DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0030] Example 1

[0031] A fallen leaf processing device for forestry, such as Figure 1-10 As shown, it includes a mounting shell 1 and a crusher 2; the crusher 2 is mounted on one side of the mounting shell 1, and the fallen leaves are crushed by the crusher 2;

[0032] It also includes a horizontal screen plate 3, an inclined screen plate 4 and a transfer assembly; the horizontal screen plate 3 and the inclined screen plate 4 are fixedly connected to the upper part of the installation shell 1, and the left side of the horizontal screen plate 3 is fixedly connected to the inclined screen plate 4; the horizontal screen plate 3 is provided with a first slot 3a, and the inclined screen plate 4 is provided with a second slot 4a, and the crushed stones in the fallen leaves are screened out through the first slot 3a and the second slot 4a to prevent the crusher 2 from being damaged by the crushed stones during crushing; the transfer assembly is installed in the middle part of the installation shell 1, and the fallen leaves are transported to the crusher 2 in an orderly manner through the transfer assembly to prevent the crusher 2 from being in idling or high-load operation.

[0033] The transfer assembly includes a rotating shaft 5 and an arc-shaped lever 6; the rotating shaft 5 is rotatably connected to the mounting shell 1, and one end of the rotating shaft 5 is fixedly connected to the motor drive shaft; the rotating shaft 5 is fixedly connected to the arc-shaped lever 6, and the gravel stuck in the first slot 3a and the second slot 4a is picked out by the arc-shaped lever 6, and the fallen leaves are transferred to the crusher 2 by the arc-shaped lever 6.

[0034] The diameter of the arc-shaped lever 6 is smaller than the slot widths of the first slot 3a and the second slot 4a, so that the arc-shaped lever 6 can better pick out the stuck gravel.

[0035] It also includes a baffle 7, which is rotatably connected to the left part of the inclined screen plate 4; an elastic member 7a is fixedly connected to the lower side of the baffle 7, and the elastic member 7a is fixedly connected to the inclined screen plate 4; the left part of the inclined screen plate 4 has a limiting portion 4b, which is used to resist the baffle 7 and limit the baffle 7 from rotating upward.

[0036] The arc-shaped lever 6 has a first arc-shaped portion 6a and a second arc-shaped portion 6b. The baffle plate 7 is pressed down by the first arc-shaped portion 6a, and the baffle plate 7 is maintained in the pressed state by the second arc-shaped portion 6b.

[0037] The width of the baffle 7 is set to 2-4m.

[0038] In order to overcome the problem of idling and high-load operation caused by feeding problems in the existing fallen leaf crusher 2; and at the same time to overcome the problem that gravel in the fallen leaves may damage the crusher 2, the present invention is specially proposed.

[0039] When the present invention is working, workers send fallen leaves into the installation shell 1, and the fallen leaves fall on the horizontal sieve plate 3 and the inclined sieve plate 4 for temporary storage. The crushed stones in the fallen leaves are screened out through the first slots 3a and the second slots 4a provided on the horizontal sieve plate 3 and the inclined sieve plate 4. At the same time, the motor drives the rotating shaft 5 to rotate, so that the arc-shaped lever 6 rotates counterclockwise. When the arc-shaped lever 6 is transferred to the horizontal sieve plate 3 and the inclined sieve plate 4 area, the arc-shaped lever 6 passes through the first slot 3a and the second slot 4a; as the arc-shaped lever 6 rotates, the arc-shaped lever 6 moves the horizontal sieve plate 3 and the inclined sieve plate 4 on the horizontal sieve plate 3 and the inclined sieve plate 4. The fallen leaves are transferred to the crusher 2 in batches continuously. Since the size of the arc lever 6 is determined, the number of fallen leaves fed into the crusher 2 through the arc lever 6 each time is not much different. Therefore, there will not be no fallen leaves to be crushed or a large number of fallen leaves to be crushed in the crusher 2 at a certain time. At the same time, when the arc lever 6 passes through the first slot 3a and the second slot 4a, the gravel stuck in the first slot 3a and the second slot 4a will be picked out to avoid blockage and affect the gravel falling from the first slot 3a and the second slot 4a to separate from the fallen leaves. Even if the staff pours a lot of fallen leaves into the present invention at one time, the present invention uses the arc lever 6 to feed the material, and the inclined screen plate 4 is tilted to prevent the gravel from moving to the crusher 2, and the gravel will not enter the crusher 2 due to a large amount of feed.

[0040] Furthermore, there are some stones with larger volume that cannot fall down from the first slot 3a and the second slot 4a, so these stones will be transferred to the baffle 7 when the arc lever 6 rotates. Figure 7 As shown in the figure, when the arc lever 6 rotates, the first arc portion 6a will contact the baffle 7 and press the baffle 7 downward, so that the baffle 7 flips downward. When the baffle 7 flips downward, the stones on its surface will fall downward. As the arc lever 6 separates from the baffle 7, the baffle 7 recovers through the elastic member 7a. Figure 4 In the state shown, the limiting portion 4b and the elastic member 7a cooperate to keep the baffle 7 in this state.

[0041] Furthermore, if Fig. 9 As shown, the second arc-shaped portion 6b can keep the baffle 7 open for a period of time. In this way, when there is a lot of crushed stone, some crushed stone that has passed the baffle 7 and is located on the upper left surface of the inclined screen plate 4 cannot be transferred in such a short time when the baffle 7 is turned over. Therefore, keeping the baffle 7 open for a period of time can facilitate the transfer of this part of the crushed stone.

[0042] It should be noted that since the crusher 2 is installed on the side of the mounting shell 1, the inclined screen plate 4 will vibrate due to the operation of the crusher 2, which is conducive to the downward transfer of crushed stone during the opening time of the baffle 7. It should also be noted that the width of the baffle 7 is set to 2-4m to prevent a large amount of fallen leaves from falling downward when the baffle 7 is rotated downward to open.

[0043] It should be noted that, by tilting the inclined screen plate 4 , the crushed stones can slide down automatically on its surface, thereby preventing the crushed stones from accumulating on the upper left part of the inclined screen plate 4 and being transferred to the crusher 2 .

[0044] Example 2

[0045] On the basis of Example 1, Figure 1-10 As shown, a guide plate 8 is provided at the connection between the inclined screen plate 4 and the left shell of the mounting shell 1 to transfer the fallen leaves to the crusher 2.

[0046] The front shell of the installation shell 1 is detachably provided with the air blower 101; the rear shell of the installation shell 1 is detachably provided with the fixing ring 102, and a plurality of fishing rods 102a are arranged on the fixing ring 102. The broken leaf collection bag is put on the fixing ring 102 through the fishing rods 102a. When the gravel falls downward, some broken leaves will also fall with it. These broken stones and broken leaves will pass between the air blower 101 and the fixing ring 102. The collection bag of broken leaves is put on the fixing ring 102 through the fishing rods 102a in advance, and the air blower 101 is controlled to supply air in the direction of the fixing ring 102, so as to blow the broken leaves toward the collection bag, thereby realizing the collection of broken leaves.

[0047] A collecting box 201 is inserted at the bottom of the mounting shell 1 , and the crushed stones falling downward are collected by the collecting box 201 . When needed, the collecting box 201 can be taken out through a handle on the collecting box 201 .

[0048] The pulverizer 2 further comprises a shielding cover 301 , which is fixedly connected to the upper part of the pulverizer 2 , so as to prevent the fallen leaves from splashing out when being crushed.

[0049] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
