Description

Technical Field

[0001] The present invention relates to the technical field of harvesting machinery, and particularly relates to a straw collecting box device, a straw collecting box assembly, and a harvester. Background Art

[0002] The technology of corn harvesters has gradually matured. Not only do they need to harvest corn ears, but they also need to collect corn straws centrally. The corn straws can be used to feed cattle and sheep, increasing the income. At the same time, due to different sizes of planting areas, terrains of planting areas, and operating habits in different regions, there are different requirements for the sizes of the straw collecting box and the ear box.

[0003] There are mainly three types of existing corn harvester straw collecting box devices or spatial layouts: (1) a top automatic opening and closing straw collecting box device; (2) a structure with a middle ear box and a rear straw collecting box; (3) a structure with the ear box and the straw collecting box placed on both sides of the vehicle body.

[0004] Currently, each of the three mainstream straw collecting box devices or spatial layouts has certain limitations, specifically as follows (note: the following ear unloading and straw unloading frequencies are compared with the top automatic opening and closing straw collecting box device at the same harvesting operation speed):

[0005] (1) Top automatic opening and closing straw collecting box device: Generally located behind the cab, above the peeling machine and the feeder. After the folding straw box is opened, its highest point is much higher than the top of the cab. After being filled with straw, the center moves up, the overall height of the machine in the operating state is high, the passability is poor, and the driving stability is reduced; the applicability is low, and it can only be matched with a corn harvester with a front stalk throwing structure. If a corn harvester with a middle stalk throwing structure uses this structure, the volume of the straw box will be greatly reduced, the straw unloading frequency will be high, and it is not practical; because its own straw unloading rotating shaft is one side of the bottom of the straw collecting box, it is mainly suitable for a grass receiving vehicle with a length of 2.8 m or less. When the straw unloading height is increased to more than 3 m, the cost will increase significantly.

[0006] (2) Structure with a middle ear box and a rear straw collecting box: The layout structure of the middle ear box and the rear straw collecting box compresses the length of the peeling rollers of the corn peeling machine, reducing the peeling effect; the volume of the ear box is relatively small, the ear unloading frequency is high, and the harvesting efficiency is reduced; and due to the restrictions of the peeling machine and the vehicle body, the grain unloading point is low.

[0007] (3) Structure with the ear box and the straw collecting box placed on both sides of the vehicle body: Similar to the layout structure of the middle ear box and the rear straw collecting box, the number of peeling roller groups is restricted by the width of the vehicle body, etc., and to a certain extent, the number of peeling roller groups is compressed and reduced, reducing the peeling effect; the volume of the ear box is less restricted by the lateral vehicle body, the ear unloading frequency is high, and the harvesting efficiency is reduced; the volume of its own straw collecting box is relatively small, the straw unloading frequency is high, and the harvesting efficiency is reduced. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a grass collecting box device, a grass collecting box assembly and a harvester in view of the deficiencies of the prior art.

[0009] The technical solution for the present invention to solve the above technical problems is as follows: A grass collecting box device includes a welded grass box bracket, a grass box unloading drive mechanism and a grass box body. The grass box body is located above the ear box, and the open side at one end is hinged to the welded grass box bracket through an unloading rotating shaft. One end of the grass box unloading drive mechanism is installed on the welded grass box bracket, and its driving end is connected to one side of the grass box body and drives the grass box body to flip and unload grass around the unloading rotating shaft.

[0010] The beneficial effects of the present invention are as follows: After the grass collecting box of the present invention is filled with grass, through the grass box unloading drive mechanism, the grass box body rotates around the unloading rotating shaft on the welded grass box bracket, so that the grass box body rotates and rises, and the forage in the grass collecting box slides out of the box by its own weight for unloading. After unloading, it does not return to its original position temporarily, which can create a flipping space for the ear box below it. When the grass collecting box device of the present invention is in the traveling state (non-unloading state), the highest position is not higher than the top of the cab. In the unloading state, the effective unloading height exceeds 3.2 m, ensuring that the grass collecting box and the ear box have as large a volume as possible within a limited space, improving the utilization rate of the remaining space of the harvester. After adding a large-capacity grass collecting box configuration, it minimizes or does not affect the performance and capacity of the surrounding structure to the greatest extent, reduces the auxiliary operation time, and improves the operation efficiency.

