Description

Technical Field

[0001] The present invention relates to the technical field of tea picking machines, and in particular to a tea picking net covering machine. Background Art

[0002] A Japanese patent with the patent number JP6030500B2 discloses a winding device for a covering material such as a lawn cloth that directly covers a tea ridge, which is a new type of winding and unwinding device that can wind particularly efficiently and neatly. To achieve the multi-functionality of agricultural machinery, it is usually connected to the power component of a tea picking machine to make a tea picking net covering machine. However, this winding device still has the following disadvantages and deficiencies: A single roll of covering net generally cannot be accurately adapted to tea ridges of different lengths. Therefore, a single roll of covering net generally has a certain margin design. When the net covering machine finishes laying a tea ridge, the covering net needs to be cut. The cut covering net can only be singly adapted to that section of the tea ridge, and can only be applied to the covering of that section of the tea ridge after being recycled. Therefore, the existing net rolls are difficult to achieve efficient recycling; In addition, when the covering net covering the tea ridge is recycled, one end of the net needs to be fixed on the reel in advance, and then collected by rotating the reel. The process is relatively complicated and labor-consuming. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a tea picking net covering machine. By means of a separable reel, the reel and the remaining covering net are directly discarded after net covering, realizing the integrity of the covering net. At the same time, a clamping mechanism realizes the limit rotation of the remaining covering net, avoiding the problem of single covering caused by cutting the covering net.

[0004] To solve the above technical problems, the present invention is solved by the following technical solutions: A tea picking net covering machine includes a traveling part and a net laying frame arranged behind the traveling part; A separable reel is arranged on the net laying frame, and a covering net is wound around the reel; Guide grooves for the reel to slide symmetrically are arranged on both sides of the net laying frame. A separation plate rotatably arranged at the bottom of the net laying frame is connected to the guide grooves. The separation plate is connected with a first push rod. After the separation plate rotates, the reel is separated from the net laying frame; Guide blocks are symmetrically arranged at both ends of the reel, and clamping plates that are slidably matched with the guide blocks and clamp the outer wall of the net laying frame. Both ends of the clamping plates are slidably connected to the guide blocks through guide rods; A first clutch that cooperates with the guide blocks is arranged on the reel. A number of pin holes are arranged on the first clutch. A locking pin that is slidably driven by the guide rod is slidably arranged on the guide block. After the guide rod slides, it drives the locking pin to slide so that the guide block and the reel form an integral body, so that the covering net remaining on the reel is limited by the clamping plate.

[0022] The following further describes the present invention in detail in conjunction with the accompanying drawings and the detailed implementation manners: Refer to Figures 1-7 .

[0023] A tea picking net covering machine includes a traveling part 1 and a net laying frame 2 arranged behind the traveling part 1, that is, the net laying frame 2 is arranged behind the traveling part 1 in the traveling direction. A cutter for shearing tea leaves is arranged in front of the traveling part 1. After the tea leaves are sheared, a covering net is laid on the tea ridges through the net laying frame 2.

[0024] A separable reel 201 is arranged on the net laying frame 2, and a covering net 200 is wound around the reel 201, that is, the covering net 200 is stored in a roll and placed on the net laying frame 2. The net laying frame 2 is used for laying and storing the covering net 200.

[0025] Axle cores 7 are symmetrically arranged at both ends of the reel 201. The axle cores 7 adopt hexagonal axles. A first clutch 3 is slidably arranged on the axle cores 7, and a hexagonal hole adapted to the hexagonal axle is provided at the center of the first clutch 3.

[0026] A tension spring 302 is arranged between the first clutch 3 and the end wall of the reel 201, that is, in the initial state, the first clutch 3 is pulled by the tension spring 302 and thus is located on one side close to the end wall of the reel 201. A clutch tooth part is arranged at one end of the first clutch 3 away from the reel 201, and a clamping groove 303 is arranged on the outer wall of the end close to the reel 201. The clamping groove 303 is an annular groove, and a guide block 205 is rotatably arranged on the clamping groove 303, that is, the guide block 205 is rotatably clamped on the first clutch 3 through the clamping groove 303.

