Description

Technical Field

[0001] The present invention relates to the technical field of thorn-removing and leaf-removing machines, and particularly to a double-shaft horizontal fresh flower thorn-removing and leaf-removing machine. Background Art

[0002] After fresh flowers are picked, it is necessary to remove the branches and leaves at the lower part. Especially for some thorny fresh flowers, such as roses, Chinese roses, and multiflora roses, the thorns at the lower part also need to be removed. And subsequently, sorting needs to be carried out according to the state of the flowers. The current methods are either to trim one by one with a knife and visually sort, or to use a thorn-removing and leaf-removing device to carry out thorn-removing and leaf-removing bundle by bundle, and then carry out the next process for sorting. Currently, there are intelligent online sorting devices that can automatically take pictures of the flowers and judge the state of the flowers based on image processing technology, and then carry out sorting. This online sorting device requires manual operation to hang the flower branches one by one on the conveying mechanism of the device. The existing thorn-removing and leaf-removing machines and online sorting devices are independent of each other, and the two cannot cooperate well. It requires manual operation twice, and the flower branches after thorn-removing and leaf-removing need to be transferred in the middle, resulting in high labor intensity, low efficiency, and easy damage to the flowers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a double-shaft horizontal fresh flower thorn-removing and leaf-removing machine, which can realize thorn-removing and leaf-removing operations, cooperate well with the sorting device, minimize manual operation as much as possible, improve work efficiency, and reduce labor intensity.

[0004] To solve the above technical problem, the technical solution of the present invention is a double-shaft horizontal fresh flower thorn-removing and leaf-removing machine, including a frame, and two parallelly arranged thorn-removing shafts rotatably installed between the frames; a thorn-removing roller is installed on each of the thorn-removing shafts; two spaced second support plates are installed on the top of the frame; a rotating shaft is rotatably installed at both ends of each second support plate; a synchronous pulley is installed at the lower part of each rotating shaft; the two synchronous pulleys on the same second support plate are connected by a synchronous belt; a flexible layer is wrapped on the outer wall of the synchronous belt; the part where the two flexible layers are in contact is directly above the gap between the two thorn-removing rollers.

[0005] Furthermore, a first driving component for driving the two groups of rotating shafts to rotate in opposite directions is installed on the two second support plates.

[0006] Furthermore, the first driving component includes an inverted U-shaped mounting frame fixedly installed on the upper part of one end of the two second support plates; gears meshing with each other are installed on the upper parts of the two rotating shafts located at one end of the mounting frame; a motor is installed above the mounting frame; the motor is connected to one of the rotating shafts through a coupling.

[0007] Furthermore, several second support columns are installed on the top of the mounting frame, and a top plate is installed on the top of the second support columns; the motor is installed on the top plate; two bearing sleeves are installed on the top of the mounting frame; the upper ends of the two rotating shafts equipped with the gears are rotatably connected to the bearing sleeves through bearings.

[0008] Furthermore, two first support plates arranged at intervals are fixedly connected to the top of the machine frame; several first support columns are installed at the upper ends of each of the first support plates; the upper ends of the first support columns are threaded; the upper ends of the first support columns penetrate through the second support plate and are locked by two locking nuts.

[0009] Furthermore, the first support columns are detachably installed at the upper ends of the first support plates.

[0010] Furthermore, a second driving assembly for driving the two threshing shafts to rotate is installed on the machine frame.

[0011] Furthermore, the second driving assembly includes a first pulley and a second pulley respectively installed on the two threshing shafts, a second mounting plate installed on the machine frame; a driving motor installed on the second mounting plate, a driving pulley installed on the driving motor, a first mounting plate installed on the machine frame; a tension pulley rotatably installed on the first mounting plate; a belt sequentially wrapping the driving pulley, the tension pulley, the second pulley, and the first pulley; the two threshing shafts are inclined, and the end close to the belt is lower than the other end.

[0012] Furthermore, the machine frame includes a protective cover surrounding the threshing roller; the hole on the second mounting plate for installing the driving motor is a strip-shaped hole; the hole on the machine frame for installing the first mounting plate is a strip-shaped hole.

[0013] Furthermore, the threshing rollers are spirally distributed along the threshing shaft.

[0014] Furthermore, the lengths of several threshing rollers at the end of the threshing shaft away from the belt are less than the lengths of the remaining threshing rollers.

