Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural residual film recycling, in particular to a potato field residual film recycling equipment. BACKGROUND

[0002] Residual film recycling is crucial in agriculture because residual film is difficult to degrade, long-term accumulation can hinder soil aeration and water permeability, affect crop root growth and nutrient absorption, and reduce land productivity. In addition, residual film may be mistakenly eaten by livestock, leading to health problems, or migrate with the wind, causing environmental pollution. Effective recycling of residual film helps maintain the ecological balance of farmland and ensures sustainable agricultural development.

[0003] In the prior art, patent CN 108934228 A discloses a typical residual film recycling device, which has a film picking roller, a residual film conveying and soil removing device, and a film collecting box arranged from front to back. In this device, the residual film conveying and soil removing device is a traditional rod chain structure, and the soil removal effect is poor during conveying, which increases the difficulty of subsequent residual film treatment because the collected residual film still contains a lot of soil impurities. In patent CN 118715897 A, a knocking mechanism is arranged below the rod chain, which can improve the soil removal effect, but the overall soil removal effect is limited because the knocking effect on the residual film is weak. SUMMARY

[0004] The present application provides a potato field residual film recycling equipment that can improve the vibration soil removal effect of residual film and reduce the soil content in residual film.

[0005] Technical solution: To achieve the above purpose, the potato field residual film recycling equipment of the present application comprises a rack, a film picking roller, a chain harrow mechanism and a collecting box installed on the rack; the chain harrow mechanism comprises multiple groups of chain mechanisms arranged in parallel;

[0006] All chain mechanisms contained in the chain harrow mechanism include first chain mechanism and second chain mechanism, and the two chain mechanisms are staggered;

[0007] The first chain mechanism comprises a first chain, and the high and low ends of the first chain have a first high chain wheel and a first low chain wheel, respectively;

[0008] The second chain mechanism comprises a second chain, and the high and low ends of the second chain have a second high chain wheel and a second low chain wheel, respectively;

[0009] All the first low chain wheels and the second low chain wheels are staggered mounted on a first shaft, and the first low chain wheels and the second low chain wheels are rotatably mounted relative to the first shaft; all the first high chain wheels are mounted on a second shaft, and all the second high chain wheels are mounted on a third shaft; the first high chain wheels and the second high chain wheels are fixedly mounted relative to the second shaft and the third shaft respectively.

[0010] The second shaft and the third shaft are mounted on a rotating frame, and the rotating frame can make reciprocating swing movement.

[0011] With the above structure, by arranging the staggered first chain mechanism and the second chain mechanism, and coaxially mounting the low chain wheels of the two, and mounting the high chain wheels of the two on the second shaft and the third shaft respectively, when picking up the work, by rotating the rotating frame, the second shaft and the third shaft can be alternately lifted, and the two chain mechanisms can beat the residual film conveyed on the chain harrow mechanism, and the farther the residual film goes, the greater the beating force on the residual film, which can fully remove the soil and other impurities on the residual film, so that the soil content of the collected residual film is less, and subsequent processing is facilitated.

[0012] Further, the chain harrow mechanism further comprises a first motor and a rotating wheel driven to rotate by the first motor, the rotating wheel has a pin shaft, the rotating frame has a strip-shaped hole, and the pin shaft is arranged in the strip-shaped hole. In this way, the rotation of the first motor can drive the rotating frame to reciprocate.

[0013] Further, the chain harrow mechanism further comprises a gear set establishing a transmission relationship between the second shaft and the third shaft; one of the first chain mechanism and the second chain mechanism is indirectly driven to rotate by a PTO output shaft of a tractor.

[0014] Further, the first chain mechanism further comprises a first tensioning wheel, and all the first tensioning wheels corresponding to the first chain mechanism are rotatably mounted on a fourth shaft; the fourth shaft is connected to the frame through a first elastic tensioning mechanism.

[0015] Further, the second chain mechanism further comprises a second tensioning wheel, and all the second tensioning wheels corresponding to the second chain mechanism are rotatably mounted on a fifth shaft; the fifth shaft is connected to the frame through a second elastic tensioning mechanism.

[0016] The fourth shaft and the fifth shaft are arranged staggered, so that all the first tensioning wheels and all the second tensioning wheels can be tensioned respectively and do not interfere with each other.

[0017] Further, anti-skid teeth are fixed on all the first chains and all the second chains at equal intervals, and the anti-skid teeth can prevent the residual film from slipping relative to the first chains and the second chains during conveying the residual film.

[0018] Beneficial effects: the potato field residual film recycling equipment has the beneficial effects that

[0019] By setting the staggered first chain mechanism and second chain mechanism, and coaxially installing the low chain wheels of the two, and respectively installing the high chain wheels of the two on the second shaft and the third shaft, when performing the picking operation, by rotating the rotating frame, the second shaft and the third shaft can be alternately lifted, the two chain mechanisms can beat the residual film conveyed on the chain harrow mechanism, and the farther the residual film goes, the greater the beating force on the residual film, so that the soil and other impurities on the residual film can be fully removed, so that the collected residual film has less soil and impurities, and subsequent processing is facilitated.