[0011] On the basis of the above technical solutions, the present invention can be further improved as follows.

[0012] Further, the inner side surface of the bottom of the grass box body is a first inclined surface that gradually slopes downward along the forage throwing direction.

[0013] The beneficial effect of adopting the above further solution is: It is convenient for the forage to slide towards one end, avoiding local accumulation of forage in the grass box body.

[0014] Further, the inner side surface of the end of the grass box body hinged to the welded grass box bracket is a second inclined surface, and the second inclined surface is arranged at an acute angle with the open side of the grass box body.

[0015] The beneficial effect of adopting the above further solution is: The setting of the second inclined surface is conducive to the precipitation of forage downward; in addition, when the grass box body flips, the second inclined surface is also conducive to the forage in the grass box body sliding outwards.

[0016] Further, the grass box unloading drive mechanism includes an electric push rod or an oil cylinder or a cylinder; the grass box body adopts a metal plate structure or a mesh structure.

[0017] Further, the straw box body includes a welded straw box body and a welded rotating straw box body that are hinged and communicated with each other. The open side at one end of the welded straw box body is hinged to the welded straw box support through a straw unloading rotating shaft, and the bottom at the other end is hinged to the bottom at one end of the welded rotating straw box body through a rotating shaft of the rotating straw box body.

[0018] The beneficial effect of adopting the above further solution is that by using the hinged welded straw box body and the welded rotating straw box body, the welded rotating straw box body can be flipped and folded with the welded part of the straw box body, creating a flipping space for the ear box below the welded rotating straw box body without affecting the unloading of ears from the ear box.

[0019] Further, the other end of the welded straw box body and one end of the welded rotating straw box body are arranged in a staggered manner, so that after the welded rotating straw box body is flipped relative to the welded straw box body, a part of the welded rotating straw box body overlaps with the welded straw box body.

[0020] The beneficial effect of adopting the above further solution is that the straw box body can be partially folded and made independent without affecting the unloading of ears from the ear box.

[0021] Further, it further includes a driving mechanism for the rotating straw box body. One end of the driving mechanism for the rotating straw box body is installed on the welded straw box body, and its driving end is connected to the welded rotating straw box body and drives the welded rotating straw box body to flip around the rotating shaft of the rotating straw box body.

[0022] Further, the driving mechanism for the rotating straw box body includes an electric push rod, an oil cylinder or a cylinder.

[0023] A straw collecting box assembly includes the straw collecting box device described above and also includes an ear box. The ear box is installed on the lower side of the straw box body and is hinged to the welded straw box support through an ear box rotating shaft, and the ear box rotating shaft is vertically arranged with the straw unloading rotating shaft.

[0024] The beneficial effect of the present invention is that after the straw collecting box of the present invention is filled with straw, through the straw unloading driving mechanism of the straw box, the straw box body rotates around the straw unloading rotating shaft on the welded straw box support, causing the straw box body to rotate and rise. The straw in the straw collecting box slides out of the box by its own weight for straw unloading. After the straw unloading is completed, it does not return to its original position temporarily, creating a flipping space for the ear box below. The ear box below rotates around the ear box rotating shaft and throws ears to one side without being affected by the straw box body. When the straw collecting box device of the present invention is in the traveling state (non-straw unloading state), the highest position is not higher than the top of the cab. In the straw unloading state, the effective straw unloading height exceeds 3.2 m, ensuring that the straw collecting box and the ear box have as large a volume as possible within a limited space, improving the utilization rate of the remaining space of the harvester. After adding a large-capacity straw collecting box configuration, it minimizes or does not affect the performance and capacity of the surrounding structure to the greatest extent, reduces the auxiliary operation time, and improves the operation efficiency.

[0025] A harvester includes the described hay bin device or the described hay bin assembly.

[0026] The beneficial effects of the present invention are as follows: In the harvester of the present invention, through the hay unloading drive mechanism of the hay bin, the hay bin body rotates around the hay unloading rotation shaft welded to the hay bin support, causing the hay bin body to rotate and rise. The forage in the hay bin slides out of the bin by its own weight for hay unloading. After the hay unloading is completed, it does not return to its original position temporarily, which can create a flipping space for the ear box below it. When the hay bin device is in the traveling state (non-hay unloading state), its highest position is not higher than the top of the cab. In the hay unloading state, the effective hay unloading height exceeds 3.2 m, ensuring that the hay bin and the ear box have the largest possible volume within a limited space, can match the harvester (such as a corn harvester that can harvest both ears and stalks), can improve the utilization rate of the remaining space of the harvester, and after adding a large-capacity hay bin configuration, it can minimize or not affect the performance and capacity of the surrounding structures to the greatest extent, reduce the auxiliary operation time, and improve the operation efficiency.

