[0035] As Figures 1 to 6 shown, the present utility model discloses a transmission mechanism capable of continuous operation with two bins, including a front bin c1, a rear bin c2, a lower bin c3 and a transmission structure c4. Figure 1 is a schematic diagram of a transmission mechanism capable of continuous operation with two bins in the embodiment of the present utility model in a state where the front bin is opened. Specifically, as Figure 1As shown in the figure, the front bin c1 is used for the caching and pre - processing of forage; the rear bin c2 is connected in parallel with the front bin c1 and is used for the forming, net - winding and bale - unloading operations of forage; the lower bin c3 is arranged at the bottom of the front bin c1 and the rear bin c2 and is used to control the feeding direction of forage and assist in the transfer of bales; the transmission structure c4 is connected to the front bin c1 and the lower bin c3. The transmission structure c4 is configured to drive the lower bin c3 to rise when the bale in the rear bin c2 is completely formed and undergoes net - winding operation, so that the forage is pre - formed in the front bin c1. After the forage net - winding and bale - unloading are completed, the transmission structure c4 drives the lower bin c3 to return to its original position and controls the opening of the front bin c1, so that the forage enters the rear bin c2 for forming. As Figure 1 As shown in the figure, in the embodiment of the utility model, the structure of the rear bin c2 is the same as that of the rear bin of the original model, and it opens backward when specifically opened; of course, in the embodiment of the present utility model, the feeding performance of the rear bin flat roller can also be increased, which can not only prevent the accumulation of forage in the lower bin, but also increase the density of the formed bales in the rear bin. The lower bin c3 completes the conveying and stopping of forage through lifting. When the front bin c1 is opened, it opens towards the rear bin c2. Through this structural form, the pre - formed bales in the front bin c1 can be pushed into the rear bin c2 together. The net - winding and net - cutting operations in the rear bin c2 are conventional techniques in this field and will not be elaborated here.

[0036] In the above - mentioned embodiment, through the setting of the transmission structure c4, the forage is first pre - formed in the front bin c1, and then transferred to the rear bin c2 to complete the forming. At this time, the lower bin c3 rises, so that the forage continues to be pre - formed in the front bin c1. After the forage in the rear bin c2 is formed and the net - winding and bale - unloading are completed, the lower bin c3 returns to its original position and the front bin c1 is opened, so that the forage continues to enter the rear bin c2 for forming. Compared with the prior art, through the continuous - operation transmission structure c4 of the double - bin, the working efficiency of the round - bale machine is greatly improved.

[0037] Optionally, as Figure 2 shown in the figure Figure 2 is a schematic diagram of a double - bin continuous - operation transmission mechanism in the open - state of the lower bin in the embodiment of the present utility model. In the embodiment of the present utility model, the transmission structure c4 includes a chain mechanism c41, a front - bin transmission mechanism c42 and a lower - bin transmission mechanism c43. In the following part of the embodiment of the present utility model, the above - mentioned transmission structure c4 will be described in detail.

[0038] Optionally, as Figure 3As shown in the figure, the chain mechanism c41 includes: a main drive chain c411, which is connected to the power mechanism; here, the power mechanism refers to a tractor or other external power that drives the rotation of the main drive chain c411 through a sprocket; a front bin chain c412, which is power-connected to the main drive chain c411; a left lower bin chain c413, which is power-connected to the main drive chain c411; a right lower bin chain c414, which is power-connected to the main drive chain c411; and a rear bin chain c416, which is power-connected to the main drive chain c411. In the embodiments of the present invention, power is transmitted to the front bin chain c412, the left lower bin chain c413, and the right lower bin chain c414 through the main drive chain c411. In addition, in the embodiments of the present invention, the occurrence of tooth skipping and tooth disengaging can be prevented by adding a tension constraint to the chain.

[0039] Optionally, as Figure 4 shown in the figure Figure 4 is a schematic structural diagram of the other side of a transmission mechanism with a double bin that can operate continuously in the embodiments of the present invention. In the embodiments of the present invention, the chain mechanism c41 further includes a lower bin chain c415, and the lower bin chain c415 is power-connected

[0040] to the left lower bin chain c413. Through the power connection between the lower bin chain c415 and the left lower bin chain c413, the coordination of the movement of the lower bin is further enhanced.

