Description

Technical Field

[0001] The utility model relates to the technical field of grain harvesters, in particular to a grain recovery box with a maintenance space. Background Art

[0002] The grain recovery box of the harvester is used to collect grains of crops such as corn. Generally, the grain harvester used to harvest corn is equipped with equipment such as a husk peeler, a separator, and a press feeder. When the husk peels the corn, the husks carry grains. The grains are separated and recovered by the separation mechanism and then sent to the grain recovery box by the press feeder. When the grain recovery box is full, the harvester needs to stop working and continue the harvesting operation after unloading the grains onto the transport vehicle.

[0003] In order to reduce the frequency of grain unloading and ensure that the harvester can operate for a long time at a time, the volume of the grain recovery box should be as large as possible. At the same time, nearby equipment such as the pressure feeder needs to be adjusted and repaired according to the operating conditions, and sufficient operating space is required for the adjustment and maintenance equipment. As a result, there is a technical contradiction between the volume of the grain recovery box and the maintenance space of the equipment. If the volume of the grain recovery box is to be increased, the space it occupies will inevitably increase, thereby reducing the maintenance space of the equipment, resulting in troubles in equipment adjustment and maintenance, increasing maintenance time, and virtually reducing the effective time of the user's operation, affecting the harvesting efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to increase the volume of the grain recovery box and ensure the maintenance and operation space of other equipment at the same time.

[0007] The beneficial effects of the utility model are:

[0008] By adopting the utility model, the first guide structure and the second guide structure are used to ensure that the position of the pull-out plate is stable, thereby avoiding leakage of grains; the gap is closed by the pull-out plate to increase the volume of the grain recovery box, thereby ensuring that the harvester can operate for a longer time at a time; the gap is exposed by sliding the pull-out plate, thereby converting the internal space of the grain box into a maintenance operation space, which is convenient for equipment adjustment and maintenance; thereby increasing the effective operation time of the user and improving the harvesting efficiency.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the first guide structure includes two strip plates arranged opposite to each other, the two strip plates are arranged vertically, there is a gap between the two strip plates, and one edge of the pull-out plate is inserted into the gap between the two strip plates and can slide up and down.

[0016] Furthermore, a third bent portion is provided on the upper portion of the pull-out plate. When the pull-out plate is inserted into the gap between the two strip plates and closes the gap, the third bent portion at least partially overlaps with the second bent portion of one of the strip plates.

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] This utility model refers to Figure 1-6 .

[0038] The utility model provides a grain recovery box with a maintenance space, comprising a grain box 1 with a top opening, a notch and a pull-out plate 2 being provided on at least one side wall of the grain box 1, and the pull-out plate 2 being capable of closing the notch; a first guide structure being provided on one side of the notch, and a second guide structure being provided on the other side of the notch, the first guide structure and the second guide structure being arranged opposite to each other and both being arranged vertically, an edge of the pull-out plate 2 being slidably connected to the first guide structure, and the other edge of the pull-out plate 2 being slidably connected to the second guide structure, and the notch being able to be exposed when the pull-out plate 2 slides vertically.

[0039] principle:

[0040] The grain box 1 is the original grain recovery box, which is installed on the harvester and is used to collect grains of crops such as corn. Figure 6 As shown, the gap of the seed box 1 faces the equipment that needs to be adjusted or repaired, such as the existing pressure feeder assembly 10 and other equipment. When harvesting, the pull-out plate 2 closes the gap, so that the height of the gap can be used to accommodate grains, increasing the volume of the grain recovery box. When adjusting and repairing the pressure feeder assembly 10 and other equipment, the pull-out plate 2 is slid to expose the gap, and the space of the seed box 1 at the gap can be used as a repair operation space, which is convenient for equipment adjustment and repair, and avoids additional repair and maintenance time.

[0041] Note: The first guide structure and the second guide structure may have the same structure or different structures.

[0042] By adopting the utility model, the first guide structure and the second guide structure are used to ensure that the position of the pull-out plate 2 is stable, thereby avoiding leakage of grains; the gap is closed by the pull-out plate 2 to increase the volume of the grain recovery box, thereby ensuring that the harvester can operate for a longer time at a time; the gap is exposed by sliding the pull-out plate 2, thereby converting the internal space of the grain box 1 into a maintenance operation space, which is convenient for equipment adjustment and maintenance; thereby increasing the effective operation time of the user and improving the harvesting efficiency.