[0027] On both sides of the laying grid frame 2, guiding grooves 202 for the sliding of the reel 201 are symmetrically arranged. Specifically, the guiding grooves 202 are vertical long grooves with open upper ends, and the groove width is adapted to the outer circle of the first clutch 3. Both ends of the reel 201 are slidably clamped into the guiding grooves 202 through the first clutch 3 to complete the assembly of the reel and the laying grid frame 2. A connecting plate 8 is arranged at the upper end of the guiding groove 202, and the connecting plate 8 is detachably fixedly connected to the laying grid frame 2. When installing the reel 201, the connecting plate 8 is removed for installation, and after being installed, the connecting plate 8 is reinstalled to seal the upper opening of the guiding groove 202 for fixed connection.

[0028] On both sides of the end face of the guiding groove 202 away from the reel 201, slide rails 214 are symmetrically arranged, as Figures 2-4 shown. The upper section of the slide rail 214 is a straight face, and the lower section is inclined outward away from the reel 201 to form a driving face 216. A sliding portion 215 matching the slide rail 214 is arranged on the guiding block 205. That is, when the first clutch 3 slides into the guiding groove 202, the sliding portion 215 on the guiding block 205 comes into contact and cooperation with the slide rail 214, and an extrusion face 217 for extrusion cooperation with the driving face 216 is arranged on the sliding portion 215. After the extrusion face 217 on the sliding portion 215 slides and cooperates with the driving face 216, the guiding block 205 can be driven to slide towards the end away from the reel 201, thereby synchronously driving the clutch teeth portion of the first clutch 3 to slide towards the end away from the reel 201.

[0029] On any side of the laying grid frame 2, a second clutch 4 matching the first clutch 3 is arranged. The second clutch 4 is arranged on the side of the guiding groove 202 away from the reel 201 and is coaxially arranged with the center of the lower arc of the guiding groove 202. When the guiding block 205 slides down on the slide rail 214, the first clutch 3 slides into the lower arc groove of the guiding groove 202, so that the clutch teeth portion is butted against the clutch teeth portion of the second clutch 4 to achieve meshing.

[0030] A driving shaft 5 is arranged on the laying grid frame 2. The driving shaft 5 is a hexagonal shaft. The second clutch 4 is slidably arranged on the driving shaft 5. The driving shaft 5 is connected with a driving motor. When the driving motor is started, the driving shaft 5 can drive the second clutch 4 to rotate, thereby synchronously driving the first clutch 3 engaged with it to rotate. Further, the reel 201 is driven to rotate to realize the laying and storage of the covering net 200. A hexagonal hole is arranged on the second clutch 4, and a clamping groove is arranged on the outer wall of the second clutch 4. A clutch plate 601 rotatably matched with the clamping groove is arranged on the clamping groove. A second push rod 6 is arranged on the laying grid frame 2. The push rod end of the second push rod 6 is fixedly connected with the clutch plate 601, so that the second clutch 4 can be driven to slide relative to the first clutch 3 to realize meshing and disengagement with it, and does not affect the transmission cooperation between the driving shaft 5 and the second clutch 4.

[0031] A separating plate 203 which is rotatably arranged at the bottom of the laying net rack 2 and is connected to the guiding groove 202 is provided. The bottom of the guiding groove 202 is arc-shaped and arranged on the separating plate 203. When the separating plate 203 rotates, the bottom of the guiding groove 202 can be opened, so that both ends of the reel 201 slide downward and are separated from the laying net rack 2.

[0032] One side of the separating plate 203 is provided with a rotating shaft 9. The rotating shaft 9 is rotatably arranged on the plate body at the bottom of the laying net rack 2. One end of the rotating shaft 9 penetrates through the wall of the laying net rack 2 and is fixedly provided with a rocker arm 901. One end of the rocker arm 901 is fixed to the rotating shaft 9, and the other end is rotatably connected to the push rod end of the first push rod 204. After the first push rod 204 pushes the rocker arm 901 to rotate, the separating plate 203 rotates to open the bottom of the guiding groove 202, so that the bottom of the guiding groove 202 is opened. Then, the second push rod 6 drives the second clutch 4 to slide, so that it is disengaged from the first clutch 3, and the reel 201 slides out of the laying net rack 2 from the bottom of the guiding groove 202, realizing the separation of the reel 201 from the laying net rack 2.

