[0013] By adopting the above structure, this utility model has the following beneficial effects:
[0014] The first and second needle beds of this invention are arranged parallel to each other in the front and rear directions of the lawnmower. Several tufting needles are detachably installed at the bottom of the first and second needle beds respectively. Several first needle seats are detachably installed on the rear side of the first needle bed, and several second needle seats are detachably installed on the front side of the second needle bed. Each first and second needle seat is equipped with a vertically arranged tufting needle. The tufting needles installed on the first needle seats of the first needle bed and the tufting needles installed on the second needle seats of the second needle bed are staggered in the radial direction of the lawnmower. The first needle bed is driven by a third drive mechanism to move independently back and forth in the radial direction of the lawnmower. The second needle bed is driven by a fourth drive mechanism to move independently back and forth in the radial direction of the lawnmower. The oil tank is driven by an oil tank lateral movement mechanism to move back and forth in the front and rear directions of the lawnmower. With this structure, the first needle bed is driven to reciprocate laterally by the third drive mechanism, and the second needle bed is driven to reciprocate laterally by the fourth drive mechanism, which can meet the requirement of the first and second needle beds simultaneously completing large lateral movements.

The third drive mechanism drives the tufted needles on the first needle bed and the first needle holder, and the fourth drive mechanism drives the tufted needles on the second needle bed and the second needle holder to move laterally at a set distance. By moving laterally in one direction or alternating directions, different shapes of rhombuses, hearts, or other self-designed lawn patterns or shapes, as well as lawn products of different colors, can be produced during continuous flocking operation. In the second working state, the tufting needles installed at the bottom of the first needle bed and the tufting needles installed at the bottom of the second needle bed are respectively inserted with grass yarn of different colors. The oil tank and the flocking mechanism installed in the oil tank, consisting of the first drive mechanism, the second drive mechanism, etc., are driven by the oil tank lateral movement mechanism to move back and forth along the front and back of the lawn machine, so that the first needle bed and the second needle bed can be accurately changed to the working position.

[0015] The first needle holder of this utility model is detachably installed on the rear side of the first needle bed, and the second needle holder is detachably installed on the front side of the second needle bed. Therefore, it is very convenient to adjust the distance between the tufted needles on two adjacent first needle holders and to adjust the distance between the tufted needles on two adjacent second needle holders.
[0016] This invention can not only produce rectangular strip lawn patterns and square block lawn patterns, but also produce lawn patterns of different shapes such as rhombuses, hearts, and more, thus better meeting users' needs for ordinary pattern lawns and multi-pattern fancy lawns.
[0017] This utility model has a simple structure, is easy to implement, has low manufacturing cost, and allows for convenient and accurate switching between the first and second needle beds. Attached Figure Description

This mechanism drives the oil tank 10 and the flocking mechanism, consisting of a first drive mechanism 3, a second drive mechanism 4, etc., installed within the oil tank 10. The entire assembly reciprocates laterally along the front-to-back direction of the lawnmower, allowing the first needle bed 1 and the second needle bed 2 to accurately change to their working positions. During the continuous operation of the fork pull, the lateral movement of the oil tank, and the up-and-down movement of the first or second needle bed 2 for flocking, rectangular strip lawn patterns, square block lawn patterns, and lawn products of different colors can be produced. Figure 17 Only rectangular strip-shaped lawn patterns are shown.
[0048] After trial use, this utility model can not only produce products with rectangular strip lawn patterns and square block lawn patterns, but also produce lawn products with different shapes such as rhombus, heart, triangle, T, L or other self-designed lawn patterns or shapes, and different colors. It can better meet users' needs for ordinary pattern lawns and multi-pattern fancy lawns. Moreover, it has a simple structure, is easy to implement, and has low manufacturing cost, achieving good results.