DETAILED DESCRIPTION

[0028] The application will be further described below in combination with the drawings.

[0029] As Figure 1 The potato field residue film recovery equipment includes a rack 1, a film picking roller 2, a chain harrow mechanism 3 and a collection box 4 are installed on the rack 1; the chain harrow mechanism 3 includes a plurality of groups of chain mechanisms arranged in parallel;

[0030] As Figures 2 to 4 The chain harrow mechanism 3 includes two kinds of first chain mechanism 31 and second chain mechanism 32, and the two kinds of chain mechanisms are staggered arranged;

[0031] The first chain mechanism 31 includes a first chain 31a, and the first chain 31a has a first high chain wheel 31b and a first low chain wheel 31c at the high and low ends respectively;

[0032] The second chain mechanism 32 includes a second chain 32a, and the second chain 32a has a second high chain wheel 32b and a second low chain wheel 32c at the high and low ends respectively;

[0033] All the first low chain wheels 31c and the second low chain wheels 32c are staggered installed on a first shaft 33, and the first low chain wheels 31c and the second low chain wheels 32c are rotatably installed relative to the first shaft 33; all the first high chain wheels 31b are installed on a second shaft 34, and all the second high chain wheels 32b are installed on a third shaft 35; the first high chain wheels 31b and the second high chain wheels 32b are fixedly installed relative to the second shaft 34 and the third shaft 35 respectively;

[0034] The second shaft 34 and the third shaft 35 are both installed on a rotating frame 36, and the rotating frame 36 can make reciprocating swing movement.

[0035] With the above structure, by arranging the first chain mechanism 31 and the second chain mechanism 32 staggered, and the low chain wheels of the two coaxially installed, and the high chain wheels of the two respectively installed on the second shaft 34 and the third shaft 35, when picking up, by rotating the rotating frame 36, the second shaft 34 and the third shaft 35 can be alternately lifted, and the two kinds of chain mechanisms can beat the residue film conveyed on the chain harrow mechanism 3, and the farther the residue film goes, the greater the beating force on the residue film, which can fully remove the soil and other impurities on the residue film, so that the collected residue film has less soil and impurities, and the subsequent processing is facilitated. Figure 6 The state that the second chain 32a is higher than the first chain 31a is shown.

[0036] Specifically, the chain harrow mechanism 3 further includes a first motor 37 and a rotating wheel 38 driven to rotate by the first motor 37, as Figure 5As shown, the rotating wheel 38 has a pin 38a, and the rotating frame 36 has a strip hole 36a, and the pin 38a is placed in the strip hole 36a. In this way, the operation of the first motor 37 can drive the rotating frame 36 to swing back and forth.

[0037] As shown in the figure, the chain rake mechanism 3 further includes a gear set 39 that establishes a transmission relationship between the second shaft 34 and the third shaft 35; one of the first chain mechanism 31 and the second chain mechanism 32 is indirectly driven by the PTO output shaft of the tractor.

[0038] like Figure 7 As shown, the gear set 39 includes a circular gear set 39a and a non-circular gear set 39b. The second shaft 34 transmits power to the transition shaft 39c through the circular gear set 39a, and the transition shaft 39c transmits power to the third shaft 35 through the non-circular gear set 39b. The number of teeth of the two gears constituting the circular gear set 39a is equal, and the number of teeth of the two non-circular gears constituting the non-circular gear set 39b is also equal; in this way, the operation of the second shaft 34 and the third shaft 35 is asynchronous, which can cause the residual film on the chain rake mechanism 3 to vibrate parallel to the conveying direction, further increase the vibration of the residual film, and improve the efficiency of shaking off dirt.

[0039] like Figure 1 As shown, the first chain mechanism 31 further includes a first tensioning wheel 310 , and all the first tensioning wheels 310 corresponding to the first chain mechanisms 31 are rotatably mounted on a fourth shaft 311 ; the fourth shaft 311 is connected to the frame 1 via a first elastic tensioning mechanism 312 .

[0040] The second chain mechanism 32 further includes a second tensioning wheel 313 . The second tensioning wheels 313 corresponding to all the second chain mechanisms 32 are rotatably mounted on a fifth shaft 314 . The fifth shaft 314 is connected to the frame 1 via a second elastic tensioning mechanism 315 .

[0041] The fourth shaft 311 and the fifth shaft 314 are staggered so that all the first tensioning wheels 310 and all the second tensioning wheels 313 can be tensioned separately without interfering with each other.

[0042] Preferably, anti-slip teeth 316 are fixed at equal intervals on all the first chains 31a and all the second chains 32a. The anti-slip teeth 316 can prevent the residual film from sliding relative to the first chain 31a and the second chain 32a during the conveyance of the residual film.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
