mixed in with the grass are discharged from the discharge port. In other embodiments, the elevator 22 includes two belt conveyors, which are respectively installed on opposite inner walls of the pickup housing. The conveyor belts of the two belt conveyors are positioned opposite each other and are connected by several connecting rods. The gaps between adjacent connecting rods form discharge ports.

[0046] The transmission system of the picking mechanism 2 includes a gearbox, which is mounted on the picking machine housing. The gearbox has one power input end and two power output ends.