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

[0037] Example 1

[0038] As Figures 1 - 5 shown, a straw collecting box device of this embodiment includes a welded straw collecting box bracket 1, a straw unloading driving mechanism 2 of the straw collecting box, and a straw collecting box body 3. The straw collecting box body 3 is located above the ear box 4, and the open side at one end is hinged to the welded straw collecting box bracket 1 through a straw unloading rotating shaft 5. One end of the straw unloading driving mechanism 2 of the straw collecting box is installed on the welded straw collecting box bracket 1, and its driving end is connected to one side of the straw collecting box body 3 and drives the straw collecting box body 3 to flip and unload straw around the straw unloading rotating shaft 5. The straw unloading driving mechanism 2 of the straw collecting box includes an electric push rod, an oil cylinder or a cylinder.

[0039] Operating condition 1 of the straw collecting box device of this embodiment: As Figure 1 and Figure 2 shown, after the stalks are shredded, by adjusting the stalk throwing cylinder, the shredded stalks are thrown into the straw collecting box body 3. Figure 1 The arrow in Figure 2 is the throwing trajectory of the shredded stalks. After the straw collecting box body 3 is filled with straw, through the straw unloading oil cylinder of the straw collecting box, the straw collecting box body 3 rotates around the straw unloading rotating shaft 5 on the welded straw collecting box bracket 1, so that the straw collecting box body 3 rotates and rises. The state after rising is as shown in

[0040] shown, and the stalks slide out of the straw collecting box body 3 by their own weight for straw unloading. After unloading the stalks, the straw collecting box body 3 is not returned to its original position temporarily, so as to make room for the ear box 4 below it to flip. The ear box 4 can rotate upward around the ear box rotating shaft 41 for operation, so that the ears slide out of the ear box 4. After unloading the ears, the ear box 4 and the straw collecting box body 3 fall back in sequence. The volume ratio of the straw collecting box body 3 to the ear box 4 can be designed and adjusted. It can be adjusted to unload the ears once when unloading the straw twice, or unload the ears once when unloading the straw once, or unload the ears once when unloading the straw three times. The specific adjustment can be selected and designed according to requirements. Figure 1 and Figure 2 shown, when equipped with a straw receiving vehicle, during the harvesting operation, by adjusting the stalk throwing cylinder, the shredded stalks are directly thrown into the straw receiving vehicle. In this operating condition, after the ear box 4 is filled with straw, first raise the straw collecting box body 3 through the straw unloading oil cylinder of the straw collecting box, and then make the ear box 4 rotate upward around the ear box rotating shaft 41 through the ear box oil cylinder to unload the ears. After unloading the ears, the ear box 4 and the straw collecting box body 3 fall back in sequence.

[0041] When the hay collecting box device of this embodiment is in the traveling state (non-hay unloading state), its highest position is not higher than the top of the cab. In the hay unloading state, the effective hay unloading height exceeds 3.2 m. This ensures that within a limited space, the hay collecting box and the ear box have as large a volume as possible, improving the utilization rate of the remaining space of the harvester. After adding a large-capacity hay collecting box configuration, it minimizes or does not affect the performance and capacity of the surrounding structures to the greatest extent, reduces the auxiliary operation time, and improves the operation efficiency.

[0042] Embodiment 2

[0043] As Figures 1 - 5 shown, a hay collecting box device of this embodiment includes a hay box support welding 1, a hay box unloading drive mechanism 2, and a hay box body 3. The hay box body 3 is located above the ear box 4, and the open side at one end is hinged to the hay box support welding 1 through an unloading rotating shaft 5. One end of the hay box unloading drive mechanism 2 is installed on the hay box support welding 1, and its driving end is connected to one side of the hay box body 3 and drives the hay box body 3 to flip and unload hay around the unloading rotating shaft 5.

