Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery production technology, and in particular relates to a crop collection device for use in grain drying yards. Background Technology

[0002] Grain harvesting at the threshing grounds currently relies mainly on manual labor, which involves a large workload and high labor intensity.

[0003] On the other hand, when using large agricultural implements to pile small-particle crops in some large drying yards, the drying yards are generally dome-shaped structures, and there is a large gap between the implements and the ground. This requires the implements to be moved back and forth to pile the grain, resulting in low piling efficiency. Summary of the Invention

[0004] To address the shortcomings and problems existing in the aforementioned background technology, the present invention provides a crop collection device applied to grain drying yards, specifically implemented by the following technical solution: The crop collection device applied to grain drying yards includes a traction frame with connecting ears, a ground contouring unit, and a scraper. The scraper is hinged to the traction frame and connected to the traction frame through the ground contouring unit. The traction frame is connected to a walking device through the connecting ears.

[0005] A further design of the crop collection device applied to a grain drying yard is that the scraper includes: an upper end plate, a lower end plate, a push plate, an auxiliary push plate, and a bushing connected to the upper end plate. The upper end plate is connected to the lower end plate through the push plate to form a main push plate. The auxiliary push plate is fixed to one side of the main push plate. The plane of the main push plate forms an obtuse angle with the traveling direction of the traveling device. A rubber pad is connected to the bottom of the lower end plate.

[0006] A further design of the crop collection device applied to the grain drying yard is that the corresponding sides of the upper and lower end plates are fixed by channel steel.

[0007] A further design feature of the crop collection device applied to the grain drying yard is that reinforcing ribs are welded at intervals on the push panel between the upper and lower end plates.

[0008] A further design of the crop collection device applied to the grain drying yard is that the auxiliary push plate is a bent plate welded together from a long plate and a short plate, with the short plate welded to the main push plate.

[0009] A further design of the crop collection device applied to the grain drying yard is that the long plate has a gap between it and the ground.

[0010] A further design of the crop collection device applied to a grain drying yard is that the traction frame is provided with a connecting piece for each ground contouring unit, and the scraper is provided with a pair of spaced-apart bearings for each ground contouring unit; the ground contouring unit includes: a T-shaped tube and a spring, the horizontal tube of the T-shaped tube is a hollow tube and is set within the interval of the bearings, and the T-shaped tube and the scraper are hinged by a pin passing through the bearing and the horizontal tube, the vertical tube passes through the connecting piece to achieve a movable connection with the traction frame, and the spring is sleeved on the vertical tube above or below the connecting piece.

[0011] A further design of the crop collection device applied to the grain drying yard is that, in the case where the spring is sleeved on the vertical tube on the connecting plate, the top end of the vertical tube is connected to a pin for locking the spring washer.

[0012] A further design of the crop collection device applied to the grain drying yard is that the traction frame is a trapezoidal planar frame, the planar frame is provided with triangular supports and support shafts for connecting scrapers, the planar frame is hinged to the walking mechanism through the triangular suspension formed by the connection points of the connecting ears and the triangular supports, and the planar frame is hinged to the main push plate through the sleeve connection with the support shaft.

[0013] The beneficial effects of this application are as follows: The crop collection device of the present invention, applied to grain drying yards, adopts a pull plate structure with ground contouring function to collect crops in the harvesting and drying yards, greatly improving work efficiency.

Detailed Implementation

[0022] The following will refer to the appendices in the embodiments of the present invention. Figures 1-6 The technical solutions in the embodiments of the present invention will be clearly and completely described. Example 1

[0023] like Figure 1 The crop collection device applied to a grain drying yard in this embodiment mainly consists of a traction frame 1 with connecting ears 13, a ground contouring unit 2, and a scraper 3. The scraper 3 is hinged to the traction frame 1 and connected to the traction frame 1 through the ground contouring unit 2. The traction frame 1 is connected to a walking device (not shown in the figure) through the connecting ears 13. Example 2

[0024] This embodiment is based on embodiment 1, such as... Figure 3 The scraper 3 mainly consists of an upper end plate 301, a lower end plate 302, a pusher plate 303, an auxiliary pusher plate 31, and a bushing 34 connected to the upper end plate 301. The upper end plate 301 is connected to the lower end plate 302 via the pusher plate 303 to form a main pusher plate 30, and the auxiliary pusher plate 31 is fixed to one side of the main pusher plate 30. The plane of the main pusher plate 30 forms an obtuse angle α with the direction of travel of the traveling device, and a rubber pad 33 is connected to the bottom of the lower end plate 302. The main pusher plate 30 is mainly responsible for pushing and collecting crops on the ground. Since its own length direction is not orthogonal to the direction of travel, it also has the function of guiding the crops accumulated due to the collection action along the pusher surface, that is, guiding them to the side of the auxiliary pusher plate, thus achieving the function of directional collection. Through the superposition of the square unit on the ground and the rubber pad 33, the collection efficiency of small-particle crops is improved. On the other hand, this design effectively reduces the direct resistance of crops to the scraper, making it more labor-saving.

