[0033] According to a first aspect of the present utility model, a low-loss conveying housing is provided, such as Figures 1 to 5As shown, the low-loss conveying housing is used for the auger cleaning device, which can prevent the grains from being discharged with the auger and reduce the waste of grain. The auger cleaning device may include a main body bracket 1 and an auger body 2. The auger body 2 is rotatably arranged on the main body bracket 1. The main body bracket 1 can be formed into a frame structure for the installation of the auger body 2 and the low-loss conveying housing. The auger body 2 can be a spiral shaft, and the rotation of its spiral blades is used to push materials such as bracts forward. However, it is not limited to this. The blades of the auger body 2 can also be formed in a combination of spiral blades and spike teeth, and the structure of the auger body 2 can be specifically selected according to needs. When the spiral shaft rotates, the part of the blade edge in contact with the conveying trough pushes the material to move along the conveying direction. The low-loss conveying housing includes a screen main body 3 and a plurality of blocking members 4.

[0034] In the following description, reference will be made to Figures 1 to 5 Specifically describe the detailed structures of the screen main body 3 and the plurality of blocking members 4 of the low-loss conveying housing. In addition, in the description of the embodiments, two directions are also involved, namely the first direction S1 and the second direction S2. The first direction S1 can be understood as the direction from one end to the other end in the length direction of the low-loss conveying housing, and the second direction S2 can be understood as the direction from one end to the other end in the width direction of the low-loss conveying housing.

[0035] As Figures 1 to 5 shown, in the embodiment, the low-loss conveying housing includes a screen main body 3 and a blocking member 4. The screen main body 3 is disposed around the lower part of the auger body 2. The screen main body 3 is provided with a plurality of screen holes 301 for the grains to pass through. The number of blocking members 4 is multiple, and the multiple blocking members 4 are arranged at intervals along the movement direction of the auger body 2 on the screen main body 3. The screen main body 3 can be a filtering member with a plurality of screen holes 301 for the grains to pass through. When the auger body 2 moves, the grains fall from the bracts and fall into the collector (not shown) through the screen main body 3 at the lower part of the auger body 2 to achieve the collection of the grains. The blocking member 4 is arranged at the lower part of the auger body 2, and the multiple blocking members 4 are arranged at intervals along the movement direction of the auger body 2. Since during the movement of the auger body 2, some grains are discharged together with the bracts due to the influence of inertia force, arranging a plurality of blocking members 4 in the movement direction of the auger body 2 can block the grains from being discharged together with the bracts, prevent the grains from being pushed by the auger body 2 to the outside of the machine under the action of inertia, thereby improving the cleaning effect and reducing the grain loss.

[0036] The blocking member 4 can be formed as a circular steel piece made of steel, and the circular steel piece is used to cooperate with the screen main body 3 formed as an arc-shaped member described below. However, it is not limited to this, and the shape of the blocking member 4 can be specifically selected according to the shape of the screen main body 3.

[0037] The low-loss conveying housing is provided with a blocking member 4 on the screen body 3, which can prevent the grains from being discharged together with the bracts under the influence of inertia force, thereby improving the cleaning effect, reducing grain loss, and avoiding waste of food.

[0038] Preferably, as Figures 1 to 4 shown, in the embodiment, the screen body 3 can be formed as an arc-shaped member, and the number of arc-shaped members can be multiple. The multiple arc-shaped members are connected to each other. The number of the auger body 2 is set in one-to-one correspondence with the number of the screen body 3. Each arc-shaped member is disposed around the lower part of the auger body 2. In the auger cleaning device, there may be multiple auger bodies 2, and the number of the screen body 3 needs to be set in one-to-one correspondence with the auger body 2.

[0039] Preferably, as Figure 4 shown, in the embodiment, the low-loss conveying housing may further include a shielding member 7. Both ends of the shielding member 7 are connected to the screen body 3, and the shielding member 7 is disposed around the upper part of the auger body 2. The shielding member 7 can shield the upper part of the auger body 2 to prevent the material from flying out or coming off. The shielding member 7 can be formed as an arc-shaped member and is connected to the screen body 3 by welding or using fastening bolts.

[0040] Preferably, as Figures 1 to 4 shown, in the embodiment, the length of the screen body 3 corresponds to the length of the auger body 2, so that the screen body 3 can completely cover the auger body 2.

[0041] Furthermore, the low-loss conveying housing has three embodiments, which differ in the setting position of the blocking member 4. The following describes these three embodiments respectively.