[0044] As Figures 1 - 5 shown, the inner side of the bottom of the hay box body 3 of this embodiment is a first inclined surface 31 that gradually slopes downward along the throwing direction of the forage. The first inclined surface 31 can be on one plane or not on one plane. For example, the inner side of the bottom of the hay box body 3 first slopes downward at a first angle and then slopes downward at a second angle, and the second angle is greater than the first angle. Reference can be made to Figure 1 and Figure 2 . The setting of the first inclined surface 31 facilitates the sliding of the forage to one end and avoids local accumulation of forage in the hay box body.

[0045] As Figures 1 - 5 shown, the inner side of the end where the hay box body 3 is hinged to the hay box support welding 1 is a second inclined surface 32, and the second inclined surface 32 is arranged at an acute angle with the open side of the hay box body 3. When the hay box body is flipped, the second inclined surface is also conducive to the outward sliding of the forage in the hay box body. The first inclined surface and the second inclined surface form a structure similar to a constricted opening, which is conducive to the concentrated downward collection of forage.

[0046] The hay box unloading drive mechanism 2 of this embodiment includes an electric push rod, an oil cylinder, or a cylinder; the hay box body 3 adopts a metal plate-like structure or a mesh structure.

[0047] The first operating condition of the hay collecting box device of this embodiment: As Figure 1 and Figure 2 shown, after the stalks are chopped, by adjusting the stalk throwing cylinder, the chopped stalks are thrown into the hay box body 3. Figure 1The arrow in [it] is the throwing trajectory of the chopped stalks. After the grass box body 3 is filled with grass, the grass box body 3 is rotated around the unloading rotating shaft 5 on the grass box bracket welding 1 by the grass box unloading oil cylinder, so that the grass box body 3 is rotated and raised. The raised state is as shown in Figure 2 shown. The stalks slide out of the grass box body 3 along the second inclined plane 32 by their own weight for unloading grass. After unloading the stalks, the grass box body 3 is not returned to its original position temporarily, so as to make room for the ear box 4 below it to turn over. The ear box 4 can be rotated and raised upward around the ear box rotating shaft 41 for operation, so that the ears slide out of the ear box 4. After unloading the ears, the ear box 4 and the grass box body 3 fall back in turn. The volume ratio of the grass box body 3 to the ear box 4 can be adjusted by design. It can be adjusted to unload the ears once when unloading the stalks twice, or unload the ears once when unloading the stalks once, or unload the ears once when unloading the stalks three times. The specific adjustment can be selected and designed according to the requirements.

[0048] Working condition two of the grass collection box device in this embodiment: As shown in Figure 1 and Figure 2 shown, when equipped with a grass receiving vehicle, during the harvesting operation, by adjusting the stalk throwing cylinder, the chopped stalks are directly thrown into the grass receiving vehicle. In this working condition, after the ear box 4 is filled with grass, first raise the grass box body 3 through the grass box unloading oil cylinder, and then make the ear box 4 rotate and raise upward around the ear box rotating shaft 41 through the ear box oil cylinder for unloading the ears. After unloading the ears, the ear box 4 and the grass box body 3 fall back in turn.

[0049] In the traveling state (non-unloading state) of the grass collection box device in this embodiment, the highest position is not higher than the top of the cab. The effective unloading height in the unloading state exceeds 3.2 m, ensuring that the grass collection box and the ear box have as large a volume as possible within a limited space, which can improve the utilization rate of the remaining space of the harvester. After adding a large-capacity grass collection box configuration, the performance and capacity of the surrounding structures are minimized or not affected, the auxiliary operation time is reduced, and the operation efficiency is improved.

[0050] Embodiment 3

[0051] As shown in Figures 1 - 5 shown, a grass collection box device in this embodiment includes a grass box bracket welding 1, a grass box unloading drive mechanism 2 and a grass box body 3. The grass box body 3 is located above the ear box 4, and the open side at one end is hinged to the grass box bracket welding 1 through an unloading rotating shaft 5. One end of the grass box unloading drive mechanism 2 is installed on the grass box bracket welding 1, and its driving end is connected to one side of the grass box body 3 and drives the grass box body 3 to turn over and unload grass around the unloading rotating shaft 5.