[0025] The upper end plate 301 and the lower end plate 302 are fixed on their respective sides by channel steel. Reinforcing ribs 32 are also welded at intervals on the push plate 303 between the upper end plate 301 and the lower end plate 302 to increase the overall strength of the main push plate.

[0026] The auxiliary pusher plate 31 is a bent plate welded from a long plate 312 and a short plate 311, meaning that there is an obtuse angle between the length directions of the long plate 312 and the short plate 311. The short plate 311 is welded to the main pusher plate 30. In this embodiment, a channel steel is also welded to the side of the short plate opposite to the edge channel steel of the main pusher plate. The web plates of the channel steel at the weld between the short plate 311 and the main pusher plate 30 are fixedly connected to each other to form a double-channel steel structure. In this embodiment, the long plate 312 is triangular, and the auxiliary pusher plate 31 has a gap with the ground. The auxiliary pusher plate is mainly responsible for pushing the crops that have been oriented and gathered by the main pusher plate. The auxiliary pusher plate is designed as a bent structure. On the one hand, since the crops on one side of the auxiliary pusher plate have already been gathered, the auxiliary pusher plate no longer needs to guide the gathered crops. Therefore, it is necessary to keep the pushing surface of the auxiliary pusher plate orthogonal to the traveling direction of the walking mechanism as much as possible. On the other hand, the gathered crops have a large resistance to the auxiliary pusher plate. The structural strength is improved by increasing the section modulus through the bent structure. Similarly, the gap between the auxiliary push plate and the ground is also to reduce the resistance of the auxiliary push plate.

[0027] Furthermore, the lower end of the auxiliary pusher plate in this embodiment adopts a sloping design, which can realize the ridge-like stacking of crops.

[0028] like Figure 2 In this embodiment, the traction frame 1 is a trapezoidal planar frame. The planar frame is provided with a triangular support 12 and a support shaft 14 for attaching the scraper. The planar frame is hinged to the traveling mechanism (not shown in the figure) through a triangular suspension formed by the connection point of the connecting lug 13 and the triangular support 12. The planar frame is hinged to the main push plate 30 through the sleeve 34 and the sleeve of the support shaft 14.

[0029] like Figure 4 , Figure 5 In this embodiment, the traction frame 1 is provided with a connecting piece 11 for each ground contouring unit, and the scraper 3 is provided with a pair of spaced-apart bearings 35 for each ground contouring unit 2. The ground contouring unit in this embodiment mainly consists of a T-shaped tube 22 and a spring 23. The horizontal tube of the T-shaped tube 22 is a hollow tube and is positioned within the spacing of the bearings 35. The T-shaped tube and the scraper 3 are hinged by a pin 24 passing through the bearings 35 and the horizontal tube. The vertical tube passes through the connecting piece 11 to achieve a movable connection with the traction frame 1. The spring 23 is sleeved on the vertical tube above or below the connecting piece. For the case where the spring 23 is sleeved on the vertical tube of the connecting piece 11, see [reference needed]. Figure 4 It also includes a spring washer 25 for holding the spring in place, and a pin 26 for engaging the spring washer 25 is inserted through the top of the vertical tube. The two ground contouring units in this embodiment are respectively referred to... Figure 4 , Figure 5 Furthermore, the two ground contouring units are located on both sides of the bushing 34. Example 3

[0030] In this embodiment, the spring in the ground contouring unit is sleeved on the vertical tube of the connecting piece, see [reference]. Figure 4 The spring is fixedly connected to the connecting piece 11 and the crossbar at both ends, and the free length of the spring is the same as the distance between the crossbar and the connecting piece under normal conditions. In this embodiment, there are two ground contouring units, located on both sides of the bushing 34.

[0031] Alternatively, only one ground contouring unit can be set on either side of the bushing 34, or the ground contouring unit can adopt a similar design. Figure 3 The structure shown can achieve the ground contouring effect by applying the above-mentioned limitation method to the spring length and the connection method at both ends. The above-mentioned various settings and combinations are all implemented by those skilled in the art based on Embodiment 3, so they will not be described in detail again.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