[0042] Preferably, as Figure 1 shown, in the first embodiment, the screen body 3 can be formed as an arc-shaped member, and the arc-shaped member can cooperate with the auger body 2 formed as a spiral shaft and cover the lower part of the auger body 2 to ensure the collection of grains. The blocking member 4 is disposed on the arc-shaped member along the circumferential direction of the arc-shaped member. The low-loss conveying housing may include two screen bodies 3 connected to each other, so as to be adapted to the auger cleaning device having two auger bodies 2. The multiple blocking members 4 disposed along the circumferential direction can play a role in blocking the grains, thereby preventing the grains from being discharged following the movement of the auger body 2.

[0043] Preferably, as Figure 1As shown, in the first embodiment, first fixing members 5 are provided at both ends of the screen body 3 in the first direction S1, and the screen body 3 is arranged on the main body bracket 1 through the first fixing members 5. Both ends of the two arc-shaped screen bodies 3 can be installed on the main body bracket 1 through the first fixing members 5. The first fixing member 5 can be formed as a mounting plate having mounting holes, and the mounting plate can be fixedly installed on the main body bracket 1 by using fastening bolts and the mounting holes.

[0044] Preferably, as Figure 1 shown, in the first embodiment, second fixing members 6 are provided at both ends of the screen body 3 in the second direction S2, and the screen body 3 formed as an arc-shaped member can be arranged on the main body bracket 1 through the second fixing members 6. Since the low-loss conveying housing has two screen bodies 3, two adjacent sides of the two screen bodies 3 can also be connected through the second fixing members 6. The second fixing member 6 can be formed as a strip-shaped plate structure, and the strip-shaped plate structure is also provided with a plurality of mounting holes, and the strip-shaped plate structure can be fixedly installed on the main body bracket 1 by using fastening bolts and the mounting holes.

[0045] Preferably, as Figure 2 and Figure 3 shown, in the second embodiment, since the screen body 3 can be formed as an arc-shaped member, a middle axis L1 can be provided at the center of the arc-shaped member, and the middle axis L1 can be the extension line where the center of the arc is located. As Figure 2 and Figure 3 shown, the cleaning device can include two auger bodies 2 adjacent to each other. Each auger body 2 is provided with a corresponding screen body 3, and each screen body 3 is provided with a plurality of blocking members 4.

[0046] Preferably, in the second embodiment, an included angle is provided between the blocking member 4 and the middle axis L1 in the projection direction. That is, it can be understood that in the first embodiment, the blocking member 4 is arranged perpendicular to the middle axis L1, and in the second embodiment, the blocking member 4 is arranged obliquely to the middle axis L1. The obliquely arranged blocking member 4 can also play a role in guiding the flow.

[0047] Preferably, as Figure 2 shown, in the second embodiment, left and right (here, left and right refer to Figure 2The blocking members 4 of the two adjacent screen bodies 3 (left and right) in [description] are arranged differently. The blocking member 4 of the screen body 3 on the left is arranged obliquely, and the blocking member 4 of the screen body 3 on the right is perpendicular to the central axis L1. This can match the auger body 2 with different structures. For example, the obliquely arranged blocking member 4 can match the auger body 2 with a combination of spiral blades and spike teeth. The blocking member 4 can play a role in guiding the flow while blocking the grains; the vertically arranged blocking member 4 can match the auger body 2 with all spiral blades.

[0048] Preferably, as Figures 2 to 4 shown, in the second embodiment, first fixing members 5 are provided at both ends of the screen body 3 in the first direction S1, and second fixing members 6 are provided at both ends of the screen body 3 in the second direction S2. In the second embodiment, the shapes, structures, and installation methods of the first fixing members 5 and the second fixing members 6 are the same as those in the first embodiment described above, and will not be elaborated here.

[0049] However, not limited to the above two embodiments, referring to Figure 4 , in the third embodiment, the number of screen bodies 3 can also be more, for example, four. The four screen bodies 3 can match four auger bodies 2. The blocking members 4 of the four screen bodies 3 can be arranged obliquely or perpendicular to the central axis L1. Those skilled in the art can select according to the specific structure of the cleaning device. As Figure 1 shown, the blocking members 4 can be arranged in sequence at any angle with respect to the first direction S1, can be arranged obliquely or perpendicular to the first direction S1, and can also be arranged crosswise with each other.

[0050] By sequentially and spacedly arranging a plurality of blocking members on the screen body, the low-loss conveying housing can prevent the grains from being discharged along with the movement of the auger body due to the influence of inertia force, avoid waste of grain, and thus improve the cleaning effect.

[0051] In addition, as Figure 5 shown, according to the second aspect of the present invention, an auger cleaning device is provided. The auger cleaning device includes the low-loss conveying housing as described above. During the use of the auger cleaning device, through the low-loss conveying housing, it is possible to prevent the grains from being discharged along with the movement of the auger body 2, avoid waste of grain, and improve the cleaning effect.