[0015] Furthermore, the synchronous belt and the synchronous belt pulley are both of toothed structures.

[0016] Advantages of the present invention: During operation, the flower branches are manually pushed one by one between the two flexible layers, and the lower part of the flower branches is inserted between the two groups of thorn-removing rollers. The flexible layers move along with the synchronous belt, and the flower branches clamped between the two flexible layers are driven to move.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Embodiment 1 A double-shaft horizontal flower thorns and leaves removing machine, as Figure 1-4 shown, includes a frame 1, and two relatively rotating thorns removing shafts 3 arranged in parallel and rotatably installed between the frames 1; a thorns removing roller 4 is installed on each thorns removing shaft 3; two second support plates 12 arranged at intervals are installed on the top of the frame 1; a rotating shaft 17 is rotatably installed at both ends of each second support plate 12; a synchronous pulley 15 is installed at the lower part of each rotating shaft 17; the two synchronous pulleys 15 on the same second support plate 12 are connected by a synchronous belt 19; a flexible layer 13 is wrapped on the outer wall of the synchronous belt 19; the contact part of the two flexible layers 13 is located directly above the gap between the two thorns removing rollers 4.

[0022] During operation, the flower branches are manually pushed into the space between the two flexible layers 13 one by one, and the lower part of the flower branches is inserted between the two groups of thorns removing rollers 4. The flexible layer 13 moves along with the synchronous belt 19, and the flower branches clamped between the two flexible layers 13 are driven to move. At the same time, the two groups of relatively rotating thorns removing rollers 4 perform thorns removing and leaves removing operations on the lower part of the flower branches until the flower branches are removed from the other end one by one.

[0023] Specifically, a first driving component for driving the two groups of rotating shafts 17 to rotate in opposite directions is installed on the two second support plates 12.

[0024] Specifically, the first driving component includes an inverted U-shaped mounting frame 16 fixedly installed on the upper part of one end of the two second support plates 12; gears 18 meshing with each other are installed on the upper parts of the two rotating shafts 17 located at one end of the mounting frame 16; a motor 21 is installed above the mounting frame 16; the motor 21 is connected to one of the rotating shafts 17 through a coupling. The motor 21 drives the rotating shaft 17 connected to it to rotate, drives the other rotating shaft 17 to rotate in the opposite direction through the two meshing gears 18, and drives the two synchronous belts 19 together with the flexible layer 13 to rotate in the opposite direction through the synchronous pulleys 15.

[0025] Specifically, a plurality of second support columns 20 are installed on the top of the mounting frame 16, and a top plate is installed on the top of the second support columns 20; the motor 21 is installed on the top plate; two bearing sleeves 22 are installed on the top of the mounting frame 16; the upper ends of the two rotating shafts 17 installed with the gears 18 are rotatably connected to the bearing sleeves 22 through bearings. By setting the bearing sleeves 22, the rotation of the rotating shaft 17 can be made more stable.

[0026] Specifically, two first support plates 11 arranged at intervals are fixedly connected to the top of the frame 1; several first support columns 24 are installed at the upper ends of each first support plate 11; the upper ends of the first support columns 24 are threaded; the upper ends of the first support columns 24 penetrate through the second support plate 12 and are locked by two lock nuts. The first support columns 24 and the first support plates 11 are provided to increase the distance between the second support plate 12 and the thorns roller 4, so as to adapt to fresh cut flowers with longer flower branches. And the position of the lock nut can be adjusted according to the length of the flower branch, so as to finely adjust the height of the second support plate 12.

[0027] Specifically, the first support columns 24 are detachably installed at the upper ends of the first support plates 11. When adjusting the lock nut cannot meet the length of the current flower branch, first support columns 24 of different lengths can be replaced to adapt to fresh cut flowers of different lengths.

[0028] Specifically, a second driving assembly for driving two thorns shafts 3 to rotate is installed on the frame 1.