[0041] Optionally, as Figure 5 shown in the figure, the front bin transmission mechanism c42 includes a plurality of short-axis rollers c421 and a long-axis roller c422, and the front bin transmission mechanism c42 makes an opening and closing movement around the long-axis roller c422. Specifically, the short-axis rollers c421 are arranged in two arcs, which respectively form the top of the front bin chamber c1 and the upper left top of the rear bin chamber c2, and the long-axis roller c422 is arranged at the top of the front bin chamber c1. Through the setting of this structure, as Figure 1 shown in the figure, when the front bin is opened, the short-axis rollers c421 arranged in an arc on the right side push the bale towards the right and into the rear bin chamber c2 while opening. In addition, when returning, the bale entering the rear bin chamber c2 can be squeezed. Through the setting of this structural form, the convenience and reliability of changing the bin can be improved. In some embodiments of the present invention, there are 10 short-axis rollers c421, and the maximum rotation angle of the front bin transmission mechanism c42 is 105°. It should be noted here that the opening of the front bin chamber c1 can be realized by means of a hydraulic cylinder or the like.

[0042] Optionally, as Figure 6As shown in the figure, the lower bin drive mechanism c43 includes a feeding reinforcement roller c431 and a double-shaft drum c432. The double-shaft drum c432 is arranged near the bottom of the front bin c1. A plurality of feeding reinforcement rollers c431 are arranged in parallel and extend in the feeding direction. The lower bin drive mechanism c43 makes an opening and closing movement centered on the double-shaft drum c432. Specifically, as shown in Figure 2 As shown in the figure, it is the structural form when the lower bin c3 rises. As shown in Figure 1 As shown in the figure, it is the structural schematic diagram when the lower bin c3 returns to its original position. When the lower bin rises, it can prevent the forage from entering the rear bin c2, and make the forage preformed in the front bin c1. After the forage is completely formed and the net wrapping and bale discharging are completed, the front bin c1 is opened and the lower bin c3 returns to its original position at the same time, as shown in Figure 1 As shown in the figure, at this time, the preformed bale in the front bin c1 is transferred to the rear bin. Since the lower bin c3 has returned to its original position, the forage can continue to be compacted and formed in the rear bin c2. In the embodiment of the present invention, the rotation angle of the lower bin drive mechanism c43 is 33°. In addition, it should be pointed out here that the density of the bale in the front bin can be guaranteed by presetting the pressure in the front bin c1. When the front bin c1 is opened, a buffer device such as a cylinder can be added to reduce the impact force on the cantilever when the front bin c1 is lifted.

[0043] In the embodiment of the present invention, a round baler is also provided, which includes the drive mechanism of the double-bin continuous operation described in any one of the above.

[0044] Application scenario of an exemplary embodiment:

[0045] As shown in Figures 1 to 6 As shown in the figure, when the forage enters the front bin c1 for preforming, the front bin c1 remains closed, and the lower bin c3 rises. After the forage is picked up, it is preformed in the front bin, and the lower feeding reinforcement roller c431 accelerates the forming of the bale; when the density of the bale in the front bin c1 reaches the set value, the system controls the lower bin c3 to return to its original position and opens the front bin c1, as shown in Figure 1As shown in the figure, when the front bin c1 is opened, the roller applies a thrust to the bale to facilitate the smooth transfer of the bale in the front bin c1 to the rear bin c2; then the front bin c1 is closed, and the picked forage continues to enter the rear bin c2 through the lower bin c3 for further forming. When the bale density in the rear bin c2 reaches the set value, the lower bin rises to close the path leading to the rear bin c2, and the forage continues to be pre-formed in the front bin c1. At the same time, the net winding operation is carried out in the rear bin c2. When the net winding operation is completed, the cutting knife drops to cut the net rope, and the rear bin c2 is opened for bale unloading operation. After the bale unloading is completed, the rear bin is closed, and the above operations are repeated; in the embodiment of the present invention, compared with the single-bin structure, the forming time of the bale in the double-bin structure is about 25-35 s, which is much less than that of the single-bin structure in terms of operation efficiency, so the single-bin structure can be completely replaced. Of course, it should also be pointed out here that in the embodiment of the present invention, a suitable logic control program can also be written. To ensure that the transmission structures do not interfere with each other during operation, the logical sequence between the bin doors needs to be strictly executed according to the setting; at the same time, it is also necessary to meet the actual working motion states of each bin. For example, the front bin needs to rise quickly and descend slowly during actual operation. Compared with the single-bin baler, a perfect logic control can make the machine adapt to complex working conditions.

[0046] The above description and the drawings fully illustrate the embodiments of the present invention so that those skilled in the art can practice them. Other embodiments may include structural and other changes. Embodiments only represent possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations can vary.