[0052] As shown in Figure 3 and Figure 4As shown in the figure, the grass box body 3 of this embodiment includes a welded grass box body 33 and a welded grass box rotating body 34 that are hinged and communicated with each other. One open side of the welded grass box body 33 is hinged to the welded grass box support 1 through a grass unloading rotating shaft 5, and the bottom of the other end is hinged to the bottom of one end of the welded grass box rotating body 34 through a grass box rotating body rotating shaft 35. By using the hinged welded grass box body and the welded grass box rotating body, the welded grass box rotating body can be flipped and folded with a part of the welded grass box body, creating a flipping space for the ear box below the welded grass box rotating body without affecting the ear unloading of the ear box.

[0053] As Figure 5 shown in the figure, one end of the welded grass box body 33 of this embodiment is arranged offset from one end of the welded grass box rotating body 34. After the welded grass box rotating body 34 is flipped relative to the welded grass box body 33, a part of the welded grass box rotating body 34 overlaps with the welded grass box body 33, and it is independent and does not affect other structures. Refer to Figures 3 - 5 , the left and right dimensions of the welded grass box rotating body 34 are designed to be smaller than the left and right dimensions of the welded grass box body 33, and the welded grass box rotating body 34 can be flipped and partially folded into the welded grass box body 33 after flipping. Of course, the welded grass box rotating body 34 and the welded grass box body 33 can be closely attached to prevent forage from leaking through the gaps. It is also possible to design the left and right dimensions of the welded grass box rotating body 34 to be larger than the left and right dimensions of the welded grass box body 33, and the welded grass box rotating body 34 can be flipped and partially folded to cover the welded grass box body 33 after flipping.

[0054] As Figure 4 and Figure 5 shown in the figure, the grass box device of this embodiment further includes a grass box rotating body driving mechanism 6. One end of the grass box rotating body driving mechanism 6 is installed on the welded grass box body 33, and its driving end is connected to the welded grass box rotating body 34 and drives the welded grass box rotating body 34 to flip around the grass box rotating body rotating shaft 35. The grass box rotating body driving mechanism 6 of this embodiment includes an electric push rod or an oil cylinder or a cylinder.

[0055] Working condition 1 of the grass box device of this embodiment: As Figure 1 and Figure 2 shown in the figure, after the stalks are chopped, the chopped stalks are thrown into the grass box body 3 by adjusting the stalk throwing cylinder. Figure 1 The arrow in Figure 2As shown in the figure, the stalks slide out of the straw box body 3 by their own weight for unloading straw. After unloading the stalks, the straw box body 3 is not returned to its original position temporarily, so as to create a turning space for the ear box 4 below it. The ear box 4 can rotate upward around the ear box rotation shaft 41 for operation, so that the ears slide out of the ear box 4. After unloading the ears, the ear box 4 and the straw box body 3 fall back in turn. The volume ratio of the straw box body 3 to the ear box 4 can be adjusted by design. It can be adjusted to unload the ears once when unloading the straw twice, or unload the ears once when unloading the straw once, or unload the ears once when unloading the straw three times. The specific adjustment can be selected and designed according to requirements.

[0056] Operating condition 2 of the straw collecting box device in this embodiment: As Figure 3 and Figure 4 shown, when a straw receiving vehicle is equipped, during the harvesting operation, by adjusting the stalk throwing cylinder, the chopped stalks are directly thrown into the straw receiving vehicle. In this operating condition, by contracting the straw box rotating cylinder, the straw box rotating welded part 34 rotates upward around the straw box rotating shaft 35 to the state as shown in Figure 3 and Figure 4 . In this state, the process of unloading ears of the straw box body 3 does not affect the ear box 4. The ear box 4 can directly rotate upward around the ear box rotation shaft 41 for operation, so that the ears slide out of the ear box 4. After unloading the ears, the ear box 4 falls back. In this operating condition, the straw box body can always be in a semi-folded state without falling back. That is to say, it is not necessary to operate the straw box every time when unloading grain. After a harvesting operation is completed, the straw box can be fallen back, avoiding wasting operation time. When the straw box is fallen back after a harvesting operation is completed, use the straw box rotating cylinder to drive the straw box rotating welded part 34 to rotate downward around the straw box rotating shaft 35 to the state as shown in Figure 1 .

[0057] In the traveling state (non-unloading state) of the straw collecting box device in this embodiment, the highest position is not higher than the top of the cab. The effective unloading height in the unloading state exceeds 3.2 m, ensuring that the straw collecting box and the ear box have as large a volume as possible within a limited space, improving the utilization rate of the remaining space of the harvester. After adding a large-capacity straw collecting box configuration, the performance and capacity of the surrounding structures are minimized or not affected, reducing the auxiliary operation time and improving the operation efficiency.