[0029] Specifically, the second driving assembly includes a first belt pulley 8 and a second belt pulley 9 respectively installed on two thorns shafts 3, a second mounting plate 14 installed on the frame 1; a driving motor 5 installed on the second mounting plate 14, a driving belt pulley 25 installed on the driving motor 5, a first mounting plate 6 installed on the frame 1; a tension pulley 6 rotatably installed on the first mounting plate 6; a belt 7 sequentially wrapping the driving belt pulley 25, the tension pulley 6, the second belt pulley 9, and the first belt pulley 8; the two thorns shafts 3 are inclined, and the end close to the belt 7 is lower than the other end. The driving motor 5 drives the first belt pulley 8 and the second belt pulley 9 to rotate in opposite directions through the belt 7, so as to drive the two thorns shafts 3 to rotate in opposite directions. The thorns shafts 3 are inclined, on the one hand, it can increase the length of thorn removal at the lower end of the flower branch, and on the other hand, it can avoid interference of the belt 7 on the movement of the flower branch.

[0030] Specifically, the frame 1 includes a protective cover 23 surrounding the thorns roller 4; the hole on the second mounting plate 14 for installing the driving motor 5 is a strip-shaped hole; the hole on the frame 1 for installing the first mounting plate 10 is a strip-shaped hole. The tightness of the belt 7 can be adjusted by adjusting the installation position of the first mounting plate 10 and the installation position of the driving motor 5 on the second mounting plate 14.

[0031] Specifically, the thorns rollers 4 are spirally distributed along the thorns shafts 3. The spirally distributed thorns rollers 4 can, on the one hand, play a role in thorn removal and leaf removal for the flower branches, and on the other hand, play a role in pushing the lower part of the flower branches to move.

[0032] Specifically, for the convenience of feeding, the lengths of several thorns rollers 4 at the end of the thorns shaft 3 far from the belt 7 are less than the lengths of the remaining thorns rollers 4.

[0033] Specifically, both the synchronous belt 19 and the synchronous pulley 15 are of toothed structures, which can improve the transmission accuracy.

[0034] Embodiment 2 A double-shaft horizontal fresh flower thorns and leaves removing machine. Compared with Embodiment 1, the first driving assembly and the second driving assembly are different, and the rest of the structures are the same as those in Embodiment 1.

[0035] Specifically, the first driving assembly is two motors 21, and each motor 21 is respectively connected to a rotating shaft 17 on one of the second support plates 12.

[0036] Specifically, the two motors 21 are respectively installed on the two first support plates 11.

[0037] Specifically, the second driving assembly is composed of two driving motors 5, a driving pulley 25 installed on the driving motor 5, two tension pulleys 6, a first pulley 8 and a second pulley 9 installed on the two thorns removing shafts 3, a first belt wrapping the driving pulley 25, the tension pulley 6 and the first pulley 8, and a second belt wrapping the driving pulley 25, the tension pulley 6 and the second pulley 8, as Figure 6 shown. Such a setting can better avoid the interference of the belt on the movement of the flower branches.

[0038] Working principle: During operation, the motor 21 and the driving motor 5 are turned on. The motor 21 drives the rotating shaft 17 connected thereto to rotate, drives the other rotating shaft 17 to rotate reversely through two meshing gears 18, and drives the two synchronous belts 19 together with the flexible layer 13 to rotate reversely through the synchronous pulleys 15. The driving motor 5 drives the first pulley 8 and the second pulley 9 to rotate reversely through the belt 7, so as to drive the two thorns removing shafts 3 to rotate reversely. An operator manually pushes the flower branches one by one between the two flexible layers 13, with the flowers located above the flexible layer 13, and inserts the lower part of the flower branches between the two groups of thorns removing rollers 4. The upper part of the flower branches is clamped between the flexible layers 13 and is driven to move. The two groups of relatively rotating thorns removing rollers 4 perform thorns removing and leaves removing operations on the lower part of the flower branches until the flower branches are removed from the other end one by one. By installing an inclined receiving rack on the intelligent online sorting device, there is an opening in the middle of the receiving rack, and the opening of the receiving rack is aligned with the upper edge of one end of the contact surface of the flexible layer 13 in the present application, so that the flower branches after thorns removing and leaves removing can automatically move along the receiving rack to the intelligent online sorting device, as Figure 5 shown.

[0039] The unique structural design of the present application effectively coordinates the two processes of thorns removing and leaves removing and online sorting. Only one manual feeding is required to complete the thorns removing and leaves removing operation, which can be automatically transferred to the subsequent sorting device for continuous sorting operation, minimizing manual operation as much as possible, and reducing the original step of manually transferring the flower branches in the middle. While improving the work efficiency, the probability of damaging the flowers can be reduced.