[0033] In order to make the remaining covering net 200 and the main body of the reel 201 relatively fixed and not be pulled after the reel 201 is separated from the laying net rack 2, in this embodiment, clamping plates 206 which clamp the outer wall in the axial direction of the reel 201 are slidably arranged on the guiding blocks 205 arranged at both ends of the reel 201. Telescopic extension plates 10 are symmetrically arranged at both ends of the clamping plates 206. Guide rods 207 are fixedly arranged on the extension plates 10. The guide rods 207 penetrate through the guiding blocks 205, so that both ends of the clamping plates 206 are in guiding and sliding connection with the guiding blocks 205 through the guide rods 207.

[0034] A plurality of pin holes 301 are arranged on the first clutch 3. The pin holes 301 are uniformly arranged in the clamping groove 303 and penetrate through the middle hole body of the first clutch 3. A locking pin 208 which is in driving cooperation with the guide rod 207 is vertically slidably arranged on the guiding block 205. As Figure 3 shown, a concave hole 211 which is matched with the upper end of the locking pin 208 is arranged on the guide rod 207. A receiving cavity 212 which is matched with the lower end of the locking pin 208 is arranged in the guiding block 205. That is, initially, the lower end of the locking pin 208 is placed in the receiving cavity 212, and the upper end abuts against the concave hole 211. A sliding hole is arranged at the bottom of the receiving cavity 212. The lower end of the locking pin 208 is placed in the sliding hole. A second spring 213 is arranged between the locking pin 208 and the bottom of the lower end cavity of the receiving cavity 212.

[0035] A guiding hole 209 which is matched with the guide rod 207 is arranged on the guiding block 205. A first spring 210 is arranged between the clamping plate 206 and the guiding block 205. Specifically, both ends of the first spring 210 are respectively connected to the guiding block 205 and the extension plate 10.

[0036] When the guiding rod 207 is on the net laying frame 2, through the limitation of the clamping plate 206 on the outer wall of the net laying frame 2, the upper end of the locking pin 208 is in a position corresponding to and mating with the concave hole 211. When the reel 201 is separated from the net laying frame 2, the clamping plate 206 releases the limitation. After the guiding rod 207 slides relative to the guiding block 205, it drives the locking pin 208 to slide after squeezing the second spring 213, so that the lower end of the locking pin 208 is inserted into any pin hole 301 of the first clutch 3, thereby making the guiding block 205 and the reel 201 an integral whole. At this time, the clamping plate 206 and the reel 201 are in a relatively fixed state, and the covering net 200 remaining on the reel 201 is limited by the clamping plate 206, thus preventing the remaining covering net 200 from continuing to extend.

[0037] Method of using a tea picking covering net machine as described above: The reel 201 and the covering net 200 wound thereon are in a roll shape and are clamped into the guiding groove 202 through the outer walls at both ends of the first clutch 3, and the sliding part 215 of the guiding block 205 is in contact and mating with the sliding rail 214. At this time, the clamping plate 206 is placed outside the net laying frame 2 and slides in contact with its outer wall; The guiding block 205 drives the first clutch 3 to slide away from the reel 201 by the abutting and mating of the extrusion surface 217 on the sliding part 215 and the driving surface 216. Subsequently, the engaging tooth parts on the first clutch 3 are engaged with the engaging tooth parts on the second clutch 4, and the traveling part 1 of the tea picking machine travels. The driving motor starts to drive the driving shaft 5 to rotate, and the covering net 200 is covered on the tea ridges after picking through the rotation of the reel 201; When reaching the end of the tea ridge, the driving motor stops. At the same time, the second push rod 6 starts to slide the second clutch 4 away from the first clutch 3 to disengage them. Subsequently, the first push rod 204 drives the separating plate 203 to rotate, opening the bottom of the guiding groove 202. Further, the reel 201 together with the remaining covering net 200 is separated from the net laying frame 2 as a whole; Subsequently, the clamping plate 206 slides towards the guiding block 205 through the first spring 210, and the guiding rod 207 drives the locking pin 208 to slide downward to cooperate with the pin hole 301 on the first clutch 3, so that the reel 201 and the guiding block 205 are locked relative to each other circumferentially, that is, they cannot rotate relative to each other. The entire reel 201 drops to the end of the tea ridge, and the remaining covering net 200 is still wound on the reel 201 in a roll shape through the limitation of the clamping plate 206; When the covered covering net 200 needs to be stored, only the reel 201 at the end of the tea ridge needs to be reinstalled into the guiding groove 202 and then cooperate with the second clutch 4, and the driving motor is reversed to store the covering net 200.