[0058] Embodiment 4

[0059] As Figures 1 - 5 shown, a straw collecting box device in this embodiment includes a straw box support welded part 1, a straw box unloading drive mechanism 2 and a straw box body 3. The straw box body 3 is located above the ear box 4, and the open side at one end is hinged to the straw box support welded part 1 through an unloading rotation shaft 5. One end of the straw box unloading drive mechanism 2 is installed on the straw box support welded part 1, and its driving end is connected to one side of the straw box body 3 and drives the straw box body 3 to flip and unload straw around the unloading rotation shaft 5.

[0060] As Figures 1 - 5 shown, the inner side of the bottom of the hay box body 3 in this embodiment is a first inclined surface 31 that gradually slopes downward along the throwing direction of the hay. The first inclined surface 31 can be on a single plane or not on a single plane. For example, the inner side of the bottom of the hay box body 3 first slopes downward at a first angle and then slopes downward at a second angle, where the second angle is greater than the first angle. Reference can be made to Figure 1 and Figure 2 . The setting of the first inclined surface 31 facilitates the sliding of the hay towards one end, avoiding local accumulation of hay inside the hay box body.

[0061] As Figures 1 - 5 shown, the inner side of one end of the hay box body 3 hinged to the hay box support welded part 1 is a second inclined surface 32, and the second inclined surface 32 is arranged at an acute angle with the open side of the hay box body 3. When the hay box body is flipped, the second inclined surface also facilitates the sliding of the hay inside the hay box body outwards. The first inclined surface and the second inclined surface form a structure similar to a converging opening, which is conducive to the concentrated downward collection of the hay.

[0062] The hay unloading driving mechanism 2 in this embodiment includes an electric push rod, an oil cylinder or a cylinder; the hay box body 3 adopts a metal plate structure or a mesh structure.

[0063] As Figure 3 and Figure 4 shown, the hay box body 3 in this embodiment includes a hay box body welded part 33 and a hay box rotating body welded part 34 that are hinged to each other and communicate. One open side of the hay box body welded part 33 is hinged to the hay box support welded part 1 through a hay unloading rotating shaft 5, and the bottom of the other end is hinged to the bottom of one end of the hay box rotating body welded part 34 through a hay box rotating body rotating shaft 35. By using the hinged hay box body welded part and hay box rotating body welded part, the hay box rotating body welded part can be flipped and folded with the hay box body welded part, creating a flipping space for the ear box below the hay box rotating body welded part without affecting the unloading of ears from the ear box.

[0064] As Figure 5 shown, the other end of the hay box body welded part 33 and one end of the hay box rotating body welded part 34 are arranged in a staggered manner, so that after the hay box rotating body welded part 34 is flipped relative to the hay box body welded part 33, a part of the hay box rotating body welded part 34 overlaps with the hay box body welded part 33, without occupying too much body space. Reference can be made to Figures 3 - 5, the left and right dimensions of the hay bin swivel welding 34 are designed to be smaller than those of the hay bin body welding 33, so that the hay bin swivel welding 34 can be partially folded into the hay bin body welding 33 after being flipped. Of course, the hay bin swivel welding 34 and the hay bin body welding 33 can be closely fitted to prevent forage from leaking through the gaps. It is also possible to design the left and right dimensions of the hay bin swivel welding 34 to be larger than those of the hay bin body welding 33, so that the hay bin swivel welding 34 can be partially folded and wrapped around the hay bin body welding 33 after being flipped.

[0065] As Figure 4 and Figure 5 shown, the hay bin assembly of this embodiment further includes a hay bin swivel drive mechanism 6. One end of the hay bin swivel drive mechanism 6 is installed on the hay bin body welding 33, and its drive end is connected to the hay bin swivel welding 34 and drives the hay bin swivel welding 34 to flip around the hay bin swivel axis 35. The hay bin swivel drive mechanism 6 of this embodiment includes an electric push rod, an oil cylinder or a cylinder.