[0043] Further, such as Figure 3-5 As shown: the first guide structure includes two strip plates 3 arranged opposite to each other, the two strip plates 3 are arranged vertically, there is a gap between the two strip plates 3, one edge of the pull-out plate 2 is inserted into the gap between the two strip plates 3 and can slide up and down.

[0044] The two strip plates 3 overlap with an edge portion of the pull-out plate 2, which is convenient for preventing the pull-out plate 2 from deforming and providing good sliding stability for the pull-out plate 2; at the same time, the sealing performance between the pull-out plate 2 and the side wall of the grain box 1 is improved to prevent grain leakage.

[0045] Furthermore, the strip plate 3 is provided with a first bending portion 4 , which together with the strip plate 3 forms an angle steel shape. The first bending portions 4 of the two strip plates 3 extend in opposite directions, and the first bending portions 4 are attached to and fixed on the side wall of the grain box 1 .

[0046] When the pull-out plate 2 extends into the gap between the two strip plates 3, it can directly contact the side wall of the grain box 1, reducing the gap between the edge of the pull-out plate 2 and the side wall of the grain box 1, thereby avoiding waste caused by leakage of grains.

[0047] Furthermore, the two ends of the strip plate 3 are provided with a second bending portion 5 , the second bending portion 5 forms an obtuse angle with the strip plate 3 where the second bending portion 5 is located, and the second bending portions 5 of the two strip plates 3 extend in opposite directions.

[0048] By extending the second bending portions 5 of the two strip plates 3 in opposite directions, the gap between the two strip plates 3 becomes gradually wider at both ends, making it easy to insert the pull-out plate 2 and install it conveniently; at the same time, it can support the limiting structure on the pull-out plate 2 to prevent the pull-out plate 2 from being stuck in the gap.

[0049] Furthermore, a third bending portion 6 is provided on the upper portion of the pull-out plate 2 . When the pull-out plate 2 is inserted into the gap between the two strip plates 3 and closes the gap, the third bending portion 6 at least partially overlaps with the second bending portion 5 of one of the strip plates 3 .

[0050] Preferably, the third bent portion 6 extends toward the outside of the pull-out plate 2 .

[0051] It is convenient to support the pull-out plate 2, avoid the third bent portion 6 of the pull-out plate 2 from being greatly deformed and stuck in the gap, and is easy to disassemble and assemble.

[0052] Furthermore, a wing plate is provided on the side wall of the grain box 1 below the notch. The wing plate is inclined from bottom to top toward the outer side of the grain box 1 , and the inner side of the wing plate is flush with the inner side wall of the grain box 1 .

[0056] When the pull-out plate 2 is installed, the edge of the pull-out plate 2 partially overlaps with the side wall plate 7. When the pull-out plate 2 is subjected to the pressure of the grains, the pull-out plate 2 can be tightly attached to the side wall plate 7 to prevent a gap from being generated between the edge of the pull-out plate 2 and the grain recovery box, thereby avoiding grain leakage.

[0057] Furthermore, a fourth bending portion 9 is provided on the upper portion of the side wall plate 7, and a third bending portion 6 is provided on the upper portion of the pull-out plate 2, and the third bending portion 6 and the fourth bending portion 9 both extend toward the outer side of the pull-out plate 2; when the pull-out plate 2 is inserted into the gap between the slide bar 8 and the side wall plate 7 and the gap is closed, the third bending portion 6 is located above the fourth bending portion 9.

[0058] It is convenient to limit the pull-out plate 2 to prevent the pull-out plate 2 from being stuck in the gap between the slide bar 8 and the side wall plate 7; at the same time, the fourth bent portion 9 provides support for the third bent portion 6, increasing the contact surface and preventing the pull-out plate 2 from being greatly deformed by impact.

[0059] Furthermore, when the pull-out plate 2 is inserted into the gap between the slide bar 8 and the side wall plate 7 and closes the gap, the edge of the third bent portion 6 overlaps with the edge of the fourth bent portion 9 .

[0060] The edge of the third bending portion 6 overlaps with the edge of the fourth bending portion 9, thereby avoiding the generation of gaps that may cause seed leakage.

[0061] Furthermore, the notch is located at the upper part of the grain box 1 .