[0066] Working condition 1 of the hay bin assembly of this embodiment: As Figure 1 and Figure 2 shown, after the stalks are chopped, the chopped stalks are thrown into the hay bin body 3 by adjusting the stalk throwing cylinder. Figure 1 The arrow in Figure 2 is the throwing trajectory of the chopped stalks. After the hay bin body 3 is filled with hay, the hay bin body 3 is rotated around the unloading rotation axis 5 on the hay bin support welding 1 by the hay bin unloading oil cylinder, so that the hay bin body 3 rotates and rises. The state after rising is as

[0067] shown. The stalks slide out of the hay bin body 3 along the second inclined plane 32 by their own weight for unloading hay. After unloading the stalks, the hay bin body 3 is not returned to its original position temporarily, so as to make room for the ear box 4 below it to flip. The ear box 4 can rotate and rise upward around the ear box rotation axis 41 for operation, so that the ears slide out of the ear box 4. After unloading the ears, the ear box 4 and the hay bin body 3 fall back in sequence. By designing and adjusting the volume ratio of the hay bin body 3 and the ear box 4, it can be adjusted to unload the ears once when unloading the stalks twice, or unload the ears once when unloading the stalks once, or unload the ears once when unloading the stalks three times. The specific adjustment can be selected and designed according to requirements.

[0067] Working condition 2 of the hay bin assembly of this embodiment: As Figure 3 and Figure 4 shown, when a hay receiving vehicle is equipped, during the harvesting operation, by adjusting the stalk throwing cylinder, the chopped stalks are directly thrown into the hay receiving vehicle. In this working condition, by contracting the hay bin swivel oil cylinder, the hay bin swivel welding 34 rotates upward around the hay bin swivel axis 35 to the state as Figure 3 and Figure 4In this state, the unloading process of the ear box 4 is not affected by the grass box body 3. The grass box body 3 can be directly rotated upward around the ear box rotation axis 41 of the ear box 4 for operation, so that the ears slide out of the ear box 4. After unloading the ears, it then falls back to the ear box 4. In this working condition, the grass box body can always remain in the semi-folded state without falling back. That is to say, it is not necessary to operate the grass box every time when unloading grain. After a harvesting operation is completed, the grass box can be fallen back, thus avoiding wasting operation time. When the grass box is fallen back after a harvesting operation is completed, the grass box body rotation oil cylinder is used to drive the grass box body welding 34 to rotate downward around the grass box body rotation axis 35 to the state as shown in Figure 1 is sufficient.

[0068] In the traveling state (non-grass unloading state) of the grass collection box device of this embodiment, the highest position is not higher than the top of the cab. The effective grass unloading height in the grass unloading state exceeds 3.2 m, ensuring that the grass collection box and the ear box have as large a volume as possible within a limited space, which can improve the utilization rate of the remaining space of the harvester. After adding a large-capacity grass collection box configuration, it minimizes or does not affect the performance and capacity of the surrounding structures to the greatest extent, reduces the auxiliary operation time, and improves the operation efficiency.

[0070] As Figures 1 - 5 shown, a grass collection box assembly of this embodiment includes the grass collection box device described in any one of Embodiments 1-4, and further includes an ear box 4. The ear box 4 is installed on the lower side of the grass box body 3 and is hinged to the grass box bracket welding 1 through the ear box rotation axis 41. The ear box rotation axis 41 is perpendicularly arranged with the grass unloading rotation axis 5. In this embodiment, the grass box body 3 can be thrown backward, and the ear box 4 can be thrown to the left or right.

[0071] After the grass collection box of this embodiment is filled with grass, through the grass box unloading drive mechanism, the grass box body rotates around the grass unloading rotation axis on the grass box bracket welding, so that the grass box body rotates and rises. The forage in the grass collection box slides out of the box by its own weight for grass unloading. After the grass unloading is completed, it does not return to its original position temporarily, which can create a flipping space for the ear box below. The ear box below throws the ears to one side around the ear box rotation axis, without being affected by the grass box body. In the traveling state (non-grass unloading state) of the grass collection box device of this embodiment, the highest position is not higher than the top of the cab. The effective grass unloading height in the grass unloading state exceeds 3.2 m, ensuring that the grass collection box and the ear box have as large a volume as possible within a limited space, which can improve the utilization rate of the remaining space of the harvester. After adding a large-capacity grass collection box configuration, it minimizes or does not affect the performance and capacity of the surrounding structures to the greatest extent, reduces the auxiliary operation time, and improves the operation efficiency.
